Airlay S line
The Airlay-S line is Ramina’s innovative system that allows the aerodynamic web formation starting from natural, synthetic, shoddy or mineral fibers. The Airlay-S patented technology replaces the traditional carding and cross-lapping systems and allows the fibers to be placed in an S shape along the web thickness, increasing the longitudinal strength of the material. The Airlay-S line ensures a perfect fiber opening and dosing in order to provide high blending accuracy. The basic weight obtained using the Airlay-S patented technology ranges from 500 gsm up to 6.000 gsm. However, thanks to the combination with an air-card it is possible to create lighter products, from 160 gsm.
