Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] Please see the attached Figure 1 -Attached Figure 5 , the embodiment of the present invention provides a directional arrangement device for water-jet reinforced fibers, including a reflective plate 4, a cylindrical connecting shaft 5 is arranged around the reflective plate 4, a cylindrical connecting shaft fixing rod sleeve 9 is sleeved on the surface of the cylindrical connecting shaft 5, a fixed rod 3 is fixedly connected to the top of the surface of the cylindrical connecting shaft fixing rod sleeve 9, a cylindrical connecting shaft reflecting plate sleeve 10 is arranged on the opposite side of the cylindrical connecting shaft fixing rod sleeve 9 on the adjacent side, the cylindrical connecting shaft reflecting plate sleeve 10 is fixedly connected to the reflective plate 4, a water-jet head 1 is arranged between the four fixing rods 3, and a water-jet head 1 is arranged at the bottom of the reflective plate 4. A spunlace mesh curtain 6 is provided, a vacuum suction device 7 is provided at the bottom of the spunlace mesh curtain 6, a water needle plate 2 is provided at the bottom inner side of the spunlace head 1, the water needle plate 2 is provided with evenly distributed water needle holes 11, a fiber mesh 14 is provided on the top of the reflective plate 4, and the top of the surface of the four fixing rods 3 are provided with fixing rod threads 8, the reflective plate 4 is provided with evenly distributed reflective plate drainage holes 15, the top of the reflective plate 4 is fixedly connected with evenly distributed reflective plate directional patterns 13, the reflective plate drainage holes 15 and the reflective plate directional patterns 13 are staggered, and a water needle 12 is provided between the water needle plate 2 and the reflective plate 4.

[0026] The water jet head 1 and the water jet plate 2 are a combination device. The water jet head 1 can produce a stable water jet curtain. The water jet head 1 can make the water jet curtain have different densities and diameters by replacing different water jet plates 2; the reflector 4 fixes the relative position of the reflector 4 and the water jet head 1 through the fixing rod 3, and the reflector 4 adjusts the distance from the water jet head 1 through the fixing rod 3; the connection between the reflector 4 and the fixing rod 3 can make the reflector 4 deflect in a circle through the distance difference between the fixing rod 3, and has a certain inclination, and the connection between the reflector 4 and the fixing rod 3 is a loose buckle, and the connection between the fixing rod 3 and the water jet head 1 is a loose buckle and the distance between the water jet head 1 and one side of the reflector 4 can be adjusted; the water jet mesh curtain 6 is a fiber web 14 conveying device. When carrying the fiber web 14 through the reflector 4, the fiber web 14 passes over the reflector 4, and the water jet mesh curtain 6 passes from the reflector The reflective plate 4 passes under the water jet board 4; the vacuum suction device 7 is located below the reflective plate 4 and the water spunlace curtain 6; the needle hole on the water jet board 2 is a set water jet hole 11, and the reflective plate 4 is set with a reflective plate directional pattern 13. The front and back sides of the reflective plate 4 are provided with a transparent small air hole reflective plate drainage hole 15. The water jet hole 11 on the water jet board 2 is reflected by the reflective plate directional pattern 13 on the reflective plate 4, so that the landing direction of the water needle 12 generated by the water jet head 1 through the water jet board 2 is the reflective plate directional pattern 13 of the reflective plate 4; the water needle 12 generated by the water jet head 1 through the water jet board 2 pierces the fiber web 14 at a certain angle, and then passes through the reflective plate directional pattern 13 of the reflective plate 4, directionally changing the movement trajectory of the water needle 12, so that part of the fibers in the fiber web 14 are distributed along the predetermined movement trajectory of the water needle 12, thereby realizing the directional distribution of the fibers in the fiber web 14.

[0027] By replacing different needle plates 2, the water jets 12 produced by the water jet head 1 have different diameters. The distribution of the needle holes 11 on the water jet plate 2 also creates a water jet curtain with varying densities. The water jets 12, along with the energy they carry, follow a predetermined trajectory. This is achieved by matching the needle holes 11 in the water jet plate 2 with the directional patterns of the reflector 4. After being ejected, the water jets 12 reach the predetermined directional patterns in the reflector 4, changing their direction. This allows for controllable energy levels in the water jets 12 reflected by the reflector 4, enabling both the energy of the unreflected and reflected water jets 12 to be controlled.

