〈実施の態様〉
本発明の方法をよりよく理解するために、本発明の実施
の態様を以下に説明をする（第１図参照）。<Embodiments> In order to better understand the method of the present invention, embodiments of the present invention will be described below (see FIG. 1).
（１）ＥＰＲ製のゴム成形品本体１表面にプライマー処
理後、軟質のウレタン塗１Ｉｉ５を形成する。(1) After primer treatment, a soft urethane coating 1Ii5 is formed on the surface of the EPR rubber molded body 1.
■ゴム成形品は、通常、圧縮・射出・トランスファ成形
等の型成形によるが、押出成形品であってもよい。第１
表に、射出成形用のＥＰＤＭ配合処方の一例を示す。■Rubber molded products are usually molded by compression, injection, transfer molding, etc., but may also be extrusion molded products. 1st
The table shows an example of an EPDM formulation for injection molding.
■通常、ゴム成形品本体は、アルコール等で脱脂処理を
しておく、さらに、ゴム成形品が非極性材料であるＥＰ
Ｒ製であるため、ゴム成形品本体は、プライマー処理を
しておく、即ち、プライマー層３を形成しておく必要が
ある。■Normally, the rubber molded product body is degreased with alcohol, etc., and the rubber molded product is made of non-polar material.
Since it is made of R, the rubber molded product body needs to be treated with a primer, that is, a primer layer 3 needs to be formed in advance.
当該プライマーとして、塩素化ポリプロピレン又はアク
リル変性ＥＰＤＭを含有する溶液形のものを使用する。As the primer, a solution type primer containing chlorinated polypropylene or acrylic modified EPDM is used.
これは、本発明の最大特徴の−っである。This is the most important feature of the present invention.

形品においては、必然的となる。■As the urethane paint that forms the urethane coating 5,
Either one-component type such as oil modified type, moisture curing type, block type, or two-component type such as catalyst curing type or polyol curing type may be used.
From the viewpoint of coating performance, a polyol-cured isocyanate component is preferred.The isocyanate component of the urethane paint is preferably an aliphatic or cyclic type, so-called non-yellowing one. This is especially true for rubber molded products that are used outdoors and are often exposed to ultraviolet rays and the like.
なお、このウレタン系塗料には、通常、者色剤、乾燥剤
、増粘剤、レベリング剤、紫外線吸収剤が適宜配合され

選択して使用をするまた、このウレタン塗膜の軟質の程
度は、通常、引張り伸張度で５０％以上とする。塗布方
法は、特に限定されず、刷毛塗り、フローコート、ロー
ルコート、スプレー塗布等、適宜選択して使用する。Note that this urethane paint usually contains a coloring agent, a desiccant, a thickener, a leveling agent, and an ultraviolet absorber as appropriate. In addition, as the solvent, one or more solvents are usually selected from aromatic, aliphatic, ester, and ketone solvents.Also, the degree of softness of the urethane coating is usually determined by: The tensile elongation should be 50% or more. The coating method is not particularly limited, and may be appropriately selected and used, such as brush coating, flow coating, roll coating, and spray coating.
この、ウレタン塗膜の膜厚は、通常、乾燥膜厚１０〜１
００μｍとする。膜厚が、１０μｍ未満ては、次のパイ
ル起毛層７を形成する際のパイルの起毛性（直立性）が
良好でなく、さらには、成形品にソフトな触感を付与し
がたい。The film thickness of this urethane coating film is usually a dry film thickness of 10 to 1
00 μm. If the film thickness is less than 10 μm, the pile raising properties (uprightness) when forming the next pile raised layer 7 will not be good, and furthermore, it will be difficult to impart a soft feel to the molded product.
（２）続いて、上記ウレタン塗膜が乾かないうちに、下

ル起毛層（植毛層）７を形成する。(2) Next, before the urethane coating film dries, a dispersion having the following composition is spray coated to form a pile raised layer (flocked layer) 7.
即ち、パイルを部分埋設して固定することによりパイル
起毛層７を形成する。That is, the pile raised layer 7 is formed by partially embedding and fixing the pile.

方式を問わないが、パイル起毛性の見地からは、エア方
式が好ましい。Thereafter, the drying may be carried out at room temperature, but from the viewpoint of productivity, drying is usually carried out for a period of 60 to 100 m depending on the heat resistance temperature of the pile. Note that the spray coating method may be air or airless, but from the viewpoint of pile raising properties, air method is preferable.
分散液組成。Dispersion composition.

適宜添加する。Thickness: 05-3.0 denier (D), length: 0.1-2
1 to 20% of a pile of mm in diameter is added and dispersed in a solvent. Auxiliary materials such as ultraviolet absorbers and thickeners are appropriately added to this dispersion.
また、溶剤は、特に限定されないが、ウレタン塗膜に対
する密着性の見地から、前述のウレタン系塗料に使用し
たものと同系のものを使用可能である。Further, the solvent is not particularly limited, but from the viewpoint of adhesion to the urethane coating, those of the same type as those used for the above-mentioned urethane paint can be used.
パイル太さ及び長さが上記数値より小さいと、それぞれ
、パイルのウレタン塗膜面５ａからの直立性が弱く、ま
た、ウレタン塗膜面５ａからの突出長さが小さくなるた
め、フアブリツク感の増大要素である嵩高性が低減して
望ましくない。上記数値より大きいと、スプレーガンが
つまりやすくスプレー塗装が困難となる。If the pile thickness and length are smaller than the above values, the uprightness of the pile from the urethane coating surface 5a will be weak, and the length of the pile protruding from the urethane coating surface 5a will be small, resulting in an increased fabric feeling. This is undesirable because the bulkiness, which is a factor, decreases. If it is larger than the above value, the spray gun is likely to become clogged and spray painting becomes difficult.
また、パイルの添加量が、１％未満では、ゴム成形品表
面のパイル密度が粗となり、ゴム成形品表面にフアブリ
ツク感を付与しがたく、２０％を超えると、上記同様、
スプレーガンがつまりやすく、スプレー塗布が困難とな
る。In addition, if the amount of pile added is less than 1%, the pile density on the surface of the rubber molded product becomes rough, making it difficult to impart a fabric feel to the surface of the rubber molded product, and if it exceeds 20%, as above,
Spray guns tend to clog, making spray application difficult.
パイルの材質は、ポリエステル・レーヨン・ナイロン系
等のものを使用するが、溶剤への分散性、ウレタン塗膜
に接着性の見地からナイロン繊維系のものが望ましい。The material used for the pile is polyester, rayon, nylon, etc., but nylon fiber is preferable from the viewpoint of dispersibility in solvents and adhesion to urethane coatings.

の間に、実用に耐える十分な密着強度を得られる。(1) Adhesion strength sufficient for practical use can be obtained between the EPR base material (rubber molded product body) and the urethane coating film.
（２）パイル起毛層を形成する分散液が樹脂分を含まな
いので、従来の如く、パイル全体が埋設してしまう部位
が発生することがなく、良好な風合のパイル起毛層を安
定して得られる。(2) Since the dispersion liquid that forms the pile raised layer does not contain resin, there is no part where the entire pile is buried, unlike in the past, and it is possible to stably create a pile raised layer with a good texture. can get.
