Title:
EFFICIENT LOW-RESISTANCE MICRO-NANO-FIBER MICROSCOPIC GRADIENT STRUCTURE FILTRATION MATERIAL, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/200641
Kind Code:
A1
Abstract:
Disclosed is an efficient low-resistance micro-nano-fiber microscopic gradient structure filtration material comprising a nano fine filtration layer (A), a micro supported primary filtration layer (B) and a protective surface layer (C), wherein the micro supported primary filtration layer (B) and the nano fine filtration layer (A) are superimposed and arranged between two protective surface layers (C), and the nano fine filtration layer (A) has a mesh structure composed of a planar base fiber layer (D) and a pyramid structure (E), wherein fibers between the tip of the pyramid structure (E) and the mesh base fiber layer (D) form a structure oriented along the tip and the planar base fiber layer (D). Disclosed is a method for preparing an efficient low-resistance micro-nano-fiber microscopic gradient structure filtration material.
