Abstract
Bamboo is considered to be an important biopolymer source with useful applications in various fields, including the textile industry. In the present study, the bamboo rayon fabric has been grafted with acrylic acid using potassium persulfate (KPS) as an initiator. The graft copolymerization parameters were optimized in terms of temperature, time, initiator concentration and monomer concentration. The grafted product was characterized by FTIR, TGA and SEM analyses, and was further evaluated as to properties like moisture regain and yellowness index. The ungrafted and grafted fabrics were then dyed using cationic dyes. The colour strength increased with an increase in the carboxyl content of the grafted product. The dyed samples showed a distinct improvement in fastness properties.
