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 an elastic breathable fabric based on hollow covering yarns and a preparation process of the elastic breathable fabric. The fabric is formed by spinning the hollow covering yarns; and the hollow covering yarns comprises XLA elastic fiber layers, annular bonding layers and linen fiber layers. Hollow structures are formed in XLA elastic fiber filaments, so that the springback capacity of the XLA elastic fiber filaments are greatly improved; and meanwhile, due to the fact that annular breathable gaps are formed between the annular bonding layers, the annular bonding layers have the stable bonding effect on the XLA elastic fiber filaments and meanwhile do not block the breathability of the XLA elastic fiber filaments, and the whole structure is breathable and smooth.

Description

technical field [0001] The invention relates to an elastic air-permeable fabric based on a hollow core-spun yarn and a preparation process thereof. 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 gas 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 a natural air conditioner. 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 ...
