Because the physical properties of the island component yarn after dissolving the sea component are excellent, it can improve the quality of the fluffed yarn knitted fabric as the final product. [Previous technology] In the yarn knitting process of using the sea-island type composite fiber to prepare yarn knitting fabrics, ‘the knitting speed’ requires a local-quality yarn ’, especially the smoothness of the yarn. Furthermore, the processing process after manufacturing yarn knitted fabrics requires a large number of complicated steps, such as weight reduction, fluffing, dyeing, etc., so it is necessary to properly control the internal stress and heat shrinkage properties of the yarn. In particular, the heat shrinkage stress of each sea component and the internal structure of the island component of the sea-island type composite fiber is particularly important when preparing yarn knitted fabrics. The sea-island composite fiber is prepared by using an alkaline soluble polymer as a sea component, and a fiber-forming polymer as an island component, and combining the two components to weave to form an sea-island fiber. , Its preparation is mainly for the preparation of fine denier fibers. In other words, after the sea-island composite fiber is prepared, the sea-island composite fiber is treated with an alkaline solution to dissolve the sea component of the alkaline soluble polymer, so that a detailed iMJi dimension containing only the island component is obtained. In this way, the paper size of the fine fiber prepared from the sea-island type composite fiber is applicable to the Chinese national standard (CNs) A4 size (210x297 mm) (Please read the precautions on the back before filling in this page)

Description of the invention (2) Compared with the method of preparing the fine Si fiber by direct textile method, it is more beneficial to obtain The fine denier fiber has excellent usability in spinning and spinning. However, the former requires a process for spinning or weaving, and the final process uses an organic solution to dissolve and remove the marine polymer. Generally, when the sea-based polymer is used in the sea-island type composite fiber rayon of yarn weaving, it is mainly used an alkaline soluble polyester copolymer. The reason is that it can use alkaline solution to dissolve the sea component ’and reduce the weight. It is widely used in the process of reducing the weight of general polyester fiber. It does not require a special equipment, and the organic solution requires high recovery costs. If the island component is nylon, since the degree of penetration of the nylon by the alkaline solution is extremely low when the sea component is dissolved, the dissolution rate of the sea component is less important. However, if the island component is polyester, the island component will be infiltrated before the sea component is completely dissolved. This is because the polyester has a weak solubility in alkali, which makes the sea component have a lower dissolution rate. After dissolution, the physical properties of the yarn are greatly reduced and deteriorated. As a result, the fluffing property becomes poor, and it is difficult to give the final product the desired appearance and feel. On the other hand, if the dissolving speed of the sea component is fast, the above problems can be avoided, and the lye density, dissolution temperature and time can be reduced, so that the cost required for dissolution can be reduced and the yield can be increased. In order to increase the dissolution rate of the sea component ', it is necessary to increase the content of a copolymer compound. However, if the content of the copolymer compound is increased too much, then the sea component will become an amorphous polymer while improving the solubility, which does not have a fixed melting point but only a softening point, thus causing textile difficulties. .

