Process Development for Printing on Silk Fabric (Mulberry) with Dye Extracted from Wax Mellow (Malvaviscus arboreus) Flowers

摘要

Studies were conducted to extract natural dyes from biomass product namely wax mellow. The study was done on the process development for printing on mulberry silk fabrics with Wax mallow (Malvaviscus arboreus) flowers- Extracted natural dye was used for printing with different mordants (alum, copper sulphate, ferrous sulphate, stannous chloride, dried pomegranate rind and harda). In all 6 different shades were developed. The printing parameters viz; amount of dye material concentrate and concentration of mordants for printing on mulberry and tasar silk fabric were optimized. Fastness properties (light, washing, perspiration and crocking) were also studied on these samples. There is a need to carry out further research in this field and explore the possible way for its use in other natural fiber viz., cotton, wool and jute etc. Natural fabric printed with natural dyes in soft and subdued shades creates a fashion statement. Thus it can be exploited commercially to create opportunities for rural employment.
