Preparation method of all-cotton high-count high-needle gage one-side weft plain knitted fabric

Abstract

The invention relates to a preparation method of an all-cotton high-count high-needle gage one-side weft plain knitted fabric. The method comprises the steps that a 60 / 1 tight spun yarn serves as a raw material, a one-side high-speed multi-track knitting machine serves as a weaving machine, preshrinking treatment is firstly carried out after weaving, then mercerization, dyeing and sizing are carried out to obtain the all-cotton high-count high-needle gage one-side weft plain knitted fabric. The preparation method of the all-cotton high-count high-needle gage one-side weft plain knitted fabrichas the advantages that the weaving machine is reasonably selected, the dyeing technology is reasonable, the mercerization technology and sizing technology are ingenious, the prepared fabric is light,thin and soft, bias-filling does not exist at all, the size stability is good, the stiffness, smoothness and rebound resilience are excellent, and the all-cotton high-count high-needle gage one-sideweft plain knitted fabric is a good choice for manufacturing slap-up women's wear.

Description

technical field [0001] The invention belongs to the field of weft plain knitted fabrics, in particular to a method for preparing all-cotton high-count and high-gauge single-sided weft plain knitted fabrics. Background technique [0002] As we all know, due to the spiral weaving method of the large circular knitting machine and the twist formed by the spinning of cotton single yarn, weaving flat knitting fabrics inevitably produce inclination, that is, weft skew. Although counterclockwise machine knitting can eliminate part of the skew, weft skew due to yarn twist is unavoidable. The usual solution is: 1. Use ply yarn instead of single yarn such as 120s / 2 instead of 60s / 1, which causes a substantial increase in cost. 2. Use single yarns with different twist directions, such as S.Z twisted yarns to weave alternately, and use different twist directions to generate torsion to offset each other to eliminate weft skew, but the fabric surface presents a corrugated shape, which is ...

Problems solved by technology

The usual solution is: 1. Use strands instead of single yarns such as 120s / 2 instead of 60s / 1, which causes a substantial increase in costs

2. Use single yarns with different twist directions, such as S.Z twisted yarns to weave alternately, and use different twist directions to generate torsion to offset each other to eliminate weft skew, but the fabric surface presents a corrugated shape, which is different from the appearance of normal weft jersey fabrics

Therefore, ordinary weft jersey fabrics are shaped according to the inclination to ensure that the garment will not be twisted in the future and affect the performance. However, the product grade is low visually. Due to the low twist of ordinary weaving yarn, the weft skew produced is acceptable, but the high count The maximum inclination of high-gauge weft plain stitch fabrics will reach more than 50 degrees, which will strictly affect the aesthetics of the appearance
