Dyeing, moisture regain and mechanical properties of wool fabric grafted with PMMA by chemical and radiation-initiated methods

PMMA polymer has been grafted onto wool fabric by two methods of grafting preirradiation method and chemical initiation using KMnO 4/H 2SO 4 system. The grafted wool showed an enhancement in dyeability towards some basic dyes differing in size and chemical structure. Preirradiated grafted wool exhib...

Description
Summary:PMMA polymer has been grafted onto wool fabric by two methods of grafting preirradiation method and chemical initiation using KMnO 4/H 2SO 4 system. The grafted wool showed an enhancement in dyeability towards some basic dyes differing in size and chemical structure. Preirradiated grafted wool exhibited a relatively higher dyeing affinity than that prepared by the chemical method. Graft yield of up to 26% of PPMA did not have a noticeable effect on the moisture regain of wool fabric. Further increase in graft yield was found to cause a slight reduction in moisture regain. The tensile strength was reduced by the graft process, but elongation at break was not affected.
