Application of TEG Replacing Urea in Silk Printing with Reactive Dyes

Abstract:

In order to resolve the problem of water pollution owing to using a large number of urea in silk printing with reactive dyes, TEG (Triethylene glycol/3, 6-dioxaoctane-1/8-diol) was used to replace the urea. The effects of TEG on the performance of monochromic and combination printed fabrics were studied through testing K/S values (color depth) and Delta E (color differences) of printed fabrics. Meanwhile, the effect of TEG and urea on the solubility of reactive dye and the moisture absorbency of silk fabric were compared by testing the solubility of reactive dyes and the diameter of silk fiber respectively. The results indicated that the best replacement ratio of TEG to urea was 75%.
