Abstract

See full text

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.
