Weyerhaeuser Introduces Kraft Pulp Fiber For Lyocell

Weyerhaeuser Co., Federal Way, Wash., has developed Peach, a modified kraft pulp fiber that can be used to generate lyocell fibers for textile and nonwovens applications. With its uniformly stable low intrinsic viscosity, Peach is excellent cellulose feedstock for lyocell fiber manufacturing, according to the company. "A modified kraft pulp has a higher yield, due to the higher level of hemicellulose," said Marian Herz, product line market director, Weyerhaeuser's pulp business. "The higher yield can lead to lower fiber supply costs for lyocell manufacturers, when compared to the cost of today's dissolving pulps that are used for lyocell manufacturing."
