The invention provides a rubber tire cord fabric. The cord fabric comprises yarns and is formed by weaving the plurality of yarns; the yarns are high-modulus and low-shrinkage strong yarns; and the plurality of yarns are knitted to form a knitted fabric with certain elasticity. The cord fabric is woven into a cord fabric layer of a tire; certain gaps are formed between the multiple yarns; in the driving process, when rubber is straightened and deformed, under stress, the multiple yarns firstly extrude the rubber in the gaps to deform the rubber till the multiple yarns get close to one another and the woven yarns are tightly attached to one another and tensioned; and by designing the structure, a large amount of heat generated by further deformation of the rubber can be avoided, the situation that the rubber loses elasticity due to sharp rising of the temperature of the solid tire is avoided, the solid tire can be applied to a higher-speed driving scene or a scene bearing larger pressure, and meanwhile the effective buffering effect can be achieved.
本发明提供一种橡胶轮胎帘子布,包括纱线,由若干所述纱线编织而成;所述纱线为高模低缩的强力丝;若干所述纱线经过针织而成的具有一定弹性的针织织物;本发明编织成轮胎的帘子布层,若干所述纱线之间均具有一定的间隙,在行驶时,橡胶拉直并产生形变时,在受力状态下,若干所述纱线先挤压间隙内的橡胶进行变形,直至若干所述纱线相互靠近,直至编织而成的所述纱线相互紧贴拉紧;通过设计此结构,可以避免橡胶进一步形变产生大量热量,避免实心轮胎温度急剧升高导致橡胶失去弹性,可以让实心轮胎运用于更高速的行驶情景,或承受更大压力的场景下使用,同时还能达到有效缓冲效果。
