ABSTRACT:
The present invention provides a method for reducing a nonwoven fabric to flakes which can be recycled into the spinning system of a meltblowing, spunbonding or carding process. The process according to this invention is a noncontact one, involving the use of a hot air knife. The hot air knife emits a jet, or stream, of heated air under pressure at a high flow rate. A nonwoven fabric is contacted with the jet of air and as a consequence, the nonwoven web is physically broken into small pieces, or flakes. The resultant flakes are brushed off the conveyor and collected in a reclaim hopper; they are readily reprocessable due to their small size.
