Abstract

The invention discloses a high-strength and low-stretch bio-based fiber fabric and a preparation method thereof. Viscose staple fibers are used as raw materials, and viscose staple fibers are opened and carded into strips to obtain raw viscose staple fibers, and then two or more viscose staple fibers are used Short fiber raw sliver is made into yarn by air spinning, vortex spinning, or ring spinning after drawing; the warp and weft knitting of the yarn is done to obtain gray cloth, which is then made by one-bath and one-step method; the finished product of the fabric The indicators are: transverse shrinkage ≤-3%, vertical shrinkage ≤-2%, bursting strength 280-320N, pilling resistance 4-5, radial water swelling 22-26, The twist rate after washing is ≤3%, the color fastness to wet rubbing is 4-5, the color fastness to dry rubbing is 4-5, and the abrasion resistance is >30,000 times. It is a fabric with good moisture absorption, good air permeability, skin-friendly, good pilling resistance, good color fastness, and good dyeing quality, which meets market demand and improves people's living standards.

Description

Technical field[0001]The invention relates to a fabric and a preparation method, in particular to a high-strength low-elongation bio-based fiber fabric and a preparation method, and belongs to the technical field of textile manufacturing.Background technique[0002]High-strength and low-stretch viscose staple fiber (product name: Yasser) is made of 100% natural bio-based materials. It is a kind of strength and elongation index similar to Modal fiber. It has good water absorption, air permeability and skin-friendliness. A new type of textile fiber raw material. It has high-strength, low-elongation fiber characteristics, and its dry breaking strength and wet breaking strength are increased by about 40% compared with ordinary bio-based short fibers. It can be widely used in vortex spinning, Siro spinning and Siro compact spinning 80S In the above high-count yarn field, the product price is 5000 yuan per ton lower than modal fiber, which has a very high product cost performance.[0003]With...
