[Previous technology] Polyester fibers have the most excellent mechanical properties, dyeability, and low cost, so they are most commonly used among the three major synthetic fibers. The process of polyester fiber is roughly as follows: p-diphenylarsinic acid and ethylene glycol undergo a polycondensation reaction to produce polyester pellets or melts. After being extruded and measured by melt extrusion, they are cooled, oiled, and coiled. The cooling effect in this process has a considerable impact on the physical properties and uniformity of the silk. At present, the commonly used cooling method is the cross flow qUenching system, as shown in Figure 1. The radiation type internal blowing device (Radial 〇ut—10—in fl0w quenching system) is shown in FIG. 2. The radiation type external blowing device (ιη-to-out flow quenching system) is shown in FIG. The explanations are as follows: In the horizontal blower system, after the tow is ejected from the spinneret, the cooling air is cooled by the wire unilaterally cooling the tow ', and in the wheel-type internal blowing system, after the filament is ejected from the spinneret, the blower pipe Inside, the cooling air cools the tow from the surroundings; while in the radiation-type external blowing system, the filaments are ejected from the spinneret and then passed through the blower tube, and the cooling wind cools the tow from the surroundings. At present, the three types of blowing methods are most commonly used in horizontal blowing, while the radiation type internal blowing device and the lucky animal shooting type external blowing device are more commonly used in staple fiber (Staple), and a small part is used for industrial yarn production. Although 1221488 polyester fiber has many advantages, it lacks the advantages of softness and thermal insulation of natural cotton and wool fibers. For this reason, fine denier polyester hollow fiber was born. It has a fine and delicate feel, which is not as thick as ordinary thick denim hollow yarn, and also has lightweight thermal insulation properties. The fine denier hollow pre-stretched yarn prepared by the method of the present invention is cooled and blown during melt spinning, and adopts a radiation-type external blowing method. The single-fiber denier is 0.3 to 2.5d with uniformity and long period variation (u % l / 2inert) is less than 0.3 ° / ◦, the thermal stress variation between the spindles is less than 4%, and the hollowness is between 25 and 40%. After the extension processing, such as stretch twisting, air blow twisting, etc., the single fiber denier is obtained. Polyester fine denier hollow yarn with 2 to l.Od, 25 to 40% hollowness, and excellent dyeability. [Summary of the Invention] The problem to be solved by the invention is to use polyester hollow yarn to make fabrics and clothing for lightweight insulation purposes. It has been widely circulated on the market. The texture is rough and the cloth surface is prone to tendons due to uneven cooling. The use range is limited. In order to achieve light weight insulation and have both soft characteristics, we can start by reducing the single fiber denier and increase the hollow ratio. However, there are two ways to reduce the single fiber denier. This is achieved by increasing the number of orifices of the spinneret or the number of orifices of the spinneret and reducing the total amount of polyester melt. Poly-S purpose long-fiber melt-spinning cooling and blowing method, most of which are mainly horizontal type blowing and a few corrective blowing methods. When the ship has a fine Danny ^ _ _ melt-spinning cooling and blowing method, money correction The turning type is mainly used as a horizontal-type cooling device. Because the tow is exposed to wind on one side, the difference between the tow and the leeward cooling of the tow is large, and the tow cannot be cooled uniformly, especially the ejection of the spinneret. When the number of holes is increased, the cooling difference increases; 7 1221488 When the spinneret ejects pure scales, the number of monofilaments (storage) is increased, but the number of people is insufficient, and the required hollowness and hollow average sentence cannot be obtained. Another method is to reduce the total spit of the dazzling melt, but the scale often causes a reduction in the output. This is because of the difference in physical properties of the two-strand yarn, which can cause dyeing blue. ", Gamma recording, because the cooling is difficult to touch, the wind speed is too small to achieve sufficient