The present study focused in evaluation the characteristics of Sudanese Abelmoschus esculentus okra stalks in terms of fiber morphological properties, chemical composition, Soda-AQ pulping and papermaking characteristics and therefore indicate their suitability for paper pulp production. Franklin AM, Suzuki, A and Hongu, N. (2015). The combination of low yield but good papermaking properties suggested that okra pulps could be used in blends with the short-fibered hardwood pulps. Ullah S, Pakkanen H, Lehto J. Evaluation of general characteristics of okra stalks in terms of fiber dimensions morphological indices, chemical components, Soda-AQ cooking and to study their suitability for paper production. Conference on Pulp and Paper Development in Africa and Near East, vol. On the other hand they are an indication of easy access and degradation of the cell wall materials by weak alkali. Shahid MR, Amjad M, Ziaf K, Jahangir MM, Ahmad S, Iqbal Q, Nawaz A. Otherwise, over-proportional degradation and dissolution of hemicelluloses and cellulose might take place, resulting in reduced yield and viscosity. The silica content was comparatively high as usual for such non-woody raw material. A high hot water soluble content also indicated a higher accessibility of the cell wall components to pulping liquor. The high hemicellulose content also improved the beating [25, 29]. 2015;6:458. https://doi.org/10.4172/2157-7110.1000458. The high silica content causes difficulties in the regeneration of chemical pulping, but might be beneficial in total chlorine free (TCF) bleaching where sometimes silicates are added for stabilization of cellulose.

Tarig Osman Khider. We use MailChimp as our marketing platform. The highest viscosity was for 21% soda-AQ which reflected positively for all strength properties especially at high degree of freeness except for tear resistance. Production of paper pulps in good paper properties with low lignin content (kappa number) and improved viscosity could be expected. Authors grateful for the Cellulose Chemistry and Technology Research Unit- National Centre for Research (NCR) Khartoum, Sudan for using of research facilities. Abelmoschus esculentus okra stalks, fiber structure under microscope. The results of soda-AQ cooking of okra with 15-21% NaOH showed in Table4. Burst and tear strengths are highly correlated to a high proportion of hemicelluloses [30, 31]. The pulping is done at a recently commissioned wheat straw pulping plant that generates zero effluent and zero solid waste. Non woody plants and agricultural residues as flax, cotton, bamboo and cereal straw were used extensively in pulp and paper production. The cellulose (Kurschner-Hoffer) was (48.5%) which meant good pulp yields at suitable alkali utilization. California Privacy Statement, 2002;36(34):3536.
