Abstract

The invention provides a special skeleton composite new material yarn and a preparation method therefor. The yarn comprises outer wrapping fibers and core yarn fibers. The yarn is characterized in that the yarn evenness CV is 8.1-9.6%, the number of thin segments in one thousand meters is 0-1, the number of nubs in one thousand meters is 3-6, and the number of neps in one thousand meters is 16-25. The invention also provides a preparation method for the special skeleton composite new material yarn. The method comprises an outer wrapping fiber raw material pretreatment step of performing spraying pretreatment on outer wrapping fiber raw materials by using a composite oil agent. The composite oil agent comprises, in weight percentage, 4-6% of silica sol, 3-5% of glycerinum, 18-20% of an antistatic agent, 15-17% of peregal, and 51-57% of water, wherein the temperature of water is 45-50 DEG C. The prepared skeleton composite new material yarn is characterized by constant wrapping tension maintenance and favorable wrapping, and is free of such quality problems as naked threads, hollow yarns and thread loop noses.

Description

technical field [0001] The invention relates to a special skeleton composite new material yarn and a production method thereof, belonging to the technical field of ring spinning. Background technique [0002] With the replacement of functional fibers, protective clothing continues to develop in the direction of multi-functionality, compounding and comfort. Although the market's requirements for protective clothing are increasingly demanding, it is difficult to meet the requirements of protective clothing due to the uniqueness of various fibers. The development of core-spun technology has brought development opportunities to occupational protective clothing, but the quality stability of core-spun products is poor at present, and the depth and breadth of product applications are far from enough. Therefore, the development of functional core-spun products and the quality of core-spun products This problem has become a new research topic. This invention is entrusted by the Chin...
