ABSTRACT:
An improved carpet tile for commercial, industrial or home use is disclosed. The carpet tile includes a carpet pile yarn facing portion including a stiffening and stabilizing layer (e.g., glass fiber layer). The backing portion also includes a stiffening and stabilizing layer (e.g., glass fiber layer). Interposed between the facing and backing portions is a stabilizing layer of a mixture of from about 70 to about 90 weight percent non-woven glass fibers and from about 30 to about 10 weight percent of a polyester. The resulting unitary carpet tile shows surprising dimensional stability, stiffness and floor hugging properties even during periods of concentrated stress, and passes rigorous flame retardancy and smoke emission tests.
