Woven Filter Fabric

Woven filter material is mainly in the form of monofilament made of warp filter material spinning machine and cotton yarn. According to the material and monofilament form used in the weave filter, it can be divided into two parts: silk filter filter System of materialsMaterial at the time of manufacture, silk filter material, silk filter material, silk filter material, silk filter material, silk filter material, silk filter material, fiber filter material, silk filter material, silk filter material, fiber filter material, silk filter material, fiber filter material, silk filter material, fiber filter material, fiber filter material, fiber filter material, etc. Material, multifilament cloth and filter material; according to the organization, it can be divided into: twill plain woven cloth, twill woven cloth.

Materials such as raw fibers play a major role in determining the efficacy of machine filter materials in terms of the good structure and organizational form of the material. Machine filter fabrics have the advantages of repeatability, high wear resistance, usability, easy cleaning, and tension control.

However, the woven filter material is a two-dimensional plane filter material. Due to the high linear density of the yarn in the filter cloth, it is difficult for the fluid to pass throught the gaps between the yarns or fibers, but only throught the pores between the warp and weft. Although the pores are large and straight through, so that the resistance to the fluid is small, its 30% to 40- % porosity is difficult to meet some high-precision filtration, so the woven filter material the filtration resistance is still relatively large.

In addition, it is difficult for the mechanism filter material to form a filter cake, because at the beginning of the filtration , the woven filter material is not easy to cut the smaller particles , and can only cut some slightly larger particles ,and can only cut some slightly larger particles so that the woven filter material will soon be blocked, resulting in filtration resistance is significantly increased .Therefore, wovwn filter materials have both advantages and disadvantages.

In addition, the structure of the woven filter material and the difference of the raw materials make it used in different occasions .The difference of these two factors has a great influence on the physical and mechanical performance and filtration charaacteristics of the woven filter material . Generally,ordinary chemical fibers such as polyester , polypropylene , nylon and other fibers and glass fibers are used in some case where the performance is not very high ; while some high -performance fibers such as carbon fiber,polytetrafluoroethylene fiber (PTFE), polyphenylene sulfide(ppS),basalt fiber, etc. are used under the conditions of some special filtering occasions.
