Abstract

The invention relates to a preparation method of a lampblack air filtering material. The raw material is a self-twisted fiber. The technological process comprises the following steps of opening, blending and cotton feeding, carding, laying and web forming, flame-retardant adhesive preparation, flame-retardant adhesive spraying, drying and reinforcing, ironing and trimming and lapping. The preparation process of the self-twisted fiber comprises the following steps of distributing a PET melt and a PTT melt according to a staple spinning process, and extruding from a spinneret orifice in the samespinneret plate to obtain a staple fiber, namely the self-twisted fiber, wherein the staple spinning process comprises a relaxation heat setting procedure, and the temperature is 100-110 DEG C; the cross section of the spinneret orifice is (formula)-shaped and is formed by a transverse line, a vertical line vertically connected to the transverse line and a diagonal line obliquely connected to thetransverse line; and the distribution refers to controlling the PET melt to flow through the transverse line while controlling the PTT melt to flow through the vertical line and the diagonal line. According to the preparation method, a simple preparation method is adopted to prepare the fiber with the twisted structure, so that the lampblack air filter material with high filtration efficiency isprepared.

Description

technical field [0001] The invention belongs to the field of fiber technology, and relates to a preparation method of oil fume air filter material. Background technique [0002] With the rapid development of the catering industry, techniques such as frying, frying, frying, and grilling are used in the food processing process, resulting in a large amount of soot and exhaust gas. These soot exhaust gases include gas, liquid, and solid three-phase pollutants, whose chemical composition is extremely complex, and has strong carcinogenic and mutagenic effects. These soot pollutants are discharged outdoors without any treatment, which not only pollutes the living environment of the surrounding residents, but also destroys the air quality and seriously endangers human health. [0003] For oil fume purification, the oil fume purification treatment methods currently on the market mainly include mechanical separation method, catalyst combustion method, adsorption method, electrostatic...
