Abstract

In this study, the properties of hand sheets from SALIX NIGRA wood kraft and soda pulp were investigated. Average dry and bulk density of this wood were determined as 0.35 and 150 kg/m3 and the average fiber dimension including fiber length, fiber diameter were measured as 1100 and 30 mm, respectively. The chemical compositions were determined as cellulose 42%, lignin 28% and extractive 4%. Wood was pulped using both Kraft (Sulfate) and SODA PROCESS. Pulps were refined to 360±60 ml CSF and then hand sheets were prepared using a combination of different percentages of hardwood pulps and the pulp produced in this investigation. Fiber dimensions, physical properties and chemical composition and the pulping yields were compared using mean and standard deviation as defined in randomized complete block design experiment. Duncan multiple range test was used for grouping the averages. The paper strengths of the pulps produced using two hour cooking showed better results than one hour cooking time, and the paper strengths of the pulps produced using 22% alkali show better result than 18%. Also the strength of the hand sheets with 100% produced pulps showed better result than hand sheets with 25% hardwood pulp (100% contained only kraft pulp of SALIX NIGRA). The results indicated that Kraft pulp from SALIX NIGRA wood will provide suitable pulp to be mixed with short fiber hardwood pulp.
