【産業上の利用分野】本発明は、天然ゴム製の作業用手

分な保温用起毛を有し、天然ゴムを基体とする起毛製品
およびその製造法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brushed product such as work gloves and boots made of natural rubber, and more particularly, to a brushed product having a sufficient brush for keeping heat on its inner surface and using natural rubber as a base material. It relates to the manufacturing method.
【０００２】[0002]
【従来の技術】作業用手袋、長靴等には、保温性を向上
させるため、パイルを用いて内面に起毛処理を行なうこ
とが多く、塩化ビニルを基体とする作業手袋や長靴では
当然のこととして植毛密度の高い起毛処理が行なわれて
いる（以下、起毛処理が行なわれた作業用手袋、長靴等
を「起毛製品」ということがある）。2. Description of the Related Art Work gloves, boots and the like are often brushed on the inner surface using a pile in order to improve heat retention, and as a matter of course, work gloves and boots using vinyl chloride as a base material. Brushing treatment with a high flocking density is performed (hereinafter, working gloves, boots, and the like on which the brushing treatment has been performed may be referred to as “brushed products”).
【０００３】しかし、天然ゴムを基体とする作業用手
袋、長靴等では、実際上、内面を高い植毛密度で起毛処
理を行なってもパイルの接着強度が弱く、簡単にパイル
が取れてしまうので、起毛処理を施されることはあまり
多くなかった。However, in the case of working gloves, boots and the like using a natural rubber as a base, even if the inner surface is brushed at a high flocking density, the pile adhesive strength is weak and the pile can be easily removed. Not very often brushed.
【０００４】基体が天然ゴムである作業用手袋や長靴に
おいて、あまり高い植毛密度で起毛処理が行なわれない
理由は次の通りである。 すなわち、植毛のためには、
パイルを接着するための接着剤を用いることが必要であ

接着剤として用いざるをえない。 しかし、この天然ゴ
ムは、レーヨン、コットン等の植毛パイルとの接着性が
十分でなく、使用中に植毛したパイルが取れ易いという
欠点があった。[0004] In working gloves and boots in which the base is natural rubber, the reason why the raising treatment is not performed at an excessively high flocking density is as follows. That is, for flocking,
It is necessary to use an adhesive to bond the pile, but if something other than natural rubber is used as the flocking adhesive, delamination or cracking of the adhesive will occur, so natural rubber must be used as the adhesive I can't get it. However, this natural rubber has a disadvantage that the adhesiveness with a flocked pile of rayon, cotton or the like is not sufficient, and the pile that has been flocked during use is easily removed.
【０００５】このような理由から、天然ゴムを基体とす
る作業用手袋や長靴には、ほとんど高植毛密度での起毛
処理が行なわれていなかった。[0005] For these reasons, working gloves and boots made of natural rubber as a base have not been subjected to a raising treatment at a high flocking density.

ていた。However, even in working gloves and boots using natural rubber as a base, it is necessary to raise the inner surface of the gloves with a high flocking density. There has been a demand for the development of a brushed product with a high flocking density.

うることを見出した。Means for Solving the Problems The inventors of the present invention have conducted intensive studies to obtain a brushed product having an excellent texture of natural rubber and having an inner surface uniformly implanted at a high flocking density. If an anchor coat layer which is a polymer layer selected from urethane resin, modified rubber and epoxy resin having an affinity for both layers is provided between the base layer and the adhesive layer, It has been found that even if a material other than natural rubber is used, problems such as delamination and cracking of the adhesive layer do not occur. Then, they have found that if an acrylic adhesive widely used in brushed products made of vinyl chloride is used as the adhesive, the pile can be uniformly implanted with high adhesive strength and high flocking density.

It is intended to provide a natural rubber glove or boots provided with a car coat layer and an acrylic adhesive layer, and a pile planted in the acrylic adhesive layer, and a method for producing the same.

植毛すれば良い。In the brushed product made of natural rubber according to the present invention, an anchor coat layer having an affinity for both the base layer and the adhesive layer is provided on a base layer formed of natural rubber,
Further, after providing the acrylic adhesive layer, the hair may be implanted according to a conventional method.

The hand mold is pulled up, dried and formed into a film, then immersed in warm water to elute and remove the coagulant, thereby forming a natural rubber substrate on the mold. As the coagulant, a compound that coagulates latex particles such as calcium nitrate and calcium chloride is used.

It is performed by drying for about 1 to 10 minutes. Generally, the thickness of the anchor coat layer may be about 10 to 100 μm.

By drying at 0 ° C. for 2 minutes and then implanting the pile by an electrostatic flocking method applying a high voltage of, for example, about 30,000 V,
A flocking product with a high density of flocking is obtained. As a pile used for flocking, fibers such as rayon and cotton having a thickness of about 0.5 to 1.5 denier and a length of about 0.3 to 1.0 mm are used.

があった。The conventional natural rubber adhesive has a remarkably weak adhesive strength to the pile and can be easily removed even if the flocking density is increased, so that the electrostatic flocking method could not be practically used. Therefore, the flocking method has been employed to carry out the flocking, but in this case, there is a disadvantage that the flocking density cannot be increased.

For example, an acrylic adhesive can be used, and as a result, for the first time, high-density flocking can be achieved in a natural rubber flocking product.
