Durable Press Finishing of Cotton Fabrics Dyed with Henna (Lawsonia inermis Linn.) Leaves Extract

摘要

Cotton fabrics were treated with 1, 2, 3, 4-butanetetracarboxylic acid (BTCA) and then dyed with a natural dye extracted from henna (Lawsonia inermis Linn.) leaves. The effect of BTCA concentration on the dyeing properties of cotton fabrics was studied by measuring the K/S values of the treated dyed cotton fabrics. The wrinkle recovery angles of the treated dyed cotton fabrics were assessed. The results proved that the BTCA treated cotton fabrics showed increase dye uptake of cotton fabrics. Concentration of BTCA enhances the durable press and tensile strength of the dyed cotton fabrics. Fastness properties of these to wash, rub and light have also been discussed.
