Water-absorbing pad with mildew-proof function

Abstract

This invention provides an absorbent pad with anti-mildew function, comprising a base fabric, an antibacterial pack, and a desiccant pack. The antibacterial pack and desiccant pack contain pulp fiber, activated alumina, a polymer, and a photocatalyst, with the following proportions: pulp fiber 5%–10%, activated alumina 5%–15%, polymer 30%–40%, and photocatalyst 20%–30%. The base fabric is made of meltblown fabric, with structural strips on both sides. The antibacterial pack is fixed to both ends of one side of the base fabric, forming a cavity between the antibacterial pack and the base fabric, into which the desiccant pack is placed. In use, bending the structural strips causes the desiccant packs at both ends of the base fabric to face different directions, creating a multi-directional contact surface between the photocatalyst, activated alumina, pulp fiber, and polymer. This enhances the efficiency of the photocatalyst in degrading harmful gases while simultaneously strengthening the three-dimensional network water absorption capacity and moisture-proof effect of the polymer.

Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to an absorbent pad with anti-mildew function. Background Technology

[0002] Existing desiccants mostly use a single adsorbent material (such as silica gel or activated carbon) or a fixed structure design. Although they have basic moisture absorption and mildew prevention functions, they are limited by planar layout and fixed shape, resulting in limited material exposure area, low moisture absorption efficiency, and limited range of mildew prevention. Utility Model Content

[0003] To address the shortcomings mentioned above in the background technology, this utility model provides an absorbent pad with anti-mildew function.

[0004] The present invention adopts the following technical solution: An absorbent pad with anti-mildew function, the absorbent pad comprising: A base fabric, wherein structural strips are provided on both sides of the base fabric, and the shape of the structural strips is adjustable; A sterilization pack, wherein a photocatalyst is built into the sterilization pack, and the sterilization pack is fixed at both ends of one side of the base fabric, and an accommodating cavity is formed between the sterilization pack and the base fabric; A drying package containing activated alumina, pulp fibers, and a polymer. The sterilization pack is provided at both ends of the structural strip on the same side of the base fabric, so that each end of the same side of the base fabric has a receiving cavity, and the drying pack is embedded in both receiving cavities.

[0005] In one possible implementation, the base fabric has a through-hole at the location of the accommodating cavity corresponding to the location of the polymer, and cobalt chloride test paper is pasted and fixed inside the accommodating cavity at the location of the through-hole.

[0006] In one possible implementation, a row of first connecting holes is distributed along the side of the base fabric, and the structural strip passes through each of the first connecting holes in sequence.

[0007] In one possible implementation, the structural strip is an aluminum strip, and the aluminum strip is wrapped with a plastic protective layer.

[0008] In one possible implementation, the accommodating cavity has an opening at a position corresponding to one of the structural strips, and the drying package is embedded into the accommodating cavity through the opening; the sterilization package has a flat extension on one side of the opening, and the extension and the side of the base fabric cover the structural strip, thereby fixing the extension and the structural strip.

[0009] In one possible implementation, the side of the base fabric is rolled up to cover the extension, and then the structural strip is bent relative to the base fabric.

[0010] In one possible implementation, a row of first connecting holes is provided on the side of the base fabric, and a row of second connecting holes is provided on the extension. The extension is superimposed on the base fabric, and the structural strip passes through each of the first connecting holes and each of the second connecting holes in sequence.

[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model uses manual bending (such as folding both ends to form a triangular support) to make the sterilization pack and drying pack at both ends of the base fabric face different directions. This structure allows the photocatalyst, activated alumina, pulp fiber, and polymer to form a multi-directional contact surface, which not only expands the contact range with air and accelerates the moisture absorption and mildew prevention reaction, but also avoids dead corners in material contact caused by planar stacking through the three-dimensional shape, thereby improving the efficiency of photocatalytic degradation of harmful gases. At the same time, it strengthens the three-dimensional network water absorption capacity and anti-dampness effect of the polymer in the drying pack. Attached Figure Description

[0018] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0019] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0020] This utility model provides an absorbent pad with anti-mildew function, as shown in the attached... Figure 1 and 2 As shown, the absorbent pad includes a base fabric 1, a sterilization pack 2, and a drying pack 3. The base fabric 1 is made of meltblown fabric, and the sterilization pack 2 is fixed to both ends of one side of the base fabric 1. A receiving cavity 101 is formed between the sterilization pack 2 and the base fabric 1, and the absorbent drying pack 3 is placed inside the receiving cavity 101.

[0021] As attached Figure 2 As shown, the sterilization bag 2 is a cloth bag structure made of non-woven fabric 21, and the sterilization bag 2 is filled with photocatalyst. The non-woven fabric 21 can be a 16g / m² white non-woven fabric with a light transmittance of 85.6%. Preferably, the photocatalyst can be titanium dioxide, which produces a strong oxidizing substance (such as hydroxyl radicals, oxygen, etc.) under light irradiation, and can be used to decompose organic compounds, some inorganic compounds, bacteria, and viruses. In daily life, photocatalysts can effectively degrade toxic and harmful gases in the air, such as formaldehyde, and efficiently purify the air; at the same time, they can effectively kill a variety of bacteria and decompose and neutralize the toxins released by bacteria or fungi.

