The present invention relates to pants effective for supporting the buttocks.
Highly stretchable pants are comfortable to wear but cannot create a beautiful silhouette. Especially since they cannot control the abdomen or the buttocks, the wearer's body shape is often revealed, not allowing a beautiful shape to be created. Further, if a controlling undergarment such as a girdle is worn under the pants, a body shape can be created, but since such underwear squeezes the wearer's body, it is not comfortable to wear. To solve these problems, recently pants and skirts with stretchable lining fabrics sewn to their wrong sides intended for body shaping are abundantly commercially available.
On the other hand, the prior art proposals include pants with a power net fabric sewn to the wrong side of the back body (see Patent Document 1), pants or a skirt having a girdle suspended inside (see Patent Document 2), pants in which any of variously formed stretchable knit lining fabrics intended for body shaping is sewn to the front and back bodies inside the pants (see Patent Documents 3, 4, 5 and 6), etc.
However, the pants with a power net fabric sewn to the wrong side of the back body, described in Patent Document 1, are little effective for supporting the buttocks, since the lining fabric and the garment fabric are almost dimensionally equal to each other.
On the other hand, the pants or a skirt having a girdle suspended inside, described in Patent Document 2, is less comfortable to wear and cannot be easily put on or taken off, though it can give the same effect as given by a tightly controlling undergarment. Further, Patent Documents 3, 4 and 5 are respectively intended to provide an effect of supporting the buttocks by overlaying and sewing a V-shaped powerful power net, but joining or sewing it is troublesome while the intended effect remains small for the troublesome effort. Patent Document 6 discloses pants having a non-stretchable belt-like patch applied to a highly stretchable lining fabric. However, since the patch is non-stretchable, the buttocks shape tends to be disfigured.
Furthermore, there are commercially available pants with body shaping patches, and when those with a lining fabric for the back body only and those with a lining fabric for the front body only, respectively sewn at sides, were worn experimentally, they were twitched at the sewn portions awkwardly.
The object of this invention is to overcome the disadvantages of the prior art as described above, by providing pants that look like ordinary pants, are effective for supporting the buttocks, further can shape the region ranging from the sides to the abdomen of the wearer, and are excellent in wearing comfort.
To achieve the aforesaid object, the pants of this invention comprise the following constitutions.
(1) Pants, characterized in that a lining fabric covering the region ranging from the buttock portion of the back body through the sidelines to partial portions of the front body is attached inside the garment fabric of the front and back bodies.

(13) Pants, according to (12), wherein the lining fabric and the buttocks supporting patch have extension rates in a range from 30 to 200% and extension recovery rates in a range from 80 to 100%, and they are almost equal to each other in extension rate and extension recovery rate.
(14) Pants, according to (12) or (13), wherein a satin net with a bursting strength of 200 to 260 kPa is used as the lining fabric and a power net with a bursting strength of 261 to 320 kPa is used as the buttocks supporting patch.
(15) Pants, according to anyone of (12) through (14), wherein the width of the buttocks supporting patch gradually increases from a range of 4 to 7 cm at the back center to a range of 5 to 10 cm at the ends of the buttocks supporting patch on the front body.
(16) Pants, according to any one of (1) through (6), wherein a belt-like abdomen suppressing patch for covering the region from the crotch to the waist portion of the front body is attached to the wrong side of the garment fabric.
(17) Pants, according to (16), wherein the belt-like abdomen suppressing patch is sewn to the garment fabric and the lining fabric at the waist portion of the front body and at the crotch and is formed to be continuous from the back body.

This invention can provide pants that look like ordinary pants, are effective for supporting the buttocks, can be used for shaping the sides and the abdomen and are excellent in wearing comfort. Especially even when the pants are light or white colored, the underwear lines are not noticeable from outside.
Further, in another mode of this invention, the pants have not only a buttocks supporting effect but also an abdomen shaping effect.
The pants of this invention are described below in detail in reference to the first to third embodiments shown in the drawings.
