Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to an antibacterial and breathable nonwoven fabric. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is a type of fabric made from pressed fibers without being woven. It is commonly used in hygiene products such as diapers and sanitary napkins. Non-woven fabrics used in hygiene products typically need to have certain antibacterial properties to prevent users from being infected by bacteria and affecting their health. However, some non-woven fabrics currently have poor breathability. When used in hygiene products, this can lead to poor breathability, causing users to feel stuffy and sweat excessively. Sweat adhering to the skin creates an environment conducive to bacterial growth. If the non-woven fabric is completely in close contact with the skin, it exacerbates the stuffiness and continues to produce excessive sweat. If the non-woven fabric cannot adhere closely to the skin, its antibacterial properties are difficult to apply, leading to potential health risks for users when using these hygiene products.

[0003] Based on the above, Chinese patent document CN108248168A discloses an antibacterial nonwoven fabric, including a spunbond nonwoven fabric layer, a first antibacterial nonwoven fabric layer, a second antibacterial nonwoven fabric layer, and a viscose nonwoven fabric layer. The first antibacterial nonwoven fabric layer and the second antibacterial nonwoven fabric layer are located between the anti-adhesive nonwoven fabric layer and the viscose nonwoven fabric layer. The first antibacterial nonwoven fabric layer is located above the second antibacterial nonwoven fabric layer. A meltblown nonwoven fabric layer is also provided between the first antibacterial nonwoven fabric layer and the second antibacterial nonwoven fabric layer.

[0004] The aforementioned patent document discloses a nonwoven fabric with antibacterial function. Both the first and second antibacterial nonwoven layers of this nonwoven fabric contain antibacterial components with long-term antibacterial effects, enabling the nonwoven fabric to maintain stable antibacterial properties over a long period. However, because this nonwoven fabric is composed of multiple layers of composite materials, its thickness affects its breathability. During use, the nonwoven fabric easily leads to the production of a large amount of sweat by the human body. If bacteria multiply in large quantities on the surface of the human body through sweat, it can easily affect the user's health. Based on the defect of poor breathability of this nonwoven fabric, it can be seen that there is still room for improvement. Utility Model Content

[0005] To address the technical deficiencies in the background technology, this utility model proposes an antibacterial and breathable nonwoven fabric, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0006] An antibacterial and breathable nonwoven fabric includes a nonwoven fabric body and an antibacterial layer. The nonwoven fabric body is formed with a flow-guiding and diffusion zone, a permeation zone and a flow-guiding and diffusion zone in sequence along the width direction. The upper surface of the nonwoven fabric body is provided with a plurality of permeation holes and a plurality of first protrusions in the permeation zone. Each first protrusion has four permeation holes distributed on its edge.

[0007] The upper surface of the nonwoven fabric body is provided with several flow-guiding grooves in the flow-guiding and diffusion area. The several flow-guiding grooves distributed along the length direction are connected in sequence and together form the first diffusion groove.

[0008] The lower surface of the nonwoven fabric body is provided with a plurality of embedded grooves that match the first protrusion, the embedded grooves are provided with antibacterial slow-release beads, and the antibacterial layer covers the lower surface of the nonwoven fabric body.

[0009] As a further technical solution of this utility model, a group of permeable holes distributed along the same straight line in the width direction forms a group of permeable holes. The permeable zone is provided with a group of permeable holes distributed along the length direction, and the permeable holes in two adjacent groups of permeable holes are staggered in the length direction.

[0010] As a further technical solution of this utility model, the shape of the flow guiding groove is square or rhomboid, and each flow guiding groove has a flow guiding hole at the bottom that extends to the bottom of the non-woven fabric body. Each flow guiding groove has four flow guiding holes, which are respectively distributed at the corners of the flow guiding groove.

[0011] As a further technical solution of this utility model, the upper surface of the nonwoven fabric body is provided with a number of second protrusions in the flow diffusion area, and each second protrusion has four flow grooves distributed on its edge.

[0012] As a further technical solution of this utility model, the upper surface of the nonwoven fabric body is provided with a second diffusion groove extending along the length direction between the flow diffusion zone and the penetration zone.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model discloses a nonwoven fabric that combines antibacterial and breathable properties. This nonwoven fabric is mainly used as the surface layer of hygiene products such as diapers and sanitary napkins. The nonwoven fabric promotes rapid downward penetration of liquid through its permeation zone and promotes large-area diffusion of liquid while simultaneously permeating downwards through its diffusing zone, preventing liquid from stagnating inside the nonwoven fabric for extended periods. The combination of permeation and diffusing pores gives the nonwoven fabric excellent breathability, preventing users from experiencing stuffiness or sweating during use. This creates an environment unfavorable to bacterial growth between the nonwoven fabric and the human body. Combined with the antibacterial function of antibacterial slow-release beads and the antibacterial layer, the nonwoven fabric exhibits even superior antibacterial properties.

