MELTBLOWN & SMS NONWOVEN
Meltblown technology is a younger brother of the spunbond technology. The process allows the production of ultrafine filament nonwovens under very economical conditions. Thanks to its characteristic properties, meltblowns often are used as high-degree filter media for air, liquid and particles.
In the meltblown process, a thermoplastic fiber-forming polymer is extruded through a linear die containing several hundred small orifices. Streams of hot air — exiting from the left and right sides of the die nosepiece — rapidly attenuate the extruded polymer streams to form extremely fine filaments. The filaments then are blown by high-velocity air onto a collector screen, thus forming a fine-filtered, self-bonded nonwoven web. After that, they are bonded and wound to form roll goods for further processing.

CHARACTERISTICS

Difference between melt-blown nonwoven fabrics and other nonwoven fabrics, such as degree of softness, cover or opacity, and porosity can generally be traced to differences in filament size.
APPLICATIONS

Meltblowns are used mainly for absorbent cloths and wipes; oil absorption; and filtration for liquids, gas and air. Very important end-uses of meltblowns include sanitary applications such as hygiene and incontinence products for babies, adults and feminine hygiene. 
SPUN-MELT-SPUN (SMS) NONWOVEN

In the case of melt-blown web, additional process modifications can provide excellent flexibility in terms of designing new and novel products. Composite formation has been used extensively to supplement the limited physical strength of normal melt-blown webs and also to provide enhancement of other properties. This feature has been very effectively exploited in SMS structures based on a three-ply system consisting of Spunbond/Melt-blown/Spunbond plies to give an enhanced composite structure, supplementing the fiber and web properties of the melt blown with the strength and toughness of the spunbond surface fabrics. Lamination with a variety of other sheets and webs has also extended the range of properties achievable with melt-blown systems.
CHARACTERISTICS

Meltblowns are combined with spunbonds or laminated to form other materials. Combinations with spunbonded fabrics are primarily used to make nonwoven materials with barrier properties. Another variation is the combination of meltblown with cellulose or an absorbent powder to produce a soft, strong, but still absorbent material that can retain absorbed liquid while still keeping its strength. The outcome is a combination of spunbonds (S) and meltblowns (M), resulting in SMS, or other combinations, depending on the final product.
APPLICATIONS
Spunlaids also may be coated; having functional inserts for controlled absorption and, as mentioned, applied as composite material for many applications. From SMS everything can be manufactured and implemented. This setup increases the range of applications considerably — including, just to name a few:  
•    hygiene;  
•    baby and adult diapers;  
•    medical products;  
•    protective masks for medical use;  
•    general use as a barrier layer;  
•    combination with other nonwovens/area-measured material;  
•    paper composites;  
•    work safety;  
•    protective clothing; and  
•    breathing masks.
