Abstract

The effect of enzymatic preparations by protease and xylanase action on the physical and mechanical properties of fibrous materials is shown. The use of biomodification of plant biopolymer - gluten, allows reducing energy consumption for production and producing biodegradable fibrous materials. Replacement of formaldehyde resins used for the production of nonwovens, paper, paperboard, fiberboard, biomodified vegetable polymers treated with enzyme preparations, increases the strength and deformation properties of fibrous materials: stress at break up to 20 % (dry sample) and 31,2 % (wet sample),elongation at break up to 20 % (dry sample) and 31,6 % (wet sample) in comparison with control samples. The obtained results show the potential application of biocatalytic treatment of gluten to improve the mechanical properties of paperboard.
