Acrylic fiber acquires an eminent position in the family of synthetic fibres. It replaces wool in the major applications, particularly in hand knitting and hosiery garments. The majority of knitting yarns which goes into the manufacture of pullovers, sweaters, socks, etc. Blankets and carpets are the other application where acrylic fibre competes with wool because of its high elasticity, colour brilliance, ease of washing, resistance to pilling and good light and colour fastness. Because of these properties and also due to the ease with which modification can be made during synthesis, spinning and finishing, acrylic fibres have experienced tremendous growth.


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.
