[Prior Art] Heretofore, the following methods have been known as a method for composite discontinuous fiber bundles and multifilaments: (1) A multifilament yarn which is substantially bundled with a stretched discontinuous fiber bundle in a bundled state, And twisting and winding them (1 -1 ) or temporarily twisting and bundling them to form a yarn (1-2) wound around the pile; (2) the stretched fiber bundle is an open fiber multifilament Wrap, then twist and wrap them (2 -1 ), or temporarily twist and bundle them to form a looped yarn (2 - 2). However, the method (1-1) has a drawback in that the number of turns of the conventional yarn composed of the cut fibers is applied to improve the entanglement of the stretched discontinuous fiber bundle and the multifilament. Method (1-2) has the disadvantage that since the discontinuous fibers and the multifilaments are not sufficiently entangled by temporary twisting and bunching, they should be glued, fused or moderately twisted. The method (2-1) has the disadvantage that the twisted and wound yarn has a tacky -5 - 1374203 ι · ' » * ' i . ' that is called a lightly filled or sparkling appearance, although it has uniformity. In the method (2-2), the multifilament yarn is excessively opened or opened, so that the cut fiber does not sufficiently function to surround the pile' and thus the longitudinal bundled state is uneven in many cases. A method of kneading a fiber bundle and a bulky strand is proposed (for example, JP-A-49-1 0 1 639). However, this method has a drawback in that the yarn has a poor appearance because the fiber bundle should be manufactured in an excessive feed state and using a high-speed rotary jet, which is easily formed into a fiber knot and a spot. Further, 'a composite yarn comprising a monofilament component and a discontinuous fiber component is proposed' in which a monofilament component in an actual twist state exists in a core portion; and a discontinuous fiber component is present in a cortical portion (for example, JP-A- 59-', 3 0925 and Jp-A-61-23 903 6). However, this composite yarn has insufficient appearance of pepper-and-marble when it is dyed in different colors, has a large number of stained small spots in the case of deep dyeing, and causes a lot of trouble when being woven. • Among synthetic fibers, acrylate fibers are attractive because they have excellent functions (temperature-control, moisture-control, blending). With these characteristics, the blend of acrylate fibers and other materials is used in sports and interior applications. However, the acrylate fiber has only a strength of 0.55 to 1.82 g/d and a non-strength of 0.30 to 1.5 d/g. Therefore, when the acrylate fibers are blended with other materials, they are damaged and the discontinuous fibers break and the fibers fall. These disadvantages of the acrylate fibers become remarkable as the percentage of acrylate fibers in the mixed yarn increases. -6 -

1374203 When the percentage of acrylate fibers in the mixed yarn is reduced, the above disadvantages can be overcome, but the characteristics as functional fibers are greatly deteriorated, which is a fatal problem. Therefore, conventional mixed yarns comprising acrylate fibers have problems from the viewpoint of yarn properties and yarn quality. In particular, the strength of the yarn is greatly reduced because of the nature of the acrylate fiber and the damage of the acrylate fiber during processing. Therefore, the percentage of acrylate fibers in the mixed yarn is greatly limited. In addition to this, the number of yarn counts is limited to a large number of yarn counts. Regarding the yarn quality, the breakage of the discontinuous fibers occurs in the processing of the acrylate fibers, increasing the number of fiber knots produced at the time of spinning and further increasing the number of regions in which the fiber knots are concentrated in the longitudinal direction of the yarn. Therefore, the yarn quality is remarkably reduced. When the fabric containing the yarns is dyed, the area where the fiber knots are concentrated sees white, so the quality of the fabric is greatly reduced. Therefore, the mixed yarn containing the acrylate fibers is used on the back side of the fabric or in applications where high quality fabric is not required. When they are used in consideration of the properties of the acrylate fibers, it is often attempted to honinate the acrylate fibers into a short length and to coat the honed fibers with a paint or the like. This method is excellent from the viewpoint of the application of functional properties because the acrylate fiber is coated with a coating or the like and the texture of the fabric is hardened and the thickness of the fabric is increased. Therefore, the inherent texture of the fabric is impaired. Therefore, this method can be used in limited applications. In these years, it is highly desirable to utilize the high quality of the acrylate fibers for high quality sports - interior fabrics. However, as explained above, it is difficult to impart high functional properties to the acrylate fibers of the fabric by increasing the percentage of acrylate fibers in the mixed yarn. Therefore, it has not been provided - 1374203

