Abstract

Comparative study of Sapindus emarginatus vahl as natural soap and synthetic soap for scouring of cotton was carried out. Scoured samples were tested for physical properties expressed as cotton scoured with Sapindus emarginatus vahl. showed high tearing strength. Scoured cotton samples were mordanted with Terminalia chebula Linn, Punica granatum Linn as natural mordants and stannous chloride, potash alum as metal mordants. Physical and fastnesss properties of mordanted and dyed cotton samples were assessed. Significant improvement was noted in terms of Sapindus emarginatus Vahl. as natural soap compared to synthetic soap. Natural soap was also found suitable in improving sunlight and wash fastness compared to synthetic soap.
