    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.

    Abstract translation: 公开了一种生产地毯的方法，其包括将基于树脂固体的100重量份的背衬材料组合物，其中玻璃化转变点不高于5℃的树脂的水乳液为120℃ 至400重量份的水硬性无机水泥，以及至多600重量份的非水力无机填料在地毯表面基材上，并加热层压板以硬化和干燥背衬材料组合物。 可以容易地获得地毯表面基材和背衬材料（以及如果使用的地毯底基材料）牢固且一体地结合的地毯。 地毯具有良好的平衡性，例如柔软性（柔软性），尺寸稳定性（抗收缩性），适合地板和可加工性等优异性能。 在使用预先涂覆有特定水性树脂乳液的涂料组合物的地毯表面基材时，可以在硬化和干燥中施加较高的温度，这导致生产率的提高，并且所得到的地毯具有优异的绒头拉伸强度。
