Title: METHOD AND APPARATUS FOR STAIN TREATMENT
Abstract:
A method for identifying a stain on a textile (10), the method comprising the steps of: performing near-infrared reflectance spectroscopy to obtain spectral data from the stain over a range of wavelengths ranging from a shortest wavelength to a longest wavelength, the shortest wavelength having a value of 1595nm or longer; accessing reference spectral data (33) of known stains; and comparing the spectral data of the stain to the reference spectral data of known stains to identify the stain.
