Due to the negative thermal conductivity of the fabric, moisture has a significant impact on the 

quality of wet-heat treatment. 

Studies  have  shown  that  when  processed  through  a  damp  cloth,  a  4-layer  suit  fabric  can  be 

heated to 130 C at temperatures up to 1000C. 

Then the fabric goes to the drying stage. When using a damp cloth, the temperature can be raised 

to 110-1200 C to stop ironing. 

The  wet-heat  treatment  process  in  steam  presses  allows  to  achieve  almost  stable  steam 

parameters, as well as to accelerate the processing process by increasing the steam pressure. 

Wet-heat  treatment  of the product  is  carried out  on electric and steam  presses, air mannequins, 

irons. 

The  control  of  the  wet-heat  treatment  mode  is  carried  out  by  means  of  devices  that  allow  to 

measure the following parameters: 

a) The surface temperature of the working bodies

b) Surface temperature of the working medium; 

c) The density of heat flux transferred from the working body to the workpiece

g) The pressure exerted by the working bodies on the product; 

d) Duration of processing

e) temperature, humidity and pressure of the working medium at different internal points of the 

fabric. 


Various thermometers, thermometers, resistance thermometers are used to measure temperature. 

The  maintenance  of  the  parameter  mode  is  performed  on  the  following  special  control  and 

measuring devices: 

1) temperature regulators; 

2) devices for determining the duration of processing (steaming, drying, cooling); 

3) electric and pneumatic steam and vacuum devices for spraying the product with water, as well 

as for humidification with steam

4) electric, pneumatic and hydraulic cylinders providing the required pressure. 

The  working  area  of  the  working  surface  of  the  iron  and  press  pads  is  determined  using  a 

portable meter IT-3, IT-5. 

Wet-heat treatment operations are divided into 4 main stages:
