ABSTRACT:
Reproducing, recoloring and/or recycling of used carpet tiles is provided. In accordance with one embodiment, used carpet tiles, which are recovered, are subjected to a choosing step according to the degree of stains, etc. The chosen carpet tiles are washed with a high-pressure fluid, and entangling of piles is removed and piles raised. The resultant carpet tiles are subjected to a choosing step once again according to the degree of stains, etc. The chosen carpet tiles are treated with such a design and color for recycling as to make less visible the stains or non-uniformity in color remaining after the washing, using a design computer, etc. Thus, reproduced carpet tiles are produced and subjected a choosing step once again, and the chosen ones are shipped.
