キシナフトエ酸、ビスフェノール、テレフタル酸。The molten liquid crystalline wholly aromatic polyester herein refers to a polyester whose main chain is composed of repeating units of aromatic rings, and which exhibits a liquid crystal state when melted. To this extent,
There is no problem even if an aliphatic ring or the like is copolymerized as a trace component in the polyester main chain. Examples of polyesters according to the invention include hydroxybenzoic acid, hydroxynaphthoic acid, bisphenol, terephthalic acid as monomers.

用いられる。In the present invention, the polyarylate fiber can be used alone as a cord or in combination with other fibers to make a tire cover, but it is also possible to use this cord as a tire cover by embedding VC in the rubber and making it strong. In particular, the latter has better wear resistance (life) than the former. Regarding the thickness of the fibers used for the tire cover, the thickness of the cord, the specific structure of the cover, etc., those used in conventional organic fiber tire covers are used.

ぞれコードの最初の切断が観察された。A tire cover with an open-knit structure was made from both cords (diameter 71), and was mounted on a 550 cc passenger car and tested by actual driving on a paved road for 1.5 hours at a time. We investigated the estimated lifespan of the tire cover (7) and the number of times the tire cover was driven until the first part of the cord broke.As a result, the tire cover according to the present invention
The first breakage of the cord was observed at the 5th time and at the 17th time using the tire cover U of the comparative example.

観察された。As another example, a similar tire cover was prepared using cords (diameter 9) in which cords each having a diameter of 5 m were embedded in rubber, and the same actual driving test as in Example 7 was conducted. As a result, the first breakage of the tire cover made of the rubber cord embedded with the polyarylate fiber cord according to the present invention was observed at the 34th time, and the first breakage of the tire cover made of the rubber cord embedded with the polyethylene terephthalate fiber cord was observed at the 20th time.
