Description
本発明は、合成繊維用処理剤及び合成繊維に関する。詳しくは、合成繊維の製糸工程において良好な工程通過性を発揮し、後加工の工程において良好なゴム接着性を有する合成繊維用処理剤及び、かかる合成繊維用処理剤が付着した合成繊維に関する。 The present invention relates to a treatment agent for synthetic fibers and synthetic fibers. More specifically, the present invention relates to a synthetic fiber treatment agent that exhibits good process passability in a synthetic fiber yarn-making process and has good rubber adhesiveness in a post-processing process, and a synthetic fiber to which such a synthetic fiber treatment agent is attached.
近年、合成繊維の紡糸工程や加工工程においては、高速化が進み、これに伴って毛羽や糸切れが起こりやすくなっている。そのため、これらを抑制する合成繊維用処理剤として、多価アルコールにポリオキシアルキレン基を付加したポリエーテルを含有するもの（例えば、特許文献１、２）や、特異的な構造を持つ有機亜鉛化合物を含有するもの（例えば、特許文献３）等が提案されている。しかし、これら従来の合成繊維用処理剤には、繊維間への合成繊維用処理剤の浸透性が不足し、紡糸時や加工時に毛羽や断糸を十分に抑制することができないという問題があった。
一方、得られた合成繊維は産業資材としても多く利用されており、中でも、タイヤ類、ベルト類、ホース類等のゴム製品の補強材として汎用されている。これらのゴム製品は、合成繊維製の撚糸を接着剤で処理した補強用コードで補強されており、この補強用コードは、ゴム製品の耐久性を向上するため、ゴムに対する充分な接着性を有することが要求される。この要求を満たすために合成繊維用処理剤が使用され、多価アルコール及び／又は多価カルボン酸にポリオキシアルキレン基を付加した化合物を含有するもの（例えば、特許文献４）等が提案されている。しかし、これら従来の合成繊維用処理剤を付着した合成繊維を、接着剤で処理した補強用コードは、ゴム接着性が十分ではないという問題があった。
In recent years, in the spinning process and processing process of synthetic fibers, the speed has been increased, and fluff and yarn breakage are likely to occur accordingly. Therefore, as a treatment agent for synthetic fibers that suppresses these, those containing a polyether in which a polyoxyalkylene group is added to a polyhydric alcohol (for example, Patent Documents 1 and 2) and an organozinc compound having a specific structure are used. (For example, Patent Document 3) and the like containing the above have been proposed. However, these conventional treatment agents for synthetic fibers have a problem that the permeability of the treatment agent for synthetic fibers between fibers is insufficient, and fluff and yarn breakage cannot be sufficiently suppressed during spinning and processing. rice field.
On the other hand, the obtained synthetic fibers are widely used as industrial materials, and among them, they are widely used as reinforcing materials for rubber products such as tires, belts and hoses. These rubber products are reinforced with a reinforcing cord made of synthetic fiber twisted yarn treated with an adhesive, and this reinforcing cord has sufficient adhesiveness to rubber in order to improve the durability of the rubber product. Is required. In order to satisfy this requirement, a treatment agent for synthetic fibers is used, and those containing a compound in which a polyoxyalkylene group is added to a polyhydric alcohol and / or a polyvalent carboxylic acid (for example, Patent Document 4) have been proposed. There is. However, the reinforcing cord obtained by treating the synthetic fiber to which the conventional synthetic fiber treatment agent is attached with an adhesive has a problem that the rubber adhesiveness is not sufficient.
本発明は、耐毛羽性に優れた良好な紡糸性が得られ、かつ、補強用コードとした際に良好なゴム接着性が得られる合成繊維用処理剤と、この合成繊維用処理剤が付着した合成繊維を提供することを課題としている。 In the present invention, a treatment agent for synthetic fibers, which can obtain good spinnability with excellent fluff resistance and good rubber adhesiveness when used as a reinforcing cord, and a treatment agent for synthetic fibers adhere to each other. The subject is to provide the synthetic fiber.
本発明者は上記課題を解決するために鋭意研究を重ねた結果、補強用コードとした際に良好なゴム接着性を得るためには、特定の化学構造を有するエーテルエステル誘導体が合成繊維用処理剤の繊維への均一付着に関与していることを見出し、上記課題を解決するに至ったものである。 As a result of intensive research to solve the above problems, the present inventor has treated an ether ester derivative having a specific chemical structure for synthetic fibers in order to obtain good rubber adhesiveness when it is used as a reinforcing cord. They have found that they are involved in the uniform adhesion of the agent to the fibers, and have solved the above-mentioned problems.
