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...

Abstract

The invention relates to a spinning method for cotton and linen slub yarns. The method comprises the following steps of drafting cotton rough yarns and linen rough yarns, performing gathering, performing twisting, and performing winding to obtain the cotton and linen slub yarns. The sum of the feeding weights of the cotton rough yarns and the linen rough yarns is not changed; a cotton yarn section, a transition section from the cotton yarn section to a linen yarn section, the linen yarn section and a transition section from the linen yarn section to the cotton yarn section form a circulation unit; the length ratio of the cotton yarn section, the transition section from the cotton yarn section to the linen yarn section, the linen yarn section and the transition section from the linen yarn section to the cotton yarn section is a constant value; when the cotton yarn section is transited to the linen yarn section, the feeding weight ratio of the cotton rough yarns to the linen rough yarns is linearly changed from 100:0 to 0:100; and the feeding weight ratio of the cotton rough yarns to the linen rough yarns is linearly changed from 0:100 to 100:0 when the linen yarn section is transited to the cotton yarn section. A fabric spun by the cotton and linen slub yarns spun by the method is softer in hand feeling, stronger in fabric style stereoscopic impression and regular in cloth cover change, and the cotton and linen slub yarns are particularly suitable for the field of fabrics such as clothes.

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 ...
