In the above equations, Fx represents a load (N) applied in the boundary line perpendicular direction D2 to a part in which the first fabric 10 and the second fabric 20 are laminated to the belt-shaped member 30 (hereinafter, also referred to as “laminated part 61”), Lx represents a displacement (mm) when a load is applied to the laminated part 61 in the boundary line perpendicular direction D2, Fy represents a load (N) applied to the laminated part 61 in the boundary line parallel direction D1, Ly represents a displacement (mm) when a load is applied to the laminated part 61 in the boundary line parallel direction D1, Fb1x represents a load (N) applied to the first fabric 10 in the boundary line perpendicular direction D2, Lb1x represents a displacement (mm) when a load is applied to the first fabric 10 in the boundary line perpendicular direction D2, Fb2x represents a load (N) applied to the second fabric 20 in the boundary line perpendicular direction D2, Lb2x represents a displacement (mm) when a load is applied to the second fabric 20 in the boundary line perpendicular direction D2, Fb1y represents a load (N) applied to the first fabric 10 in the boundary line parallel direction D1, Lb1y represents a displacement (mm) when a load is applied to the first fabric 10 in the boundary line parallel direction D1, Fb2y represents a load (N) applied to the second fabric 20 in the boundary line parallel direction D1, and Lb2y represents a displacement (mm) when a load is applied to the second fabric 20 in the boundary line parallel direction D1, respectively.
The Fx, Fy, Fb1x, Fb2x, Fb1y, and Fb2y are preferably the loads up to the maximum elongation in a load-elongation curve drawn with the load on the vertical axis and the elongation on the horizontal axis, which is a relationship between the load applied to the laminated part 61, the first fabric 10, and the second fabric 20 in each of the boundary line perpendicular direction D12 and the boundary line parallel direction D1 and the elongation of the laminated part 61, the first fabric 10, and the second fabric 20 when each of the loads is applied. By setting the values of the Fx, Fy, Fb1x, Fb2x, Fb1y, and Fb2y in this way, each of the values of ktx, kty, kb1x, kb1y, kb2x, and kb2y can be calculated accurately.
The Fx, Fy, Fb1x, Fb2x, Fb1y, and Fb2y are preferably the loads in a region of initial deformation in which a load and a displacement are proportional to each other in a load-elongation curve drawn with the load on the vertical axis and the elongation on the horizontal axis, which is a relationship between the load applied to the laminated part 61, the first fabric 10, and the second fabric 20 in each of the boundary line perpendicular direction 1D2 and the boundary line parallel direction D1 and the elongation of the laminated part 61, the first fabric 10, and the second fabric 20 when each of the loads is applied. That is, the Fx, Fy, Fb1x, Fb2x, Fb1y, and Fb2y are preferably the values in a region of initial deformation in which a load and a displacement are proportional to each other in each sample. By setting the values of the Fx, Fy, Fb1x, Fb2x, Fb1y, and Fb2y in this way, the ktx, kty, kb1x, kb1y, kb2x, and kb2y can be compared more precisely.
The Fx, Fy, Fb1x, Fb2x, Fb1y, and Fb2y may be the same values as each other. That is, the Lx, Ly, Lb1x, Lb2x, Lb1y, and Lb2y may be respective displacements when the same load is applied to the laminated part 61, the first fabric 10, and the second fabric 20 in each of the boundary line perpendicular direction D2 and the boundary line parallel direction D1. When the sizes of respective samples of the laminated part 61, the first fabric 10, and the second fabric 20 are the same as each other and the values of the Fx, Fy, Fb1x, Fb2x, Fb1y, and Fb2y are the same values as each other, the displacement can be measured without changing the setting, conditions, or the like of a testing machine according to each sample, so that the measurement of each displacement becomes easy.
The garment 1 includes the first fabric 10, the second fabric 20, and the belt-shaped member 30.
As the kind of the first fabric 10, for example, a woven fabric of a plain weave, a twill weave, a satin weave, or the like; a knit fabric of plain knitting, rib knitting, garter knitting, or the like; a nonwoven fabric; or the like can be mentioned. Among them, the first fabric 10 is preferably a knit fabric, and more preferably a knit fabric of rib knitting. By constituting the first fabric 10 in this way, the stretchability of the first fabric 10 can be enhanced.
