What is nonwoven fabric made of?

Nonwoven fabric is a type of fabric that is engineered by bonding or interlocking fibers together mechanically, chemically, or thermally, rather than weaving or knitting yarns together. It's made from various types of fibers or filaments, both natural and synthetic. Some common materials used to produce nonwoven fabrics include:

1. Polyester: It's a synthetic material that offers durability and strength. Polyester fibers are commonly used in nonwoven fabrics for applications like geotextiles, filtration, and automotive products.

2. Polypropylene: This thermoplastic polymer is known for its moisture resistance and is frequently used in nonwoven fabrics for applications like medical masks, disposable garments, and diapers.

3. Polyethylene: Another thermoplastic polymer, polyethylene, is used in nonwoven fabrics for its softness and strength. It's often utilized in products like protective clothing, packaging, and agricultural covers.

4. Rayon: This semi-synthetic fiber, derived from cellulose, offers a soft feel and good absorbency. It's used in nonwoven fabrics for products like baby wipes, feminine hygiene products, and medical supplies.

5. Cotton: Although less common due to cost and processing considerations, cotton fibers can also be used to make nonwoven fabrics, offering natural softness and breathability.

The process of making nonwoven fabric involves various methods such as spunbond, meltblown, needle punching, and thermal bonding. Each method utilizes different techniques to create nonwoven fabrics with specific properties suitable for diverse applications.
