Elastic swim crepe

Abstract

This utility model discloses an elastic swim crepe, which is woven from warp and weft yarns. Both the warp and weft yarns include mulberry silk or mulberry silk covered with spandex. The basic structure of the elastic swim crepe consists of at least 304 warp yarns and 160 weft yarns interwoven, forming a yarn arrangement cycle unit. This basic structure is a plain weave. The fact that both the warp and weft yarns of this utility model include mulberry silk or mulberry silk covered with spandex, using these two types of yarns in a simple plain weave structure, allows the finished fabric to have four-way elasticity and form a bubble-like raised pleated texture. This reduces the workload for weavers, increases output, and lowers production costs.

Description

Technical Field

[0001] This utility model relates to the field of fabrics, specifically to an elastic swim crepe. Background Technology

[0002] Silk fabric is loved for its skin-friendly, soft, breathable, and comfortable properties. With the continuous improvement of people's living standards and the rapid development of the modern garment industry, the application range of silk fabric is becoming increasingly wide. The main characteristics of silk fabric are its lightness, thinness, wrinkleability, and lack of elasticity. Due to its lack of elasticity, allowance needs to be added during the fabric's use. However, each piece of fabric has a different shrinkage rate due to its different weave structure. Tailors cannot perfectly control the allowance during garment making. Too little allowance will cause the finished garment to shrink after washing, resulting in discomfort; too much allowance will result in a loose, unfitting garment, affecting its shape. Furthermore, the lack of elasticity in silk fabric can cause tightness during wear, leading to discomfort and potential damage to the garment.

[0003] Although existing weaving processes can make fabrics elastic through different weave structures, this requires relatively complex weave structures, which is troublesome, increases the difficulty of the weaving workers' work, reduces output, and increases production costs. Summary of the Invention

[0004] To solve the above problems, this utility model provides an elastic swim crepe.

[0005] The technical solution of this utility model is: an elastic swim crepe, which is made of interwoven warp and weft yarns, wherein both the warp and weft yarns include mulberry silk and mulberry silk covered with spandex yarn. The basic structure of the elastic swim crepe is made of at least 304 warp yarns and 160 weft yarns interwoven, and the 304 warp yarns and 160 weft yarns form a yarn arrangement structure cycle unit. The basic structure is a plain weave.

[0006] Preferably, the warp yarns are type A twisted yarn and type B covered yarn, and the weft yarns include type A twisted yarn and type B twisted yarn. The two types of yarns are arranged alternately in the warp direction and also alternately in the weft direction.

[0007] As a further preferred option, the warp arrangement sequence of the elastic swim crepe, that is, the warp arrangement sequence within each yarn arrangement cycle unit, is: 76A+4B+(20A+4B)×2+76A+8B+(20A+4B)×2+36A+8B, for a total of 304 yarns / cycle, wherein each cycle contains 268 yarns of type A twist and 36 yarns of type B twist.

[0008] As a further preferred option, the shuttle insertion sequence of the elastic crepe, that is, the weft yarn arrangement sequence within each yarn arrangement cycle unit, is: 55A + 3B + 13A + 3B + 55A + 3B + 25A + 3B, for a total of 160 yarns / cycle, wherein each cycle contains 148 yarns of type A twist and 12 yarns of type B twist.

[0009] As a further preferred option, type A twisted yarn is made by twisting two strands of type C untwisted yarn, with an S-twist and medium twist; type B twisted yarn is made by covering two strands of type C untwisted yarn (type D untwisted yarn) with one strand of type E spandex, with an S-twist and medium twist.

[0010] As a further preferred option, the specification of type C untwisted yarn is 20 / 22D factory yarn, that is, untwisted factory yarn with a thickness of 20 / 22D.

[0011] As a further preferred embodiment, the E type of spandex has a single strand specification of 30D and is untwisted.

[0012] Preferably, each yarn arrangement cycle unit of the elastic swim crepe includes 304 weft structures with 80 up and 80 down sections. The warp weft point on the odd-numbered warp yarn is the odd-numbered warp weft point at the bottom and the even-numbered warp weft point at the top. The warp weft point on the even-numbered warp yarn is the odd-numbered warp weft point at the top and the even-numbered warp weft point at the bottom.

