が煩雑となり、このためその改良が望まれていた。In conventional two-step processing methods, the nonwoven fibers or pile yarns are fixed by coating or impregnating with an adhesive consisting of a styrene-butadiene copolymer latex or an aqueous emulsion of a resin, and then backed with a thermoplastic resin film. This gives the carpet thermoformability, but such a two-step processing method complicates the carpet manufacturing process, and therefore improvements have been desired.

の固着力が低下してしまうという問題があった。On the other hand, the one-step processing method that imparts thermoformability to the adhesive without backing with a thermoformable resin film, as described above, improves thermoformability, the ability to maintain its shape (shape retention), and the quality of the product. The required hard feel (rigidity) is insufficient, and if attempts are made to improve the thermoformability, shape retention, and rigidity, there is a problem in that the adhesion of the fibers decreases.
従って、熱成型性、保型性、剛性、繊維の固着力の全て
