Description of the invention (1) The present invention relates to high-strength and high-elasticity synthetic fibers. In the advanced technology of processing synthetic fiber and its processing device, the advanced technology of crystalline dispersing fiber materials, such as polyethylene, can be manufactured after stretching at a temperature above the crystalline dispersion temperature with less molecular chain complexation. High-strength, high-elasticity fiber. Related to this method was published by Lemstra et al. Of DSM in the Netherlands in 1979. Its fibers were sold using Dammer (registered trademark) and Spectra (registered trademark) as merchandise. In this method, it is necessary to take out the molecular chain from the crystal without damaging the crystal, and it is indispensable to extend it above the crystal dispersion temperature. This method is a macromolecule observed with obvious crystalline dispersion temperature, such as polyethylene, polypropylene, polyvinyl alcohol, etc., which are very effective molecular chain alignment methods, but it is not suitable for fiber materials without obvious crystalline dispersion, that is, , Polyester, nylon, etc. In view of this, a method of arranging molecular chains that is prolonged instantaneously after the fibers are urgently heated and cooled and solidified is known, and a domain extension method or a domain extension / heat treatment method is known. The principle of this method is that after a large temperature gradient is generated in the fiber and then it is stretched at a high slope speed, the method of taking out the molecular chain, according to the speed of alignment crystallization, is relatively deformed at a large deformation speed. Those who are uniformly deformed at a high magnification. Therefore, if the obtained fiber has high strength and high elasticity in itself, the high-strength and high-elasticity fibers required for the advancement of multiple stages can be produced separately or with fewer extension steps than the prior art. After adopting this method, the raw material polymer does not depend on the inherent crystalline dispersion, etc. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page)- --Order --------- Printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 538156 A7 V. Description of the invention (2) Mutual transfer phenomenon, which depends on the direction of the fiber axis to form a large temperature gradient 'In principle, it does not depend on the polymer type. Therefore, starting from polyester and nylon, it can be applied to a variety of fiber materials. In the prior art 'synthetic polymer fiber manufacturing process, the fiber heating is controlled indirectly by controlling the atmospheric temperature in the heating zone of the contact heaters such as heating needles and heating rollers, or directly or non-contact heaters. Examples of heating atmospheres include air and steam. In these methods, the movement of heat is mainly carried out after the heat is transmitted through the fiber surface. Therefore, the heat transfer efficiency is poor and rapid heating is difficult. In addition, it is generally difficult to uniformly heat the surface of the fiber through heat transfer, especially when the temperature of the heating zone is set to a high temperature for the purpose of rapid heating, which causes a significant temperature difference in the cross section of the fiber, which easily leads to uneven deformation and uneven structure . Because rapid and uniform heating is not possible, the fiber deformation speed is significantly limited, making it difficult to perform high-speed field extension and heat treatment. In addition, Japanese Unexamined Patent Publication No. 4-2 8 1 0 11 and Japanese Unexamined Patent Publication No. 5-1 3 2 8 1 6 disclose methods for uniformly heating the filaments and not using thermal radiation, but using infrared radiation. Those who show a certain effect on the uniform heating of the thread. However, the difference between this and the prior technology is that the thermal movement mode is changed from heat conduction to heat radiation. The heating of the yarn uses a device of the same size as the previous heating cylinder. For the running direction and advance of the yarn, the heat treatment method The user is heating the same length. Therefore, the thermal energy added to the yarn per unit time is the same as that of the prior art. After the rapid heating, the advantages of the extended area extension and heat treatment method cannot be generated in a short time.

