Double elastomer core-spun yarn structure and elastic fabric

The present invention relates to a double-elastic core-spun yarn structure and an elastic fabric thereof, and more particularly to an elastic fabric woven by a double-elastic core-spun yarn structure, in particular, having high elasticity and high recovery, and can be used for Lightweight hand, long-lasting, elastic recovery, and not easy to change or light white clothing.

Currently, the elastic yarns commonly used in the market can be roughly classified into two types: polyurethane elastic yarns (Lycra or Spandex) and polyester mechanical elastic yarns. Among them, polyurethane elastic fiber is a kind of artificial elastic yarn developed by DuPont in 1959. The registered trademark is Lycra-Lycra (in the US and Canada under the trade name Spandex); the Taiwanese industry is usually called OP.

Polyurethane elastic fibers are generally not used alone, but are incorporated into the fabric in small amounts. It usually has four main forms, including: bare wire; covered yarn, single cover coated (SCY) and double cover (Double Covered Yarn, DCY); air-Jet Covered Yarn, ACY); and core yarn (CORE SPUN YARN). The above-mentioned bare wires are generally used for knitting textiles, while the covered yarns and air entangled yarns are used for more weaving. The core spun yarn is a spun yarn that is coated in a fine spinning machine and is generally used for denim.

Although the polyurethane elastic yarn has excellent elastic elongation and recovery, it can be worn more comfortable, but there are still some disadvantages. For example, the susceptibility to weaving and dyeing and finishing is high, and the improper process may cause the weft or OP to break, the alkali resistance is not suitable for the reduction processing, and the thermal stability of the fabric is poor, and the polyurethane cannot be colored when interlaced with the polyester fiber. It is easy to cause grin through or poor color fastness, which is also a disadvantage. Such as Invista Introducing a core-elastic yarn product of Lycra® T400® polyester bicomponent fiber, the yarn count is generally lower than Ne20's, with high elasticity and high recovery, especially for heavy jeans, but cotton plus polyester plus Lycra The composition is easy to be unevenly dyed and produces white spots, so there is a bad phenomenon of grin through.

To reduce whitening, it is necessary to dye the fabric in two separate dyeing steps, however it is a costly and lengthy method. In addition, it is also difficult to match the color of the outer sheath segment fibers to the color of the bicomponent filament core. Therefore, the general practitioners cannot meet the needs of the user in actual use.

The main purpose of this creation is to overcome the above problems encountered in the prior art and to provide a composite of spandex and nylon 6 or nylon 66 fibers into a single multi-component elastic yarn, which not only retains the two-component fiber fabric. It has the advantages of high elasticity and high recovery, and uses cotton fiber, spandex and nylon 6 or nylon 66 fiber in the material composition, so that the appearance of the elastic fabric after dyeing the yarn, by nylon fiber It will be stained and colored, so that the appearance will not be whiter, and it can have a double-elastic core-spun yarn structure for light-weight fabrics.

The second objective of the present invention is to provide a woven elastic fabric, such as woven fabric (top, trousers), knitted fabric, etc., which has high elasticity and high recovery, and can be used for soft hand feeling and fit.

In the above embodiments of the present creation, the elastic fabric comprises a lightweight garment garment.

In the above embodiment of the present creation, the lightweight garment includes a top and a pant.

In the above embodiments of the present creation, the elastic fabric has no grin through yarn elastic body.

Please refer to FIG. 1 and FIG. 2, which are respectively a perspective view of a double-elastic core-spun yarn structure according to an embodiment of the present invention, and a partial structural view of an elastic fabric according to an embodiment of the present invention. As shown in the figure: the present invention is a double-elastic core-spun yarn structure having a yarn count of Ne5~Ne90, preferably Ne30~Ne90, comprising a yarn elastic body 1 and an outer fiber layer 2. .

The yarn elastic body 1 mentioned above is a core yarn made of the first elastic body 11 and the second elastic body 12, and has a draw ratio of 2.0 to 3.6. The first elastic body 11 is one of nylon 6 or nylon 66 fiber, and has a Danny number of 10D to 70D. The second elastic body 12 is an elastic fiber (Spandex) and has a Danny number of 10D to 70D.

The outer fiber layer 2 is selected from cotton, wool or a combination thereof, and is wrapped around the yarn elastic body 1 around the yarn elastic body 1 in the axial direction of the yarn elastic body 1 . Thus, a novel double elastomer core-spun yarn structure is constructed by the above disclosed structure.

The present work further includes an article comprising an elastic fabric 100 that is substantially free of yarn elastomer 1 grin through, as shown in FIG. In the present embodiment, the elastic fabric 100 is directly interwoven by the warp yarns 111 and the weft yarns 121, wherein at least one of the warp yarns 111 and the weft yarns 121 comprises the above-described double-elastic core-spun yarn structure. In the illustrated embodiment, the above-described bi-elastic core-spun yarn structure is employed as the warp yarn 111, and the material as the weft yarn 121 may be the same as or different from the warp yarn. For purposes of illustration, a mesh structure is shown to demonstrate the manner in which the warp yarns 111 are interwoven with the voiles 121. However, the actual fabric can be woven. For example, the elastic fabric 100 can be integrally processed by woven, knitted or two blending methods. In the case of the cloth, the plain weave is shown in the embodiment, and the warp yarns 111 and the weft yarns 121 are interlaced in an alternating manner. Finally, the elastic fabric 100 is dyed and trimmed by a dyeing method.

Accordingly, this creation mainly uses a double-elastic core-spun yarn structure to fuse elastic fibers (Spandex) and nylon 6 or nylon 66 fibers into a single fabric, and utilizes different shrinkage ratios of the two fibers, thereby enjoying the two fibers. The best advantage is the high stretchability of spandex and the excellent restoring power of nylon 6 or nylon 66 fiber. Specifically, compared with the conventional elastic fabric, the elastic fabric provided by the novel creation not only retains the advantages of the two-component fiber fabric, such as high elasticity and high recovery, but also has a part of the fiber in the material composition. The use of cotton fiber, elastic fiber (Spandex) and nylon 6 or nylon 66 fiber, so that the appearance of the elastic fabric after the dyeing of the yarn, by the nylon fiber will be contaminated and colored, so that the appearance is less white, It can be used for lighter clothing without having a whitening phenomenon. Thereby, the elastic fabric woven by the double-elastic core-spun yarn structure proposed by the present invention, such as woven fabric (top, trousers), knitted fabric, etc., has high elasticity and high recovery, and can be used for Soft touch, long-lasting, elastic recovery, and it is not easy to change or light white fabric.

In summary, the present invention is a double-elastic core-spun yarn structure and an elastic fabric thereof, which can effectively improve various disadvantages of the prior art, and the elastic fabric woven by the double-elastic core-spun yarn structure has high elasticity and high recovery. It can be used on lightweight fabrics with soft hand, long-lasting fit, good elastic recovery, and no change and no whitening, which makes the creation of this creation more progressive, more practical and more suitable for users.