[0028] The two ends of the fixing rod 3 are respectively connected to the reflecting plate 4 and the water jet head 1 so that the distance between the reflecting plate 4 and the water jet head 1 is fixed.

[0029] The reflective plate 4 can be deflected by moving the fixed rod in the vertical direction. The connection between the fixed rod 3 and the water jet head 1 can adjust the distance between the reflective plate 4 connected by the fixed rod 3 and the water jet head 1. The fixed rod 3 increases the controllable direction and angle of the energy of the water needle 12 reflected by the reflective plate 4 by adjusting the distance between the reflective plate 4 and the water jet head 1.

[0030] The spunlace screen 6 transports the web 14 to be spunlace. As the web 14 passes over the reflector 4, it passes above it, while the spunlace screen 6 passes below it. The spunlace screen 6 pulls the web 14 between the reflector 4 and the spunlace head 1, completing the spunlace without affecting the web's continued movement.

[0031] The vacuum suction device 7 is located below the spunlace mesh curtain 6 and the reflective plate 4. The vacuum suction device 7 sucks the spunlace water that has lost its entanglement ability through the spunlace mesh curtain 6 and the reflective plate 4. The vacuum suction device 7 sucks away the moisture carried by the fiber web 14 itself and the residual moisture from the spunlace, which does not affect the next step of the process. The vacuum suction device 7 can be a conventional vacuum suction device 7 for spunlace production. The purpose is to suck away the moisture carried by the fiber web 14 itself and the residual moisture from the spunlace when the spunlace is completed, which does not affect the next step of the process.

[0032] The needle holes on the water needle plate 2 are needle holes set according to requirements, and the reflective plate directional texture 13 on the reflective plate 4 is a texture set according to requirements. The position, diameter, and density of the needle holes on the water needle plate 2 correspond to the reflective plate directional texture 13 on the reflective plate. The landing direction of the water needle 12 is consistent with the directional texture of the reflective plate 4, so that the water needle 12 undergoes a directional change when it touches the reflective plate directional texture 13 on the reflective plate 4, so that the deflection direction of each water needle touching the reflective plate 4 conforms to the established water needle movement trajectory. The matching of the water needle 2 and the reflective plate 4 can make the fibers produce a directional arrangement during reinforcement without affecting the basis weight of the product, and make the greatest use of the entangled fibers to achieve more ideal physical and chemical indicators.

[0033] When the messy fibers in the fiber web 14 are hydroentangled, some of the fibers are carried by the water needles 12 and changed. By solidifying the movement trajectory of the water needles 12, the directional arrangement of the fibers in the fiber web 14 is achieved.

[0034] The water needle hole 11 on the water needle plate 2 penetrates downward from the top of the water needle plate 2, so that the water needle hole 11 penetrates up and down the upper water needle plate 2. The reflector 4 is arranged above and below the water needle plate 2. The drainage hole 15 on the reflector 4 also penetrates the reflector 4. The water needle plate 2 and the reflector 4 are in the same direction.

[0035] The water jet head 1 can be any conventional water jet head 1 used in water jet production, and its purpose is to generate water jet needles 12 carrying stable water jet energy after the water jet plate 2 is installed.

[0036] The matching of the water needle plate 2 and the reflective plate 4, the aperture, density and arrangement of the water needle holes in the water needle plate 2 need to be matched with the directional texture of the reflective plate 4. When the water needle 12 is sprayed to the directional texture of the reflective plate 4, the angle and shape of the contact between the directional texture and the water needle 12, as well as the inclination angle of the reflective plate itself, and the contact angle can be an inclined surface, a curved surface, a vertical surface, a sharp angle, and the angle and direction of contact and reflection can be arbitrarily set, so that the reflection direction and angle of the water needle 12 can be realized to the greatest extent; in the reflective area of ​​the reflective plate 4 that is not contacted by the water needle 12, drainage holes are provided to allow the moisture carried by the fiber web itself and remaining after water puncture to be discharged from the holes.

[0037] The fixing rod 3 has two ends connecting the water jet head 1 and the reflective plate 4. The four corners of the water jet head 1 are connected to the reflective plate 4 through the fixing rod 3. The connection between the fixing rod 3 and the reflective plate 4 is fixed by a cylindrical or spherical sleeve, so that the reflective plate 4 has a basis for free deflection. The connection between the fixing rod 3 and the water jet head 1 is connected by a screw. By rotating the screw of the fixing rod 3 or the matching nut connected to the water jet head 1, the fixing rod 3 is moved in the vertical direction, thereby driving the reflective plate 4, which has already provided a deflection basis, to deflect.

