Acrylic Yarn

Acrylic fibres are synthetic fibres made from a polymer Polyacrylonitrile. The polymer is formed by free-radical polymerization in aqueous suspension.

The fibre is produced by dissolving the polymer in a solvent such as N
N-dimethylformamide or aqueous sodium thiocyanate, metering it through a multi-hole spinnerets and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a
stream of heated inert gas (dry spinning). Washing, stretching, drying and crimping complete the processing.

Practically all acrylic fibres are produced in staple fibre from with lengths varying from 38 to 64 mm for the cotton system and 75– to 125 for worsted system. The deniers range from 1.2 to 3.0 for normal application and 5, 7 & 15 for special applications.

Acrylic is lightweight, soft, and warm, with a wool-like feel. It has excellent colourfastness. It is resilient, retains its shape, and resists shrinkage and wrinkles. Acrylic is used in clothing as an alternative to wool.
