羊毛的变性及变性羊毛阳离子染料染色

羊毛经阴离子型活性变性剂处理后，纤维侧基上被引入阴离子型基因，具有和腈纶纤维类似的结构。因而，变性羊毛能够用阳离子染料染色。增大变性剂的分子量、共轭双键数及相对疏水性，变性羊毛用阳离子染料染色时上染速率和上染率均可显著地增大，染色牢度也大为改善，但对酸性染料产生防染作用。从变性羊毛的红外吸收光谱图上可看到，在波数为１１５０～１２６０ｃｍ－１、１０１０～１０８０ｃｍ－１和６００—７００ｃｍ－１处均出现磺酸基的特征吸收峰。变性剂和羊毛间形成共价结合成为纤维侧基的一部分。变性羊毛表面的电性能有较大变化，但其物理机械性能如减溶解度、弹性、断裂强度等基本不受影响。     

Determination of Absorbable Organic Halogen (AOX) Concentration in Wool Dyeing Effluent of Lanasol Dyes

In this paper, the absorbable organic halogen (AOX) amounts in the effluents from Lanasol reactive wool dyeing were determined using DIN 38409 H14 methods and compared with the remaining chromophore concentratlons which were determined spectrophotometrically. It was found that the dyes remaining in the dyeing effluents did result in AOX concentratiom. By measuring the adsorption rates of Lanasol dyes on activated charcoal at different temperatures and pH values, the maximum adsorption on activated charcoal and optimum adsorption conditions of the Lanasol reactive dyes were determined. The experiments showed that the AOX values of the dyes measured by these two methods were not in agreement.he reasons for this observation are discussed.
