ABSTRACT:
Process for the production of non-woven textile fabric from non-woven fabric waste material in which the waste is mechanically reduced to a particle size of less than three-fourth inch, preferably less than one-half inch and more preferably to a size of three-sixteenth to three-eighth inch, and reused, preferably as a blend with fibers (e.g., virgin or conventionally reclaimed) three-fourth inch or greater in length, to form the non-woven fabric. Addition of binding material other than that already contained in the waste is normally not necessary.
Process for recycling and reclaiming non-woven textile waste by mechanically reducing the size of such waste by mechanically reducing the particle size of the fabric waste to less than three-fourth inch, preferably by first cutting it with cutters and then hammer milling the cut waste in a hammer mill having a sized screen through which the hammered cut waste is forced.
A non-woven textile fabric containing at least 25% and as high as 98% by weight of mechanically reclaimed non-woven waste, the particle size of which has been mechanically reduced to less than three-fourth inch, preferably less than one-half inch, and fibers which are other than non-woven fabric waste and which have a fiber length of three-fourth inch or greater.
