                The Reifenhäuser REICOFIL® spunbonding technology

                Primary process characteristics:
                 Modular structure of the spunbonding and melt blown components 
                 Common operating console for all spinning stations 
                 Common high-speed spinning belt for all spinning stations. 
                 High-speed winding system with downstream slitter/rewinder 

                Approx. 40% of all melt blown fabric is manufactured as pure melt blown fabric, the rest is used in composites with spunbonded fabric or in laminates with film.

                Process description:
                Out of the silo the polymer is vacuumfed to dosing station on top of the extruder. Inside the extruder it becomes melted and homogenised. Passing a filter system and a spin punp, the melt is distributed by a coathanger die, feeding the spinneret which forms a curtain of filaments. The filaments are cooled by means of a stream of air in a blowing area, drawn by aerodynamic forces and then transported to the downstream discharge channel. Here the filaments are swirled around and then deposited on the wire mesh belt as a random nonwoven material. This is transferred to the heat bonding calender which by heat and pressure sets the physical properties as tensiles and elongation of the final product. After calendering the material is cooled by a water-cooled pair of rolls and then wound up.

                The Reifenhäuser REICOFIL® spunbonding technology convinces by simple handling and low energy consumption (1 - 1.2 kWh/kg) for melting and conveying the raw materials.
