Abstract

Dyeing can be a good entrepreneur work if it is done with the help of locally available dye source. Dye obtained from leaves of Datura stramonium applied on bleached eri silk yarns is a good source of dyeing. All the three mordanting methods can be used for dyeing pre, post and simultaneous mordanting with selected mordants namely alum, copper sulphate, ferrous sulphate and stannous chloride. Various optimized conditions were recorded such as wavelength (545 nm),75 min extraction time, alkali concentration of 2.5%/100 g of yarn, 45 min dyeing time, 5% dye material concentration, mordant concentration of 6% alum, 3% copper sulphate, 2% ferrous sulphate and 2% stannous chloride and 30 min mordanting time for all mordants. Colourfastness to washing, sunlight, perspiration, pressing was also studied on four different colour shades and found coppersulphate mordanting sample as the best method. The experiment was conducted during 2011-12 at AAU Jorhat and  survey was conducted in  village of  Kokrajhar district durimg 2014 after another trial in the same village  and 30 members were randomly selected. A questionnaire was prepared through which the background of the respondents such as caste, marital status and education qualification was studied. The preference of datura dye was also studied and found that 80% women prefered the dye and want to use it for future dyeing. Dried form of datura dye was stated to be better as fresh form may be unavailable in all seasons.
