The use and classification of non-woven fabrics

Non woven fabric is a fabric material made without the need for traditional textile processing. It combines fibers directly together through chemical or mechanical methods to form a cloth like structure, which has many characteristics of traditional textiles, such as softness, moisture absorption, and durability. Non woven fabrics are widely used in various industries due to their unique manufacturing methods and performance characteristics. The use of non-woven fabrics in the medical field: non-woven fabrics are often used to make medical masks, surgical gowns, bandages, and other medical supplies. They have good filtering and blocking properties, which can effectively prevent the spread of bacteria and viruses. Personal care products: sanitary napkins, diapers, facial mask and other personal care products use a large number of non-woven fabrics. Non woven fabrics can better absorb liquids and keep the skin dry. Industrial materials: Non woven fabrics are used as insulation materials, filtering media, sound insulation materials, and packaging materials. They can be customized with different thicknesses and strengths as needed to meet the requirements of specific applications. Home decoration: Non woven fabrics are used in home decoration to make curtains, wallpaper, and furniture fabrics. Non woven fabrics have excellent tear resistance and fire resistance, making them suitable for indoor use. Agriculture and Horticulture: Non woven fabrics can be used as mulching materials to control soil temperature and water evaporation. In addition, they can also be made into plant growth bags and seedling trays. Automotive industry: Non woven fabrics have applications in automotive interiors, roofs, and floor mats. Non woven fabric not only looks beautiful but also improves the thermal insulation effect of vehicles. Aerospace: In the high-tech industry, non-woven fabrics are used as materials for aircraft internal components because they are both lightweight and sturdy. Environmental protection: Non woven fabrics are used to produce garbage bags, shopping bags, and other environmentally friendly products. They can help reduce the use of plastic and protect the environment. Sportswear: High performance sportswear often uses non-woven fabric as one of the materials, as its breathability and sweat wicking properties help athletes perform well. The classification of non-woven fabrics can be divided into the following categories based on their manufacturing process and the raw materials used: 1 Melt Blown Non woven Fabric: This method involves melting the polymer into fine fibers and blowing them away through a nozzle into tiny bundles of fibers. These fibers are randomly distributed to form very thin layers, which are commonly used in efficient particle traps (HEPA) in air purifiers and medical masks. 2. Spunbond Nonwoven Fabric: In this process, polymer filaments are extruded from the spinneret and solidified into a continuous filament mesh in the air. This type of non-woven fabric is commonly used for making diapers and disposable tablecloths because it has high tensile strength and toughness. 3. Needlepunched Nonwoven Fabric: This method is formed by using a large needle to penetrate the fiber layer and interweave them together. This makes the final product more sturdy and has better dimensional stability. Needle punched non-woven fabric is commonly used for carpet backing and filtering materials. 4. Hydroentangled non-woven fabric: In this method, high-pressure water flows through the fiber layer, causing it to entangle and form a tight structure. Spunlaced non-woven fabric is used in wet wipes and personal care products due to its excellent moisture absorption ability and hand feel. 5. Chemical bonded nonwovens: Fiber fixation is achieved by reacting the interfaces between fibers through chemical crosslinking agents or resins. This type of non-woven fabric is commonly used for industrial applications, such as roof waterproofing membranes. As a multifunctional material, non-woven fabrics are increasingly being applied in many fields. With the continuous advancement of technology, more types of non-woven fabrics and their application methods may be developed in the future.
