Abstract
本发明涉及多层复合面料技术领域，具体为一种抗菌防蚊虫涤纶面料及其制备方法。所述制备方法包括以下步骤：将涤纶面料与甲基丙烯酸酐在碱性条件下反应，得到烯基改性涤纶面料；烯基改性涤纶面料与3‑苯基丙烯醛、4‑烯丙基‑2‑甲氧基苯酚、烯基改性纳米氧化锌在紫外光照射条件下，在光引发剂作用下发生乙烯基自由基聚合反应，得到改性涤纶面料；以改性涤纶面料作为外层面料，与内层面料等面积复合，得到抗菌防蚊虫涤纶面料。所述抗菌防蚊虫涤纶面料具有良好的抗菌、防蚊虫、外层拒水、内层快速导湿、高效透汽和去异味性能，且抗菌防蚊虫功效持久释放留存。
The present invention relates to the technical field of multi-layer composite fabrics, specifically to an antibacterial and anti-mosquito polyester fabric and a preparation method thereof. The preparation method comprises the following steps: reacting polyester fabric with methacrylic anhydride under alkaline conditions to obtain an olefin-modified polyester fabric; the olefin-modified polyester fabric and 3-phenyl acrolein, 4-allyl-2-methoxyphenol, and olefin-modified nano zinc oxide undergo vinyl free radical polymerization under ultraviolet light irradiation conditions and under the action of a photoinitiator to obtain a modified polyester fabric; using the modified polyester fabric as an outer layer fabric, and compounding it with an inner layer fabric in equal areas to obtain an antibacterial and anti-mosquito polyester fabric. The antibacterial and anti-mosquito polyester fabric has good antibacterial, anti-mosquito, outer layer water repellent, inner layer rapid moisture conduction, efficient vapor permeability and deodorization performance, and the antibacterial and anti-mosquito effect is released and retained for a long time.
Description
Technical Field
The invention relates to the technical field of multi-layer composite fabrics, in particular to an antibacterial anti-mosquito polyester fabric and a preparation method thereof.
Background
The polyester fabric has the advantages of high strength, good elasticity, good shape retention and the like, and is widely applied to the fields of clothing manufacture and the like. However, if polyester fabric is adopted to prepare summer clothing, bacteria are easy to breed due to high perspiration amount in hot weather, and human health is threatened. In addition, in summer, more mosquitoes exist, and requirements on the mosquito resistance, sweat releasing and moisture permeability of the clothing fabric are also provided. Therefore, the fabric needs to be subjected to antibacterial and anti-mosquito modification treatment.

The microporous polyester filament is made by spinning Polyester (PET) slices, the specification of the prepared filament is 83D/144F, the fineness of single filament is 10 mu m, the spinning process has the parameters of spinning temperature of 295 ℃, side blowing temperature of 25 ℃, humidity of 50% RH, wind speed of 0.3m/S, bundling oil level of 1m, spinning tension of 0.15cN/dtex, draft multiple of 1.1, winding speed of 2500m/min, the polyester slices are purchased from Oya plastic raw materials of Dongguan, model number is FR531, melting point is 250-255 ℃, initial decomposition temperature is 306-316 ℃, the polyester filament is purchased from Kelvin, model number is 75D/144F, nano zinc oxide is purchased from Darcy concentrated nano (model number is N-HQ20W, particle size is 50 nm), polyester is purchased from Darcy industry, model number is S.40S/2.
Test examples
Performance test was performed on the antibacterial and anti-mosquito polyester fabrics prepared in examples 1 to 6 and comparative examples 1 to 2:
(1) Antibacterial property test the antibacterial properties of the polyester fabrics prepared in examples 1-6 and comparative examples 1-2 were tested respectively, the test method was referred to the standard GB/T20944.3-2008, evaluation of antibacterial properties of textiles section 3: vibration method, test results are shown in Table 1:
TABLE 1
(2) Mosquito repellent performance test the polyester fabrics prepared in examples 1-6 and comparative examples 1-2 were tested for their mosquito repellent performance, respectively, with reference to the standard GB/T30126-2013 "detection and evaluation of textile mosquito repellent performance", and the test results are shown in Table 2:
TABLE 2
As can be seen from tables 1 and 2, the polyester fabric prepared by the invention has good antibacterial performance and mosquito-proof performance. The 3-phenyl acrolein and the 4-allyl-2-methoxyphenol are used as aromatic antibacterial and anti-mosquito materials, the nano zinc oxide is used as an inorganic antibacterial material, the antibacterial and anti-mosquito effects of the polyester fabric can be effectively improved by modifying the polyester fabric, the 3-phenyl acrolein, the 4-allyl-2-methoxyphenol and the alkenyl modified nano zinc oxide are connected to polyester molecules through free radical polymerization, the bonding fastness of the nano zinc oxide and the polyester is effectively improved, the problem of reduced antibacterial and anti-mosquito effects caused by high volatility of the 3-phenyl acrolein and the 4-allyl-2-methoxyphenol is avoided, the antibacterial and anti-mosquito effects of the polyester fabric are durable, the antibacterial rate is still more than 90% after 30 times of washing, and the anti-mosquito repellent rate can also reach more than 85%. Compared with the embodiment 1, in the comparative example 1, the polyester fabric is not subjected to alkenyl modification, the 3-phenyl acrolein, the 4-allyl-2-methoxyphenol and the alkenyl modified nano zinc oxide in the composite finishing agent are subjected to polymerization reaction, and the polymerization product can be entangled with polyester molecular chains, but the antibacterial and mosquito-proof components are not connected to the polyester molecules through stable chemical bonds, so that the combination fastness with the polyester fabric is reduced, the antibacterial performance and the mosquito-proof performance are both reduced, the antibacterial and mosquito-proof components are further separated from the polyester fabric after multiple times of washing, and the antibacterial performance and the mosquito-proof performance are both greatly reduced. In comparative example 2, 3-phenyl acrolein, 4-allyl-2-methoxyphenol and nano zinc oxide in the composite finishing agent are adsorbed on the polyester fabric only through adsorption, the surface of the polyester fabric is smooth and flat, the adsorption is weak, and the 3-phenyl acrolein and 4-allyl-2-methoxyphenol have volatility, so that the antibacterial property and the mosquito-repellent property of the modified polyester fabric are obviously reduced, and the reduction range of the antibacterial property and the mosquito-repellent property of the modified polyester fabric is more obvious after multiple times of washing.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