A composite yarn comprising acrylate fibers. In order to prepare a composite yarn, a method of opening an electric fiber is known (for example, JP-A-54-17063 and U.S. Patent No. 3,657,871). Also known is a double-layered yarn and a composite yarn comprising a fiber bundle and a single monofilament (for example, JP-A-6-228838 and JP-A-2000-17532). However, these patents disclose that composite yarns comprising acrylate fibers are not disclosed. A composite yarn of continuous and discontinuous fibers is supplied in the form of a mixture of various fibers and is produced by various compounding methods. However, composite yarns of continuous fibers and discontinuous fibers are not known which contain a dyed fiber to improve texture or color tone. When these dyed fibers are used, there are problems that arise: the fibers dyed by the dope have an unevenness because of the uneven mixing or the processing in the production of the dyed fibers. The process, for example, the weaving of the weir or the tailoring needle is worn by the fine particles of the original colorant. As the yarn dyed by the spinning solution, such synthetic fibers such as polyester, polyamide, etc., which contain mixed colored particles such as pigments, are known. However, ® does not know the fiber opening of the yarns. In particular, black polyester fibers (hereinafter referred to as "spun black dyed fibers") produced by sputum dyeing are carbonized by a polymerization method or any step after polymerization to fiber formation. Black is added to the polyester to produce (for example, JP-A-8-13248). However, when the composite yarn is produced by fiberizing the black dyed fibers, it is difficult to uniformly open the fibers ( For example, jp_B_4-78749 and JP-B-54-1 7063), the resulting composite yarn has significant color spots and cannot be used to make woven fabrics for dresses (or gowns). When the fibers are unevenly opened At the time 'the color spots are more pronounced in the fabric containing the fibers. -8 -

1374203 When the composite yarn is prepared as described above, the device for electrically opening or expanding the fiber is a known device for opening the multifilament. For example, J ρ · υ Μ (using the model)-5 0 -9366 Α reveals a device 'Using the device, the multifilament is passed through a hollow cylindrical electrode for supplying a voltage and then through a grounding ring to electrically charge the wire and open Fiber or open the fiber, and JP-UM-50-35149A discloses a device by which a pressurized liquid is sprayed onto a multifilament, which then passes through a hollow cylindrical electrode for supplying a voltage and then through a ground. The ring electrically charges the filament and opens the fiber. The degree of fiber opening of the multifilament using such a fiber-fiber opening device depends on the tension applied to the yarn, environmental conditions (e.g., temperature, moisture, etc.), the type of multifilament, and the like. For example, as the speed at which the multifilament moves increases, the amount of charge on the multifilament decreases and the tension on the filament increases. Therefore, the degree of fiber opening is reduced. Therefore, the strength of the supply voltage, the conveying speed of the filaments, and the tension on the filaments should be determined according to the worker's experience or preliminary experiment to achieve a stable degree of fiber opening regardless of changes in the preparation conditions. Therefore, an electric fiber fiber opening device which can achieve a stable fiber opening degree and a variation in preparation conditions has been sought to improve the manufacturing efficiency. This type of fiber opening device allows the multifilament to pass through a hollow cylindrical electrode for supplying a voltage to charge and unwind the yarn. Therefore, when the fibers of the multifilament are completely opened, the fibers are continuously contacted with the fiber outlet of the electrode, so the fiber outlet tends to wear. That is, when the multifilament is completely opened, the worn electrode should be replaced from time to time, which causes another problem of reduced manufacturing efficiency due to the stoppage of manufacturing to replace the electrode. 1374203

Accordingly, an electric fiber fiber opening device capable of preventing abrasion of an electrode for supplying a voltage to a multifilament while maintaining a fiber opening degree of a sufficient multifilament has been sought. A first object of the present invention is to provide a composite yarn of continuous and discontinuous fibers which utilizes the good hand of discontinuous fibers and the uniformity and high strength of continuous fibers to improve weaving properties, resulting in lighter and less translucent The woven fabric reduces the staining spots that may cause problems when the yarn is deeply dyed black for use in a black dress, and has good deep dyeing properties, and a method of preparing the yarn. The second object of the present invention is to provide a composite yarn of continuous and discontinuous fibers which can utilize the good hand of discontinuous fibers and the uniformity and high strength of continuous fibers, reduce the number of raised fibers, and improve the weaving properties. When the monofilament and the discontinuous fiber are dyed in different colors, the salt and pepper pattern is improved, and the staining spots which may cause problems when the yarn is deeply dyed for use in a black dress are reduced, and a method of preparing the yarn is prepared. A third object of the present invention is to provide a yarn which exhibits high functional properties of acrylate fibers, in particular, which prevents deterioration of inherent properties, • strength non-strength, and suppression when acrylate fibers are mixed with other materials.

