Abstract
Description
Technical Field
[0001] This utility model relates to the field of soft towel technology, and in particular to a functional soft towel that can detect the acidity and alkalinity of human skin. Background Technology
[0002] Maintaining a normal skin pH level is crucial for inhibiting the growth of harmful microorganisms. Current pH testing methods include pH test strips, pH meters, and wearable sensors, but each has its limitations. While pH test strips are simple and quick, they are susceptible to interference from impurities, oxidants, and colored substances. pH meters and wearable sensors provide accurate and precise results, but their testing processes are complex and cumbersome, and the equipment is relatively expensive.
[0003] In view of this, the applicant has innovatively designed the functional soft towel that can detect the acidity and alkalinity of human skin. Utility Model Content
[0004] The purpose of this invention is to provide a functional soft towel that can detect the acidity or alkalinity of human skin. By combining the natural acid-base indicator purple cabbage with the soft towel, the acidity or alkalinity of human skin can be detected by the color change during wiping. It has the characteristics of simple structure and convenient use.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A functional soft towel capable of detecting the acidity and alkalinity of human skin includes a soft towel and a gel layer disposed on the soft towel, wherein porous purple cabbage microcapsules are disposed on the gel layer.
[0007] The soft towel includes a base layer and a top layer, with the gel layer and purple cabbage porous microcapsules disposed between the base layer and the top layer.
[0008] The gel layer is a dried layer of a mixture of sodium alginate and anti-dyeing salt S.
[0009] The soft towel is a spunlace nonwoven fabric layer or a spunlace nonwoven fabric composite layer.
[0010] The beneficial effects of this utility model compared to the prior art are as follows:
[0011] By attaching porous purple cabbage microcapsules to the soft towel through a gel layer, the skin's pH level can be detected when wiping with the soft towel. At the same time, it can also detect whether alkaline facial cleansers and other cosmetics have been rinsed off, thus diversifying the functions of the soft towel.
[0012] By placing the gel layer and the porous purple cabbage microcapsules between the base layer and the top layer, the softness and comfort of the towel can be effectively guaranteed, and the porous purple cabbage microcapsules can be protected to prevent them from falling off and adhering to the skin.
[0013] This invention has a simple structure and is easy to use. Furthermore, purple cabbage has antioxidant properties, which helps maintain healthy skin. It is highly practical and effective, and deserves widespread promotion and use. Attached Figure Description

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example
[0021] See Figure 1-3A functional soft towel capable of detecting the acidity and alkalinity of human skin includes a soft towel 1, which is a spunlace nonwoven fabric layer or a spunlace nonwoven fabric composite layer. A gel layer 2 is provided on the soft towel 1, and purple cabbage porous microcapsules 3 are provided on the gel layer 2. The gel layer 2 is a dried layer of a mixture of sodium alginate and anti-dyeing salt S.
[0022] In this embodiment, sodium alginate is a natural polysaccharide with good biocompatibility and water solubility, which can reduce irritation to human skin and help the adhesion of purple cabbage porous microcapsules. A certain amount of anti-dyeing salt S is added to a sodium alginate solution (1%-10%) to obtain a mixture, which is then mixed with purple cabbage porous microcapsules 3 in a certain proportion and attached to the surface of spunlace fabric. It is then dried at a temperature of 25℃-100℃ to form a gel layer 2, which fixes the purple cabbage porous microcapsules 3. When in use, the skin's pH can be detected when wiping with a soft cloth, and the alkalinity of alkaline facial cleansers and other cosmetics used can also be detected as to whether they have been cleaned properly.
[0023] The reaction works because the anthocyanins in purple cabbage undergo structural changes under different acidic and alkaline conditions, thus reflecting different colors. The color change range is as follows: pink when pH < 6.5, purple when pH 6.5 < pH < 7.5, blue when pH 7.5 < pH < 8.5, and green when pH 8.5 < pH < 12. When acidic or alkaline molecules from human skin enter the porous microcapsules, they react with the purple cabbage. The color change of the purple cabbage indicates the acidity or alkalinity of the human skin. Purple cabbage also has antioxidant properties and helps maintain healthy skin. Example
[0024] See Figure 4 The difference between this embodiment and Embodiment 1 is that the soft towel 1 includes a base layer 1-1 and a surface layer 1-2, with the gel layer 2 and the purple cabbage porous microcapsules 3 disposed between the base layer 1-1 and the surface layer 1-2. The gel layer 2 serves as an adhesive layer, with the purple cabbage porous microcapsules 3 adhered to its surface. In use, after the soft towel is moistened with water, substances on the skin penetrate through the surface layer 1-2 into the purple cabbage porous microcapsules 3, enabling the detection of the skin's pH level.
[0025] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
