Nonwoven fabrics come in various types and structures, each with its unique characteristics and applications. China Nonwoven Fabric suppliers tell you some common types and structures of nonwoven fabrics:
1.Spunbond Nonwoven: Spunbond nonwoven fabrics are made by extruding continuous filaments of thermoplastic polymers, such as polypropylene or polyester. The filaments are then laid down in a random arrangement and bonded together using heat and pressure. Spunbond fabrics have a flat and uniform appearance, high strength, and good breathability. They are widely used in medical, hygiene, and geotextile applications.
2.Meltblown Nonwoven: Meltblown nonwoven fabrics are produced by melting thermoplastic polymers and extruding them through fine nozzles to form microfibers. The microfibers are then cooled and collected to create a nonwoven fabric. Meltblown fabrics have a fine fiber structure, high filtration efficiency, and excellent fluid resistance. They are commonly used in filtration media, medical masks, and absorbent products.
3.Spunlace Nonwoven: Spunlace nonwoven fabrics are created by entangling fibers using high-pressure water jets. The entanglement process results in a fabric with excellent strength, softness, and absorbency. Spunlace fabrics are often used in wipes, medical applications, and apparel.
4.Needle-punched Nonwoven: Needle-punched nonwoven fabrics are produced by mechanically entangling fibers using barbed needles. The needles penetrate the fibers, interlocking them and creating a cohesive fabric structure. Needle-punched fabrics have good dimensional stability, high strength, and durability. They find applications in automotive, filtration, and geotextile industries.
5.Chemical-bonded Nonwoven: Chemical-bonded nonwoven fabrics are created by applying chemical binders to the fibers to bond them together. The chemical binders can be activated by heat, pressure, or solvents. These fabrics offer versatility in terms of softness, strength, and absorbency and are commonly used in hygiene products, apparel, and automotive applications.
6.Composite Nonwoven: Composite nonwoven fabrics are made by combining multiple layers or types of nonwoven fabrics together. This can be achieved through bonding, lamination, or adhesive processes. Composite nonwovens offer enhanced properties, such as improved strength, barrier properties, or filtration efficiency. They are used in various applications, including medical, automotive, and protective clothing.
7.Stitch-bonded Nonwoven: Stitch-bonded nonwoven fabrics are created by mechanically interlocking fibers using stitching techniques. The stitches secure the fibers, creating a fabric with good dimensional stability and strength. Stitch-bonded fabrics are used in applications such as upholstery, geotextiles, and mattress covers.
