[0002] At present, most of the preparation of spunlace nonwovens with directional water-conducting function adopts chemical method, using hydrophilic / hydrophobic single-sided finishing or hydrophilic / hydrophobic double-sided finishing to produce hydrophilic / hydrophobic differences on both sides of the material, forming a moisture conduction gradient in the vertical direction, thereby generating a differential capillary effect to achieve directional water conduction. The single-sided water-repellent finishing methods of spunlace nonwovens include foam, impregnation, coating, plasma, electrostatic spraying, etc. After foam, impregnation and coating finishing, the softness and air permeability of the material are significantly reduced, the feel becomes hard, and the operation is difficult, it is difficult to control the amount of liquid applied, and the finishing liquid easily penetrates to the other side; the finishing time of plasma and electrostatic spraying is short, and the equipment is limited, resulting in the inability to mass-produce, and it is only suitable for the preparation of small samples in the laboratory.

The atomizing shell 29 is located in the through hole 28 , and the lower end of the atomizing shell 29 passes through the through hole 28 .

[0081] Working or installation process:

[0082] First, the non-woven fabric is subjected to multi-stage spunlacing. The first pre-spunlacing pressure is relatively low to prevent the loss of fibers due to excessive pressure and ensure the uniformity of the fiber web. Subsequently, the spunlacing pressure is increased, and the fiber web is punctured by the high-pressure water jet generated by the spunlacing machine, so that the fibers are entangled, interlaced, and displaced with each other, thereby reinforcing the fiber web and giving it a certain strength.

[0083] One end of the non-woven fabric after the multi-stage water spunlace is placed on the conveyor belt 13. According to the width of the non-woven fabric, the vertical distance between the ultrasonic atomizing nozzle 33 and the conveyor belt of the conveyor belt 13 is adjusted, and the lifting motor 21 is started. The output shaft of the lifting motor 21 drives the lifting gear 22 to rotate. The lifting gear 22 meshes with the adjusting rack 20 and drives the first slider 18 to move along the extension direction of the adjusting rack 20, thereby determining the height H1 of the ultrasonic atomizing nozzle 33 and the surface of the non-woven fabric on the conveyor belt 13;

[0084] Then, the mounting block 24 located closest to the wall of the coating chamber 12 is used as a reference. The mounting block 24 does not move, and the drive motor 26 in the mounting block 24 next to the mounting block 24 is started. The output shaft of the drive motor 26 drives the drive gear 27 to rotate. The drive gear 27 drives the mounting block 24 to move along the extension direction of the drive rack 23 by meshing with the drive rack 23. The infrared rangefinder 25 transmits infrared rays to the infrared rangefinder 25 on the mounting block 24 as the reference and performs distance measurement. The distance between the two infrared rangefinders 25 is D1, and the distance D1 between the two infrared rangefinders 25 is also the same as the nozzle distance D1 of two adjacent ultrasonic atomizing nozzles 33. The ratio of D1 to H1 is 1 to 40. According to the height of H1, the distance D1 is determined. Then, the drive motors 26 in multiple mounting blocks 24 are started in sequence, so that the multiple ultrasonic atomizing nozzles 33 located on the liquid dispensing tube 17 are all D1.

[0085] When the spacing between the multiple ultrasonic atomizing nozzles 33 is determined, the conveyor belt 13 is started, and the conveyor belt of the conveyor belt 13 drives the non-woven fabric to transmit, and one end of the non-woven fabric moves to the bottom of the multiple ultrasonic atomizing nozzles 33; the submersible pump in the liquid storage tank 15 is started, and the submersible pump draws the fluorine-free water-repellent finishing agent stored in the liquid storage tank 15 into the second hose 16, and the second hose 16 transports the fluorine-free water-repellent finishing agent to the liquid separation tube 17. The fluorine-free water-repellent finishing agent entering the liquid separation tube 17 enters the multiple first hoses 30 respectively, and the first hose 30 introduces the fluorine-free water-repellent finishing agent into the atomizing chamber 31, the filter rod 32 filters the fluorine-free water-repellent finishing agent and starts the ultrasonic atomizing nozzle 33, and the fluorine-free water-repellent finishing agent is atomized by the ultrasonic atomizing nozzle 33 to produce atomized particles with a particle size of about 5-60 microns.

