Synthesis of the Hyperbranched Polymers-RSD Compound and its Application in Dyeability Modification of Cotton
A species of derivatives of HBP-NH2 was synthesized from methyl acrylate, diethylene triamine and dodecylamine by two different modes (HSDA-1 and HSDA-2). Its molecular weight and possible structure were characterized by gel permeation chromatography, fourier transform infrared spectrophotometry and nuclear magnetic resonance spectroscopy. Dyed with reactive dyes, the cotton fabric which treated with the aqueous solution of HSDA displayed dramatically enhanced color strength, even when dyeing without electrolyte. It is concluded that the HSDA polymer can be used as a high direct staining salt-free auxiliary in reactive dyeing on cotton.
