Moisture crosslinking process of etherified 2D resin

A moisture crossinkling treatment was studied on cotton fabric with etherified 2D resin and MgCl_2·6H_2O as a catalyst at room temperature.The effects of resin dosage,catalyst dosage,pH value and curing time on the wrinkle recovery angle,tensile strength retention,whiteness,formaldehyde release were discussed.The optimized conditions were found as resin 200g/L,catalyst 24%,pH value 2,curing time 24 hours.The cotton fabric features improved recovery angle,strength retention above 60% and released formaldehyde content lower than 75mg/kg.
