What materials can be bonded by ultrasonic welders for nonwovens/textiles? Can I bond dissimilar materials?
Materials may be 100% synthetic or blends with up to 40% natural fibers. Acrylics, acetates, polyester, nylon, polypropylene, spandex and PVC are all suitable for bonding or cutting. In general, the higher the synthetic content, the easier it is to cut and seal with ultrasonic energy. Nonwovens including felted filter media are especially suited for ultrasonic bonding. Yes, many dissimilar materials can be bonded together. Melt temperature difference for dissimilar materials can’t be greater than 50° F.
