Abstract
A dimensionally stable carpet tile having a greige good adhered to an aqueous wet-laid composite sheet comprising a dimensionally stable reinforcing fiber in an amount sufficient to provide less than a 0.1 percent dimensional change of the carpet on an Aachen Test. Typical dimensionally stable reinforcing fibers are glass fibers and/or polyester fibers employed in amounts from about 2 to about 15 percent by weight based on the total composite sheet. The other main ingredients of the composite sheet comprise from about 1 to about 30 percent cellulose fibers, 2 to about 30 percent organic polymer binder material and 60 to 95 percent inorganic filler based on the total weight composite sheet. The composite sheet has an internal bond strength of at least 50 grams per inch.
