Improving the properties of the polyester fabrics by grafting with 3-chloro-2-hydroxypropyl acrylate

Abstract

3-chloro-2-hydroxypropyl acrylate obtained by the esterification of epichlorohydrin with acrylic acid in the presence of zirconium silicate as a catalyst was used for grafting of the polyester fabric in order to improve some of its properties. The grafting was performed in the presence of (NH 4) 2 S 2 O 8 as a polymerization initiator. The grafted samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy analyses. The effect of grafting on the comfort indices (hygroscopicity and vapor permeability) and the tinctorial properties (color intensity and dyeing fastness) were analyzed. Further addition of AgNO 3 in the final reaction mixture used for grafting of polyester fabric confers antibacterial effect to the treated samples. The properties of the polyester fabric were highly improved by grafting with 3-chloro-2-hydroxypropyl acrylate.

Investigation of temperature-responsive and thermo-physiological comfort of modified polyester fabric with Sericin/PNIPAAm/Ag NPs interpenetrating polymer network hydrogel

“…At present, the main treatment techniques for polyester fabric are copolymerization and covalent crosslinking. Muresan et al 7 grafted polyester fabric using 3-chloro-2-hydroxypropyl acrylate as catalyst to increase the hygroscopicity of polyester fabric. However, this grafting method cannot easily obtain uniform crosslinked polymers.…”
