The melt blown process, used to produce nonwovens, is a complex technology which can produce unique, high value products.
It is, like spunbond, a single stage process, which moves directly from the polymer to the web: a pump forces the melt polymer through a spinneret having numerous, small holes. The filaments are drawn by very hot air flow becoming micro-fibers, which are then laid-down on a conveyor belt to form the web. Thermal bonding is the most commonly used process to stabilize the nonwoven, dimensionally and mechanically.
For some applications, like hygienics, melt blown and spunbond processes are used in combination to form multilayer fabrics. The melt blown process requires a tailored raw material, which has low viscosity and high consistency.
Customers select our Moplen and Metocene polypropylene resins for their melt blown applications, as they can provide very fine filaments, light-weight fabrics and excellent uniformity
