This invention relates a new enzymatic process for the modification of the
surface of synthetic fibres using a cutinase enzyme (3.1.1.74). The enzymatic
action causes the hydrolysis of the polyacrylonitrile fibres containing vinyl
acetate as a comonomer and polyamide fibres, improving their hydrophilic
characteristics and dyeing properties.
L'invention concerne un nouveau procédé enzymatique de modification de la surface de fibres synthétiques au moyen d'une enzyme cutinase (3.1.1.74). L'action enzymatique provoque l'hydrolyse des fibres polyacrylonitriles contenant vinylacétate en tant que comonomère, et de fibres polyamides, de manière à améliorer leurs caractéristiques hydrophiles et leurs propriétés de coloration.