Polyester fibers of raw materials can be used in addition to polyester with ethyl terephthalate as the main repeating unit, and polymer with butyl terephthalate or tetramethylene terephthalate as the main repeating unit. Ester melt-spun fibers. The so-called polyester whose main repeating unit is ethyl terephthalate refers to polyester with terephthalic acid or its ester-forming derivative as the main acid component, and ethylene glycol as the main alcohol component. Here, it can also be a copolymer of an acid component or an alcohol component known in advance. Specific examples of the acid component are: isophthalic acid, naphthalenedicarboxylic acid, diphenyldicarboxylic acid, diphenylsulfonic acid, adipic acid, sebacic acid, 1, 4-cyclohexanedicarboxylic acid Dicarboxylic acids or their ester-forming derivatives, sodium 5-thioisophthalate, sodium 2-thioisophthalate, 1 '8-dicarboxynaphthalene-3, sodium sulfate, etc. Dicarboxylic acids or their ester-forming derivatives, or potassium and lithium salts of these compounds, and hydroxycarboxylic acids or their ester-forming properties such as p-acrylic acid and p- / 3-hydroxyethoxybenzoic acid Derivatives, etc. In addition, as specific examples of the alcohol component, such as lower alkylene glycols such as propylene glycol and butanediol, 1,4-cyclohexanedimethanol, neopentyl, etc. The paper standards are applicable to China National Standard (CNS) A4 specifications ( 210 X 297 mm)-10- -------------------- Order --------- line (Please read the notes on the back before filling (This page) 538156 A7 B7 V. Description of the invention (8) Alcohol, 1,4-bis-hydroxyethoxy) benzene, bisglycol ether of bisphenol A, etc. Moreover, when the polyester is substantially linear, it may also contain polycarboxylic acids such as trimellitic acid, pyromellitic acid, etc., and polyalcohols such as pentaerythritol, trimethylolpropane, glycerol, or monohydrogen. Polymerization stoppers such as polyepoxide and phenyl acetate. The raw material of nylon fiber refers to a fiber that can be melt-spun nylon 6, nylon 6, 6, nylon 6, 10, and the like. It is also possible to copolymerize a previously known acid component or amine-based component. The raw material polyetherketone fiber refers to a fiber that can be melt-spun with the p-benzene and ether-based or ketone-based units as the main repeating unit. High-strength synthetic fibers obtained by drawing polyester fibers have an average refractive index of 1.58 to 1.69 and a birefringence of 0. 16 to 0. 24. The average refractive index can be converted into a parameter of the density of the polyester fiber, and the parameter of the birefringence is the parameter of the molecular orientation of the polyester fiber. In addition, a polyester high-strength synthetic fiber having a strength of 0.85 to 3 GPa, an initial elasticity ratio of 18 to 40 GPa, and a boiling water shrinkage ratio of 4% or less. Generally, the higher the viscosity number and the larger the molecular weight of the polyester fiber, the higher the strength is. Conversely, the synthesis and processing of fibers with large viscosity numbers are prone to difficulties, and the cost is not conceivable. The high-strength fiber of the present invention shows the strength and elasticity even if the viscosity number is 0 to 0 · 6 5 d 1 / g. The processing method of the present invention is shown in FIG. 1. The yarn 10 is supplied to the yarn 1 at a constant supply speed V by a roller 10, and the infrared rays containing the laser are irradiated. 13 After the infrared beam is irradiated to the yarn 1, the yarn 1 is heated to It will soften after the glass transition temperature is higher than the supply speed.

Description of the Invention (9) After the thread 1 is stretched. As shown in FIG. 2, after the molten polymer of the synthetic fiber raw material is extruded from the melt spinning nozzle 5 and cooled to a temperature below the glass transition temperature, the solidified filament 1 is rotated to hold the drum 6.6 to After the speed V is extracted and sent out, the yarn is softened by the infrared irradiation method 13, and the yarn 1 may be taken up by the drum 11 at a faster speed V than the supply speed V, and then the yarn may be stretched. Irradiate the travelling direction of the travelling thread in the range of 0.1 to 100 mm. After the external beam is rapidly heated, the thread 1 is heated rapidly to increase the fiber temperature within this interval by 20 to 3 〇 K and then soften and extend. This result is contained in the heating area by extending most of the positive bias, typically 5.0% or more. The unstretched fibers that are not crystallized are near or above the glass transition temperature, and those with high crystallinity are near or above the melting temperature of crystals. A filament that is heated instantaneously can be extended by an external force to make molecules After the chain height is aligned, a fiber with high strength and high elasticity is obtained. The fiber structure formed in polyester, nylon, and polyetherketone, especially the integrity of the crystal, is affected by the elongation temperature. Therefore, after the elongation temperature is gradually increased, the multi-stage extension can achieve higher strength and high elasticity. fiber. In this case, the molecular chain can also be