Abstract
Synthetic fibers form an important part of the textile industry. A disadvantage of synthetic fibers is their low hydrophilicity. PET fibers are particularly hydrophobic. This affects the processability and functionalization of the fibers. A relatively new and promising alternative is the use of enzymes in surface modification of synthetic fibers. Enzymes have been reported to increase hydrophilicity of polyesters by hydrolysis of ester bonds. This facilitates functionalization processes. The aim is to functionalize PET textile materials using modern biotechnology. The research will result in new, specific knowledge and technologies to create biotechnologcially modified textile materials thereby contributing to the transition towards a bio-based economy.
