Spinning method for siro compact spinning large-difference-proportion short fiber skin-core wrapped yarn

Abstract

The invention discloses a spinning method of a siro compact spinning large-difference-proportion short fiber skin-core fasciated yarn, which specifically comprises the following steps: two raw materials A and B with different properties are respectively and independently subjected to opening and cleaning, carding, drawing and roving procedures according to processing requirements to be independently prepared into roving, the roving A contains small-proportion fibers and needs to be independently and repeatedly subjected to opening and cleaning, carding, drawing and roving procedures once, and the roving B contains small-proportion fibers; after roving is made, the roving A and large-proportion fibers are fed at the drawn sliver feeding position at the same time to produce roving A, then the roving A is fed into a drafting area through a double-eye horn mouth on a siro compact spinning frame and output after drafting and gathering, fiber strands are output, the principle that the fiber strands on the right side wrap the fiber strands on the left side is utilized, and twisting is conducted in a staggered spinning mode to form yarn; according to the method, the technological process of spinning the core filament staple fiber yarn in advance is reduced, the problem of cloth cover crosspiece caused by core filament fiber leakage is solved, yarn hairiness can be greatly reduced, the yarn strength is improved, and the yarn quality is improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spinning method of siro compact-spinning staple fiber sheath-core-wrapped yarn with a large difference ratio. Background technique [0002] In recent years, the situation of the textile industry has continued to be sluggish, and the market competition has become increasingly fierce. The single product variety structure of traditional cotton spinning enterprises can no longer meet the diversified market demand. It is imminent to adopt new technologies, develop new products, and drive enterprise transformation and upgrading with innovation. [0003] The traditional core-spun yarn spinning technology is to pass the spun yarn through a spun yarn core-spun yarn device to form a core-spun structure. In this case, a small proportion of fibers needs to be spun into reverse twist spun yarn, and then a large proportion of fibers are spun into rovings. The spun yarn uses a small proport...

AI Technical Summary

Problems solved by technology

This need to spin a small proportion of staple fibers into yarns increases the cost, the application range of the fibers is limited, and there is a phenomenon of core fiber leakage, which causes problems such as intermittent weaving of the cloth surface.
