Methods for making fasteners

摘要

There is provided a hook fastener comprising a base, where at least one surface has a multiplicity of engaging projections, which projections have a top surface and an attached end that are arranged in a region to form one or more shapes. There is also provided a method for forming the above fastener comprising dispersing onto a contact release surface polymer particles in at least one discrete area forming a predetermined shape and forming preform projections. The front surface of the base is fixed to the terminal ends of at least some of the preform projections and then removed from the contact release surface in the form of the predetermined shape. In an alternative method polymer particles are uniformly dispersed onto a contact release surface using electrostatic attraction and selectively transferred to the base in the predetermined shape by masks or selective adhesion or the like.
