What role can industrial staple fiber and rubber compound play?
The main characteristic of short fiber-rubber composites is to increase the modulus of the elastomer under small deformations while maintaining extremely low dynamic and static permanent deformation and high elasticity.

The main characteristic of short fiber-rubber composites is to increase the modulus of the elastomer under small deformations while maintaining extremely low dynamic and static permanent deformation and high elasticity. Short fiber is used as a filling and reinforcing material, and its addition imparts excellent properties such as high modulus, high strength, high tear strength, puncture resistance, impact resistance and vibration damping. Its intervention is beneficial to improve the stiffness and dimensional stability of semi-finished products, reduce the cost of products, simplify the process and improve production efficiency. Therefore, it has been widely used in many products of the rubber industry, and has improved the use performance and service life of the product.
The short fiber for rubber should be able to form good adhesion with the matrix rubber and be evenly dispersed. It does not break during the processing and maintains the original aspect ratio. Only the short fiber can play the role of reinforcing fiber, mixing The strength of the rubber can be improved. Variety of short fibers for rubber reinforcement; inorganic short fibers include glass fiber, asbestos fiber, and steel fiber; organic short fibers include lignin short fibers, nylon staple fibers, polyester staple fibers, and cotton staple fibers.
In order to make the addition of short fibers play its due role, that is, to improve the interfacial adhesion strength-reinforcing effect between the rubber and the rubber, the short fibers are generally pretreated. For short fibers of non-pretreated synthetic fibers, it is necessary to add the necessary adhesive to the rubber compound during application. However, the pretreated short fibers, such as glass fibers, are treated with a silane coupling agent to improve the interfacial properties of the glass fibers and have a certain compatibility with the rubber, so that the glass short fibers are easily dispersed and uniformly dispersed in the rubber compound. It has good adhesion to the rubber matrix and has good reinforcing effect on the product. Therefore, the application of pretreated short fibers is more effective in improving the quality of the products.
The effect of pretreating the short fibers is to increase the bond between the fibers and the rubber matrix while improving the length retention of the short fibers after mixing. The pretreatment currently applied is based on chemical treatment. Synthetic fibers and cellulosic staple fibers can be treated with an impregnating solution containing an adhesive such as styrene-butadiene latex or butadiene latex. It can also be treated with an impregnation solution containing neoprene latex.