suppressed from being relaxed by the instant heating and extension. In addition, the main extension is from the roller 10 to the infrared irradiation method 13 as shown in FIG. 1 before the heating field, or from the rollers 6 and 6 to the infrared irradiation method 13 as shown in FIG. 2 below the glass transition temperature. The preheating does not limit its heating width, heating method, and it can be any of contact conduction heating, radiation heating, and convection heating. ---- ί ---- 1 ------------- t --------- (Please read the notes on the back before filling this page) This paper size applies China National Standard (CNS) A4 (210 X 297 mm) 538156 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (10) High-strength synthetic fibers are synthetic fibers obtained by melt spinning The wires and strips are irradiated with an infrared beam and then heated and softened after being traversed. After being stretched by an external force, they are obtained by winding processing. In addition, the filament is not limited to a single fiber, it can also be a bundle of multiple fibers. 0 As a light source for infrared beams, the synthetic fiber filaments absorb and soften and emit infrared wavelengths. 0 · 7 // m ~ 1 0 0 // m, specifically, such as a continuous spectrum light source using a high-temperature heating element, a coherent light source using laser oscillation, the laser light has high parallelism, so it is easy to form a concentrated light, a parallel light beam, and a person with a large output power is extremely ideal. In the laser, gas, solid, semiconductor, pigment, excimer, free electron can be used as the release source, and the vibration wavelength of carbon dioxide gas as the release source is 9 ~ 1 2 // m, in order to add a trace amount N d 3 + yttrium aluminum garnet red (3 Y 2 0 3 • 5 A 2 0 3) is a vibration source with a release wavelength of 0.9 · 1 · 2 // m is particularly desirable. Among them, carbon dioxide lasers are effective in those whose synthetic fiber materials such as polyester, nylon, and polyetherketone exhibit strong absorption wavelength bands. The vibration method is preferably continuous vibration, and pulse vibration may be used as long as the frequency is sufficiently high. For example, when the travel speed of the thread is 50 m per second and the length of the irradiation field is 10 m m, a continuous wave with a cycle number of 100 k Η z or more and intermittent vibration can be used. The infrared energy of the absorbing filament depends on the infrared wavelength, and the diameter, filament speed, density, heat capacity, and infrared absorption rate of the filament. When the temperature rises by △ T after irradiating with infrared rays, it can be assumed that the filament walking behavior is constant I ------ ^ ------------- order ----- (please Please read the notes on the back before filling this page) Line #-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -13- 538156 Printed by the Intellectual Property Bureau Staff Consumer Cooperatives of the Ministry of Economic Affairs Α7 Β7 5 Description of the invention (at the state of ιυ, it generally shows a relationship of △ τ 2 Q / WC. Among them, Q is the energy absorbed by the filament in unit time after irradiation, W is the mass flow of the filament, and C is The specific heat of the yarn. Infrared energy per unit time irradiated by the yarn can be used as i 'then Q-K i' wei 'K is the absorption rate of the infrared energy of the yarn. As a typical condition, K is assumed. 2 · 3, wire diameter 0 · 1 mm, wire speed 5 m / s, specific heat 1 · 17 kJ / kg · K, density 1 · 32Mg / m3, then ΔT 2 5 1. That is, on the thread When irradiated with 1 W of infrared light, the temperature of the filament only increased by 5 Kelvin (ke 1 vi η). Therefore, under this condition, the filament was illuminated by the infrared light beam within a 10 mm interval. If only 50 Kelvin is heated rapidly, the sliver must be irradiated with an infrared beam with an average intensity of 10 M w / m 2. Moreover, the temperature of the sliver is also increased by the deformation of the fiber itself. Therefore, When the fiber heated to the vicinity of the glass transition temperature is softened and stretched, the heat generated by the viscous or plastic deformation increases the temperature and produces a softening chain change, which can concentrate the deformation in a very narrow range. The infrared irradiation field of the present invention refers to a range where the intensity of the infrared beam irradiated on the thread and the intensity at the maximum position in the thread are in a range of 1 / e 2 or more. However, e is the bottom of the natural logarithm. In addition, after the filament is heated and softened, when the fiber is stretched, the amplitude of the vibration of the fiber axis is 10 to 1000 // m, and the frequency of the cycle is 100 to 100000 k k. The fiber processing device of the present invention is shown in Fig. 1. The method of continuously supplying yarn 1 at a certain speed V is 10 and faster than the certain supply speed V.

In the example in FIG. 5, the infrared IR by the infrared irradiation method 13 is focused by the lens 16, and the infrared IR that is not absorbed by the filament 1 is reflected by the concave mirror 17 and then focused on the filament Return after 1.

