Problems solved by technology

[0003] However, the existing antibacterial fibers have a single function and only have antibacterial functions, while the antibacterial active ingredients blended in the antibacterial fibers are easily inactivated or lost after contact with water or other liquids; and most of the antibacterial fibers have poor skin feel, which leads to their application small range

Abstract

The invention discloses a waterproof antibacterial and cooling functional fiber and a preparation method thereof. The waterproof antibacterial and cooling functional fiber is prepared by laminating a waterproof layer and a functional layer in a composite mode, wherein the waterproof layer is a polyurethane film, and the functional layer is prepared by blending, melting and spinning a polymer carrier, functional components, auxiliaries and borneol; and the mass ratio of the components of the functional layer is (300-500): (10-30): (5-15): (1-3). The preparation method of the waterproof antibacterial and cooling functional fiber is simple and easy to implement and low in production cost; in the functional fiber, functional components are selected from plant extract microcapsules and nano-silver microcapsules, and both have an antibacterial effect; besides, a polyurethane film waterproof layer is further arranged, so that the effects of dust prevention, water prevention and pollution prevention can be achieved, bacteria can be effectively prevented from penetrating, and the antibacterial capacity of the fabric is further enhanced; and moreover, borneol is added into the functional layer, so that the functional fiber has a cool and refreshing skin feeling, and the use comfort is high.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, in particular to a waterproof, antibacterial and cooling functional fiber and a preparation method thereof. Background technique [0002] Functional fiber refers to the fiber with some special functions in addition to the existing performance of the fiber, such as conductive fiber, optical fiber, ion exchange fiber, ceramic particle fiber, temperature regulating and heat preservation fiber, biologically active fiber, biological Degradable fiber, elastic fiber, high-emissivity far-infrared fiber, which can produce negative ions, antibacterial fiber, flame-retardant fiber, fragrance fiber, color-changing fiber, radiation-proof fiber, etc. [0003] However, the existing antibacterial fibers have a single function and only have antibacterial functions, while the antibacterial active ingredients blended in the antibacterial fibers are easily inactivated or lost after contact with water or ot...
