Problems solved by technology

[0002] With the development of society and industry, in the fields of food, medical and chemical solid-liquid separation, the requirements for filter cloth are getting higher and higher; the current common industrial filter cloth in the market cannot meet the requirements of high temperature resistance and food or medicine at the same time. In the field of non-toxic, safe and environmentally friendly filter materials that are in direct contact with food and pharmaceuticals, in the chemical industry, filter cloths are required to withstand the environmental requirements of strong acids and alkalis at high temperatures

Embodiment 1

[0036] The polyether ether ketone monofilament has a diameter of 0.15mm, a radial density of 640 threads / 10cm, and a weft thread density of 220 threads / 10cm. After warping, it is woven on a heavyweight rapier loom. After orientation, a monofilament filter cloth with a thickness of 0.4 mm was obtained. The physical properties of the filter cloth produced in this example are shown in Table 1.

Abstract

The invention provides a method for manufacturing industrial filter cloth. The method comprises the following steps: weaving polyether ether ketone mono-filaments by a rapier loom according to a warpdensity of 360-640 / 10cm and a weft density of 120-220 / 10cm, so as to obtain blank cloth; carrying out heat setting on the blank cloth at a temperature of 220-280 DEG C and a speed of 5-10m / min to obtain the industrial filter cloth. The method adopts special plastic polyether ether ketone (PEEK) fiber which has the characteristics of high temperature resistance, chemical resistance, abrasion resistance, high strength and the like; the mono-filament filter cloth processed by the special plastic polyether ether ketone fiber is high in filtration efficiency and abrasion resistance, and can be usedfor a long time at a temperature below 260 DEG C.

Description

technical field [0001] The invention relates to a manufacturing method of an industrial filter cloth, which belongs to the technical field of separation materials. Background technique [0002] With the development of society and industry, in the fields of food, medical and chemical solid-liquid separation, the requirements for filter cloth are getting higher and higher; the current common industrial filter cloth in the market cannot meet the requirements of high temperature resistance and food or medicine at the same time. In the field of non-toxic, safe and environmentally friendly filter materials that are in direct contact with food and pharmaceuticals, in the chemical industry it is required that the filter cloth can withstand the environmental requirements of strong acid and strong alkali at high temperature. Contents of the invention [0003] The object of the present invention is to provide a polyetheretherketone (PEEK) monofilament fiber, which is woven into a mon...
