Abstract

The invention discloses a preparation method of a flame-resistant washable filter material and belongs to the technical field of filter materials. The filter material is formed by mixing a polypropylene staple fiber, a three-dimensional crimped polyester staple fiber and a low-melting-point fiber, wherein the fineness and the length of the polypropylene staple fiber are 3-25 dtex and 40-90 mm respectively; the fineness and the length of the three-dimensional crimped polyester staple fiber are 6-20 dtex and 30-55 mm respectively; the fineness and the length of the low-melting-point fiber are 10-30 dtex and 55-90 mm respectively; such fibers are mixed by means of opening, carding, lapping and needle punching. The filter material is good in filter effect, washable, long in service life, wide in application range, environmentally friendly, free of pollution, and low in production cost.

Description

Technical field: [0001] The invention relates to the technical field of filter materials, in particular to a preparation method of a flame-retardant and washable filter material. Background technique: [0002] The atmosphere is one of the essential environmental elements for the survival and development of human beings. However, the increase in population, frequent human activities, and natural factors have caused serious air pollution. Protecting the atmospheric environment is our urgent duty. The environment in which human beings depend for survival consists of the natural environment and the social environment. The natural environment is the sum of natural conditions and natural resources necessary for human life and production, that is, the sum of natural factors such as sunlight, temperature, climate, geomagnetism, air, water, rocks, soil, animals and plants, microorganisms, and the stability of the earth's crust. The social environment is an artificial environment gr...
