Abstract(s)The purpose of this work was to produce and characterize enzymatically treated fabric composites using different mixture of two commercial cellulase enzyme solutions in dosages of 0.1% and 0.5% in order to improve fabric’s adhesion. Three cellulosic taffeta plain weave fabrics of 100% flax, cotton and bamboo viscose were used in different combinations. The properties of the woven fabrics and produced composites were characterized using several mechanical tests. The cotton & viscose composite appears to be the best materials 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 better results on the peel adhesion test (0.5% of AlternaFuel® MAXTM). The flax & cotton combination did not show any improvement for all the tested properties. Flax & viscose combination despite did not show pell strength improvement, exhibit remarkable elongation and breaking force (0.5% of Xylanase PLUSTM). Since there is no posterior emission of volatile products one can expect 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.
