Abstract:

The basic properties of the high-frequency welding of garment pieces are presented. The impact of artificial leather properties on the quality and strength of high-frequency welding was explored. The weld quality and strength of different artificial leather samples were optimised by regulating the temperature, power and duration of welding. Based on the results obtained, it may be claimed that parameter changes in the welding process, as well as changes in the technological process of manufacturing artificial leather, in the raw material composition, coating component portions and colour of the polyurethane coat (PU) directly affect the quality, strength and water impermeability of the seam.
