Problems solved by technology

However, high-count and high-density fabrics have high requirements for yarn quality and loom performance. Due to the influence of yarn breaking strength and hairiness, high-count fabrics are prone to weaving defects during the weaving process, and the yield is not high. To a certain extent Limits the wide application of high-count yarn

Abstract

The invention relates to a method for processing a high-count and high-density cotton knitted fabric, which comprises the following steps of yarn preparing, weaving, dyeing, drying, scutching, shaping and preshrinking. The yarn used in the step of yarn preparing is 100 percent Egypt long stapled cotton; the yarn adopts a compact spinning method; the twist of the yarn is 100 to 130 twists per 10 centimeters; and a double-faced knitting machine with a high stitch length is adopted in the step of weaving. In the invention, the double-faced knitting machine with the high stitch length can weave out the high-count and high-density cotton knitted fabric with high yield by selecting the raw material of the yarn, the twist and the spinning method; the twist of the yarn is between the knitting twist and the weaving twist, so the intensity of the yarn is improved, the yarn has high good weaving performance, and avoids knit fault; and the compact spinning method changes the structure of the yarn, so that the yarn has higher intensity, reduces hairiness and avoids flying, and the machine has good running state.

Description

technical field [0001] The invention relates to a processing method of cotton knitted fabrics, in particular to a processing method of high-count and high-density cotton knitted fabrics. Background technique [0002] At present, chemical fibers, such as polyester and nylon, are the most widely used on high-gauge double-sided knitting machines. They are often used to weave functional fabrics, because the yarn surface structure and breaking strength of chemical fibers can meet the weaving requirements of high-gauge knitting machines. There are few manufacturers who weave high-count cotton yarns on high-gauge double-knitting machines. The main reasons are as follows: First, high-gauge double-knitting machines have high requirements for yarn quality. It is easy to form weaving defects, and it is easy to cause damage to the knitting needles, resulting in machine loss; secondly, high-count yarns have relatively high requirements for cotton blending, not only requiring high quality...
