▎ 摘  要

NOVELTY - Fabric treatment process for improving wear resistance of knitted fabrics involves: (1) heating an ethylene glycol solution, cooling, adding polyvinylpyrrolidone to pretreated glycol solution, ultrasonically dissolving, adding silver nitrate, dissolving to get a mixed solution, adding ferric chloride to the pretreated ethylene glycol, dissolving to get a ferric chloride solution, adding to the mixed solution, ultrasonically treating, heating and reacting to obtain a silver nanowire dispersion; (2) immersing knitted fabric in sodium hydroxide solution, taking out, soaking in polyethyleneimine solution, reacting, putting the treated knitted fabric into a mixed dispersion of graphene oxide and silver nanowire, reacting, and reducing to get a pretreated knitted fabric; (3) preparing a modified polyvinyl alcohol; and (4) adding the pretreated knitted fabric to a silane coupling agent solution, soaking, then adding the modified polyvinyl alcohol, stirring, and drying. USE - Fabric treatment process for improving wear resistance of knitted fabrics. ADVANTAGE - The treatment process improves the anti-shearing performance of the knitted fabric and enhances the force between the fibers of the knitted fabric, thus achieving the technical effect of improving the wear resistance of the knitted fabric. DETAILED DESCRIPTION - Fabric treatment process for improving wear resistance of knitted fabrics involves: (1) heating an ethylene glycol solution at 165-175 degrees C for 1-2 hours, cooling to room temperature, adding polyvinylpyrrolidone to pretreated glycol solution, ultrasonically dissolving, adding silver nitrate, ultrasonically dissolving to get a mixed solution, adding ferric chloride to the pretreated ethylene glycol, dissolving to get a ferric chloride solution, adding to the mixed solution, ultrasonically treating, putting into a vacuum oven, heating and reacting for 5-6 hours, taking out, cooling, mixing with the same volume of acetone solution, leaving still overnight, centrifuging with deionized water and absolute ethanol 2-3 times, and ultrasonically dispersing in absolute ethanol to obtain a silver nanowire dispersion; (2) ultrasonically dispersing graphene oxide in deionized water to obtain a graphene oxide dispersion, ultrasonically dispersing with the silver nanowire dispersion to obtain a mixed dispersion, immersing knitted fabric in sodium hydroxide solution, boiling for 1-1.5 hours, taking out, washing with deionized water until it is neutral, drying, soaking in polyethyleneimine solution, reacting at room temperature for 3-4 hours, putting the treated knitted fabric into the mixed dispersion, reacting at room temperature for 30-40 minutes, cleaning and drying, and placing in a vacuum drying oven for thermal reduction to get a pretreated knitted fabric; (3) adding polyvinyl alcohol to deionized water, heating at 80-90 degrees C, stirring to dissolve, heat preserving for 1-2 hours to completely dissolve polyvinyl alcohol, cooling to 65-75 degrees C, adding chloroacetic acid, adjusting the pH to 10-12 with sodium hydroxide, heat preserving for 4-6 hours, then adding hydrochloric acid to adjust the pH to 2-4, cooling, filtering with a cation exchange resin, precipitating the product with ethanol, suction filtering, washing until neutral and drying to obtain a modified polyvinyl alcohol; and (4) adding silane coupling agent to an ethanol solution to obtain a silane coupling agent solution, adding the pretreated knitted fabric to the silane coupling agent solution, soaking for 10-20 minutes, then adding the modified polyvinyl alcohol, stirring at 80-130 rpm for 1-2 hours, taking out the fabric and drying.
