ABSTRACT:
The invention comprises an improved recycling and recovery process for rugs, flooring, carpeting, carpeting materials, and other textiles particular from waste carpet containing at least some synthetic fiber backing materials, and at least some nylon as well, and more particularly for the separation and recovery of the nylon polymers in purified and reusable condition and also recovery of other polymeric fibers and materials which may be present and can be recycled and reused.
