Enzymatic surface hydrolysis of PET enhances bonding in PVC coating
Almansa, E.; Heumann, S.; Eberl, A.; Fischer-Colbrie, Gudrun; Martinkova, L.; Marek, J.; Paulo, Artur Cavaco; Guebitz, G. M.The effect of polyesterase preparations from Thermomyces lanuginosus and Beauveria brongniartii on the hydrophilicity of PET materials was assessed. As a result of polyesterase treatment the hydrophilicity of PET fabrics was increased by up to 8 cm in terms of rising height with increases in surface tension from 6.2 mNm (heat-inactivated control samples) to above 8 mNm. Both enzymes were able to increase the am...
