Embodiment 1

[0013] Embodiment one: process 40S / 2 single jersey with 40S / 1 combed pure cotton raw yarn, its specific processing steps are:

[0014] (1) 40S / 1 combed pure cotton raw yarn is dyed and processed into 40S / 1 combed pure cotton white yarn and 40S / 1 combed pure cotton black yarn according to the traditional cheese dyeing process;

[0015] (2) Parallel a 40S / 1 combed pure cotton white yarn and a 40S / 1 combed pure cotton black yarn on the doubling machine to form a 40S / 2 combed ply yarn, and then combine the combined 40S / 1 2 Combed ply yarn is twisted on the twisting machine according to 60% of the twist (59±5 twist / 10 cm) of the middle twist yarn of the same yarn count, so that the twist of 40S / 2 combed ply yarn after twisting is 35 ±5 twists / 10cm;

[0016] (3) Weave the twisted 40S / 2 weakly twisted ply yarn on a circular knitting machine into gray fabric;

[0017] (4) Put the woven gray cloth into the overflow dyeing vat, control the weight ratio of gray cloth to water to 1:15, ...

Embodiment 2

[0022] Embodiment two: process 60S / 2 piqué fabric with 60S / 1 combed pure cotton raw yarn, its specific processing steps are:

[0023] (1) 60S / 1 combed pure cotton raw yarn is dyed and processed into 60S / 1 combed pure cotton white yarn and 60S / 1 combed pure cotton purple yarn according to the traditional cheese dyeing process;

[0024] (2) Parallel a 60S / 1 combed pure cotton white yarn and a 60S / 1 combed pure cotton purple yarn on the doubling machine to form a 60S / 2 combed ply yarn, and then combine the combined 60S / 1 2 Combed ply yarn is twisted on the twisting machine according to 45% of the twist (85±5 twist / 10 cm) of the middle twist yarn of the same yarn count, so that the twist of 60S / 2 combed ply yarn after twisting is 38 ±5 twists / 10cm;

[0025] (3) Weave the twisted 60S / 2 weakly twisted ply yarn into gray cloth on a circular knitting machine;

Abstract

The invention discloses a method for processing a soft twist yarn knitted fabric. The method is characterized in that: the whole process sequentially comprises the following specific steps of: yarn dyeing, doubling and twisting, weaving, fabric water-washing, softening finishing, dehydration, scutching and drying, calendering and shaping. The method has the advantages that: two single yarns are doubled to form a soft twist yarn so as to overcome the shortcomings of weak strength, weaving difficulties, severe cloth cover skewing and the like of the conventional single soft twist yarn; the method is simple in process; the knitted fabric processed by the method has the effects of elegant gloss, high size stability, fluffy and soft handfeel and the like; in addition, if two single yarns with different colors and an identical yarn count are doubled and twisted, the processed knitted fabric has a unique heather effect.

Description

technical field [0001] The invention relates to a method for processing fabrics in the field of textiles, in particular to a method for processing fabrics knitted with weakly twisted yarns. Background technique [0002] Knitted fabric clothing is deeply loved by consumers because of its clear lines, soft bulkiness, elasticity, and comfortable wearing. In the yarn used for knitted fabrics, it is usually required that the yarn has good strength, which is beneficial to circular knitting machine weaving and subsequent dyeing and finishing; The level of twist can be divided into strong twist yarn, medium twist yarn and weak twist yarn. At present, most knitted fabrics use medium twist yarn, that is, ordinary yarn. Weak twist yarn is to reduce the twist of the yarn according to the product performance requirements, which is lower than the twist of the conventional yarn of the same yarn count, and the reduction of the twist of the yarn will reduce the strength of the yarn. If th...
