A kind of high-count spun yarn warp knitted fabric and its preparation method

Abstract

The invention provides a high-count short-fiber warp-knitted fabric and a preparation method thereof. In the preparation process, the invention changes the traditional porcelain pillars and porcelain eyelets into light-weight Teflon guide wheels through the improvement of the tensioner to effectively ensure flexibility. Warping to achieve the production goal of ultra-low strength loss. Through the airbag tension system, the problem of insufficient elastic recovery of high-count spun yarns is solved. Through the segmented sequential opening vacuum system, there is no excessive accumulation and floating of flying flowers on the production site. The invention solves the mature application of high-count spun yarn in warp knitting, narrows the gap between this industry and developed countries in spun-fiber warp knitting technology, and at the same time, this technology can also feed back the existing medium and low-count staple-fiber warp knitting technology. Knitting production, making its production more stable and more likely to be routinely mass-produced, provides a systematic basic attempt and research for the industry to launch new staple warp knitting attempts on a large scale. The fabrics of the present invention have the characteristics of high count, high density, and high elasticity, with obvious product characteristics, stable quality, unique style, and high market value.

Description

technical field [0001] The invention relates to the field of warp-knitted fabrics, in particular to a high-count spun yarn warp-knitted fabric and a preparation method thereof. Background technique [0002] In the textile field, it is generally considered that the yarn above 50Ne is a high-count yarn. Spinning and application of high-count yarns have become common. Fabrics produced with high-count yarns have a fine, soft, and flat appearance, and fabrics with extra-high-count yarns can even produce silk-like luxury and have high wearing comfort. [0003] High-count yarns and extra-high-count yarns have been widely used and promoted in woven fabrics. Domestic factories have been able to produce high-grade poplin cotton shirting fabrics with a warp and weft fineness of 140Ne. The application of weft knitting has already begun. For example, domestic and Japan have launched high-count and high-density weft-knitted cotton knitted fabric shirts. However, the domestic warp knitti...

AI Technical Summary

Problems solved by technology

However, the domestic warp knitting industry has been exploring the application of spun yarn in warp knitting for a long time, and a small number of attempts are mostly limited to the application of medium and low count yarns below 40Ne, but there are few applications for warp knitting of high count yarns. The main reason is that it is limited by many performance problems such as low strength, low elongation, and many flying flowers of high-count yarns.
