how many types of non woven fabric?
There are several types of nonwoven fabrics, each with its own characteristics and manufacturing processes. Here are some common types:
1.Spunbond Nonwoven Fabric: Spunbond fabric is made by extruding continuous filaments of thermoplastic polymers, such as polypropylene or polyester, and then bonding them together through heat and pressure. It is known for its strength, durability, and resistance to moisture. Spunbond fabrics are used in applications such as geotextiles, agriculture, and disposable products.
2.Meltblown Nonwoven Fabric: Meltblown fabric is produced by extruding very fine fibers of a thermoplastic polymer, typically polypropylene, and then blowing them with hot air to create a random fiber mat. The fibers are then bonded together through heat or by using a binder. Meltblown fabrics have excellent filtration properties and are commonly used in surgical masks, air filters, and oil sorbents.
3.Spunlace Nonwoven Fabric: Spunlace fabric, also known as hydroentangled fabric, is produced by entangling fibers together using high-pressure water jets. This process creates a fabric with good strength, softness, and absorbency. Spunlace fabrics are commonly used in wipes, medical products, and hygiene applications.
4.Needle-punched Nonwoven Fabric: Needle-punched fabric is made by mechanically interlocking fibers together using barbed needles. The needles repeatedly pass through the fiber web, entangling the fibers and creating a cohesive fabric structure. Needle-punched fabrics are known for their strength, stability, and dimensional stability. They are used in applications such as carpets, automotive interiors, and filtration media.
5.Thermal Bonded Nonwoven Fabric: Thermal bonded fabric is produced by applying heat and pressure to a fiber web, causing the fibers to melt and bond together. This process creates a fabric with good strength and stability. Thermal bonded fabrics are used in applications such as upholstery, bedding, and filtration.
6.Chemical Bonded Nonwoven Fabric: Chemical bonded fabric is made by applying a chemical binder to a fiber web and then curing it to bond the fibers together. This process creates a fabric with good strength and stability. Chemical bonded fabrics are used in applications such as interlinings, apparel, and upholstery.
These are just a few examples of the many types of nonwoven fabrics available. Each type has unique properties that make it suitable for specific applications in various industries.
