摘要:
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.
