A crimped, high wet modulus viscose rayon fiber having a multilobular, skin core cross-section wherein the core is surrounded by a discontinuous broken skin that imparts to fabrics an improved cover and hand properties. The fibers are formed from a modifier-free viscose. The elimination of the modifier reduces manufacturing costs and eliminates an environmental pollution problem created in the discharge of spinning baths containing modifiers.

Method of making viscose rayon

Viscose rayon

High wet modulus viscose rayon fiber having a skin core structure and having a multi-lobular cross-section that imparts to fabrics an improved cover and hand properties similar to those of cotton. The fibers are formed from a modifier-free viscose. The elimination of the modifier reduces manufacturing costs and eliminates an environmental pollution problem created in the discharge of spinning baths containing modifiers.

Viscose rayon and method of making same

A crimped, high-strength regenerated cellulose yarn of filaments having a broken skin-core cross-sectional structure of which the skin comprises at least about 20 up to about 40% of the cross-sectional area, the peripheral skin surface is substantially smooth and the core section is 'blown-out;' and a method of preparing the yarn from a specified viscose and spinning bath wherein the formed yarn is highly stretched and then crimped in the relaxed state in a plasticizing medium.
