摘要: Abstract In this study, we investigated that how the crystalline structure of cellulose in cotton linters changed during soda, sulfate and organosolve pulping processes by using X-ray diffraction FT-IR spectroscopy. It was defined more effected than soda pulping. found degree crystallinity crystallite size were higher While I α (triclinic) determined all pulp samples, unit cell only samples obtained at 130 °C among other samples. concluded not chemical agents, but also temperature pressure cooking digester had major effects on cooking.