The pants of this invention can lift the buttocks upward and obliquely forward from the gluteal fold, since the lining fabric 3 covering the region ranging from the buttock portion of the back body 2 through the sidelines 4 to partial portions of the front body 1 is joined to the garment fabric at the waistline 5 and the crotch 6 inside the garment fabric of the front and back bodies as shown in
Moreover, if the lining fabric 3 is sewn to partial portions of the side seam allowances 14 of the garment fabric through the fasteners 10 as shown in
In the pants of this invention, if woven or knitted fabrics stretchable in the warp yarns direction and/or the weft yarns direction are used as the garment fabric and/or the lining fabric 3, remarkable effects can be obtained in all of wearing comfort, motion allowance and appearance.
The stretchable woven or knitted fabrics include a stretchable woven fabric, etc. formed by using elastic fibers (polyurethane fibers, etc.) together with natural fibers such as cotton or wool, regenerated fibers such as rayon, or synthetic fibers such as acrylic fibers or polyester fibers. Further, usable is a polyester-based stretchable woven fabric in which composite multi-filaments, each consisting of a polyester mainly composed of polytrimethylene terephthalate (hereinafter abbreviated as PPT) and another polyester bonded to each other side by side to extend in the filament length direction, are used as at least either the warp yarns or the weft yarns. Side-by-side composite fibers, in which polymers different in intrinsic viscosity, components, copolymerization ratio, etc. are bonded to each other, are crimped due to the differences in elasticity recovery characteristics and shrinkage characteristics. In the case of side-by-side composite fibers involving fibers different in intrinsic viscosity, stress is concentrated in the fiber component higher in intrinsic viscosity when the fibers are spun or stretched, and the two components are differently internally strained. For this reason, due to the difference in elasticity recovery rate after stretching and the difference in heat shrinkage in the heat treatment of the woven fabric, the component higher in intrinsic viscosity shrinks more greatly, and the single fibers are internally strained and three-dimensionally crimped to form coils. It can be said that the diameter of the three-dimensional coils and the number of coils per unit fiber length are decided by the difference in shrinkage (including the difference in elasticity recovery rate) between the component higher in intrinsic viscosity (highly shrinkable component) and the component lower in intrinsic viscosity (low shrinkable component). If the shrinkage difference is larger, the coil diameter is smaller and the number of coils per unit fiber length is larger. The coils required to be formed by crimping for a stretchable fabric are such that the diameter of the coils is small, that the number of the coils per unit fiber length is large (excellent extension properties and good looking), that the coils have good fatigue setting resistance (small coil fatigue setting in spite of frequent extension and contraction and long-sustained stretchability), and that the hysteresis loss of the coils at the time of extension recovery is small (excellent resiliency and good fit). A stretchable fabric excellent in total balance satisfies all of these requirements and has the properties of polyesters such as appropriate firmness, drapability and high color fastness. To satisfy these properties, it is preferred to use a polyester mainly composed of PPT as the highly shrinkable component. PPT refers to a polyester obtained with terephthalic acid as the main acid component and 1,3-propanediol as the main glycol component. The low shrinkable component is not especially limited, if it is a fiber-formable polyester that is good in interfacial adhesion to the highly shrinkable component PPT and stable in yarn formability. Considering mechanical properties, chemical properties and cost, fiber-formable polyethylene terephthalate is preferred.
If a stretchable woven fabric in which the side-by-side composite fiber yarns obtained as described above are used as at least either the warp yarns or the weft yarns requesting stretchability is used for producing the pants of this invention, remarkable effects can be obtained in wearing comfort, motion allowance, appearance, etc. In the case where the stretchable woven fabric is used as the garment fabric of the pants, it is preferred in view of wearing comfort and prevention of shape disfigurement that the extension rate at least in either the direction or the weft yarns direction is 10% to 40% at a load of 1.5 kg and that the extension recovery rate is 60% or higher.
The extension rate expresses the degree of the extensibility of the woven or knitted fabric. If this value is larger, the worn pants can easily follow the movement of the wearer's body and they can be easily put on and taken off. If the garment fabric of the pants has an extension rate of lower than 10%, there is a problem that the worn pants are too tight to allow flexible movement, and on the contrary, if the extension rate is 40% or higher, there is a problem that the wearer's body silhouette is liable to be revealed not allowing the intended shape to be created, though the pants fit the wearer's body.
