Frequently Asked Questions

What are the three main types of non woven fabric?

The three main types of non-woven fabrics are:

1)Spunbond non-woven fabric: Spunbond non-woven fabric is made by spinning and bonding continuous filaments of polyester or polypropylene fibers. This type of non-woven fabric is lightweight, strong, and breathable, making it suitable for a wide range of applications, such as medical masks, disposable gowns, and hygiene products.

2)Meltblown non-woven fabric: Meltblown non-woven fabric is made by extruding melted polymer fibers through tiny nozzles and then cooling and solidifying them to create a web of fine fibers. This type of non-woven fabric has excellent filtration properties, making it suitable for use in face masks, air filters, and other filtration applications.

3)Needle punched non-woven fabric: Needle punched non-woven fabric is made by mechanically punching fibers together to create a web of tangled fibers. This type of non-woven fabric is durable, strong, and often used for applications such as geotextiles, carpet backing, and insulation. Needle punched non-woven fabric can be made from a variety of fibers, including polyester, polypropylene, and natural fibers such as wool or cotton.