DETAILED DESCRIPTION OF THE INVENTION First, a continuous and discontinuous fiber composite yarn according to the first aspect of the present invention and a method of manufacturing the same are explained by referring to the drawings. The drawings are intended to illustrate the invention and are not intended to limit the scope of the invention. The continuous and discontinuous fiber composite yarn of the present invention comprises a multifilament of synthetic fibers and discontinuous fibers which are opened and mixed by the fibers. Figure 1 A shows the composite -14-

1374203 Cross-sectional structure of the yarn 'The core portion thereof comprises a homogeneous mixture of the multifilaments of the 12 and the discontinuous fibers 13, comprising discontinuous fibers surrounding the central portion. The discontinuous fiber composite yarn having this structure can provide a fabric with less translucency. When the yarn is knitted or woven, the fabric has less staining spots when the fabric is used to sew a black dress. Preferred examples of the synthetic fiber constituting the composite yarn include terephthalate propylene glycol fibers, polyamide fibers, polyacrylonitrile fibers, polybutylene terephthalate fibers, and among them, polyester fibers. For better. Preferred examples of the discontinuous fibers constituting the composite yarn include silk, hemp, linen, ramie, synthetic fiber cut fibers, acetate cut fibers, and mixtures thereof. Among them, the multifilament of synthetic fiber and discontinuous fiber is opened and the entanglement of the discontinuous fiber and the subsequent processing of the modified yarn indicate that the multifilament and the discontinuous fiber exist in a mixed state. . The discontinuous fibers are uniformly mixed uniformly in the central portion of the yarn so that the degree of entanglement of the fibers is high at the center portion. Therefore, weaving properties. At the same time, the discontinuous fiber layer surrounds the central portion so that the yarn has a convex structure, so that the yarn is manufactured from this type of yarn, and has less translucency and a wooly texture. Preferably, the multifilament of the synthetic fiber has a multifilament of 11 to 11 Å of fiber and the peripheral portion is coated with a light one, and contains the deep dyeing property and a polyester fiber, a polyolefin fiber, and a polymixture. In his wool, cotton, staple fiber, wool is better blended to increase complex properties. In the mixed expression, the multifilament and the multifilament and the discontinuous yarn have a good uniform layer of the fabric. The fabric has a lightness and the fineness of the taxi -15- 1374203

Second

. When the composite yarn is not in a certain range, it is not accepted in the market. When the fineness of the multifilament is less than 11 cents, the composite effect may not be achieved. When the fineness of the multifilament exceeds 110 cents, the fabric made from the yarn may lose the feel of the wool. The above range of fineness is desirable for the manufacture of a marketable fabric having a wooly feel. In order to impart a touch to the fabric of the fabric, it is preferred that each of the monofilaments has a fineness of 0.1 to 6.6 ^ cents, more preferably 0 to 2 to 3.3 cents. When the fineness of each monofilament is less than 0.1 cents, the fabric may lose stardiness. When the fineness of each monofilament exceeds 6.6, the texture of the fabric may be far from the wooly texture. When staple fibers other than natural fibers are used as the discontinuous fibers, they may be cuts of equal length or unequal lengths. The average length of the artificial short ' fibers is preferably from 50 to 150 mm for fabrics with wool warmth, or from 25 to 50 for fabrics with cotton warmth, in the above composite yarns, the amount of discontinuous fibers. Preferably, it is from 50 to 95% by weight based on the total weight of the yarn. When the amount of discontinuous fibers is less than 50% by weight, it may be difficult to surround the uniform mixture layer of the discontinuous fibers and the multifilaments with the discontinuous fiber layer. When the amount of the discontinuous fibers exceeds 95% by weight, the entanglement of the multifilaments and the discontinuous fibers may be deteriorated. The composite yarn according to the first aspect of the invention preferably has a raised number of from 300 to 900 fluff/l〇m of the pile of at least 1 mm length. More preferably, it has a raised count of 80 to 200 piles/10 m of fluff of at least 3 mm length. When the number of raised hair is within the above range, the fabric made from the composite yarn is -16-1374203

