近年、合成繊維からなる織布、不織布等の合成繊維構造物は、通気性、柔軟性に優れることから各種用途に幅広く用いられている。そのため、合成繊維構造物には、その用途に応じた各種の特性が求められるとともに、その特性の向上が要求されている。 In recent years, synthetic fiber structures such as woven fabrics and nonwoven fabrics made of synthetic fibers have been widely used for various applications because of their excellent breathability and flexibility. For this reason, synthetic fiber structures are required to have various properties according to their use and to improve the properties.
また、合成繊維からなる織布、不織布等の合成繊維構造物は、一般に疎水性であり、親油性を有している。また、疎水性は有しているものの、撥水性は不十分である。
合成繊維構造物に撥水性を付与する方法として、合成繊維構造物をカチオン系帯電防止剤、アニオン系帯電防止剤及びフッ素系撥水剤を一浴に含む処理液で処理する方法（特許文献１：特公平２−５５５５０号公報）、合成繊維構造体を、撥水剤、アニオン系帯電防止剤及び架橋剤で処理する方法（特許文献２；特開平１１−１８９９７６号公報）等種々の方法が提案されている。
Synthetic fiber structures such as woven fabric and nonwoven fabric made of synthetic fibers are generally hydrophobic and oleophilic. Moreover, although it has hydrophobicity, its water repellency is insufficient.
As a method for imparting water repellency to a synthetic fiber structure, the synthetic fiber structure is treated with a treatment liquid containing a cationic antistatic agent, an anionic antistatic agent and a fluorine-based water repellent in one bath (Patent Document 1). : Japanese Patent Publication No. 2-55550), and a method of treating a synthetic fiber structure with a water repellent, an anionic antistatic agent and a crosslinking agent (Patent Document 2; JP-A-11-189976). Proposed.
しかしながら、合成繊維構造物に撥水性を付与することは容易であるが、特にポリプロピレン等のポリオレフィンからなる繊維は親油性に優れることから、撥油性をも付与することは困難である。 However, it is easy to impart water repellency to the synthetic fiber structure, but it is difficult to impart oil repellency because fibers made of polyolefin such as polypropylene are particularly excellent in lipophilicity.
本発明は、撥アルコール性及び撥油性に優れ、且つ耐水性を有する合成繊維構造物を開発することを目的とする。 An object of this invention is to develop the synthetic fiber structure which is excellent in alcohol repellency and oil repellency, and has water resistance.
本発明は、フッ素系撥水剤の付着量が、１〜５ｇ／ｍ2、およびノニオン系帯電防止剤の付着量が０．２〜１．０ｇ／ｍ2の範囲にあるポリプロピレン不織布からなる合成繊維構造物に係る。 The present invention, the adhesion amount of the fluorine-based water repellent, amount of adhesion of 1 to 5 g / m 2, and nonionic antistatic agents of polypropylene nonwoven fabric in the range of 0.2 to 1.0 g / m 2 Synthesis Related to fiber structures.
本発明の合成繊維構造物は、撥アルコール性及び撥油性に優れており、且つ耐水性を有するので衛生材料、医療用材料、衣料用材料等に好適に用い得る。 The synthetic fiber structure of the present invention is excellent in alcohol repellency and oil repellency, and has water resistance, so that it can be suitably used for sanitary materials, medical materials, clothing materials and the like.
