Abstract

The invention discloses a hydrophilic and oleophobic filter material and a preparation method thereof. By effective technology, produced filaments are subjected to chemical modification and are added with plant composition, and thus, treating performance thereof is changed. Compared with common fiber balls, the hydrophilic and oleophobic filter material has the advantages that the modified fiber balls have small wire diameter and large specific surface area which is up to 2500m2 / g. Owing to the characteristic of small wire diameter of the filaments, pores of filter layers after superposition of the filaments are small and the porosity of the filter layers after superposition is over 85%, and accordingly the filter material is superior to other filter materials in terms of interception of suspended matter.

Description

technical field [0001] The invention belongs to the technical field of filter materials, and in particular relates to a hydrophilic and oleophobic filter material and a processing method thereof. Background technique [0002] Plant fibers are formed by the development of different meristems. The fibers of xylem and phloem originate from the procambium or cambium. Some fibers can be generated by the basic meristem, the cells that will develop into fibers in the future, stop dividing horizontally very early, and only elongate longitudinally. Part of the fibers in the vascular bundle sheath can be generated from the procambium, and the other part can be formed from the basic meristem. [0003] Cotton fibers are elongated portions of epidermal cells on cotton ovules. Its development process is: when the cotton ovule is fertilized, the hair cells that produce fibers on the epidermis of the ovule elongate rapidly. Since then, the cell wall has gradually thickened, that is, the...
