The concept of nanoengineering of linen textile materials, realizing spatially localized effects of
protein catalysts on polymeric cellulose companions and securing selective splitting of impurity compounds
with preservation of technologically valuable nanoformations of binders in the fiber structure, is presented. The
regulated degree of conversion of polysaccharides with the use of degradation products as secondary reagents
for chemical transformations of lignin and polyphenolic compounds leads to the production of materials with
new or improved functional and consumer properties.