The first fabric 10 may have multiple knit structures or weave structures. As a specific example, a constitution in which different kinds of knit structures such as rib knitting and mesh knitting are included in the first fabric 10, or the like can be mentioned. By including multiple knit structures or weave structures in the first fabric 10, the characteristics can be changed by a part of the first fabric 10. For example, the whole knit structure of the first fabric 10 is formed by rib knitting, so that the whole stretchability of the first fabric 10 is enhanced, and the first fabric 10 is fitted to the body of the wearer. The knit structure in the vicinity of the side of the first fabric 10 is formed by mesh knitting, so that the air-permeability in the vicinity of the side in which heat is easy to be accumulated is enhanced, and the wear comfort of the garment 1 can be improved.
Examples of the material for the fiber constituting the first fabric 10 include a synthetic fiber such as polyester, polyurethane, and nylon; and a natural fiber such as cotton and hemp. Among them, the material for the fiber constituting the first fabric 10 is preferably a synthetic fiber, and more preferably polyester. By constituting the first fabric 10 in this way, the joining strength with the belt-shaped member 30 can be enhanced, and the garment 1 is easily produced.
The thickness of the first fabric 10 is preferably 0.5 mm or more, more preferably 0.7 mm or more, furthermore preferably 1 mm or more, and particularly preferably 1.2 mm or more. By setting the lower limit value of the thickness of the first fabric 10 in this way, the joining strength with the belt-shaped member 30 is enhanced, and the strength of a joining part 60 can be enhanced. The upper limit value of the thickness of the first fabric 10 is not particularly limited, and can be set to be, for example, 10 mm or less, 5 mm or less, or 3 mm or less. In this regard, the thickness of the first fabric 10 is obtained by measuring the thicknesses in arbitrary multiple parts of the first fabric 10, and then by averaging the obtained multiple values of the thickness.
As the kind of the second fabric 20, a woven fabric, a knit fabric, a nonwoven fabric, or the like can be mentioned, as in the case of the kind of the first fabric 10, and among them, the second fabric 20 is preferably a knit fabric, and more preferably a knit fabric of rib knitting. By constituting the second fabric 20 in this way, the second fabric 20 having the favorable stretchability can be obtained. In addition, the second fabric 20 may have multiple knit structures or weave structures, as in the case of the first fabric 10.
Examples of the material for the fiber constituting the second fabric 20 include a synthetic fiber and a natural fiber as in the case of the material for the fiber constituting the first fabric 10, and among them, the material is preferably a synthetic fiber, and preferably polyester. By constituting the second fabric 20 in this way, the joining strength between the second fabric 20 and the belt-shaped member 30 is enhanced, and the second fabric 20 and the belt-shaped member 30 is easily joined.
The thickness of the second fabric 20 is, as in the case of the thickness of the first fabric 10, preferably 0.5 mm or more, more preferably 0.7 mm or more, furthermore preferably 1 mm or more, and particularly preferably 1.2 mm or more. By setting the lower limit value of the thickness of the second fabric 20 in this way, the joining strength between the second fabric 20 and the belt-shaped member 30 can be enhanced, and the strength of the joining part 60 can be increased. The upper limit value of the thickness of the second fabric 20 is not also particularly limited, as in the case of the first fabric 10, and can be set to be, for example, 10 mm or less, 5 mm or less, or 3 mm or less. In this regard, the thickness of the second fabric 20 is obtained by measuring the thicknesses in arbitrary multiple parts of the second fabric 20, and then by averaging the obtained multiple values of the thickness.
The first fabric 10 and the second fabric 20 may be fabrics of different kinds or materials, but are preferably fabrics of the same kind or material. By using the same kind or material for the first fabric 10 and the second fabric 20, the physical properties of the first fabric 10 and the second fabric 20 are equalized, and a joining step of the first fabric 10 and the second fabric 20 is easily performed. In addition, the first fabric 10 and the second fabric 20 are preferably knit fabrics of synthetic fiber, and more preferably rib knitting of polyester. By constituting the first fabric 10 and the second fabric 20 in this way, the garment 1 that is excellent in the stretchability and has the joining part 60 with high strength can be obtained.
As the kind of the belt-shaped member 30, a woven fabric of a plain weave, a twill weave, a satin weave, or the like; a knit fabric of plain knitting, rib knitting, garter knitting, or the like; a nonwoven fabric; or a material obtained by coating these fabrics with a synthetic resin can be mentioned. Among them, the kind of the belt-shaped member 30 is preferably a knit fabric. By forming the belt-shaped member 30 with a knitted fabric, the stretchability can be imparted to the belt-shaped member 30, and the stretchability can also be imparted to the joining part 60. In addition, because the belt-shaped member 30 has favorable skin touch, the garment 1 that is comfortable to the wearer can be obtained.
