Last updated: April 2026 dataDissolving pulp is a highly purified form of chemical wood pulp with alpha-cellulose content well above standard paper-grade pulp, making it the essential raw material for viscose/rayon fiber, lyocell, acetate, and cellulose ethers used in textiles, pharmaceuticals, and specialty films. Its purity specification — particularly low hemicellulose and lignin residuals — is what separates it from commodity kraft or sulfite pulp and commands a significant price premium. Trade in dissolving pulp is closely watched by the textile and specialty-chemical industries because supply tightness directly affects viscose staple fiber production costs.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Dissolving pulp typically requires alpha-cellulose content above 90–96%, with tightly controlled hemicellulose and lignin levels. Standard bleached kraft pulp for paper has lower alpha-cellulose requirements and higher residual hemicellulose, which would interfere with downstream chemical derivatization processes like xanthation for viscose production.
Viscose/rayon staple fiber producers are the largest consumers and most directly exposed, since dissolving pulp is their primary input with limited short-term substitutes. Acetate tow manufacturers (used in cigarette filters) and producers of cellulose ethers for pharmaceuticals and food additives are also significantly affected by supply or price volatility.
