摘要:

为探索光稳定剂结构与棉上分散红TR-16耐光牢度之间的关系,选用4类共12支光稳定剂对上染分散TR-16的棉织物进行处理,并通过光照比较它们的耐光效果. 测定光稳定剂和分散红TR-16的紫外吸收谱图,以及染色棉织物上光稳定剂在光照前后的紫外透过率。结果表明有较好效果的光稳定剂具有以下特点:最大紫外吸收能囊括分散红TR-16的紫外吸收波段;能与纤维形成平行的平面,较好覆盖染料分子;与染料分子可形成较牢固的分子间力,可提高紫外吸收剂的分布稳定性。

Abstract:

In order to study the relationship between light stabilizer’s structure and the light fastness of Disperse Red TR-16 on cotton, 12 light stabilizers of four main categories were selected to treat the cotton fabric which had been dyed with Disperse Red TR-16. The light fastness of the samples was compared. The UV absorption spectra of the light stabilizers and Disperse Red TR-16 as well as the UV transmittance of the dyed cotton fabric before and after illumination were measured. The results showed that good light stabilizer has the following characteristics: maximum UV absorption covering the UV absorption band of Disperse Red TR-16, parallel surface formed with the fibre, well covering the dye molecules, strong intermolecular bonding with the dye molecules, improving the distribution stability of the UV absorber.
