Conveyor belts can use a variety of fibers as belt core materials. The following are several common fiber types:
Nylon fiber: It has the characteristics of high strength, high toughness, wear resistance, corrosion resistance, and high temperature resistance. It is widely used in the manufacture of conveyor belts.
Polyester fiber: It also has excellent strength and wear resistance. It is made by chemical synthesis and spinning technology. It is another common material for manufacturing conveyor belts.Polyester conveyor belt also called EP conveyor belt, which tension resistant body is canvas that is woven by polyester in wrap and polyamide in weft.
Cotton fiber: Although it has low strength, it is easy to bond with rubber and has a certain wet strength improvement. It was once widely used in the manufacture of conveyor belts, but its use is decreasing due to its low breaking strength and poor corrosion and mildew resistance.
Hemp fiber: It is mainly used to manufacture packaging fabrics and ropes. Some high-quality hemp fibers can also be used to make clothing, but it is less used in conveyor belt manufacturing.
Glass fiber: Although it is considered to be the best skeleton material with small elongation and moderate linear expansion coefficient, it is not widely used due to cost and other limitations.
Aramid fiber: It is expected that it may partially replace glass fiber in the future and become one of the best skeleton materials for toothed belts.
Vinylon fiber: It is used in China, Japan and other countries. It has lower strength and elastic elongation than nylon fiber and better heat resistance, but its strength will decrease when wet.
Chemical fiber in recycled rubber conveyor belt: such as nylon and polyester, after dipping, it has good adhesion with rubber and is suitable for light conveyor belts and flat conveyor belts.
The choice of which fiber to use in the manufacture of conveyor belts depends on the specific application conditions, including the purpose of the conveyor belt, the load it bears, the ambient temperature and chemical corrosiveness. Nylon and polyester are usually the preferred materials for manufacturing conveyor belts due to their excellent physical and chemical properties.
