Method and device for functionalizing the surfaces of adhesive closure parts

摘要

The invention relates to a method for functionalizing the surfaces of adhesive closing parts which form, with correspondingly formed adhesive closing parts, an adhesive closure that can be repeatedly opened and closed. The surface energy of the adhesive closing part is modified by means of a proton and/or electron exchanging medium, especially in the form of donors or collectors, using high energy in such a way that the physicochemical properties of the material of the adhesive closing part can be adjusted without a coating and with ageing resistance, by the attachment of functional groups of the exchanging medium to the adhesive closing part material. The invention also relates to a device for carrying out one such method.

主权项

1. A method of functionalizing the surface of an adhesive closure member having a plurality of fastener elements adapted for mating with a corresponding adhesive closure member, said method comprising the step of:
subjecting the surface of the adhesive closure member including the plurality of fastener elements with a proton and/or electron exchange medium in the form of donors and collectors to modify a surface energy and to introduce a functional group to the surface of the adhesive closure member to resist aging of the adhesive closure member and where said fastener elements are free of coatings after introduction of the functional group.
