Abstract
Pulp with a high hemicellulose level is blended with a dissolving grade pulp and converted to viscose. Blending can be performed during steeping or after steeping. Spinning of the viscose containing the blend, into filaments yields fibers with strength properties that are at least equal to those of the dissolving pulp alone.
