The weaving method of industrial filter cloth
Plain weave (a): plain weave fabric weaving method is to make each weft alternately floating on each warp and then sink to the other under the warp, woven fabric in the absence of geometric deformation of the case, the net hole
The size of the hole is defined by the diameter of the line or the number of wires in the unit length.
Twill (b): Twill weave The weaving method is that each weft is alternately floating over two warp lines, and then sinks under two warp lines, and the geometric deformability of the filter cloth is large. When the filter cloth warp and weft with long filament, the mesh is irregular.
Satin (c): The weaving method of the satin weave is a weft (or warp) floating on a number of warp (or weft) and then under a warp (or weft) process alternately.

Filter cloth instructions
1. Polyester, polypropylene, vinylon by the relevant health sector identification, for food, pharmaceutical and other industries have no side effects on human health.
2. Food, pharmaceutical industry before the application of warm water rinse, so as not to bring the dirt into the cloth.
3. Cutting, the use of iron iron ironing for the best (with 1500W electric iron), to prevent loose latitude and longitude line. The sewing thread must use the same line of performance.
4. After the use of filter cloth, if the clogs blocked cloth holes, so that the cloth body hair hard affect the filtration rate, according to a variety of fiber properties using acetone, oxalic acid, toluene, caustic soda, alcohol and other solutions, soaking,
(Depending on the concentration may be) to soften the cloth body to restore the hydrophobic and breathability of the filter cloth to improve the filter cloth usage.
5. Can produce special specifications of the product. If the width of the cloth can be increased or decreased, the size of the bag can be arbitrarily selected, but please inform the first half to 1 month, so that the product can be planned