The extension recovery rate expresses the degree to which the fabric extended in response to the movement of the wearer's body can return to the original state quickly. If this value is larger, the shape disfigurement of the worn pants is small, and the shape of the pants not worn is not so different from the shape of the pants worn. In the pants of this invention, the extension recovery rate of the garment fabric is 60% or higher, preferably 80% or higher. If the extension recovery rate of the garment fabric is lower than 60%, the fabric is not recovered at the projected portions only of the wearer's body such as buttocks and knees, and the garment fabric remains extended to impair its appearance.
In the meantime, the extension rate is measured based on the strip method of the method A (extension at constant rate) of JIS L 1096 (Test Methods for General Woven Fabrics,” and the extension recovery rate is measured based on the strip method of the method A (repeated extension at constant rate) of JIS L 1096 “Test Methods for General Woven Fabrics.” The detailed test methods are described later for the examples.
In this invention, it is preferred that the size of the lining fabric 3 is set to correspond to 99% to 85% of the size of the garment fabric. The size of the lining fabric 3 refers to the width and/or the length of the lining fabric 3. If the size of the lining fabric 3 is set to correspond to 99% to 85% of the size of the garment fabric, the pants can be worn in such a state that the lining fabric 3 is rather pulled. So, the effect of supporting the buttocks can be enhanced. Further, since the dimensional difference from the garment fabric can be covered by the extension rate of the lining fabric, the lining fabric 3 can be kept extended in relation with the garment fabric and the wearer's body. The width and length of the lining fabric 3 in this case refer to the results of measuring the same segments on the paper pattern before the lining fabric is sewn to the garment fabric, as shown in
Further, in the second embodiment of the pants of this invention, as shown in
In both the first embodiment and the second embodiment of the pants of this invention, it is preferred that pieces of the lining fabric 3 attached inside the garment fabric are joined in the back body at least at one place or more and draped to suit the roundness of the buttocks. The draping refers to a method for three-dimensionally finishing a flat fabric to suit the lines of the wearer's body using darts, tucks, yokes, etc. If darts and tucks are contained in the waistline and the crotch, the lining fabric 3 can be attached to suit the roundness of buttocks. On the other hand, since plural sewing allowances are overlaid at the darts and tucks, the sewing allowances appear as level differences on the front side of the pants, to impair the appearance and also to impair the wearing comfort. Therefore, in this invention, it is preferred that the lining fabric 3 is divided into at least two or more pieces to suit the shape of the buttocks and that the pieces of the lining fabric 3 are sewn together to form a shaped lining fabric 3 to be attached to the pants. It is preferred to use highly extensible seams for sewing the pieces of the lining fabric 3 together. To obtain the highly extensible seams, it is preferred to use a sewing method allowing seams to follow the fabric such as zigzag sewing, flatlock sewing, overlock sewing or chain stitch sewing. Furthermore, it is also preferred to use highly extensible sewing machine threads such as polyester wooly yarns, nylon wooly yarns and Resilon yarns as the sewing yarns used for seaming. It is more preferred that highly extensible sewing machine threads are used to form highly extensible seams. On the other hand, fusion bonding without using sewing yarns is also an effective means for sustaining the extension rate.
Further, in the first and second embodiments of the pants of this invention, if a belt-like buttocks supporting patch 8 inclined obliquely upward from below the hipline of the back body toward the front body is attached to the lining fabric 3 attached inside the garment fabric, the effect of tightening the buttocks and sides can be enhanced. Meanwhile, the buttocks supporting patch can be attached by any method such as sewing, joining, adhesion or fusion bonding, but in view of washing durability, skin touch and working efficiency, sewing is preferred. Meanwhile, the buttocks supporting patch 8 can be attached between the garment fabric and the lining fabric 3 as shown in
The lining fabric 3 attached inside the garment fabric of the pants of this invention and the buttocks supporting patch 8 are not especially limited in material. However, considering the dimensional stability, the compatibility with the garment fabric, the invisibility of the lining fabric 3 from outside when the pants are worn, etc., it is preferred to use a woven or knitted fabric formed by using polyurethane fibers (elastic fibers) together with synthetic fibers such as polyamide fibers or polyester fibers as the lining fabric 3 and the buttocks supporting patch 8. Further, without using elastic fibers, a polyester-based stretchable woven fabric mainly composed of PPT can also be used. The weave is not especially limited. In the case of knitted fabric, the knitting method is not especially limited, but in view of retention of buttocks shape, a warp knitted fabric is more suitable than a weft knitted fabric.
