ABSTRACT:
A process for producing a carpet is disclosed, comprising laminating a backing material composition comprising 100 parts by weight, on a resin solid basis, of an aqueous emulsion of a resin having a glass transition point of not higher than 5.degree. C., from 120 to 400 parts by weight of hydraulic inorganic cement, and up to 600 parts by weight of a non-hydraulic inorganic filler on a carpeting surface base material and heating the laminate to harden and dry the backing material composition. A carpet in which a carpeting surface base material and a backing material (and a carpeting back base material, if used) are firmly and integrally bonded can easily be obtained. The carpet has excellent properties, such as flexibility (softness), dimensional stability (resistance to shrinkage), fit to a floor, and workability, in a good balance. Where a carpeting surface base material previously coated with a coating composition comprising a specific aqueous resin emulsion is used, a higher temperature can be applied in hardening and drying, which leads to increased productivity, and the resulting carpet has excellent pull strength of pile.
