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 further described in detail below in conjunction with the accompanying drawings.

[0022] A preparation method of an elastic denim fabric covered with linen, 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; Drying and winding of spun yarn; moisturizing for 18-36 hours; 5 draw frames in total; four enzymes, pectinase, lipase, xylanase and cellulase, are compounded according to the ratio ...

Abstract

The invention discloses a preparation method of an elastic jean fabric with spandex coated with flax. The preparation method comprises the following steps of: treating flax, preparing a rugged layer,coating the rugged layer, covering a core and weaving. According to the preparation method disclosed by the invention, polytetrafluoroethylene particles and organic bentonite are put into water together and are stirred; the polytetrafluoroethylene particles are at a suspension state in a whole system by utilizing the organic bentonite and are more uniformly dispersed, so that the polytetrafluoroethylene particles are more uniformly attached on the outer side of the rugged layer, and furthermore, gaps formed when the rugged layer is coated with flax spun yarns are more uniform, and furthermore,the elastic recovery performance is more uniform.

Description

technical field [0001] The invention relates to a preparation method of elastic denim fabric covered with flax. 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 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 the flax fiber and the elastic fiber fil...
