内含双二氯均三嗪基团的真丝织物抗皱剂的合成

Synthesis of Silk Fabrics Anti-wrinkle Agent Containing Dual-dichloro-S-triazine Group

以三聚氯氰与间苯二胺单磺酸为原料,合成了分子中具有两个二氯均三嗪基团的整理剂(BTBSA),并通过浸渍整理工艺用于真丝织物的抗皱整理。考察了浸渍液pH值、温度及保温时间对真丝表面BTBSA吸附效率和固着效率的影响,并测定整理织物的性能。结果表明:pH值为10、温度为50℃、保温时间为60min时,吸附效率和固着效率达到最大值,分别为43.3%和41.1%;整理后真丝织物折皱回复性能大幅提高,急弹和缓弹折皱回复角分别由187°和228°提升到255°和304°,而整理后真丝织物的白度、断裂强力和硬挺度基本不变。

In this study, cyanuric chloride arid metaphenylene diamine mono-sulfoacid served as raw materials to synthesize the finishing agent containing two dichloro-s-triazine group （BTBSA） in its molecules. The finishing agent was applied for anti-wrinkle finishing of silk fabrics through dipping finishing process. The effects of the pH value of the dipping solution, its temperature and time on the adsorption and fixation efficiency of BTBSA on the surface of silk fabrics were studied, and the properties of fabrics were measured. The results show that： the adsorption and fixation efficiency of BTBSA reach the maximum values （43. 3% and 41.1%, respectively） under such conditions： pH value 10, temperature 50℃ and time 60min. After finishing, crease recovery performance of silk fabrics greatly improves. Especially, under the optimum finishing conditions, the cute and slow wrinkle recovery angles improve from 187° and 228° to 255° and 304°, respectively. The whiteness, breaking strength and stiffness of the finished silk fabrics basically remain unchanged.
