Methodology for determining selected characteristics of polyethylene dyeing using CIELabs ystem

Polimery 2019, No 10, 690


DOI: dx.doi.org/10.14314/polimery.2019.10.6

Summary

The paper presents the original method for the preparation of polyethylene samples used to assess the color change in the CIELab scale, by using a mixture of selected dyes. In order to verify and evaluate the color variability of a series of PE samples with four pigments (magenta, blue, green, yellow), the Cary 5000 spectrophotometer was used for recording reflectance spectra of individual samples demonstrating the effect of mutual mixing of the dyeing concentrates used in the study.


Keywords: color measurements, coloring of polymers, mixing and dosage of polymers, methodology of samples preparation
