Perfect resistant against washing. 1% or less shrinkage at 100°C, 2% or less shrinkage at 150°C.


After 150°C, physical and chemical changes occur.


The ideal conditions are; fluorescence or tungsten light, 15-25° C temperature and 40-60% moisture.

Dyeing Technology and Lubrication

A lubrication process is applied, that shows optimum stitch performance in high speed stitches and displays a proper stitch, that does not generate a tone difference over the colors and that does not change during storage. Due to the dyeing methods, those are applied diligence, the color fastness and no shrink at temperature is provided. Our swatch card is presented with 300 standard colors.