As the lining fabric 3 and the buttocks supporting patch 8, it is preferred to use a woven or knitted fabric with an extension rate of 30 to 200% at a load of 1.5 kg at least in either the warp yarns direction or the weft yarns direction and with an extension recovery rate of 80% to 100% after 10 times of repeated extension. If the extension rate of the lining fabric 3 is lower than 30%, the extensibility is too small. So, when the pants are worn, since the lining fabric only is tight, they cannot be smoothly put on or taken off and are less comfortable to wear. If the lining fabric 3 and the buttocks supporting patch 8 are higher than 200% in extension rate, tightness and buttocks supporting effect are too low. Therefore, it is preferred that the lining fabric 3 and the buttocks supporting patch 8 are 30% or higher in extension rate at least in either the warp yarns direction or the weft yarns direction. More preferred is 50% or higher, and further more preferred is 70% or higher.
Further, as the lining fabric 3 and the buttocks supporting patch 8 of this invention, it is preferred to select a material with an extension recovery rate of 80% to 100%. If the extension recovery rate is lower than 80%, the lining fabric 3 only remains extended to disfigure the shape and the tightening effect declines with the increase of wearing times and washing times.
Furthermore, it is preferred to use a satin net with a bursting strength of 200 to 260 kPa as the material of the lining fabric 3. Further, it is preferred to use a power net with a bursting strength of 261 to 320 kPa as the buttocks supporting patch 8. It is preferred that the lining fabric 3 and the buttocks supporting patch 8 are almost equal to each other in extension rate and extension recovery rate, for such reasons that both are improved in following capability, that the stress felt by the wearer during wearing decreases and that such problems as seam damage are unlikely to occur. On the other hand, with regard to bursting strength, it is preferred that the bursting strength of the buttocks supporting patch 8 is higher than that of the lining fabric 3, for partially enhancing the effect of supporting the buttocks.
The bursting strength is measured according to the method A (Mullen method) of JIS L 1018 “Test Methods for Knitted Fabrics,” as described later for the examples.
The satin net referred to here is a kind of warp knitted fabrics, and it is a material used for foundations in general, especially soft girdles and is densely meshed to show a satin-like smooth look and taste, being characteristically glossy on the surface. Further, the power net is also a kind of warp knitted fabrics, but is different from the satin net in knitting method, looking like a net. Since the power net is stronger than the satin net, it is mainly used for such controlling undergarments as brassieres and bodysuits. Therefore, it does not disfigure the buttocks shape. Therefore, it is the best to use the satin net with the slipperiness and the extension rate necessary as a lining fabric as the lining fabric 3 of this invention and to use the power net as the buttocks supporting patch 8 for reinforcing the support of the region ranging from the gluteal fold through the sides to the abdomen.
It is preferred that the width of the buttocks supporting patch 8 is gradually increased from a range of 4 to 7 cm on the back center line 7 as shown in
If the width of the buttocks supporting patch 8 is wider, a higher supporting effect can be obtained. However, if a buttocks supporting patch 8 with a certain width of 10 cm or more is sewn to the region ranging from the back body to the front body, about one third of the buttocks are tightened by the buttocks supporting patch, and the roundness of the buttocks is liable to be disfigured. On the contrary, if a buttocks supporting patch 8 with a certain narrow width of less than 4 cm is sewn to the region ranging from the back body to the front ends on the front body, it fits narrow portions such as the gluteal fold, but it does not have a sufficient power to support a wide area including the wearer's sides and abdomen. Therefore, it is preferred that the buttocks supporting patch 8 is gradually increased in width from a range of 4 to 7 cm at the gluteal fold to a range of 5 to 10 cm at the front ends on the front body. With this constitution, without affecting the silhouette viewed from outside, the necessary portions can be tightened with a required minimum power to exhibit the intended buttocks supporting effect.
