Knitted fabrics are processed by a continuous heat setting machines, which on the one hand effectively improves the quality of the product, on the other hand reduces the damage to the fabric, and has good flexibility and reproducibility, while reducing part of the production cost. The so-called tenter setting machine is mainly a machine for shaping a fabric.
Usually in the use of the heat setting machines, the air inside the machine is heated mainly by means of the heat-conducting oil, and then the fabric is heated. When the fabric reaches a certain temperature and remains for a certain time, the structure of the fabric changes to achieve the purpose of shaping. With the development of technology, its overall trend is: to the development of environmental protection, energy saving, saving time, high efficiency, short process, focusing on new technologies such as waterless processing technology, non-plate printing technology, low temperature plasma treatment.
Another important development trend is that automation technology will be widely used. In the control system, programmable logic controller (PLC) or industrial computer control (IPC) is applied. The parameter online monitoring is universally applied, which improves the automation of the stenter. The process stability and reproducibility are greatly improved.
