This machine is suitable for the hot rolling production process below 400m/min in the production lines of spinning paste, spunlace, needle cutting, hot air, etc. It is suitable for hot rolling finishing of polypropylene, polyester, aramid and other non-woven materials. The non-woven fabric can change the thickness, air permeability, compactness, roughness and other properties of the raw material through the hot roller with high strength, toughness and heat resistance under the action of temperature and pressure, so that the surface of the non-woven fabric can be smooth, The effect of leveling and improving strength can meet the different requirements of customers for non-woven materials.
