Applying TCS3200 sensor to design colorimeter used in the textile industry

Abstract

Criteria for color evaluation has played important role in manufacturing and improving the apparel product. The determination of color variation, uniform color scale, colorfastness, etc. require precision measuring equipment and expensive and often beyond the capacity investment of small and medium-sized manufacturing enterprises as. To check the quality of products in the manufacture of garment industry as well as in the stage of the contractual delivery of raw materials, semi-finished products and the final product, the colors are usually based on the method of assessment experience, the owner should be risk-prone and conflict.

The contents of this study is to design and create a kind of measuring instrument is made simple and relatively reliable, accuracy can be acceptable in business and manufacturing field. Colorimeter is products according to the reflectance measurement with a 45˚/0˚ geometry, the color signal is collected by a color sensor TCS3200, which appears on the market of our country. Stimulus color values  R, G, B of the sensor is processed on SPSS software on the actual values  measured on the sample unit and converted to the CIELab color by multivariate regression.

Based on the inspection standard of whiteness, colorfastness of textile materials, evaluating results of instrument are fast and reliable. Colorimeter can be manufactured at low-cost so it is suitable for the production in the current textile business.
