Abstract:
The effects of time, temperature, concentration, and catalyst on the reaction between cotton fabric and bis(4-isocyanatocyclohexyl)methane in N,N-dimethylformamide have been studied. The reaction was carried out without pretreatment of the fabric or the reagents used. Diisocyanate-treated fabrics possess high wrinkle-recovery angles with moderate losses in tearing strength and abrasion resistance. The treatment produced fabrics that were resistant to acidic and basic hydrolysis, chlorine damage, rot, and degradation from repeated home laundering. The abrasion resistance and tearing strength of the treated fabrics were significantly improved when n-octadecylisocyanate was used as a co-reactant.
