This thesis investigates the effect of raising the temperature during the process of machine drying of laundry on the degradation and creasing of textiles. By raising the drying temperature, the time needed to dry laundry is shortened. However, this leads to unwanted results, such as a higher emission of textile fibres into the atmosphere due to the faster degradation and greater creasing of laundry. The experiments were carried out on a standard heat pump dryer with a maximum load of 8 kg of dry laundry, which was modified by adding an electric heater to the process air circuit. The graphs in the results section of this thesis show the changes in temperature in relation to the drying time. The thesis also shows the amount of textile fibres caught on the dryer's filter, which proves that raising the temperature of the drying air leads to greater degradation of textile. The last part of this thesis confirms the hypothesis on the effect of temperature on the creasing of laundry. By drying the laundry at a higher temperature, the textile creased 3 times more than when dried at a lower temperature.
