水性を確保することはできなかった。2. Description of the Related Art Conventionally, many studies have been conducted on a polyester fiber to enhance its deep hue and bathochromic property. For example, it is a method of forming fine irregularities on the fiber surface to prevent irregular reflection of light on the fiber surface. More specifically, for example, a method of previously adding a fine pore-forming agent to polyester fibers and then removing the fine pore-forming agent by alkali treatment (Japanese Patent Laid-Open No. 54-120728, etc.).
Another method is to form fine irregularities by plasma etching the fiber surface (Japanese Patent Publication No. 60-37225, etc.). However, the bathochromicity is improved by the fine irregularities on the fiber surface, but since the fine irregularities on the fiber surface are easily destroyed, for example, when the fabrics are rubbed together or the fabric is entangled in the laundry, the bathochromic effect is obtained. There was a problem that it would drop extremely. Further, although the water absorption is slightly improved by the presence of the fine pores, sufficient water absorption cannot be secured by itself.

いう問題があった。On the other hand, as another method for improving the bathochromic property, there is known a method of coating the fiber surface of a colored fiber cloth with a compound having a refractive index lower than that of polyester fibers such as a silicone type treating agent and a fluorine type treating agent. Has been. However, since the polyester fibers have low hydrophilicity and these treatment agents have water repellency, there is a problem that the sticky feeling during sweating cannot be suppressed.

Acrylic ester resins are preferred. Polydimethylsilane, polymethylhydrogen siloxane, polydimethylsiloxane, etc. are used as the silicone resin, and polypentadecafluorooctyl acrylate, polytetrafluoroethylene, polytrifluoroethyl acrylate, etc. are used as the fluorine resin. The resin is a block copolymer of propylene oxide and ethylene oxide or random copolymer polyether diol and hexamethylene diisocyanate, etc., as the acrylic ester resin is polyethyl acrylate,
Examples thereof include polyethylmethacrylate. Further, since the refractive index of the polyester fiber is about 1.6 to 1.7, the refractive index is preferably 1.5 or less,
Further, it is most preferable that the resin is 1.4 or less, for example, a silicone resin. The amount of the low refractive index resin attached is preferably 0.1 to 1.0% by weight, more preferably 0.35 to 0.65% by weight, based on the weight of the fiber. By covering the colored fiber surface layer with the low refractive resin, the bathochromic property can be further enhanced.

This hydrophilic resin may be the same as the above low-refractive index resin, but may also have a slightly higher refractive index because it contains a hydrophilic group. For example, it is preferable to use a silicon-based resin as the low refractive index resin with emphasis on bathochromism and a urethane-based resin as the hydrophilic resin.

The thickness is preferably 50 μm, more preferably 5 to 20 μm. Since the particles are fine particles as described above, diffuse reflection of light is more complicated, so that the bathochromic property is improved, and since the particles do not easily fall off, the durability is improved. The amount of the fine ceramic particles attached is preferably 0.05 to 0.25% by weight, more preferably 0.1 to 0.15% by weight, based on the weight of the fiber.
