摘要: 本文利用3,4-二羟基苯甲醛溶液和硝酸对羊毛织物进行处理,在一定条件下可在纤维上显示颜色。通过一系列实验,探讨了上述3,4-二羟基苯甲醛在硝酸条件下的显色特征,考察了浓度、温度、时间对显色的影响。实验结果表明,处理后的羊毛织物显黄棕色,且色泽鲜艳,匀染性好,其水洗、摩擦色牢度均达到4级以上;同时其纤维表面结构、断裂强力基本没有变化。最佳工艺条件:3,4-二羟基苯甲醛溶液的浓度为2.5%,浓硝酸的用量为1.5%,处理温度为80℃,处理时间为2min,浴比为1:25。

Abstract: In this article, According to the theory of the tryptophan reacted with the benzaldehyde derivative, 3,4- dihydroxy benzaldehyde was chemically reacted with the wool fabric under the acid condition, to achieve the coloration purpose. The results showed that the fastness of treated fabric was up to 4 grade or above. Meanwhile, the surface of fiber had not been changed, with the breaking strength not being affected, and the reacting time had been also reduced greatly. The optimal condition for wool coloration with non-dyestuff was: the concentration of 3,4- dihydroxy benzaldehyde solution and concentrated nitric acid 2.5% and 1.5% respectively, reacting temperature 70℃ and reacting time 2 min, bath ratio 1:25.