Examples of the material for the fiber constituting the belt-shaped member 30 include a synthetic fiber such as polyester, polyurethane, and nylon; and a natural fiber such as cotton and hemp. Among them, the material for the fiber constituting the belt-shaped member 30 is preferably a synthetic fiber, and more preferably polyurethane. By constituting the belt-shaped member 30 in this way, the joining strength with the first fabric 10 and the second fabric 20 is increased, and the productivity of the garment 1 can be enhanced. In addition, the stretchability of the belt-shaped member 30 can also be enhanced.
As shown in
The boundary between the first fabric 10 and the second fabric 20 is preferably located in a central part of the belt-shaped member 30, The expression “central part” of the belt-shaped member 30 is referred to as the center region of the width of belt-shaped member 30 divided into three equal regions. By arranging the first fabric 10 and the second fabric 20 in such a position of the belt-shaped member 30, the joining strength between the first fabric 10 and the belt-shaped member 30 as well as the joining strength between the second fabric 20 and the belt-shaped member 30 can be enhanced, and the garment 1 that has favorable production efficiency and excellent durability can be obtained.
As shown in
At least one of the first fabric 10 and the second fabric 20 has a larger elongation in a direction perpendicular to a direction parallel to a boundary line between the first fabric 10 and the second fabric 20 (boundary line perpendicular direction D2) than an elongation in the direction parallel to the boundary line between the first fabric 10 and the second fabric 20 (boundary line parallel direction D1). That is, at least one of the first fabric 10 and the second fabric 20 has a larger elongation in a circumferential direction of the body of the wearer than an elongation in a vertical direction that is a direction from the head to the foot of the wearer. By constituting at least one of the first fabric 10 and the second fabric 20 in this way, the garment 1 that is easily fitted to the body of the wearer is obtained. In the present invention, “perpendicular” means 80 degrees-100 degrees. It is not necessary to have the larger elongation in the boundary line perpendicular direction D2 than in the boundary line parallel direction D1 in all of 80 degrees-100 degrees, and the larger elongation in the boundary line perpendicular direction D2 than in the boundary line parallel direction D1 at an angle of the identification of 80 degrees-100 degrees.
It is sufficient that at least one of the first fabric 10 and the second fabric 20 has a larger elongation in the boundary line perpendicular direction D2 than an elongation in the boundary line parallel direction D1; however, it is preferred that the first fabric 10 and the second fabric 20 have a larger elongation in the boundary line perpendicular direction D2 than an elongation in the boundary line parallel direction D1. By constituting the first fabric 10 and the second fabric 20 in this way, the stretchability of the garment 1 can be further enhanced, and the garment 1 becomes easy to follow the motion of the body of the wearer.
In the garment 1, the ktx and kty that are solutions of the following equations have a relationship of ktx>kty. In addition, the kb1x, kb1y, kb2x, and kb2y that are solutions of the following equations have a relationship of at least one of kb1x<kb1y and kb2x<kb2y.

In the above equations, Fx represents a load (N) applied in the boundary line perpendicular direction D2 to a part in which the first fabric 10 and the second fabric 20 are laminated to the belt-shaped member 30 (laminated part 61), Lx represents a displacement (mm) when a load is applied to the laminated part 61 in the boundary line perpendicular direction D2, Fy represents a load (N) applied to the laminated part 61 in the boundary line parallel direction D1, Ly represents a displacement (mm) when a load is applied to the laminated part 61 in the boundary line parallel direction D1, Fb1x represents a load (N) applied to the first fabric 10 in the boundary line perpendicular direction D2, Lb1x represents a displacement (mm) when a load is applied to the first fabric 10 in the boundary line perpendicular direction D2, Fb2x represents a load (N) applied to the second fabric 20 in the boundary line perpendicular direction D2, L2x represents a displacement (mm) when a load is applied to the second fabric 20 in the boundary line perpendicular direction D2, Fb1y represents a load (N) applied to the first fabric 10 in the boundary line parallel direction D1, Lb1y represents a displacement (mm) when a load is applied to the first fabric 10 in the boundary line parallel direction D1, Fb2y represents a load (N) applied to the second fabric 20 in the boundary line parallel direction D1, and Lb2y represents a displacement (mm) when a load is applied to the second fabric 20 in the boundary line parallel direction D1, respectively.
