Industrial pollution prevention dyeing of wool and polyamide 6.6 fabrics with dried mixture barks of dalbergia sissoo

Abstract

A process for dyeing wool and polyamide 6.6 in tan and peach puff hues, respectively, by warming the fabric at 90C in an aqueous solution of a product obtained from the barks of Dalbergia sissoo, wherein fabric to dyeing solution ratio is 1:10 and weight of the powder for one gram fabric is 0.25g (25% shade on the weight of fabric). Dyed fabrics were evaluated to determine the fixation of powder on textile fabrics and various color parameters. Fastness properties such as fastness to wash, fastness to light, fastness to dry crocking and fastness to wet crocking were also determined using standard procedures.
