摘　　要：为提高羊毛/羊绒(60/40)织物自清洁能力,降低织物因清洗而造成毡缩变形等不良影响,采用常压等离子体对羊毛/羊绒混纺织物表面进行预处理,再使用微纳米级乙酰丙酮锆及聚二甲基硅氧烷自制无氟环保型毛织物拒水剂对织物进行静电喷雾疏水处理。通过分析织物等离子体处理前后静态接触角变化及红外测试结果,发现最佳等离子体处理参数以及对织物毡缩性能的影响。比较等离子体处理前后及等离子体预处理再进行疏水整理织物的外貌形态、静态接触角、透湿透气性、防紫外线性能差异。结果表明:羊毛/羊绒织物经等离子体预处理再进行静电喷涂具有优异的疏水性能,静态接触角提高至152°,达到超疏水临界值,织物透湿透气性仅分别降低2. 98%、1. 65%,毡缩性下降4. 61%,此外,该方法辅助提高了织物14. 14%的紫外线防护系数。In order to improve the self-cleaning ability of wool/cashmere (60/40) fabrics and reduce the adverse effects of fabric shrinkage caused by cleaning, the fabric surface was pretreated by atmospheric pressure plasma. Then, the micro/zirconium nano-sized acetylacetonate and polydimethylsiloxane were adopted to prepare the fluorine free environment-friendly fabric water repellent agent for electrostatic spraying and hydrophobic treatment. By analyzing the static contact angle change and the infrared test results of original sample and plasma-treaded sample, the best plasma treatment parameters and the effect of fabric shrinkage were found. The original sample, plasma-treaded sample and plasma-treaded with hydrophobically treated sample were compared in the morphology, static contact angle, moisture permeability and ultraviolet resistance. The study reveals that the hydrophobic sample finished by electrostatic spraying after plasma treatment exhibits excellent hydrophobicity. The static contact angle increases to 152°, which reaches the super hydrophobic critical value. The moisture permeability and air permeability of the fabric decrease by only 2.98% and 1.65%, and the shrinkage of the fabric decreases by 4.61%. Moreover,this method assists in increasing the ultraviolet protection of the fabric by 14.14%.
