In the process of producing synthetic fibers, especially filament spinning, before polymer access to spinnerets, all the foreign substance has to be filtered. Meanwhile the polymer should be not leaked out of spin pack containers. Futai can offer you a complete set of element used inside spin pack body.

In many applications these filter elements: candle filters and discs filters are used in order to remove these tiny foreign substance, which advantage is: large filtration area to extend changing period, recycled many times after cleaning with long lifetime, especially for candle filter filament spinning.
