Embodiment 1

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

[0023] S1. Flax treatment: select raw flax with a splitting degree greater than or equal to 250 pieces, and beat the raw flax into flax; spray the flax with an aqueous solution containing a humidifying agent for humidification; then use a sliver machine to make flax, and flax successively The roving is spun into roving on a drawing frame; the roving is sequentially subjected to compound enzyme degumming treatment, stacking, pickling, sub-bleaching, alkali washing, oxygen bleaching, and water washing; the roving is twisted into spun yarn by a fine spinning machine; The spun yarn is dried and wound; the moisture is kept for 18 hours; the drawing frame has a total of 5 passages; after the four enzymes of pectinase, lipase, xylanase and cellulase are compounded according to the ratio of 3:2:1:1, The degumming enzyme solution is prepared through three s...

Abstract

The invention discloses a preparing method of built-in void type core spun yarn with linen wrapping XLA fibers. The method comprises linen treatment, middle layer configuration, middle layer coating and core spinning. Linen stretch core spun yarn is heated and cured for 15 to 20 min at the temperature of 120 to 130 DEG C, a middle layer is heated and cured, the attaching degree of linen spun yarn,the middle layer and XLA stretch fiber filaments can be improved, meanwhile, more importantly, magnesium carbonate is subjected to foaming, accordingly, intermittent voids can be foamed out of the middle layer, and the voids with the certain sizes can be generated in the middle layer, the position between the middle layer and the linen spun yarn, and the position between the middle layer and theXLA stretch fiber filaments to improve the springback property.

Description

technical field [0001] The invention relates to a preparation method of a core-spun yarn with a built-in void type linen-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. Flax's natural air permeability, hygroscopicity, freshness and drainage make it a freely breathing textile. At room temperature, it can reduce the temperature of the human body's room by 4-8°C, and it is called "natural air conditioner". 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 the 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 fibers and elastic fiber filaments, res...
