Non woven fabric production process

The main raw materials for fabric are polypropylene (PP) and polyester (PET), which are its main components. These two materials are the core components. In addition, cotton non-woven fabric uses natural fibers such as cotton, which is a type of plant fiber. In short, materials such as polypropylene, polyester, nylon, and wood pulp are applications of composite materials.

 

Non woven fabrics do not require spinning or weaving, but rather fibers are reinforced into fabric through mechanical, thermal bonding, or chemical methods. The choice of material will affect the production process, such as the use of different fiber materials for methods such as heat sealing and water jet bonding.

 

The environmental characteristics of non-woven fabrics are biodegradable, which is related to the material. For example, polypropylene and polyester have different decomposition times in nature, while wood pulp fibers have better biodegradability.

 

Different application areas may use different materials. For example, the healthcare sector may use non-woven fabrics made of polypropylene or polyester, while agricultural or industrial applications may use composite materials or add other functional fibers such as activated carbon. Materials corresponding to various application scenarios.

 

Other materials, such as cellulose fibers (cotton, linen), composite materials (such as PP and PE composites), and recycled polyester, are all components of non-woven fabrics and belong to more specialized or special-purpose materials.
