Shoddy
Shoddy originally denoted the waste from the manufacture of wool, and this was hardly utilised; but since then this waste, together with cuttings of flannel, wool, etc., is redevilled, spun, and woven into fresh cloth, being called new shoddy, to distingnish it from similar cloths manufactured from old clothes, this latter being called old shoddy. In the same way we have new mungo, formed from clippings of milled cloth, and old mungo, formed from old cloth. Shoddy is not so lasting as the original material, but is much cheaper.
