The Microcomputer Control Ring Spun Slub Yarn Production Optimization Of Design And Performance Analysis

Slubby yarn, which is a kind of slub yarn, has been widely used in textile fields, such as Garment, Decoration and Tourism, and has occupied some shares in market relying on its distinctive structure, rich colors and high added-value. We have engaged in slubby yam research much earlier, but only remained on more simple machine-reforming for a long time. Product quality fluctuates greatly, and there arise phenomena of cutting and parameter unaccuration of slubby yarn research more earlier, but only remained on more simple machine-reforming for a long time. Product quality fluctuates greatly, and there arise phenomena of cutting and parameter unaccuracy of slubby yarn in spinning, even its automation and accuration are much lower.Through the summary and comparison of spinning all kinds of slubby yarns domestic, this topic makes the optimum program on spinning it on ring spinning frame, that is using frequency electric machinery and single blade computer controller. Also the topic makes design and research on the reforming and installing spinning frame, and on some procedures of controlling system. And with the aid of computer Microsoft on yarn figure display, which makes comparison between accurate diameter and designed diameter by testing base-yarn and slubby yarn, and through a great deal of comparison tests, it proves the program reasonable and workable.As for slubby yarn texture feature, which causes difficulty on spinning and weaving, therefore through tests and analyses on twist, additional-twist, strength, the topic mainly researches slubby yarn three basis parameters, i.e. slub distance, slub length and finest of the nubby-yarn affecting the above-mentioned parameters; analyzes affecting slubby yarn twist main factors and the rupture mechanism; draws up the optimum technology program; provided certain theorized foundation to meet the quality standardization of slubby yarn's every item and spinning and weaving. In addition, by means of computer simulator and sample test weaving, it makes fabric simulate and weave; analyzes all kinds of weave structure and different arrangement of wrap and woof affecting the face effect; provides visible reference for processing garments of different styles. The research on this topic provides the technological basis to the development of slubby yarn and its products with high quality and magnificent. It also speeds and enlarges the application of slubby yarn. And promotes the spinning technology of slubby yarn more mature.