[0013] The beneficial effects of this utility model are as follows: The warp and weft yarns of this utility model both include mulberry silk and mulberry silk covered with spandex yarn. Using these two types of yarn to manufacture the fabric, with the simplest plain weave structure, the finished fabric can produce four-way elasticity and form bubble-like raised pleated texture, which reduces the difficulty of weaving workers, increases output, and reduces production costs.

[0014] Furthermore, the raw materials used in the production of this utility model consist mostly of mulberry silk, with only a small portion of spandex. This does not affect the fabric's skin-friendliness and breathability at all, allowing the fabric to retain the skin-friendliness and breathability of mulberry silk while possessing high elasticity characteristics that mulberry silk does not have.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown, an elastic swim crepe is made of interwoven warp and weft yarns, both of which include mulberry silk and mulberry silk covered with spandex yarn. The basic structure of the elastic swim crepe consists of at least 304 warp yarns and 160 weft yarns interwoven, and the 304 warp yarns and 160 weft yarns form a yarn arrangement cycle unit. The basic structure is a plain weave.

[0020] In this embodiment, the warp yarns are type A twisted yarn and type B covered yarn, and the weft yarns include type A twisted yarn and type B twisted yarn. The two types of yarns are arranged alternately in the warp direction and also alternately in the weft direction.

[0021] In this embodiment, the warp arrangement sequence of the elastic swim crepe, that is, the warp arrangement sequence in each yarn arrangement cycle unit, is: 76A+4B+(20A+4B)×2+76A+8B+(20A+4B)×2+36A+8B, a total of 304 yarns / cycle, wherein each cycle contains 268 yarns of type A twist and 36 yarns of type B twist.

[0022] In this embodiment, the shuttle insertion sequence of the elastic crepe, that is, the weft yarn arrangement sequence in each yarn arrangement cycle unit, is: 55A + 3B + 13A + 3B + 55A + 3B + 25A + 3B, for a total of 160 yarns / cycle, wherein each cycle contains 148 yarns of type A twist and 12 yarns of type B twist.

[0023] In this embodiment, type A twisted yarn is formed by twisting two strands of type C untwisted yarn, with an S-twist direction and medium twist, preferably with a twist of 13-16T; type B twisted yarn is formed by covering two strands of type C untwisted yarn with type D untwisted yarn and one strand of type E spandex, with an S-twist direction and medium twist, preferably with a twist of 15-20T.

[0024] In this embodiment, the specification of the C type untwisted yarn is 20 / 22D factory yarn, that is, untwisted factory yarn with a thickness of 20 / 22D.

[0025] In this embodiment, the single strand specification of the E type of spandex is 30D, and it is untwisted.

[0026] In this embodiment, each yarn arrangement cycle unit of the elastic crepe includes 304 weft structures with 80 up and 80 down weft structures. The warp weft point on the odd-numbered warp yarn is the odd-numbered warp weft point at the bottom and the even-numbered warp weft point at the top. The warp weft point on the even-numbered warp yarn is the odd-numbered warp weft point at the top and the even-numbered warp weft point at the bottom.

[0027] Twist between 1-8T is considered low twist, between 8T and 20T is medium twist, and above 20T is high twist. Higher twist results in a tighter, more drapey, and stronger fabric. Raw silk has a sheen when untwisted, but becomes matte after twisting. Low-twist yarns have a better sheen than high-twist yarns. In this embodiment, two strands of untwisted C-type yarn are combined with a medium-twist yarn to form type A twisted yarn. This yarn has a moderate sheen, without excessive luster or high curl. Type B twisted yarn is a covered yarn composed of two strands of untwisted C-type yarn (type D-type) and one strand of spandex (type E-type). This gives the originally inelastic mulberry silk high elasticity. The arrangement of type A and type B twisted yarns creates a bubble-like, wrinkled texture, retaining the skin-friendly and breathable properties of mulberry silk while also providing good elasticity.

[0028] The fabric is produced using a relatively simple eight-piece hemp weave method and a plain weave structure. Two types of yarns are used for both the warp and weft, and the fabric is woven on a rapier loom. This reduces the complexity of hemp weaving for textile workers and allows for largely automated production after hemp weaving. The production process is more convenient, the production quality is guaranteed, and the production efficiency is high.
