Abstract

Anatomical, chemical and PULPING characteristics of COTTON STALK as a nonwood material.Fiber length, fiber diameter, lemun and cell wall thickness were measured at 24.47, 16.43 and 4.02 mn respectively. Paper making coefficients were also calculated coefficient, flexibility coefficient and ranckl coefficient were calculated at 34.28, 67.14 and 48.93 respectively.Chemical composition of COTTON STALK was determined at 47.83%cellulose, 21.66% lignin, 2.13% alcohol-acetone extractives and 2.83% ash.Soda PULPING at following variables was investigated. Three levels, of cooking temperature (140, 160 and 180 degree Celsius), three cooking time (30, 40 and 50 minutes) and raw material condition (normal and debarked stalks). Active alkali of 20% (based on NaOH) and liquor to wood ratio of 5: 1 were kept constant for all SODA cooks. The optimum combination of variables160 degree Celsius I temperature, 40 minutes time and debarked raw material. The YIELD and kappa no. of pulp obtained at this cooking condition was 50.4% and 89.15 respectively.
