[0002] A common heat setting equipment for polyester knitted fabrics is a hot air dryer. It is a device that heats the polyester knitted fabric by heating the air. The working principle of the hot air dryer is to heat the hot air to a certain temperature through a heating element (usually an electric heater or a gas burner), and then send the hot air to the drying chamber where the fabric is located through a fan. The polyester knitted fabric will be heated by the hot air and obtain the desired shape and dimensional stability in the chamber. Hot air dryers are often used in the finishing stage of the weaving process to remove moisture from polyester knitted fabrics and perform heat setting on them. Different heat setting effects can be achieved by controlling parameters such as the temperature, humidity and wind speed of the hot air.
