Example Embodiment

[0009] Example 1:

[0010] The process of the special covered yarn described in this embodiment is to first combine a strand of glass filament and a strand of nylon filament to form a yarn core without stretching force, and then use a double twister to twist the yarn core S-shape, and the twist is It is 650. The twisted yarn core is put on the wrapping machine under the condition of applying tension to it, and the polyester fiber is wrapped outside the yarn core. Z-type twisting is used in the wrapping process, and the twist is also 650. After the twisting is completed, a special covered yarn product with high quality and strong fire resistance can be obtained, with glass fiber and nylon fiber as the core and polyester fiber as the outside.

Example Embodiment

[0011] Example 2

[0012] In the process of the special covered yarn described in this embodiment, the doubling yarn is two strands of glass yarn, the twist of the obtained yarn core is Z-type twist, the twist is 200, and then it is composed of polyamide fiber and viscose fiber. The mixed fiber is wrapped around the yarn core, and the twist is S-type twist, and the twist is 200. The obtained yarn core is glass fiber material, and the covered yarn material is wrapped with mixed fibers.

Abstract

The invention relates to a process for producing special covered yarn, which mainly comprises merging and twisting; after merging at least one yarn to form a yarn core, twisting the yarn core with a double twister, wherein the number of twists is 200-1800; and covering fibers on the twisted yarn core by using a covering machine, wherein the twisting direction in the covering process is opposite to the twisting direction of the yarn core, and the numbers of twists are the same. The technique does not need to carry out thermal-insulation setting on the covered yarn, and is especially suitable for covered yarn of which the core uses a high-temperature resistant material.

Description

technical field [0001] The invention relates to a spinning method, in particular to a process for producing special covered yarn and its products. Background technique [0002] Covered yarn is an excellent textile material with good elasticity, no pressure, stable size, good recovery, soft texture, comfortable movement, etc. It provides high-grade raw materials for textile, knitting, hosiery, clothing and other fields. During its production process, the fiber is twisted and coated on the core yarn, and the core yarn will also be twisted to a certain extent during the process of coating and twisting. In order to prevent the core yarn from returning to its original state after twisting and causing the covered yarn to shrink, heat preservation and setting processes are generally carried out to obtain a high-quality covered yarn. With the advancement of technology, more and more materials are applied to the production process of covered yarns, including some high-temperature-re...
