Patent Application
20200102675
The present invention relates generally to knitted and woven fabrics which may be used in the manufacture of garments.
Elastic materials are commonly used in the construction of garments to improve comfort to the wearer. Garments constructed from such elastic materials may stretch to conform to the body of the wearer when worn, and recover to their relaxed state after removal from the wearer and laundering. However, it would also be desirable for such garments to produce a slimming effect on the wearer, thereby enabling the wearer to present an aesthetically appealing, contoured and shaped body profile.
Accordingly, there is a need for improved fabrics and designs in the manufacturing of garments.
An aspect of the present disclosure relates to new and improved knit fabric for use in the manufacturing of garments. The fabric comprises a first yarn having a first spandex fibre core and a rayon fibre sheath; and a second yarn having a second spandex fibre core and a nylon fibre sheath.
Another aspect of the present disclosure relates to a new and improved garment composed of sewn sections of a knit fabric, said knit fabric comprising: a first yarn having a first spandex fibre core and a rayon fibre sheath; and a second yarn having a second spandex fibre core and a nylon fibre sheath, wherein said rayon fibre sheath comprises rayon having an S number of 40, said nylon fibre sheath comprises nylon having a denier of 70, and each of said first spandex fibre core and said second spandex fibre core comprises spandex having a denier of 40.
In another aspect there is provided a woven fabric comprising: a warp yarn having a first spandex core and a cotton fibre sheath; and a weft yarn having a second spandex core and a blended polyester and rayon fibre sheath.
Other aspects, features, and embodiments of the present disclosure will become apparent to those of ordinary skill in the art upon review of the following description of specific embodiments in conjunction with the accompanying figures.
In the figures, which illustrate, by way of example only, embodiments of the present disclosure:
An embodiment of the present disclosure relates to a fabric that may be used in the manufacturing of garments. The fabric is well-suited for use in the manufacture of pants.
Referring now to the drawings,
As depicted in
The knitting pattern depicted in
Each course C includes two threads of yarn. The fabric 100 is comprised of two types of yarns, a first elastic core-spun yarn having a spandex fibre core and a rayon fibre sheath, and a second elastic core-spun yarn having a spandex fibre core and a nylon fibre sheath. The courses C are arranged such that they alternately include threads of yarn with spandex fibre core and rayon fibre sheath, and threads of yarn with spandex fibre core and nylon fibre sheath. Thus, the threads of yarn in a given course C are of the same composition, but differ in composition from the threads of yarn in the courses directly adjacent to it.
For example, in
The rayon fibre sheath of the yarn comprising threads 102, 104, 110, and 112 may be a Siro compact yarn with an S number of 40. The nylon fibre sheath of the yarn comprising threads 106 and 108 may be 70 denier nylon 66 yarn. The spandex core of the yarns comprising threads 102, 104, 106, 108, 110 and 112 may be 40 denier spandex. The fabric 100 may thus have a rayon content of 68% by weight, a nylon content of 28% by weight, and a spandex content of 4% by weight.
Fabric 100 may be dyed, washed, and finished to make it suitable for use in the construction of garments, and for example, pants. The dying, washing, and finishing processes used to treat fabric 100 are known in the art and so are not further described.
The fabric 100, as constructed in accordance with the present disclosure, can be stretched between 30% to 36% along the weft direction, and 48% to 58% along the warp direction, (i.e. perpendicular to the weft direction) when tested using Standard Test Method ASTM D-2594. The stretchability of finished fabric 100 is not significantly impacted by laundering the fabric. While fabric 100 is stretchable in both the weft and warp directions, it readily recovers to its relaxed state after tensile forces are removed from the fabric.
Turning to
Pants 300 have a left side front panel 316 and a rear panel 318 and a right side front panel 320 and rear panel 322. When the pants are worn, front panel 316 covers the left thigh and front of the left leg of the wearer (not shown), back panel 318 covers the left buttock and rear of the left leg of the wearer, front panel 320 covers the right thigh and front of the right leg of the wearer, and back panel 322 covers the right buttock and rear of the right leg of the user. Each leg may terminate in a cuff 324, 326. The fabric 100 in pants 300 is oriented such that the courses C of fabric 100 run parallel to the waist of pants 300 (i.e. perpendicular to the length dimension, L, of the pants).
