た。As is clear from Table 1, the fabrics obtained in Examples 1 to 3 satisfy the infrared reflectance in the wavelength range of 、 to 、. It was difficult to distinguish it from the object, and it was difficult to detect it even by reconnaissance with reconnaissance equipment using infrared rays, and it had camouflage performance. Further, the camouflage performance was excellent in various fastnesses of light resistance and friction, and had good durability. On the other hand, the fabric obtained in Comparative Example 1
Because it was not made of fibers containing an infrared absorber, it did not satisfy the infrared reflectance in the wavelength range of, and in forests and grasslands, it was difficult to distinguish it from the surroundings with the naked eye, but with infrared reconnaissance equipment It was easily detected during reconnaissance and did not have camouflage performance. Moreover, since the cloth obtained in Comparative Example 2 was obtained by coating the cloth with the infrared absorbent in the post-processing, the infrared absorbent and the resin were separated from the surface of the cloth by friction, and the friction fastness was poor. Furthermore, the periphery of the cloth was contaminated by the peeled infrared absorber or resin, and the practicality was poor.

きる。The fabric comprising the infrared-absorbing fiber of the present invention has a camouflage performance that makes it difficult for the naked eye to distinguish it from the surrounding environment and objects, and that is hardly detected by reconnaissance using a reconnaissance device using infrared rays. The camouflage performance of this fabric can be made excellent in durability.