Further, for keeping the belt-like buttocks supporting patch 8 inclined obliquely upward from below the hipline of the back body toward the front body, it is preferred that the patch is inclined not like straight lines but like curves swelling downward as shown in
On the other hand, in the third embodiment of the pants of this invention, as shown in
The lining fabric 3 covers the region ranging from the buttock portion of the back body 2 through the sidelines 4 to partial portions of the front body 1, and it is preferred to attach a belt-like buttocks supporting patch 8 as in the first and second embodiments of the pants of this invention. Further, as shown in
Further, it is preferred that the width of the belt-like abdomen suppressing patch 16 gradually increases from a range of 8 to 15 cm at the crotch 6 to a range of 12 to 25 cm at the waistline 5. It is not preferred that the width at the waistline 5 is narrower than 12 cm, since the abdomen as a whole cannot be supported. Further, it is not preferred that the width at the waistline 5 is larger than 25 cm for such reasons that the area of the patch 16 overlying on the lining fabric 3 attached to the region ranging from the back body to partial portions of the front body is too large, that the wearing comfort is impaired and that the level difference between the lining fabric 3 and the abdomen suppressing patch 16 can be seen from outside the pants to impair the appearance.
Moreover, it is preferred that the belt-like abdomen suppressing patch 16 is made of the same material as that of the lining fabric 3 and/or the buttocks supporting patch 8. It is not preferred that the abdomen suppressing patch 16 and the lining fabric 3 are different from each other in material for such reasons that the joint at the crotch 6 is liable to break since they are different in material properties such as extension rate, extension recovery rate and thickness and that different touches may be felt between the front body and the back body. Further, to enhance the abdomen supporting effect of the abdomen suppressing patch 16, it is preferred that a satin net or a power net is partially or wholly sewn as in the first and second embodiments of the pants of this invention.
In this invention, the buttocks supporting effect can be confirmed as described below. At first, according to instructions, a wearer wears pants and stands beside a measure with graduations for the region from the floor surface to the position of the wearer's waist, and a camera, preferably a digital camera is used to take a photograph from a wearer's side. Then, on a personal computer, the distance from the floor surface to the buttocks vertex is measured. The position of the buttocks vertex varies depending on the material, size and design of the garment fabric of the pants. So, if pants of quite the same material, size and design are used for comparison, the difference in the position of the buttocks vertex based on the presence or absence of the lining fabric 3 can be expressed as a dimensional difference. Of course the same wearer should be used.
Further, if the garment pressures at various regions are measured, the effect can be confirmed. The garment pressure can be measured by the method described later for the examples.
This invention is described below more particularly in reference to examples and comparative examples, but is not limited thereto or thereby. Meanwhile, the following methods were used to evaluate the qualities of the garment fabrics and lining fabrics of pants used in the examples and comparative examples.
(Measuring Methods)
(1) Extension Rate
The extension rate of a garment fabric or a lining fabric was measured according to the strip method of the method A (extension at constant rate) of JIS L 1096 “Test Methods for General Woven Fabrics.”
At first, each three 5 cm×30 cm specimens were obtained in the warp yarns direction and the weft yarns direction. For measurement, a constant rate elongation tensile tester with an automatic recorder was used, and a specimen was clipped and fixed with a distance of 20 cm without looseness and tension, and extended at a stress rate of 20 cm/min to 14.7 N (1.5 kg), to measure the inter-clip distance. The elongation rate LA (%) was obtained from the following formula. The mean value of three specimens was obtained.
Extension rate LA(%)=[(L1−L)/L]×100
L: inter-clip distance (mm)
L1: inter-clip distance after extension to 14.7 N (mm)
(2) Extension Recovery Rate
The extension recovery rate of a garment fabric or a lining fabric was measured according to the strip method of the method A (repeated extension at constant rate) of JIS L 1096 “Test Methods for General Woven Fabrics.”
At first, each three 5 cm×30 cm specimens were obtained in the warp yarns direction and the weft yarns direction. For measurement, a constant rate elongation tensile tester with an automatic recorder was used, and a specimen was clipped and fixed with a distance of 20 cm without looseness and tension. The specimen was extended at a stress rate of 20 cm/min to 80% of the value of the extension rate (the previous item, LA) obtained separately, allowed to stand for 1 minute, returned to the original position at the same rate, and allowed to stand for 3 minutes. This operation was repeated 10 times, and subsequently, the specimen was extended again to a load larger than the initial load at the same rate. A load-extension curve was recorded, and the residual extension was measured from the curve. The extension recovery rate LB (%) was obtained from the following formula. The mean value of three specimens was obtained.
