dc.description.abstractPoly(aerylonitrile) and poly(methyl methacrylate) were grafted onto standard and chemically modified celluloses under various conditions using Ceric IV ion as a catalyst. The effect of grafting on the tensile strength, crease resistance and the dye affinity of the cellulose substrates were investigated. Chemically modified celluloses were obtained by oxidation and cross-linking with various agents using standard procedures. Dyeing properties of the standard and modified celluloses were obtained using purified Chlorazol Sky Blue FF. It has been observed that: a. Oxidation and cross-linking deoreased the tensile strength of the fabric, b. Metaperiodate oxidation improved fabric crease resistance whereas other forms of oxidation tended to decrease the same property,en_US