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] An antibacterial and breathable nonwoven fabric includes a nonwoven fabric body 1 and an antibacterial layer 2. The nonwoven fabric body 1 is formed with a flow-guiding and diffusion zone 11, a permeation zone 12 and a flow-guiding and diffusion zone 11 in sequence along the width direction. The upper surface of the nonwoven fabric body 1 is provided with a plurality of permeation holes 121 and a plurality of first protrusions 122 in the permeation zone 12. Each first protrusion 122 has four permeation holes 121 distributed on its edge.

[0022] The upper surface of the nonwoven fabric body 1 is provided with a plurality of flow-guiding grooves 111 in the flow-guiding and diffusion area 11. The plurality of flow-guiding grooves 111 distributed along the length direction are connected in sequence and together form the first diffusion groove 112.

[0023] The lower surface of the nonwoven fabric body 1 is provided with a plurality of embedding grooves 13 that match the first protrusion 122. The embedding grooves 13 are provided with antibacterial slow-release beads 14, and the antibacterial layer 2 covers the lower surface of the nonwoven fabric body 1.

[0024] This utility model discloses a nonwoven fabric that combines antibacterial and breathable properties. This nonwoven fabric is mainly used as the surface layer of hygiene products such as diapers and sanitary napkins. When used as the surface layer of hygiene products, this nonwoven fabric refers to… Figure 1 , Figure 2 , Figure 3 , Figure 4 The upper surface of the nonwoven fabric body 1, facing the human body, has a permeation zone 12 formed in the center of the nonwoven fabric body 1 along the width direction to promote the downward permeation of liquid. When the user uses the sanitary product, the urine or blood excreted by the user will first flow into the permeation zone 12, and the permeation holes 121 in the permeation zone 12 can promote the rapid downward permeation of these liquids and be absorbed by the absorbent core inside the sanitary product. In addition, the two sides of the nonwoven fabric body 1 along the width direction have a flow-guiding and diffusion zone 11 for guiding the liquid to spread over a wider area. When the user uses the sanitary product, when urine or blood flows into the flow-guiding and diffusion zone 11, the flow-guiding groove 111 can accommodate these liquids and also allow these liquids to spread along the length direction along the first diffusion groove 112. The flow-guiding and diffusion zone 11 can limit the liquid from continuing to flow along the width direction, which is beneficial to improving the side leakage prevention effect of the sanitary product.

[0025] In the permeation zone 12, the nonwoven fabric body 1 is processed by a perforation process commonly used in nonwoven fabrics to form a number of permeation holes 121. A groove is formed on the upper surface of the nonwoven fabric body 1 at the location where each permeation hole 121 is formed. There is a certain distance between adjacent permeation holes 121. The groove formed by the four permeation holes 121 will form a quadrilateral protrusion structure between these four permeation holes 121. This protrusion structure is the first protrusion 122. The fibers in the nonwoven fabric body 1 are stacked at the location of each first protrusion 122 to form a certain thickness. The fibers with a certain thickness at the first protrusion 122 are mainly for better embedding the antibacterial slow-release beads 14 into the interior of the nonwoven fabric body 1.

[0026] When embedding the antibacterial slow-release beads 14 into the nonwoven fabric body 1, the lower surface of the nonwoven fabric body 1 is processed by dot-matrix hot pressing to form embedding grooves 13 at the bottom of the nonwoven fabric body 1 relative to the first protrusion 122. Then, the antibacterial slow-release beads 14 are placed inside the embedding grooves 13. The antibacterial slow-release beads 14 are spherical materials containing common antibacterial agents that slowly dissolve in water. When the nonwoven fabric body 1 comes into contact with a liquid, the antibacterial slow-release beads 14 slowly release the antibacterial components, giving the nonwoven fabric body 1 antibacterial function. The antibacterial layer 2 is composed of antibacterial materials containing common antibacterial agents. The antibacterial coating is formed after curing. After the antibacterial slow-release beads 14 are placed inside the embedding groove 13, an antibacterial coating is applied to the lower surface of the nonwoven fabric body 1. During the process of the antibacterial coating curing to form the antibacterial layer 2 on the lower surface of the nonwoven fabric body 1, the antibacterial coating adheres and fixes the antibacterial slow-release beads 14 to the inside of the embedding groove 13 through its adhesive force, preventing the antibacterial slow-release beads 14 from falling off from the nonwoven fabric body 1. The antibacterial layer 2 completely covers the lower surface of the nonwoven fabric body 1. When the nonwoven fabric body 1 is used as the surface layer of the sanitary product, the antibacterial layer 2 can exert its antibacterial ability evenly inside the sanitary product.

