摘要：

为提高棉织物的抗紫外线、疏水和柔软性等服用性能,以纳米ZnO、甲基丙烯酸十二氟庚酯、3-(异丁烯酰氧)丙基三甲氧基硅烷、甲基丙烯酸甲酯、丙烯酸丁酯为反应单体,采用半连续种子乳液聚合法制备得到核壳型纳米ZnO/氟硅改性聚丙烯酸酯乳液,然后用于棉织物整理。借助红外光谱仪、X光电子能谱仪和热重分析仪等对制备的乳液进行结构和性能分析,使用织物风格仪等测试了整理后棉织物的应用性能。结果表明:制备的复合乳液呈核壳结构,平均粒径为45.64 nm,Zeta电位平均值为-43.4 mV;整理后棉织物的紫外线透过率为2.13%,紫外线防护系数为50.18,具有良好的抗紫外线防护性能;整理棉织物的水接触角为136.14°,其弯曲刚度和动、静摩擦因数均明显下降,具有优异的柔软性及光滑的手感。

Abstract:

In order to improve the wearability of cotton fabrics, such as ultraviolet resistance, hydrophobicity and softness, the core-shell type nano-ZnO/fluorosilicone modified polyacrylate emulsion was prepared by semi-continuous seed emulsion copolymerization using nano-ZnO, dodecafluloroheptry methacrylate, 3-(trimethoxysilyl)propyl methacrylate, methyl methacrylate and butyl acrylate as reaction monomers, and it was applied to finishing cotton fabrics. Structure and properties of the prepared latex film were characterized and analyzed by infrared spectrometer, X-ray photoelectron spectrometer and thermogravimetric analyzer. Application performance of the finished cotton fabrics was tested by fabric stylistic instrument. The results show that the prepared composite emulsion has the core-shell structure. The average particle size is 45.64 nm and the average Zeta potential is -43.4 mV. The cotton fabrics treated with composite emulsion show good ultraviolet protection performance with the transmi-ttance (UVA) being 2.13%, and the ultraviolet protection factor 50.18. The contact angle of the fabric to water is 136.14°. The bending rigidity and friction coefficient (static and dynamic) is decreased obviously. The cotton fabric is endowed with excellent softness and smooth handle.

Key words: nano-ZnO, core-shell structure, fabric finishing agent, ultraviolet protection performance, hydrophobic performance
