Sažetak
Coated textiles are mostly used in clothing, medicine and transport. Advantages of polyurethane coatings are greater resistance to abrasion and splitting, increased s trength and durability. The properties of such materials can be significantly affected by pigment dispersion. Polyurethane- coated knitted fabrics were of interest because they exhibit positive mechanical and thermal properties, and yet they are little studied. Polyurethane coating was prepared in pastes in yellow, blue and dark blue hue, which is used to obtain polyurethane coatings. The results are presented as differences in CIEL*a*b* colour parameters and total colour difference. After exposure to the natural weathering, it is noticed that in the summer season the materials in dark blue hues resist best, while in winter conditions the smallest difference in colour is obtained for yellow materials. In addition, a good correlation of knitted substrate mass, thickness and yarn count with colour fading occurred.
