【摘要】 本文对同质异晶分散染料的上染影响,进行了理论分析,并以常用三只国产分散染料的实测数据为例,说明分散染料上染率的高低,并不决定于染料的晶型,而晶型对上染率的影响可因染色方法和分散剂而异,制备和选用分散染料的晶型时,对上染率的影响不能作为唯一依据,而应首先考虑其耐热凝聚性能。更多还原

【Abstract】 Through analysing theoretically the relationship between the dyeing capacity and the same substance but different crystal type disperse dyes, and the data of three usually used domestic disperse dyes, the author explains that the dyeing capacity of disperse dyes doos not depend on its crystal type, while the effects of crystal type on dyeing capacity has a connection with the dyeing process and the type of dispersing agent. And therefore, the type of crystal is not the only item which must be taken into consideration during manufacturing and selection of the disperse dyes, but the heating coagulation property of disperse dyes is the main item to be considered.更多还原
