Federal Trade Commission Definition for Acrylic Fiber: A manufactured fiber in which the fiberforming substance is any long-chain synthetic polymer composed of at least 85% by weight of acrylonitrile units (-CH2-CH[CN]-)x. (Complete FTC Fiber Rules here.)

Basic Principles of Acrylic Fiber Production — Acrylic fibers are produced from acrylonitrile, a petrochemical. The acrylonitrile is usually combined with small amounts of other chemicals to improve the ability of the resulting fiber to absorb dyes. Some acrylic fibers are dry spun and others are wet spun. Acrylic fibers are used in staple or tow form. For a detailed production flowchart (wet and dry spun), go here.

Acrylic fibers are modified to give special properties best suited for particular end-uses. They are unique among synthetic fibers because they have an uneven surface, even when extruded from a round-hole spinneret.
