NOVELTY - Producing water-absorbent terylene warp knitted fabric involves taking water-absorbing modifier, polyester-polyester slice as raw material, warping is carried out by using water-absorbing terylene as raw material, warp knitting, primary shaping and shaping are used for preparing water-absorbing terylene warp knitted fabric. The water-absorbing terylene is prepared by mixing the graphene oxide with de-ionized water phase, then adding sodium hydroxide with concentration of 20 % toadjust the pH to 6.5-7.5, adding acrylic acid, Tween (RTM: nonionic surfactant) 80, trimethyl silicon methacrylate; titanium dioxide, andperforming ultrasonic dispersion, then addingammonium persulfate and stirring uniformly, then adding silicon melting coupling agent, and thenconcentrating to remove water, then granulating, preparing water-absorbing modifier particles. The water-absorbent modifier particles, sodium carboxymethyl cellulose and polyester chips are melt-spun. USE - Method for producing water-absorbent terylene warp knitted fabric. ADVANTAGE - The prepared warp-knitted fabric has been greatly improved in terms of water absorption capacity, which can make the application range of the warp-knitted fabric wider, under the premise of ensuring good strength, the water absorption rate can be greatly increased. DETAILED DESCRIPTION - Producing water-absorbent terylene warp knitted fabric involves taking water-absorbing modifier, polyester-polyester slice as raw material, warping is carried out by using water-absorbing terylene as raw material, warp knitting, primary shaping and shaping are used for preparing water-absorbing terylene warp knitted fabric. The water-absorbing terylene is prepared by mixing the graphene oxide with de-ionized water phase, then adding sodium hydroxide with concentration of 20 % toadjust the pH to 6.5-7.5, adding acrylic acid, Tween (RTM: nonionic surfactant) 80, trimethyl silicon methacrylate; titanium dioxide, andperforming ultrasonic dispersion, then addingammonium persulfate and stirring uniformly, then adding silicon melting coupling agent, and thenconcentrating to remove water, then granulating, preparing water-absorbing modifier particles. The water-absorbent modifier particles, sodium carboxymethyl cellulose and polyester chips are melt-spun to prepare water-absorbent polyester with a sheath-core structure, which is first treated with a sodium bisulfite solution with a concentration of 5-10%, and then passing through a water bath and ethanol in turn. The water-absorbent polyester includes a skin portion and a core portion. The core portion is polyester fiber. The mass fraction of water-absorbent modifier particles in the skin is 5-10%.
