【摘要】 为解决家庭洗护场景中传统防水服装穿着后防水性能下降的修复成本高、能耗大的问题，探索一种基于家用干衣机的织物防水功能整理的新路径。选择未经防水整理的纯尼龙织物为试样，通过构建机外喷涂-家用机内烘干整理体系，系统研究无氟防水剂浓度（SH-A）、防水整理剂附着量（o.w.f）、干衣机烘干时长、织物运动状态及初始含水率对纯尼龙织物防水整理效果的影响。研究发现，在家用干衣机洗护场景下，未经防水整理的纯尼龙织物采用SH-A浓度5%、o.w.f 1.29%、65℃、静态烘干20 min的无氟防水工艺整理后，织物表面沾水等级由2.0级提升至4.5级，静态水接触角达133.2°，且透湿率保持2576±2 g/m~2·d，透气性仅下降1.67%，织物手感无明显改变，表现出良好的防水功能性整理效果。更多还原

【Abstract】 To address the high cost and energy consumption associated with restoring the diminished waterproof performance of traditional waterproof garments after home laundering, this study explores a novel approach for fabric water-repellent functionalization using household tumble dryers. Untreated pure nylon fabric was selected as the test specimen. By establishing a treatment system involving off-machine spraying followed by in-dryer treatment, we systematically investigated the effects of fluorine-free water-repellent agent concentration(SH-A), add-on level(o.w.f), drying duration, fabric movement pattern, and initial moisture content on the water-repellent performance of pure nylon fabric.The study found that within the home laundry context, untreated pure nylon fabric treated with a fluorine-free process(5% SH-A concentration, 1.29% o.w.f, 65℃, static drying for 20 minutes) exhibited significantly enhanced water repellency. The water spray rating improved from Grade 2.0 to Grade 4.5, and the static water contact angle reached 133.2°. Importantly, the moisture vapor transmission rate remained high at 2576±2 g/m~2·d, air permeability decreased by only 1.67%, and fabric hand feel showed no significant alteration. These results demonstrate that this approach achieves excellent water-repellent functionalization suitable for household application.更多还原
