There are several main types of nonwoven fabrics, each with its unique characteristics and applications.
Spunbond nonwoven fabric is produced by extruding fibres through a spinneret and then randomly depositing them onto a conveyor belt. The fibres are then bonded together using various techniques such as thermal bonding or chemical bonding. This type of nonwoven fabric is characterized by its softness, drapeability, and high tensile strength. It is widely used in applications such as clothing, medical dressings, and filters.
Interlaced nonwoven fabric is produced by interlacing fibres or filaments using a mechanical process. This type of nonwoven fabric has a velvet-like texture and is characterized by its high tensile strength and abrasion resistance. It is commonly used in applications such as upholstery, automotive interior materials, and clothing.
Needled nonwoven fabric is produced by interlacing fibres or filaments using a needle-punching process. This type of nonwoven fabric has a dense structure and is characterized by its high tensile strength, abrasion resistance, and tear resistance. It is commonly used in applications such as filters, insulation materials, and upholstery.
Molded fiber nonwoven fabric is produced by extruding a molten polymer through a die and then depositing it onto a conveyor belt. The extruded fibres are then cooled and bonded together using various techniques such as thermal bonding or chemical bonding. This type of nonwoven fabric is characterized by its three-dimensional structure, high tensile strength, and abrasion resistance. It is commonly used in applications such as automotive interior materials, filters, and upholstery.
Composite nonwoven fabrics are produced by combining two or more types of nonwoven fabrics together. This can be achieved through various methods such as lamination or needle-punching. Composite nonwoven fabrics offer a combination of properties from the different constituent materials and are commonly used in applications where specific physical properties are required.
Overall, the different types of nonwoven fabrics each have their unique characteristics and applications. The selection of the appropriate type of nonwoven fabric depends on the specific requirements of the application and the desired performance characteristics.
