Description

Technical Field

[0001] The present invention relates to the technical field of sanitary products, and in particular to a sanitary napkin contact layer using Ecocotyl fibers and a manufacturing process thereof. Background Art

[0002] As people's living standards improve, higher requirements are placed on the quality and user experience of sanitary napkins. The contact layer of traditional sanitary napkins has certain limitations in terms of absorption performance, breathability, and comfort.

[0003] 1. Poor air permeability: The air permeability of traditional non-woven fabrics is only 2000g / m 2 / 24h, causing stuffiness;

[0004] 2. Low liquid absorption efficiency: liquid absorption time ≥ 5 seconds, which can easily cause surface retention;

[0005] 3. Chemical residue sensitization: Adhesives, fluorescent agents and other additives cause allergy rates as high as 3%-5%.

[0006] Therefore, a sanitary napkin contact layer using Ecocotyl fiber and a manufacturing process thereof have become problems that need to be solved urgently. Summary of the Invention

[0007] The purpose of the present invention is to provide a sanitary napkin contact layer using Eucosil fiber and its production process, so as to solve the problems of poor absorption performance, insufficient air permeability and poor comfort of the existing sanitary napkin contact layer, and improve the overall performance and user experience of the sanitary napkin.

[0008] To achieve the above-mentioned object, the present invention provides a technical solution as follows: a sanitary napkin contact layer using EcoCosy fiber, comprising an EcoCosy fiber layer, a surface layer and a bottom layer;

[0009] The surface of the EcoCosy fiber layer is provided with a three-dimensional concave-convex diversion texture, the surface layer is attached to the surface of the EcoCosy fiber layer and has breathable micropores, and the bottom layer is arranged at the bottom of the EcoCosy fiber layer and is ultrasonically welded to the sanitary napkin.

[0010] Furthermore, the diameter of the Eucosil fiber layer is 0.8D and the weight is 18g / m 2 .

[0011] Furthermore, the pore size of the air-permeable micropores is 5-10 μm.

[0012] The present invention also provides a process for manufacturing a sanitary napkin contact layer using EcoCosy fibers, comprising the following steps:

[0013] S1, Eco-Cosy fiber layer: 100% Eco-Cosy fiber, with a three-dimensional concave and convex flow-guiding texture formed through a hot air penetration process;

[0014] S2. Surface treatment: plasma treatment is used to generate a microporous structure on the surface of the Eucosil fiber layer;

[0015] S3. Bottom layer bonding: Use ultrasonic welding technology to weld the Eucosil fiber layer onto the sanitary napkin.

[0016] The advantages of this invention over existing technologies are as follows: It uses Eco-Cosme fiber as the primary material for the contact layer of the sanitary napkin. Eco-Cosme fiber itself is soft, skin-friendly, and naturally antibacterial, providing a comfortable user experience. The three-dimensional, concave and convex flow-guiding texture on the surface of the Eco-Cosme fiber layer in the contact layer accelerates liquid diffusion and absorption, reduces surface liquid residue, and maintains a dry surface. The breathable micropores in the surface layer ensure good air circulation, reducing stuffiness and the environment conducive to bacterial growth. Furthermore, a specific manufacturing process ensures the quality and performance of each layer, tightly integrating the contact layer with the overall sanitary napkin, enhancing the overall quality of the sanitary napkin. DETAILED DESCRIPTION

[0017] Various exemplary embodiments of the present invention will be described in detail below. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0018] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0019] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0020] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0021] The following is a further detailed description of a sanitary napkin contact layer using Ecocotyl fiber and its manufacturing process according to the present invention.

[0022] A sanitary napkin contact layer using EcoCosy fiber comprises an EcoCosy fiber layer, a surface layer, and a bottom layer. The surface of the EcoCosy fiber layer is provided with a three-dimensional concave-convex flow-guiding texture, which effectively guides the rapid diffusion of liquid, improving absorption speed and uniformity. The surface layer adheres to the surface of the EcoCosy fiber layer and has breathable micropores. The micropores ensure good air permeability, keeping private areas dry. The bottom layer is placed at the bottom of the EcoCosy fiber layer and ultrasonically welded to the sanitary napkin. Ultrasonic welding offers the advantages of strong welding and good sealing, ensuring a stable connection between the contact layer and the main body of the sanitary napkin.

[0023] Furthermore, the EcoCosy fiber layer has a diameter of 0.8D and a weight of 18g / m 2 This specific diameter and weight allows the EcoCosy fiber layer to have good absorption and load-bearing capacity while ensuring softness.

[0024] Furthermore, the pore size of the breathable micropores is 5-10 μm, and this pore size range can ensure sufficient air permeability and prevent liquid leakage.

[0025] The present invention also provides a process for manufacturing a sanitary napkin contact layer using EcoCosy fibers, which specifically comprises the following steps:

[0026] S1. Eco-Cosy Fiber Layer: Made with 100% Eco-Cosy fiber, this layer is created through a hot air permeation process to create a three-dimensional, concave and convex flow-guiding texture. This process precisely controls the fiber's shaping, ensuring the resulting three-dimensional, concave and convex flow-guiding texture meets design requirements, effectively improving the contact layer's flow-guiding performance.

[0027] S2. Surface Treatment: Plasma treatment creates a microporous structure on the surface of the Eucosil fiber layer. Plasma treatment technology can form uniform, tiny, breathable micropores on the fiber surface without damaging the fiber body, greatly improving the air permeability of the contact layer.

[0028] S3. Backing layer bonding: Ultrasonic welding is used to weld the Eco-Cotton fiber layer to the sanitary napkin. Ultrasonic welding technology is highly efficient, environmentally friendly, and provides consistent welding quality, ensuring a secure connection between the backing layer and the main body of the sanitary napkin.

[0029] The specific implementation process of the sanitary napkin contact layer using EcoSil fiber and its manufacturing process of the present invention is as follows:

[0030] 1. Raw material preparation: Ucosil fiber (0.8D, weight 18g / m 2 );

[0031] 2. Process steps:

[0032] S1, the fiber layer is formed by hot air penetration process (temperature 120℃, wind speed 2m / s);

[0033] S2, plasma treatment (power 50 W, time 30 seconds) to form micropores;

[0034] S3, ultrasonic welding machine (frequency 20kHz, pressure 0.3MPa) composite base film.

[0035] 3. Test results: air permeability 3650g / m 2 / 24h, absorption time 1.2 seconds.

[0036] The present invention and its implementation methods are described above. This description is not restrictive. If ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creatively designing them without departing from the purpose of the invention, they should all fall within the scope of protection of the present invention.
