Owning puff yarn and covering capacity, this cloth has good function in filing.  Including continually fiberglass filter cloth’s advantage, it also has its own characters such as: low blocking, high efficiency. Under the same station, it has 3/4 blocking than continually one. And it can discharge to 24mg/Nm2 when in stove end.

Referencing to the American Teflon formula , we success in TFB bulked yarn filter cloth with good chemical material and special accessory.  Function and index is as follows:

According to the above data, we can get the idea: TFB folding fiber glass bulked yarn filter cloth has the equal capacity with U.S fiber glass bulked yarn filter cloth. And also it improves it ability of folding and water resistant. Which prolong its life. So we use TFB instead of U.S one. Now it has been widely used in  cement, carbon black, iron for treating smog and recovering industry products.
