Viscose product
View Patent ↗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.
1. A viscose product, comprising:
at least 3.8 percent by weight hemicellulose; and
cellulose, wherein the non dissolving grade pulp used to make the product has a D.P. of at least 700, a hemicellulose level of at least 10% by weight, an S 18 of at least 13% by weight and an S 10 of at least 15% by weight.
2. The viscose product of claim 1 wherein the tensile strength is at least 20 cN/tex.
3. The viscose product of claim 1 wherein the elongation is at least 12%.
4. The viscose product of claim 1 wherein the modulus is at least 1000.
5. The viscose product of claim 1 wherein the product is one of a film or a fiber.