[0027] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 A group of permeable holes 121 distributed along the same straight line in the width direction forms a group of permeable holes. The permeable zone 12 is provided with a group of permeable holes distributed along the length direction. The permeable holes 121 in two adjacent groups of permeable holes are staggered in the length direction. When the liquid flows along the upper surface of the nonwoven fabric body 1 in the permeable zone 12, it usually flows along the upper surface of the first protrusion 122. When the liquid flows to the permeable hole 121, it will flow downward along the permeable hole 121 under the action of capillary effect. When the permeable holes 121 in the permeable zone 12 are distributed in the above manner, the direction of the adjacent first protrusions 122 is inclined. Then the liquid is difficult to continuously flow along the width or length direction in the permeable zone 12, making it easier for the liquid to contact the permeable hole 121 and penetrate downward during the flow process. This prevents the liquid from flowing along the upper surface of the nonwoven fabric body 1 to the outside of the nonwoven fabric body 1. When the sanitary products use the nonwoven fabric of this utility model as the surface layer, they can have better anti-leakage performance.

[0028] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 The flow-guiding groove 111 is square or rhomboid in shape. Each flow-guiding groove 111 has a flow-guiding hole 113 at the bottom that extends to the bottom of the nonwoven fabric body 1. There are four flow-guiding holes 113 in each flow-guiding groove 111, which are distributed at the corners of the flow-guiding groove 111. The shape of the flow-guiding groove 111 is preferably rhomboid, and the two diagonals of the rhomboid extend along the width direction and the length direction, respectively. With this structure, since the width of the two ends of the flow-guiding groove 111 along the length direction is small, the liquid will be partially intercepted at the wider central position of the flow-guiding groove 111 during the flow along the first diffusion groove 112. The intercepted liquid can quickly penetrate downward through the flow-guiding hole 113, while the uninterrupted liquid will continue to diffuse along the adjacent flow-guiding groove 111. The above structure allows the liquid to diffuse over a wide area and penetrate downward efficiently in the flow-guiding diffusion area 11.

[0029] Furthermore, both the permeation pore 121 and the flow guiding pore 113 can promote the rapid downward penetration of liquid. When the non-woven fabric of this invention is used as the surface layer of the sanitary product, the liquid can quickly penetrate into the interior of the sanitary product and be absorbed by the absorbent core, avoiding the liquid from lingering in the surface layer for a long time, which is beneficial to improving the dryness of the surface layer. When the interior of the surface layer is kept dry, its internal fiber structure can allow more air to pass through. The combination of the two pore structures, the permeation pore 121 and the flow guiding pore 113, makes the sanitary product have good breathability. Users are less likely to feel stuffy or sweaty during the use of the sanitary product, which creates an environment unfavorable to bacterial growth between the sanitary product and the human body. Combined with the antibacterial function of the antibacterial slow-release beads 14 and the antibacterial layer 2, the sanitary product can have even better antibacterial performance.

[0030] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 4 The upper surface of the nonwoven fabric body 1 has several second protrusions 114 in the flow-guiding and diffusion area 11. Each second protrusion 114 has four flow-guiding grooves 111 distributed on its edge. The several second protrusions 114 are connected sequentially along the length direction and form a protrusion structure extending along the length direction on both sides of the first diffusion groove 112. This allows the first diffusion groove 112 to contain a certain amount of liquid and allow the liquid to flow along the first diffusion groove 112. Since the shape of the flow-guiding groove 111 is rhomboid, the shape of the second protrusions 114 is also rhomboid, causing the width of the protrusion structure to change periodically. In areas where the thickness of the protrusion structure is low, the liquid in one of the first diffusion grooves 112 can penetrate or flow into the adjacent first diffusion grooves 112, allowing the liquid to flow along multiple first diffusion grooves 112 simultaneously, which is beneficial to improving the efficiency of the flow-guiding and diffusion area 11 in promoting liquid diffusion.

[0031] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 The upper surface of the nonwoven fabric body 1 is provided with a second diffusion groove 15 extending along the length direction between the flow-guiding diffusion zone 11 and the permeation zone 12. When the liquid flows along the width direction in the permeation zone 12 to the edge of the permeation zone 12, the liquid will enter the second diffusion groove 15 and be partially intercepted, reducing the speed of the liquid flow along the width direction. The second diffusion groove 15 can promote the diffusion of the liquid along the length direction, which is beneficial to improving the uniformity of the liquid distribution in the nonwoven fabric body 1. When the nonwoven fabric of this utility model is used as the surface layer of the sanitary product, the liquid can be evenly distributed inside the sanitary product and absorbed by the absorbent core, which is beneficial to improving the absorption efficiency of the sanitary product.

[0032] In summary, this utility model discloses a nonwoven fabric that combines antibacterial and breathable properties. This nonwoven fabric is mainly used as the surface layer of hygiene products such as diapers and sanitary napkins. The nonwoven fabric promotes rapid downward penetration of liquid through the permeation zone 12 and promotes large-area diffusion of liquid while permeating downward through the diffusing zone 11, avoiding prolonged stagnation of liquid inside the nonwoven fabric. The combination of the two pore structures, permeation pore 121 and diffusing pore 113, gives the nonwoven fabric good breathability. Users are less likely to experience stuffiness or sweating during use, creating an environment unfavorable to bacterial growth between the nonwoven fabric and the human body. Combined with the antibacterial function of the antibacterial slow-release beads 14 and the antibacterial layer 2, the nonwoven fabric can have even better antibacterial properties.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
