が行われている。2. For needle-punched carpets and tufted carpets for automobile interiors, an adhesive composition mainly composed of styrene-butadiene copolymer latex or ethylene-vinyl acetate resin emulsion is applied or impregnated on the back surface of the carpet. After processing, a two-stage processing method is used in which the material is lined with a thermoplastic resin film such as polyethylene by heat fusion.

開示されている。Furthermore, Japanese Patent Application Laid-Open No. 58-52776 discloses a so-called one-step processing method in which a carpet that can be continuously molded is obtained by applying an aqueous plastic dispersion to the back surface of the carpet.

ているが、この様な２段加工法はカーペットの製造工程
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.

の開発が望まれてい ｔこ 。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 texture (rigidity) was insufficient, and if attempts were made to improve this thermoformability, shape retention, and rigidity, there was a problem that the adhesion of the fibers would decrease.
It is desired to develop an adhesive composition that has thermoformability for one-stage processing and is excellent in all aspects of thermoformability, shape retention, rigidity, and fiber adhesion.

The fact that by using a mixture obtained by mixing (b) at a certain ratio as an adhesive, it exhibits excellent effects in all aspects of thermoformability, shape retention, rigidity, and fiber adhesion. They discovered this and completed the present invention.

In contrast, antioxidant (Sumilyzer S: Sumitomo Chemical Co., Ltd.
(manufactured by Kao Corporation) and 1 part of a surfactant (Emar 2FN, manufactured by Kao Corporation) were added to obtain an adhesive composition with a solid content of 47%. Each of the obtained adhesive compositions was whipped to 3 times the volume in a Hobart mixer and applied to the back side of a polypropylene-polyester blend needle punch carpet.
It was applied in a coating amount of 100 ml, and was impregnated to the inside. Thereafter, the carpet samples obtained by drying at 130°C for 5 minutes were tested for moldability, shape retention, rigidity, and fiber fixation strength based on the following measurement methods.