Description of the invention (13) In the example ' Furthermore, after the optical axis of the infrared irradiation method 13 is tilted by the wire 1 in the vertical direction, the infrared IR irradiation field becomes a long oval in the direction of the wire 1 and the infrared IR is irradiated in the vertical direction. The area S b is slightly larger than that of the yarn 1, and the direction of travel is such that the irradiation area S a of the infrared IR is condensed in the range of the softened yarn 1 and effective use of infrared energy is performed. In the example of FIG. 6, the infrared irradiation method 13 causes the optical axis to be deflected, and the lens 16 is used to condense the infrared IR of the laser 15 and the infrared IR not absorbed by the filament 1 is reflected by the concave mirror After that, it focused on the thread 1 and returned. Since the optical axis of the lens 16 is deflected, it is the same as the example in FIG. 5, so that the irradiated area of the infrared IR can have a vertically long ellipse in the direction of travel of the filament 1. In the example shown in FIG. 7, in the infrared irradiation method 13, the red outer line IR from the laser 15 is introduced into the rotating inner surface reflecting mirror 17 through the optical fiber 19 of the waveguide. When the exit end of the optical fiber 19 is at the first focus of the spheroid and the extension of the filament 1 is positioned near the second focus, the filament 1 can be effectively heated. In the example of FIG. 8, the infrared irradiation method 13 causes the red outer line IR from the laser 15 to be introduced into the rotating elliptical inner surface mirror 17 through the lens 16. The focal point of the lens 16 is set to the first focal point of the spheroid, and the extension of the yarn 1 is positioned near the second focal point. In the example of Fig. 9, the infrared irradiation method 13 causes the red outer line IR from the laser 15 to be introduced into the elliptical cylindrical inner surface mirror 17 through the cylindrical lens 16. The focal line of the cylindrical lens 16 is inside the elliptical cylindrical internal mirror I U ---- 1 ------------- ^ --------- (Please read the back first Please fill in this page for the matters needing attention) This paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) -16- Printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs 538156 A7-B7 V. Description of the invention ( 14) The first focal line of 7 and the extension of the yarn 1 are positioned near the second focal line. Therefore, the infrared rays IR of the running direction of the filament 1 are lenticular and non-concave. The vertical direction is the lens function of the cylindrical lens 16 and the concave mirror of the internal mirror 17 of the elliptical cylinder, and the infrared IR is focused. It is advisable that the running direction of the yarn 1 becomes longer and the whole area is irradiated with infrared IR. In the example shown in Fig. 10, the infrared irradiation method 13 causes the infrared rays IR from the laser 15 to irradiate the filament 1 through the wide waveguide 19. The guided wave path 19 has a single entrance port in the laser beam 15 and a plurality of layers of exit ports are overlapped in the running direction of the wire strand 1 toward the wire strand 1. Therefore, the running direction of the yarn 1 is vertically irradiated to its infrared IR, but the running direction only illuminates the separate width portion of the waveguide 19, and can be effectively heated. As the material of the lens 16, 6, 18, the waveguide 19, or the reflector 17, it is necessary to be a material that transmits or reflects infrared rays. As an example of the former, the wavelength is 9 ~ 1 2 // m such as: zinc selenide, silicon, germanium, chalcogen glass, etc., and the wavelength is 0.9 ~ 1.2. 2 // m such as; quartz, Examples include lithium fluoride, barium fluoride, and fluoride glass. Examples of the latter are: metal mirrors. It is also possible to use a reflective tube hollow tube attached to the inner surface as the waveguide 19.

The intensity and The test of elongation and initial modulus of elasticity is a uniaxial tension test at a speed of 0.67 mm per second after holding the fiber sample reinforced with paper and adhesive at the initial unidirectional interval of 40 mm. The nominal stress and nominal deviation read from the obtained stress-deviation curve are calculated after use. The initial modulus of elasticity is determined by the deviation, strength, and elongation of the zero point from the stress and deviation of the cut-off point.

