woven cellulosic composites
|Abstract(s):||This work intended to study the production of composite using enzymatic modified woven cellulosic fabrics made up from fibres of cotton, linen and bamboo viscose. The adhesion of the fabric will be promoted using different mixture of cellulase enzymes. The properties of the woven fabrics and produced composites were characterized using several physical tests. The cotton & viscose composite appear to be the best combination exhibiting improved breaking force (0.5% of Xylanase PLUSTM) and percentage of elongation at maximum force (0.1% of Xylanase PLUSTM), as well as on the peel adhesion test (0.5% of AlternaFuel® MAXTM). The linen & cotton combination did not show any improvement for all the tested properties. Linen & viscose combination despite did not show peel strength improvement, exhibit remarkable elongation and breaking force (0.5% of Xylanase PLUSTM). Since there is no emission of volatile products it is expected a great public acceptance. However, higher enzymatic concentrations should be studied to clarify the contribution of this parameter on the surface modification and adhesion promotion.|
