With the iterative and renewal of textile technology, the ‘double-layer monofilament filter cloth’ came out. It is woven with two different diameter monofilaments in two layers at the same time, and the two layers are connected by joints. The layer with small monofilament diameter and high density serves as the filter layer, and the layer with large monofilament diameter and low density serves as the support layer.
In this way, the problems of thinness, low strength, softness and poor stiffness of the monofilament filter cloth with high filtration accuracy are solved, and the disadvantages of low filtration accuracy of the large-diameter monofilament filter cloth are also avoided. The double-layer monofilament filter cloth has a good application effect on various filtering equipment. The double-layer monofilament filter cloth is made of polypropylene and polyester.
Polypropylene double-layer monofilament filter cloth is a kind of melt-spun fiber. It has excellent acid and alkali resistance, strong controllability of strength and stretch, abrasion resistance, good chemical stability, and good moisture absorption ability. In actual use, the filter life is relatively long.It can filter materials with high viscosity, and has a wider range of applications.
