Hills Develops Nanofiber Meltblown Fabric Technology
Hills said its development of meltblown nanofibers grew out of the company’s development of true bicomponent meltblown extrusion equipment. The company has used its patented printed-circuit-style extrusion dies to produce the fibers from high-melt-flow-index polypropylene. According to Hills, a hole count of 100 holes per inch and up and extremely high length-to-diameter ratios enable production of these nanofibers at reasonable rates, and puts meltblown production in the same size range that was previously the exclusive domain of multicomponent spinning or electrospinning technology.
