Prior Art Conveyor belts, chafers, membranes, and coating fabrics require a high-quality, durable structure with high mechanical properties. For such applications, processes that provide high modulus and dimensional stability without significantly increasing costs must be developed. Therefore, studies are being conducted in the field of producing additive-based PET yarns. Liquid crystal polymers (LCP) that can be used as additives in different fields are in the family of high-performance resins that have a unique structure having long, rigid, rod-like highly oriented molecules. Rod-like molecules are oriented in the flow direction during injection or extrusion molding. Parts molded from LCP exhibit very high dimensional stability even when heated up to 200-250 °C. The thermal bending temperature of some LCP grades can reach up to 3000 °C. LCP can generally be used as an additive material in many areas based on its basic properties. Examples of these areas are electronic and electrical components, fuel and gas barrier structures, and sensor wheels.

Another purpose of this invention is to realize a system for the production of industrial polyester yarn with high tensile strength and elastic modulus. Detailed Description of the Invention A system for the production of industrial polyester yarn realized to achieve the purpose of this invention is shown in the attached figures, these figures; Figure 1 - Schematic view of a system for the production of yarn subject to the invention.

First hot chamber 82. Secondary hot chamber 9. Winding unit The industrial polyester yarn production system which is the subject of the invention (1) in its most basic form; - at least one raw mixture formation unit (3) in which the raw polymer mixture is prepared - at least one main mixture formation unit (3) in which the main polymer mixture is obtained using the raw polymer, - at least one main particle loading unit (4) in which the polymer particles constituting the main mixture are filled and heated, - at least one extruder (5) in which the main polymer mixture obtained in the particle loading unit (4) is melted and turned into filament with the help of the spinneret located at its end, - at least one cooling unit in which the material coming out of the extruder (5) is cooled - at least one cylinder (7) in which the material is advanced in the flow direction, - at least one hot chamber (8) in which the material is heated - at least one winding unit (9) in which the material drawn by the help of cylinders (7) by being cooled and heated is wound into thread. The raw mixture formation unit (2) in the system (1) according to the invention comprises; - at least one primary particle loading unit (21) where polyethylene terephthalate (PET) and liquid crystal polymer (LCP) are loaded and mixed, - at least one raw melt extruder (22) where the raw mixture is melted and extruded, - at least one raw melt cooling unit (23) where the material exiting the raw melt extruder (22) is cooled. 9081.58 In the preferred embodiment of the system (1) according to the invention; the PET:LCP ratio of the mixture prepared in the primary particle loading unit (21) is 60:40 by weight. The material prepared in this ratio and passed through the twin screw extruder (22) and cooled in the cooling unit (23) is then turned into particles. The main mix forming unit (3); - at least one secondary particle loading unit (31) where the polymer particles coming from the raw mix formation unit (2) are mixed and diluted with PET, - at least one main melt extruder (32) where the main mix is melted and extruded, - at least one main melt cooling unit (33) where the material coming out of the main melt extruder (32) is cooled. The raw mix particles prepared in the raw mix formation unit (2) are sent to the main melt formation unit (3) where the production of polymer particles diluted with pure PET is carried out. At the end of the second particle loading (31), the PET-LCP raw mix is heated and the LCP ratio in the mix is determined by weight. In one embodiment of the invention; The molecular weights and intrinsic viscosities (IV) of the particles obtained at the exit of the main mix formation unit (3) are extracted in the solid state. The aim here is to increase the molecular weight by reducing degradation and chain mobility during extrusion and thus to prepare a polymer suitable for spinning and to ensure reaction control. An increase in crystallinity of over 1007% was observed with solid state polymerization. 9081.58 In one embodiment of the invention; the particles obtained at the exit of the main mix formation unit (3) and whose intrinsic viscosities have been increased by solid state polymerization are loaded into at least 24 main particle loading units (4). In order to prevent hydrolytic degradation, the moisture value of the main solution before being loaded into the extruder (32) must be below 60 ppm. The main polymer mixture exiting the main mix forming unit (3) is turned into particles and transmitted to the particle loading unit (4) and sent there. It is converted into filament by means of a spinneret (5). In the preferred embodiment of the invention; the length/diameter ratio of the spinneret used at the end of the extruder (5) is 2-5 and the hole diameter is '1 mm. The exit speed of the material from the extruder (5) is 6-7 m/min and the residence time of the material in the extruder is 1.1-12 minutes. The flow rate here is adjusted as 6-7 g/min. The PET-LCP filament exiting the extruder (5) is preferably transmitted to the cooling unit (6) which is treated with cooling water. In one embodiment of the invention; The cooling unit is 70 cm long and has a temperature of 50-800 C. In the same embodiment of the invention, the distance between the extruder (5) and the cooling unit (6) is set at a maximum of 10 cm. The monofilament exiting the cooling unit (6) first reaches the primary cylinder (71) and from there it is sent to the secondary cylinder (72). In the preferred embodiment of the invention, the temperature of the primary cylinder (71) is between 0°C and 90°C, and the temperature of the secondary cylinder (72) is between 90-1000 C. A cold drawing process is applied to the monofilament between these cylinders (7). The monofilament exiting the secondary cylinder (72) is transferred to the first hot chamber (81) and here it is heated to 170-220°C with hot air and transmitted to the tertiary cylinder (73). The temperature of the tertiary cylinder (73) can vary between 170-2200C. 9081.58 Thus, the hot drawing process is carried out between the secondary cylinder (72) and the tertiary cylinder (73). The monofilament leaving the tertiary cylinder (73) enters the second hot chamber (82) in the IZO-ISOOCS. After leaving the second hot chamber (82), it reaches the fourth cylinder (74), the last unheated cylinder at room temperature. Here, it is given a 1-2% relaxation and is sent to the winding unit (9) for winding. In the system in question (1), the drawability of PET-LCP yarns produced with 1-3% LCP addition increased by 9-13% compared to pure PET yarns, and the conversion percentage of elastic modulus was found to be 2 times higher when PET/LCP 99/1 monofilament was twisted with 50 twists.
