Problems solved by technology

At present, most of the fibers used for elastic yarn spinning are spandex, which has high elasticity, which is not conducive to the development of low-elasticity fields. Secondly, spandex is prone to decomposition, aging, breakage, resistance to repeated stretching, and sun exposure, etc. Defects limit its development to a certain extent, and the continuous emergence of new elastic fibers also creates more new design ideas for worsted elastic yarns
Elastic filaments such as spandex are mostly spun into yarns through a single method of core-spun, wrapping, and twisting. The simple core-spun yarn limits the composition of the fiber and affects its multi-component development, which is not conducive to the development of fibers and other long fibers. The interaction of filaments has certain restrictions on the structure and performance of yarns
The degree of cohesion of the wrapped yarn is low, which can easily lead to unsatisfactory wrapping effect and uneven yarn elasticity. The co-twisted yarn is prone to free core leakage under tension, so it needs to be produced on an improved twisting machine.
Spinning methods such as core wrapping, wrapping, and twisting of fibers and elastic filaments are not conducive to the synergy between wool and other filaments except elastic fibers, thereby limiting the structure of the yarn

Abstract

The invention discloses a processing method for compact Sirofil elastic yarns. The method includes that an elastic-filament pre-drafting device and a thread guide mechanism are additionally mounted on a compact core spinning frame; the elastic-filament pre-drafting device guides filaments and elastic filaments to enter front rollers through drafting rollers; roves are unwound from a rove reel and enter a drafting area formed by rear rollers, middle rollers and the front rollers through a yarn separator to be drafted by certain multiples; drafted roves together with two combined filaments enter a compacting area with a negative-pressure air intake device; compacted yarns are twisted and wound onto a bobbin to produce the compact Sirofil elastic yarns. By the processing method for spinning multicomponent yarns, winding and coring effects are achieved, spinning process is shortened, spinning end breakage is reduced, working efficiency of workshops is improved, and finished yarns have few fluff, high strength and good quality.

Description

technical field [0001] The invention relates to a yarn processing method, in particular to a processing method of agglomerated sirofil elastic yarn. Background technique [0002] With the change of people's demand for clothing, wool spinning products continue to develop towards refinement, high-quality, high value-added and high-tech boutiques while maintaining classic and elegant styles. Yarn is the basic composition of fabrics. Structural properties have an extremely important impact on fabrics. At present, most of the fibers used for elastic yarn spinning are spandex, which has high elasticity, which is not conducive to the development of low-elasticity fields. Secondly, spandex is prone to decomposition, aging, breakage, resistance to repeated stretching, and sun exposure, etc. Defects limit its development to a certain extent, and the continuous emergence of new elastic fibers also creates more new design ideas for worsted elastic yarns. Elastic filaments such as span...
