What is false draw texturing yarn(DTY)? What types does it have?
What is draw texturing yarn? What types does it have? Synthetic fibers such
as polyester and nylon for false twist have the characteristics of
thermoplasticity. The fiber is twisted and crimped and deformed by heat. The
twisted and crimped fiber is fixed to obtain a fluffy, elastic, and twist-free
elastic yarn. It is slightly twisted without twist and has good elasticity, so
it is called false twisted stretch yarn.
There are five main types of draw texturing yarn, its abbreviation is DTY yarn.
(1)-General false twisted yarn: that is, the fiber must be untwisted after twisting, and the yarn maintains the bulkiness of the twisted state, but has no twist. The traditional processing method adopts the above three-step method, and is currently completed in one step on a false twist stretch yarn machine. The fibers have better properties and can develop better crepe effect torsion and elasticity, and thus can develop crepe fabrics and elastic fabrics with better crepe effect.
(1) Real twisted false twisted yarn: in order to make the product comfortable due to the fluffy false twisted elastic yarn, and have a better bunching property, so that the fabric has a good weaving effect, people will A certain twist is added to the silk machine to form a real twist false twisted elastic yarn. At present, the real twisted false twisted elastic yarn has been finished on a one-step texturing machine.
(3) Slub yarn: False twisted elastic yarn is mixed with other monofilaments and twisted. Because the gap is over fed, the mixed fiber surface has regular bamboo segments, and this bamboo segment is completely covered by the skin. Instead of twisting the bamboo segment and the core wire side by side, this is the slub yarn developed on the market ... At present, there are more than 10 kinds of varieties. For example, polyester FDYY (full-stretch yarn) is leather yarn, and white polyester FDY is core yarn, which mainly reflects the convex effect of the bamboo section. The common specifications are 240dtex / 60f. . Polyester yarns are leather yarns and white polyester FDY as core yarns. Polyester yarns mainly reflect the cationic color absorption effect of bamboo. The common specifications are 222dtex / 54f and 226dtex / 60f. White polyester FDY is leather yarn and white nylon FDY is core yarn, which mainly reflects the white effect of bamboo segments. The common specifications are 222dtex / 56f (200 denier / 56f) and 222dte10f (200 denier / 60f). The knot length of knot yarn is 1-15cm, which can be adjusted within 10-100 per meter. The tightness of the knot can be slipped due to snug tightness or slippage due to looser snugness.