Through-hanging 'presses a jet machine on a spinning machine during the textile manufacturing process' to make all the fibers flow, where the extruder has a lower flow rate and shear rate, and the spinner's flow rate And the shear rate is higher. The shear stress of this shear rate is called melting viscosity (MV), which changes due to polymer properties. However, regarding the sea-island composite fiber prepared by combining two or more polymers in combination with the textile, the melting viscosities of the sea ingredients are different from each other, so there is a difference between the shear stresses thereof, and the result affects the complex mouth. The formation state of the sea and island components of the fiber and the physical properties of the composite fiber. Therefore, in order to obtain the physical properties required for uniform sea and island cross-section formation for use, it is necessary to select polymers with appropriate melt viscosity sea and island composition. _ 9-I '; I HU1.I 1 * 1' I'ilt ITl U4, a〇c _ This paper size applies to China National Standard (CNS) A4 specification (210X297 mm), (Please read the notes on the back first (Fill in this page again) Order Printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs 512189 A7 • _ B7 91. 09.26 Amendment " " '' ~~ ** " ------- *----- V. Description of the invention (6) (Please read the notes on the back before filling out this page) Niu Chuangbei 7Η, about the product of weaving fabrics with wool yarns, in order to show the fine yarn fluffing properties, evening meaning and touch, Because the polymer used in the sea-island composite fiber must maintain relative viscosity properties, not its melt viscosity. _ ^ In the present invention, the difference [aMV9_] between the island component polymer and the sea component polymer when the shear rate is 9000 [Ι / s] is when the shear rate is 5000 [. 1 / s] The difference [aMV5⑽] is 20% to 70%. That is, the AMV 値 at the spinner position should be less than ΔΜν 値 at the extruder position. In other words, the difference in melting viscosity [△,] between the island component polymer and the sea component polymer due to the increase in the shear rate should decrease. Otherwise, because it is difficult to achieve a sufficient amount of ^ and the fluff fibers in the yarn woven fabric are tangled with each other, the directional property of the island component is reduced, and its knitting property is reduced. 'Φ. Please refer to the graph shown in Figure 4 of the present invention, which reveals the change of AMV when all variability increases. As shown in Fig. 4, it is confirmed that the difference in melting viscosity between the island composition and the sea composition decreases gradually as the shear rate increases. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The melt viscosity of the sea component [MVS] is preferably less than the melt viscosity of the island component [MVi] when the shear rate is 500 to 9,000 [Ι / s]. ] [MVsSMVi]. The graph in Figure 3 reveals the correction between melt viscosity and shear rate of each component. If the melt viscosity [MVS] of the sea component is greater than the melt viscosity [MVi] of the island component polymer, the cross section of the sea-island fiber will be difficult to form. It will result in a reduction in the number of island components or the formation of uneven sea components-10- (»20 '> / 26 / Ι1: 50ΛΜ c: I I.uh, 1 * 1 ·· I'm m ( 44, ilt) c This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm), 512189 " .. 91.09. 26 Amends this B7 V. Description of the invention (7), so the fluffing property in the fluffing process will be It becomes difficult to show the appearance and feel of the final product. Moreover, the difference in melting viscosity [^ MV] between the sea component and the island component is lower than 10,000, which is less than 1,000 poises [PQise]. The difference in melting and melting viscosity between the sea component and the island component [ΔΜν] is greater than 1,000 poise. The island component will stick to each other during the weaving process, and the island component produces unseparated fibers. It remains after the dissolution treatment. Cannot be separated. For the above reasons, 'the fiber has a raised state that may cause the yarn knitted fabric to become uneven, the appearance becomes dirty, the writing effect becomes worse, and the touch feels thicker. The melting viscosity of the island-based polymer is Can be adjusted by the original viscosity, and the melting viscosity of the sea polymer I: It can be adjusted by appropriately adjusting the type of copolymer, the content of the copolymer, and the copolymerization reaction conditions. For example, when adjusting the melt viscosity of the marine component polymer, the DIMS of 3 to 15 mole { Copolymerize ethylene phthalate, and add 4 to 20% by weight of polyethylene-glycol with an average molecular weight greater than 8,000 °. Next, the sea-island composite fiber of the present invention is prepared by using a first guide wire. The spinning yarn is wound between the wheel and the second guide wheel, and is prepared by winding the yarn with a winding machine. That is, the sea-island composite fiber of the present invention is prepared by a direct spinning method, that is, spinning and spinning are completed by the same process. Compared with the preparation of a large number of sea-island composite fibers by the textile spinning false twist method, the present invention can prepare yarns with flat properties, so it is more suitable for packaged yarn knitting.

Invention Description (δ) At this time, the speed [Vi] of the first godet wheel is 1,000 to 5,000m / min, preferably 1,000 to 3,000m / min, and the second godet wheel The speed [V2] is set to 1,500 to 6,000 m / min. If the speed of the first and second godet wheels is lower than the above range, the yarn will not be able to be oriented and crystallized, so the cutting after the raising process will become uneven, and the degree of weight loss cannot be controlled in the weight loss process. . Furthermore, if the speeds of the first and second godet wheels exceed this range, the birefringence and crystallinity of the island components in the yarn will be reduced, so the physical properties that the yarn should have cannot be achieved, and therefore the yarn will be lowered. This improves the usability of this yarn. In addition to controlling the speeds of the first and second godet wheels, the physical properties of the yarn in the textile system can be adjusted by appropriately adjusting the spinning temperature, spinning ratio, and cooling of the sea-island type polymer 4 and the like. Conditions and melt viscosity. First, a preparation condition is used to set the crystallinity of the yarn on the first godet, that is, the crystallinity of the yarn passing through the first godet is 8.5 to 25%. If the crystallinity is higher than the above range, it will be difficult to complete spinning in a button region, and the process will not be continued. If the crystallinity is below the above range, additional spinning is required in order to obtain the desired physical properties of the yarn. It causes additional spinning tension, thereby increasing the variability of the physical properties and causing problems in the manufacturing process. In addition, another preparation condition is used to set the birefringence [Δη] of the island component of the composite fiber on the second godet to 0.10 to 0.20.

