A device and method for double-zone drafting of cashmere roving and slippery drafting of spun silk

Abstract

The invention belongs to the technical field of ring spinning, and relates to a double-zone drafting of cashmere roving and slippery drafting of spun silk siro spinning device and method. A cashmere roving dual-zone drafting and spun silk slippery drafting Siro spinning device, including a double-hole bell mouth, a rear drafting zone, a middle drafting zone, a front drafting zone, a yarn guide, a cluster and a yarn guide Great. The double-hole bell mouth, rear drafting area, yarn guide, middle drafting area, bundler, front drafting area, yarn guiding rod and yarn guiding hook are fixed on the vehicle surface in sequence. The present invention achieves the purpose of blending two kinds of fibers with different lengths by simply modifying the drafting accessories of the semi-worsted spinning frame, combined with the yarn guide in the rear area and the cluster in the front area, and especially solves the problem of cashmere spinning in the semi-worsted spinning frame. The problem of blending fibers with longer spun silk fibers, the blended yarn has less hairiness, a smoother surface, clear texture, and is almost close to the appearance of worsted woolen yarn.

Description

technical field [0001] The invention belongs to the technical field of ring spinning, and relates to a double-zone drafting of cashmere roving and slippery drafting of spun silk siro spinning device and method. Background technique [0002] Wool spinning is a spinning process that processes wool fibers into yarn. The wool fiber is mainly wool, and also includes special animal fibers such as cashmere, rabbit hair, mohair, and yak hair. The wool spinning process is mainly divided into three categories: wool wool spinning, wool semi-worsted spinning and wool worsted spinning. The difference is mainly due to the difference in the technological process, and the root cause is that the difference in the length of the wool fiber leads to the difference in the processing technology and equipment. The wool fiber used in woolen spinning is relatively short, the yarn count is thicker, the grade is lower, the yarn has better plushness and soft hand feeling, and is used for weaving wool...
