Spunbond / Thermobond
Kansan Materials provides hydroentanglement, dryer and winder units for spunbond and thermobond production
Spunlaid, also called spunbond, nonwovens are made in one continuous process. Fibers are spun and then directly dispersed into a web by deflectors or can be directed with air streams. 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 melt-blown nonwovens, conforming them into a layered product called SMS (spun-melt-spun). Melt-blown nonwovens have extremely fine fiber diameters but are not strong fabrics. SMS fabrics, made completely from PP are water-repellent and fine enough to serve as disposable fabrics. Melt-blown is often used as filter media, being able to capture very fine particles. Spunlaid is bonded by either resin or thermally. Regarding the bonding of Spunlaid. Some new generation of nonwoven is called Spunjet. Spunjet is the bonding of the Spunlaid filaments thanks to the hydroentanglement.
Kansan Materials provides hydroentanglement, dryer and winder units for spunbond and thermobond production processes. Kansan Materials offers flexible, reliable, cost-effective and ultimately customizable machinery systems at a high speed with optimized energy consumption.