[0022] Please refer to the appendix. Figure 4 The sterilization bag 2 can be a flat cloth bag structure formed by fixing two pieces of non-woven fabric 21 together by ultrasonic welding, and the two pieces of non-woven fabric 21 cover the photocatalyst to form a structure in which the photocatalyst is filled inside the sterilization bag 2. In addition, the area of ​​one piece of non-woven fabric 21 is larger than that of the other piece of non-woven fabric 21, so that the edge of the larger piece of non-woven fabric 21 can also be fixed to the base fabric 1 by ultrasonic welding, thereby fixing the sterilization bag 2 to one side of the base fabric 1.

[0023] The drying package 3 can also be a cloth bag structure formed by fixing two pieces of non-woven fabric 21 together by ultrasonic welding, and the drying package 3 contains a polymer, activated alumina, and pulp fiber. Preferably, the proportions of each component in this invention are as follows: pulp fiber 5%–10%, activated alumina 5%–15%, polymer 30%–40%, and photocatalyst 20%–30%. The polymer can be a SPA polymer, such as sodium polyacrylate. When this invention is placed in a humid environment, the polymer forms a three-dimensional network structure through inter-chain cross-linking, enabling it to absorb water up to hundreds of times its own weight. Furthermore, the polymer gels after absorbing water, preventing liquid seepage and moisture return, thus achieving a water-absorbing and drying effect. In addition, the base fabric 1 has a through-hole 103 at the location corresponding to the polymer accommodating cavity 101, and cobalt chloride test paper 5 is adhered and fixed within the cavity 101 at the location of the accommodating window. Once the polymer absorbs sufficient moisture to form a gel, the desiccant continues to absorb water, keeping the desiccant 3 moist. When the desiccant 3 comes into contact with the cobalt chloride test paper 5, the cobalt chloride test paper 5 will change color (blue when humidity is <50%, pink when humidity is >70%). By observing the color change of the cobalt chloride test paper 5, the current moisture absorption state of the desiccant 3 can be known, making it easier to determine the replacement cycle of the desiccant 3.

[0024] Continue to refer to the appendix Figure 1 A row of first connecting holes 102 is distributed along the side of the base fabric 1. The structural strip 4 passes through each of the first connecting holes 102 in sequence, thereby confining the structural strip 4 to the side of the base fabric 1. The arrangement and shape of the base fabric 1 can be changed by bending the structural strip 4. For example, bending both ends of the structural strip 4 makes the two ends of the base fabric 1 relatively inclined, thereby forming an attached... Figure 5 The triangular structure shown is placed on a plane. This structure allows the sterilization pack 2 and the drying pack 3, which are set at both ends of the base fabric 1, to face two different directions. Compared with the whole flat method, this is conducive to faster contact with air and achieving efficient anti-mildew and drying functions.

[0025] Preferably, the structural strip 4 is an aluminum strip, and the aluminum strip is wrapped with a plastic protective layer. Utilizing the plasticity of aluminum, the structural strip 4 can be bent into a stable shape, realizing the transformation of the base fabric 1 from a planar to a three-dimensional form. Furthermore, the plastic coating not only protects the metal strip but also enhances the frictional locking effect with the first connecting hole 102, ensuring the stability of the three-dimensional form and maximizing the synergistic anti-mildew drying efficiency of the multi-component materials.

[0026] Because photocatalysts and polymers are reusable, this invention can be reused repeatedly. Specifically, the antibacterial pack 2 can regain its anti-mildew and moisture-absorbing properties by air drying, and its cycle life is 2-3 years. The drying pack 3 can be dehydrated by microwave, restoring the activity of the polymer that has absorbed water and formed a gel state. Afterwards, the drying pack 3 can be placed back into the receiving cavity 101, and the opening of the receiving cavity 101 can be sealed for reuse. The method of sealing the opening of the receiving cavity 101 can be as shown in the attached figure. Figure 3 As shown, the sterilization pack 2 has a flat extension 22 on one side of the opening. Specifically, the extension 22 can be one side of a large piece of non-woven fabric 21. After the structural strip 4 is rolled up on the side of the base fabric 1 to cover the extension 22, the opening of the receiving cavity 101 can be sealed. Then, the structural strip 4 is bent relative to the base fabric 1, for example, by bending both ends of the structural strip 4 180° towards the middle, or by bending the structural strip 4 as shown in the attached figure. Figure 5 The bending shown prevents the sterilization pack 2 from opening, thus fixing the drying pack 3 inside the sterilization pack 2 and securing the drying pack 3.

[0027] Alternatively, the opening of the accommodating cavity 101 can be sealed in the following manner. Figure 4 As shown, the extension 22 is provided with a row of second connecting holes 201. After the extension 22 is superimposed on the base fabric 1, the structural strip 4 is passed through each first connecting hole 102 and each second connecting hole 201 in sequence, thereby sealing the opening of the accommodating cavity 101. This method can seal the opening of the accommodating cavity 101 without bending the structural strip 4.

[0028] In summary, this invention achieves a three-dimensional shape transformation of the base fabric 1 through the plastic bending design of the structural strip 4 on the side of the base fabric 1. Specifically, by manually bending (such as folding the two ends to form a triangular support), the sterilization pack 2 and the desiccant pack 3, which are set at both ends of the base fabric 1, face different directions. This structure allows the photocatalyst, activated alumina, pulp fiber, and polymer to form a multi-directional contact surface, which not only expands the contact range with air and accelerates the moisture absorption and mildew prevention reaction, but also avoids dead corners in material contact caused by planar stacking through the three-dimensional shape, thereby improving the efficiency of photocatalytic degradation of harmful gases, while strengthening the three-dimensional network water absorption capacity and anti-dampness effect of the polymer in the desiccant pack 3.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
