Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to an oleophilic and hydrophobic modified nonwoven fabric production line. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is a type of fabric formed without spinning or weaving. It is made by arranging short fibers or filaments in a directional or random manner to form a web structure, and then reinforcing it using mechanical, thermal bonding, or chemical methods. Nonwoven fabric breaks through the traditional textile principles and is widely used in various fields such as medical and health care, home decoration, industrial materials, and agricultural fabrics.

[0003] Oleophilic-hydrophobic modified nonwoven fabrics are a low-cost, high-efficiency method for treating oil stains. Typically, nonwoven fabric is used as a base to create an oleophilic-hydrophobic surface, thereby increasing the application value of the textile. Currently, the modification of nonwoven fabrics requires immersion in a treatment solution, which makes continuous production difficult during the immersion process.

[0004] CN216765139U discloses a production device for wide-width, high-strength, long-filament geotextile nonwoven fabrics, but it cannot modify nonwoven fabrics and cannot produce oleophilic and hydrophobic modified nonwoven fabrics. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings:

[0031] Example 1. As... Figures 1-4 As shown, the oleophilic and hydrophobic modified nonwoven fabric production line includes a first reactor 2 and a first rolling mill 4 installed on one side of the first reactor 2. The first reactor 2 includes a first housing 21, which has a reaction space. An inlet 22 and an outlet 27 are respectively provided on opposite side walls of the first housing 21. A first roller 23 and a fourth roller 26 are respectively located inside the inlet 22 and the outlet 27. A second roller 24 and a third roller 25 are spaced apart and located on the lower side of the reaction space. The first rolling mill 4 includes a second housing 41 and an upper roller 44 and a lower roller 43 installed inside the second housing 41. A liquid collection hopper 53 is provided on the lower side of the second housing 41, and a second drain outlet 52 is provided at the lower end of the liquid collection hopper 53.

[0032] The nonwoven fabric continuously rotates within the first reactor 2 via the first, second, third, and fourth rollers. During this rotation, it reacts with the oleophilic and hydrophobic modifying liquid within the first reactor 2, thereby improving the oleophilicity and hydrophobicity of the nonwoven fabric. After the reaction, the residual reaction liquid is removed from the nonwoven fabric via the downstream first rolling mill 4. The reaction liquid is then collected via the liquid collecting hopper 53 and discharged or recycled through the second drain port, thus improving the utilization rate of the reaction liquid and enabling continuous modification of the nonwoven fabric.

[0033] The feed inlet 42 of the second housing 41 is connected to the output port 27 of the first reactor 2; the second output port 45 of the second housing 41 is connected to downstream equipment, such as the second reactor or a dryer.

[0034] The second drain port 52 is equipped with a valve 35 and is connected to the return port 32 on one side of the first tank 21. The height of the lower end face of the collecting hopper 53 is greater than the height of the return port 32 and also greater than the liquid level in the reaction space, which facilitates the recovery and reflux of the reaction liquid; or the second drain port 52 can be connected to a waste liquid collector. The reaction liquid can be recovered or discharged depending on its usage. The reaction liquid can be a fluorine-free waterproofing agent aqueous solution, which is existing technology and will not be described further in this invention.

[0035] like Figure 2 and Figure 3 The upper end of the first housing 21 is provided with a liquid inlet 34, and a removable cover 3 is provided on the liquid inlet 34. Optionally, the upper end of the first housing 21 is provided with a balance port 31, and a filter is provided on the balance port 31 to balance the pressure in the reaction space.

[0036] Example 2. A door 28 is provided on the side wall of the first housing 21. The door 28 is hinged to the side wall of the first housing 21, and a lock 29 is provided on the door 28. For example, with the door hinged to the side wall, when the door is opened, the components inside the first housing 21 can be maintained, and the non-woven fabric 9 can also be installed.

[0037] like Figure 4 The first box 21 is provided with a first drain port 33 on its lower side; valves are provided on the return port 32 and the first drain port 33 respectively, and the valves are used to control the pipeline switch.

[0038] The second housing 41 is provided with a mounting groove 46, and guide members 47 are respectively provided on both sides of the mounting groove 46. The mounting plate 48 is detachably mounted on the guide members 47 by bolts. One side of the upper roller 44 is mounted on the mounting plate 48 by a bearing 49, which facilitates the adjustment of the distance and pressure between the upper roller 44 and the lower roller 43. The outer sides of the upper roller 44 and the lower roller 43 may be provided with an adhesive layer or a fabric layer to prevent the non-woven fabric from slipping and to facilitate the removal of moisture from the non-woven fabric.

[0039] Figure 2 The image shows a support 51 located on the lower side of the first punching machine 4, but it is not limited to this; a support may also be provided on the lower side of the first reactor 2 as needed.

[0040] Example 3. (As shown) Figure 1 This embodiment also includes a needle punching machine 1, a second reactor 61, a second binding machine 62, a dryer 7, and an edge-trimming and winding machine 8. The output end of the needle punching machine 1 is sequentially connected to the first reactor 2, the first binding machine 4, the second reactor 61, the second binding machine 62, the dryer 7, and the edge-trimming and winding machine 8. After two dips and two bindings, the oleophilic and hydrophobic modified nonwoven fabric is dried by the dryer 7 and then trimmed and wound by the edge-trimming and winding machine 8. The needle punching machine 1, the dryer, and the edge-trimming and winding machine 8 can be commercially available products. The structure of the second reactor 61 is the same as that of the first reactor 2; the structure of the second binding machine 62 is the same as that of the first binding machine 4, and will not be described again in this utility model.

[0041] The first reactor 2 and the first rolling mill are equipped with drive mechanisms 36 on their rollers, such as drive motors, synchronous belts, or conveyor belts, to drive the rotation of each roller. Some rollers are active rollers with corresponding drive mechanisms 36, while others are driven rollers. The roller driving method is existing technology and will not be described in detail here.

[0042] It should be noted that the driving speed is related to the soaking time. In one specific embodiment, the distance between the second and third rollers is 1.5-2.5 meters, preferably 2 meters, and the transmission speed of the nonwoven fabric is 0.05-0.5 meters per second, preferably 0.07 meters per second. However, this is not the limitation. The transmission speed and discharge speed, or the distance between the second and third rollers, can be adjusted according to the actual soaking time.

[0043] This invention utilizes a first reactor and a first rolling machine to achieve a single dip-and-roll operation, thereby modifying the nonwoven fabric and simultaneously refluxing or discharging the reaction solution. Similarly, a second reactor and a second rolling machine enable the continuous production of oleophilic and hydrophobic modified nonwoven fabrics through the same dip-and-roll operation.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
