| abstract |
A new process for enhancing the hydrophilicity of the surface of a polyolefin or polyolefin copolymer article is characterized in that the surface is treated with an enzyme selected from oxidoreductases, especially of the cytochrome P450 family or enzymes classified as EC 1.13 or EC 1.14. The process is especially useful for the treatment of polypropylene films, fibres, or fabrics, inter alia for use in sanitary articles, threads, yarns, fabrics, textiles, garments, technical or household articles, printed or dyed cover films or packaging films. |
