【発明の詳細な説明】
本発明は空気入りタイヤの補強材、特にカーカスとして
編布を用いた空気入りタイヤに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforcing material for a pneumatic tire, particularly to a pneumatic tire using a knitted fabric as the carcass.
一般に空気入りタイヤのカーカスは、主とじて補強要素
となるタイヤコードを経糸として配列するとともに該経
糸の間隔を保持するため経糸より細い緯糸を粗にすだれ
織とした織物が採用されている。Generally, the carcass of a pneumatic tire is made of a fabric in which tire cords, which serve as reinforcing elements, are arranged as warp threads, and the weft threads, which are thinner than the warp threads, are loosely woven to maintain the spacing between the warp threads.
このすだれ織物は経糸を交互に開口し緯糸を杼によって
打ちこみ筬打ちして経糸の上下を逆に開口し再び緯糸を
打ちこむことによって製織する。This blind fabric is woven by alternately opening the warp threads, driving the weft threads in with a shuttle, beating the cloth, then opening the warp threads upside down and driving the weft threads in again.
そしてすだれ織物を用いて例えばバイアスタイヤを製造
するには、経糸の配列方向に対して２０゜〜７０°の角
度で、すだれ織物を切断するとともにこれを相互に接合
してプライを作り、このプライの少なくとも２枚を用い
てドラム上で経糸が相互に交差するように円筒状カーカ
スを組立て、しかる後トロイド状のタイヤに形成する。To manufacture, for example, a bias tire using a blind fabric, the blind fabric is cut at an angle of 20° to 70° with respect to the warp arrangement direction, and the pieces are joined together to form a ply. A cylindrical carcass is assembled on a drum using at least two sheets of the above drum so that the warp threads intersect with each other, and then a toroidal tire is formed.
これらの諸工程において経糸と緯糸の固定が充分でない
ため経糸が動き易く、エンズ分布が不均一となり、タイ

物はその構造上経糸が波打ち、いわゆる「たたみ表」状

利となる。更にすだれ織物は開口を伴なうｅＡ織のため
生産能力に限界があり、しかも緯糸と経糸が滑らない材
質を選定する必要があり、従って緯糸に長繊維は使用し
難い問題点がある。In these various steps, the warp and weft are not sufficiently fixed, so the warp tends to move, resulting in uneven end distribution, which impairs tire durability. In addition, due to the structure of blind textiles, the warp yarns are wavy, resulting in a so-called "tatami matome" shape, which increases the thickness of the textile itself, and as a result, it is necessary to increase the thickness of the topping rubber to prevent the cords from touching each other. This is disadvantageous in terms of reducing the weight of the tire. Furthermore, since the blind fabric is an eA weave with openings, its production capacity is limited, and it is necessary to select a material that prevents the weft and warp from slipping, making it difficult to use long fibers for the weft.

である。The present invention is a pneumatic tire in which a reinforcing material is a ply made of silk fabric knitted with fine fiber silk threads, with warp threads arranged parallel to each other and the warp threads maintained at a constant distance from each other.

。An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a schematic diagram of the surface of silk cloth used in the pneumatic tire of the present invention. In the figure, the knitted fabric (1) is warp (
3) are arranged parallel to each other, and these warps are knitted with a plurality of fine fiber knitting yarns (5) and (6) along the longitudinal direction of the warp, thereby integrating the warp yarns and forming a knitted fabric. . The knitting method here can be a conventionally widely used method such as warp stockinette knitting or horizontal stockinette knitting.

化の観点から不利であり、更に絹糸と経糸とのこすれに
よる耐久性が低下する。Next, the silk thread used in the present invention may be made of any material that can sufficiently withstand general adhesive treatment and heat treatment conditions in tire manufacturing processes, and preferably can adhere to rubber after treatment, such as nylon-6, nylon-66, etc. A filament of an organic fiber such as polyester or the like with a fiber diameter of 5 to 50 deniers is used. Here, the filament diameter is 5
If it is smaller than the denier, the fixing strength between the warp and weft is not sufficient. On the other hand, if the filament diameter exceeds 50 deniers, the thickness of the knitted fabric increases, resulting in an increase in ply gauge, which is disadvantageous from the viewpoint of weight reduction, and furthermore, durability decreases due to rubbing between the silk thread and the warp thread.
上述の如くして得られた編布は従来から一般に採用され

In particular, when this knitted fabric is used as a carcass (when used), the warp yarns are uniformly 1vIlli in length during the process of forming the carcass ply into a troid shape, resulting in excellent uniformity of the finished tire and a smooth surface of the tire. The uneven surface is alleviated and the durability (even more improved).
