Problems solved by technology

[0006] Disadvantages: poor cake removal effect of filter cloth, easy to block, poor stiffness
[0010] Disadvantages: The gap between the fibers will absorb finer filter particles during the filtration process and cause blockage
[0014] Disadvantages: low filtration accuracy, poor adhesion of solid filter residue due to the smooth surface of the fabric
Due to the poor flexibility of the monofilament, the service life of the filter cloth will be shortened due to extrusion

Embodiment 1

[0031] The woven filter cloth used in the field of solid-liquid separation requires the fabric to be stiff and stable, not easy to wrinkle and fold, and the filter residue can adhere to the surface of the fabric without falling off or passing through the filter (see Table 1).

[0032] 1. Preparation of woven industrial filter cloth:

[0033] The woven filter cloth is woven from warp yarns and weft yarns, and has a mountain-shaped twill structure. The warp yarns are 2 Φ0.15 monofilaments and 1 1000D multifilament twisted; the weft yarns are 3 Φ0.25 monofilaments and 1300D multifilaments. Composed of covered yarn.

[0034] Covered yarn is composed of core yarn and outer yarn. Its production process is mainly formed by continuously rotating the outer yarn and winding it on the core yarn that is drafted at a constant speed (see figure 1 and figure 2 ).

[0035] Depend on figure 1 It can be seen that the outer layer of the covered yarn is tightly and evenly wrapped by multifil...

Abstract

The invention relates to the field of solid-liquid separation, in particular to a machine-woven industrial filter cloth of covered yarns and production and application thereof. The machine-woven industrial filter cloth is made of the covered yarns; each covered yarn is composed of a core yarn and an outer yarn. The covered yarns are creatively applied to the machine-woven industrial filter cloth in the field of solid-liquid separation, the size of the cloth is well stable, strength of the cloth is high, and residue adhesiveness thereof is good.

Description

technical field [0001] The invention relates to the field of solid-liquid separation, in particular to a woven industrial filter cloth using covered yarn and its preparation and application. Background technique [0002] The existing woven industrial filter cloths are roughly divided into short fiber raw material filter cloths, multifilament raw material filter cloths, monofilament raw material filter cloths and single multifilament interwoven filter cloths, but all have defects of varying degrees, specifically: [0003] A. Short fiber raw material filter cloth [0004] Features: the surface of the object is more plush [0005] Advantages: It is beneficial to the attachment of filter material, and can weave filter cloth with high filtration accuracy. [0006] Disadvantages: The filter cloth has poor cake removal effect, easy to block, and poor stiffness. [0007] B. Multifilament raw material filter cloth [0008] Features: Each silk thread is composed of multiple monofi...
