Standardized textiles and mixed consumeritems (3 kg and 5 kg loads) were dried in a modified dryer with an external high-efficiency filtration system that enabled time-resolved gravimetric measurement ofreleased fibers. Shedding was driven by mechanical stresses from textile motion andinteractions, which depended strongly on drum speed and load characteristics. Thegreatest fiber release occurred at the nominal 58 rpm, associated with the cataractingregime. Lower speeds (10–30 rpm) reduced shedding but increased drying time, whilea higher speed (70 rpm) combined with frequent textile redistribution produced thelowest shedding with little effect on drying duration. Load mass effects differed by loadtype: standardized 5 kg loads shed more than 3 kg loads, whereas the mixed consumerloads showed an opposite trend, which is interpreted as a load-composition effect ratherthan a direct mass effect. Overall, the results show a complex coupling between drumdynamics and textile interactions and indicate that adaptive drying strategies can reducefiber release during tumble drying without compromising drying performance.20262026-05-07 11:58:42Članek v reviji182331sl