Compared with the general area extension, this speed is the production speed. About 1 Times less than the transformation temperature of the swash large degree by 10 times. The mechanical properties of the obtained high-strength synthetic fiber were extended to 7 times under the same elongation conditions. Comparing with the sample j of Comparative Example 3, the strength reached 3 · 2 times and the initial elasticity reached 4 · 5 times. After the 7-stage and 2-stage elongation were also compared with the sample of Comparative Example 4, the strength also increased by 1.08 times, the initial elasticity increased by 1.07 times, and the elongation increased by 1.25 times. [Example 2] Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. The yarn of the same fiber as in Example 1 was heated by infrared rays under the conditions shown in Table 1 and then extended. As a result, the strength of the high-strength synthetic fiber increased by 3.5 times and the initial modulus of elasticity increased by 5 · 2. In addition, when the second stage, which also extends to 7 times, is compared with the sample fiber of Comparative Example 4, its strength is also increased by 1.17 times, the initial elastic modulus is increased by 丄 · 21, and the degree of elongation is increased by 1. · 6 3 times. . [Example 3] The filaments of the same fibers as in Example 1 were stretched after being heated by infrared rays under the conditions of Table 1 and the high-strength synthetic fibers obtained were compared with the fibers of the sample of Comparative Example 3 which were stretched to 7 times under ordinary stretching conditions After that, it will not only be extended 21 times, this paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 public love) 538156 Printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of invention (19) The rate is 6 times Those with low ridges, strengths of 2 · 7 times, and initial elastic modulus of 4 · 2 times. After comparing the sample of the two-stage comparative example 4 that is extended to 7 times, the extension ratio is not only lower than 6 times, the initial elasticity rate is the same, and the strength is 0.91 times slightly less, but the elongation is But it has doubled. Large elongation means that there is no room for improvement in strength and elasticity after extension. [Example 4] The high-strength synthetic fiber obtained from the yarn of the same fiber as in Example 1 was stretched again by infrared heating under the conditions shown in Table 1. As a result, after comparing the sample of the two-stage comparative example 4 which was stretched to 7 times under ordinary stretching conditions, the stretch ratio was not only slightly reduced, the strength was 1.1 times, and the initial elastic modulus was 1.07 times. Also, fibers with a double extension were still obtained. As a result, when compared with Example 3, the strength was increased by 1.2 times, the initial elastic rate was increased by 1.0 times, and the elongation was maintained almost the same. This proves that after the infrared beam is irradiated, after rapid heating, the high-strength synthetic fiber made after high-rate stretching can further increase the strength and initial elasticity after stretching. [Example 5] The filaments of the same fibers as in Example 1 were stretched after being heated by infrared rays under the conditions shown in Table 1. The birefringence of the high-strength synthetic fiber is 0 · 16. It can be proved that the molecular chain is highly aligned.

Description of the invention (20) The position of the optical axis of the carbon dioxide laser Is the distance from the origin to the direction of travel of the yarn, and the vertical axis is the yarn speed. Centering on each point in the range of ± 1 · 5 mm is equivalent to the most frequent silk speed of 3 seconds. ◦Represents the measurement results of the yarn supply speed and the winding speed of the yarn in Example 5. The solid line represents the intensity distribution of the intensity-normalized laser beam at the center. The wire speed is that the yarn is suddenly jumped from the feed speed to the winding speed at a position about 1 mm in front of the optical axis of the carbon dioxide gas laser. This not only represents a drastic change in diameter that causes a constriction, but also means that the extension start point and end point of the extension are at most 1 mm m. The extension start point starts from the origin and the extension end point also contains the laser irradiation range, so it is a typical area extender. This extension condition is close to those of Examples 1 to 3. Therefore, it can be determined that Examples 1 to 3 will also cause typical area extenders. [Examples 6 and 7] The yarns of the same fibers as in Example 1 were heated by infrared rays under the conditions shown in Table 1 and then stretched. Compared with the two-stage comparative example 5 sample which has been extended to 6 times, the initial elastic modulus is 1.38 times, the strength is 1.31 times, and the elongation is 1.46 times. [Example 8] The sample of Example 7 was finished (stretching was completed). The sample was subjected to heat treatment at 160 ° C for 1 hour and under a low tension.

Description of Invention (21) [Example 9] The sample of Example 7 (Completed Elongation) Heat treatment at 240 ° C for 3 hours at 90% of the maximum shrinkage stress. Compared with the low-tension heat treatment, the strength and initial elasticity are improved. [Example 1 0] A polyester filament having a viscosity number of 0.93 5 g / d 1 was used as a raw material, and the fiber filament was stretched by infrared heating under the conditions shown in Table 1. The viscosity number of the obtained fiber was 0 · 8 7 d 1 / g. A polymer with a high viscosity number can be used to obtain polyester fibers with higher strength. [Example 1 1] The sample (complete extension) of Example 10 was subjected to heat treatment at 240 ° C for 3 hours under a stress state of 90% of the maximum shrinkage stress. In addition, its strength and elastic modulus were further improved than in Example 10. For the samples obtained in Examples 6 to 11, the boiling water shrinkage and crystal orientation, which are important for practical use, were measured. ◦ The heat shrinkage of boiling water in Examples 8, 9, and 11 was reduced to about 1% after heat treatment. Those polyester wood chips with a viscosity number that is not so high can still obtain extremely high-strength, high-elasticity fibers, which is not only advantageous in terms of manufacturing cost, but also allows the reduction of physical properties after the use of recycled materials.

