NOVELTY - Preparing multifunctional wool composite yarn involves preparing melin wool and chitin fiber into wool-chitin mixed fiber by yarn forming process, using nylon 66 as core yarn, twisting the prepared wool-chitin mixed fiber on the core yarn to obtain a first outer coating layer, spraying the graphene-polyvinyl alcohol spinning raw liquid on the first outer coating layer by electrostatic spinning method, twisting orderly alternately cotton fiber and pure wool fiber outside the first outer layer to form a second outer layer to obtain the multifunctional wool composite yarn. USE - Method for preparing multifunctional wool composite yarn. ADVANTAGE - The multifunctional wool composite yarn has anti-shrink, antibacterial and mothproof, anti-static, far infrared, warm and other function, and the preparation method is simple.
