Optimization of dyeing conditions for Reactive Red 2 on mulberry silk waste/wool blended fabric

Silk and wool are protein fibers due to the presence of amines, carboxylic acid, amide, and other polar groups and therefore possess similar chemical properties. Silk and wool blends are dyed in piece form or as yarn on packages and hanks. Silk is chemically related to wool because the amino groups are integral components of both fiber, thus both can be dyed with the same dyes. The present study was undertaken to study the statistical optimization of Reactive Red 2 dye on mulberry silk waste and wool blended fabric. Optimization is done on the basis of Commission Internationals Del’ Eclairage (CIE) Lab colour space, K/S values (relative colour strength of dyed fabrics) and wash fastness grades
