Graft copolymerization of acrylamide (AM) onto polyvinyl alcohol (PVA) fibers was carried out by the ceric ion method, and the properties of these fibers and the papers made from grafted PVA fibers were examined.
The following results were obtained.
The water retention value of grafted PVA fibers increased with the increase of grafting degree, while the tensile strength and the freeness decreased. The sheet strength was affected by the degree of grafting and the content of PVA fibers. When basis weight kept constant, the breaking length, the burst factor and the tear factor of heat-treated showed maximum value at the degree of grafting 5060 %. When the numbers of PVA fibers were constant, the breaking length and elongation showed constant value above 70 % of degree of grafting.