Elongation recovery rate LB(%)=[(Lb1−Lb)/Lb]×100
Lb: Length of the specimen extended to 80% of the extension rate LA on the chart (mm)
Lb1: Length of the specimen corresponding to the residual extension after 10 times of repeated extension on the chart (mm)
(3) Bursting Strength
The bursting strength of a lining fabric was measured according to the method A (Mullen method) of JIS L 1018 “Test Methods for Knitted Fabrics.”
At first, five 15 cm×15 cm specimens were obtained. A specimen with its right side turned upward was installed at the clip of a Mullen burst tester in an ordinary state without applying tension. A pressure fluid was increased at a rate of 98±4 cm3/min, and at the moment when the rubber film burst through the specimen, the pressurization was stopped to read the pressure at that moment. In succession, the clip was loosened and the specimen was removed, when the pressure of the rubber film indicated by the needle was read. The bursting strength was calculated from the following formula. The mean value of five specimens was obtained.
Bursting strength(kPa)=a−b
a: Pressure at the moment when the rubber film burst through the specimen
b: Pressure of the rubber film after removing the specimen
(4) Position of the Buttocks Vertex
As described before in this specification, the pants worn were photographed by a camera from a wearer's side, and the distance from the floor surface to the buttocks vertex was measured on a personal computer. Wearing, photographing and measurement were performed three times, and the mean value was obtained. Since the vertex could vary depending on the material, size and design of pants, pants with quite the same material, size and design were worn for comparison, to express the difference in the position of buttocks vertex based on the presence or absence of the lining fabric as a dimensional difference. Always the same wearer was used.
Meanwhile, with regard to the buttocks vertex, an auxiliary line was drawn on the image of the wearer's side from a height corresponding to the top of the head to the floor surface vertically, and the intersection at the buttocks was obtained as the buttocks vertex.
(5) Measurement of Garment Pressure
Air pack sensors as contact pressure measuring devices produced by K.K. AMI were stuck to the buttocks vertex, gluteal fold (border between buttocks and thighs) and a side of the wearer, three places in total. The wearer wore pants, stayed stationary for 30 seconds and bent her body forward for 30 minutes, to measure the changing garment pressures. The garment pressure, measurement was performed three times, and the mean value was obtained. Since the value could vary depending on the material, size and design of pants, the same wearer wore pants with the same material, size and design, to obtain the difference of the garment pressures (kPa) based on the presence or absence of the lining fabric. At the respective places of measurement, each garment pressure was evaluated in reference to the three-step criterion shown in Table 1.
(6) Evaluation of Such States as Aesthetic Quality, Wearing Comfort and Skin Touch
Monitors wore produced pants and sensory-evaluated aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect, and abdomen suppressing effect. The evaluation criteria are shown in Table 1.
Ten female monitors of 20s to 50s in age were instructed to wear, and the mean value was obtained for each of the evaluation items. The sum of the mean values of respective evaluation items was obtained as the overall evaluation. A larger overall evaluation value means more excellent evaluation.
Two-plied cotton yarns of yarn count 60 were used as warp yarns and PPT yarns of 165 decitexes were used as weft yarns, to form a 2/1 twill weave, and it was dyed. The woven fabric obtained like this had an extension rate of 8% in the warp yarns direction, an extension rate of 25% in the weft yarns direction, an extension recovery rate of 92% in the warp yarns direction and an expansion recovery rate of 85% in the weft yarns direction. This woven fabric was used as the garment fabric. Further, yarns obtained by covering polyurethane fibers with nylon were knitted using a Raschel machine, to obtain a 6-course satin net. It was used as the lining fabric. The lining fabric had an extension rate of 147% in the warp yarns direction, an extension rate of 41% in the weft yarns direction, an extension recovery rate of 96% in the warp yarns direction, an extension recovery rate of 85% in the weft yarns direction, and a bursting strength of 240 kPa. The garment fabric and the lining fabric were sewn together in the following process, to obtain the lady's pants shown in
At first, the lining fabric was cut to have a form of inclining obliquely upward from the back body to the waistline of the front body. Further, a curved belt-like buttocks supporting patch adapted to the shape of buttocks gradually increasing in width from 5 cm at the back center line to 8 cm at the waistline of the front body was sewn to one side of the lining fabric by a lockstitch zigzag sewing machine, using a nylon wooly yarn as the bobbin thread, lest the extension should be prevented. The buttocks supporting patch used was a power net having an extension rate of 156% in the warp yarns direction, an extension rate of 53% in the weft yarns direction, an extension recovery rate of 96% in the warp yarns direction, an extension recovery rate of 94% in the weft yarns direction and a bursting strength of 290 kPa. The lining fabric having said buttocks supporting patch sewn to it was sewn to the garment fabric sewn in the form of pants at the crotch and the waistline in such a manner that the buttocks supporting patch was kept in contact with the garment fabric.
