Description

Technical Field

[0001] This utility model relates to the field of wet wipes technology, specifically to a wet wipe with long-lasting water-locking and moisturizing function. Background Technology

[0002] Moisturizing wipes are widely used, and as people pay more attention to skin care, the requirements for the moisturizing performance of wipes are also higher. Currently, most wipes on the market achieve their moisturizing effect by adding moisturizing agents, but these agents are prone to evaporation or loss, making it difficult to achieve long-lasting hydration.

[0003] CN212375493U discloses a liquid-absorbing and moisturizing baby wipe base fabric, which consists of three layers: microfiber layer I, liquid-absorbing fiber layer, and microfiber layer II, wherein microfiber layer I and microfiber layer II are made of polypropylene.

[0004] However, it relies solely on the middle absorbent fiber layer to perform the main absorbent and some water-locking functions, while the polypropylene microfiber layers on both sides have poor hygroscopicity, which easily leads to moisture loss from the base fabric and contributes little to water locking. Therefore, it is difficult to achieve long-lasting water-locking and moisturizing.

[0005] Based on this, the present invention designs a wet wipe with long-lasting water-locking and moisturizing function to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a wet wipe with long-lasting water-locking and moisturizing function.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wet wipe with long-lasting water-locking and moisturizing function includes, from top to bottom, a skin-friendly layer (A side), a water-permeable layer (A side), a cellulose sponge layer (A side), a middle water-retaining layer, a cellulose sponge layer (B side), a water-permeable layer (B side), and a skin-friendly layer (B side). The water-permeable layers A and B sides each have a first wave-shaped section formed by heat pressing on their opposing sides. The cellulose sponge layers A and B sides each have a second wave-shaped section formed by heat pressing on their opposing sides. The first and second wave-shaped sections are connected in a concave-convex manner.

[0009] Furthermore, the skin-friendly layers on side A and side B are made of cotton fibers through hydroentangling.

[0010] Furthermore, the A-side permeable layer and the B-side permeable layer are made of hemp fiber through hydroentangling.

[0011] Furthermore, the A-side cellulose sponge layer and the B-side cellulose sponge layer are made of wood cellulose sponge or bamboo cellulose sponge with a porous structure.

[0012] Furthermore, the central water-retaining layer is woven from seaweed fibers.

[0013] Furthermore, the height of the first wave section is one-third of the height of the permeable layer on side A and side B.

[0014] Furthermore, the height of the second wave section is half the height of the A-side cellulose sponge layer and the B-side cellulose sponge layer.

[0015] Furthermore, the height of the first wave section is the same as the height of the second wave section.

[0016] Furthermore, the skin-friendly layer A, the water-permeable layer A, the cellulose sponge layer A, the middle water-retaining layer, the cellulose sponge layer B, the water-permeable layer B, and the skin-friendly layer B are bonded together with hot melt adhesive.

[0017] Furthermore, the thickness of the skin-friendly layer on side A and the skin-friendly layer on side B is 0.5~0.8 mm;

[0018] The thickness of the permeable layer on side A and the permeable layer on side B is 0.6~0.9 mm;

[0019] The thickness of the cellulose sponge layer on side A and the cellulose sponge layer on side B is 0.4~0.6 mm;

[0020] The thickness of the central water-retaining layer is 0.8~1.2 mm.

[0021] Compared to existing technologies, this invention offers the following advantages: It achieves efficient water retention through a central water-retaining layer, good water absorption through cellulose sponge layers on sides A and B, water permeability to both sides through permeable layers on sides A and B, and skin-friendly contact with the skin through skin-friendly layers on sides A and B. This invention possesses excellent liquid absorption and water-locking functions, preventing moisture loss and providing long-lasting hydration. It is also highly comfortable to use and more suitable for people with sensitive skin. The design of the first and second wave sections with their matching concave-convex connections facilitates water dispensing during use and timely water retention upon stopping pressure, reducing moisture loss.
