| dc.description.abstract | "The present investigation was carried out during the period 1998-99. The main objectives of the study were, to determine the effectiveness of acid and reactive dyes on UAS sheep breed wool fibre and yam, to assess the physical parameters of UAS sheep breed wool sample before and after dyeing and to find out the colour fastness properties of the dyed sample for different parameters like sunlight, washing, perspiration, crocking and hot pressing. The triple cross bred UAS sheep breed wool was selected from Poultry, Sheep and Goat Department, Main Research Station, University of Agricultural Sciences, Dharwad. Wool sample collected was of mixed lot from two different shearing seasons namely Spring clip (March) and Autumn clip (September). The wool sample was cleaned, carded and spun into a yam with the help of Medleri charaka. Later it was scoured and dyed with acid and reactive dyes. The effect of scouring and dyeing on wool was found out by assessing the physical parameters of wool fibre and yam before scouring, after scouring and after dyeing. Colour fastness tests to washing, crocking, perspiration, hot pressing and sunlight were carried out ^and was assessed with the help of gray scale. The results obtained were statistically analysed using completely randomized design and correlation test. Results revealed that scouring had more adverse effect on wool than dyemg. Higher absorption was exhibited by acid dyes. Acid dyes were safer on wool than reactive dyes. They had least effect on the physical parameters of UAS sheep breed wool fibre and yam after dyeing. The colour fastness of acid and reactive dyes to washing was very good, to crocking was good, to perspiration was fair, to hot pressing was excellent and colour fastness to sunlight was found to be good." | en_US |
