DESIGN OF COLORIMETER USED IN THE GARMENT INDUSTRY

Abstract

Color evaluation criteria play an important role in the production and improvement of the quality of textile products. Determining the color fastness of the fabric from the approved fabric color before production, the color fastness of the fabric before and after washing, the color evenness between the details in the product is necessary. To perform the above work requires precise measuring instruments, which are expensive and often beyond the investment capacity of small and medium-sized textile enterprises. This study is based on the color theory of CIE used to measure the color of fabrics commonly used in quality control, thereby designing and manufacturing an objective colorimetric instrument. The instrument has a simple structure, uses an RGB color sensor and a microcontroller with embedded software. Experimental results of testing the color measurement data of the instrument and of the reflectance spectrometer in the laboratory on fabric samples available on the market show that the instrument works relatively reliably, the accuracy can be acceptable for routine applications in garment manufacturing. The instrument can be used in practical experiments on fabric colors and clothing in training and teaching textile materials for university students.
