Problems solved by technology

[0003] For example, in China's published patent CN200810244019.5, it is proposed that in order to make the fabric have a cowboy style while ensuring its elasticity and soft feel, the warp yarn is made of pure cotton fiber, and the weft yarn is made of elastic composite fiber and pure cotton fiber coated with spandex fiber to form a composite fiber; For example, in Chinese patent CN200620071965.0, in order to improve the fading and non-wearing problems of pure cotton denim cotton, polyester superfine sea-island silk and easy-colored cotton yarn are interwoven with warp and weft. A large number of cotton yarns are used in the fabrics involved in the above two patents, while Cotton is dark in color and easy to fade, has poor shape retention after washing, and is not wear-resistant, so its fading and wear-resistant problems have not been completely solved, and the elasticity and moisture absorption and quick-drying performance of the fabric are not good, so the wearing comfort is not good

Abstract

The invention discloses a jeans elastic fabric and a method for producing the same, wherein the warp of the fabric at least contains 20wt% of cationic dyeable thick-and-thin polyethylene terephthalate (PET) yarns, the weft at least contains 20wt% of elastomeric yarns, during the after finishing process, the obtained fabric has good elasticity, soft handfeel, excellent wear resistance and difficulty in color fading through alkali reduction treatment and cationic dyeing, the water absorption of the fabric is below 1.5s, the elasticity is between 5% and 30%, and the elasticity recovery is above 80%.

Description

technical field [0001] The invention relates to a textile fabric, in particular to a denim-style elastic fabric and a production method thereof. Background technique [0002] At present, the raw materials of denim fabrics on the market are generally synthetic fibers, natural fibers and recycled fibers. Among them, synthetic fibers occupy a large proportion in the entire fabric market. The synthetic fibers used to weave denim fabrics are mainly polyester and nylon. Polyester denim fabrics have high brightness, good luster, and bright colors, breaking through the traditional single color and dull style of denim fabrics, and injecting new vitality into the denim family. [0003] For example, in China's published patent CN200810244019.5, it is proposed that in order to make the fabric have a cowboy style while ensuring its elasticity and soft feel, the warp yarn is made of pure cotton fiber, and the weft yarn is made of elastic composite fiber and pure cotton fiber coated with ...
