The raw material for nonwovens is mainly derived from a variety of natural and synthetic fibers. These fibers can be either short or long and are selected according to their specific production process needs.

1. Natural fibers:

Natural fibers are one of the main raw materials for nonwoven fabrics. These include cotton, hemp, wool, etc. These fibers have good air permeability and are naturally biodegradable. Cotton is the most commonly used natural fiber, and the nonwoven fabrics made from it are soft, moisture-absorbent, and are widely used in the fields of medical care, hygiene, and household products.

2. Synthetic fiber:

Synthetic fibers are also important raw materials for nonwoven fabrics, such as polyester fibers and polypropylene fibers. These fibers have good chemical stability and wrinkle resistance. For example, nonwoven fabrics made of polypropylene fibers have high strength and durability and are widely used in packaging, agriculture and construction.

3. Specialty fibers:

In addition to common natural and synthetic fibers, a number of specialty fibers are also used in the manufacture of nonwoven fabrics. These specialty fibers include carbon fiber, glass fiber and aramid. They have unique properties and characteristics, such as high strength, high modulus, high temperature resistance, etc., so they are widely used in aviation, automotive and high-end manufacturing and other fields.

During the production of nonwoven fabrics, these fibers are subjected to specific processes, such as thermal bonding, chemical bonding or mechanical bonding, so that they form a continuous structure. This production process gives nonwoven fabrics unique properties such as softness, breathability, waterproofing and moisture resistance.

Overall, nonwovens are made from a variety of raw materials, including natural fibers, synthetic fibers and specialty fibers. The choice of raw material depends on the use and performance requirements of the product. With the advancement of science and technology, the raw materials for nonwoven fabrics are constantly being innovated and expanded to meet the needs of various fields.
