Description

Technical Field

[0001] The invention relates to the technical field of spunlace nonwoven fabrics, and in particular to a spunlace nonwoven fabric atomization modification device and a process thereof. Background Art

[0002] In the process of manufacturing spunlace non-woven fabrics, an atomizing device is often used to spray high-pressure water through a spunlace head to form multiple fine water jets, which are then shot toward the pre-formed fiber web. The water jets cause a portion of the surface fibers in the fiber web to displace, intersperse, entangle, and embrace. Under the dual effects of the water jet impact and the rebounding water flow, the fibers in the fiber web form countless flexible entanglement points, thereby reinforcing the fiber web.

[0003] For example, the existing application number: CN202011382542.1 discloses a hydroentanglement machine for non-woven fabrics, including a bottom plate, a first side plate, a second side plate, a spray box, a spray rod, a U-shaped water baffle and a water circulation mechanism; a conveying roller and a winding roller are arranged between the second side plates, and the non-woven fabric is wound between the conveying roller and the winding roller; a sprocket mechanism is installed on the rotating shaft of the winding roller, and the sprocket mechanism includes a first sprocket, a second sprocket and a transmission chain, and a turntable is coaxially fixedly installed on the second sprocket, and a transmission rod is hinged at an eccentric position of the turntable, and the other end of the transmission rod is hinged to one end of the fixed shaft at the center of the conveying roller. The U-shaped baffle can prevent water from splashing out during processing, and the water circulation mechanism can recycle water; the distance between the conveying roller and the winding roller will change continuously, so that the non-woven fabric can be stretched and contracted, thereby changing the fiber distribution in the non-woven fabric, so that the high-pressure clustered water can fully hydroentangle the non-woven fabric.

[0004] However, due to the different strength, thickness, flexibility and other characteristics of different fibers, their ability to withstand hydroentanglement pressure and the required entanglement force are also different. Therefore, before production, the pressure of the hydroentanglement head needs to be adjusted according to the fiber raw materials used. When adjusting the pressure of the hydroentanglement head, the operator is required to replace the hydroentanglement head with different apertures according to the required pressure. Not only is the operation more troublesome and increases the workload of the operator, but it also affects the efficiency of adjusting the hydroentanglement pressure and the production and processing progress of the hydroentanglement non-woven fabric. Summary of the invention

[0005] In view of this, the present invention provides a spunlace non-woven fabric atomization modification device and a process thereof, which can quickly control and adjust the aperture sizes of multiple spunlace heads, thereby improving the convenience of operation when adjusting the pressure of the spunlace heads, reducing the workload of operators, improving the efficiency of adjusting the spunlace pressure, and further improving the production and processing progress of the spunlace non-woven fabric. At the same time, when the water jet impacts the fiber web, there is both a vertical force to make the fibers entangled in the vertical plane, and a horizontal force to push the fibers to move and arrange in the horizontal plane, so that the fiber web is impacted by water jets from different angles, thereby enhancing the fiber entanglement effect in the vertical plane, realizing double-directional water guidance, and improving the softness and skin-friendliness of the non-woven fabric.
