Embodiment 1

[0038] A method for spinning cotton-twisted fancy yarns, in which cotton rovings and hemp rovings are drawn separately, converged and gathered, twisted and wound to obtain cotton-twisted fancy yarns;

[0039] Cotton roving quantitative is 5g / 10m; The raw material of the hemp roving of hemp roving is ramie, quantitative is 5g / 10m; The set twist of cotton and hemp fancy yarn is constant, and set twist is 300 twist / m;

[0040] 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 alternately from 70:30 to 30:70 and then to 70:30, specifically: when the proportion of cotton fiber When linearly increasing, hemp fiber decreases linearly in proportion; when the proportion of cotton fiber decreases linearly, hemp fiber increases linearly in proportion;

[0041] The drafting of cotton roving is independently drafted by drafting mechanism Ⅰ; the drafting of hemp roving is independently drafted...

Embodiment 2

[0045] A method for spinning cotton-twisted fancy yarns, in which cotton rovings and hemp rovings are drawn separately, converged and gathered, twisted and wound to obtain cotton-twisted fancy yarns;

[0046] The quantitative value of cotton roving is 8g / 10m; the raw material of hemp roving is flax, and the quantitative value is 8g / 10m; the set twist of cotton and hemp fancy yarn remains unchanged, and the set twist is 400 twists / m;

[0047] 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 alternately from 70:30 to 30:70 and then to 70:30, specifically: when the proportion of cotton fiber When linearly increasing, hemp fiber decreases linearly in proportion; when the proportion of cotton fiber decreases linearly, hemp fiber increases linearly in proportion;

Abstract

The invention relates to a spinning method of cotton and hemp fancy yarns. Cotton rovings and hemp rovings are drawn separately, converged and gathered, and then twisted and wound to obtain cotton and hemp fancy yarns; the sum of the feeding weights of cotton rovings and hemp rovings Unchanged; the feeding weight ratio of cotton roving and hemp roving is alternately changed from 70:30 to 30:70 and then to 70:30, and the cyclical alternation of feeding weight ratio of cotton roving and hemp roving is a linear increase of reciprocating or decrease linearly. The spinning method of the spun cotton-twist fancy yarn of the present invention realizes the independent drafting of the cotton fiber and the hemp fiber, the drafting quality is better, the quality of the spun fancy yarn is better, and the cotton-twist fancy yarn spun by the present invention The proportion of yarn cotton fiber and hemp fiber changes alternately, so that the yarn presents a surface appearance style similar to slub yarn, which not only broadens the types of cotton and hemp yarn, but also makes the spun yarn endow the fabric with many advantages such as softness and three-dimensionality.

Description

technical field [0001] The invention belongs to the technical field of cotton and hemp mixed spinning, and relates to a spinning method of cotton and hemp fancy yarn, in particular to a method for ring spinning cotton and hemp 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 fram...
