The purpose of this study was to develop the color matching program with the excellent camouflage capacity in the near infrared range($~$1100nm) including the visible light range for cotton fabrics. It was measured IR spectral reflectance in the range of $380~1,100nm$ after dyed with vat dyes, and we made database for reflectance with various concentration on vat dyes which have a low reflectance value in the infrared range. The color matching algorithm that could be simulated in both the human visible light and the near infrared range was constructed by numerical analysis method using the database. In this study we also developed the dyeing conditions and dyeing process through the continuous-dyeing experiment with the vat dyes for cotton fabrics.
