The Spunbond process is a nonwoven manufacturing system involving direct conversion of a polymer into continious filaments, integrated with the conversion of the filaments into a random laid nonwoven fabric.
Meltblown process is in which usually a thermoplastic, fiber forming polymer is extruded through a linear die containing several hundred small orifices. Convergent streams of hot air (exiting from the top and bottom sides of the die nosepiece) rapidly attenuate the extruded polymer streams to form extremely fine diameter fibres (1....5 m M). The attenuated fibers subsequently get blown by high velocity air on to a collector screen - thus forming a fine filtered,self-bonded, nonwoven meltblown web.
SM - SMS - MMM AND OTHER COMPOSITE PRODUCTS
SM-SMS-MMM are composites that are made by combining Mogul's Spunbond and Meltblown fabrics by calandering or ultrasonic bonding.
Hydroentangling refers to a method of bonding webs of fibers. The hydroentangled bonding technology is a system in which water is emitted under high pressure and velocity from closely positioned nozzles onto a web of loose fibers. The intensity of the water stream and the pattern of the supporting drum or belt entangle, spin and curl the web's fibers about one another. The entangling of the fibers and the friction between the web's fibers yields a cohesive web. The process makes a nonwoven fabrics with physical properties of softness, high bulk, drapability, stretchiness, good strength and depending upon the fiber used. aesthetics that mimic traditional knitted or woven textiles.
