Under wet-heat treatment (WTO or VTR) garments understand special processing of a part moisture, heat and pressure using special equipment.

WET-HEAT WORK: the nature, objectives, parameters, methods
The objectives of the WTO:

  • giving smoothness;
  • the thinning of joints between the edges;
  • the linear dimensions of the individual sections of the parts;
  • giving a forced shrinkage of the tissue;
  • stabilization of the shape of parts and products;
  • the formation of the product appearance and;Sedalia;
  • the removal of Las.

The essence of the process of wet-heat treatment is shown in its stages:

  • the softening of the fibers with moisture and heat (by heat transfer processes — forced convection, conduction and thermal radiation);
  • in giving the fabric a specific shape forming (the forming process);
  • in the retention shape by removing moisture with heat and pressure (stabilization of form).
  • The parameters of the WTO — temperature, exposure time, pressure and the degree of hydration. WET-HEAT WORK: the nature, objectives, parameters, methods

    There are 3 ways of implementation of the WTO:

  • Ironing — the work surface of the equipment moves along the surface of the fabric.
  • Pressing the working surface of the equipment is not moved on the surface of the fabric, but puts pressure on the fabric.
  • Steam — the working surface of the equipment may specify the shape of a part, but the pressure has not. The effect of the WTO is achieved only by the successive steaming and drying of the product/parts.