After the measurement of Lx, Ly, Lb1x, Lb2x, Lb1y, and Lb2y, the ktx, kty, kb1x, kb1y, kb2x, and kb2y that are solutions of the above equations are calculated, and a relationship between the ktx and the kty, a relationship between the kb1x and the kb1y, and a relationship between the kb2x and the kb2y are determined.
By having the fact that the ktx and kty that are solutions of the above equations satisfy a relationship of ktx>kty, and that the kb1x, kb1y, kb2x, and kb2y satisfy a relationship of at least one of kb1x<kb1y and kb2x<kb2y, the garment 1 that is excellent in the stretchability in the boundary part between the first fabric 10 and the second fabric 20, easy to follow the motion of the body of the wearer, and comfortable during exercise can be obtained.
In addition, when a garment is made without sewing, in order to make the garment beautifully finished, it is required to apply tension to a fabric at the time of joining the fabric. If a fabric having a high elongation is used in order to obtain a garment having excellent stretchability, the fabric is excessively elongated in the joining step of each fabric, and it may be difficult to obtain a beautiful finish or may be insufficient in the joining of each fabric. The ktx and kty have a relationship of ktx>kty, whereas the kb1x, kb1y, kb2x, and kb2y have a relationship of at least one of kb17<kb1y and kb2x<kb2y, so that the belt-shaped member 30 prevents the first fabric 10 and the second fabric 20 from being excessively elongated, the joining strength with the first fabric 10 and the second fabric 20 is enhanced, and the production efficiency of the garment 1 can be increased.
It is sufficient that the kb1x, kb1y, kb2x, and kb2y have a relationship of at least one of kb1x<kb1y and kb2x<kb2y; however, it is preferred to have a relationship of kb1x<kb1y and kb2x<kb2y. By having the fact that the kb1x, kb1y, kb2x, and kb2y satisfy such a relationship, the stretchability in the boundary part between the first fabric 10 and the second fabric 20 can be enhanced, and the garment 1 is easily fitted to the body of the wearer. In addition, also in the joining step of the first fabric 10 and the belt-shaped member 30 as well as the second fabric 20 and the belt-shaped member 30, the joining is easily performed, and the productivity of the garment 1 can be enhanced.
In a case where the garment 1 has a hood 5, the hood 5 is constituted of multiple fabrics, and the belt-shaped member 30 is preferably arranged along the boundary between the fabrics. That is, the belt-shaped member 30 is joined to each of the fabrics constituting the hood 5, and each of the fabrics constituting the hood 5 is preferably joined to each other with the belt-shaped member 30. By constituting the hood 5 with multiple fabrics, the hood 5 is easily fitted to the head of the wearer. By arranging the belt-shaped member 30 along the boundary between the fabrics constituting the hood 5, even when the hood 5 is fitted to the head of the wearer, the surface of the joining part between the fabrics constituting the hood 5 becomes smooth, and a sense of discomfort is hardly given to the wearer.
In a case where the garment 1 has the hood 5, the belt-shaped member 30 is preferably arranged along the boundary between the hood 5 and the first fabric 10. That is, the fabric constituting the hood 5 and the first fabric 10 are preferably joined by the belt-shaped member 30. By arranging the belt-shaped member 30 along the boundary between the hood 5 and the first fabric 10, unevenness is hardly formed in the joining part between the hood 5 and the first fabric 10, and the garment 1 that has favorable skin contact can be obtained.
In a case where the garment 1 has the second fabric 20a on the right side in a right front panel and the second fabric 20b on the left side in a left front panel, the garment 1 may have an engagement member engaging the second fabric 20a on the right side with the second fabric 20b on the left side. Examples of the engagement member include a zip fastener, and a hook and loop fastener. In addition, the engagement member may be provided, for example, in an opening of a pocket or the like of the garment 1. As the method for joining the engagement member to the first fabric 10 or the second fabric 20, for example, sewing, welding by ultrasonic waves or heat, bonding by an adhesive, or the like can be mentioned. Among them, as the method for joining the engagement member, sewing is preferred. By joining the engagement member to the first fabric 10 or the second fabric 20 by sewing, the bonding strength between the engagement member and the first fabric 10 or second fabric 20 can be enhanced. Therefore, even if stress is applied to the joining part between the engagement member and the first fabric 10 or the second fabric 20 at the time of engaging or separating the engagement member, the engagement member is hardly removed from the first fabric 10 or the second fabric 20.
In this regard, in the joining part between the engagement member and the first fabric 10 or the second fabric 20, it is preferred to arrange a belt-shaped member 30. By arranging the belt-shaped member 30 in the joining part between the engagement member and the first fabric 10 or the second fabric 20, the surface of the joining part of the engagement member is made smooth, and the joining part of the engagement member hardly gives a sense of discomfort to the body of the wearer.
The ktx kb1x and kb2x that are solutions of the above equations preferably have a relationship of at least one of ktx>kb1x and ktx>kb2x. By having the fact that the ktx, kb1x and kb2x satisfy such a relationship, the stretchability of the garment 1 is improved, and the garment 1 that hardly hinders the motion of the body of the wearer during exercise can be obtained. In addition, also in the production of the garment 1, the joining part 60 between the first fabric 10 and the second fabric 20 is prevented from being excessively elongated, and the production efficiency of the garment 1 can be enhanced.
In addition, the ktx, kb1x and kb2x preferably have a relationship of ktx>kb1x and ktx>kb2x. By having the fact that the ktx, kb1x and kb2x satisfy such a relationship, the stretchability of the garment 1 can be further enhanced, and the garment 1 becomes easy to follow the body of the wearer.
The ktx and kty that are solutions of the above equations have preferably a ratio of 1.5 or more, more preferably a ratio of 1.7 or more, and furthermore preferably a ratio of 2 or more. In this regard, the ratio of the ktx and kty is calculated by a calculation formula of ktx/kty. By setting the lower limit value of the ratio of the ktx and kty in this way, the stretchability in the joining part 60 is enhanced, and the garment 1 that is easy to follow the body of the wearer can be obtained. The upper limit value of the ratio of the ktx and kty is not particularly limited, and can be set to be, for example, 10 or less, 8 or less, or 5 or less.
At least one of the first fabric 10 and the second fabric 20 has a ratio of an elongation in the boundary line perpendicular direction D2 to an elongation in the boundary line parallel direction D1 of preferably 1.5 or more, more preferably 1.7 or more, and furthermore preferably 2 or more. In this regard, the ratio of an elongation of the first fabric 10 in the boundary line perpendicular direction D2 to an elongation of the first fabric 10 in the boundary line parallel direction D1 is calculated by a calculation formula of the elongation [%] of the first fabric 10 in the boundary line perpendicular direction D2/the elongation [%] of the first fabric 10 in the boundary line parallel direction D1, and the ratio of an elongation of the second fabric 20 in the boundary line perpendicular direction D2 to an elongation of the second fabric 20 in the boundary line parallel direction D1 is calculated by a calculation formula of the elongation [%] of the second fabric 20 in the boundary line perpendicular direction D2/the elongation [%] of the second fabric 20 in the boundary line parallel direction D. By setting the lower limit value of the ratio of the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 to the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line parallel direction D1 in this way, the garment 1 becomes easy to follow the motion of exercise or the like when the garment 1 is worn. The upper limit value of the ratio of the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 to the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line parallel direction D1 is not particularly limited, but can be set to be, for example, 1.0 or less, 8 or less, or 5 or less.
Hereinafter, a garment according to an embodiment 2 of the present invention will be described with reference to the drawings. Basically, the garment according to the embodiment 2 has a constitution similar to the constitution of the garment according to the embodiment 1, and therefore, the description of the common parts will be omitted.
The garment 1 of the embodiment 2 of the present invention is a garment 1 including a first fabric 10, a second fabric 20, and a belt-shaped member 30, and is characterized in that the first fabric 10 is in a back panel 3, the second fabric 20 is in a front panel 2, at least one of the front panel 2 and the back panel 3 includes a fabric having a larger elongation than an elongation of at least one of the first fabric 10 and the second fabric 20 in a direction (hereinafter, also referred to as “boundary line perpendicular direction D12”) perpendicular to a direction parallel to a boundary line between the first fabric 10 and the second fabric 20 (hereinafter, also referred to as “boundary line parallel direction D1”) in at least a part of from a lower part of an armhole 71 to a boundary between the first fabric 10 and the second fabric 20, and the belt-shaped member 30 is arranged along the armhole 71 of at least one of the first fabric 10 and the second fabric 20,
As shown in
The fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D12 preferably has a larger elongation than an elongation of each of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2. By constituting the fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 in this way, the stretchability of the armhole 71 can be further enhanced, and the wear comfort of the garment 1 during exercise can be enhanced.
