Description
Technical field
The invention belongs to tire manufacturing techniques field, more particularly, to a kind of terylene tyre cord, its preparation method and its
Application in cross-ply.
Background technology
At present, it is in tire to use synthetic fibers as carcass reinforcing material more, wherein with terylene, nylon, artificial silk and
Aramid fiber is most widely used；And in the cross-plies such as motorcycle, bicycle, all-terrain vehicle and agricultural vehicle, carcass enhancing
Material is basic based on nylon curtain line, and the using area that its reason is mainly motorcycle, bicycle and agricultural vehicle etc. is mostly
Road conditions are poor, more based on country road, hill path etc., it is desirable to which tire has good shock resistance.But nylon curtain line
The shortcomings of there is high hygroscopic, pre- shrinkage factor, poor dimensional stability, and easily there is the defect of flat spot in nylon enhancing tire.Wash
The features such as synthetic fibre cord fabric thread has low water absorption rate, good stability of the dimension, therefore it is used for the carcass material of meridian tyres for passenger cars.
Effect --- anti-impact of the nylon curtain line in the oblique wheel tire such as motorcycle, bicycle, all-terrain vehicle and agricultural vehicle
Hitting property is good, and impact resistance can be weighed with the energy of rupture of tire, be found by research, the work to break and tire of the cord fabric thread of nylon 6
Energy of rupture between there is linear approximate relationship, as shown in Figure 1.The work to break computational methods of cord fabric thread, as shown in Figure 2.Work as curtain
During the work to break increase of sub-line, the energy of rupture that tire is made of the cord fabric thread also increases, the impact resistance enhancing of tire, therefore can
Tire impact resistance is improved by improving the work to break of cord fabric thread.The work to break of cord fabric thread can be calculated by formula (1)：
W=∫ F*dL ... ... ... ... ... ... ... ... ... ... ... (1)
W-work to break, J；
F-ultimate strength, N；
Elongation under L-ultimate strength effect, m.
As can be seen here, the elongation under the higher effect with ultimate strength of the ultimate strength of cord fabric thread is longer, the fracture of cord fabric thread
Work(is bigger.
The intensity of cord fabric thread be cord fabric thread ultimate strength divided by cord fabric thread nominal fiber number business, formula (2) can be passed through
Calculate：
UTS=BS/LD ... ... ... ... ... ... ... ... ... ... ... ... (2)
The intensity of UTS-cord fabric thread, cN/dtex；
The ultimate strength of BS-cord fabric thread, N；
The nominal fiber number of LD-cord fabric thread, dtex.
The content of the invention
It is an object of the invention to provide a kind of preparation method of terylene tyre cord, the preparation method can effectively improve
The ultimate strength and elongation at break of conventional polyester cord fabric thread, so as to improve the impact resistance of terylene tyre cord；The present invention is also carried
Supply using terylene tyre cord made from the preparation method, the terylene tyre cord not only remains the excellent of conventional polyester cord fabric thread
Point, its work to break and fatigue performance, which also have, to improve a lot；The present invention still further provides the terylene tyre cord in oblique
Application in tire, has given full play to the advantage of terylene tyre cord, and combines the advantage of the good impact resistance of nylon curtain line, keeps away
Its shortcoming.
The technical solution adopted by the present invention is：
A kind of preparation method of terylene tyre cord, comprises the following steps：
(1) spinning technique flow：Section-drying-Screw Extrusion-melt distribution pipe-spinning manifold-spinning group

Lattice are 1300DX2)；Its dimensional stability (DSI) is compared with the dimensional stability (DSI) of nylon curtain line, is carried with very big
Height, precursor fiber number is the dimensional stability (DSI) of the nylon curtain line of 1260 daniers and 840 daniers respectively up to 15% (rule
Lattice are 1260DX2) and 16.4% (specification is 840DX2), precursor fiber number is used made from 1000 daniers and 1300 daniers
The DSI of the terylene tyre cord of the present invention is then respectively smaller than 11% (specification is 1300DX2) and 9.5% (specification is 1000DX2), can
To be compared favourably with nylon curtain line.In addition, the terylene tyre cord produced by the present invention, it processes curing temperature can be original
More than 10 DEG C are improved on the curing temperature of the cord fabric thread of nylon 6, at least reduces by 25% cure time, and can be without rear inflator
Sequence realizes the dimensionally stable of tire；The flat spot defect of nylon curtain line tire is can greatly improve, while the rolling resistance of its tire
Power reduces 7% than nylon curtain line tire, and its tire is riding and handling test result is also superior to nylon curtain line tire；Energy
It is enough not increase the enhanced cross-ply apparatus for production line of existing nylon curtain line and do not doing the bar of big adjustment to production technology
Under part, industrialization production is realized.
Application of the terylene tyre cord produced by the present invention in cross-ply, in motorcycle, bicycle, all-terrain vehicle
In the cross-ply such as agricultural vehicle, the advantage of terylene tyre cord is given full play to, with reference to the good impact resistance of nylon curtain line
Advantage, keeps away its shortcoming.

Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
In various modifications and improvement that case is made, the protection domain that claims of the present invention determination all should be fallen into.
