Preparation method of pure-cotton self-twisted spun-yarn home textile

Abstract

The invention relates to a preparation method of pure-cotton self-twisted spun-yarn home textile. The preparation method comprises the steps of 1) discharging cotton fibers, drafted and elongated to 25-35 mm in length, from front rollers to pick-up rollers, and discharging the cotton fibers that are twisted from yarn guide hooks to obtain pure-cotton yarns, wherein distances from the front rollersto the pick-up rollers are less than the length of the cotton fibers, the pick-up rollers have a stroke of 6-7.2 mm, cycle length of self-twisted yarns is 60-75 mm, and distances from the pick-up rollers to the yarn guide hooks are 10-15 mm; 2) warping the obtained pure-cotton yarns, slashing the warped yarns, drafting the slashed yarns, and weaving the drafted yarns; 3) singeing the obtained fabric, desizing the singed fabric, scouring the desized fabric, subjecting the scoured fabric to oxygen bleaching, mercerizing the bleached fabric, and dyeing the mercerized fabric.

Description

technical field [0001] The invention relates to a method for preparing a home textile fabric, in particular to a method for preparing a home textile fabric woven from pure cotton self-twisting yarn. Background technique [0002] The spinning process is one of the most important processes in textile production, and the quality of the yarn directly affects the quality of the fabric. Due to the increasing requirements on yarn quality and the increasingly fierce competition in the spinning market, spinning costs must be continuously reduced. [0003] Since the invention of the ring spinning machine in the United States in 1828, it has become the most widely used spinning method at present. However, the low output per spindle is a shortcoming of ring spinning. To further increase the spinning speed and increase the output, there are many limiting factors. Therefore, from the spinning principle, many new spinning methods different from the traditional ring spinning have emerged....

AI Technical Summary

Problems solved by technology

At a certain distance at the confluence, due to the increase in spinning speed, the two strands cannot be twisted well, and there is self-untwisting of a single strand, resulting in a decrease in the overall self-twisting twist

[0010] Influenced by these actual factors, some of the twisting efficiency is greatly reduced, and the theoretical calculation value does not match the actual situation.

Some are not reflected in theoretical calculations, but in actual production, they affect the twisting efficiency all the time
