I produced a dust bag and cheap, exported abroad, get the praise of customers, some customers to plan without planning your classification is not very clear, today I sum up, dust bag of classification a variety of ways, and we look together. First, the processing method according to the processing method is mainly divided into woven filter dust bag, non-woven filter dust bag and composite filter dust bag three. 1, a woven filter dust bag: the mutually vertically aligned with loom warp and weft yarns, according to a certain organization of the woven filter, indicated with the letter W; 2, non-woven filter sets Dust bag: without general spinning and weaving process, directly into a network of fibers or yarns into layers, interleave, filter sheet bonding, needling, melt blown or spun made, and the letters NW composite processing methods specific letter code representing the composition; 3, the composite filter dust bag: made of two or more methods or more composite materials made of dust bag filter, with the letter C. Second, the weave of the fabric tissue filter dust bag is divided into plain, twill pattern filter media and forging three. 1, plain weave: This is the simplest form of weaving, each warp yarn and each weft alternately, but there is a plain weave difficult cleaning and easy to plug other shortcomings, therefore, this organization has been rarely used for weaving dust filter ; 2, twill weave: from two roots, the next four warp and weft interwoven same time, warp and weft interwoven point gradually move left or right; twill weave twill-sided and double-sided twill points; twill weaving flexibility and elasticity are better than plain cloth, slightly lower mechanical strength, easily misplaced by the force, but its wear resistance, dust removal efficiency and cleaning effect is also good, is woven filter most common kind of organization; 3, forging weave: can be seen on the surface of the fabric according to the warp or weft into warp and weft pattern surface forging forging surface pattern; forging weave is characterized by a smooth, shiny surface, very soft, good elasticity and breathability , and because the yarns have mobility and easy cleaning. Third, cross-sectional shape of the bag by bag is divided into sub-circular cross-sectional shape, flat and profiled three. 1. Round: dust bag is cylindrical. Specifications i.e. D × L (mm) Diameter × length represented by; 2, flat: Filter bags for a flat shape, including rectangular and trapezoidal, its specifications i.e. P × L (mm) × length represented by perimeter; 3 profiled: bag shape specific characteristic parameters representing its specifications for its construction. Fourth, the filtering by filtration is divided into an outer filter within the filter type two. An inner filter bag type dust: dust and gas after the inner surface of the filter bag, dust is blocked on the inner surface of the bag, which is called filtering within the filter type; 2, outside the filter dust collector bag: After the outer surface of the dusty gas bag filters, dust is blocking the outer surface of the bag, which is called the outer filter type filtering more theatrical, please contact: 18034170380
