Abstract
Methods of forming mold cavities suitable for hook and loop fastening are disclosed, along with effective hook construction and hook and loop fastener products that have an ultrathin cross-section. Photochemical techniques are employed to form plates that define hook-form mold cavities, and, alternatively, chemical etching is employed following preforming of the cavities and machining. Hooks having three-dimensional tapers with enhanced loop engaging characteristics are disclosed. By utilization of special surface finishes and tolerances, hook fasteners, having ultrathin cross-sections are realized, that pave the way for practical use of touch fasteners in a wide range of new areas.
