A/B siro spinning slub yarn produced from cotton fiber, viscose fiber and polyester fiber and its blending process

Abstract

The invention provides an A / B sirospun bunchy yarn blended with cotton fiber, viscose fiber and polyester fiber and blending technology, and the A / B sirospun bunchy yarn comprises 55+ / -1% cotton fiber, 10+ / -1% viscose fiber, and polyester fiber as the balance; the A / B sirospun bunchy yarn blending technology comprises the steps of obtaining a cotton fiber pre-merging strip by cotton fiber series operations; obtaining a viscose fiber pre-merging strip by viscose fiber series operations; processing the cotton fiber pre-merging strip and the viscose fiber pre-merging strip to produce an A rove; producing a B rove by polyester fiber series operations; feeding the A rove and the B rove into a spinning machine at the same time, and producing the A / B sirospun bunchy yarn through a CCZ-8 fancy yarn apparatus. According to the invention, the problems of unstable blending proportion, severe fiber loss, crosspiece caused by single dying or double dying are solved; and the product quality and class are raised greatly.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to an A / B siro spinning slub yarn produced from cotton fibers, viscose fibers and polyester fibers and a blending process thereof. Background technique [0002] In recent years, with the diversification of clothing fabrics, slub yarn, as a kind of fancy yarn, has been widely used in the design and development of new fabrics. Siro spinning is a new type of composite spinning yarn. Its siro yarn has the strength and style similar to that of double-ply yarn. The clothing fabrics made of it are smooth and soft, moisture-absorbing and breathable, bright in luster, and anti-pilling The effect is obvious, so it is more and more widely used in the cotton spinning industry. [0003] Through the research on the multi-component A / B siro spinning slub yarn series products, it is found that due to the large difference in the ratio and weight of the two rovings of A / B, and the difference in the...

Problems solved by technology

[0003] Through the research on the multi-component A / B siro spinning slub yarn series products, it is found that due to the large difference in the ratio and weight of the two rovings of A / B, and the difference in the number of fibers at the slub and the pitch of the spun yarn, the resulting blending ratio Large discrepancies, large loss of spun yarn fibers, single-dyeing and double-dyeing problems such as rungs are prominent, and production is extremely difficult

[0004] The blending process and control method in the prior art produces A / B siro spinning slub varieties. When the difference in the blending ratio of the A / B two rovings is more than 10%, the difference in the blending ratio of the yarn in the spinning process reaches more than 2.5%, and the fiber in the spinning process The loss is serious, and part of the fibers are completely lost, resulting in the lack of one kind of fiber on the single-dyed and double-dyed cloth surface, and the cloth surface has serious rungs

As a result, customers cannot accept this quality yarn, which affects the company's market share
