Multifunctional alloy filament wrap yarn and preparation method and application thereof

The invention provides a multifunctional alloy filament wrap yarn and a preparation method and application thereof, and relates to the technical field of textile materials. According to the invention, alloy is sequentially subjected to wire drawing and softening heat treatment to obtain alloy metal fiber filaments with spinnability; the alloy metal fiber filament is used as a core yarn, a yarn is used as a covering yarn, and the multifunctional alloy filament covering yarn capable of being used for spinning is obtained through covering. The multifunctional alloy filament wrap yarn prepared by the invention has the functions of sterilization, deodorization, electromagnetic radiation prevention and static electricity removal, and can achieve the same effect as a nano coating and a chemical preparation. 本发明提供了一种多功能合金长丝包覆纱及其制备方法和应用，涉及纺织材料技术领域。本发明通过将合金依次进行拉丝和软化热处理，得到具有可纺性的合金金属纤维长丝；本发明以所述合金金属纤维长丝作为芯线，以纱线作为包覆线，进行包覆，得到可用于纺织的多功能合金长丝包覆纱。本发明制备的多功能合金长丝包覆纱具有杀菌除臭、防电磁辐射、除静电的功能，并能达到和纳米涂层、化工制剂同等的效果。
