    The invention relates to the technology of producing synthetic fibers, in particular polyester, which have valuable properties and have found application, for example, for reinforcing j tires.
    The purpose of the invention is to increase the breaking strength of the fiber.
    The processing of the fibers is carried out preferably under stress relieving conditions on a reel.
    The results of polyester fiber production in examples 1-10 are given in table. 1-10 respectively
    In the compounds shown in Table 1, the R groups are chloro-substituted (Au and B), bromo-substituted (C) and methyl-substituted (D and E) 1,4-phenylene rings obtained by chemically reacting the corresponding chloro, bromo - and methyl substituted 1,4-phenylene diacetate in equimolar proportions with the corresponding dicarboxylic acid having groups R.
    These compounds react in the usual way, for example, in a tube with a polymer melt having a side outlet, a tube with a nozzle for nitrogen or inert gas, a microconnector, a stirrer and a tube for collecting the distillate,
    According to Example 1A (Table 1), the reactor and its contents heat the nppi while simultaneously stirring, first at 283 ° C for one hour in the presence of anhydrous sodium acetate, which serves as a catalyst (the acetic acid by-products are distilled off), and then the same temperature for 10 minutes under reduced pressure of 0.2 mm Hg, and finally for 25 minutes under the same reduced pressure, after which the resulting anisotropic melt is cooled and a polymer having a true viscosity is extracted from it 3.4 (used zu 2 solvent), chemical Typically the reactants are stirred with a mechanical stirrer, especially in the first stage and / or by passing them through a nitrogen or inert gas and / or by passing the byproduct, which is formed and is distilled off from them under reduced pressure. Catalyst use is not a requirement

    It is also used only in Example 5. D is antimony trioxide (Table 5), and in Examples 8 and 10 A is sodium acetate (Tables 8 and 10, respectively).
    Heat treatment is carried out in the following ways; a) the yarn is suspended in a furnace with a tilted continuous flow of nitrogen, the furnace and the sample are heated according to the indicated temperature / time processing cycle; b) the yarn is wound on a perforated bobbin that is pre-coated with ceramic insulation wool to obtain a soft, heat-resistant surface that bends at low voltages, and then the bobbin with the wound yarn is placed in a furnace where the treatment is carried out according to the method (and ); c) The yarn is freely placed in a perforated basket, which is placed in an oven and processed according to method (a), or placed in a glass tube, which is heated with a certain temperature / time cycle with a continuous stream of nitrogen through elementary fibers.
    Temperature / time cycles are shown in Table 1-10. So, for example, in example IA (Pl. O the furnace and the sample is heated under nitrogen atmosphere for 1 hour, then heated at 230 ° C for 1 hour, then at 260 ° C for 2 hours and finally at 290 ° C for 3/4 h. Typically, the temperature changes so quickly that both the furnace and the sample are at the measured temperature almost completely for a specified time. Less rapid temperature changes are noted as follows: arrow, as in Example 1B (- -310 / 0.7) indicates that temperature changes occur less quickly, while the word is before (t) ; as in example 5C (150 to 160/5) indicates that the temperature is within a predetermined limit, tending to increase, and a dash, as in example 5A (235-265 / 1.5), shows that the temperature changes slowly for the first 10-30 minutes, and then for the rest of the specified period, remains higher. It should be noted that sometimes the furnace is cooled and then heated again, as

    in the example, FOR (Table 3), where T is the fiber strength strength, G / den; E - elongation,%; jW - modulus of elasticity, g / s / denier.
    In example I (Table 1), F is a homopolymer obtained from chlorine substituted 1,4-fensh diandiacetate in ethylene dioxy-bis- (2,6-dimethyl-4-benzoic acid).
    In example 7 (table, 7) B and C are copolymers consisting of mono- and dichloro-substituted 1,4-phenylene-dis radicals and p-carboxyphenoxyacetic acid (7B) and methylenedioxy-4, 4 -dibenzoic acid (7C). In Example 7B, good results were obtained using polyethers from dicarboxylic acid with one aromatic carboxyl group and one aliphatic carboxyl group, separated from the ring by a short chain (-OCH j-), i.e. the longest chain between the rings in this polymer is (-OCH-C-0). pain II Oh
    the core of which is the ether group. In Example 8D (Table 8), a thiol-oxygen ester comprising a radical derived from p-mercaptophenol, hydroxy-bis- (4-benzoic acid) and terephthalic acid,
    In Example 10 (Table 10), a copolymer containing 82 mol.% Of p-hydroxybenzoyl radicals and 18 mol.% Of hydroxy bis (1,4-phenylene oxyl) and terephthaloyl radicals is used, and this is a copolymer that is obtained by chemical the interaction of an acyloxyaromatic carboxylic acid with a group of compounds selected from derivatives of diatomic phenols and aromatic and / or cycloaliphatic diatomic phenols and aromatic and / or cycloaliphatic dicarboxylic acids. Conventional polymerization conditions are used.

    containing polyethylene terephthalate, both freshly drawn and highly elongated, does not increase the tensile strength during heat treatment at temperatures approaching the melting point. In fact, the tensile strength of the filament decreases with heating in both experiments described. This reduction in tensile strength occurs regardless of the fact that the molecular weight is increased, as can be seen from the higher true viscosity achieved by heat treatment of the elementary fibers.
    Experiment 1. Pryu from freshly spun polyethylene terephthalate with true viscosity (jr) 0.90, in which the tensile strength of the fiber is 1.2 g / denier, heated in an inverted Dewar vessel with a capacity of 1 liter, loosely corked glass wool , with passing a stream of dry nitrogen (nitrogen flow rate of about 18 l / min) under the following successive conditions: (nitrogen inlet temperature, vessel bottom) 0.5 h / 150 ° C; 0.5 h / 200 C; h / 230 ° C. The yoke is maintained at low tension, sufficient to prevent entanglement in the turbulent gas stream. The final temperature is slightly lower than the temperature causing interfiber fusion. The treated fiber (n = 1.64) is a filament with a tensile strength of filament of 0.98 g / denier.
    Experiment 2. A strand of highly elongated polyethylene terephthalate with a true viscosity of .0.89, in which the tensile strength of the elemental fiber is 9.5 g / denier, is heat treated in the same way as experiment I; The treated yarn, „1.38, has a tensile strength of elementary fiber of 4.7 g / denier.
