Description

Technical Field

[0001] This utility model relates to the field of diaper technology, specifically a novel online composite ultra-breathable diaper. Background Technology

[0002] Disposable diapers are single-use products. Currently, the waterproof and breathable materials used in diapers on the market are mainly PE breathable films. However, PE breathable films are only slightly breathable or even not breathable at all. When a baby's urine comes into contact with the diaper, heat cannot pass through in time. In this humid and stuffy microenvironment, babies may experience allergies, diaper rash, and other problems. Therefore, there is an urgent need to improve the waterproof and breathable structure of diapers to enhance their breathability. Utility Model Content

[0003] The purpose of this invention is to provide a novel online composite ultra-breathable diaper to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel online composite ultra-breathable diaper includes an outer bottom layer, a PE film, a core, and a top layer. The bottom film is bonded to the outer bottom layer. The core is located between the PE film and the top layer. The PE film has a perforated area in the middle, and several air vents are formed in the perforated area. The perforated area is bonded to an ultra-breathable material layer, which is located between the PE film and the core.

[0006] In one possible implementation, the ultra-permeable material layer is a composite membrane made of PTFE membrane and single or multiple layers of spunbond nonwoven fabric.

[0007] In one possible implementation, the outer bottom layer or the top layer is made of hot-air nonwoven fabric, and the basis weight of the hot-air nonwoven fabric is not less than 16 g / m².

[0008] In one possible implementation, the basis weight of the ultra-permeable material layer is 10-50 g / m², and the basis weight of the PE film is 10-20 g / m².

[0009] In one possible implementation, the perforated area is bonded to the ultra-permeable material layer by ultrasonic welding or hot melt adhesive.

[0010] In one possible implementation, the vent holes are arranged in an array.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] By layering a breathable PE membrane with an ultra-breathable material layer and punching holes at corresponding positions on the PE membrane and the ultra-breathable material layer to form air pores, the breathability of diapers is greatly improved, while ensuring cost control and enhancing the feasibility of online composite technology.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figure 1 and 2 As shown, a novel online composite ultra-breathable diaper includes an outer bottom layer 2, a PE film 1, a core 6, and a top layer 5. The PE film 1 is bonded to the outer bottom layer 2. The core 6 is located between the PE film 1 and the top layer 5. A perforated area is provided in the middle of the PE film 1, and several breathable holes 3 are formed in the perforated area. The perforated area is bonded to an ultra-breathable material layer 4, which is located between the PE film 1 and the core 6. The ultra-breathable material layer 4 is a composite film made of PTFE film and single or multiple layers of spunbond nonwoven fabric. The outer bottom layer 2 or the top layer 5 is made of hot-air nonwoven fabric with a basis weight of not less than 16 g / m². The basis weight of the ultra-breathable material layer is 10-50 g / m², and the basis weight of the PE film 1 is 10-20 g / m². The perforated area and the ultra-breathable material layer 42 are bonded by ultrasonic welding or hot melt adhesive. The breathable holes 3 are arranged in an array. In this invention, the PE film is larger than the ultra-breathable material layer 4. By perforating the PE film in the middle to form several air vents, the ultra-breathable material layer with waterproof properties is made more breathable. Heat inside the diaper is dissipated to the outside more quickly, thereby improving the diaper's breathability and making it more comfortable to wear. At the same time, since perforations are only made in the perforated areas, the mechanical strength of the PE film is maintained while reducing online processing costs. In this invention, the air vents can be circular, square, or irregularly shaped; the specific shape and size of the vents are not particularly limited.

[0017] The diaper of this invention adopts the following steps: First, a PE film to be processed is perforated to form breathable holes using a special-shaped cutter. Then, a super-breathable material layer composed of a PTFE film and single or multiple layers of spunbond nonwoven fabric (SMS) is bonded to the perforated area containing the breathable holes using adhesive bonding or ultrasonic welding to form a waterproof and breathable composite membrane. Finally, the prepared waterproof and breathable composite membrane is bonded to the outer bottom layer 2, core 6, and top layer 5 sequentially using adhesive bonding or ultrasonic welding to complete the manufacturing process. All of the above operations are carried out on a single production line, enabling online processing.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
