USE - The method is useful for preparing warp-knitted hydrophobic Terylene (Synthetic polyester fiber) fabric. ADVANTAGE - The method: involves modifying the surface of nano-zinc oxide and adding siloxane-alkylated PDA and zinc ethoxide to improve the uniform distribution of nano-zinc oxide inside the chemical fiber when preparing chemical fiber filaments from the melt, has long-lasting antibacterial properties; uses graphene material, which improves wear resistance; utilizes the superfine Terylene (Synthetic polyester fiber) multifilament, which has soft hand feeling and hydrophobic function after heating. DETAILED DESCRIPTION - Preparing warp-knitted hydrophobic Terylene(Synthetic polyester fiber) fabric, comprises (1) uniformly mixing the powder surface modifying agent with the nano-zinc oxide, placing in deionized water, irradiating with UV rays for 10-15 minutes and drying to prepare surface-modified nano-zinc oxide; (2) drying the Terylene(Synthetic polyester fiber) chips and grinding them to obtain a mixed powder; adding surface-modified nano-zinc oxide, nano-scale graphene particle material, ethylene acrylate copolymer, siloxane-alkylated polydopamine (PDA) and zinc ethoxide into Terylene(Synthetic polyester fiber) powder, adding it to a twin-screw extruder to extrude and granulating to obtain antibacterial masterbatch; (3) uniformly mixing antibacterial and wear-resistant masterbatches, Terylene(Synthetic polyester fiber) chips, hyperbranched polymers and bisamide sulfonate surfactants and melting them, and stirring for 10-15 minutes; sequentially passing through the pre-filter assembly and the metering pump, spinning using spinning box to obtain superfine Terylene(Synthetic polyester fiber) multifilament 288F, where the diameter of each single filament is less than 0.1D; (4) weaving grey cloth on the warp knitting machine, the grey cloth comprises a bottom comb and a face comb, the bottom comb, the surface comb is fully woven, the yarn comb is made of 45D Terylene(Synthetic polyester fiber) elastic yarn, the used padding yarn number is 2-3/1 -0 //, the surface comb adopts the yarn-fine Terylene(Synthetic polyester fiber) composite yarn prepared in the previous step; the used padding yarn number is 1-0/5-6 //; (5) the grey cloth prepared in the last step under the polyester melting point under the temperature condition of the grey cloth shaping, then napping machine, according to the design format and napping length of the fabric, by a plurality of parallel steel needle napping machine repeatedly for kneading the surface of the grey cloth, the fabric single surface floss; then the size of the flannel is stabilized by the shaping technique; (6) soaking the fuzz fabric prepared in the previous step, adding to the softening agent, part of levelling agent and expanding agent into the working liquid, and adding pH regulator to adjust the working liquid pH to 4.5-5, heating to 45℃, adding disperse dye and residual levelling agent to prepare dyeing liquid, and maintaining for 10-15 minutes, then heating and dyeing; where heating the working liquid to 45℃ at heating speed of 2.5 ℃/minute; the heating and dyeing adopts sectional heating including controlling the dyeing liquid to heating to 100 ℃ at a rate of 1.5 ℃/minutes and maintaining for 5-10 minutes, then heating to 115 ℃ at a rate of 0.6℃/minute and maintaining for 5-10 minutes, at last heating to 135℃ at a rate of 1.5℃/minutes and maintaining the temperature and maintaining for 25-30 minutes; the working liquid is heated to 43℃ and then linearly adding disperse dye and residual levelling agent, the linear addition time of the disperse dye and the rest levelling agent is 20 minutes; the levelling agent is PRDN, the sum of the dosage of the part levelling agent and the rest levelling agent is 2-4 g/l, the mass ratio of the part levelling agent and the rest levelling agent is 2:1; (7) spraying water-repellent agent on the fabric after dyeing, then ironing the velvet surface at a certain temperature of the ironing roller, and then trimming down to make it have a certain height of the floss.
