Analyzing the Dyeing Behavior and Chromaticity Characteristics of Polyester Microfibers
The dyeing properties of polyester microfibers and regular polyester filaments are studied by measuring the dyeing rates of four disperse dyes, the K/S values, and the color properties of cross-sectional views of the dyed fibers.

Zusammenfassung: | The dyeing properties of polyester microfibers and regular polyester filaments are studied by measuring the dyeing rates of four disperse dyes, the K/S values, and the color properties of cross-sectional views of the dyed fibers. The research reveals that at 70°C, dye exhaustion of microfibers is very small, meaning that dyeing the fibers at a low initial dyeing temperature is less effective in achieving good color effects, particularly with high energy disperse dyes. Also, when dyeing microfibers, small disperse dyes require a low dyeing temperature and bulky dyes require a higher dyeing temperature. Microfibers have a lower initial dye exhaustion temperature than regular fibers. Based on reflective curves, some chromaticity characteristics of the microfibers are also reported. |
