The Preparation and Properties of Regenerated Cellulose containing Vinyl Polymers IIndashStaining, Swelling, and Stiffness Characteristics

Staining and swelling tests have confirmed that vinyl polymers may be readily deposited inside viscose rayon filaments and that different degrees of penetration are obtained depending on the properties of the monomer employed. Vinyl polymers increase the stiffness of viscose rayon filaments, and as increasing amounts of polymers are deposited internally the filaments become increasingly distended. About 8% of polymer may, however, be introduced without causing any change in the diameter of the fibres.
