This article attempts to dye 100% cotton and polyester/cotton with disperse dyes through the use of cross-linking agents and catalysts. The study has indicated that it is possible to apply disperse dye on both the components of polyester-cotton blend. The experiments on 100% cotton alone has clearly demonstrated that the disperse dye which is normally used for polyester can also go on cotton, provided suitable cross linking agent for linking hydroxyl groups present in the cotton fiber is chosen and cross linking brought about in presence of an acid catalyst. While undergoing crosslinking, disperse dye which is normally used for polyester can also go on cotton, provided suitable cross linking agent for linking hydroxyl groups present in the cotton fiber is chosen and cross linking brought about in presence of a acid catalyst. While undergoing crosslinking, disperse dye molecules which have entered the amorphous regions get entrapped. The experiments carried out with Poly Glycols as cross linking agents indicated that Polyethylene Glycol-200 is having the correct dimensions for cross linking the hydroxyl groups present in the amorphous region of cotton which as envisaged has resulted in the considerable improvement in crease recovery angle. |
