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红TR-16的棉织物进行处理,并通过光照比较他们的耐光效果。测定光稳定剂和分散红TR-16的紫外吸收光谱图,以及染色棉织物上光稳定剂在光照前后的紫外线透过率。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。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 fiber,well covering the dye molecules,strong intermolecular bonding with the dye molecules,improving the distribution stability of the UV absorber.
