DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] Please refer to Figure 1 This embodiment provides a non-woven fabric structure, including a first non-woven fabric layer 1, a water-absorbing layer 2, and a second non-woven fabric layer 3 stacked in sequence from bottom to top.

[0036] The water absorbing layer 2 includes a first water absorbing layer 21, a water storage layer 22, and a second water absorbing layer 23 which are stacked in sequence from bottom to top. The first water absorbing layer 21 and the second water absorbing layer 23 are both made of super absorbent fibers and have good water absorbing properties. Taking the first water absorbing layer 21 as an example, the first water absorbing layer 21 is also filled with a water absorbing factor 211 made of a high molecular water absorbing resin, which further enhances the water absorbing effect; the second water absorbing layer 23 is the same.

[0037] Please combine Figure 1 and Figure 3 The water storage layer 22 is made of sponge and is provided with a water storage cavity 222 for storing water. In order to introduce the water absorbed by the first water absorption layer 21 and the second water absorption layer 23 into the water storage layer 22 for storage, a plurality of moisture conducting strips 4 are provided in the water storage layer 22. The main part of the moisture conducting strips 4 is located in the water storage layer 22. The two ends of the moisture conducting strips 4 are in contact with the first water absorption layer 21 and the second water absorption layer 23 respectively, so as to introduce the water in the first water absorption layer 21 and the second water absorption layer 23 into the water storage layer 22.

[0038] In order to install the moisture guide strip 4, a first installation groove 221 for installing the moisture guide strip 4 is also provided in the water storage layer 22, and the water storage cavity 222 is connected with all the first installation grooves 221 to form a channel for water circulation. It is worth mentioning that the first installation groove 221 and the moisture guide strip 4 are structures with a raised middle part, which are stable to install and not easy to fall off.

[0039] Due to the presence of the water storage cavity 222, after the non-woven fabric absorbs a large amount of water, the fabric will swell, which will greatly reduce the service life of the fabric in the long run. In order to avoid excessive deformation of the fabric, the present embodiment also provides a tensile rope 5 in the moisture-conducting strip 4, and the two ends of the tensile rope 5 are respectively passed through the two ends of the moisture-conducting strip 4 and fixedly connected to the limiting ball 51. After the moisture-conducting strip 4 absorbs a large amount of water and swells, the tensile rope 5 is tightened to limit further deformation of the fabric. At the same time, the limiting ball 51 is squeezed on the part where the moisture-conducting strip 4 extends into the first water absorption layer 21 and the second water absorption layer 23 to prevent the water inside the water storage layer 22 from flowing back, further ensuring the durability of the water absorption performance.

[0040] In an environment with sufficient water, bacteria are easy to breed. In order to enhance the antibacterial performance, the anti-pull rope 5 is made of silver fiber, which can achieve a sterilization effect. At the same time, an antibacterial layer made of bamboo fiber is also arranged between the water storage layer 22 and at least one of the first water absorption layer 21 and the second water absorption layer 23. The bamboo fiber has natural antibacterial, antibacterial, mite removal, deodorization and anti-ultraviolet functions, and can effectively inhibit bacteria and prevent the growth of bacteria. As shown in this embodiment, the two sides of the water storage layer 22 are bonded with an antibacterial layer 61 and an antibacterial layer 62 respectively. Taking the antibacterial layer 61 as an example, an antibacterial capsule 611 is arranged in the antibacterial layer 61, and the antibacterial capsule 611 is filled with an antibacterial agent.

[0041] like Figure 1 and Figure 2 As shown, the moisture conducting strip 4 is formed by the first moisture conducting component 41 and the second moisture conducting component 42. A first through hole 411 for the two ends of the second moisture conducting component 42 to pass through is provided on the first moisture conducting component 41 near the first water absorbing layer 21 and the second water absorbing layer 23, and a second through hole 421 is vertically provided on the part of the second moisture conducting component 42 located in the first through hole 411; the second through hole 421 and the gap 43 between the main part of the first moisture conducting component 41 and the main part of the second moisture conducting component 42 together constitute a second installation groove 44 for the anti-pull rope 5 to pass through. In order to increase the contact area between the two ends of the moisture conducting strip 4 and the first water absorbing layer 21 and the second water absorbing layer 23, thereby enhancing the moisture conducting performance, the two ends of the first moisture conducting component 41 are located at the part of the first water absorbing layer 21 and the second water absorbing layer 23, and extend to one side of the main part of the second moisture conducting component 42. Similarly, two ends of the second moisture conducting component 42 are located between the first water absorbing layer 21 and the second water absorbing layer 23 , and extend toward one side of the main body of the first moisture conducting component 41 .

[0042] Embodiment 2:

[0043] This embodiment provides a method for manufacturing a non-woven fabric structure, comprising the following steps:

[0044] S1, such as Figure 3 As shown, a water storage cavity 222 and a first installation groove 221 are opened at corresponding positions in the water storage layer 22;

[0045] S2, such as Figure 4 As shown, a first through hole 411 and a second through hole 421 are respectively provided at fixed positions of the first moisture conducting component 41 and the second moisture conducting component 42. The opening position and shape of the first through hole 411 are determined by the first moisture conducting component 41 and the second moisture conducting component 42 being embraced so as to facilitate the passage of the second moisture conducting component 42; similarly, the opening position and shape of the second through hole 421 are determined by the second through hole 421 being in a vertical direction and facilitating the passage of the tensile cord 5 after the first moisture conducting component 41 and the second moisture conducting component 42 are embraced.

[0046] S3, such as Figure 5 As shown, the first moisture conducting component 41 and the second moisture conducting component 42 are sequentially placed into the first installation groove 221;

[0047] S4, such as Figure 6 As shown, the antibacterial layer 61 and the antibacterial layer 62 are respectively bonded to the upper side and the lower side of the water storage layer 22. The antibacterial layer 62 and the antibacterial layer 61 are preset with antibacterial capsules filled with antibacterial agents.

[0048] like Figure 7 As shown, the two ends of the second moisture-conducting component 42 are then passed through the first through hole 411 and extended toward the main body of the first moisture-conducting component 41; at the same time, the two ends of the first moisture-conducting component 41 are extended toward the main body of the second moisture-conducting component 42; this step forms a second installation groove 44 for the tensile rope 5 to pass through.

[0049] S5, such as Figure 8 As shown, one end of the tension rope 5 is fixedly connected to the limiting ball 51, and the tension rope 5 is passed through the second installation groove 44 and then fixedly connected to the other limiting ball 51, thereby completing the installation of the moisture-conducting strip 4;

[0050] S6, such as Fig. 9 As shown, the first water-absorbing layer 21, the second water-absorbing layer 23, the first non-woven fabric layer 1, and the second non-woven fabric layer 3 are bonded in sequence to complete the production of the non-woven fabric.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