As can be appreciated, it would be desirable that pants 300 have a slimming effect on the wearer, thereby enabling the wearer to present an aesthetically appealing, contoured and shaped body profile. It has been surprisingly discovered that pants comprising the knitted fabric depicted in
More specifically, as depicted in
The dimensions of the patterns may vary depending on the style of the pants to be constructed therefrom. For example, the length of the pants may change by varying the inseam length 350 and outseam length 352 of pants 300 to create different styles of pants. Thus, whereas the cuffs 324 and 326 of pants 300 may end at the ankles of the wearer for long pants, the cuffs 324 and 326 of the pants 300 may end just below the knees for culottes, or midway between the knees and ankles of the wearer for capris.
Moreover, the thigh circumference 332, knee circumference 334, calf circumference 336 and leg opening 336 of the pants 300 may be altered to change the silhouette of the pants constructed therefrom.
The aforementioned and other modifications may be made by those skilled in the art to create pants of different sizes and styles. For all such variants of pants 300, the total crotch length when configured to be between seven and twelve inches longer than 47% of the waist circumference provides compressive forces to the body of the wearer to produce a desired slimming effect on the wearer.
When pants 300 are worn, the fabric of pants 300 are in a perpetually stretched condition about the buttocks and upper thighs of the wearer. The pants 300 will thus snugly hug the waist, buttocks, upper hip and lower hip of the wearer such that the pants 300 create a slimming effect on the body of the wearer. Moreover, the elasticity of the fabric of the pants 300 is such that during movement of the wearer, for example, when the wearer sits down or bends over, the pants 300 do not ride up on the legs or into the crotch or intergluteal cleft of the wearer and do not have to be manually adjusted by the wearer. When the pants 300 are removed from the wearer, they will recover to their original relaxed state.
Turning now to
Woven fabric 200 has weft threads 202 and warp threads 204, woven together using a 3/1 twill weave pattern. Each weft thread 202 is a yarn having a spandex core of 70 denier spandex and a cotton fibre sheath of ring spun cotton with an S number of 16. Each warp thread 204 is a yarn having a spandex core of 70 denier spandex and a blended rayon and polyester sheath. Preferably, the rayon and polyester in the blended rayon and polyester sheath are blended together in a ratio of 22:19 rayon to polyester by weight. Further, the polyester of the blended rayon polyester sheath is preferably terylene. The fabric 200 may thus have a cotton content of 55% by weight, a rayon content of 22% by weight, a polyester content of 19% by weight, and a spandex content of 4% by weight.
Fabric 200 may be dyed, washed, and finished to make it suitable for use in the construction of garments. In a preferred finishing method, fabric 200 is first subjected to a desizing washing using water at a temperature of about 28° C. for about 20 minutes, then subjected to enzyme washing using water at a temperature of about 40° C. and cellulase (at a concentration which is selected dependent upon the desired fashion effect) for about 40 minutes, and then finally rinsed and softened.
The finished fabric 200 can be stretched between 50% to 58% along the weft direction, and 20% to 25% along the warp direction, (i.e. perpendicular to the weft direction) when tested using Standard Test Method ASTM D3107. The stretchability of finished fabric 200 is not significantly impacted by laundering the fabric. While fabric 200 is stretchable in both the weft and warp directions, it readily recovers to its relaxed state when tensile forces are removed.
Turning to
Pants 1000 are dimensionally identical to pants 300 of
Given that pants 1000 are dimensionally identical to pants 300, pants 1000 are constructed from the patterns of
The pants 1000 thus constructed snugly hug the waist, buttocks, upper hip, and lower hip of the wearer such that the pants create a slimming effect on the body of the wearer and conform to movements of the wearer. Moreover, the elasticity of the fabric of the pants 1000 is such that during movement of the wearer, such as, for example, when the wearer sits down or bends over, the pants 1000 do not ride up on the legs or into the crotch or intergluteal cleft of the wearer and do not have to be manually adjusted by the wearer.
Other modifications will be apparent to those skilled in the art and, therefore, the invention is defined in the claims.
