Problems solved by technology

At present, flax elastic fabrics are generally woven with 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 are generally directly covered together, so that the covered yarn The rebound performance of the yarn has not been fully diverged, so it is necessary to further improve the elasticity of the covered yarn

Abstract

The invention discloses a high-elasticity flax fabric and a preparation process thereof. The fabric is formed by weaving flax core-spun yarn; and the flax core-spun yarn comprises a spandex fiber layer, bonding spun yarns and a flax fiber layer. Spandex fiber filaments and soluble polyester fibers are subjected to wrapping processing through a wrap yarn machine to obtain a wrapping structure in which the soluble polyester fibers are wrapped by the spandex fiber filaments; then the plurality of bonding spun yarns obtained through electrostatic spinning and the outer sides of the peripheries of the spandex fiber filaments are subjected to drawing and bonding, so that the spandex fiber filaments are well positioned and reinforced; then the soluble polyester fibers are washed with water, so that hollow structures are formed in the spandex fiber filaments, and the springback capacity of the spandex fiber filaments is greatly improved; and meanwhile, due to the fact that strip-shaped gaps are formed between the bonding spun yarns, the bonding spun yarns play a role in stably bonding the spandex fiber filaments and do not obstruct the air permeability of the spandex fiber filaments, and the whole structure is breathable and smooth.

Description

Technical field [0001] The present invention relates to a highly elastic linen fabric and its preparation process. Background technique [0002] Linens long history and reputation in the world, even in silk, cotton, wool, rayon and other fabrics very developed today, linen still occupies an irreplaceable noble status. Flax natural permeability, moisture absorption, and the discharge of fresh, making textile breathe freely, can sense the body temperature drop chamber 4 ~ 8 ℃, referred to as natural air conditioning at room temperature. Currently linen flax stretch fabric generally produced by covering an elastic fiber filament, formed elastic core yarn woven flax, flax fibers but this elastic fiber filament flax stretch yarn is generally coated directly together, so that the covered yarn rebound performance has not been fully divergent, so the need to further increase the flexibility of covered yarn. Inventive content [0003] For the above-described shortcomings of the prior art...
