Problems solved by technology

For example, Chinese patent 200510114739.6 discloses a kind of polar fleece textile and its production method using polyester hollow fiber as raw material, specifically adopting the hollow yarn of polyethylene terephthalate with a hollowness of 18 to 30% and / or filament as raw material to form polar fleece textiles, although its light weight and warmth retention are guaranteed, but the elasticity is not enough
[0006] In addition, if the fully drawn yarn (FDY) with a certain hollowness is directly used for weaving, although the hollowness of the fiber can be well maintained, such a product feels hard; and in order to improve the handfeel, the hollow FDY is fake If it is used after twisting, the hollowness of the yarn will be destroyed during false twisting, which will affect the warmth retention of the final product

Abstract

The invention discloses a fabric containing hollow fiber and a production method thereof. The fabric containing hollow fiber is a knitted fabric formed by at least hollow cation dyeable false twisted yarn or staple fiber yarn and spandex fiber. Tested according to the JISL1096:2010 standard, the fabric obtains a filling power more than 4.0 cm3 / g and a gram weight higher than 150-250 g / m2; the hollow area of more than 80% of the filaments of the hollow cation dyeable false twisted yarn or staple fiber yarn is 50-150 mm2. Knitted from the hollow cation dyeable false twisted yarn or staple fiber yarn with restorable degree of hollowness, the fabric containing the hollow fiber ensures the elasticity, light weight and soft hand feeling.

Description

technical field [0001] The invention relates to a textile, in particular to a hollow fiber-containing fabric with a lightweight, fluffy and warm-keeping function. Background technique [0002] In a modern society where living standards are improving day by day, people's requirements for clothing, especially winter clothing, are no longer at the stage of keeping warm from the cold, and they are more required to have both thermal insulation and light weight. Among them, polar fleece and brushed wool products are deeply loved by consumers for their unique feel and warmth retention. [0003] In the past, the raised fabrics were generally polyester or cotton-polyester interwoven raised fabrics, which were much heavier than ordinary fabrics and had a bad hand feeling; when spandex and spandex composite yarns were interwoven with polyester or cotton-polyester, the thickness The weight will be greater, the cost is also very expensive, and the sense of thickness is too obvious, and ...
