[Research for the test method of polypropylene fiber liquid filtration membrane particles shedding].

Through five experiments, such as "Circle", "square", "side that does not shake", "burning edge", "filter", this paper discussed the effect of different experimental methods of polypropylene fiber liquid filtration membrane particles shedding. The results show that: the particles falling off the edge of the polypropylene fiber Double-sided liquid filtration membrane are very important and must be considered off the evaluation of particle pollution.
