Abstract
The present invention pertains to carpet and methods of making and recycling carpet. In one aspect, the carpet includes: a primary backing which has a face and a back surface; a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing; an adhesive composition backing; and an optional secondary backing adjacent to the adhesive backing. The method of making carpet includes extrusion coating the adhesive composition onto the back surface of a primary backing to form the adhesive composition backing. The method of recycling carpet can recover one or more polymeric carpet components.
Claims25
A carpet composition, comprising:
- a primary backing;
- a plurality of carpet fibers, the plurality of carpet fibers penetrating a bottom surface of the primary backing and protruding therefrom a top surface of the primary backing, and
- an adhesive backing connected to the bottom surface of the primary backing and comprising an adhesive composition, wherein the adhesive composition comprises:
- i) an optional tackifier in amount, when present, of from 5 wt. % to 45 wt. %., and
- ii) a recycled polymer composition reclaimed from a terpene solvent solution, wherein the recycled polymer composition comprises greater than 0% to 0.26% of a residual terpene solvent.
