Spinning method of woolen spinning system for spinning wrap yarns

Abstract

The invention relates to a spinning method of a woolen spinning system for spinning wrap yarns. The spinning method comprises a first kind of spinning method, a second kind of spinning method, a third kind of spinning method, a fourth kind of spinning method and a fifth kind of spinning method. The first kind of spinning method comprises the concrete steps that chemical fiber filaments are directly fed into a hollow spindle from a front roller through a feeding roller instead of a drafting device; a bobbin of woolen spun yarns sleeves the hollow spindle and is rotated along with the hollow spindle to wind on the filaments, and yarn covered filament type fasciated yarns of woolen spun yarn covered chemical fiber filaments are obtained, wherein the drafting device sequentially comprises a rear roller, a middle roller and a front roller from top to bottom, and the rear roller, the middle roller and the front roller are arrayed slantways. According to the spinning method of the woolen spinning system for spinning the wrap yarns, different types of wrap yarns are spun through selecting different drafting devices, and the process step is simple, and the prepared wrap yarns are good in hand feeling, good in heat preservation and uniform in finished yarns.

Description

technical field [0001] The invention relates to a spinning method of covered yarn, in particular to a spinning method of spinning covered yarn on a wool spinning system. Background technique [0002] Cover spinning, also known as wrap spinning, is a new spinning technology that uses hollow spindles for spinning. It uses filament or untwisted parallel staple fiber as the core yarn, and the outsourcing filament or spun yarn wraps the core yarn in a spiral manner. The common covering spinning methods are as follows: one is that the yarn core and the outer fiber are both short fibers; the other is that the yarn core is made of filament, and the short fiber is the outer fiber; the other is that the short fiber bundle is used as the yarn core. The outside is wrapped with filaments; there is also a filament that is used for both the yarn core and the outer fiber. The yarn strength of synthetic filament covered yarn is higher than that of general staple fiber covered yarn, but the...

Problems solved by technology

The yarn strength of synthetic filament covered yarn is higher than that of ordinary staple fiber covered yarn, but the surface of the yarn lacks the characteristics of natural fibers
