The invention discloses a nylon fabric capable of preventing a pattern from floating and discoloring and a process for manufacturing a sports cap by using the nylon fabric, and relates to the technical field of clothing
textile. The process comprises the following steps: firstly, mixing deionized water with
polyethylene glycol 400 to form a transparent solution, then adding waterborne
polyurethane emulsion, and stirring to obtain a transparent solution; then adding
nano silicon dioxide and modified
nano zinc oxide, carrying out
ultrasonic dispersion, then adding an
ultraviolet light absorber,
epoxidized soybean oil and an organic
silicon defoaming agent, stirring, and filtering to obtain an anti-discoloration
composite coating solution; the preparation method comprises the following steps: pretreating a nylon 66 fabric base material to remove greasy
dirt and floating dust,
drying,
coating the printing surface of the fabric with the obtained
coating liquid by adopting a scraper
coating machine, sequentially pre-
drying, curing, cooling and sealing to obtain the anti-discoloration modified nylon fabric,
cutting the anti-discoloration modified nylon fabric according to the sports cap pattern, printing and
drying the printing area of the cap body
cutting piece, and finally ironing and shaping to obtain the sports cap capable of preventing the pattern from floating and discoloration.