The sewing specifications of the lady's pants are shown in Table 2, and the results of evaluating the aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and abdomen suppressing effect of the pants as they were worn are shown in Table 3.
Two-plied cotton yarns of yarn count 50 were used as warp yarns and yarns obtained by covering elastic yarns of 44 decitexes with a cotton yarn of yarn count 50 respectively were used as weft yarns, to form a plain weave, and it was dyed. The woven fabric obtained like this had an extension rate of 12% in the warp yarns direction, an extension rate of 28% in the weft yarns direction, an extension recovery rate of 85% in the warp yarns direction and an expansion recovery rate of 65% in the weft yarns direction. This woven fabric was used as the garment fabric. The same satin net as used in Example 1 was used as the lining fabric, and the garment fabric and the lining fabric were sewn together in the following process, to obtain the man's pants shown in
At first, a sleek fabric with an extension rate of 3% in both the machine and weft yarns directions was used as the pocket patches of the pants. They were sewn and seamed to the wrong side c of the garment fabric sewn in the form of pants in the regions ranging from the sidelines to the placket front. Then, the lining fabric was cut in the form of inclining obliquely upward from the back body toward the waistline of the front body, and a buttocks supporting patch formed of the same power net as used in Example 1 was sewn to one side of the lining fabric, to have the form of inclining obliquely upward from below the hipline toward the front body. The buttocks supporting patch was a curved belt gradually increasing in width from 7 cm at the back center line to 10 cm at the left and right front ends. It was sewn to the lining fabric by a lockstitch zigzag sewing machine, using a nylon wooly yarn as the bobbin thread lest the extension should be prevented. The lining fabric having the buttocks supporting patch sewn to it was sewn to the garment fabric at the crotch and the waistline in such a manner that the buttocks supporting patch was kept in contact with the garment fabric and further overlaid on the pocket patches by 15 cm each.
The sewing specifications of the man's pants obtained as described above are shown in Table 2, and the results of evaluating the aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and abdomen suppressing effect of the pants as they were worn are shown in Table 3.
Mixed yarns consisting of polyethylene terephthalate and rayon were used as warp yarns and yarns obtained by covering elastic yarns of 44 decitexes with a mixed yarn consisting of polyethylene terephthalate and rayon respectively were used as weft yarns, to form a 3/1 satin weave, and it was dyed. The woven fabric was used as the garment fabric, to produce the lady's pants shown in
The sewing specifications of the lady's pants obtained as described are shown in Table 2, and the results of evaluating the aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and abdomen suppressing effect of the pants as they were worn are shown in Table 3.
A two-plied cotton yarn of yarn count 50 as a warp yarn and a yarn obtained by covering an elastic yarn of 44 decitexes with a cotton yarn of yarn count 50 as a weft yarn were alternately used for being knitted by a 22 G interlock circular knitting machine. The interlock tubular knitted fabric was dyed according to the dyeing method for ordinary tubular knitted fabrics. The knitted fabric obtained as described above had an extension rate of 60% in the warp yarns direction and an extension rate of 105% in the weft yarns direction, an extension recovery rate of 65% in the warp yarns direction and an extension recovery rate of 75% in the weft yarns direction. The knitted fabric was used as the garment fabric. A lining fabric was sewn to the garment fabric according to the following process, to produce the lady's pants shown in
At first, the lining fabric used in Example 3 was cut to have the form of inclining obliquely upward from the back body to the waistline of the front body. Further, a buttocks supporting patch was sewn to one side of the lining fabric using a two-needle flatlock machine, using nylon wooly yarns as wrong side fancy yarns, lest the extension should be prevented. The buttocks supporting patch was the same power net as used in Example 3, which was a curved belt gradually increasing in width from 7 cm at the back center line to 9 cm at the waistline of the front body. The lining fabric having the buttocks supporting patch sewn to it was sewn to the garment fabric at the crotch and the waistline in such a manner that the buttocks supporting patch was kept in contact with the garment fabric.
