At the same time, it should be comfortable to wear and provide good protection against heat and open flames.
  • Natural fibers such as cotton offer good wearing comfort due to the high moisture absorption and skin friendliness, but cotton yarns suffer during washing and drying, especially under industrial conditions, since industrial washing machines and dryers work with higher loads, higher detergent concentrations and higher temperatures than household appliances. This stress leads to the fluffing of the cotton fibers: the cotton thread breaks open little by little and becomes thinner, the cotton "washes out” and the yarn loses its strength.