As the method for forming the fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2, for example, a method of forming a knit structure or weave structure having higher stretchability than the stretchability of at least one of the first fabric 10 and the second fabric 20, a method of using a material having higher stretchability than the stretchability of at least one of the first fabric 10 and the second fabric 20, or the like can be mentioned.
The fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 may be joined to at least one of the first fabric 10 in the back panel 3 and the second fabric 2 in the front panel 2 by welding, sewing, or the like, and it is preferred that the fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 is included in the fabric constituting at least one of the first fabric 10 and the second fabric 20, by partially changing the knit structure or weave structure of at least one of the first fabric 10 and the second fabric 20. That is, the fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2, and at least one of the first fabric 10 and the second fabric 20 are preferably integrally constituted. By constituting the fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 and at least one of the first fabric 10 and the second fabric 20 in this way, unevenness or the like due to the joining is hardly formed in the boundary part of the fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2, and therefore, the garment 1 that has favorable skin contact can be obtained.
The fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 preferably has higher air-permeability than the air-permeability of at least one of the first fabric 10 and the second fabric 20. Since heat is easy to be accumulated between the fabric in the lower part of the armhole 71 and the wearer, for example, use of a fabric 41a having higher air-permeability than the air-permeability of at least one of the first fabric 10 and the second fabric 20, such as a mesh knit fabric, as the fabric 41 having a larger elongation than the elongation of at least one of the first fabric 10 and the second fabric 20 in the boundary line perpendicular direction D2 can improve the wear comfort of the garment 1.
The belt-shaped member 30 is arranged along the armhole 71 of at least one of the first fabric 10 and the second fabric 20. Since the armhole 71 is a part that comes into contact with the side of the wearer, particularly, it is required to improve the skin contact in this part. By arranging the belt-shaped member 30 along the armhole 71 of at least one of the first fabric 10 and the second fabric 20, the surface of the armhole 71 is made smooth, and the garment 1 that is comfortable to the wearer can be obtained.
The first fabric 10 and the second fabric 20 preferably have knit structures different from each other. By forming the knit structures of the first fabric 10 and the second fabric 20 different from each other, a function suitable for each part of the garment 1 can be imparted. For example, since heat is easy to be accumulated in a back part of an upper garment that is the garment 1, use of a knit structure having high air-permeability such as mesh knitting for the first fabric 10 in the back panel 3 can be mentioned.
At least one of the first fabric 10 and the second fabric 20 preferably has multiple knit structures. Specifically, for example, a constitution in which multiple different kinds of knit structures such as rib knitting and mesh knitting are included in the first fabric 10 can be mentioned. By including multiple knit structures in at least one of the first fabric 10 and the second fabric 20, adequate characteristics can be imparted to each part of the first fabric 10 or the second fabric 20. For example, by forming the whole knit structure of the first fabric 10 with rib knitting, the whole stretchability of the first fabric 10 is enhanced, and the first fabric 10 is fitted to the body of the wearer, and further, by forming the knit structure in the vicinity of the side of the first fabric 10 with mesh knitting, the air-permeability in the vicinity of the side in which heat is easy to be accumulated is enhanced, and thus the wear comfort of the garment 1 can be improved.
It is preferred that at least one of the first fabric 10 and the second fabric 20 has multiple knit structures, and it is more preferred that each of the first fabric 10 and the second fabric 20 has multiple knit structures, By including multiple knit structures in each of the first fabric 10 and the second fabric 20, a function that is required in each part in the whole body of the wearer can be imparted, and a more functional garment can be obtained as the garment 1.
A fabric 41b having a larger elongation than the elongation of the first fabric 10 in the boundary line perpendicular direction D2 is preferably included in the central part of the back panel. By constituting the back panel 3 in this way, the stretchability in the back part of an upper garment that is the garment 1 is enhanced, and the upper garment that is fitted to the wearer can be obtained.
The fabric 41b having a larger elongation than the elongation of the first fabric 10 in the boundary line perpendicular direction D2 may be arranged in a shoulder part of the second fabric 20. By constituting the second fabric 20 in this way, the stretchability can be imparted to the fabric in the shoulder part of the front panel 2, which is easily pulled according to the pulling of fabric at the time of motion such as turning the arm, and thus the garment 1 that has favorable wearing feeling can be obtained.
