Not exactly a textile fiber, but something used in the textile industry.

Acrylic elastomer is a general term for a type of synthetic rubber.

Acrylates are the salts, esters, and conjugate bases of acrylic acid and its derivatives. They are also known as propenoates (since acrylic acid is also known as 2-propenoic acid).  Acrylates and methacrylates (the salts and esters of methacrylic acid) are common monomers in polymer plastics.  Acrylate polymers belong to a group of polymers which could be referred to generally as plastics. They are noted for their transparency, resistance to breakage, and elasticity. They are also commonly known as acrylics or polyacrylates. Acrylate polymer is commonly used in cosmetics such as nail polish as an adhesive.
