Filter material, referred to as filter material, refers to materials used for filtration and separation. Under the action of driving force or other external force, the liquid (or gas) in the suspension passes through the filter material, which can intercept solid particles and other substances and separate the solid and other substances from the liquid (or gas). This process is called “filter”. Filter material is a key component of filtration operations and can determine the separation accuracy and efficiency of filtration operations. According to different physical separation filter media, filter materials can be divided into filter mesh, filter element, filter paper, filter cloth, etc.

There are various production methods for filter materials, including spunbond, needle-punched, spunlace, melt-blown, wet nonwovens and electrospinning. The melt-blown method uses high-speed hot air flow to rapidly stretch and solidify the newly extruded polymer melt at high times to form a filter material composed of a fiber phase and a pore phase, which has the characteristics of low resistance, high efficiency, and low energy consumption. Advantage. In the context of “double carbon”, consumers’ requirements for environmental quality and environmentally friendly production are constantly increasing. Filter materials have developed rapidly due to their advantages such as relatively simple production processes, diverse production methods, and low production costs.

The raw materials of filter materials include glue, fruit shell, quartz sand, garnet, non-woven fabric, etc. As the main raw material for filter materials, non-woven fabrics have the advantages of being dry, breathable, stretch-resistant, flame-retardant, non-toxic, tasteless, moisture-proof, low-cost, and recyclable. They are new environmentally friendly materials. According to data from the National Bureau of Statistics, my country’s non-woven fabric output reached 5.386 million tons in 2021, a year-on-year increase of 6.7%. Adequate supply of raw materials will provide the foundation and guarantee for the development of the filter material industry. In addition, my country’s polytetrafluoroethylene filter material is a subdivided product of filter materials. Polytetrafluoroethylene is used as the raw material. It has the advantages of strong chemical stability, low filter wear, and corrosion resistance, and is favored by a wide range of consumers.

According to the “2022-2027 China Filtration Material Project Investment Feasibility Research Report released by the Industrial Research Center, filter materials can be applied Used in water filtration, vacuum cleaners, car filters, air filters and many other fields. At present, vacuum cleaners mainly have three filtration methods: dust bag filtration, dust cup filtration and water filtration. The finer the filter material in the vacuum cleaner, the cleaner the air can be filtered. According to data from the National Bureau of Statistics, the cumulative output of household vacuum cleaners in my country from January to November 2021 reached 130.899 million units, a year-on-year increase of 5.3%. Application demand will drive the growth of filter material production capacity.

Industry analysts said that filter materials, as a key component of filtration operations, have diverse production methods and low production costs, and the industry has entered a rapid development stage. Filtration materials have a wide range of raw materials. Non-woven fabrics, polytetrafluoroethylene and other materials have advantages such as corrosion resistance and flame retardancy, which provide guarantee for the development of the filter material industry. As the concept of environmental protection continues to deepen, the application fields of filter materials will become wider.
