Abstract

The invention discloses a preparation method of multifunctional wool composite yarn. The preparation method comprises the following steps of S1, preparing wool/chitin mixed fibers from merino wool and chitin fibers through a yarn forming process; and S2, taking nylon 66 as core yarn, twisting the wool/chitin mixed fibers prepared in the step S1 on the core yarn to form a first outer wrapping layer, then spraying and spinning a graphene/polyvinyl alcohol spinning solution on the first outer wrapping layer through an electrostatic spinning method, and sequentially and alternately twisting cotton fibers and pure wool fibers on the outer side of the first outer wrapping layer to form a second outer wrapping layer, so as to obtain the multifunctional wool composite yarn. The multifunctional wool composite yarn has multiple functions of shrink prevention, antibiosis, moth prevention, static resistance, far infrared radiation, heat preservation and the like, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of yarn production, in particular to a multifunctional wool composite yarn and a preparation method thereof. Background technique [0002] With the continuous development of science and technology, people's requirements for living standards are getting higher and higher, while the awareness of environmental protection is also increasing, and the functionality of clothing is also diversified. Due to the excellent warmth, comfort, softness and other properties of wool itself, it is inseparable from people's lives, but its own characteristics have some unavoidable defects. [0003] Chinese invention patent CN110117856 A (disclosure date August 13, 2019) discloses Tencel wool blended yarn, which is prepared by blending wool fiber and Tencel fiber. The blended yarn has low production cost, but does not solve the problem of woolworm The problem of moth, followed by a high proportion of wool yarn will shrink and p...
