Abstract
Use of the customary dyes for the type of fibre in question and using the customary dyeing and/or printing processes for the type of fibre in question for minimally reducing, retaining or increasing the NIR reflectance, preferably increasing the NIR reflectance, in the region of electromagnetic radiation of wavelength 700 nm to 1100 nm of textile material in relation to the undyed and untreated textile material, characterized in that metal-free dyes are used.
Claims6
A method for minimally reducing, retaining or increasing the NIR reflectance, in the region of electromagnetic radiation of wavelength 700 nm to 1100 nm of a printed or dyed textile material in relation to the undyed and untreated textile material, comprising the step of dyeing or printing the textile material with a metal-free dye.
A method for increasing the NIR reflectance, in the region of electromagnetic radiation of wavelength 700 nm to 1100 nm of a printed or dyed textile material in relation to the undyed and untreated textile material, comprising the step of dyeing or printing the textile material with a metal-free dye.