[0038] The materials and structures used for the hydroentanglement head 1, the hydroentanglement plate 2, and the hydroentanglement mesh 6 can be the same as those used in conventional hydroentanglement production. The fixing rod 3 is made of a lightweight, non-deformable, non-rusting, and non-corroding metal or synthetic metal to ensure its accuracy and stability, while maintaining its functionality. The reflector 4 is made of nickel-plated metal to ensure its ability to reflect the water jets.

[0039] The reinforcement method of directional fiber arrangement directly changes the ability to control fiber arrangement in wet spunlace reinforcement, from controlling the general orientation of fibers in the spunlace fabric to controlling the precise distribution direction of most fibers in the spunlace fabric, greatly improving the product competitiveness of the spunlace fabric.

[0040] refer to Figure 1 By matching the water jet head 1 and the water jet plate 2, the water jet hole 11 generated is matched with the water jet 12 on the directional texture 13 of the reflective plate. After the water jet 12 touches the directional texture 13 of the reflective plate, the preset reflection angle of the directional texture 13 of the reflective plate causes the water jet 12 to be reflected toward the preset angle, completing the movement of the water jet 12 carrying the water jet energy toward the preset motion trajectory. During the production process, when the fiber web 14 passes through the reflective plate 4, the water jet 12 on the preset motion trajectory carries the water jet energy, completing the process of fiber directional distribution in the fiber web 14.

[0041] Example 2:

[0042] Different from Example 1, the reflective plate 4 in Example 1 is deflected by the cylindrical connecting shaft 5 and the fixed rod thread 8. On the premise that the reflective plate 4 has a predetermined texture, the reflection angle of the water needle 12 after touching the directional texture 13 of the reflective plate continues to be changed, so that the water puncture reinforcement process has more dimensional reflection directions.

[0043] The fixing rod thread 8 and the cylindrical connecting shaft 5 on the fixing rod 3 may be other devices capable of achieving both movement and fixation, and are not limited to the fixing rod thread 8 and the cylindrical connecting shaft 5;

[0044] (1) At the thread 8 of the fixed rod, a servo motor can be used in combination with a gear column to achieve vertical movement of the fixed rod 3, or a hydraulic device can be used to achieve vertical movement of the fixed rod 3;

[0045] (2) At the cylindrical connecting shaft 5, the deflection of the reflector 4 can be achieved by using a bearing connection in which the bearing core sleeve and the bearing outer sleeve can be deflected, or by using a rotating shaft of a spherical joint type.

[0046] Example 3:

[0047] refer to Figure 2 When the fiber web 14 is undergoing hydroentanglement reinforcement, it passes through the side of the reflective plate 4 away from the vacuum suction device 7. During the entire hydroentanglement reinforcement process, the hydroentanglement mesh curtain 6 does not participate in the hydroentanglement reinforcement. The hydroentanglement mesh curtain 6 only serves to transport the fiber web 14 along the production direction of the production line. During this process, the fiber web is extracted by the vacuum suction device 7 through the drainage holes 15 of the reflective plate and the hydroentanglement mesh curtain 6 to remove moisture from the fiber web. This process does not have excessively high requirements for the hydroentanglement mesh curtain 6, and it only needs to achieve the purpose of transporting the fiber web 14.

[0048] This process can reduce the use cost of the spunlace mesh curtain, thereby reducing production costs.

[0049] Example 4:

[0050] refer to Figure 5 The directional lines 13 of the reflective plate 4 on the side close to the water needle plate of the present invention can also be gravure-type lines. When the fiber web 14 is processed by the water needle 12 and the reflective plate 4, a jacquard pattern is formed on the fabric surface.

[0051] When the water needle 12 reflects on the concave pattern on the reflector 4, by controlling the energy of the water needle, part of the fibers in the fiber web 14 can be gathered in the concave pattern of the reflector 4, forming jacquard-style patterns and convex patterns of the spunlace fabric.

[0052] This process can synchronize the production texture of conventional spunlace reinforcement methods without reducing the market competitiveness of the improved spunlace fabric. It can optimize the spunlace fabric reinforcement process without reducing the variety of spunlace fabric surface textures.

[0053] In addition, in the description of this specification, the word "conventional" means the equipment, devices, accessories, and processes currently used in the production of spunlace fabrics, unless otherwise explicitly stated.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