In order to obtain a more suitable The sea-island type composite fiber is preferably controlled at each stage of the following weaving process to control the properties of the yarn, but it is not intended to limit the present invention. In addition, the yarn on the first to godet wheel preferably has A coefficient of 5 to 35 g / d. If the coefficient of the yarn on the first godet wheel deviates from the above range, the stress applied to the yarn will be excessive, and the fiber bundle will burst or the yarn will break , Thus reducing the usability of textiles. The preparation conditions are used to set the birefringence of the island component of the yarn on the first godet wheel [Λη], that is, the birefringence of the island component of the yarn through the first godet wheel [△] η] is between 0.005 and 0.090. If the birefringence is larger than the above range, a mechanical stress will become too large, thus causing a cracking phenomenon. If it is smaller than the above range, the coefficient and strength of the yarn And the ductility will be too low to allow spinning. In addition, 'another preparation condition is used to set the yarn on the first godet to have a coefficient of 60 to 90 g / d. If the coefficient is lower than the above range, the The density of the yarn will become lower, and the ductility will become too high, the mechanical strength will become higher, and the pile of wool yarns will become thicker, thus weakening the effect of the sea-island type fine yarn. A preparation condition is used to set the crystallinity of the yarn on the second godet wheel to 25 to 45%. If the crystallinity is less than the above range, the paper size is applicable to China National Standard (CNS) A4 ( 210X 297 mm) (Please read the notes on the back first (Write this page), τ printed by 512189 91.09.26 amended by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs.

If the crystallinity is higher than the above range, the fiber becomes hard due to excessive orientation and crystallization, and makes It is not suitable for the yarn used for yarn weaving. The physical property change of the yarn on the first godet can be measured by the following method. The sampling method of the yarn on the first godet is as follows As described. First, the yarn at the front end of the first godet is cut by a cutting tool, and the yarn at the rear end of the first godet is cut by a cutting tool almost simultaneously, and then cut Immediately after the yarn was dropped, the yarn wound on the surface of the first godet wheel was removed as a sample. More specifically, the yarn is fixed on the surface of the fibrous layer wound on the first godet wheel, and when it is cut, sampling is performed immediately to avoid the occurrence of the first, fT ,,: V ,, and > · Changes in physical properties due to the temperature of a godet. The change in the physical properties of the yarn of the second godet wheel can be measured by the following method. The method of sampling the yarn on the second godet is as follows.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs as shown in Figure No. 4 in Figure 1, the sea-island composite fiber produced by the present invention for yarn weaving has the following characteristics: First, the initial shrinkage of the composite fiber The starting temperature is between 55 and 90 ° C. The yarn is drawn between the first and second godets, and its transition from a low-orientation, low-crystallinity state to a high-orientation, high-crystallinity state will cause the initial shrinkage onset temperature to be reduced. r I nul »ΙΊ I'm ΓΙ t M4 dot-14-〇2 / (W / 26 / Μ: 50 ΛΜ) This paper size applies to China National Standard (CNS) A4 specification (210X297 mm), 512189 A7 B7 91. 09. 26 Amend this V. Description of the invention (11) Therefore, if the initial shrinkage onset temperature is lower than 55 ° C, the crystal orientation will be too high. If the initial shrinkage onset temperature is higher than 90 ° C, The crystal orientation will be insufficient, making the composite fiber unsuitable for use as a yarn for yarn weaving. In addition, the maximum thermal stress temperature of the composite fiber is between 130 and 160 ° 0. At this maximum thermal stress At the temperature, the thermal shrinkage of the fiber is the best. Moreover, most of the yarn textile fiber post-processing process can be completed within the above range. Therefore, if the maximum thermal stress temperature is lower than the above range, then The initial process of the post-treatment will cause excessive shrinkage, and it will be difficult to control the post-treatment process. If the maximum thermal stress temperature is higher than the above range, the post-treatment will not have sufficient shrinkage, and therefore the volume of the yarn knitted fabric And the density will decrease, its knot As a result, the appearance and feel of the final product become worse. In addition, the maximum thermal stress per denier of the composite fiber is between 0.150 and 0.250 g. The thermal stress is related to the use of a certain degree of heat treatment in the process to use the yarn .If the maximum thermal stress per denier is lower than the upper range, it will cause insufficient crystal orientation and increase the degree of extension. If it is higher than the above range, it will cause excessive crystal orientation, and the yarn The line becomes thicker. That is, if the maximum thermal stress per denier deviates from the above range, the later manufacturability will deteriorate and the appearance and feel of the fiber itself will decrease. As described above, the sea-island type of the present invention The heat shrinkage properties of the composite fibers are relatively consistent with each other. As a result, the formability, fluffing properties, and feel of the cross section of the yarn are excellent, and the paper size is applicable to China in the process of dissolving the seawater ingredients and the fluffing process.
