Embodiment 1

[0016] Embodiment one: get U.S. DuPont company aramid fiber (commercial brand: M100) fabric 100KG, in the high-temperature high-pressure dyeing machine commonly used, clean the oil stain on the fabric surface with the nonionic surfactant of 0.5g / l (commonly referred to as pretreatment ), after the pretreatment, add 20KG anti-aging reagent emulsion to the dyeing solution, slowly raise the temperature to 120°C, and dye for 1.5h. After dyeing, it is washed with 0.1g / l surfactant, and after drying, a flame-retardant fabric with excellent anti-aging performance can be obtained. The comparison of the mechanical properties of the fabric before and after anti-aging treatment is shown in Table 1.

Abstract

The invention relates to an anti-light ageing finishing method of aromatic polyamidoester fibre cloth, and the method comprises processing aromatic polyamidoester fibre cloth in anti-light ageing finishing agent for 90+-5 minutes under the temperature of 120+-2 DEG C, washing cloth with surface active agent and drying after finishing, wherein the mass ratio of aromatic polyamidoester fibre cloth and anti-light ageing finishing agent is 100:20+-1, the anti-light ageing finishing agent is emulsion whose solid content is 20+-1% and is formed by N,N-diethylm-toluidine, alkyl phenol polyoxyethylene ether and alkylbenzene polyoxyethylene ether which are dissolved in water according to the mass ration which is 80+-0.5:15+-0.5:5+-0.5. The method can lead the intensity after aramid fiber cloth is aged through ultraviolet to reach 87%, and the method has no influence to the physical and chemical property of aramid fiber cloth, and the mechanical property after finishing has no loss. The method of the invention has the advantages of simple technique, strong operability, convenient operation and low production cost.

Description

technical field [0001] The invention relates to an anti-light aging finishing method of aromatic polyamide fiber fabric. Background technique [0002] The aromatic polyamide fiber (known as aramid fiber) first developed by DuPont in the United States is an organic fiber whose macromolecular chain is composed of aromatic rings and amide bonds. It has high strength, high modulus, and low density. Performance, its strength is higher than that of carbon fiber, its quality is lighter than that of glass fiber and carbon fiber, its thermal expansion coefficient is low, and its fatigue resistance is good. Therefore, it is widely used in aerospace, national defense, automobile industry, protective clothing, sports equipment and so on. However, aramid materials are prone to photoaging degradation under ultraviolet radiation, resulting in a gradual decline in the mechanical properties of the product, resulting in brittleness, cracking, and yellowing, and even damage, making it unusabl...
