Production system and production method of high-air-permeability composite non-woven fabric

Abstract

The invention discloses a production system and production method of a high-air-permeability composite non-woven fabric. The production system comprises a supporting table, wherein a material conveying mechanism is fixedly arranged on one side of the top end of the supporting table, an air supply mechanism is fixedly arranged on the other side of the top end of the supporting table, the edge side of the bottom end of the supporting table is fixedly connected to the edge side of the top end of a bottom plate, and one end of one side of the supporting table is fixedly connected to one end of a crawling ladder. According to the production system, a cloth spraying mechanism is matched with a wind shielding mechanism, an angle of a wind shielding cover can be adjusted, the cloth spraying mechanism can be protected and prevented from being influenced by wind power, a receiving mechanism matches an air draft mechanism, vertical movement of an air draft cover can be guaranteed, then a distance between a conveying net belt and the air draft cover is changed, therefore suction force borne by the surface of the conveying net belt is changed, under the cooperation of the wind shielding mechanism and the air draft mechanism, fibers sprayed by the cloth spraying mechanism can be more uniformly distributed on the conveying net belt, so that the gram weight distribution of the non-woven fabric is more uniform, and the quality of the non-woven fabric is ensured.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric production, and in particular relates to a production system and a production method of a highly air-permeable composite non-woven fabric. Background technique [0002] The main material of non-woven fabric is polypropylene, which has the characteristics of moisture-proof, breathable, light and thin, flame-retardant, five-toxic and tasteless, and can be used in different industries. The production process of non-woven fabrics includes spunbond method, melt-blown method, hot-rolled method, spunlace method, etc. When using melt-blown method to produce highly breathable composite non-woven fabrics, it needs to be produced by a complete production system. [0003] In the process of melt-blown non-woven fabrics, the fibers ejected from the melt-blown nozzle fall on the conveyor belt to form non-woven fabrics for transmission. During the spinning process of the melt-blown nozzle, because the fi...

Problems solved by technology

[0003] When melt-blown non-woven fabrics, the fibers ejected from the melt-blown nozzle fall on the conveyor belt to form a non-woven fabric for transmission. During the spinning process of the melt-blown nozzle , due to the lightness of the ejected fiber, it is easily affected by the external wind force, resulting in the fiber being bonded by force, which will lead to unstable production of non-woven fabrics, resulting in uneven non-woven fabrics produced and affecting product quality. After the fibers are discharged, the fibers fall on the conveyor belt under the suction of the device, which can ensure the production of non-woven fabrics. However, the suction of the device cannot be adjusted, so that personnel cannot adjust according to the production requirements of non-woven fabrics, resulting in The weight distribution of non-woven fabrics is uneven, resulting in the production of non-woven fabrics that are not up to standard. After the melt-blown nozzle is used, the spinneret hole will have residual raw materials, which will cause the spinneret hole of the melt-blown nozzle to be blocked, resulting in spraying of the melt-blown nozzle. The silk is not uniform enough, resulting in uneven production of non-woven fabrics and affecting its quality
