Description

Technical Field

[0001] This utility model relates to nonwoven fabrics, and more particularly, to a nonwoven fabric structure for body cleaning. Background Technology

[0002] Existing technology, such as Chinese Patent No. CN220535101U, discloses a non-woven fabric with strong cleaning ability. This technical solution involves setting an intermediate layer in the multi-layered structure of the non-woven fabric body, and encapsulating and fixing cleaning balls made of plastic particles within it. These cleaning balls are specifically shaped as cubes or spheres. This design aims to utilize the rigid plastic particles to support the fabric surface, thereby increasing the friction between the non-woven fabric and the skin, achieving a physical exfoliation effect.

[0003] However, this technical solution has significant drawbacks: it relies solely on the physical friction of hard particles for cleaning, lacking necessary cushioning and lubrication. Because the cleaning balls are made of high-hardness plastic, and some particles have a cubic structure with sharp edges, the sharp edges can easily penetrate the thin surface and press or scratch the skin during actual wiping. This harsh feel not only reduces user comfort but also easily scratches the skin's surface when applying force, posing a risk of damaging the skin barrier. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a non-woven fabric structure for body cleaning that is less likely to cause damage to the skin.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a body cleaning non-woven fabric structure, including a first non-woven fabric layer, an adhesive layer fixed on the first non-woven fabric layer, flexible abrasive particles and a capsule containing cleaning oil fixedly connected to the side of the adhesive layer opposite to the first non-woven fabric layer, a second non-woven fabric layer fixed on the side of the adhesive layer opposite to the first non-woven fabric layer, a mesh distributed on the second non-woven fabric layer, and the capsule located in the mesh.

[0006] To achieve the above technical solution, during use, when the non-woven fabric structure for body cleaning is wetted, the flexible abrasive particles remain solid and raised due to their water-insoluble properties. When the user presses the non-woven fabric structure onto the body surface and performs a wiping motion, the normal pressure applied to the surface of the second non-woven fabric layer instantaneously exceeds the yield strength of the capsule shell, causing the capsule to rupture mechanically. The cleaning oil inside the capsule is then released. The released cleaning oil effectively reduces the coefficient of sliding friction between the second non-woven fabric layer and the skin, eliminating dryness and dragging sensations, and preventing damage to healthy epidermis.

[0007] As a preferred embodiment of this utility model, the flexible abrasive particles include elastic TPU particles.

[0008] To achieve the above technical solution, during use, the flexible exfoliating particles, acting as physical cleaning units, maintain a stable physical form without swelling or softening in a humid environment rich in cleansing oil and moisture. When the flexible exfoliating particles glide across the skin surface, they undergo instantaneous compliant deformation upon encountering tiny skin protrusions, rather than rigidly cutting. This prevents scratching the dermis due to excessive local pressure, further enhancing the safety of the cleansing process.

[0009] As a preferred embodiment of this utility model, the aperture of the mesh is smaller than the outer diameter of the flexible abrasive particles.

[0010] To achieve the above technical solution, during the wiping process, because the mesh size of the second non-woven fabric layer is designed to be smaller than the outer diameter of the flexible abrasive particles and the particle size of the capsules, these flexible abrasive particles are physically locked in the cavity limiting structure formed by the first and second non-woven fabric layers in three-dimensional space. Utilizing the principle of small holes holding large balls, this prevents the flexible abrasive particles and capsules from becoming slippery and falling off the mesh in a cleaning oil-lubricated environment.

[0011] As a preferred embodiment of this utility model, the side of the first nonwoven fabric layer facing away from the adhesive layer is laminated with a waterproof membrane layer.

[0012] To achieve the above technical solution, as the capsule ruptures and releases the cleaning oil, the impermeable membrane layer on the back of the first non-woven fabric layer blocks the penetration path of the cleaning oil towards the palm. This impermeable membrane layer effectively blocks the cleaning oil, ensuring that the cleaning oil and dirt only act on one side of the skin, preventing contamination of the user's hands.

[0013] In a preferred embodiment of this invention, the geomembrane layer comprises a TPU film.

[0014] To achieve the above technical solution, the TPU film used as the geomembrane layer has excellent low-temperature flexibility and high elongation at break, and can be bent and stretched synchronously with the first nonwoven fabric layer without plastic deformation.

[0015] As a preferred embodiment of this utility model, a hand strap is provided on the side of the geomembrane layer opposite to the first nonwoven fabric layer, and the two ends of the hand strap are fixed to the geomembrane layer.

[0016] To achieve the above technical solution, during use, especially when the release of cleaning oil reduces overall friction and the environment becomes slippery, the user inserts their palm into the handheld strap. The handheld strap forms a reverse mechanical restraint on the back of the user's hand, anchoring the non-woven fabric cleaning structure to the palm. This allows the user to apply stable force and precisely control the wiping trajectory, ensuring the continuity of the cleaning process.

[0017] As a preferred embodiment of the present invention, the edges of the first nonwoven fabric layer and the second nonwoven fabric layer are fixedly connected to a binding layer, which wraps the edges of the first nonwoven fabric layer and the second nonwoven fabric layer inside the binding layer.

