ClearRevealing pore size distribution in cellulose and lignin-cellulose man-made fibers – effect of draw ratio and lignin content
Researchers investigated pore size distribution in cellulose and lignin-cellulose man-made fibers using thermoporosimetry in the wet state and nitrogen sorption after critical-point drying, addressing the challenge that conventional pore analysis methods require dry samples but cellulose pores collapse irreversibly upon drying. Results characterized how lignin content and draw ratio during spinning influence pore structure, with implications for fiber performance and microplastic fiber shedding during use.