Lightweight, less semi-transparent ~ lightness and wooly texture. Here, the number of raisings was measured using an F-rate tester manufactured by Shikibo Co., Ltd. When viewing the cross section of the composite yarn, a central portion consisting of a homogeneous mixture of synthetic fibers and multifilament fibers is generally seen, while the peripheral portion contains discontinuous fibers and surrounds the central portion. This structure is one of the characteristics of the composite yarn of the first aspect of the invention. The composite yarn of the first aspect has a good entanglement of the monofilament and the discontinuous fibers and a wool touch and provides a woven fabric having a light weight and less translucency. In addition, when the composite yarn is used in the manufacture of a black dress fabric, the fabric has deep dyeing properties and less staining. Therefore, the fabric is suitable for sewing men's wear, dresses, high-quality ladies or blouses. The lightweight fabric according to the present invention can be used as the warp and/or weft yarns and the average density coefficient of the warp and weft yarns by using the above-mentioned continuous and discontinuous fiber yarns in the case of plain weaves from 35 to 47, preferably from 3 The range of 8 to 45, or in the case of a twill fabric, is from 45 to 50, preferably from 48 to 57. Here, the plain weave fabric represents a plain weave fabric of any of the three original tissues, and includes a modified plain weave such as a flat weave, a matte finish, and the like. The twill fabric represents a twill fabric of any one of the three original tissues' and includes a modified twill such as a sharp twill 'diagonal twill. In the case of plain weaves, when the average density factor is less than 3 5, the fabric has a large translucency and may lose practical properties. When the average density coefficient exceeds 4 7 , the fabric may not have sufficient gas permeability. In the case of twill fabrics' when the average density factor is less than 4 5 -17 - 1374203 螂7 __ * Jy I /* -*· » 曰

Supplemental I fabrics may lose practical properties. When the average density factor exceeds 60, the woven fabric may not have sufficient gas permeability. The average density coefficient is calculated as follows: The density coefficient T of the warp yarn is calculated by the following formula: D = (number of warp yarns / l 〇 Cm mesh) / (count) m The density coefficient of the weft yarn T is calculated by the following formula:

T = (number of weft yarns / l 〇 cm) / (count) 1/2 The average density coefficient is calculated by the following formula: Average density coefficient = (T + W ) /2 The air permeability of the lightweight fabric of the present invention is preferably At least 50 cc/cm2/sec, more preferably at least 90 cc/cm2/sec. When the gas permeability is less than 50 cc/cm2/sec, the fabric may lose ventilation-radiation properties, so it may not provide a cool or refreshing sensation. Breathability can be measured with a Furajeal type tester. The above composite yarn having the special cross-sectional structure of the present invention can be produced as follows

The multifilament of the synthetic fiber is electrically opened or expanded into individual multifilaments. Then, the open multifilament is entangled with the discontinuous fibers stretched only before the front roll, at which point the center of the expanded multifilament and the center of the discontinuous fiber are aligned. In addition, the fiber opening width of the multifilament is controlled by the supply tension or the fiber opening voltage or by using a special yarn guide to concentrate the mixed layer of the multifilament fiber and a part of the discontinuous fiber on the composite yarn. Center, while the remaining discontinuous fibers surround the mixed layer to narrow. In the method of manufacturing a composite yarn according to the present invention, when they are only in the front -18 -

1374203 When the fiber opening width of the multifilament exceeds the maximum width of the discontinuous fiber bristles, it is not possible to obtain a yarn structure which causes the discontinuous fibers to surround the uniform mixture layer of the monofilament and the discontinuous fibers. Therefore, since the fuzzing effect of the monofilament is increased, it is impossible to manufacture a lightweight fabric having less translucency. The fiber opening width of the multifilament of the synthetic fiber is usually equal to or less than the maximum width of the discontinuous fiber bristles, preferably from 10 to 60% of the maximum width of the discontinuous fiber bristles. Thereby, a uniform mixture of monofilaments and discontinuous fibers constitutes a central portion of the composite fibers and the remaining discontinuous fibers surround the central portion. Thus, the specific structure and effect of the yarn can be achieved, for example, the improved woven quality' has a lighter and less translucent fabric, deep dyeing properties and reduced staining. When the fiber opening width of the multifilament of the synthetic fiber is less than 10% of the maximum width of the discontinuous fiber hair, the fiber opening effect is deteriorated, so the weaving property is reduced to the extent of the core yarn, and the above invention may not be achieved. Effect. The position at which the multifilaments and discontinuous fibers are supplied can be adjusted by controlling the position of the fiber opening electrode' or by using a specific yarn guide of the open fiber monofilament. The fiber opening width of the multifilament can be adjusted by controlling the voltage, the supply tension, the specific yarn guide for the monofilament, and the like. The continuous and discontinuous fiber composite yarns of the present invention can be made using the apparatus shown schematically in Figure 2. Referring to Figure 2, the apparatus comprises a rear roll 1, a carriage 2 and a front roll 3 which are assembled in this order in the order of -19 - 1374203 - year a a . Below the front roller 3, a winding machine 10 for the volute guide ring and the traveler 5 is provided. Above the front roller 3, the electrode 6 and the yarn guide ring 7 are provided in this order from the upper end. In order to produce a continuous and discontinuous fiber composite yarn, the multifilament is unwound and passed through the yarn guide 9 to the electrode 6. The electrode 6 supplies static charge to the multifilament A, which is passed through the electrode 6, so that it is not monofilament. The charged multifilament is then fed through the yarn guide ring 7 and then supplied to the front section of the fiber opening width and supply position. Separately, the coarse discontinuous fibers B are supplied to be stretched between the rear roll 12 and the front roll 3. Thereafter, the discontinuous fibers B are supplied to the front roller 3 in a bundle form of B. Then, the multifilament A' is opened or unwound, and is not connected; the bundle of hair forms is mixed or entangled at the rolling point of the front roll 3. At the center of this filament A is substantially the center line of the discontinuous fiber bristles and the fiber opening width of the multifilament A is preferably adjusted to 10 to 60% of the maximum width. A mixture of multifilament A and discontinuous fiber bristles is twisted to form a specific yarn structure such that the cross section of the yarn has a central portion of the uniform mixed layer of continuous fibers and a peripheral layer surrounding the central fibers. Finally, the twisted yarn passes through the worm thread guide 4 and then the loop and the winding device 10 of the traveler 10. Next, the continuous yarn joining according to the third aspect of the present invention, and a method of manufacturing the composite yarn will be explained. 4 and a front roller 3 which is provided with a fiber opening A from the hollow electrode of the tweezers 8 and the yarn is expanded into a roller 3 and then adjusted in the stage of the discontinuous fiber bundle B of the carrier, and the core is re-centered into the continuous fiber hair.