The sewing specifications of the lady's pants obtained as described above are shown in Table 2, and the results of evaluating the aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and abdomen suppressing effect of the pants as they were worn are shown in Table 3.
The woven fabric used in Example 4 was used as the garment fabric, and a 2 cm wide flat rubber was inserted into the waist portion, to product the lady's pants without front opening as shown in
The lady's pants obtained as described above were high in aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and the effect of tightening the region ranging from the abdomen to the sides.
The woven fabric used in Example 1 was used as the garment fabric, to produce the same lady's pants as those of Example 1 by sewing. However, neither the lining fabric nor the buttocks supporting patch was attached.
The sewing specifications of the lady's pants obtained as described above are shown in Table 2, and the results of evaluating the aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and abdomen suppressing effect of the pants as they were worn are shown in Table 3.
Spun cotton yarns of yarn count 30 were used as warp yarns and weft yarns, to form a 3/1 satin weave, and it was dyed. The woven fabric was used as the garment fabric, to produce man's pants by sewing. The woven fabric had an extension rate of 5% in the warp yarns direction, an extension rate of 6% in the weft yarns direction, an extension recovery rate of 98% in the warp yarns direction and an extension recovery rate of 98% in the weft yarns direction. The same fabric as the garment fabric was used as the pocket patches, and the front ends of the pocket patches were not sewn to the placket front. A tricot knitted fabric having an extension rate of 99% in the warp yarns direction, an extension rate of 72% in the weft yarns direction, an extension recovery rate of 67% in the warp yarns direction and an extension recovery rate of 73% in the weft yarns direction was sued as the lining fabric. The lining fabric was cut to have the form covering only the buttocks of the back body, and it was sewn to the garment fabric at the crotch and the sidelines. Further, a 20 cm belt-like buttocks supporting patch was sewed to the lining fabric below the hipline by a lockstitch zigzag sewing machine, using a nylon wooly yarn as the bobbin thread, lest the extension should be prevented. Meanwhile, a power net having an extension rate of 156% in the warp yarns direction, an extension rate of 53% in the weft yarns direction, an extension recovery rate of 96% in the warp yarns direction and an extension recovery rate of 94% in the weft yarns direction was used as the buttocks supporting patch.
The sewing specifications of the man's pants obtained as described above are shown in Table 2, and the results of evaluating the aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and abdomen suppressing effect of the pants as they were worn are shown in Table 3.
Long fiber yarns of 100% polyethylene terephthalate yarns of 56 decitexes were knitted by a 20 G circular knitting machine, and the knitted fabric was dyed as usual. The knitted fabric obtained as described above had an extension rate of 40% in the warp yarns direction, an extension rate of 80% in the weft yarns direction, an extension recovery rate of 88% in the warp yarns direction and an extension recovery rate of 55% in the weft yarns direction. The knitted fabric was used as the garment fabric, to produce pants as jersey pants without opening with a rubber inserted in the waist portion. A power net with an extension rate of 109% in the warp yarns direction, an extension rate of 85% in the weft yarns direction, an extension recovery rate of 97% in the warp yarns direction and an extension recovery rate of 87% in the weft yarns direction was used as the lining fabric. It was sewn to cover the back body and the front body in the region above the crotch like a girdle, and sewn to the garment fabric at the waist rubber portion.
The sewing specifications of the lady's pants obtained as described above are shown in Table 2, and the results of evaluating the aesthetic quality, wearing comfort, motion allowance, buttocks supporting effect and abdomen suppressing effect of the pants as they were worn are shown in Table 3.
The pants of this invention look like ordinary pants and can be used as pants with a buttocks supporting effect and excellent wearing comfort. They can also be used as pants with an abdomen shaping effect in addition to the buttocks supporting effect.
