Evaluation for Paper Ability to Pseudo Stem of Banana Tree

In Paraguay, the pseudo stem of the banana tree is cut and broken after fruit annually, deposited in growing area for weathering. The wide availability of these pseudo stem transforms them into a potential source of raw material for processing into pulp for paper, justifying a preliminary screen of your paper ability.The fresh pseudo stems were subjected to a process for separating the fibrous material, dried in the atmosphere and the material obtained was stored until use. First tests were made in laboratory some alkaline Cooking of the material to evaluate the ranges of the operating variables: active alkali concentration, temperature and Cooking time and the appearance of the material obtained, and then tracking Cookings were conducted at pilot plant horizontal rotary digester, with 10, 5%AA 145° C for 45 minutes. The yield was determined and the drainability of the pulp obtained and prepared in the laboratory leaves was measured tensile resitence, RCT (Ring Crush Test) and CMT (Concora Meduim Test). He pulp yield is 54% of a typical chemical pulp and drainability of 215 mL CSF stands at the lower threshold of cellulose pulp. The tensile index with a value of 95 Nm/g corresponds to papers with high tensile resistance and RCT values of 215 N and 209 N CMT are satisfactory, and indicate that these pastes can be used in fillings for papers to corrugate. These results are promising and justify performing an experimental design to optimize the process.