[0018] To achieve the above technical solution, with the body-cleaning nonwoven fabric structure filled with fluid cleaning oil, the edge-sealing layer tightly wraps the open edges of the first and second nonwoven fabric layers in a U-shaped structure, blocking the channels for liquid to diffuse laterally along the fiber capillaries. The edge-sealing layer effectively prevents the cleaning oil, after cell wall disruption, from leaking out from the sides, forcing the cleaning oil to concentrate in the central mesh area to exert its effect.

[0019] In a preferred embodiment of the present invention, the edge-binding layer includes a coated nonwoven fabric layer, wherein the coated nonwoven fabric layer faces the first nonwoven fabric layer and the second nonwoven fabric layer.

[0020] To achieve the above technical solution, during the manufacturing stage, the inward-facing nonwoven fabric layer is heated and melted, penetrating into the fiber gaps between the first and second nonwoven fabric layers, and forming an integrated connection after cooling. This film layer acts as a dense barrier medium. Utilizing the self-adhesive and anti-permeability properties of the thermoplastic film layer, high-strength fusion bonding between the edge layer and the main body can be achieved without additional adhesives; simultaneously, the inward-facing film layer constructs a lateral anti-seepage wall, completely eliminating the risk of cleaning oil seeping to the edges through capillary action, ensuring excellent side-leakage prevention performance.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0024] A nonwoven fabric structure for body cleaning includes a first nonwoven layer 1, with a geomembrane layer 2 laminated to the side opposite to the adhesive layer 4. The geomembrane layer 2 is made of TPU film, utilizing the excellent elasticity and density of TPU to create a physical barrier that effectively prevents the backflow of oil-water mixtures generated during cleaning. To improve grip stability, a hand strap 3 is provided on the outside of the geomembrane layer 2. The two ends of the hand strap 3 are firmly fixed to the geomembrane layer 2, forming a grip structure that allows the palm to pass through. The hand strap 3 is made of nonwoven fabric.

[0025] An adhesive layer 4, made of acrylic pressure-sensitive adhesive, is fixed to the side of the first nonwoven layer 1 facing away from the geomembrane layer 2. This adhesive layer 4 serves as a carrier, with a mixture of flexible abrasive particles 5 and capsules 7 fixedly attached to its surface. The capsules 7 are alginate capsules containing cleaning oil 6. The flexible abrasive particles 5 are made of elastic TPU particles, possessing low hardness and high resilience to provide gentle physical friction. The shell of the alginate capsule 7 is made of alginate gel, encapsulating an anhydrous cleaning oil 6. The cleaning oil 6 is either bath oil or emulsified makeup remover. Covering the adhesive layer 4 is a second nonwoven layer 8, made of spunlace nonwoven fabric with several through-mesh 9s.

[0026] The alginate capsule 7 is designed with a particle size smaller than the mesh size 9 of the second nonwoven fabric layer 8, so that the alginate capsule 7 can fall completely into and be contained in the mesh size 9, thus being fully exposed on the outer surface to ensure direct contact and release with the skin; while the outer diameter of the flexible abrasive particles 5 is larger than the mesh size 9, so that the flexible abrasive particles 5 are pressed and locked by the fiber skeleton of the second nonwoven fabric layer 8, forming a semi-enclosed protruding structure, which not only prevents the particles from falling off, but also provides a stable abrasive feel.

[0027] To prevent edge leakage, an edge binding layer 10 is fixedly connected to the edges of the first nonwoven fabric layer 1 and the second nonwoven fabric layer 8. The edge binding layer 10 has a U-shaped cross-section, which completely wraps the cut edges of the first nonwoven fabric layer 1, the adhesive layer 4 and the second nonwoven fabric layer 8 within the internal cavity of the edge binding layer 10.

[0028] The edge-binding layer 10 is made of coated nonwoven fabric, with the coated layer 11 facing inward, that is, directly bonded to the surfaces of the first nonwoven fabric layer 1 and the second nonwoven fabric layer 8. It is connected to the first nonwoven fabric layer 1 and the second nonwoven fabric layer 8 by melting and fixing the coated layer 11. The coated layer 11 on the coated nonwoven fabric layer is a PE coated layer 11.

[0029] The production process is as follows: First, a TPU film is laminated to the back of the first nonwoven fabric layer 1. Next, at room temperature, an acrylic pressure-sensitive adhesive is evenly coated on the front of the first nonwoven fabric layer 1, and a mixture of flexible abrasive particles 5 and alginate capsules 7 is spread. Then, a perforated second nonwoven fabric layer 8 is placed on top, and the alginate capsules 7 are smoothly inserted into the mesh 9 by the rolling action of a flexible rubber roller. Simultaneously, the flexible abrasive particles 5 are locked in place by the fibers surrounding the mesh 9, and the acrylic pressure-sensitive adhesive completes the strong bonding of the three-layer structure.

[0030] Then, edge processing is carried out. A coated nonwoven fabric layer is used as the edge covering layer 10. It is folded into a U-shape to wrap the edges of the first nonwoven fabric layer 1 and the second nonwoven fabric layer 8, and the coated layer 11 of the coated nonwoven fabric layer is made to face inward. The coated layer 11 is melted and sealed to the side by local hot pressing to prevent side leakage, thereby obtaining the finished product.

[0031] Finally, the hand strap 3 is glued to the geomembrane layer 2.

[0032] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
