Title: Research on Dyeing Process by Novel Low-Alkali Reactive Dye
Abstract: Novel low-alkali reactive dyes are used to dye cotton fabric because the amount of soda is excessive in conventional dyeing cotton fabric process with reactive dyes.This thesis discusses the factors affecting the K/S values,including salt,soda and dyeing temperature,etc.According to the results,the favorable conditions under which cotton fabric is dyed with low-alkali reactive dyes is shown as follows.When low-alkali reactive dye is 1 %(owf),the concentration of Na2CO3 is 1.5 g/L,the concentration of Sodium Sulfate is 70 g/L,fixation is carried out at 80 ℃ for 40 min and the liquor ratio is 1∶25;when low-alkali reactive dye is 5 %(owf),the concentration of Na2CO3 is 3 g/L,the concentration of Sodium Sulfate is 80 g/L,fixation is performed at 80 ℃ for 60 min,and the liquor ratio is 1∶25.The sodium carbonate needed by Low alkali dyeing fabric is only 10 % of that required when traditional reactive dyeing is used to dye fabric.Besides,it has high color yield and good fastness to rubbing and soaping.
