Evaluation of Screen Printing using Cochineal Natural Dye- Crimson Publishers
Evaluation of Screen Printing using Cochineal Natural Dye by Subhas Ghosh in Trends in Textile Engineering & Fashion Technology
Recently a great interest has been developed
in the use of natural dyes for fashion apparel textiles which arises from the
restrictions on the effluent to be released from the dye houses to reduce
pollution. Wash colorfastness has been a continuing problem in the use of
natural dyes. This study addresses this issue by investigating screen printing
on cotton fabric using Cochineal natural dye in the presence of stannous chloride
as the mordant. It was found that, the dye recipe using 6% Cochineal pigment in
water-based solvent, where the fabric was soaked in the heated stannous
chloride mordant for an hour and cured at 160 °C for 3minutes, produced the
best screen print on 100% cotton fabric in terms of appearance and color wash
fastness.
