Low temperature dyeing of wool with reactive dyes

Wool fiber was dyeing with alpha bromo acrylamide type wool reactive lanasol dyes at low temperatures(85~95 ℃),changing the dosage of addivtives and acetic acid,temperature and other parameters,and then optimize the process.In this way,the wool dyeing rate and fixation rate were both increased to a certain externt.At the same time,because of the low temperature dyeing,wool dyeing fiber′s breaking strength was improved,and through the auxiliary optimization,the fastness of dyed fabric was also increased.
