Polyester fabric is dyed with azo dyes made by coupling an appropriate diazotized aminobenzene into a coupler prepared by reacting 2-chloroacetylchloride or 3-chloropropionylchloride with 2 moles of N-alkyl, N-cyanoalkyl, or N-benzyl-substituted aminobenzene. This class of azo dyes, when appropriately dispersed, produces dyeings on aromatic polyester fabrics with excellent substantivity, outstanding sublimation fastness, and good fastness to light. The dyes are applied to polyesters, such as polyethylene terephthalate, by carrier dyeing, pressure dyeing, and thermofixation methods.
聚酯织物使用偶氮染料染色,该偶氮染料是通过将适当的重氮化氨基苯与2-氯乙酰氯或3-氯丙酰氯反应生成的偶合剂偶联而成。该类偶氮染料在适当分散的情况下,可以在芳香族聚酯织物上产生染色,具有优异的亲和性、出色的升华牢度和良好的耐光牢度。这些染料通过载体染色、压力染色和热固定方法应用于聚酯,如聚对苯二甲酸乙二醇酯。
