を挙げるかが繊維業界の課題であった。2. Description of the Related Art Conventionally, in order to impart various contacting functions to fibers, it has been known that the contacting functional agent is uniformly contained in the artificial fiber.
Here, the contact function means, for example, silver ion released from a silver-based inorganic antibacterial agent has bactericidal properties when contacted with bacteria, aromaticity when perfume molecules contact with olfactory receptors, or malodorous components are airborne. It refers to various functions that are exhibited by molecular / atomic level contact, such as deodorant property that decomposes and becomes odorless by contacting with deodorant together with oxygen in it, and the component that exhibits such performance is called contact functional agent. And In this case, such a contact functional agent is extremely expensive, and further raises the price of the textile product having this kind of function, which is an obstacle to its popularization, so that the desired effect can be obtained in a small amount for cost reduction. The issue was the textile industry.

ある。以下、本発明の実施例を詳細に説明する。In order to achieve the above-mentioned object, the inventors have studied the distribution of the contact functional agent in the fiber cross section and the effect of expressing the function, and as a result, the contact function present in the central portion of the fiber has been investigated. It was found that the effect of the agent was significantly lower than when it was present on the fiber surface. In particular, in the case of spandex fibers having a substantial fineness of more than 10 denier, it has been revealed that the effect of the contact functional agent present in the central portion hardly contributes to the intended function during the practical life of the fiber. It was Based on the above findings, various methods for preferentially distributing the contact functional agent on the surface layer of the spandex fiber were investigated, and the composite fiber of the spandex fiber was spun into two inner and outer layers,
By adding the desired functional contacting agent only to the outer layer, spandex fibers capable of exhibiting a desired function more effectively than the case where the fibers are evenly distributed over the entire cross section are obtained. Hereinafter, examples of the present invention will be described in detail.
