All polyester fiber networks in defeng, Hebei province will undergo two stereotypes, so describe our thermal shaping process.

  1.We work at a constant temperature of 30 +-1 degrees Celsius and a temperature of 50-60 %

We strictly control room temperature according to the process requirements. The temperature of each circle of the fiber network is set according to technical regulations. The limit temperature can not exceed 170 degrees Celsius.

  2. Strictly control the uniform consistency of the oven and outlet temperature to prevent the uneven surface caused by uneven temperature and transverse contraction exceeding the limit during the heat reduction process.

  3. From the starting temperature, we must strictly follow the process requirements. Every turn of the fiber network must be measured at the same time as the latitude and longitude density and permeability, and the elongation, shrinkage, and tension of the mesh are calculated.

  4. Strict technical requirements to control the speed of the net, there will never be uneven speed, in order to avoid the various parts of the net heat uneven and can not be used.

Hebei Defeng always to achieve customer satisfaction as the first, to provide first-class products and services for customers.