cooling of the tow 'causes uniformity and long-period variability ⑽ / increases the high, even more serious, the monofilaments adhere to each other and cannot Smooth spinning; the wind speed is too high, and the opposite direction of the direction of the wind ~ the wind interfering with each other causes the tow to be unstable and cause uniaxial collisions, the production condition is not good, and the tow is not narrow and the narrow cooling air duct, operability Poor, it is not conducive to the production of fine denier hollow yarn. Therefore, how to reduce the single-fiber denier and increase the hollow ratio without sacrificing the output, that is to become the outline of Ju Caizhong's manufacturing industry's breakthrough, Yuguo Patent No. 'γ, Shu, 859, and European Patent No. G_Qing number 2. In the US Patent No. & Deletion No., there is no detailed outline of the age, but the way to turn windless county is between 2⑽ to (12χ'single fiber Danny) cm 'because the length of the windless belt is too long and cannot be expected Hollowness and uniformity; and the hollowness of its products is at least following, which is quite different from the expected hollowness of 25 to 鄕. In European Patent No. 0_523A2, the cooling method 'the length of the airless belt is preferably 10mm to 30cm, the length of the air blowing in the quick cooling zone is 80mm to 12Gmm, and the length of the second slow cooling zone is 15 () 111111 to 35〇brain. Its production. σ Hollowness 4G ° /. To 8G%, it emphasizes that it has the characteristics of no deformation after being processed. As for the light-shooting type, as described in US Patent No. 5, 157, and US Patent No. 5, 866, 055, it is used to produce monofilament denier h α22. 1221488 does not disclose a method for producing fine denier polyester hollow yarn. In view of this, the inventors have carefully reviewed the previous process conditions and cooling equipment, and found that for a specific inherent viscosity and melting point of the polymer of polyacetic acid, a set (outer ring straight & And the inner ring is set to $ 20mm) After the multiple circularly arranged spinnerets are uniformly ejected, they are cooled by a cooling cooling tube that is blown by an outer line and < Even the completion of the present invention can increase the number of sheets that can be produced per unit area of the board, increase the degree of product, the distribution of single-spaced towels, decrease the denier of single fiber, and the product has excellent dyeability. Summary of the Invention The purpose is to provide a method for manufacturing a plurality of fine denier polyester hollow pre-stretched yarns, which have a viscosity (IV) of 0.5 to 0.7 and a melting point of 245 to 265 t: The polyester polymer is heated and melted and filtered to quantitatively extrude a plurality of fine denier polyester hollow pre-stretched yarns, which are characterized by: a. Passing the quantitatively extruded polyester melt through a multiple ring The ejection holes of the spinnerets (shown in Figure 5) are arranged uniformly. Out of the tow, and the ejection holes of the spinneret with multiple annular arrangements are arranged as the outermost diameter (D2) and the innermost diameter (Dl) mm; b. The ejected tow is below the spinneret Passing a wind-free zone with a length (Ls) of mm and passing through a circular cooling duct with a diameter (DO) surface and a length of Lq cm, the 9 1221488 cooling duct provides a cooling air blown from the inside out. Applying a cooling air with a wind speed of 0.2 to 0.6 m / s on the outside of the circular cooling duct to uniformly cool the tow below the polyester polymer glass transition point (Tg) and bundle it; c · Among them, D2, Di, D0, Ls, and Lq must satisfy the following formulas: (i) D2-Di ^ 20 (mm); (ii) 12 ^ Di ~ D〇 ^ 33 (mm); (iii) 2 $ Ls $ 8060 x total output (g / min) + number of squares, (mm), with 2SLsg20 (mm) as the best embodiment; (iv) 15 ^ Lq ^ 40 (cm); d. 1800 to 4000 The meter / minute is wound by the aforementioned tow. Another object of the present invention is to provide a radiation type external blowing cooling device to produce polyester fine denier hollow filaments, which can make the silk handle treacherous, and obtain uniform polyester fine denier hollow pre-stretched filaments and spinnerets. The length of the windless belt below the board is preferably 2 to (8060 × the output amount + the number of squares). The length of the windless belt is less than 2_si. The cooling wind will affect the surface temperature of