Description

Dual-elastomer core-spun yarn structure and woven elastic fabric

technical field

The utility model relates to a double-elastomer core-spun yarn structure, and at the same time relates to an elastic fabric woven with a double-elastomer core-spun yarn structure, which has high elasticity and high recovery, and can be used for soft hand feeling, long-lasting fit, Lightweight fabric with good elastic recovery, not easy to change shape and no whitening phenomenon.

Background technique

The elastic yarns commonly used in the market can be roughly divided into two categories: polyurethane elastic yarn (Lycra or Spandex) and polyester mechanical elastic yarn. Among them, polyurethane elastic fiber is a kind of artificial elastic yarn successfully developed by DuPont in 1959. The registered trademark is Lycra-Lycra (in the United States and Canada, the product name is Spandex); the Chinese Taiwan industry is usually called OP.

Polyurethane elastic fibers are generally not used alone, but mixed into fabrics in small amounts. It usually has four main forms, including: bare silk; covered yarn, single-layer covered (Single Covered Yarn, SCY) and double-layer covered (Double Covered Yarn, DCY); air interlaced yarn (Air-Jet Covered Yarn, ACY); and Core Spun Yarn (CORE SPUNYARN). The above-mentioned bare silk is usually used for knitted textiles, while covered yarn and air interlaced yarn are mostly used for silk weaving. Core spun yarn is coated by spun yarn on worsted spinning machine, and is generally used for denim.

Although polyurethane elastic yarn has excellent elastic elongation and recovery, which can make it more comfortable to wear, it still has some disadvantages, such as high sensitivity to weaving and dyeing and finishing, improper workmanship may easily cause weft or OP breakage, and wear resistance. Poor alkalinity is not suitable for reduction processing. In addition, the thermal dimensional stability of the fabric is poor, and polyurethane cannot be colored when interwoven with polyester fibers, which may easily cause grin through or poor color fastness. These are also disadvantages. For example, Invista (Invista) once launched a core-spun elastic yarn product of Lycra®T400® polyester bicomponent fiber. The yarn count is generally lower than Ne20's, with high elasticity and high recovery, and is mostly used for heavy jeans. , but its composition of cotton plus polyester plus Lycra is prone to uneven dyeing and 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 this is a costly and tedious process. Additionally, it has been difficult to match the color of the sheath staple fibers to the color of the bicomponent filament core. Therefore, it generally cannot meet the needs of users in actual use.

The draft ratio of the yarn elastic body is 2.0-3.6.

The outer fiber layer is cotton, wool or a combination thereof.

The yarn count of the core-spun yarn is Ne5-Ne90.

The utility model also provides an elastic fabric, which is formed by directly interweaving warp yarns and weft yarns. Elastic body and outer covering fiber layer, the yarn elastic body is a core yarn made of any one of nylon 6 fiber or nylon 66 fiber and elastic fiber; the outer covering fiber layer is along the axial direction of the yarn elastic body in the The yarn elastic body is the center and wraps around the yarn elastic body.

The elastic fabric is woven or knitted or a combination of woven and knitted.

The elastic fabrics include lightweight garments. The light-weight clothing includes tops and trousers.

The elastic fabric is free of white yarn elastomers.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , which are respectively a three-dimensional schematic view of the structure of a dual-elastomer core-spun yarn according to an embodiment of the present invention, and a schematic view of a partial structure of an elastic fabric according to an embodiment of the present invention. As shown in the figure: the utility model is a dual-elastomer core-spun yarn structure, and its yarn count ranges from Ne5 to Ne90, preferably Ne30 to Ne90. The structure includes yarn elastic body 1 and outer fiber layer 2. constitute.

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 its draft ratio is 2.0-3.6. Wherein the first elastic body 11 is one of nylon 6 fiber or nylon 66 fiber, with a denier number of 10D-70D, and the second elastic body 12 is elastic fiber (Spandex), with a denier number of 10D-70D .
