Abstract

The invention discloses a method for processing an outdoor chinlon fabric ultraviolet-proof coating and relates to the technical field of functional fabrics. The method includes a step (1) of pretreating a chinlon fabric; a step (2) of preparing an ultraviolet-proof treating fluid; a step (3) of padding the chinlon fabric; and a step (4) of fixing the ultraviolet-proof coating. According to the processing method, after the chinlon fabric is treated, the ultraviolet resistance of the chinlon fabric can be remarkably improved, the UVA transmissivity and UVB transmissivity are lower than 4%, andthe UPF is larger than 30; the tidied chinlon fabric has good stability in ultraviolet-proof effect, and high ultraviolet resistance can still be maintained after washing for 50 times; the use safetyis higher, no adverse effect is caused to the human body after long-term use, and the problem of poisoning in use of conventional chemical ultraviolet absorbers is solved.

Description

Technical field: [0001] The invention relates to the technical field of functional fabrics, in particular to a method for processing an anti-ultraviolet coating of outdoor nylon fabrics. Background technique: [0002] Nylon, commonly known as nylon, also known as polyamide fiber, has the advantages of high strength, high wear resistance, strong chemical resistance, good deformation resistance and aging resistance, and the disadvantage is that it feels hard. Nylon is the most common outdoor textile material, widely used in backpacks, sleeping bags, clothing, tents and other processing. [0003] Since the outdoor nylon fabric is in the outdoor environment for a long time, the requirements for its UV protection are very high, especially when it is used in outdoor clothing processing. At present, only relying on the anti-ultraviolet performance of nylon fabric itself can no longer meet the anti-ultraviolet requirements of outdoor clothing. Therefore, it is necessary to add a s...
