Effect of Dehairing Process on Iranian Cashmere Fibre Properties

Abstract

\" To investigate the effects of dehairing process on the quality of cashmere fibres a series of tests was carried out. Iranian raw white cashmere was selected, scoured and dehaired mechanically by one and two dehairing passes, respectively. After dehairing the fibre properties such as length, diameter, coarse hair content, contaminations, fibre length and elongation were measured. Results showed that dehairing could result to shorter fibres and more fibre breakage. Fibre breakage increases by increasing the number of dehairing runs and it has a profound effect on decreasing the coarse hair content. Fibre strength and elongation at break in raw state is higher than the dehaired samples. \"
