Forming Hook Fasteners Using Ultrasonics

The use of hook and loop fasteners (or "touch fasteners") as side tab closures has become a key feature on virtually all disposable diaper products currently on the market. Although a number of new fastening tape suppliers have entered the field, few significant technical improvements have been implemented to these closures since the introduction of touch fasteners. Traditionally, the hook side of the touch fastener is supplied in roll form and bonded to diaper side tabs or other substrates using ultrasonic welding technology. In this presentation a new technology is introduced that uses ultrasonics to form the fastening hooks directly onto or as part of the substrate itself. Aesthetically appealing, high performance fasteners are economically produced in situ, eliminating the need to purchase, ship, inventory and apply molded hook fasteners. This revolutionary technology will permit the creation of hooks or other fastening elements from films, fabrics, nonwovens and various laminates. The technology allows engineered fastening elements to be formed in a broad variety of patterns and locations on a substrate providing better draping, softer edges and enhanced conformability.