Description of the invention (22) Extended by infrared heating under the conditions in Table 1. This condition is lower than the supply speed of Example 5, and the laser light energy irradiated by the traveling fiber is increased. Therefore, the temperature of the yarn is higher than that of Example 5. The obtained polyester fiber has a low orientation, and the initial elastic modulus and strength also become small. The silk velocity distribution under this condition is shown in Figure 1 Γ. The position of the optical axis beyond 5 mm by the wire speed is still only about 50% of the total positive deviation. The deformation is not complete. The obtained polyester fiber is a low-alignment type, and is a typical flow extender. The so-called flow extension refers to the extended form that occurs when the polymer is extended at a temperature higher than the glass transition temperature. Generally, the molecular orientation is not too large, and the initial elasticity and strength become small. The average refractive index of Examples 1 to 3 is almost the same as that of Comparative Examples 4 and 5. The so-called Lorenz Lorenz formula is usually established between the average refractive index and the density. According to the relationship between the average refractive index and the density of polyethylene terephthalate, the average refractive index 1 · 60 is equivalent to the fiber density 1 · 3 8 7 g / cm 3.

The elongation temperatures of Comparative Examples 4 and 5 are set at the lowest temperature at which the set elongation can be performed. Therefore, almost the maximum molecular orientation can be obtained under the respective conditions. Foreseeable, mechanical properties Also the largest. Taking the same common elongation conditions for each raw material fiber as another experiment, after testing various elongation ratios and yarn supply speeds, stable elongation was measured to obtain high-strength, high-elasticity fiber conditions. The results are shown in Figure 12. In the figure, X represents no extension condition, and △ represents extensibility. However, the width of the range of the extension point is greater than 0 · 2 mm. _ And 〇 represent the extension range of the position within the width of 0 · 2 mm. Lu Wei extended the fiber's birefringence to above 0.160, and obtained high-strength and high-elasticity fibers. When the stretch ratio is less than 5 times, the area that can be stably extended is that the higher the stretch ratio is, the more the yarn supply speed is moved, and when the stretch ratio is 5 times or more, the stable stretch area is the higher the stretch ratio The supply speed moves higher. In addition, when the stretching ratio is 5 times or more, the refraction of the fiber after stretching is 0. 160 or more, and the crystal orientation is 0.98 or more. It can be straight-fee'd or multi-stage stretched, and high-strength synthesis can be obtained after heat treatment. fiber. Therefore, a 'stretching ratio of 5 times or more is highly desirable. r --- * ------------- t --------- ^ ^ (Please read the precautions on the reverse side before filling out this page) ^ The paper size applies Chinese national standards (CNS) A4 specification (210 X 297 mm) ㉝ 538156 Member of the Intellectual Property Bureau of the Ministry of Economic Affairs Η Printed by the Consumer Cooperative A7 B7 i. Description of the invention (24) However, 'The stretch magnification of this high-strength synthetic fiber is based on the birefringence of the fiber before extension Different. When the birefringence of the pre-stretched fiber is 0 to 0 · 0 05 ′, as described above, a high-strength synthetic fiber can be obtained by stretching at a stretching ratio of 5 to 10 times. Similarly, the birefringence of the fiber before stretching is 0 ~ 005 ~ 0 · 10, and the birefringence of the fiber is 4 ~ 7 times, and the birefringence of the fiber before stretching is 0 ~ 〇i〇 ~ 〇 · 〇2 at 3 ~ When the stretching ratio of 6 times and the birefringence of the fibers before stretching are 0 · 0 2 0 to 0 · 2 0 0, they are stretched at a stretching ratio of 1 · 8 to 5 times to obtain high-strength synthetic fibers. [Industrial Applicability] The high-strength synthetic fiber of the present invention has higher strength and elasticity than the high-strength synthetic fiber that preceded it. When the synthetic fiber with high strength and tube elasticity is processed in the prior art, There are many steps, and the processing method of the high-strength synthetic fiber of the present invention can effectively process extremely high-strength and high elasticity even if a raw material polymer with a low viscosity number is used, and can mass-produce the cheap synthetic fiber. In addition, the high-strength synthetic fiber processing device is not only simple in construction, but also saves heating energy, and can be used as a processing device for high-strength synthetic fibers.丨 ί — 丨 卜 丨 丨 by -------- Order --------- line # · (Please read the precautions on the back before filling out this page) This paper size applies to Chinese national standards ( CNS) A4 size (210 X 297 mm) -27-
