Utilization of Pruned Branches from Lawsonia inermis (Henna) in Soda and Soda Anthraquinone Pulping

Abstract Abstract: this study aimed to evaluate the suitability of pruned branches of Lawsonia inermis (Henna) for soda and soda anthraquinone pulping to add economic value for this small tree (shrub). The investigations were carried out to determine fiber dimensions, morphological indices, chemical constituents, cooking trials were done with and without anthraquinone according to Technical Association of Pulp and Paper Industry (TAPPI). The short fiber of Henna (0.628 mm) compensated with wide fiber and lumen (83 µm) and (71 µm) respectively. The high lignin 28.8% and good cellulose 47% resulted in total yield ranged between 36.9-40.6%.
