Problems solved by technology

[0003] At present, in order to improve the bonding strength between polyester soft cord and rubber, adhesive activated filaments are generally used as raw materials instead of ordinary polyester filaments. However, the adhesive activity of activated filaments has the characteristics of decaying with time. Special attention should be paid to avoiding the effect of heat, direct light and chemical pollution, and the production cost of adhesive activated filament is much higher than that of ordinary polyester filament, and the polyester cord produced by it is also relatively hard, so use Although this method has high adhesive force, the V-belt produced is hard
