Problems solved by technology

However, the adaptability of warp knitting to raw materials is relatively poor, and synthetic fiber filaments with high strength and good elongation are generally used, such as polyester, nylon, spandex, etc.
Because warping is required before warp knitting, and the speed of warp knitting machines is generally high, warp knitting has high requirements for yarn hairiness, tensile breaking strength and elongation, and warp knitting and yarns arranged in parallel during weaving There should not be too much hairiness and flying flowers between, otherwise it will cause yarn entanglement, yarn breakage, etc., which will hinder the smooth progress of weaving and reduce production efficiency
However, spun yarns generally have low strength. During warp knitting, due to the need to withstand the tension fluctuations of the front and back of the guide bar needles during the loop forming process, spun yarns are easy to break; secondly, spun yarns have more hairiness. Yarns are easy to stick together, warping and weaving fly more

Embodiment 1

[0031] A cotton-polyester interwoven warp-knitted fabric, which is composed of the following components: 32s compact spun cotton yarn is 72.3%, 75D / 72F PBT filament is 27.7%, and the warp yarn of the fabric is protruded on the reverse side of the process to form twill floating lines. The twill dimples are formed where the knitting chain is looped, thus forming the twill effect.

[0032] The manufacturing process of described cotton polyester interwoven warp knitted fabric is:

[0033] 1. Preparation process: select 21s~60s compact spinning cotton yarn and 40~75D PBT filament;

[0034] 2. Warping process: temperature and humidity at the warping site: temperature 25±1°C, relative humidity 65±5%, relatively high and stable temperature and humidity are conducive to the stability of twisting and soft surface of cotton yarn, and avoid entanglement with each other , which is beneficial to the production of warp knitted products;

[0035] According to the conventional warping operat...

Abstract

The invention relates to a process for manufacturing a cotton-polyester interwoven warp knitted fabric. The process is characterized by comprising the following steps: (1), selecting materials, namely, selecting cotton yarns and PBT long yarns; (2) performing warping, namely, performing warping on the cotton yarns and the PBT long yarns on a warping machine; (3) weaving, namely, weaving by using a tricot warp knitting machine, wherein the yarn threading mode of a guide bar is that 1 cotton yarn is threaded and one internal is preserved in one GB guide bar, one cotton yarn is threaded and one interval is preserved in 2 GB guide bars, and 4 GB guide bars are fully threaded with the PBT long yarns; or 1 cotton is threaded and 2 intervals are preserved in one GB guide bar, 1 cotton yarn is threaded and 1 internal is preserved in 2 GB guide bars, 2 cotton yarns are threaded and 1 interval is preserved in 3 GB guide bars, and 4 GB guide bars are fully threaded with the PBT long yarns; and (4) performing aftertreatment, namely, performing singeing, scouring and bleaching, dyeing and shaping on a woven blank fabric, and cooling, thereby obtaining the cotton-polyester interwoven warp knitted fabric. The process is simple in process and low in cost, comfort and elasticity are provided for the fabric due to a warp knitted coil structure, and the elasticity resilience is improved.

Description

technical field [0001] The invention relates to a manufacturing process of a cotton-polyester interwoven warp-knitted fabric, in particular to a manufacturing process of a comfortable elastic cotton-polyester interwoven warp-knitted twill fabric, belonging to the technical field of cotton-polyester warp-knitted fabric and its production. Background technique [0002] With the return of people's pursuit of comfort and natural concepts, cotton yarn, as one of the main natural textile materials, is more favored by people because of its softness, moisture absorption, comfort and other advantages. However, at present, cotton yarn is mainly used in weft knitting in knitting. Compared with machine weaving and weft knitting technology, the wearing performance of warp knitting fabrics is between machine weaving and weft knitting. The fabric is softer and better than weft-knitted fabrics; the longitudinal and transverse elasticity is between woven fabrics and weft-knitted fabrics; the...
