Problems solved by technology

[0003] At present, the treatment method of anti-mosquito fabric is mainly made by physical impregnation with mosquito repellent, but the mosquito repellent deposited on the fabric volatilizes quickly, is not resistant to washing, and has a short duration
The existing fragrance-containing fabrics are mainly treated with essence microcapsule finishing liquid by dipping, but the general fragrance microcapsules can only be attached to the fiber surface, are easily washed off, the fragrance stability and persistence are poor, and the fabric cannot last for a long time.

Abstract

The invention discloses a novel anti-mosquito fabric with long-lasting fragrance and a preparation method thereof. The preparation method comprises the following steps: subjecting cotton fibers and beta-damascenone to free radical-induced double bond polymerization so as to prepare fragrant fibers; preparing a lemongrass extract-lavender essence nanocapsule from lemongrass extract, lavender essence, gelatin, an emulsifier, chitosan and sodium alginate, and chemically loading the lemongrass extract-lavender essence nanocapsule into a micropore through an amination reaction of the cyano group ofmicroporous polyacrylonitrile fibers with the amino group of chitosan so as to prepare lemongrass extract-lavender essence fibers; then blending the fragrant fibers and the lemongrass extract-lavender essence fibers to form a fabric; and finally, subjecting the fabric to hydrophilic silicone oil finishing so as to obtain the anti-mosquito fabric with long-lasting fragrance. The anti-mosquito fabric with long-lasting fragrance of the invention has the fruity, green, floral, woody and berry fragrance of beta-damascenone and the fragrance of lavender, and also has anti-mosquito effect; and the fragrance is continuously and slowly released, and the anti-mosquito effect is long-lasting.

Description

technical field [0001] The invention belongs to the technical field of fabric processing. More specifically, it relates to a novel anti-mosquito long-lasting fragrance fabric and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for clothing are getting higher and higher. They not only pursue comfort, sweat absorption, and ventilation, but also require multiple functions such as fragrance and anti-mosquito. The fabric with anti-mosquito function can avoid directly applying mosquito repellent liquid on the skin, and can effectively prevent mosquito bites; the fabric with fragrance can relieve stress, relax emotions, and stimulate the brain to produce excitement. Therefore, fabrics with mosquito repellent and fragrance are very popular. [0003] At present, the treatment method of anti-mosquito fabrics is mainly to use mosquito repellent through physical impregnation, but the mosqui...
