Problems solved by technology

In the prior art, the patent document CN200710038014.2 only requires the diameter of the thick fiber to be 100 to 1000 microns, without considering the cross-sectional shape of the thick fiber, and the diameter of the thick fiber is difficult to reach 100 microns, which causes fiber loops The elasticity is not high, causing the fiber filter to be blocked after a short service life
When filtering chlorine-containing substances, table salt, tap water, bleaching powder, disinfectant, pesticide, paint, etc. will cause fiber oxidation, and ultraviolet radiation will cause fiber aging, resulting in shortened service life of fiber filter

Abstract

The invention discloses a polypropylene fiber bulked filament for an environment-friendly fiber bundle filter and a preparation method of the polypropylene fiber bulked filament, and belongs to the technical field of chemical fiber materials. The cross section of a monofilament is a trilobal special-shaped bulked filament, polypropylene slices, chlorine-resistant master batches and anti-UV master batches are mixed for spinning, the linear density of a single filament is 40-45 dtex, the density of a multifilament is 3000-3600 dtex, and the diameter of the fiber is 100 microns or above. The anti-chlorine master batch is prepared by mixing, melting and pelletizing a chlorine-resistant antioxidant double-effect agent and polypropylene powder according to a ratio of 1: 1, and the anti-UV master batch is prepared by mixing, melting and pelletizing 15.0-17.0% of an anti-aging agent, 15.0-17.0% of UV powder and 66.0-70.0% of polypropylene powder. The polypropylene fiber bulked filament has the advantages of large diameter, high fluffiness, good springback, low cost, large specific surface area, and low filtering resistance, the filtering efficiency and the pollutant intercepting capacity are improved, the chlorine oxidation resistance and the UV aging resistance are improved, and the service life of the filter is prolonged.
