Preparation of highly hydrophilic polyester fabric with ionic reagent

The polyester fabric was ionized with ionization reagent. The ionized polyester fabric had wonderful hydrophilic property,and its water contact angle decreased from 157. 25° to 0°; capillary rise height increased from 0. 35 cm to 14. 93 cm; and hydrophilicity did not affected by storage or washing cycles. SEM observation showed that there were more grooves on the surface of the treated fibers. There were sulfo groups on the fabric surface according to infrared spectroscopic analysis. Besides,X-ray showed the crystal texture changed little. And the strength,elasticity and rigidity of the ionized polyester were all kept well in the scope of possible applications.
