Problems solved by technology

[0004] The above-mentioned high-twisted cotton gray fabric processing technology has the following defects: although the twisted yarn has been shaped by steaming and vacuuming, the yarn just after wet steaming is still relatively hot, and it is still easy to weave directly. There is a phenomenon of deformation, and the shaping effect is not very ideal

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] An improved production process of cotton knitting yarn disclosed by the invention comprises the following steps:

[0037] A. Twisting: Select 140 single high-quality cotton embryo yarns, twist each strand to 800-1000 twists (preferably 800 twists or 900 twists or 1000 twists), and then twist two strands to 600-800 twists (preferably 600 twist or 700 twist or 800 twist);

[0038] B. Wet steaming: put the twisted yarn 14 into the yarn steaming machine for wet steaming, and the temperature is controlled at 100-120 degrees (preferably 100 degrees or 110 degrees or 120 degrees);

[0039] C, cooling: the yarn 14 after wet steaming is unwinded, and the yarn 14 that is unwound is carried out blowing cooling process by blowing device 1, and the air outlet direction of blowing device 1 is the direction that yarn 14 conveys, and yarn 14 through the air outlet o...

Abstract

The invention relates to a cotton knitting yarn improvement production process, and belongs to the technical field of spinning. The cotton knitting yarn improvement production process comprises the following operation steps of A, twisting: selecting 140 pieces of single high-quality cotton raw yarns, twisting single pieces to obtain 800 to 1000 twists, and then merging and twisting two strands toobtain 600 to 800 twists; B, wet steaming: placing the twisted yarn into a yarn steaming machine for wet steaming, and controlling the temperature to range from 100 to 120 DEG C; C, cooling: immediately carrying out air blast cooling treatment on the wet-steamed yarn; D, singeing: singeing the cooled and shaped yarn on a singeing machine; and E, dyeing: dyeing the singed yarn. According to the cotton knitting yarn improvement production process, the yarn is cooled after being subjected to high-temperature wet steaming, so that the produced yarn is not easy to deform, and a shaping effect is better.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an improved production process of cotton knitting yarn. Background technique [0002] The twist of traditional yarn is generally based on the critical twist coefficient to determine the optimal twist. After the twist coefficient is higher than the critical twist coefficient, the strength will decrease with the increase of twist, but as the twist increases, especially the twist is more than 1.5 times of the critical twist coefficient. At the same time, the cotton fabric will have the characteristics similar to the hemp fabric: the air permeability is increased, and it has obvious cool feeling. Such as the "ice cotton yarn" variety of strong twist yarn popular in the Japanese market. [0003] The Chinese patent with application number 201810325178.1 discloses a high-twisted cotton gray fabric processing technology, including yarn technology and weaving technology. Twisting-setti...
