Konvencionalni postopek barvanja z indigoidnimi redukcijskimi barvili vključuje kemično redukcijo barvil v leuko vodotopno obliko, ki poteka v visoko alkalnem mediju (pH 11-14) ob prisotnosti močnih reducentov (večinoma natrijev ditionit, Na2S2O4). Pri tem se tvorijo velike količine toksičnih kemika ...

Grafting, using oxidative enzymes shows a high potential for wool fibres funktionalisation. In this work we attempt to graft on wool fibres with phenolic antioxidants order to introduce and improve the properties of the fibre. The approach of tyrosinase to oxidize tyrosine residues in wool proteins ...

Oznake:
barvanje tekstilij;poliamidna vlakna;encimi;indigo barvilo;patenti;
This invention concerns an ecologically friendly process of indigo (C.I. Vat Blue 1 ) dyeing of cellulose and polyamide-containing textile material with possibility of reusing (three or more times) the enzyme reduction dyeing bath. Procedure of dyeing cellulose and polyamide textile materials with e ...

The potential of tyrosinases to activate tyrosine residues of wool protein fibres for cross-linking with different materials like collagen, elastin and gelatine was assessed. Natural fibres like wool offer an excellent environment for the growth of micro-organisms when the conditions like moisture, ...

A novel protease produced by Bacillus cereus grown on wool as carbon and nitrogen source was purified. B. cereus protease is a neutral metalloprotease with a molecular mass of 45.6 kDa. The optimum activity was at 45 °C and pH 7.0. The substrate specificity was assessed using oxidized insulin B-chai ...

Due to the rising global environment protection awareness, recycling strategies that comply with the circular economy principles are needed. Polyesters are among the most used materials in the textile industry; therefore, achieving a complete poly(ethylene terephthalate) (PET) hydrolysis in an envir ...