It is preferred to include a longitudinal direction extension part 52 having a larger elongation in the direction D4 perpendicular to the longitudinal direction D3 of the sleeve 4 than the elongation in the longitudinal direction of the sleeve 4, on both of the upper and lower sides in the longitudinal direction of the sleeve 4 in the longitudinal perpendicular direction extension part 51. With the garment 1 having the sleeve 4 that is constituted in this way, the sleeve 4 is fitted to the arm of the wearer, and thus can follow the motion of the wearer.
As the longitudinal perpendicular direction extension part 51, for example, a knit structure of garter knitting or the like can be used. In addition, as the longitudinal direction extension part 52, for example, a knit structure of rib knitting or the like can be used.
As for the longitudinal perpendicular direction extension part 51 and the longitudinal direction extension part 52, a fabric constituting the longitudinal perpendicular direction extension part 51 and a fabric constituting the longitudinal direction extension part 52 may be joined to the sleeve fabric 50 by welding, sewing, or the like; however, it is preferred that by partially changing the knit structure or weave structure of the sleeve fabric 50, the longitudinal perpendicular direction extension part 51 and the longitudinal direction extension part 52 are included in a fabric constituting the sleeve fabric 50. That is, the sleeve fabric 50, the longitudinal perpendicular direction extension part 51 and the longitudinal direction extension part 52 are preferably integrally constituted. By constituting the sleeve fabric 50 in this way, the unevenness due to the joining can be reduced in each of the boundary parts between the sleeve fabric 50 and the longitudinal perpendicular direction extension part 51, and between the sleeve fabric 50 and the longitudinal direction extension part 52, and therefore, the skin contact of the sleeve 4 can be improved.
The fabric constituting the sleeve fabric 50 preferably has a larger elongation in the longitudinal direction D3 of the sleeve 4 than the elongation in the direction D4 perpendicular to the longitudinal direction.
By constituting the sleeve fabric 50 in this way, a sleeve 4 having high followability to the arm during exercise of swinging the arms back and forth, such as jogging can be obtained. As a result, cuffs are hardly turned up during exercise.
It is preferred that the garment 1 has a sleeve, the sleeve contains a rib knitting part 53, and a longitudinal direction of a furrow 53a of the rib knitting part 53 is not parallel to an axial direction of the sleeve. The expression “axis direction of the sleeve” is referred to as an extending direction of the axis passing through a plane A containing at least a part of a lower end part of a cuff of the sleeve, and a plane B containing an upper end part of the sleeve and being parallel to the plane A. The expression. “longitudinal direction of a furrow 53a of the rib knitting part 53 is not parallel to an axial direction of the sleeve” is referred to as an angle of exceeding 0 degree formed by the longitudinal direction of the furrow 53a of the rib knitting part 53 and the axis direction of the sleeve. By constituting the sleeve in this way, the sleeve becomes easy to follow the motion of putting the arm forward. Therefore, during exercise of swinging the arms back and forth, the garment 1 that is particularly comfortable to the wearer can be obtained.
The angle formed by the longitudinal direction of the furrow 53a of the rib knitting part 53 and the axis direction of the sleeve is preferably 1 or more degrees, more preferably 3 or more degrees, and furthermore preferably 5 or more degrees. By setting the lower limit value of the angle formed by the longitudinal direction of the furrow 53a of the rib knitting part 53 and the axis direction of the sleeve in this way, the sleeve becomes easy to follow the motion of swinging the arms back and forth, and thus the wear comfort of the garment 1 during exercise can be enhanced. The angle formed by the longitudinal direction of the furrow 53a of the rib knitting part 53 and the axis direction of the sleeve is preferably 45 or less degrees, more preferably 40 or less degrees, and furthermore preferably 35 or less degrees. By setting the upper limit value of the angle formed by the longitudinal direction of the furrow 53a of the rib knitting part 53 and the axis direction of the sleeve in this way, the lower part of the sleeve is easily fitted to the forearm of the wearer.
Hereinafter, preferred embodiments of the garment according to the embodiment 1 and the embodiment 2 of the present invention will be described.
The garment 1 is preferably an outer garment or an intermediate garment. The outer garment is a garment to be worn outermost, and the intermediate garment is a garment to be worn intermediately between an outer garment and an inner garment. The garment 1 is an outer garment or an intermediate garment, and it is preferred to wear, for example, underwear or the like that has favorable water absorbency on the inner side of the garment 1.