[0086] The ultrasonic atomizing nozzle 33 sprays the fluorine-free water-repellent finishing agent downwards, and the fluorine-free water-repellent finishing agent is sprayed on the non-woven fabric in a circular shape (the spraying cross section is a trapezoidal shape). Two adjacent ultrasonic atomizing nozzles 33 spray the fluorine-free water-repellent finishing agent downwards and have a partially overlapping area. The overlapping area of ​​the two adjacent ultrasonic atomizing nozzles 33 spraying the fluorine-free water-repellent finishing agent downwards is P1, and the ultrasonic atomizing spraying work is performed on the non-woven fabric through the area of ​​P1; wherein, the non-overlapping spraying area is P2;

[0087] Since two liquid dispensing tubes 17 are provided and the conveyor belt 13 conveys the non-woven fabric, the ultrasonic atomizing nozzles 33 located on the two liquid dispensing tubes 17 double-spray the non-woven fabric with the fluorine-free water-repellent finishing agent. The conveyor belt 13 transports the non-woven fabric after the spraying of the fluorine-free water-repellent finishing agent from the other end of the conveyor belt 13 to the first stable roller 38. Since the first stable roller 38 is in smooth contact with the conveyor belt 13, the dryer 39 is started at this time, and the dryer 39 dries the non-woven fabric after the spraying of the fluorine-free water-repellent finishing agent; one end of the non-woven fabric after the drying work is pulled out and wound on the winder;

[0088] As the non-woven fabric may be tilted during the process of the winder pulling the non-woven fabric, the tilt of the non-woven fabric will cause the fluorine-free water-repellent finishing agent scattered on the non-woven fabric to flow, resulting in the non-fluorine-free water-repellent finishing agent not being evenly distributed on the non-woven fabric. At this time, the stabilizing motor 41 is started, and the output shaft of the stabilizing motor 41 drives the screw rod 42 to rotate. The screw rod 42 is threadedly connected to the second slider 43 and the second slider 43 drives the second stabilizing roller 44 to move. The second stabilizing roller 44 presses the non-woven fabric to ensure that the non-woven fabric on the conveyor belt 13 and a part of the non-woven fabric passing through the dryer 39 are in a horizontal state. The distance between the two dispensing tubes 17 is large, and the ultrasonic atomizing nozzle 33 on the two dispensing tubes 17 located on the same straight line (the straight line is parallel to the conveying direction of the conveyor belt 13) will not be affected until the non-woven fabric is evenly sprayed with the fluorine-free water-repellent finishing agent and dried.

[0089] Since the width and thickness of the non-woven fabric to be sprayed are different, D1, H1 and P1 need to be adjusted each time. When the height of H1 is small, the P1 sprayed by the ultrasonic atomizing nozzle 33 (the ultrasonic atomizing nozzle 33 is located on different liquid dispensing tubes 17) located on the same straight line may overlap, resulting in uneven spraying of the fluorine-free water-repellent finishing agent. It is necessary to slightly adjust the inclination angle of the ultrasonic atomizing nozzle 33 so that the P1 located on different liquid dispensing tubes 17 and on the same conveying straight line of the conveyor belt 13 do not overlap each other. At this time, multiple adjustment motors 34 on one of the dispensing tubes 17 are started, and the output shaft of the adjustment motor 34 drives the atomizing shell 29 to rotate, and the atomizing shell 29 drives the connecting shaft 35 and the limit block 37 to rotate. Since the limit groove 36 limits the rotation of the limit block 37, the inclination angle of the atomizing shell 29 is limited, so that the spraying direction of a row of ultrasonic atomizing nozzles 33 located on the dispensing tube 17 is tilted, and the spraying angle of each ultrasonic atomizing nozzle 33 on one of the dispensing tubes 17 is tilted, so as to avoid the overlap of P1.
