High-strength wear-resistant nanofiber composite yarn and preparation method thereof

Abstract

The invention relates to a high-strength wear-resistant nanofiber composite yarn, which comprises a core yarn and a fasciated yarn, wherein an oriented nanofiber yarn or a nanofiber / filament covering yarn is adopted as the core yarn; and a water-soluble or alkali-soluble chemical fiber filament is adopted as the fasciated yarn. When the nanofiber covering yarn is used as the core yarn, a water-soluble vinylon or alkali-soluble polyester or other filament or yarn can be adopted as a core material, and a biocompatible or common filament or yarn can be also used as the core material. The preparation method of the high-strength wear-resistant nanofiber composite yarn comprises the following step of: adopting the high-strength nanofiber yarn or the nanofiber / filament covering yarn as the core yarn; winding the water-soluble vinylon or alkali-soluble polyester or other filament on the core yarn by using a hollow ingot form a composite yarn, wherein the nanofiber can be favorably cladded just by one or twice winding, therefore the composite yarn is favorable in strength and wear resistance for subsequent weaving and the fasciated yarn and the core yarn can be removed through posttreatment after weaving is finished. The composite yarn disclosed by the invention can be weaved and can be also prepared into various structures of materials, composite materials and materials with specific functions through combination and functionalization.

Description

technical field [0001] The invention belongs to the textile field and relates to a high-strength wear-resistant nanofiber composite yarn and a preparation method thereof. Background technique [0002] Electrospinning is a simple and economical method to prepare nanofibers. Compared with the traditional spinning method, electrospinning has two remarkable features, one is that the drafting force adopts electric field force, and the other is that the fibers are finely spun (50-1000nm). The fiber web prepared by electrospinning has the characteristics of small pores, high porosity, and large specific surface area, and can be used for filter materials, barrier and separation membranes, biomedical materials, and functional materials. Electrospun nanofibers have a microscopic structure similar to natural extracellular matrix, so that the prepared scaffold can mimic the structural characteristics of natural extracellular matrix; its extremely high specific surface area also provide...
