Non-conventional scouring of cotton fibres of different species

Abstract

81-87The effect of non-conventional scouring treatment (NST), using exclusively non-ionic surfactant, on the properties of cotton fibres of different species has been studied. It is observed that for the treated G. arboreum, G. barbadense, G. herbeceum and G. hirsutum the sinking time remains within the standard limits. No significant effect on uniformity ratio is observed for all the samples except for G. herbeceum. A decrease in 2.5% span length is recorded with all species, except with G. herbeceum. The species G. arboreum and G. hirsutum show an increase in micronaire values while G. herbaceum shows a decrease in the value. The % elongation decreases for G. arboreum and G herbeceum. SEM micrographs also suggest that the NST method can be conveniently used for different species of cotton
