Method for producing 40s Siro spun yarns by using Antifrayon fire-retardant fibers

Abstract

The invention relates to a method for producing 40s Siro spun yarns by using Antifrayon fire-retardant fibers. A required cone yarn is produced by performing blowing, cotton carding and tertiary drawing on the Antifrayon fire-retardant fibers and performing roving, spinning and spooling procedures. In the blowing procedure, flock powder and static electricity are reduced, and lap licking is prevented; the tertiary drawing is adopted, so that the weight irregularity of silvers is lowered; in the roving procedure, the fuzzing of cotton silvers and roving silvers is prevented, and the smooth finish of a spinning channel and each component is enhanced; a Siro spinning device is arranged on a spinning machine; and an electric clearing procedure is adopted preferably in the spooling procedure. The Siro spun yarns produced with the method have better quality and superior resultant yarn hairness, evenness and force index to ring yarn, and are high-quality materials for high-end knitted underwear, clothes and bed articles; and the Siro spun yarn has the advantages of compacter structure, small quantity of yarn hairness, smoother appearance, higher wear resistance, soft handfeel, high air permeability, high drapability, high wrinkle resistance and high fuzziness and pilling resistance, and can be used for replacing threads. A knitted fabric can be applied to various fire-retardant clothes and fire-retardant decorating materials.

Description

technical field [0001] The invention relates to a kind of flame-retardant fiber-Amphora flame-retardant fiber to produce 40 s The method of siro spinning. Background technique [0002] Amphora flame retardant fiber is a high-tech flame retardant fiber produced by Shandong Hailong Co., Ltd. This product uses renewable plant cellulose as raw material, and adds a self-developed phosphorus flame retardant during the production process. The blending technology added before spinning not only ensures the softness and smoothness of the fiber texture, but also realizes the characteristics of permanent flame retardancy, low smoke and so on. It can be widely used in flame-retardant clothing such as protective clothing, fire-fighting clothing, and military uniforms, and flame-retardant decorative materials for indoors, automobiles, airplanes, and public places, etc. Amphora flame retardant fiber has the following characteristics: 1. High flame retardancy. Amphora flame-retardant fibe...

AI Technical Summary

Problems solved by technology

Although Amphora flame-retardant fiber is a high-tech flame-retardant viscose fiber for textiles, it has some properties of viscose fiber, but there are differences. The following problems exist in the production process: 1. The flame-retardant fiber is in the production process Static electricity is easily generated in the middle, and the phenomenon of winding rollers, top rollers and aprons is serious, which affects normal production and product quality; 2. The strength is lower than that of cotton fibers, the number of fiber curls is small, the cohesion is poor, it is easy to slip, and it is difficult to card into a web. Low yarn strength; 3. The drawing process is easy to block; 4. The roving and spun yarn are easy to produce hard ends
