The filter belt production abroad and research importance, many commonly used filter belt series has been formed. In 1988, the industry statistics of the filter belt textile market scale: the United States accounted for 31%; Japan accounted for 33%. The filter belt from foreign material, manufacturing process, strength and wear resistance, porosity and filtering precision, application scope, installation method, the regenerative way and so on have a detailed research, such as: Swiss Seidengazefabrik, ZBF; German Hein Lehmann; Belgian BSS (Bekaert Separation Systens); Japan's Nagaoka kanani; The famous Eimco company etc, the filter belt sample can usually list that the density, thickness, tensile strength, porosity, permeability is screen mesh, average aperture, resistant temperature, water and acid, alkali, oxidation of performance information. The user can according to manufacturer offers information, choose intensity, abrasion resistance, corrosion resistance, long life supporting the use of the filter belt, in order to improve equipment processing power and separation quality, to achieve the ideal of separation result.

Some of the performance of the filter belt mainly depends on the performance of the fiber, abroad in recent years in this work is mainly in material on a high-quality fiber materials, namely choose mechanical properties, filter performance better fiber for filter belt; In the production technology by several finishing technologies, such as research light, fleece and heat treatment, or change the filter belt surface smooth degree, improve the ability of the filter cake of unloading; The filter belt or improved to fine a pull of stable; Or stable fiber, make is suitable for the high temperature, etc.

In the foreign filter belt fiber materials for a large amount of research, such as high strength, heat resistance, high shrinkage, composite, flame retardant, antistatic, uv etc special fiber research. Use superfine fiber production quality of efficient filter belt, it can satisfy different industry precision filtration of performance requirements.

Foreign to filter belt performance testing methods did a lot of research. Because both of the filter belt factory or salesman must be on the performance of the filter belt quantitative description, so as to facilitate the evaluation and selection of filter belt. So in the 60 s, many scholars abroad to filter belt performance measurement method of the research, the international community make some corresponding determination of the filter belt performance methods and standards.

Performance of the filter belt were usually include the project of the filter belt aperture, clean the resistance of the filter belt or penetration, the filtering process the resistance of the filter belt, intercept efficiency, filtering precision, tolerance of the filter belt slag discharge capacity and bread performance, etc. At present, foreign health cloth performance for the test standards mainly has: the side of the filter belt aperture decided, clean the determination of the filter belt permeability, including air rate and permeable rate; The side of the filter cloth interception performance set.
