Problems solved by technology

At present, flax elastic fabrics are generally woven by flax-coated elastic fiber filaments to form flax elastic core-spun yarns, but the flax fibers and elastic fiber filaments of this flax elastic yarn do not fully utilize the elastic fiber filaments after core-wrapping. Elastic recovery ability, in addition, the connection between flax fiber and elastic fiber filament is not very stable

Embodiment Construction

[0021] The content of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] A preparation method of a flax-coated spandex elastic denim fabric, 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 Spinning yarn for drying and winding; moisturizing for 18-36 hours; a total of 5 draw frames; four enzymes, pectinase, lipase, xylanase, and virilase, are compounded in a ratio of 3:2:1:1 Then, through tertiary fermentation, a degumming en...

Abstract

The invention discloses a preparation method of an elastic denim fabric coated with flax. The steps are as follows: flax treatment, configuration of a rough layer, coating of a rough layer, core wrapping, and weaving; the invention first mixes polytetrafluoroethylene particles with organic bentonite Throw them into the water together, stir, and use organic bentonite to make the polytetrafluoroethylene particles in the suspension state in the whole system, and the dispersion is more uniform, so that the polytetrafluoroethylene particles are attached more uniformly on the outside of the rugged layer, and then the flax spun yarn The voids formed when wrapping the rugged layer are more uniform, resulting in more uniform elastic recovery properties.

Description

technical field [0001] The invention relates to a preparation method of a flax-covered spandex elastic denim fabric. 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. Elastic recovery ability, and the connection between flax fiber and elastic fiber filament is not very stable. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies of the above-mentioned prior art, the problem solved by the prese...
