This group covers:
Non-woven fabrics which are composed of the fibres obtained and reused by cutting or fibreizing wastes or garnets, and which are also included in the scope of the upper group, namely, formed wholly or mainly of staple fibres or like relatively short fibres and formed from fleeces or layers composed of fibres without existing or potential cohesive properties insofar as this use has no preponderant influence on the consolidation of the fleece.
