▎ 摘  要

NOVELTY - The warp knitted fabric has a front comb yarn and a back comb yarn in a mass ratio of (50-80):(18-58). The front comb yarn is a synthetic yarn finished by an antistatic liquid. The back comb yarn is spandex core-spun yarn. The antistatic liquid is mainly prepared from raw materials comprising 50-60 pts. wt. water, 1-2 pts. wt. an antistatic oil agent, 5-10 pts. wt. a smoothing agent, 5-8 pts. wt. an emulsifier, 2-3 pts .wt. sodium chloride and 1-2 pts .wt. graphene oxide. The emulsifier is composed of polyoxyethylene sorbitan monostearate and fatty alcohol polyoxypropylene polyoxyethylene ether. A warp knit fabric according to claim 1 wherein: the smoothing agent is castor oil. USE - Warp knitted fabric. ADVANTAGE - The warp knitting fabric adopts thinner preceding carding yarn to knit to make the warp knitting fabric comparatively soft. The warp knitting fabric prepared by the method is strong in antistatic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of processing a warp knitting fabric, which involves: mixing the above raw materials to obtain the antistatic liquid; dipping the synthetic yarn in antistatic liquid to obtain the finished front combing yarn; knitting the back comb yarns and the finished front comb yarns into a fabric; and immersing the fabric in an impregnation liquid to obtain a warp knitted fabric, where the impregnation liquid comprises 50-60 pts. wt. water, 1-2 pts. wt. a dispersing agent, 8-10 pts. wt. an antistatic agent, 1-2 pts .wt. an adhesive and 8-10 parts of activated carbon, the antistatic agent is at least two of modified starch, an antistatic agent and a carbon nano tube, and the modified starch is obtained by melting and mixing an intermediate prepared from polyethylene wax, diethanol amine and stearic acid, starch, water and acrylic acid, cooling and pelletizing.
