摘要： 为制备具有疏水拒油、抗紫外线及隔热的多功能棉织物,将氟硅烷三乙氧基-1H,1H,2H,2H-十三氟代正辛基硅烷(POTS)与铯钨青铜纳米粒子(Cs_0.33WO₃NPs)在乙醇溶液中共混,采用“一步法”浸轧-烘干整理到棉织物上,并探讨棉织物负载的Cs_0.33WO₃NPs质量分数对棉织物抗紫外、隔热性的影响。结果表明:POTS质量分数2.3%,Cs_0.33WO₃NPs质量分数2.4%整理后的棉织物疏水拒油性能显著提升,其表面水接触角155°,达到超疏水性能,耐油污性能明显提高;负载Cs_0.33WO₃质量分数0.075%时棉织物UPF为153.3,远高于未处理的棉织物(UPF为15.03),棉织物负载Cs_0.33WO₃质量分数3.6%时使自制隔热装置温度降低4.1℃,整理过的棉织物紫外-可见光-近红外区域具有较强的光屏蔽性能。整理后的织物风格没有太大变化,透气性良好,具有良好的机械稳定性。

Abstract: To prepare multifunctional cotton fabrics with water and oil repellency, UV resistance and heat insulation, fluorosilane triethoxy-1H,1H,2H,2H-tridecafluoro-n-octylsilane (POTS) and cesium tungsten bronze nanoparticles (Cs_0.33WO₃ NPs) were co-blended in ethanol, and then the fabrics were dip-rolled and dried in a "one-step" process. The effect of the mass fraction of Cs_0.33WO₃ NPs on the UV resistance and thermal insulation of the cotton fabrics was investigated. The results showed that the water and oil repellency of the cotton fabrics after finishing with POTS mass fraction 2.3% and Cs_0.33WO₃ NPs mass fraction 2.4% was significantly improved, with a surface water contact angle of 155°. The oil resistance of the cotton fabrics with superhydrophobic properties was significantly improved. When the cotton fabric was loaded with Cs_0.33WO₃ mass fraction 0.075%, its UPF was 153.3, much higher than that of the untreated cotton fabric (UPF was 15.03), while the temperature of the self-made thermal insulation device was reduce by 4.1 ℃, and the finished cotton fabric with UV-Visible-near infrared region had strong light shielding performance.The finishing fabric, with no great change in style, exhibited good breathability and mechanical stability.
