Problems solved by technology

However, viscose fiber also has the disadvantages of poor wear resistance and elasticity, and high shrinkage rate is easy to deform
At the same time, some existing blending processes are dyed after blending, which is easy to damage the performance of spandex fiber in the later dyeing process, thereby affecting the quality of the entire core-spun yarn

Embodiment

[0025] The dope dyed core-spun yarn of the present invention includes a core yarn and a covering yarn, the covering yarn is located on the outer layer of the core yarn, the core yarn is spandex fiber, and the covering yarn is composed of 60-70% It consists of polyester fiber and 40-30% viscose fiber, both the polyester fiber and the viscose fiber are colored fibers, and the fineness of the spandex fiber is 30-60D.

[0026] The covered yarn is 70% polyester fiber and 30% viscose fiber; the fineness of the spandex fiber is 40D.

[0027] The preparation process adopted by the dope dyed core-spun yarn of the present invention is a siro compact spinning process, comprising the following steps:

[0028] S1: mixing the polyester fiber and viscose fiber and performing the blowing-carding and carding processes in sequence to obtain the mixed fiber;

[0029] S2: Composite the mixed fiber obtained in step S1 and the spandex fiber in a drawing process in a strip-mixed manner to obtain a ...

Abstract

The invention discloses dope dyeing core-spun yarn and a preparation process thereof. The dope dyeing core-spun yarn comprises core yarn and wrap yarn, the wrap yarn is located on the outer layer of the core yarn, the core yarn is spandex fiber, and the wrap yarn is composed of 60-70% of polyester fiber and 30-40% of viscose fiber, wherein the polyester fiber and the viscose fiber are colored fiber, and the fineness of the spandex fiber is 30-60D. The dope dyeing core-spun yarn is high in elastic capacity and strength, resistant to wrinkles and scalding, easy to wash, quick to dry, resistant to ultraviolet rays, smooth, cool, breathable, resistant to static electricity, gorgeous in dyeing, soft, comfortable and capable of meeting the skin physiology science of a human body.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a dope dyed core-spun yarn and a preparation process thereof. Background technique [0002] Spandex fiber is an elastic fiber with excellent stretchability and no aging. It is very popular in the processing of fabrics such as men's and women's underwear, fitness clothes, sportswear, competition clothes and casual clothes. However, this fiber cannot be woven alone , need to be woven together with other raw materials. Polyester fiber is also called polyester fiber. This fiber has high elasticity and strength, is anti-wrinkle, heat-resistant, easy to wash, quick-dry, and anti-ultraviolet. However, this material has poor hygroscopicity and air permeability, and it is easier to absorb dust. . Viscose fiber has excellent properties such as smooth and cool, breathable, antistatic, and brilliant dyeing, and has the most scientific moisturizing performance in line with human phy...
