(2) In particular, even in the case of a light color or a medium color, the dough temperature is more likely to rise when it is exposed to a light ray containing near infrared rays, as compared with the case where a normal dye is used in a black or dark color. (3) Since a dye having an affinity for the fiber is used,
No binder is used. Therefore, the water absorption and hygroscopicity inherently possessed by the cellulosic fibers are not impaired at all. Furthermore, since the near-infrared absorbing agent is a dye having an affinity for fibers, the effect is hardly reduced by washing or dry cleaning. (4) This is suitable for winter clothing, for example,
When used in sweaters and trainers worn outdoors, the fabric temperature rises quickly when exposed to sunlight and is warm.
