To save water and reduce production costs, about 98% of the process water must be recycled after water treatment. Because the production water source contains some impurities, fiber shedding may occur when high-speed water jet impacts the fiber web, especially the impurities and short fibers of cotton and wood pulp fibers. In addition, various types of oil (auxiliary) agents of chemical fibers may also remain in the water after spunlace, and the reproduction of microorganisms in the water may affect water quality, causing the spray holes of the spray plate to be blocked, thereby seriously affecting the quality and appearance of the product. Therefore, the water filtration system is a very important part of spunlace production.

[0003] The metal filter is a new type of wire-wound tube filtration system. Liquid flows in through the inlet, is filtered through the screen pipe, and then flows out from the outlet. Impurities are intercepted outside the screen pipe. The main interception is of short fibers and solid particles larger than 20 μm, thereby reducing the replacement frequency of the filter bag of the subsequent single-bag filter.

[0004] However, the pores of the screen pipe of the metal filter of the prior art may be blocked by impurities after long-term use, resulting in a decrease in sewage flow.
