一般情况下，当工业粉尘浓度出现一定程度（即爆炸极限），如果静电放电火花或外界点火存在，爆炸和火灾可能发生容易。 这样的粉尘作为粉尘，化工粉尘，煤尘等都有爆炸的可能性，如果满足静电放电。 在袋型除尘日提交，如果这些粉尘需要由布袋收集，它要求该制成袋布本身具有抗静电功能。 为了生产防静电滤波器原材料的需求，融入在基布经导电纤维或具有生产普通针刺毡的过程中混入导电纤维，化纤，分开。

Generally, when industrial dust concentration comes up to certain extent (i.e. explosion limit) , if static discharge spark or outside ignition exists, explosion and fire disaster may take place easily. Such dusts as flour dust, chemical engineering dust and coal dust etc. all have the probability of explosion if meeting static discharge. In bag-type dust removal filed, if these dusts need to be collected by cloth bags, it is required that the made cloth bags themselves have antistatic function. To produce antistatic filer materials demands merging into electrically conductive fiber in base cloth warp or mixing into electrically conductive fiber in chemical fiber, apart from possessing the process of producing common needled felt.
