    Abstract: The invention is directed to fabric-based inserts and layers for use with tires in order to provide an improved level of puncture resistance to the tire. Disclosed embodiments of the invention include tire anti-puncture layers including puncture-resistant layers that comprise a single or multiple layers of fabric. Prererably, for low cost and low abrasion, the puncture-resistant layers comprise fibers having a tensile strength or tenacity of less than about 15g/denier. In some preferred constructions, especially where the puncture-resistant layer comprises a single layer of fabric, the puncture-resistant layer comprises a high cover factor, tightly woven fabric, for example having a round packed cover factor of at least about 40 % of full in the warp direction and at least 65 % of full in the fill direction. In other embodiments, especially where the puncture-resistant layer comprises multiple layers of fabric, lower cover, less tightly woven fabrics can be used, or, alternatively, non-woven fabrics such as knitted or felted fabrics (felts) can be used. Some such preferred, less tightly-woven fabrics are woven from untwisted yarns, enabling the fibers or filaments comprising the yarns to spread out into a tape-like configuration under compression, thereby increasing the effective cover factor and level of puncture resistance over that predicted from the round packed cover factor. A "taped fiber density" calculation is presented for predicting the effective cover factor of such tape-out woven fabrics, and certain preferred embodiments of such fabrics have a tape fiber density of at least about 80 % of full in at least one of the warp and fill directions. In some embodiments, the puncture-resistant layer, or one or more layers of fabric comprising the layer, are coated with polymeric coatings to increase the level of puncture resistance. In some embodiments, the tire anti-puncture device is configured as a separable strip that can be placed within a tire to act as a liner. In other embodiments, the puncture-resistant device is incorporated within the cross-section of the tire body itself. While the tire anti-puncture device in some embodiments comprises just the puncture-resistant layer, in other embodiments, one or more low abrasion layers can be added to isolate and protect the tire and/or inner tube, if present, from the puncture-resistant layer. Such law abrasion layer(s) are particularly useful for embodiments involving puncture-resistant layers coated with polymeric coatings containing fillers, which can server to increase puncture resistance but tent also to increase abrasiveness of the puncture-resistant layer.

    Abstract translation: 本发明涉及用于轮胎的基于织物的插入件和层，以便提供对轮胎的抗穿刺性的改进的水平。 本发明的公开的实施方案包括轮胎抗穿刺层，其包括包含单层或多层织物的抗穿刺层。 优选地，为了低成本和低磨损，抗穿刺层包括抗拉强度或韧度小于约15g /旦的纤维。 在一些优选的结构中，特别是在抗穿刺层包含单层织物的地方，抗穿刺层包括高覆盖系数，紧密织造的织物，例如具有至少约40％满的圆形包装覆盖系数 在经向方向上，并且在填充方向上至少65％满。 在其它实施方案中，特别是在抗穿刺层包含多层织物的情况下，可以使用下盖，较不紧密织造的织物，或者可以使用诸如针织或毡制织物（毛毡）的无纺织物。 一些这样优选的，较不紧密织物的织物由未卷曲的纱线编织，使得包含纱线的纤维或细丝在压缩下能够展开成带状构型，从而增加了有效覆盖系数和穿刺抗性水平超过 圆形封面系数。 提出了一种“胶带纤维密度”计算，用于预测这种无纺织物的有效覆盖系数，并且这种织物的某些优选实施方案在至少一个经纱中具有至少约80％的带状纤维密度 并填写方向。 在一些实施方案中，抗穿刺层或包含该层的一层或多层织物涂覆聚合物涂层以提高抗穿刺性水平。 在一些实施例中，轮胎抗穿刺装置被配置为可以放置在轮胎内以用作衬垫的可分离带。 在其它实施例中，抗穿刺装置并入轮胎主体本身的横截面内。 尽管在一些实施例中，轮胎防刺穿装置仅包括耐刺穿层，但是在其他实施例中，可以添加一个或多个低磨损层，以从轮胎穿刺装置隔离并保护轮胎和/或内胎管（如果存在） 耐层。 这种法律磨损层对于包含含有填料的聚合物涂层的抗穿刺层的实施方案是特别有用的，其可以服用于增加抗穿刺性，但是也增加了抗穿刺层的磨损性。
