Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of non-woven fabrics, and more specifically, particularly relates to a breathable weakly acidic non-woven fabric. Background Art
[0002] Non-woven fabric is a kind of non-woven fabric. It is directly made of polymer chips, short fibers or filaments through air flow or mechanical web, and then reinforced by hydroentanglement, needle punching, or hot rolling, and finally finished to form a non-woven fabric. Non-woven fabric is usually used in single-use daily necessities such as diapers, sanitary products, wipes, etc. Therefore, the market demand for non-woven fabric products is strong, which has promoted the rapid growth of non-woven fabric production capacity.
[0003] The existing publication number CN219564352U discloses a hygroscopic non-woven fabric with good air permeability. Although a semicircular protrusion is set on the top of the hygroscopic strip, the semicircular protrusion can quickly absorb moisture first, so that the moisture enters the hygroscopic block from the hygroscopic strip first, thereby improving the hygroscopic efficiency.
[0004] Based on the above, the inventors found the following problems: However, the non-woven fabric absorbs moisture through the raised moisture absorption part, which results in a slow moisture absorption rate. Not only does the top need to be provided with a protrusion but also with a ventilation hole, which results in a smaller area of the ventilation hole, resulting in a relatively poor ventilation effect. At the same time, the non-woven fabric does not have a sterilization layer, which results in a large number of bacteria inside after long-term use.
[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a breathable weakly acidic non-woven fabric is provided, in order to achieve a more practical purpose. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides a breathable weakly acidic nonwoven fabric to solve the problem that the current absorption is slow due to the provision of raised moisture absorption parts and the air permeability area is small.

[0009] Furthermore, water-absorbent cotton is arranged on the top of the outer covering layer, water-absorbent resin is arranged in the middle of the water-absorbent cotton, a plurality of the water-absorbent resins are arranged in an equidistant manner, and the water-absorbent resin is a one-way water-locking resin.
[0010] Furthermore, the first non-woven fabric layer, the antibacterial layer, the second non-woven fabric layer and the skin-friendly layer are all provided with air holes, the vertical cross-section of the air holes is trapezoidal, and the bottom of the air holes is interconnected with the top of the one-way water-locking layer.
[0011] Furthermore, the skin-friendly layer is made of high molecular weight silk peptide, and the thickness of the skin-friendly layer is 0.1 to 0.15 mm.
[0012] Furthermore, the antibacterial layer is weakly acidic cotton, and the thickness of the antibacterial layer is 0.2 to 0.3 mm.
[0013] Furthermore, the first non-woven fabric layer, the second non-woven fabric layer, the one-way water-locking layer, the outer covering layer, the antibacterial layer, and the skin-friendly layer are arranged from top to bottom in the order of skin-friendly layer, second non-woven fabric layer, antibacterial layer, first non-woven fabric layer, one-way water-locking layer, and outer covering layer.
[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0025] Example:
[0026] As attached Figure 1 To Attachment Figure 4 As shown:
[0027] The utility model provides a breathable weakly acidic non-woven fabric, comprising a first non-woven fabric layer 1 and a second non-woven fabric layer 2, an antibacterial layer 5 is arranged on the top of the first non-woven fabric layer 1, a unidirectional water-locking layer 3 is arranged on the bottom of the first non-woven fabric layer 1, an outer covering layer 4 is arranged on the bottom of the unidirectional water-locking layer 3, a skin-friendly layer 6 is arranged on the top of the second non-woven fabric layer 2, the antibacterial layer 5 is located between the first non-woven fabric layer 1 and the second non-woven fabric layer 2, and a breathable hole 8 is opened on the top of the skin-friendly layer 6.
[0028] Among them, water-absorbent cotton 71 is arranged on the top of the outer covering layer 4, and water-absorbent resin 7 is arranged inside the water-absorbent cotton 71. There are multiple water-absorbent resins 7, and the multiple water-absorbent resins 7 are filled and equidistantly arranged. The water-absorbent resin 7 adopts a unidirectional water-locking resin, which fully absorbs moisture through the unidirectional water-locking resin, quickly absorbs moisture through the water-absorbent cotton 71, and then absorbs moisture inside the water-absorbent cotton 71 through the water-absorbent resin 7.
[0029] Among them, the first non-woven fabric layer 1, the antibacterial layer 5, the second non-woven fabric layer 2 and the skin-friendly layer 6 are all provided with ventilation holes 8. The vertical cross-section of the ventilation holes 8 is trapezoidal. The bottom of the ventilation holes 8 is interconnected with the top of the one-way water-locking layer 3. Through the opened trapezoidal ventilation holes 8, water can be better conducted. When the baby urinates, urine can quickly enter the absorbent cotton 71 from the ventilation holes 8. After being absorbed by the absorbent resin 7, the interior is kept dry and ventilation can be carried out through the ventilation holes 8. The ventilation holes 8 can be arranged over a large area.
[0030] Among them, the skin-friendly layer 6 adopts high molecular weight silk peptide, and the thickness of the skin-friendly layer 6 is 0.1-0.15 mm. The silk peptide can provide necessary nutrients for the normal metabolism of the skin and hair, thereby increasing the natural gloss and elasticity of the skin and hair. During long-term use, there is more friction between the human legs and the non-woven fabric. Setting the skin-friendly layer 6 can effectively protect the skin.
[0031] Among them, the antibacterial layer 5 is weakly acidic cotton, and the thickness of the antibacterial layer 5 is 0.2-0.3 mm. The weakly acidic cotton forms a weakly acidic environment, which makes the pH value close to that of human skin, and can reduce irritation to the skin. The weakly acidic environment will inhibit the growth of most bacteria and reduce the internal bacteria to further protect the user's skin.
[0032] Among them, the first non-woven fabric layer 1, the second non-woven fabric layer 2, the one-way water-locking layer 3, the outer layer 4, the antibacterial layer 5, and the skin-friendly layer 6 are arranged from top to bottom as the skin-friendly layer 6, the second non-woven fabric layer 2, the antibacterial layer 5, the first non-woven fabric layer 1, the one-way water-locking layer 3 and the outer layer 4. The outer layer 4 adopts a waterproof and breathable film, which can prevent the moisture of the absorbent cotton from flowing out, and can effectively maintain the effect of internal air circulation.
[0033] The specific usage and function of this embodiment are as follows:
[0034] In the utility model, when the baby uses it, when the baby urinates, the trapezoidal air holes 8 provided can better guide water, and the urine can quickly enter the absorbent cotton 71 from the air holes 8, and then be absorbed by the absorbent resin 7 to keep the interior dry, and ventilation is carried out through the large-area air holes 8, and the moisture is quickly absorbed by the absorbent cotton 71, and then the moisture inside the absorbent cotton 71 is absorbed by the absorbent resin 7. The absorbent resin 7 adopts a one-way water-locking resin, and the moisture is fully absorbed by the one-way water-locking resin to maintain a relatively dry internal environment. The outer layer 4 adopts a waterproof and breathable membrane to prevent the moisture of the absorbent cotton from flowing out, and at the same time can effectively maintain the effect of internal air circulation. The skin-friendly layer 6 adopts a high molecular weight silk peptide, which is smoother when used, and the diaper is more comfortable to use. A weakly acidic environment is formed through the weakly acidic antibacterial layer 5, which makes it close to the pH value of human skin, which can reduce irritation to the skin. The weakly acidic environment will inhibit the growth of most bacteria, and reduce the internal bacteria to further protect the user's skin.
