Problems solved by technology

At present, flax elastic fabrics are generally woven by covering elastic fiber filaments with flax to form elastic core-spun linen yarns. However, the adhesion between flax fibers and elastic fiber filaments of this flax elastic yarn is not good, and it will appear after long-term use. Separation of flax fiber and elastic fiber filaments, causing product quality problems

Embodiment 1

[0022] A preparation method of a core-spun yarn of a built-in void type flax-coated XLA fiber, the steps are as follows:

[0023] S1. Flax treatment: select the raw hemp with a splitting index greater than or equal to 250, and beat the raw hemp into hemp; spray the hemp with an aqueous solution containing a wetting agent for humidification; The roving is spun into rovings on a drawing frame; the rovings are sequentially subjected to compound enzyme degumming treatment, storage, acid washing, sub-bleaching, alkali washing, oxygen bleaching, and water washing; the rovings are twisted by a spinning frame to make spun yarns; the flax The spun yarn is dried and wound; moisturizing for 18 hours; a total of 5 draw frames; after taking the four enzymes of pectinase, lipase, xylanase, and virilase and compounding them according to the ratio of 3:2:1:1, A degumming enzyme solution is prepared through tertiary fermentation; the degumming is performed by immersing the flax roving in the d...

Abstract

The invention discloses a preparation method of a core-spun yarn with a built-in void type flax-coated XLA fiber, which includes flax treatment, middle layer configuration, middle layer coating, and core-spun yarn; the invention passes the flax elastic core-spun yarn through 120 to 130 ℃ for 15 to 20 minutes, so that the middle layer is heat-cured to improve the adhesion of flax spun yarn, middle layer, and XLA elastic fiber filaments. At the same time, it is more important to foam the magnesium carbonate, so that the middle layer will be intermittent. The gaps are foamed out, so that the middle layer itself, between the middle layer and the linen spun yarn, and between the middle layer and the XLA elastic fiber filaments can produce a certain size of space to improve the resilience performance.

Description

technical field [0001] The invention relates to a preparation method of a core-spun yarn of a built-in void type flax-coated XLA fiber. Background technique [0002] Linen products have a long history and enjoy a high reputation in the world. Even today when silk, pure cotton, wool, man-made fibers and other fabrics are very developed, linen fabrics still occupy an irreplaceable noble position. The natural breathability, hygroscopicity, freshness and drainage of flax make it a free-breathing textile, which can reduce the human body's room temperature by 4-8°C at room temperature, which is called "natural air conditioner". At present, flax elastic fabrics are generally woven by wrapping elastic fiber filaments with flax to form flax elastic core-spun yarns. The separation of flax fiber and elastic fiber filaments causes product quality problems. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned shortcomings of the prior art, the problem to be solved by the ...
