Running polyester dust bag is made of high-frequency, high-density and high-speed production line of Sinopec Yizheng high-quality polyester fiber and polyester fine-woven fabric. All technical indexes are in line with GB/T6719-2009 standard. The product has high porosity and density. Good, high filtration precision, good ventilation and easy to clean. The vitrification temperature of polyester fiber is about 80 °C, the melting point is 255°C-265°C, the burning temperature is 450°C, and the softening starts at 230°C-240°C. It is a heat-shrinkable fiber. The strength loss caused by heating at 170°C for a short time can be Recovery, so polyester fiber has good performance at room temperature. It can work continuously for a long time below 120 °C.

Polyester is not resistant to strong alkali, poor hydrolysis resistance, water vapor of 5% or more, can be hydrolyzed at 100 °C, especially at higher temperatures; weak acid resistance, stable to general mailing solvents. Jiehua Company can waterproof and oil-proof, anti-static, PTFE acid and alkali treatment and flame retardant treatment of polyester needle felt, and it can cope with special working conditions to ensure long-term durability
