Abstract

The invention discloses a filtering material and a preparation method thereof. The preparation method comprises the following steps of: placing a double-component island fiber into emulsion formed by mixing o-chlorophenol, a surfactant and water; treating under an oscillation condition; washing by pure water; and after carrying out tentering, drying and hot-rolling treatment to obtain the filtering material. An emulsion treating technology is used for completely splitting the island fiber and the specific surface area is enlarged; and an obtained superfine fiber textile has excellent adsorption and separation function, and filtering effect. Compared with a melt-blown non-woven fabric, the island double-component fiber has the advantages of multiple varieties of fibers, large output, developed production process, great brute force and the like; and the filtering material can be applied to an ultra-cleaning filtering and cleaning field and has a popularization and application prospect.

Description

technical field

[0001] The invention relates to a filter material and a preparation method thereof, in particular to a technology for applying ultrafine fibers obtained by splitting two-component sea-island fibers to air filter materials, and belongs to the technical field of polymer materials. Background technique

[0002] The island-in-the-sea composite fiber spinning technology researched and developed by Japan in the early 1970s has matured and become the basic process for producing ultrafine fibers after decades of development. Microfiber is a fiber with a diameter of about 0.1 denier. Microfiber has a large specific surface area, and its fabric has good bulkiness and warmth retention. Fibers with large specific surface area and large surface energy have a high probability of contact with dust or oil, and can capture and fix fine dust like a magnet, so it has a strong cleaning function. Microfiber fabrics (including woven fabrics and non-woven fabrics) have super ...
