Embodiment Construction

[0022] The present invention is a core-spun yarn spun from flame-retardant viscose and aramid fiber blended coated cotton filament, which is made of white flame-retardant viscose fiber 60%-70% and golden yellow aramid fiber F14 fiber 30%-40%. The spun roving is coated with nylon 66 20D filament in the spinning process to make yellow flame-retardant viscose and aramid F14 blended coated nylon 66 filament core-spun yarn; the flame-retardant yarn of the core-spun yarn is The viscose content accounts for 57% of the total weight of the blended yarn, the golden yellow aramid fiber F14 accounts for 30% of the total weight of the blended yarn, and the nylon 66 20D filament accounts for 13% of the total weight of the blended yarn. The thread count is 34. The flame-retardant viscose has a fineness of 4000 Nm, a length of 51mm, and a strength of 1.6CN / dtex; aramid 14 has a fineness of 6000 Nm, a main body length of 38mm, and a strength of 15.38CN / dtex.

Abstract

Disclosed is a covering yarn spun with flame retardant viscose and aramid blended coated cotton fiber and relates to the technical field of textile production. Roving is spun from, by weight, 65% of white flame retardant viscose fiber and 35% of gold aramid F14 fiber, cotton fiber 6620D filament is coated in the spinning process to produce flame retardant viscose and aramid blended coated cotton fiber 66 filament, and the number of yarns is 34 covering yarns. The manufacturing technology includes the steps of picking, carding, drawing, roving, spinning and spooling; a yarn guiding wheel is arranged on a ring spinning table, the filament is on the left-hand side of a drafting floating area, long-fine auxiliary points are added in the spooling process, removal of core leakage yarns and bubble yarns is ensured, and the relative humidity of the manufacturing environment in each process is 53-59%/yarn. The yarn has good moisture absorption and air permeability, good flame retardant performance, comfortable hand feeling and no droplet melting phenomenon.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a core-spun yarn made from flame-retardant viscose and aramid fiber blended covered cotton filament and a manufacturing process thereof. Background technique [0002] With the continuous development of spinning technology and consumers' pursuit of personalized, fashionable and diversified fabrics, the functional requirements of fabrics are also getting higher and higher. Traditional single-structure spinning can no longer meet market demand. For oil refineries, petrochemical firefighting suits, forest firefighting suits and pilot suits, space suits, military and police uniforms, special forces work clothes, etc., the requirements for heat resistance and flame resistance are increasing, and textiles are endowed with more flame retardancy. Performance, ensuring safety and reducing fires are of great significance. At present, most domestic flame-retardant textiles are ma...
