Abstract
Description
Technical Field
[0001] This utility model relates to a medical hydrophilic spunlace nonwoven fabric, belonging to the technical field of medical spunlace nonwoven fabrics. Background Technology
[0002] Disposable medical bed sheets are typically made of nonwoven fabric, often using polypropylene spunbond laminated nonwoven fabric. High-end bed sheets are often made of laminated nonwoven fabric. Polypropylene spunbond laminated nonwoven fabric is made by using polypropylene spunbond fabric as the base fabric and then preparing it through a lamination process.
[0003] Polypropylene spunbond fabric is manufactured using a melt extrusion process, resulting in a low price. However, the fiber fineness is generally between 20-100μm, producing a stiff and dense fabric that does not absorb moisture. When used as medical bed sheets, polypropylene spunbond laminated nonwoven fabric offers poor comfort and absorbency, as well as poor antibacterial properties. Liquids can also remain on the surface of the medical bed sheets, affecting the user. Viscose hydroentangled nonwoven fabric, due to the high absorbency of its viscose fibers, does not easily diffuse. Therefore, the challenge lies in developing a medical hydrophilic hydroentangled nonwoven fabric that is hydrophilic on the surface, does not retain moisture, and allows for rapid diffusion. Utility Model Content
[0004] The purpose of this invention is to provide a medical hydrophilic spunlace nonwoven fabric with a surface made of polyester fibers containing a hydrophilic agent, which has a hydrophilic effect and does not store liquid.
[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:
[0006] The present invention relates to a medical hydrophilic spunlace nonwoven fabric, comprising a polyester fiber layer, a biomass graphene viscose fiber layer, and an artemisia fiber layer, which are composites of hydrospunlace phases.
[0007] The polyester fiber layer is formed by parallel laying of polyester fibers, the cross-section of the polyester fibers is cross-shaped or Y-shaped, and the surface of the polyester fibers is coated with a hydrophilic agent.
[0008] The biomass graphene viscose fiber layer is formed by cross-laid biomass graphene viscose fibers.
[0009] The side of the Artemisia argyi fiber layer away from the biomass graphene viscose fiber layer is laminated with a polypropylene spunbond nonwoven fabric layer.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the mugwort fiber layer is formed by cross-laid mugwort fibers.
[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the mugwort fiber is mugwort modified bamboo pulp fiber.
[0012] Based on the above scheme and as a preferred embodiment of the above scheme: a PE coating layer is provided on the surface of the polypropylene spunbond nonwoven fabric layer away from the Artemisia argyi fiber layer.
[0013] Based on the above scheme and as a preferred embodiment of the above scheme: a mesh cloth layer is provided between the biomass graphene viscose fiber layer and the artemisia fiber layer.
[0014] The beneficial effects of this utility model are as follows: The medical hydrophilic spunlace nonwoven fabric involved in this utility model uses polyester fibers with irregular cross-sections and hydrophilic agents coated on the surface, which are hydrophilic and can diffuse rapidly. The use of biomass graphene viscose fiber layers and artemisia fiber layers provides high water absorption and a certain antibacterial effect. The polypropylene spunbond nonwoven fabric layer used has a water-repellent effect and can prevent moisture penetration. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the structure of the medical hydrophilic spunlace nonwoven fabric involved in Example 1;
[0016] Figure 2 This is a schematic diagram of the structure of the medical hydrophilic spunlace nonwoven fabric involved in Example 2. Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] Example 1
[0019] Combination Figure 1 This embodiment provides a detailed description. The medical hydrophilic spunlace nonwoven fabric involved in this embodiment includes a polyester fiber layer 1, a biomass graphene viscose fiber layer 2, and an artemisia fiber layer 3, all composited with a hydrospunlace phase. The polyester fiber layer 1 is formed by parallel laying of polyester fibers, the cross-section of which is cross-shaped or Y-shaped, and a hydrophilic agent is attached to the surface of the polyester fibers. The biomass graphene viscose fiber layer 2 is formed by cross-laying of biomass graphene viscose fibers. A polypropylene spunbond nonwoven fabric layer 4 is composited on the side of the artemisia fiber layer 3 away from the biomass graphene viscose fiber layer 2.
[0020] The polyester fiber surface is coated with a hydrophilic agent, which enhances the hydrophilicity of the polyester fiber layer. The parallel web formation and Y-shaped cross-sectional structure of the polyester fibers increase the diffusion rate of liquids on the polyester fiber layer 1. The biomass graphene viscose fiber layer 2, being a viscose fiber, has excellent moisture absorption properties, thus absorbing liquids from the polyester fiber layer 1 and preventing moisture retention, thereby improving the user experience.
[0021] The second layer of biomass graphene viscose fiber employs a cross-laid web technique, which reduces the difference in longitudinal and transverse strength between the medical hydrophilic spunlace nonwoven fabric. The biomass graphene viscose fiber is produced by thoroughly mixing graphene oxide emulsion and viscose slurry, followed by wet spinning. Biomass graphene exhibits excellent antibacterial properties when interacting with bacteria, and its functional fabric possesses comprehensive functions such as odor absorption, moisture absorption, and breathability. Testing revealed that the biomass graphene fiber fabric exhibits excellent antibacterial properties, with a bactericidal activity value greater than 5.5 and an inhibitory activity value greater than 9.3 against Staphylococcus aureus ATCC6538P; and a bactericidal activity value greater than 6.0 and an inhibitory activity value greater than 8.8 against Escherichia coli ATCC25922.
[0022] The Artemisia fiber layer 3 is formed by cross-laid Artemisia fibers, which has the same effect and can reduce the difference in longitudinal and transverse strength of the medical hydrophilic spunlace nonwoven fabric.
[0023] Specifically, in this embodiment, the areal density of polyester fiber layer 1 is 1 gram per square meter, the areal density of biomass graphene viscose fiber layer 2 is 25 grams per square meter, and the areal density of artemisia fiber layer 3 is 25 grams per square meter. Of course, the areal density of each layer can also be adjusted according to actual needs.
[0024] Furthermore, the mugwort fiber is mugwort-modified bamboo pulp fiber. Mugwort is a perennial herbaceous plant of the Asteraceae family. Mugwort leaves contain a variety of organic compounds beneficial to the human body, the main components of which are tea polyphenols, caffeine, and polysaccharides, etc., which have natural health benefits. Mugwort-modified bamboo pulp fiber is a new type of functional viscose fiber obtained by extracting effective natural substances from mugwort leaves and blending them with spinning solution during the spinning process. A unique process is used to evenly distribute the natural extracts from mugwort leaves within the mugwort bamboo pulp fiber. Bamboo pulp fiber is a new type of regenerated cellulose fiber manufactured using renewable bamboo resources through a special process. It retains the original antibacterial and bacteriostatic effects of bamboo, while also having good moisture absorption and breathability.
[0025] Example 2
[0026] Combination Figure 2 This embodiment will be described in detail below. The difference between the medical hydrophilic spunlace nonwoven fabric involved in this embodiment and that in Embodiment 1 is that a PE coating layer 5 is provided on the surface of the polypropylene spunbond nonwoven fabric layer 4 away from the Artemisia argyi fiber layer 3, which has a waterproof effect.
[0027] Another difference from Example 1 is that a mesh fabric layer 6 is provided between the biomass graphene viscose fiber layer 2 and the artemisia fiber layer 3. The mesh fabric layer 6 is woven from nylon filaments and has holes with a side length of 3-5cm.
[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
