Combine two different denier fiber to form a gradient filter, improve the filtering effect .this

type of felt can partly replace memberanecomposite felt to achieve fine filter.In addition,

these felt can be entitled with antistatic, oil and water repellent properties by special

chemical treatment to meet particular demand.

Application range: it is mainly used in the occation with higher filter requirement.
