stability of synthetic fiber polyester filter cloth

Thermal stability of synthetic fiber polyester filter cloth in several main is the best. polyester filter cloth was heated at 150 ¡æ for 168h, the strength loss of not more than 3%, and the nylon at 150 ¡æ heated 5h yellow, fiber strength decreased. Most of the carbon chain fibers in the above 80-90 ¡æ heating deformation will occur, the loss of strength is very difficult to restore. So for polyester / cotton blended fabric was the thermal processing, should focus on the consideration of heat resistance of cotton fiber itself.
The temperature range of polyester filter cloth can allow larger, can be used in -70-170 ¡æ, low fiber not brittle. If the pet in the production of cloth with good heat, so heat shrink its youngest.
