Embodiment 1

[0039] A spinning method of cotton-linen slub yarn, which comprises drawing cotton roving and linen roving separately, converging and accumulating, twisting and winding to obtain cotton-linen slub yarn;

[0040] The quantitative of cotton roving is 5g / 10m; the raw material of the hemp roving of hemp roving is ramie, and quantitative is 5g / 10m; The set twist of cotton and hemp fancy yarn is unchanged, and the set twist is 300 twist / m;

[0041] The drafting of cotton roving is independently drafted by drafting mechanism Ⅰ; the drafting of hemp roving is independently drafted by drafting mechanism Ⅱ; drafting mechanism Ⅰ and drafting mechanism Ⅱ are independently controlled;

[0042] The sum of the feeding weights of cotton roving and hemp roving remains unchanged; the feeding weight ratio of cotton roving and hemp roving changes linearly from 100:0 to 0:100 when transitioning from cotton yarn segment to hemp yarn segment; transitioning from hemp yarn segment to cotton yarn segmen...

Embodiment 2

[0046] A spinning method of cotton-linen slub yarn, which comprises drawing cotton roving and linen roving separately, converging and accumulating, twisting and winding to obtain cotton-linen slub yarn;

[0047] The quantitative of cotton roving is 10g / 10m; the raw material of the hemp roving of hemp roving is hemp, and the quantitative is 10g / 10m; the set twist of cotton twist fancy yarn remains unchanged, and the set twist is 400 twist / m;

[0048] The drafting of cotton roving is independently drafted by drafting mechanism Ⅰ; the drafting of hemp roving is independently drafted by drafting mechanism Ⅱ; drafting mechanism Ⅰ and drafting mechanism Ⅱ are independently controlled;

[0049] The sum of the feeding weights of cotton roving and hemp roving remains unchanged; the feeding weight ratio of cotton roving and hemp roving changes linearly from 100:0 to 0:100 when transitioning from cotton yarn segment to hemp yarn segment; transitioning from hemp yarn segment to cotton yarn...

Abstract

The invention relates to a spinning method of cotton-linen slub fancy yarn. Cotton roving and linen roving are drawn separately, converged and gathered, and then twisted and wound to obtain cotton-linen slub fancy yarn; cotton roving and linen roving The sum of the feeding weights remains unchanged; a cycle unit is formed by a cotton yarn section, a transition section from a cotton yarn section to a hemp yarn section, a hemp yarn section, and a transition section from a hemp yarn section to a cotton yarn section, and a cotton yarn section and a cotton yarn section transition The length ratio of the transition section to the hemp yarn section, the first hemp yarn section and the transition section from the hemp yarn section to the cotton yarn section is fixed; from the cotton yarn section to the hemp yarn section, the feeding weight ratio of cotton roving and hemp roving is from 100:0 to 0:100 linear change; from hemp yarn section to cotton yarn section, the feeding weight ratio of cotton roving to hemp roving changes linearly from 0:100 to 100:0. The fabric spun by the cotton-linen slub fancy yarn of the invention has softer hand feeling, stronger three-dimensional sense of fabric style, regular change of cloth surface, and is especially suitable for the field of clothing and other fabrics.

Description

technical field [0001] The invention belongs to the technical field of cotton-linen blended spinning, and relates to a method for spinning cotton-linen slub fancy yarn, in particular to a method for ring-spinning cotton-linen slub fancy yarn. Background technique [0002] At present, with the advancement of spinning technology, ring spinning can not only spin ordinary yarns, but also spin various fancy yarns such as slub yarns and segmented colored yarns. Such as figure 2 As shown, when spinning fancy yarns by ring spinning, two rovings are usually fed into the drafting device of the spinning frame at the same time, and the drafting device can draft the two rovings at the same time or intermittently respectively. drafting effect. The specific measures adopted are: the drafting device of the spinning frame is composed of four rollers, and the two rovings are respectively fed by the two rollers behind the drafting area, and the front roller and middle roller of the spinning ...
