Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and more specifically to a breathable non-woven adhesive tape. Background Technology

[0002] Adhesive tape is used to attach dressings to wounds or to attach other medical devices to specific parts of the body. It is a commonly used product in medical and daily care fields.

[0003] Traditional adhesive tape often suffers from poor breathability. When used for wound bandaging or fixing dressings, non-breathable tape may cause the skin to feel hot and damp, leading to adverse reactions such as skin allergies and itching, which can affect the wound healing process. This is especially problematic for patients who need to use tape for extended periods of time. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a breathable non-woven tape to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a breathable non-woven tape, including a tape body, the tape body including a non-woven fabric layer, the bottom of the non-woven fabric layer being coated with an adhesive layer, the upper surface of the non-woven fabric layer having a plurality of air vents, and the outer side of each of the plurality of air vents having an integrally formed connecting edge hole, and the adhesive layer having a through hole communicating with the air vents and the connecting edge hole at a position below the air vents and the connecting edge hole.

[0006] As a further improvement of this utility model, each of the multiple vent holes and connecting edge holes is melt-blown with a filter screen to filter external dust.

[0007] As a further embodiment of this invention, the vent holes and the plurality of connecting edge holes are combined to form a cross shape.

[0008] As a further embodiment of this utility model, the upper surface of the nonwoven fabric layer is embossed with indentations on both sides.

[0009] As a further embodiment of this invention, the length of the indentation is equal to the length of the nonwoven fabric layer.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model features breathable holes and connecting edge holes. The nonwoven fabric is made by melting, extruding, and stretching a polymer to form continuous filaments, which are then laid on a web-forming machine to form a fiber web. The fibers in the web are then entangled and reinforced through hot rolling and needle punching, ultimately forming a breathable nonwoven fabric. This gives the nonwoven fabric itself good breathability. Furthermore, the nonwoven tape has multiple breathable holes and connecting edge holes, and no adhesive layer is coated below these holes. This allows gas to circulate within the breathable holes and connecting edge holes, coming into contact with the skin. This improves the breathability of the nonwoven tape, solving the problem of non-breathable tape causing stuffiness and dampness on the skin, leading to skin allergies, itching, and other adverse reactions, thus affecting wound healing.

[0012] 2. This utility model incorporates a filter screen, which is manufactured using a melt-blown process within the ventilation holes and connecting edge holes. This filter screen filters the gas passing through the ventilation holes and connecting edge holes, thereby removing dust and impurities from the gas and preventing them from coming into contact with the wound.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Reference Figures 1-3This utility model provides a breathable nonwoven tape, including a tape body 1, which includes a nonwoven fabric layer 3. The bottom of the nonwoven fabric layer 3 is coated with an adhesive layer 2. Multiple air vents 5 are formed on the upper surface of the nonwoven fabric layer 3. Connecting edge holes 6 are integrally formed on the outer sides of each of the multiple air vents 5. The adhesive layer 2 has through holes below the air vents 5 and connecting edge holes 6, communicating with them. The polymer is melted, extruded, and stretched to form continuous filaments. These filaments are then laid on a web forming machine to form a fiber web. The fibers in the fiber web are then entangled and reinforced through hot rolling, needle punching, and other methods. A breathable nonwoven fabric layer 3 is formed. Then, a laser punching machine is used to punch multiple evenly distributed air holes 5 on the nonwoven fabric layer 3, and multiple connecting edge holes 6 are punched on the outside of the multiple air holes 5. Subsequently, an adhesive layer is applied to the nonwoven fabric layer 3 using a coating machine, and the adhesive layer located at the air holes 5 and connecting edge holes 6 is cleaned out to form through holes. During the use of the nonwoven tape, gas will circulate in the air holes 5 and connecting edge holes 6 and come into contact with the skin, thereby giving the nonwoven tape a better breathability effect. This solves the problem that non-breathable tape causes the skin to feel stuffy and damp, which in turn causes adverse reactions such as skin allergies and itching, and affects the wound healing process.

[0019] In this invention, multiple vent holes 5 and connecting edge holes 6 are filled with melt-blown filter screens 7 for filtering external dust. The vent holes 5 and multiple connecting edge holes 6 are combined to form a cross shape. The filter screens 7 are made in the vent holes 5 and connecting edge holes 6 through a melt-blowing process. At this time, the filter screens 7 will filter the gas passing through the vent holes 5 and connecting edge holes 6, thereby removing dust and impurities in the gas and preventing dust and impurities from contacting the wound. The upper surface of the non-woven fabric layer 3 is embossed with indentations 4 on both sides. The length of the indentations 4 is equal to the length of the non-woven fabric layer 3. By pressing the indentations 4 on the surface of the non-woven fabric layer 3 using an embossing process, the flatness of the non-woven fabric layer 3 can be guaranteed.

[0020] The working principle of this invention is as follows: In use, a polymer is melted, extruded, and stretched to form continuous filaments. These filaments are then laid on a web-forming machine to form a fiber web. The fibers in the web are then entangled and reinforced through hot rolling and needle punching, ultimately forming a breathable nonwoven fabric layer 3. A laser punching machine is then used to punch multiple evenly distributed air holes 5 on the nonwoven fabric layer 3, and multiple connecting edge holes 6 are punched on the outer side of the air holes 5. Finally, an adhesive layer is applied to the nonwoven fabric layer 3 using a coating machine. The adhesive layer at the vent hole 5 and the connecting edge hole 6 is cleaned out to form through holes. Then, a filter 7 is made in the vent hole 5 and the connecting edge hole 6 using a melt-blowing process, thus forming a non-woven tape. During the use of the non-woven tape, gas will circulate in the vent hole 5 and the connecting edge hole 6 and come into contact with the skin, thereby giving the non-woven tape a better breathability. This solves the problem that non-breathable tape causes the skin to feel stuffy and damp, which in turn causes adverse reactions such as skin allergies and itching, and affects the wound healing process.
