Manufacturing method of elastic fabric

Abstract

The invention relates to a manufacturing method of an elastic fabric. A double-elastomer core-spun yarn structure is used, spandex and nylon 6 or nylon 66 fiber are fused into a single fabric, and high stretchability of the spandex and excellent resilient force of the nylon 6 or nylon 66 fiber can be achieved by different shrinkage ratios of the two fibers. The elastic fabric can retain the advantages, such as high elasticity and high resilience, of two-component fiber fabrics, cotton fiber, the spandex and the nylon 6 or nylon 66 fiber are used in part of the fiber system in terms of materialcomposition, so that the appearance of the elastic fabric cannot have the white dot defect or unfinished areas due to the fact that nylon fiber can be contaminated and colored after yarn dyeing, andthe elastic fabric can be used for lightweight clothing. Therefore, the woven elastic fabric, such as a woven fabric and a knitted fabric, has high elasticity and high resilience, and can be applied to the lightweight cloth which touches soft, is fit, durable, good in elastic resilience, difficult to deform and has no unfinished areas.

Description

technical field [0001] The invention relates to a manufacturing method of an elastic fabric, especially 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, and elastic recovery It is a lightweight fabric with good strength, which is not easy to deform and has no whitening phenomenon. Background technique [0002] 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 (the product name in the United States and Canada is Spandex), and the industry in Taiwan, China is usually called OP. [0003] Polyurethane elastic fibers are generally not used alone, but mixed into fabrics in small...

Problems solved by technology

[0004] Although polyurethane elastic yarn has excellent elastic elongation and recovery, it is more comfortable to wear, but there are still some shortcomings, such as high sensitivity to weaving and dyeing and finishing, improper process can easily cause weft or OP breakage, poor alkali resistance It is not suitable for weight reduction processing, and its thermal dimensional stability is poor. When it is interwoven with polyester fiber, it cannot be colored due to polyurethane, which may easily cause grin through or poor color fastness, etc.

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

[0005] To reduce whitening, it is necessary to dye the fabric in two separate dyeing steps, however this is a costly and lengthy process

Also, it is difficult to match the color of the sheath staple fiber to the color of the bicomponent filament core

Therefore, it generally cannot meet the needs of users in actual use.
