Résumé
The present study entitled assessment of physical properties of camel and goat hair was carried out during 2004-06 to assess the physical properties of camel and goat hair, to compare the quality parameter of camel, goat and blended yams and determine the effect of acid and reactive dyeings on the colour fastness of camel yarn. The camel hair was procured from National Research Centre on Camels, Bikaner (Raj) and goat hair from Rajasthan Agricultural University Bikaner (Raj). The fibre samples were assessed for morphological, chemical and physical characteristics. The hair were distinctively handspun into camel, goat and blended yarns (Camel : goat 50:50) and were assessed for yarn count, yarn twist and single yarn strength. But camel yarn was alone dyed in acid and reactive dyes and assessed for colour fastness. From the results of pilot study yellow, green and blue colour and 2 per cent dye concentration was selected on the basis of dye absorption and visual appearance. Camel hair was relatively finer with lower medullation percentage compared to goat hair. Camel yarn was finer with greater number of tpi whose single yarn strength and elongation percentage was lower than to goat and blended yarn. Acid and reactive dyes showed significant adverse effect on yarn properties, that inturn resulted into yarn coarseness, lower tpi and decreased in single yarn strength regardless of hues and dyeing methods. Dyed samples showed good colourfastness to crocking and sunlight. Hence to enhance the appearance of camel hair, colour can be added as value addition that aids the young entrepreneurs to take up this venture and rejuvenate the applicability of speciality hair fibres.