The continuous and discontinuous fiber composite yarn comprises a multifilament of synthetic fibers and discontinuous fibers, which are opened and mixed by fibers, and the composite yarn has a structure in which a multifilament layer and a discontinuous fiber layer are spirally wound, and in each spiral In the layer, the multifilament layer is present on the outside, and when the discontinuous fiber layer is present on the inside, as shown in Fig. 1B. The composite yarn having the structure can provide a woven or knitted fabric having a wooly feel, and a modified salt and pepper pattern when the monofilament and the discontinuous fiber are dyed in different colors, and the fabric containing the yarn has deep dyeing properties and is used as a fabric. To sew black dresses, there are fewer stain spots and also have little fluff and good breathability. Therefore, the fabric made from this composite fabric is suitable for sewing men's wear, dresses, bureau-quality ladies' clothes or short tops. The multifilament synthetic fibers and discontinuous fibers may be the same as those used in the composite yarns of the first aspect of the invention. With regard to the fineness of the multifilament and the fineness of each monofilament, the description relating to the composite yarn according to the first aspect of the present invention is applied to the composite yarn according to the third aspect of the present invention. In the case of the composite yarn according to the third aspect of the present invention, the amount of the discontinuous fibers is preferably from 35 to 95% by weight based on the total weight of the yarn. When the amount of the discontinuous fibers is less than 35 % by weight, the discontinuous fibers and the multifilament may not be sufficiently entangled or mixed. When the amount of discontinuous fibers exceeds 95% by weight, it may be difficult to produce a composite yarn having few spots. The composite yarn according to the third aspect of the invention preferably has a raised number of from 200 to 900 pieces of hair/i〇m of a pile length of at least 丨 mm. More preferably, in addition to the above-mentioned raising number, which has a hair-cut length of at least 5 mm, 30 - 21 - 1374203

The number of fluffs of 10m or less. When the number of raised yarns is in the above range, the fabric produced from the composite yarn has improved post-processing properties such as weaving properties to maintain the wooly texture, and further improves the quality by suppressing the formation of the fiber knot in the weaving method. Again, the number of rises was measured using an F-rate tester manufactured by Shikibo. The characteristic multifilament of the composite yarn according to the third aspect of the invention and the discontinuous fiber are spirally wound. The direction of the spiral can be clockwise or counterclockwise. The direction of the helix can be controlled by the entanglement of the continuous fiber bundle and the discontinuous fiber bundle during the spinning process. The composite yarn according to the third aspect of the present invention can be used to manufacture the same fabric as the fabric manufactured from the composite yarn according to the first aspect of the present invention, and the composite yarn manufactured from the first aspect of the present invention. The explanation of the fabric is applied to a fabric manufactured from the composite yarn according to the third aspect of the present invention. The composite yarn according to the third aspect of the present invention can be entangled by a multifilament of an electrically opened synthetic fiber and a discontinuous fiber stretched only before the front roll, wherein the maximum opening width of the hair of the discontinuous fiber The maximum opening width h of the weft and the continuous fiber multifilament at the entangled point has the multifilament and the discontinuous fiber entanglement such that the distance from the edge point of the width Η to the edge point of the width h is changed by 10 of the maximum width Η 90% relationship. In the above manufacturing method, it is important to change the supply shaft of the multifilament of the synthetic fiber and the supply shaft of the discontinuous fiber, when the fiber-wound multifilament of the synthetic fiber is entangled with the discontinuous fiber stretched only before the front roll. The maximum opening width h of the multifilament of the synthetic fiber is preferably equal to or greater than the maximum opening width Η of the discontinuous fiber bristles. When the maximum opening width h is less than the maximum -22- I3?4203 X r

