Патент Японии 48-17209, кл. 42 D11,1973.(54) METHOD FOR OBTAINING CORD THREADS 1.4.95-5.5, and nt Under tension at 300–350 ° C for 0.1–0.9 sec. The thread is pulled through various rotational speeds of the exhaust discs. The threading pattern is similar to that on torsion rods. Heating of the yi-yi in the course of drawing is carried out by a contactless convection-radiation method, for example, using IR rays, reflecting from the inner surface of a hollow elliptical cylinder, in one of which focuses a linear radiator is placed, and the thermal rays are focused along the line of motion of the thread, and Dependencies dt of the speed of movement of the thread, set a different temperature of the radiator i, therefore, I get a different temperature of 8 °; a healthy one, in the area of the passing thread. For example, pulling the thread CONDUCTED; in three stages.

The stretching of the thread is carried out in three stages. The air temperature in the passage zone of the thread through the stretching thread is TI - 400 ° C; TC 60C; TSH-500S. The temperature of the medium in the thermostabilization chamber. Stabilization time 0.6 sec. The total frequency of you was 1: 5.5. Kapron cord yarn of the average linear density of 187 dachshunds was obtained, the yarn is 9543 gs / tex; shrinkage Thus, the proposed method allows to obtain a strong cord thread with a strength of up to 9543 gf / tex with a slight shrinkage of 3 ± 1.5%, which increases the durability of automobile tires (throughput) by 75%. At the same time, the economic effect from the use of kapron cord with improved physicomechanical indicators in tires is 221760 RUB with 1 ton of product per 1 million km of mileage. The method of obtaining cord yarns of stretching freshly formed kapron yarns in several stages and thermal stabilization, characterized in that, in order to improve the physical and mechanical properties of the thread, the stretching is carried out in three stages, first at 380-420 0, then at 4pQ-480C -nrc; nfor ";„ "n, HP, ™. . .г,: ..нх - „„ so-, i6 ,, кл. a, az / e. , 79po 5 3.
