HG NONWOVEN MACHINERY CO.,LTD.
Spunlaid nonwovens are made in one continuous process. Fibres are spun and then directly dispersed into a web by deflectors or can be directed with air streams (melt blown). This technique leads to faster belt speeds, and cheaper costs. PP spunbonds run faster and at lower temperatures than PET spunbonds, mostly due to the difference in melting points. Spunbond has been combined with meltblown nonwovens, conforming them into a layered product called SMS (spun-melt-spun). Meltblown nonwovens have extremely fine fibre diameters but are not strong fabrics. SMS fabrics, made completely from PP are water-repellent and fine enough to serve as disposable fabrics. Meltblown is often used as filter media, being able to capture very fine particles. Spunlaid is bonded by either resin or thermally. Melt Blown non wovens are produced by extruding melted polymer fibres through a spin net or die consisting of up to 40 holes per inch to form long thin fibres which are stretched and cooled by passing hot air over the fibres as they fall from the die. The resultant web is collected into rolls and subsequently converted to finished products. The extremely fine fibres typically polypropylene differ from other extrusions particularly spun bond in that they have low intrinsic strength but much smaller size offering key properties. Often melt blown is added to spun bond to form SM or SMS webs, which are strong and offer the intrinsic benefits of fine fibres such as fine filtration, low pressure drop as used in face masks or filters and physical benefits such as acoustic insulation as used in dishwashers. One of the largest users of SM and SMS materials is the disposable diaper and feminine care industry