The first fabric 10 and the second fabric 20 are preferably joined by welding. Examples of the welding include heat welding, and ultrasonic welding. By joining the first fabric 10 and the second fabric 20 by welding, the joining strength with the first fabric 10 and the second fabric 20 can be enhanced, and the durability of the garment 1 can be enhanced.
The belt-shaped member 30 is preferably pasted in the joining part 60 in which the first fabric 10 and the second fabric 20 are joined by welding. By welding the first fabric 10 and the second fabric 20, a material constituting the first fabric 10 and a material constituting the second fabric 20 are melted and solidified, and therefore, the joining part 60 becomes hard, and the skin touch becomes poor. By pasting the belt-shaped member 30 to the joining part 60, the joining part 60 having poor skin touch is covered with the belt-shaped member 30, and thus the discomfort feeling is hardly given to the wearer when wearing the garment 1.
Hereinafter, the effects of the present invention will be specifically described by way of example. The following example does not limit the present invention, and all of the design changes according to the gist of the foregoing or following description are included in the technical scope of the present invention.
By using the first fabric 10 shown in
From the base part of the first fabric 10 in the back panel 3 of the garment 1, a measurement sample of the first fabric 10 was collected along the boundary line parallel direction D1 and the boundary line perpendicular direction D2. From the laminated part 61 being the joining part 60 between the first fabric 10 and the second fabric 20, in which the first fabric 10 and the second fabric 20 were laminated to the belt-shaped member 30, a measurement sample of the laminated part 61 was collected along the boundary line parallel direction D1 and the boundary line perpendicular direction D2 so as to have the laminated part 61 at the center. The size of each measurement sample was 160 to 180 mm in length and 60 mm in width. Note that in the present example, since the knit structures of the base parts of the first fabric 10 and the second fabric 20 are the same, the measurement sample of the first fabric 10 also serves as the measurement sample of the second fabric 20. In a case where the knit structures of the base parts of the first fabric 10 and the second fabric 20 are different, a measurement sample of the second fabric 20 was collected from the base part of the second fabric 20 in the front panel 2.
A mark was made at the longitudinal center of each measurement sample such that the size of the measurement sample in length was the same as the size of the belt-shaped member 30 in width. In the present example, since the belt-shaped member 30 having a width of 10 mm was used, the marks were made at intervals (hereinafter referred to as the point distance) of 10 mm.
By using a tensile testing machine, the measurement sample of the first fabric 10 was pulled in the boundary line parallel direction D1, and a displacement Lb1y of the measurement sample of the first fabric 10 in the boundary line parallel direction D1 was measured. Specifically, the measurement sample of the first fabric 10 was fixed to a gripping tool such that the distance between the gripping tools was 100 mm, a load Fb1y was applied to the measurement sample of the first fabric 10 in the boundary line parallel direction D1, and the increased distance of the point distance between the marks made to the measurement sample of the first fabric 10 was measured. The tensile rate of the measurement sample of the first fabric 10 was set to be 200 mm/min. As the measurement device, for example, Table-Top Type Autograph AGS-X 1 kN manufactured by Shimadzu Corporation can be used.
In a similar manner as in the measurement of the displacement Lb1y of the measurement sample of the first fabric 10 in the boundary line parallel direction D1, a displacement Lb1x of the measurement sample of the first fabric 10 in the boundary line perpendicular direction D2, a displacement Ly of the measurement sample of the laminated part 61 in the boundary line parallel direction D1, and a displacement Lx of the measurement sample of the laminated part 61 in the boundary line perpendicular direction D2 were measured. The measurement results are shown in Table 1.
The loads of Fb1y, Fb1x, Fy, and Fx applied to the measurement sample and the displacements of Lb1y, Lb1x, Ly, and Lx were substituted into the following equations, and the ktx, kty, kb1x, and kb1y that are solutions of the following equations were calculated. As described above, in the present example, the knit structures of the base parts of the first fabric 10 and the second fabric 20 were the same. Therefore, it was considered that the values of the kb1x and kb1y being solutions of the equations for the first fabric 10 were the same as the values of kb2x and kb2y, and the measurement of displacement and the calculation of solution were performed for the measurement sample of the first fabric 10. In a case where the knit structures of the base parts of the first fabric 10 and the second fabric 20 were different, also for the second fabric 20, similarly as in the first fabric 10, the loads of Fb2y and Fb2y, were applied to the measurement sample of the second fabric 20, and the displacements of Lb2y and Lb2x were measured and the solutions of kb2x and kb2y were calculated.
