Needle punched non-woven fabric is a type of non-woven fabric made through mechanical needle punching technology. The core principle is to repeatedly puncture the fiber web with barbed needles, causing the fibers to entangle and hook together, ultimately forming a non-woven material with certain strength and structure.
Main features:
Non spinning process: No spinning or weaving is required, it is directly reinforced by fiber mesh.
Physical entanglement: Using needles to entangle fibers, rather than chemical or thermal bonding.
Fluffy structure: The fibers have a three-dimensional mesh structure, high porosity, and good breathability.
Adjustable performance: By adjusting parameters such as fiber type and needle density, thickness, strength, and softness can be controlled.
Production process flow:
Fiber opening and mixing (such as polyester, polypropylene, aramid, etc.)
Sort into a net (form a fiber layer)
Acupuncture reinforcement (piercing up and down with a needle to entangle fibers)
Post finishing (such as heat setting, coating, calendering, etc.)
Application areas:
Industrial use: filter materials (air/liquid filtration), geotextiles (roadbed reinforcement), sound insulation materials.
Home decoration: carpet base cloth, wall cloth, sofa lining.
Automotive industry: interior materials, soundproofing felt.
Environmental protection field: oil pollution adsorption materials, waterproof membrane base cloth.
Other: synthetic leather base fabric, military protective materials, etc.
Advantages:
Low cost: fast production speed and strong adaptability to raw materials.
Environmental Protection: Recyclable and partially biodegradable.
Multifunctional: Enhance performance by combining other materials such as films and coatings.
Compared with heat bonded and water jet non-woven fabrics, needle punched non-woven fabrics focus more on high strength and durability, but have lower surface fineness.
