Abstract

The present invention is characterized by that on the spinning machine it utilizes addition of a yarn tension control device and simple renovation of guide wheel to spin the invented core-spun composition yarn whose yarn is covered with staple fiber, and its covering rate is high. Said composite core-covered yarn not only has the appearance style, hand property, fluffy property and other advantages of staple fibre, but also possesses the strength and elongation, conformal property and drapping property, etc. of yarn.

Description

technical field

[0001] The invention belongs to the technical field of spinning in the textile industry, in particular to a method and a device for manufacturing a core-spun composite yarn in which short fibers are covered with filaments. Background technique

[0002] As we all know, composite (mixed) yarns between various fibers are called composite spinning (or blended). A new type of yarn with a sheath-core structure, which uses filaments as the skeleton yarn and forms short fibers covering the filaments, is a major development direction of new spinning in recent years.

[0003] Conventional filament staple fiber composite spinning is generally carried out on friction spinning, rotor spinning, Sirofil, ring twisting frame, hollow spindle spinning frame or ring spinning frame at present. Theoretically speaking, it is hoped that three structures can be realized through the above methods: that is, from the perspective of the yarn cross section, it can be divided into the fo...
