Flame-retardant viscose 35s siro spinning process

Abstract

The invention discloses a hemp flame-retardant viscose 35s siro spinning process. Hemp and double-carding cotton are adopted and subjected to siro spinning directly with flame-retardant viscose fibers. Siro spinning yarn produced by the process has good quality, the hairiness, strip dryness and strength index of finished yarn are superior to those of ring spinning yarn, and the siro spinning yarnis a high-quality material for high-grade knitted underwear, clothing and bedding. The siro spinning yarn is compact in structure, few in feather, smooth in appearance, good in wearing resistance, soft in hand feeling and good in air permeability, drapability, wrinkle resistance and pilling resistance.

Description

technical field [0001] The invention relates to the textile field, in particular to a flame-retardant viscose 35s siro spinning process. Background technique [0002] Hemp fiber is a natural plant with good hygroscopicity, comfort, drape and stiffness and good dyeability. In addition, it can be blended with cotton, wool, hemp, nitrile, polyester, etc. According to people's different grade requirements, it can be spun into All kinds of new textile products meet people's pursuit of "clear, cool and new" fashion requirements for environmental protection and health care. Flame-retardant viscose fiber uses renewable plant cellulose as raw material, flame retardant is added during the production process, and the pre-spinning blending technology is adopted, which not only ensures the fiber texture is soft and smooth, but also realizes permanent flame retardancy, low smoke, and other characteristics. It can be widely used in flame-retardant clothing such as protective clothing, fi...

Problems solved by technology

Although flame-retardant viscose fiber has some properties of viscose fiber, there are differences. The following problems exist in the production process: 1. Flame-retardant viscose fiber is prone to static electricity during the production process, and the phenomenon of winding rollers, top rollers, and aprons Serious, affecting normal production and product quality; 2. The strength is lower than that of cotton fiber, the number of fiber crimps is less, the cohesion is poor, it is easy to slip, it is difficult to card into a web, and the yarn strength is low; 3. The drawing process is easy to block; 4. Roving spun yarn is prone to hard ends
