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.
Claims5
A method for manufacturing carpet tiles having excellent dimensional stability comprising the steps of:
- (a) allowing a reticulated glass fiber base having a small thermal coefficient of linear expansion and an opening ratio of 33 to 95% and a unit weight of 73 to 225 g/m.sup.2 to contact with the whole surface of the back of a tufted or needle-punched carpet base material in order to form a composite material, and,
- (b) thermally melting a backing material prepared from a composition containing as the major component, a thermoplastic material selected from the group consisting of asphalt, polyolefin and olefin-polar monomer copolymer, and applying the melted material to the composite material on the side of the reticulated fabric base thereof by T-die extrusion.