When the width J of the large opening is large, the effect of the opening of the layer having the monofilament is reduced and the quality of the weaving and the quality of the fabric in turn are deteriorated. In the composite yarn according to the third aspect of the invention, the multifilaments and the discontinuous fibers are overlapped with each other such that the width corresponding to the width of 90 to 1 〇 %, preferably 80 to 20 %, overlaps the width h. Thereby, the composite yarn has a special structure in which the multifilament layer and the discontinuous fiber layer are spirally wound and it is expected that the composite yarn has good properties such as little fluff, improved weaving properties, and different monofilaments and discontinuous fibers. Improve the appearance of salt and pepper when coloring, and reduce the staining spots when the yarn is deeply dyed. If the opening width h of the multifilament of the synthetic fiber does not overlap with the opening width of the discontinuous fiber bristles, or they are separated from each other, the structure of the composite yarn is corrected so that the spiral structure cannot be formed and thus the above effect cannot be attained. The supply position of the multifilament of the synthetic fiber and the discontinuous fiber wool may have an influence on the structure of the yarn to be produced. In the case of spinning a yarn having a twist-twist, the multifilament of the synthetic fiber is displaced to the right with respect to the discontinuous fiber hair. In the case of spinning a yarn having S-twist, the multifilament of the synthetic fiber is displaced to the left with respect to the discontinuous fiber. Thereby, the desired yarn structure is stably obtained. In these cases, the winding direction is clockwise in the case of Ζ-捻 rotation or counterclockwise in the case of S-捻 rotation. The position at which the multifilament and discontinuous fibers are supplied can be adjusted by controlling the position of the fiber opening electrode or by using a specific yarn guide for the open fiber monofilament. The fiber opening width of the multifilament can be controlled by voltage, supply tension, and used for monofilament -23- 1374203

I ^ A B L, ._M^i specific yarn guides and so on. The composite yarn according to the third aspect of the present invention can be manufactured using the apparatus shown in Fig. 2, which has been explained, while controlling the textile conditions. In order to produce a continuous and discontinuous fiber composite yarn, the multifilament A is unwound from the tweezers 8 and passed through the yarn guide 9 to the electrode 6. . The electrode 6 is a hollow electrode and supplies static electricity to the multifilament A, which is passed through the electrode 6, so that the yarn is expanded into individual filaments. The charged multifilament is passed through the yarn guide ring 7 and then supplied to the front roller 3 while adjusting the fiber opening width and the supply position. Separately, the coarse discontinuous fibers B are supplied to the rear roll 1 and then stretched between the carrier 2 and the front roll 3. Thereafter, the discontinuous fibers B are supplied to the front roll 3 in the form of a bundle of discontinuous fibers - B. Then, the multifilament A, which has been opened or opened, and the bundle of the discontinuous fibers B are mixed or entangled at the rolling point of the front roll 3. In this stage, the maximum fiber opening width of the discontinuous fiber bristles is laminated at a distance of 10 to 90% of the maximum fiber opening width of the multifilament. ^ A mixture of multifilament A and discontinuous fiber bristles, which are passed through a front roll 3, to be twisted to form a specific yarn structure such that the cross-section of the yarn has a central portion of the uniform mixed layer of monofilaments and discontinuous fibers and encloses The peripheral layer of the discontinuous fibers in the central portion. Finally, the twisted yarn passes through the volute guide 4 and is then wound on a winding machine 1 having a ring and a bead ring 5. Now, a composite yarn according to the fifth aspect of the present invention will be explained. The composite yarn according to this view is a continuous and discontinuous fiber yarn comprising acrylate fibers. The acrylate fiber used in this composite fiber is -24-

