摘　　要：采用酸催化水解工艺,分别对钛酸四丁酯和十二氟庚基丙基三甲氧基硅烷进行水解,制备了具有硅羟基为端基的两种溶胶型整理剂,并采用激光粒度仪对所制备的溶胶进行了分析。然后对厚重双绉真丝织物进行了防紫外拒水整理,讨论了整理品的防紫外、拒水等性能及耐洗性。粒径分析表明,本方法制备了粒径分布均匀、粒径大小在100 nm之内的钛溶胶。经钛溶胶整理后的真丝织物的UPF值由原来的31.99提高到136.54,经过水洗后为95.61;表面与水的接触角为137.6°,经过20次水洗后为102.5°。与未处理的真丝比较,用不同整理剂处理后的真丝织物其断裂强力有所下降,纬向撕破强力和抗弯度有所提高,其它性能变化不大。Two kinds of sol-type finishing agents with the end group of silicon hydroxyl are prepared through applying acid catalysis hydrolysis process to hydrolyze tetrabutyl titanate and twelve fluorine heptyl propyl trimethoxy silane. Besides, laser particle analyzer is adopted to analyze the sol prepared. Anti-UV and water-repellent finishing is conducted for heavy weight Crepe-de-chine real silk fabrics. Anti-UV and water-repelleney performances and washability of the finished fabrics are discussed. The particle size analysis shows this method can be used to prepare titanium sol with even particle size distribution and the particle size in 100 nm. UPF value of real silk fabrics finished by titanium sol rises to 136.54 from 31.99 ; after washing, the value decreases to 95.61. The contact angle between the surface and water is 137. 6°; it changes to 102. 5° after washing for 20 times. Compared with real silk unfinished, the breaking strength of real silk fabrics treated by different finishing agents declines; broadwise tearing strength and anti-bending length increase. The changes of other performance change little.
