High-extensibility anti-pilling fiber blended wrap yarn and preparation method thereof

The invention discloses a high-extensibility anti-pilling fiber blended wrap yarn and a preparation method thereof. The high-extensibility anti-pilling fiber blended wrap yarn comprises a spandex core yarn and a wrapping layer wrapping the spandex core yarn, wherein the wrapping layer is formed by blending PTT fibers, soybean fibers, cotton fibers, wool fibers, linen fibers, polyester filament yarns and chinlon yarns. The invention further provides a preparation method for preparing the high-extensibility anti-pilling fiber blended wrap yarn. For the high-extensibility anti-pilling fiber blended wrap yarn prepared by the preparation method provided by the invention, during the blending processing of the natural fibers including wool, linen, and cotton and artificial fibers, the wrapping twisting technology is adopted, so that the cohesive force among the fibers is enhanced, the intrinsic properties of the fibers are effectively protected, the prepared high-extensibility anti-pilling fiber blended wrap yarn has good elastic recovery property, and also has the properties of high strength, high extensibility, high elasticity, and the like, the serious pilling phenomenon and other phenomena of the fibers during the use process are prevented, and the technical problem that the existing blended product can not meet the requirements of the high-grade products is solved.