1374203 A fiber of crosslinked copolymer of acrylic acid or its salt with a light metal and acrylamide, and having temperature-control, moisture-control, and harmonic properties. However, as already explained, the acrylate fibers have very weak strength and non-strength, which is about one-half to one-third of other synthetic fibers used as clothing materials, such as polyester fibers. Therefore, it is necessary to mix acrylate fibers with natural fibers and/or synthetic fibers. In order to produce a yarn of high quality, it is necessary to form a composite yarn from a monofilament of synthetic fibers. When a mixture of acrylate fibers and natural fibers and/or synthetic fibers is combined with monofilaments of synthetic fibers, the yarns can have high strength, and thus can be spun with relatively small counts of yarns and acrylate fibers in the composite yarn. The percentage can be increased. In order to obtain a high quality yarn, it is preferred to have a composite configuration such that the fiber bundle of the mixture of the acrylate fiber and the natural fiber and/or the synthetic fiber is entangled by the monofilament of the synthetic fiber. The monofilament of the synthetic fiber can be any monofilament used for clothing. Polyester and polyamide resins are preferred in view of strength. Yarns having a filament count of at least 5 are preferred in view of yarn quality. The percentage of the monofilament in the composite yarn is preferably from 10 to 35 %. When this percentage is less than 1%, the properties and quality of the yarn may not be improved. When the percentage exceeds 35%, the quality of the fiber bundle containing the acrylate fiber is reduced. As a result, the mixing ratio of the acrylate fibers and the spinning count are greatly restricted. The mixing percentage of the acrylate fibers is preferably from 5 to 45%, more preferably from 10 to 40%, from the viewpoint of functional properties and yarn quality. When acrylate -25-1374203

When the mixing percentage of the supplementary I fibers is less than 1%, the three properties, that is, temperature-control, moisture-control, and harmonic properties may not be sufficiently improved. When the mixing percentage of the acrylate fibers exceeds 40%, the yarn quality is remarkably reduced, and the high percentage of the acrylate fibers is undesired from the viewpoint of cost. The composite yarn according to the fifth aspect of the present invention preferably has 200 piles. /1000m or less, more preferably 100 raised/1000m less concentrated hair. In order to produce a high quality fabric, the composite yarn preferably has 100 fluff/1000 m or less, in particular, 70 fluff/1000 m or less concentrated. Because if the number of fluffs is large, the acrylate fibers are not 'dyable' and the portions of the fabric that are concentrated in the fluff are white after dyeing the fabric. Therefore, the quality of the fabric is significantly reduced. Various test results show that the concentrated fluff is composed of acrylate fibers. The mechanism of generation of concentrated fluff of acrylate fibers can be assumed as follows: ^ In the processing method, 'a lot of discontinuous fiber breaks due to abrasion by metal and other fibers, and poor fiber stretching causes fiber defects to increase and thus concentrate Fluff. Since the concentrated fluff contains the nine-shaped fluff formed in the same area, the number of concentrated fluff is easily calculated. Specifically, the number of concentrated fluffs was calculated as follows: The yarn was wound around the yarn board at a pitch of 20 yarns/twist. Four yarns of wound yarn are produced. Then the number of concentrated fluff found on the yarn is calculated and converted into the number of yarns per 1 000 m. The production of concentrated fluff is only -26- 1374203 when the yarn contains acrylate fibers.

This phenomenon becomes more pronounced, and yarns that do not contain acrylate fibers sometimes produce concentrated fluff. These high quality yarns having 100 fluff/l〇〇〇m or less concentrated fluff can be produced by composite acrylate fibers and monofilaments. The composite configuration of the yarn is not limited and the following configurations may be particularly advantageous. The monofilaments, which are supplied from a monofilament supply assembly and fiber-opened with an electrical fiber opening device, and a fiber bundle of acrylate fibers and natural and/or synthetic fibers, which are supplied from a coarse fiber supply assembly, entangled, and then They were smashed to obtain high quality yarns (with a concentration of 100 fluff/100 m or less of concentrated fluff). The reason why a high quality yarn is obtained may be that the concentrated fluff of the acrylate fiber is wound or opened to a monofilament that is separated into individual monofilaments. In addition to the above method, the following method for producing a composite yarn by twisting a discontinuous fiber bundle (B) of acrylate fibers and natural and/or synthetic fibers and a continuous fiber bundle (A) of synthetic fiber monofilaments can be used. That is, the 'multifilament yarn, which is substantially in a bundled state, is entangled with the bundle of fibers to be stretched' and then twisted and wound, or temporarily twisted to form a yarn having a wound pile. Alternatively, the drawn fiber bundles are wound with the fiber-wound multifilaments and then twisted and wound, or temporarily twisted to form a yarn having a wound pile. The composite yarn according to this aspect can be produced by any of the above methods. The high-quality composite yarn according to the fifth aspect of the present invention can also be supplied from the monofilament supply unit by the entanglement through the supply yarn guide. The supply of acrylate fibers and natural and / or synthetic fibers -27 - 1374203 J〇o praise complements the bundle to form the first fiber bundle, while tensioning mechanisms such as tension should be tensioned to the monofilament, then倂 The first fiber bundle and the second fiber bundle comprising natural fiber or synthetic fiber but no acrylate fiber and the fiber bundle and the second fiber bundle are separated by a distance of 3 to 8 mm, and the upper band is turned. In the above method, the first and second fiber bundles are twisted to wind the fiber bundles of the type. Therefore, the disturbance of the fiber orientation and the generation of the hair raising are suppressed. In addition to this, the first fiber bundle is surrounded by a second fiber bundle comprising acrylate fibers. These two effects act on the manufacture of high quality composite yarns. Further, the high-quality composite yarn according to the fifth aspect of the present invention - the acrylate fiber supplied by the monofilament and the domain fiber supply component supplied by the entanglement via the supply yarn guide, and the natural and / or a synthetic fiber bundle to form a fiber bundle, while tensioning to a monofilament by a tension mechanism such as a tension roller, and twisting the fiber bundle produced in the foregoing step with a monofilament surrounding the yarn passing through the yarn guide roller from the outside of the front roller The bundle is manufactured without supplying force to the monofilaments. In this method, the monofilaments supplied from the outside of the front roller cover almost the fiber bundle containing the acrylate fibers. The composite yarn according to the seventh aspect of the present invention is explained in detail. The synthetic fiber constituting the continuous fiber bundle (A) may be any conventional synthetic fiber. Examples of synthetic fibers include polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate monofilaments; polydecylamines such as aliphatic polyamines and aromatic polycondensates; Indoleamine (for example, the roller is used to maintain the first actual inhibition of the second inhibition by the crude fiber supply, and the ester is used in the form of a complete fiber, etc.) -28 - 1374203

