Industrial filter cloth weaving method
Plain weave (a): plain weave filter cloth weaving method is to make each alternate alternately floating in each warp above each warp, and then sink in another under the warp, woven into the fabric in the absence of geometric deformation, the net hole
Was positive: square or rectangular, the size of the hole by the diameter of the wire or the unit length of the wire within the limit.
Twill (b): twill weave cloth weave method is that each weft alternately floats on two warp threads, and then sink in the two warp threads, the geometric deformation of the filter cloth. When the longitude and longitude of the filter cloth are long and multifilaments, the mesh is irregular.
Satin (c): The satin weave fabric is weaved in such a way that one weft thread (or warp thread) floats over several warp threads (or weft threads) and then sinks below one warp thread (or weft thread) process alternately.
Filtering performance
Filtrate transparency: Plain weave cloth> Twill weave cloth> Satin weave cloth> Nonwoven weave cloth
Filtration rate: Plain filter cloth <Twill filter cloth <Satin filter cloth <Non woven filter cloth
Filter cake moisture content: Plain filter cloth> Twill filter cloth> Satin filter cloth> Non-woven filter cloth
Unloading cake performance: non-woven filter cloth <plain filter cloth <twill filter cloth <satin filter cloth
Filter cloth life: non-woven filter cloth <Satin filter cloth <Plain filter cloth <Twill cloth
Regeneration performance: Satin filter cloth> Twill filter cloth> Plain filter cloth> Non-woven filter cloth

The use of filter cloth
Polyester, polypropylene, vinylon identified by the relevant health authorities for food, pharmaceutical and other industries on human health without side effects. The company is located in:
2. Food, pharmaceutical industry before using warm water rinse, so as to avoid cloth dirt into. The company is located in:
3. Cutting, electric iron ironing the best (with 1500W electric iron), to prevent the latitude and longitude lines loose. Sewing thread must use the same line of performance. The company is located in:
4. After the filter cloth is used, if the cloth is clogged by the dregs to make the cloth body stiff and affect the filtration speed, the solution can be selected according to various fiber properties such as acetone, oxalic acid, toluene, caustic soda and alcohol, soaking,
(Concentration, as the case may be) to make the body soft, restore the hydrophobicity and permeability of the filter cloth, improve the filter cloth usage. The company is located in:
5 can produce special specifications of the product. Such as fabric width can be increased or decreased, the diameter of the bag can be arbitrarily selected, but the first half to one month notice, so that the product can be planned
