Production method of short staple enveloped composite yarn and its device

Abstract

The present invention discloses a production method of short fibre wrapped composite yarn and its equipment. Said invention is implemented by using spinning frame and wrapping device, and its production method includes the following steps: raw material, scotching, carding, drawing, roving, spinning and doffing.

Description

[0001] Application field [0002] The invention relates to a spinning technology, in particular to a production method and a device for short fiber wrapped composite yarn. Background technique [0003] In recent years, the types of composite yarn production technologies invented and industrialized in the world mainly include: core-spun yarn, wrapping yarn, siro spinning, sirofil spinning, etc. The production principles of these types of products are different, the product styles are different, and the application fields are diverse. Among them, the core-spun yarn refers to a yarn or filament as the core, which is twisted together with another outer fiber to form a yarn. The characteristic is that the output length of the core yarn and the outer fiber is the same during twisting, and the core yarn is not exposed. , the production methods include air-jet spinning, friction spinning, modified ring spinning, etc. Wrapped yarn refers to a filament as the core, and another outsourc...

AI Technical Summary

Problems solved by technology

The current wrapping composite yarn production technology uses at least one filament or yarn, the selection of raw materials and product application fields are limited, the production cost is high, and the excellent characteristics of various raw materials cannot be fully utilized.

For example, the traditional polyester-cotton blended fabric is fully mixed with cotton and polyester, spun into yarn, and then woven into cloth. Both fibers are exposed on the surface of the yarn, which affects the dyeing and wearing properties of the fabric.
