In order to impart thermoformability, it is manufactured using a two-step processing method in which a thermoplastic resin film such as polyethylene is lined by heat fusion.

の改良が望まγしていた。In the conventional two-step processing method, nonwoven fibers or piles are fixed by coating or impregnation 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. However, such a two-step processing method complicates the carpet manufacturing process, and therefore improvements have been desired.

開発が望ま几ていた。On the other hand, various one-step processing methods have been attempted in which the aqueous emulsion has both the roles of fixing the fibers and imparting thermoformability, and the emulsion is merely coated or impregnated with a coating. However, with conventional one-stage processing technology, thermoformability and the ability to maintain its shape (also referred to as shape retention) are insufficient, and efforts have been made to improve this thermoformability and shape retention. Thirdly, there was a problem in that the adhesion of the fibers decreased. Therefore, it has been desired to develop a backing adhesive composition for one-stage processing that is excellent in all aspects of thermoformability, shape retention, and fiber adhesion.

It is composed of monomer components mainly composed of methyl styrene, methyl methacrylate, etc., and is combined with a small amount of unsaturated carboxylic acid that can be combined with monomers such as Kakkō and Kakkō. Furthermore, the glass transition point can be adjusted. Therefore, it is an aqueous synthetic resin emulsion made by copolymerizing a small amount of monomers such as butadiene, butyl acrylate, 2-ethylhexyl acrylate, etc. Especially preferred is one in which styrene is copolymerized with a small amount of unsaturated carboxylic acid and butadiene. . Also,
Synthetic resin emulsion (glass transition point of AJ is 80~
If the glass transition point is less than 80°C, the thermoformability and shape retention will deteriorate, and if it exceeds 110°C, the adhesion of the fibers will decrease, which is not preferable.

Preferably, it is a rubber latex in which a small amount of unsaturated carboxylic acid copolymerizable with these monomers is copolymerized. In particular, a synthetic rubber latex consisting of a ternary copolymer of styrene-butadiene-unsaturated carboxylic acid is most preferred. In addition, the glass transition point of the synthetic rubber latex (B) is -50 to θ℃
If the glass transition point is lower than 150°C, the thermoformability and shape retention will deteriorate, and if it exceeds 0°C, the adhesion of the fibers will decrease, which is not preferable.

て具備している。○: No adhesive falling off, good pilling Δ: Some adhesive falling off, pilling slightly bad Adhesive compositions ① to ① were obtained by carrying out the same operations as in Example 1 except that the mixing ratio of B) and the amount of crosslinking agent (C) added were changed as shown in Table 1. Thereafter, the same operations and tests as in Example-1 were performed, and the results are shown in Table-1. The specific adhesive composition of the present invention, which is obtained by mixing a synthetic rubber latex with a low carbon content and adding a crosslinking agent to the mixture, has the moldability, shape retention, and fiber hardness required for automobile carpets. The adhesive composition of the present invention can simultaneously develop adhesive strength, and can omit the two-step processing technology step of backing with a thermoplastic resin film, which simplifies the carpet manufacturing process and improves productivity. It also has sound effects.
