Problems solved by technology

But in this way, the anti-mosquito agent in the core layer is completely covered by the cortical fiber, which limits the diffusion of the anti-mosquito agent to the fiber surface to a certain extent, thereby reducing the actual anti-mosquito effect of the fiber.
By increasing the content of anti-mosquito agent in the core layer, the anti-mosquito effect can be improved to some extent, but on the one hand, the fiber cost is greatly increased, on the other hand, the spinnability of the fiber is reduced and the production technology is quite high.

Abstract

The invention provides skin core porous type anti-mosquito antibacterial fiber. The skin core porous type anti-mosquito antibacterial fiber comprises a composite structure of a core layer and a skin layer; nanometer holes are uniformly distributed in the skin layer uniformly and the diameter of each hole is below 400 nm; the core layer mainly comprises polymer resin and an anti-mosquito agent; andthe skin layer mainly comprises a graphene material and polymer resin. A preparation method comprises the following steps: (A) blending the graphene material, insoluble salt of calcium and / or bariumand polymer resin to serve as the skin layer, blending the anti-mosquito agent and the polymer resin to serve as the core layer, compounding the components of the skin layer and the core layer to perform melt spinning, and enhancing elasticity to obtain composite fiber; and (B) performing acid treatment on the surface of the composite fiber to prepare holes, thereby obtaining the skin core poroustype anti-mosquito antibacterial fiber. According to the embodiment of the invention, nanometer holes are distributed in the surface layer of the fiber, the anti-mosquito agent of the core layer can slowly release outwards through the holes, and a durable anti-mosquito effect is given to the fiber. The graphene added in the skin layer can give high antibacterial and bacteriostatic effects to the fiber.

Description

technical field [0001] The invention relates to the field of fiber processing and preparation, in particular to a skin-core porous anti-mosquito and antibacterial fiber and a preparation method thereof. Background technique [0002] Mosquitoes are ubiquitous in human living places and have brought great troubles to human life. Mosquitoes bite human skin and can transmit diseases through blood. Especially in relatively backward and poor African regions, mosquito bites seriously threaten human health. Although people can use mosquito nets, the effect is not satisfactory. People are still attacked by mosquitoes and die from malaria. At present, the application of fiber science to develop a fiber and fabric with good anti-mosquito effect is of great significance to the protection of human health and life. [0003] Chinese patent CN 100350085C relates to a mosquito repellent twisted silk and its manufacturing method. It adopts a skin-core structure, the cortex material is all l...
