Abstract
The invention discloses a compound thread rope used in tires. The compound thread rope comprises polyester threads and nylon threads, wherein the nylon threads are spirally wound on the polyester threads; the polyester threads include first polyester threads and second polyester threads; the nylon threads include first nylon threads and second nylon threads; the first nylon threads are spirally wound on the first polyester threads so as to form a first strand of threads, the second nylon threads are spirally wound on the second polyester threads so as to form a second strand of threads; and after the first strand of threads and the second strand of threads are subjected to twisting in a blended manner, the first polyester thread between adjacent two spiral first nylon threads on the first strand of threads is adhered to the second polyester thread between adjacent two spiral second nylon threads on the second strand of threads. Because of adopting the structure, the compound thread rope with the structure can fully utilize the adhesion property of nylons and the dimensional stability of polyesters. The adhesive-force retention rate of the compound thread rope subjected to high temperature is obviously superior to that of the polyester and similar to that of the nylon; and the properties of the tire using the thread rope disclosed by the invention is far higher than the national standards, and the durability and the high speed performance of the tire are superior to those of the common polyester cord threads.
Description
Technical field
The present invention relates to a kind of wire rod of tire used.
Background technology
At present, the synthetic fiber that use wherein use the most extensive with terylene, nylon and aramid fiber as reinforcing material more in tire.Polyster fibre has good DIMENSIONAL STABILITY, and is therefore multiplex in the carcass material of radial.But because the surface lacks active group, so the bonding existing problems of terylene and rubber, especially under hot conditions.Nylon fiber contains a large amount of amide groups, can form hydrogen bond with rubber, therefore has advantages of the bonding force high temperatures, and the nylon superior fatigue resistance, therefore can be used for the body piles of radial band and Bias tyre.But the nylon DIMENSIONAL STABILITY is relatively poor, and especially under hot conditions, modulus descends obviously.Aramid fiber has very high brute force and modulus, and the high temperature calculating modulus does not have to change substantially, but fatigue durability and bonding force can be used as the carcass material of tire not as nylon and terylene.
In order to give full play to the advantage of various fibers, avoid its shortcoming, often use mixed way of twisting with the fingers.In US 0265581, the mixed sth. made by twisting mode of introduction of authors be nylon fiber with low modulus as heart yarn, high modulus fibre is wrapped in around the heart yarn.Therefore in material extending, nylon is at first stressed, and stress strain curve is smooth, shows as low initial modulus, also begins stressedly after aramid fiber stretches, and modulus increases thereupon.After using the mixed sth. made by twisting mode of this wound form, stress strain curve has obvious yield point, can satisfy the different requirements of tire when making with use.In the time of most of, generally adopt the mixed sth. made by twisting mode (US 0090447, US 4155394 and US 6601378) of Split Down formula, two kinds of different materials twine mutually.The mechanical property of this compound cotton rope is between bi-material.。
Summary of the invention
The objective of the invention is: a kind of compound cotton rope that uses in tire is provided, it can effectively improve wash to bonding force.
The present invention is achieved in that a kind of compound cotton rope that uses in tire, comprise polyester thread and nylon wire, and the nylon wire spiral is entangled on the polyester thread; Its special character is: described polyester thread comprises the first polyester thread and the second polyester thread;
Described nylon wire comprises the first nylon wire and the second nylon wire;
The first nylon wire is spirally wound on and consists of the first strand on the first polyester thread, and the second nylon wire is spirally wound on and consists of the second strand on the second polyester thread;
The first strand and the second strand are mixed twist with the fingers after, the second polyester thread applying between adjacent two spiral the second nylon wires on the first polyester thread and the second strand between adjacent two spiral the first nylon wires on the First Line thigh.
A kind of compound cotton rope that uses in tire of the present invention, owing to adopting such structure, the compound cotton rope of this structure can take full advantage of the DIMENSIONAL STABILITY of bond properties and the terylene of nylon.Bonding force conservation rate behind the high temperature obviously is better than terylene, is similar to nylon; Use the tire of the mentioned cord of the present invention, its performance is far above national standard, and the durable and high speed performance of tire is better than general Polyester Cord.
Description of drawings
Fig. 1 is front view of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of compound cotton rope that uses in tire comprises polyester thread and nylon wire, and the nylon wire spiral is entangled on the polyester thread; Described terylene bar comprises the first polyester thread 11 and the second polyester thread 12;
Described nylon wire comprises the first nylon wire 21 and the second nylon wire 22;
The first nylon wire 21 is spirally wound on and consists of the first strand on the first polyester thread 11, and the second nylon 22 lines are spirally wound on and consist of the second strand on the second polyester thread 12;
Behind the mixed sth. made by twisting of the first strand and the second strand, first burst of upward the second polyester thread 12 applying between adjacent two spirals the second nylon wire 22 on the first polyester thread 11 and the second strand between adjacent two spirals the first nylon wire 21 of black horse.
Above-described only is preferential embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art, in the situation that do not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
