On the selection and choice of the fiber and fabric structure used in the base cloth of rubber products
Rubber fabric composite is composed of fiber fabric reinforced material and ductile rubber matrix. Compared with thermosetting or thermoplastic polymer fabric composite, it has larger deformation range, higher bearing capacity and good fatigue resistance. Base fabric is the skeleton of coated fabric, its performance greatly affects the performance of the final product. In rubber products, the base fabric, namely fiber fabric reinforcement material, mainly plays the role of supporting and maintaining the appearance size. It is very key to improve the physical properties of rubber products, such as impact resistance, tear resistance, wear resistance and fatigue resistance. The choice of fiber and fabric structure for the base cloth of rubber products depends on the type of product and its final performance. The basic requirements are as follows. Good adhesion to rubber. Not only requires the initial adhesive strength is high, more important is the durability of the adhesive, this is because the rubber products in the actual use of the process to be affected by various adverse factors of destruction, the rubber layer and the base cloth between the local separation phenomenon, and gradually expand, resulting in a serious impact on the appearance of products and the use of the effect. The deformation of the base cloth under the action of external force and the deformation of the surface coated adhesive layer should be as close as possible and stable, so as to effectively prevent the cracking phenomenon of rubber products under the action of dynamic load. Suitable for the production of rubber products, not only to ensure good cloth flatness, but also to try to ensure the same physical properties in each direction. The selection of fiber materials The five main fiber types used in rubber reinforcement materials are cotton fiber, rayon fiber, nylon fiber, polyester fiber and aramid fiber, etc.
