The meaning of the α-fraction, how hemicellulose wastes reagents, and the number to check on every TDS.
This primer is being prepared by our technical team. The full article will unpack the α/β/γ fraction separation, why hemicellulose consumes etherifying and esterifying reagents without contributing to target polymer properties, the typical α-cellulose levels in leading refined cotton grades, and how to read the figure on a TDS and verify it on a batch COA.
Full article coming soon. In the meantime, ask us for the current α-cellulose spec on any M / X / C series grade — we ship every batch with a matching COA.
TechnicalA buyer's guide to refined cotton viscosity grades: low, medium and high viscosity ranges, how viscosity relates to degree of polymerization, and what alpha-cellulose, ash and iron mean for downstream etherification and esterification.