the spinneret and make the production condition worse; no wind The length of the belt is greater than ⑽60 × the output volume is squared.), The long period variation (u% l / 2inert) of the average sentence degree becomes larger, and even if the wind speed is increased, the expected hollowness is 25 to 40% and uniform. The degree of long-period variation (1 / 2inert) is less than 0.3% of the pre-stretched yarn requirements, and the finished product is poorly dyed after stretching, and the weaving fabric (styling abiHty) has streaks. The arrangement of the ejection holes of the spinneret used in the method of the present invention (as shown in Figure 5), the difference between the diameter of the innermost layer (Dl) and the diameter of the outermost layer is set to D2K20mm. If the difference in the value of '10 D2—Di is greater than 20 mm, the difference between the inner and outer layer tows is too large, and the difference in hollow ratio and physical properties between the individual filaments in the tow is large, and a product with excellent dyeability cannot be obtained. The difference between the innermost layer diameter Di and the blower tube diameter Dg is between 12 and 33mm, and the value of Di-Dg is less than 12mm. The tow easily touches the blower tube and breaks the filament, and cannot normally spin; the value of Di-D0 is greater than 33. In the case of legs, the cooling efficiency of the blower is reduced, and the outer diameter of the spinneret (the tow at the DO is low due to insufficient cooling and the wire is easy to break. To enable the tow to obtain proper cooling, the length of the blower tube used in the present invention 15 to 40cm is the best. When the length of the blower tube is less than 15cm, the tow will break due to insufficient cooling, which will cause the wire to stick. When the length of the blower tube is more than 40cm, it will easily form turbulence and cause long-term variation of uniformity. l / 2inert) becomes worse; the blower used in the present invention is cylindrical, and can be made of multilayer cellulose or multilayer metal mesh or metal sintered filter or ceramic sintered filter, or made of multilayer perforated plate. The holes are blown out from the radial direction from the inside to the outside uniformly to cool the tow. In the present invention, the cooling wind speed is from 0.2 m / s to 0.6 m / s is preferred; if the wind speed is less than 0.2 m / s In seconds, the cooling is insufficient, causing the wire to stick and break, and with uniformity The long-period variation (u% l / 2inert) becomes larger, and the hollowness becomes smaller; if the wind speed is greater than 0.6 m / s, the long-period variation of uniformity cannot be made smaller, and there is no significant benefit to the long-period variation of uniformity. And it is easy to cause the tow to be too cold and cause broken wires. The density (hole density) of the ejection holes adopted in the present invention in the spinneret arrangement area is 7 to 15 holes per square centimeter; the definition of the hole bifurcation is as shown in Figure 5. It is shown by dividing the number of spit holes between D2 and Di by 1) 2 and the area between D1, that is, the number of holes ③2 and ^ 1) χ4 / ττχ (, D,). When the pore density is less than 7 holes per square centimeter, due to the need to reduce the total output, the denier number of the single fiber of the present invention can be reached from 0.3 to 2.5 days. 15 holes per square centimeter, due to the close arrangement of the single fibers, the cooling difference between the single filaments is large, the uniformity and long period variation (u% l / 2inert) is large, and spinning cannot be stabilized. The polyester granules used in the present invention have an inherent viscosity (IV) of between 0.5 and 0.7. After melting, they are extruded from a hollow spinneret, and after spinning, they are cooled and oiled to obtain the polyester. Hollow pre-stretched wire. The obtained polyester hollow pre-stretched yarn had a break point elongation of 180%, a single fiber denier of 0.3 to 2.5d, and a hollowness of 25 to 40%. The uniformity long-period variation (u% 1 / 2inert) is less than 0.3%; the thermal stress variation between ingots is less than 4%. After further drawing, such as drawing and twisting, air blown drawing, or the so-called one-step direct spin drawing process (Spin draw) shown in Fig. 7, the single-fiber denier 0.2 to 10 (1, hollow Polyester fine denier hollow yarn with a degree of 25 to 40% and excellent dyeability.
