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 cotton and linen slub yarns are composed of a plurality of cotton yarn sections, a plurality of linen yarn sections and transition sections connecting the cotton yarn sections and the linen yarn sections; the lengths of the cotton yarn sections, the linen yarn sections and the transition sections are randomly changed, and the length change is controlled by a programmable controller; the sum of the feeding weights of the cotton rough yarns and the linen rough yarns is not changed; when the cotton yarn sections are transited to the linen yarn sections, 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 sections are transited to the cotton yarn sections. A fabric spun by the cotton and linen slub yarns spun by the method is softer in hand feeling, rich and changeable in fabric style and stronger in cloth cover color sense, and the cotton and linen slub yarns are particularly suitable for the field of fabrics of decoration and the like.

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 ...
