  In the present invention, the water-absorbing polyester fiber includes a hydrophilic component in the polyester fiber or on the surface of the polyester fiber. For example, a fiber obtained by melt spinning a polyester containing a hydrophilic component, or a fiber that has been subjected to hydrophilic processing (sweat absorption processing) by post-processing is exemplified. As such hydrophilic processing, 0.25 to 0.50% by weight of the fiber weight is adhered to the fiber weight by the same bath processing or the like when dyeing a hydrophilic agent such as PEG diacrylate and its derivatives or polyethylene terephthalate-polyethylene glycol copolymer. It is preferable to make it.

On the other hand, the water-repellent polyester fiber includes a water-repellent component in the polyester fiber or on the surface of the polyester fiber. For example, a fiber obtained by melt spinning a polyester containing a water repellent component such as a silicone resin or a fluorine resin, or a fiber provided with a water repellent component such as a silicone resin or a fluorine resin on the fiber surface is exemplified.
Here, the content of the water repellent is preferably 0.4% by weight or more (more preferably 0.4 to 10% by weight) relative to the weight of the polyester fiber before processing.

  In that case, it is preferable that the said water repellent is a fluorine-type water repellent whose concentration of perfluorooctanoic acid and perfluorooctane sulfonic acid is 0-5 ng / g. Examples of such a fluorine-based water repellent include perfluoroalkyl acrylate copolymers composed only of monomers not containing an N-methylol group, and commercially available ones. Examples of commercially available products include Asahi Guard E Series AG-E061, a fluorine-based water and oil repellent manufactured by Asahi Glass Co., Ltd., and Scotch Guards PM 3622, PM 490, and PM 930 manufactured by Sumitomo 3M Co., Ltd.

  A method for producing the water-repellent polyester fiber is not particularly limited and may be a known method. For example, as a method for producing a polyester fiber obtained by copolymerizing or blending a silicone compound or a fluorine compound, a method described in JP 2010-138507 A is exemplified. In addition, as a water repellent processing method, for example, a processing agent obtained by mixing a fluorine-based water repellent with an antistatic agent, a melamine resin, a catalyst, or the like as necessary is prepared by using a pad method or a spray method to produce polyester. Examples of the method for imparting to fibers are exemplified.

  In the water-absorbing polyester fiber and / or the water-repellent polyester fiber, the total fineness, single fiber fineness, and number of filaments are 10 to 200 dtex in total fineness in order to obtain excellent deodorization by increasing the surface area of the fiber. It is preferable that the fiber fineness is 5.0 dtex or less (more preferably 0.0001 to 1.5 dtex) and the number of filaments is 30 to 50000 (more preferably 30 to 200).

  The amount of the deodorant is preferably 0.1 to 10% by weight, more preferably 0.25 to 5% by weight, and particularly preferably 0.5 to 3% by weight with respect to the fabric. If it is less than 0.1% by weight, the deodorizing effect may not be exhibited. On the other hand, if it exceeds 10% by weight, the texture may be greatly cured and the durability of the deodorizing action may be reduced.

  The processing of the deodorant can be performed at any stage of raw cotton, yarn and woven or knitted fabric. The processing method can be performed by any method such as a dipping method, a pad dry method, a spray method, a coating method, and a laminating method. It can be appropriately selected depending on the form of the fabric, the resin, and the type of the solution. Moreover, after giving a deodorizer to a fabric, the adhesion state of the deodorizer to a fiber is suitably fixed by heat-processing normally at normal temperature to 180 degreeC for about 1 to 120 minutes.
