【Abstract】 By optimizing the synthesis process parameters such as reaction temperature of 75 ℃, reaction time of 4 h, monomer mass fraction of 30%, emulsifier mass fraction of 6%, and initiator mass fraction of 0.6%, the acrylate-based waterproof and oil-repellent finishing agent was polymerized via emulsion polymerization. The finishing agent exhibited excellent stability and demonstrated superior waterproof and oil-repellent performance on polyester fabrics, achieving a static water contact angle of 121° and preventing oil drop penetration within 30 s. For knitted shoe upper fabrics, a padding-and-baking process was adopted, silver ions were incorporated into the prepared emulsion, and the finishing process was optimized as follows: raw fabric sample of knitted upper → seven dips and seven rolls → a prepared 300 g/L fluorine-free finishing agent → immersion for 30 min → pre-baking at 70 ℃ for 90 s → baking at 160 ℃ for 3 min. The vertical pneumatic electric rolling mill was operated at 0.2 MPa pressure and a speed of 3 m/min. The treated knitted shoe upper achieved a waterproof level of 5 with a waterproof surface wetting time exceeding 300 s and antibacterial efficiency exceeding 99%.更多还原
