Abstract
Abstract The present invention relates to a method for manufacturing carpet tiles having excellent dimensional stability which comprises the steps of: (a) allowing a reticulated fabric base having a small thermal coefficient of linear expansion to be contact with the whole surface of the back of a carpet base material, (b) applying a backing material prepared from a composition containing a thermoplastic material as the major component to the resulting composite material, and (c) optionally laminating a fabric backing onto the above backing material.
