れていた。Conventional technology> Synthetic fibers have been used as nonwoven fabric materials due to their high strength, acid resistance, alkali resistance, oil resistance, water resistance, etc., but synthetic fibers are mainly composed of hydrophobic resin fibers. The field of use of the nonwoven fabrics produced by this method is limited due to their lack of hydrophilicity, and a method for imparting hydrophilicity to these nonwoven fabrics has been desired.

が行なわれている。Conventional methods for imparting hydrophilicity to nonwoven fabrics include treating the surface of hydrophobic fibers with a surfactant (oil agent), and using materials in which hydrophilic groups are introduced into hydrophobic materials through graft copolymerization or block copolymerization. In particular, a hydrophilic resin and a hydrophobic resin are mixed and spun in an appropriate ratio, or a hydrophilic fiber material is blended with a hydrophobic fiber material.

のある親水性を有するに至らない。Problems to be Solved by the Present Invention When hydrophobic fiber materials are treated with an oil agent to introduce hydrophilic functional groups, the binding force between the fibers and the oil agent is weak, making it difficult to obtain hydrophilic properties that are resistant to washing. do not have.
即ち油剤処理した不織布を洗濯するとき、親水性を付与
していた油剤が疎水性繊維から洗浄除去されてしまう。That is, when a nonwoven fabric treated with an oil agent is washed, the oil agent that imparts hydrophilicity is washed away from the hydrophobic fibers.

する。In addition, when a hydrophilic group is introduced into a hydrophobic resin by copolymerization, or when a hydrophilic resin and a hydrophobic resin are mixed and used, the purpose is sufficiently achieved, but the result is an expensive nonwoven fabric. Furthermore, when a hydrophilic material is mixed with a hydrophobic fiber material, there is a drawback that the hydrophobic fiber portion remains hydrophobic. An object of the present invention is to provide a nonwoven fabric that is mainly composed of a hydrophobic resin and has been given hydrophilicity with good washing resistance by subjecting the nonwoven fabric to simple post-treatment.

発明を完成するに至った。<Means for Solving the Problems> The above object of the present invention is achieved by providing a nonwoven fabric mainly composed of hydrophobic fibers, characterized in that at least one side of the nonwoven fabric is subjected to a corona discharge treatment. That is, the present inventors found that it is possible to impart hydrophilicity to nonwoven fabrics by subjecting them to corona discharge treatment, and that surface modification of fibers by corona discharge treatment can provide hydrophilic durability with washing resistance. The present invention was completed based on the discovery that the present invention can be achieved.

るものと考えられる。The reason why the nonwoven fabric made of the hydrophobic fibers of the present invention becomes hydrophilic when subjected to the corona discharge treatment is not clearly understood, but it is thought to be as follows. When the nonwoven fabric passes through a place where corona discharge is occurring, the impact of charged particles from the electrodes, the local heat generation effect, or the generated substances in the discharge space or the products on the surface of the nonwoven fabric cause
An oxidation reaction progresses on the surface of the polymer hydrocarbon of the nonwoven fabric with the involvement of oxygen in the air. At that time, it is thought that hydrophilicity is imparted to the surface of the polymer hydrocarbon by the generation and introduction of hydrophilic groups such as carbonyl groups, carboxy groups, hydroxy groups, and the like.

セパレーター材が得られる。The nonwoven fabric used in the present invention may be manufactured by any method. The nonwoven fabric of the present invention, such as disposable diapers, sanitary napkin facings, and second sheet water absorption layers, is required to have the ability to quickly transmit water, and the corona discharge treated nonwoven fabric of the present invention satisfies this required property. It is. In addition, battery separator materials are required to have acid and alkali resistance, and polyolefin nonwoven fabrics, for example, are suitable for this purpose, but they have the drawback of insufficient liquid retention and absorption properties due to their hydrophobic nature. had. When this polyolefin nonwoven fabric is subjected to a corona discharge treatment, the above-mentioned drawbacks are eliminated and a good battery separator material can be obtained.

In medical gowns, scenes, drapes, etc., it is preferable to use hydrophilic material on the surface that comes into contact with the body and make the outside hydrophobic from the standpoint of bacterial barrier properties, but it is more advantageous to use the same material when bonding these materials. be.
