DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber fabric which gives a refreshing feeling by adding mint oil and / or l-menthol.

[0002]

2. Description of the Related Art Synthetic fibers such as polyester and nylon are widely used because of their excellent physical and chemical properties, but they have low hygroscopicity and easily stuffy when worn. In addition, there is a disadvantage that it is easily charged, and improvement is desired.

For this reason, as disclosed in Japanese Patent Publication No. Sho 60-34979, acrylic acid or methacrylic acid is graft-polymerized onto synthetic fibers. A method has been proposed in which a hydrophilic monomer is polymerized on a polyester fiber.

[0004] However, these methods have the drawbacks that the performance and durability are insufficient and the hand becomes hard.

As a method of applying microcapsules to fibers, a method of immersing microcapsules containing a fragrance and a gum arabic paste in a woven fabric is disclosed in JP-A-49-1.
No. 9197 discloses a method for printing carboxymethylcellulose-based microcapsules containing a fragrance.
JP-A-3-47440 discloses a method in which a fragrance is adsorbed on a polyamide resin and silica gel, and a method of applying the fragrance to fibers with a vinyl binder is described in JP-A-53-52561. The method is described in JP-A-58-4886.

[0006] However, if the stocking is processed by the conventional technique of providing these microcapsules, there are problems such as clogging of stitches, hardening of texture, and deterioration of stretchability.

Japanese Patent Application Laid-Open No. 1-250101 discloses a method of applying microcapsules containing a fragrance to a stocking together with a silicone-based binder, and Japanese Patent Application Laid-Open No. 1-292183 discloses a method of using a formalin-based microcapsule containing a fragrance and a silicone-based binder. As described in the official gazette, there are problems in the exhaustion of the scented capsule and the slipperiness when worn.

[0008] In order to solve these drawbacks, vinyl carboxylic acid and / or vinyl carboxylic acid have been used as a method for obtaining a durable fiber material having moisture absorption / desorption properties, antistatic properties and a soft texture.
Alternatively, a method of polymerizing a treatment liquid containing a vinyl sulfonic acid monomer on the surface of a fiber material has been proposed in Japanese Patent Application Laid-Open No. 8-209540. According to this method, durable hygroscopicity and antistatic property were obtained, but a refreshing sensation was not obtained only with hygroscopicity.

[0009]
