Part II: Textile Properties of Fabric Modified by Reaction with Phenyl Isocyanate

Abstract

Cotton print cloth modified by reaction with phenyl isocyanate in either pyridine or N,N-dimethylformamide has slightly enhanced breaking strength and elongation. The treated fabrics show good rot resistance but poor resistance to degradation by outdoor weathering. The isocyanate treatment gives a fabric of lower moisture regain and good stability to home laundering. For a given reaction, solvent degradation of the treated fabrics by chlorine bleaching and scorching bears an inverse relation to the nitrogen content of the fabrics in the range studied.
