Spunbond Nonwoven Compound (PLA/PBAT)

About This Product

Spunbond Nonwoven Compound is a PLA/PBAT blend supplied as a pellet compound for spunbond lines. The PLA component carries the tensile strength and thermal stability a filament needs to survive drawing, while the PBAT component softens the fabric and brings the bonding temperature down. Melt uniformity and filterability count for more in this grade than in most compounding. Spunbond fabric is extruded, drawn and bonded in one continuous process, so the resin must spin at fine filament diameters without breaks at commercial line speeds. Everything happens in series and in seconds: the melt leaves several hundred holes in a spinneret, is attenuated by an air stream to a fraction of the hole diameter, is laid at random on a moving belt and is bonded at heated calender points before it reaches the winder. A single gel breaks a filament, a broken filament wraps a roll, and the line stops. This compound is formulated for spunbond lines in a biodegradable system. Fabric weight, tensile strength and hand are set by the line and the basis weight rather than by the resin alone. Supplied as a raw material for processing on the buyer's own line. We do not produce finished articles. It is used in hygiene nonwovens, in medical fabrics and in agricultural covers. Bio Green Chem supplies Spunbond Nonwoven Compound to specification on melt flow, filterability, filament fineness and the basis weight your line runs.
