Spunbond nonwoven fabric is a type of nonwoven fabric made by a process called spunbonding. In this process, a polymer is extruded through a spinneret (a device with multiple small holes) and the resulting filaments are drawn and stretched by high-speed hot air streams before they are laid down onto a moving conveyor belt, forming a web of randomly oriented fibers. The fibers are then bonded together using heat, pressure, or chemicals to create a strong, stable fabric.
Spunbond nonwoven fabrics have several functional characteristics that make them useful for a wide range of applications, including:
1.High strength and durability: The fibers in spunbond nonwoven fabrics are strongly bonded together, making the fabric strong and resistant to tearing. This is important for applications that require a durable and long-lasting material.
2.Lightweight and breathable: Spunbond nonwoven fabrics are lightweight and porous, which allows air and moisture to pass through easily. This makes them suitable for applications such as clothing, medical and hygiene products, and industrial filters.
3.Good barrier properties: Spunbond nonwoven fabrics can be made with certain types of fibers that provide barrier properties against liquids, gases, and microorganisms. This makes them suitable for applications such as protective clothing, medical gowns and drapes, and industrial filters.
4.Chemical resistance: Some types of Spunbond nonwoven fabrics have good chemical resistance, making them suitable for applications such as industrial wipes and filters.
5.Absorbency: Some types of Spunbond nonwoven fabrics have good absorbency, making them suitable for applications such as medical and hygiene products, and wipes.
6.Versatility: Spunbond nonwoven fabrics can be made in a wide range of thicknesses, colors, and patterns, and can be customized for specific applications, such as medical and hygiene products, agricultural products, and construction products.
7.Eco-friendly: Spunbond nonwoven fabrics are made from thermoplastic polymers, which can be recycled or incinerated without producing toxic by-products, making them more environmentally friendly than some other types of fabrics.
8.Cost-effective: Spunbond nonwoven fabrics are cost-effective, making them a suitable choice for a wide range of applications, from disposable products to industrial filters.
