Non-woven fabrics are made of chemical fibers and plant fibers on a wet or dry paper machine with water or air as a suspending medium. Although they are cloth and not woven, they are called non-woven cloth. Non-woven fabric is a new generation of environmentally friendly materials, which has the advantages of good strength, breathable and waterproof, environmental protection, flexibility, non-toxic and tasteless, and low price. It is a new generation of environmentally friendly materials with the characteristics of water repellency, breathability, flexibility, non-combustion support, non-toxic and non-irritating, and rich colors. If the material is placed outdoors and decomposed naturally, its longest life is only 90 days, and it will decompose within 8 years when placed indoors. It is non-toxic and harmless when burning, so it does not pollute the environment, so environmental protection comes from this.

Process flow of non-woven fabrics:

The first step is to manufacture polyester and polypropylene raw materials, which are carded, combed, pre-needled, and main-needled. A mesh cloth interlayer is added in the center, and then double-tracked, air-laid and needle-punched to form a cloth, and the filter cloth has a three-dimensional structure and is heat-set.

After the second step of singeing, the surface is most treated with chemical oil, so that the surface of the filter cloth is smooth, the micropores are evenly distributed, the density of the product is good from the surface, and the surfaces on both sides are smooth and air-permeable. Well, it has been proved by the filter on the plate and frame compressor. It can use high pressure and the filtration accuracy is up to 4 microns. Two kinds of raw materials, polypropylene and polyester, can be provided according to user needs.

The third step has proved that non-woven filter cloth has better performance in plate and frame filtration: for example, coal slime treatment in coal preparation plants, and wastewater treatment in iron and steel plants. Wastewater treatment in breweries, printing and dyeing plants. If other specifications of filter cloth are used, the filter cake will not be pressed dry, and it will be difficult to fall off. After using non-woven filter cloth, the filter cake is quite dry when the filter pressure reaches 10kg-12kg, and the filter cake when the filter frame is opened. will fall off automatically. When users choose non-woven filter cloth, they mainly consider non-woven filter cloth of different thickness and quality according to the air permeability, filtration accuracy, elongation, etc., and the specifications and varieties can be formulated.

Non-woven manufacturers, needle-punched non-woven products are formed by fine carding, repeated precision needle punching or appropriate hot rolling treatment. Based on the introduction of two high-precision acupuncture production lines at home and abroad, high-quality fibers are selected. Through the coordination of different production processes and the matching of different materials, hundreds of different products are currently circulating on the market.
