Description

Wormwood mosquito-proof ultraviolet-resistant chinlon Technical Field The invention relates to the technical field of functional chemical fibers, in particular to a mugwort mosquito-proof ultraviolet-resistant nylon. Background The nylon has excellent mechanical strength, wear resistance, hygroscopicity and dyeing property, and is the synthetic fiber with the widest application in the fields of clothing, home textile and outdoor protection. Along with the continuous improvement of the requirements of functional textiles, nylon fibers with long-acting mosquito repelling, ultraviolet resistance and ageing resistance are an important direction for the advanced development of industries. In summer and outdoor environment, the traditional mosquito repellent preparation has the problems of short time effect, easy volatilization, possible skin irritation and the like. The mosquito repellent function is integrated in the fiber, long-acting protection is realized through the controlled release of the active components, and the mosquito repellent function becomes an important research and development direction of the functional fiber. At present, the mosquito-repellent fiber is mostly prepared by adopting a post-finishing coating or dipping process, and has the problems of low adhesion fastness of functional components, poor washing resistance, easy migration and precipitation due to friction, influence on the original hand feeling and air permeability of the fabric and the like, so that the durability requirement of the outdoor textile is difficult to meet. A master batch blending melt spinning method is adopted to uniformly disperse functional components in a fiber matrix, and is a main mode for improving mosquito-repellent durability, for example, chinese patent CN102618959A discloses a mosquito-repellent nylon 6 fiber and a preparation method thereof, firstly, after attapulgite is used for adsorbing mosquito-repellent ester, additives and nylon 6 resin are added, the mixture is extruded and granulated in a double-screw extruder to prepare the mosquito-repellent nylon 6 master batch, the weight percentage formula of the mosquito-repellent nylon 6 master batch is 60-70% of fiber-grade nylon 6 resin, 15-30% of attapulgite, 0.1-1% of an antioxidant composition of MD697 and one of hindered phenols, phosphite and thiodipropionate antioxidants, 0.1-15% of light stabilizer and 5-15% of mosquito-repellent ester, and then the nylon 6 chip and the above-mentioned nylon 6 master batch are subjected to blending spinning according to the weight ratio of 80-90:10-20, but the mosquito-repellent nylon 6 fiber still has the defects of only adding single chemical mosquito-repellent ester, being single in function and environment-friendly, being poor in environment-friendly, the compatibility of the fiber and easy to lead to poor dispersion performance, the nylon 6 fiber to poor in ultraviolet radiation resistance, and poor anti-aging performance, and poor ultraviolet radiation resistance, and poor performance, and long-term degradation resistance, and poor performance, and anti-aging performance, and resistance.
