Abstract
Poly(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,
