When the fabric reaches a certain temperature and remains for a certain period of time, the structure of the fabric changes to achieve the purpose of setting.
The double-point lining coater is the main equipment for processing high-grade low-elastic linings and thin non-woven linings. It mainly consists of several parts such as retort, slurry coating, dust coating, up and down suction, drying room, cooling and winding, pneumatic and electrical control.
The Hot Air Stenter mainly consists of a feeding device, a preheating zone, a high-temperature setting zone, a cooling zone and a cloth discharging device. The feeding device is to make the fabric perpendicular to each other under a certain tension or a certain relaxed state including a tension frame, a weft detector, a suction device, an over-feed device, an automatic control device, edge-detector and so on, which can make it smoothly enter the machine. Then, the fabric is heated to a certain temperature through the top hot zone to avoid the cold forming fabric directly entering the high-temperature setting zone and affecting the setting temperature.
The preheated fabric enters the high-temperature setting zone (with steam heating and electric heating device) so that the fabric is evenly heated for a certain time, after reaching the molding requirements, then enter the cooling zone to cool rapidly, and finally, the fabric is passed through the cloth roller and the cloth dropping frame.
The operation of the fabric in the machine is driven by a clip chain or pin-plate or clip chain. A static eliminator should be installed at the fabric outlet, or a steam vent and a metal screen should be installed in front of the fabric roller to spray a proper amount of steam on the cloth surface to appropriately increase the moisture regain of the fabric in order to reduce the generation of static electricity.
