Poor preparation of the goods is usually the major cause of poor quality dyeing and preparation should be of the highest quality consistent with the final price of the material. The preparation of acrylic fiber materials involves scouring and bleaching.
Today acrylic textiles can be dyed in any fashion shades with good fastness properties commensurate with their excellent end use properties. The development of special cationic dyes solved the initial difficulty of the dyeability of these fibres. Auxiliaries such as levelling agents and special washing off agents play an important role in colouration.
Cationic softener is the most commonly used softener, which is also a common auxiliaries for acrylic. Cationic softener can easily adsorb on the surface of the fiber with strong combining capacity and strong high temperature, washing resistance. Scroopy finish provides a unique finish giving acrylic material a crispy feel.
