摘要

In this study, a series of hydroxy ethyl cellulose (HEC)-based polyurethane dispersions (PUDs) were prepared by varying mole ratio of polyol and chain extender, using step growth polymerization. Prepared HEC-PUDs were analyzed by FTIR, 1H-NMR and XRD. Dynamic light scattering was utilized to monitor particle size. HEC-PUDs were applied on dyed, printed textiles to assess their textile performance. Surface morphology of finished and unfinished textiles was analyzed by scanning electron microscopy (SEM). Colorfastness properties of HEC-PUDs-treated fabric showed improvement in rating, such as fastness to washing (from 3 to 4 for dyed and 2/3–4 for printed fabrics), fastness to light (from 3 to 4/5 for dyed and 3/4–4/5 for printed), colorfastness to rubbing (from ¾ to 4/5 for dyed (dry), 2–3/4 for dyed (wet) and 3/4–4/5 for printed (dry), 2/3–3/4 printed (wet)). Pilling, tear and tensile strength were also improved. By increasing the amount of HEC, there is a gradual increase in antimicrobial activity against Staphylococcus aureus and Escherichia coli. This study presents an economical and greener method for the modification of textile surfaces.
