Pleating processing filter which has a single-layer single-component melt-spun media

摘要

Pleating processing filter has a Gurley stiffness of at least 100 mg, further orientation and fiber structure may be softened while retaining, were combined to form a cohesive and manageable Web, the same polymer composition a partially crystalline oriented fibers are partially amorphous, are prepared from monocomponent monolayer nonwoven web of continuous monocomponent melt spun. Column folds are formed in the nonwoven web, the web is cut to the desired size and shape, joined together at least some of the points of the fibers intersection, at least 15% at a face velocity of 1.52 m / s including a self-supporting porous single-component single layer matrix of fibers having an average initial sub-micron efficiency, to form a pleating processing filter element. Filter element, stiffening layers, bicomponent fibers, adhesive, or other reinforcement, a deformation resistance without the need for filter media layer.
