A production method capable of reducing shrinkage of wool yarn

Abstract

The invention relates to a production method capable of reducing shrinkage of wool yarn, comprising the following steps: A, pre-loosening; B, dyeing, improving the dyeing vat into an internal and external osmotic dyeing vat, and then putting pre-loosed wool balls into an internal and external osmotic dyeing vat. Dyeing treatment in the dyeing vat at regular intervals; C, braised wool, adding and adding crude oil to regular dynamic tumbling braised wool for more than 12 hours; D, one needle comb; E, two needle combs; F, re-combing; G, three Needle comb; H, made hair ball; I, the last needle comb; J, the last two needle combs; K, the last three needle combs; L, the last four needle combs; M, roving; N, the roving in Place in an environment with a humidity of 80% to 85% for 22 to 24 hours; O, spun yarn, improve the original smooth middle roller into a needle loop type middle roller, and improve the original smooth middle top roller into a needle loop type middle top roller; P, doubling; Q, two-for-one twisting; R, steamed yarn, the traditional static steamed yarn device is improved into a dynamic steamed yarn device, thereby greatly reducing shrinkage.

Description

【Technical field】 [0001] The invention relates to the technical field of spinning, in particular to a production method capable of reducing shrinkage of wool yarn. 【Background technique】 [0002] Wool itself is a material that curls easily. Its advantage is that it is soft, and the fibers are tightly interlocked to form a ball, which can produce the effect of heat preservation. Wool is inherently absorbent and can absorb up to a third of its weight in water. Because of this, the wool itself is not easy to be burned and has the effect of fire prevention. Wool fiber is soft and elastic, and can be used to make woolen wool, woolen yarn, blankets, felt and other textiles. Wool yarn has the advantages of full hand feeling, good warmth retention, and comfortable wearing. The disadvantage of wool yarn is its large shrinkage rate. As a result, it leads to uneven evenness, inability to shape the finished product, shrinkage, poor stability, unclear stripes, and uneven fabric. [0...
