Definitions
- the present invention relates a system for industrial polyester yarn production, in which the mechanical properties of the yarn (tenacity, modulus, dimensional stability) are improved with additive, in order to be used in industrial fabric production.
- Liquid Crystal Polymers which can be used as reinforcing phase in different polymeric materials, are high performance resins with a unique structure comprising long, hard, rod like high oriented molecules. Rod-like molecules orient themselves in the flow direction during injection or extrusion molding.
- LCP The parts molded in LCP exhibit very high dimensional stability even if they are heated up to 200-250°C. Melting temperature of some LCP classes can reach up to 300°C. LCP can generally be used as an additive in many fields depending on its properties. Electronic and electrical components, fuel and gas barrier structures and sensors can be given as example for these fields.
- the objective of the present invention is to provide a system for liquid crystal polymer added industrial polyester yarn production.
- Another objective of the present invention is to provide a system for industrial yarn production wherein polyethylene naphthalate is used as polymer.
- a further objective of the present invention is to provide a system for industrial yarn production with improved tensile strength and elastic modulus.
- Figure 1 is the schematic view of the inventive system for yarn production.
- the inventive system for composite polyethylene naphthalate industrial yarn production system (1) essentially comprises
- the raw mixture forming unit (1) present in the inventive system (1) comprises
- PEN:LCP ratio of the mixture prepared in the raw particle loading unit (21) is 60:40 by weight.
- the raw material which is prepared in this ratio and solidified in cooling unit (23) melted and blended in the twin screw extruder (22) is become as particles.
- Primary mixture forming unit (3) comprises
- the raw mixture particles prepared in raw mixture forming unit (2) are sent to the primary molten forming unit (3), and the polymer particles diluted with pure PEN are produced here.
- the PEN:LCP raw mixture is mixed with PEN till the LCP ratio becomes 1-3% by weight in the particle loading and diluting unit (31). At the said process is preferably carried out at 260-300°C.
- the molecular weight of the blended polymer particles that are obtained are increased at the outlet of the primary mixture forming unit (3), and their internal viscosity (IV) is increased above 1 dL/g at 240-250°C with solid state polymerization, which takes 12-24 hours.
- IV internal viscosity
- the purpose here is to increase molecular weight to obtain a polymer suitable for yarn drawing by decreasing the degradation and chain movement during extrusion. %Crystallinity increase is above 100% with solid state polymerization.
- the particles obtained at primary mixture forming unit (3) with increased IV via solid state polymerization are dried in vacuum furnace for at least 24 hours at 120-140°C, and loaded to the primary particle loading unit (4) under nitrogen atmosphere at 120 °C.
- the humidity value of the blended and solid state polymerized particles should be under 60 ppm before loading to the extruder (32).
- the primary polymer mixture coming out of the primary mixture forming unit (3) is transferred to the primary particle loading unit (4), and dried here at 100-120 °C and sent to the extruder (5) which is heated to 290-320 °C.
- PEN-LCP polymer mixture comprising 1-3% LCP by weight is become filaments via spinneret at the exit of the extruder (5).
- the length/diameter ratio of the spinneret used at the extruder exit (5) is 2-5, the hole diameter is 1mm.
- the jet velocity of the material from the extruder (5) is 6-7 m/min, the residence time of the material in the extruder is 11-12 minutes.
- the throughput here is adjusted as 6-7 g/min.
- the PEN-LCP filament coming out of the extruder (5) is transferred to the cooling unit (6) preferably treated with cooling water.
- the length of the cooling unit is 70cm and its temperature is 80-95°C.
- the distance between the extruder (5) and the cooling unit (6) is adjusted as maximum 10cm.
- the yarn coming out of the cooling unit (6) first comes to the primary roller (71) and it is sent to the secondary roller (72) from here.
- the temperature of the primary roller (71) is between 100-140°C
- the temperature of the secondary roller (72) is between 140-160°C. Cold drawing process is applied on the yarn between these rollers (7).
- the yarn coming out of the secondary roller (72) is transferred to the first hot chamber (81) and heated with hot air to 200-250°C here and then transferred to the tertiary roller (73).
- the temperature of the tertiary roller (73) may vary between 200-250°C. Therefore, hot drawing is performed between the secondary roller (72) and the tertiary roller (73).
- the yarn coming out of the tertiary roller (73) enters into the second hot chamber (82) at temperature of 120-180°C. It comes to the quaternary roller (74) which is the last roller without heating, at room temperature; here it is relaxed in ratio of 1-2% and sent to the winding unit (9) in order to be wound.
- the ratio of the primary roller (71) speed to the extruder (5) exiting speed is between4-6.
- the ratio of the tertiary roller (73) speed to the primary roller (71) speed may vary between 5-6,5.
- the conversion ratio is in range of 80-90% when the monofilament yarn which is produced with the inventive system is twisted as 2 layers with 50 twists.
