METHOD FOR DETERMINING DIE CONTENTS IN TEXTILE MATERIAL Russian patent published in 1995 - IPC

FIELD: textile fabric processing. SUBSTANCE: method involves determining absorption band of electromagnetic radiation, measuring absorption band parameters, after electromagnetic radiation interaction with material took place. The material makes contact with the working surface of a member with the multiple violation of total internal reflection. Absorbed wavelength is set to be equal to the absorption wavelength of the solvent, parameters of the above mentioned member are selected by using a mathematical relationship. EFFECT: enhanced effectiveness of textile material quality control.
