Water repellent and oil proof needle punched felt bag

  The filter bag made of water and oil repellent needle punched felt bag filter cloth after water and oil repellent treatment is used in occasions with large moisture content
Compared with ordinary filter bags, because the filter material is not easy to block the paste bag and prolong the ash cleaning cycle and the service life of the filter bag, our company is committed to the development of finishing technology and is equipped with the most advanced filter material finishing equipment in China
The products are processed by processes such as singeing, calendering, dipping, coating, drying and shaping, The post-treatment level is in a leading position in China

The production process of water repellent and oil proof needle punched felt bag is as follows:
Fiber loosening - Carding - mesh laying - pre pricking - Main pricking - felting - singeing - calendering - impregnation - PTFE (waterproof agent) drying - setting - rolling - coiling
