Field of the Invention The present invention relates to an adhesive-treated fiber structure used for reinforcing rubber products such as tires, hoses, conveyor belts, V-belts, power transmission belts, and rubber containers, and a method for producing the same. It is.

Description of the Related Art Conventionally, a method of reinforcing a rubber product with a fiber has been known, and as a method of increasing the adhesive force between the fiber and the rubber at that time, the fiber is previously resorcinol, formalin, latex (hereinafter referred to as RFL). A method of immersing in a liquid, drying and heat-treating is known.

まれている。[0003] Generally, in a fiber reinforced rubber product (rubber composite), the strength and elongation of the fiber for the purpose of reinforcing the rubber product, and the reinforcing fiber and the rubber matrix for the purpose of forming the rubber composite. Adhesive strength is required. Also, since most of the rubber composite is used in an environment that undergoes repeated deformation,
Fatigue resistance to repeated deformation of the fiber itself is required. In recent years, demands for cost reduction and use under more severe conditions have increased, and there is a strong demand for further improvement in the strength and elongation of fiber-reinforced rubber products, improvement in adhesive strength, and improvement in fatigue resistance.

るという問題があった。Further, it has been reported that when the flexibility of the cord is deteriorated, the elongation is reduced and the fatigue resistance is also reduced. Furthermore, when the cord becomes hard, the adhesive falls off in subsequent steps, such as softening and topping to rubber, and the adhesive strength is reduced, the cord becomes curled, the cord is damaged, and the quality is reduced. Also, there is a problem that the strength is reduced.

No. 83, etc.) However, although such a softening treatment has a certain effect, if the ironing tension is increased or the contact portion with the bending agent is made an acute angle in order to further improve the flexibility, There has been a problem that the adhesive itself is scraped off or the cord surface is scratched, and the product itself is physically damaged.

In these cases, even if the fiber structure is improved, there is a problem that the effect of the adhesive used there is great and the fatigue resistance as a final treated fiber is not sufficient.

て何ら妨げになるものではない。[0010] Resorcin, formalin, latex (RFL) used as an adhesive for reinforcing fibers is a mixture of an initial condensate and a rubber latex obtained by reacting resorcin and formalin under an alkali or acidic catalyst. Regarding the mixing ratio of the latex, the effect can be seen by applying any of the known techniques. As the type of latex, any of styrene butadiene latex, vinyl pyridine-containing styrene butadiene latex, chloroprene latex, natural rubber latex, polyethylene latex, nitrile butadiene latex, and the like may be used alone or in combination. Further, at least RFL is used as the fiber adhesive.
The effect is exhibited as long as the compound contains the compound (1), and may be used in combination with an adhesion aid used in polyester, aromatic polyamide, or the like, for example, an epoxy compound, an isocyanate compound, a chlorophenol compound, or the like. The amount of these adhesives adhered to the fibers varies depending on the type of the adhesive, the type of the fiber for reinforcing the rubber, and the compounding of the rubber to be adhered. In the present invention, the solids concentration of the adhesive on the fibers may be optimized depending on the type of the constituent material of the rubber composite used, and the solids concentration of the adhesive on the fibers may be less than that in any case. It does not hinder at all.

い。The alkyl sarcosinate used in the present invention is a reaction product of sarcosine and a fatty acid and is represented by the following chemical formula. R-COCHNH2 COOH (R in the above chemical formula is an alkyl group) Examples of the type of the alkyl group represented by R include a hexyl group, an isohexyl group, a heptyl group, an octyl group, an isooctyl group, a 2-ethylhexyl group, and a decyl group. , Lauryl group, myristyl group, cetyl group, stearyl group, isostearyl group, oleyl group, ricinolein group, palmityl group, propyl group, various mixed alkyl groups, and the like. The ratio of alkyl sarcosinate to RFL in the adhesive is important in the present invention. Although depending on the composition ratio of RFL and the molecular weight of alkyl sarcosinate, the ratio of RFL: alkyl sarcosinate is preferably 0.5% by weight or more to 30% by weight, more preferably 1% by weight, based on the solid content ratio of the adhesive component on the yarn.
15% by weight is preferred. When the solid content ratio of the sarcosine ester compound is small, the modification of the RFL resin obtained in the present invention becomes insufficient, and the intended effect cannot be obtained. On the other hand, if the solid content ratio is too high, the cohesive force of the RFL resin itself decreases, and the adhesive strength becomes insufficient. The alkyl sarcosinate may be present together with the RFL when the RFL causes a cross-linking reaction due to the heat of the treatment to form a three-dimensional structure. Even if the sarcosinate compound is previously applied to the fiber surface, it may be mixed in the RFL solution. Even so, the effect is exhibited. There is no particular limitation on the method of applying the fiber to the fiber in advance, but it is effective in terms of cost to apply the fiber at the spinning stage. Any method such as a method of mixing in a spinning oil agent, a method of separately applying during spinning, and a method of providing a completed yarn with a separate process may be used.

It is recognized that when the product is softened by the softening of the resin, the elongation and fatigue resistance are improved, and the toughness of the resin improves the adhesive strength with the rubber to be adhered. The mechanism by which the RFL resin itself is improved has not been elucidated, but the
When L causes a three-dimensional crosslinking reaction, it is presumed that the matrix is changed to an appropriate state by the incorporation of alkyl sarcosinate inside. It is presumed that just mixing the latex into the epoxy compound resembles the mechanism by which the epoxy resin is made flexible and tough.
