Problems solved by technology

[0003] However, since warp knitting products have high requirements on yarn quality, strength and elasticity, and cotton fibers are affected by natural conditions, the output is unstable, so it is difficult to produce corresponding knitted products normally on high-speed warp knitting machines, which is not conducive to application

Abstract

The invention provides a cotton-like full dull warp knitted pile fabric and a production method thereof. The method comprises the following steps of 1) performing heat treatment and twisting on full dull polyester and polyester blended yarns, and obtaining full dull polyester cotton-like yarns, wherein the full dull polyester and polyester blended yarns are formed by full dull full drawn polyester filament yarns and full dull pre-oriented polyester filament yarns; and 2) performing high-speed warp knitting after the full dull polyester cotton-like yarns are warped, and obtaining a cotton-like full dull warp knitted pile grey fabric. The novel cotton-like full dull warp knitted pile fabric produced by the method has cotton hand feeling and polyester high-strength and wear resistance, and has the characteristics of stable dimension, moderate elasticity and high anti-run capability of a warp knitted fabric. The cotton-like full dull warp knitted pile fabric accords with the current fabric fashion trend, and can be widely used in the field of clothes and home textiles. In addition, the produced polyester cotton-like filament yarn knitted warp knitted production can solve the problem that the warp knitted cotton fabric cannot be produced in a high speed, and can also relieve the production stress caused by indetermination of cotton price.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a cotton-like full-dull warp-knitted fabric and a production method thereof. Background technique [0002] As social needs change, people's demand for high-end clothing and home textiles is increasing. Full-dull polyester fabric has the advantages of soft hand feeling, soft luster, bright color, good drapability and low cost, and its fabric is very popular among people. At the same time, modern people prefer cotton fabrics, which are more friendly to the skin, and the colors are softer and less dazzling than ordinary polyester fabrics. Cotton knitwear is deeply loved by consumers for its good hygroscopicity, softness and comfort. [0003] However, since warp knitting products have high requirements on yarn quality, strength and elasticity, and cotton fibers are affected by natural conditions, the output is unstable. It is difficult to produce corresponding knitted produ...
