Thermal bonded nonwovens are fabrics produced by using heat to melt thermoplastic powders or fibers (polyester, polypropylene, etc.). Since the bulk of thermal bonded nonwovens are produced using fibers, today we’ll spend some time discussing them. There are a number of ways to apply heat to the fibers. At the point where two or more fibers […]
Continuing our “How It’s Made Series,” today we’ll discuss how nonwoven needlepunch fabrics are made from webs of fibers (to see the web-making process, check out our carding/airlaid blog post).