Monofilaments of 6 'Nylon 66, etc.; monofilaments of polyolefins such as polyethylene, polypropylene, etc.; monofilaments of propylene or acrylate resins; and the like. Among them, polyester fibers, particularly polyethylene terephthalate fibers, are preferred from the viewpoint of ease of handling and cost. In addition to the conventional polyacetate, the polyester may include a copolymerized vinegar, for example, an acid such as isophthalic acid, adipic acid, sebacic acid, naphthalene residual acid, terephthalic acid, etc.

The copolymer of an isomeric alcohol such as propylene glycol, butylene glycol, diethylene glycol or the like 〇 The fineness of the synthetic fiber is preferably 300 dtex or less. When the fineness exceeds 300 dtex, the fibers may not be sufficiently opened unless a high voltage is used, and thus the manufacturing cost increases. In addition to this, when a synthetic fiber having such a large fineness is used, the composite yarn has a large fineness. The fineness of the synthetic fiber is preferably from 10 to 150 cents, and the best is from 15 to 100 cents.

The synthetic fiber of the continuous fiber bundle (A) may be treated with an oil containing an antistatic agent. Examples of the antistatic agent include alkyl sulfonate, alkylbenzenesulfonate, alkyl sulfate, phosphate ester, and the like. They can be used independently or in combination of two or more. Antistatic agents are commonly used to easily electrically open synthetic fibers. The amount of the antistatic agent is usually from 12 to 0.5% by weight of the oil agent. When the amount of the antistatic agent is less than 12% by weight, the fiber opening properties of the synthetic fiber may not be improved, so that the composite yarn has an unsatisfactory quality. When the amount of the antistatic agent exceeds 50% by weight, the antistatic agent is severely smoked during the stretching process. Antistatic agent -29- 1374203

The amount of Ji^r- is preferably from 15.5 to 40% by weight, more preferably from 18 to 30% by weight. The amount of the oil agent to be applied to the synthetic fiber is preferably 1.1% by weight or less based on the weight of the synthetic fiber. When the amount of the oil agent exceeds 1.1% by weight, the oil agent may drip, although the antistatic effect is increased. The oil agent is applied to an appropriate amount depending on the single fineness of the synthetic fiber. For example, when the single fineness is large, the fiber surface area is reduced and thus a small amount of oil is preferred. When the single fineness is small, the fiber surface area is increased and thus a large amount of oil is preferred. In the embodiment of the present invention, when the single fineness is from 1 to 2.5 cents, the amount of the oil agent is preferably from 〇. 2 to 1.1%, more preferably from 〇. 3 to 0.9. %, especially good from 0.4 to 0.7%. In this range, the fibers are preferably opened or opened. When the oil is applied to the synthetic fibers, the fibers can be effectively opened. In order to properly evaluate the fiber opening properties of the synthetic fibers, it is preferred to use electrical resistance at 25 ° C and 40% RH. When the synthetic fiber has a resistance of 8 X 1 Ο 8 Ω or less at 25 ° C and 40% RH, it has good fiber-opening properties even if it contains carbon black. When the electric resistance exceeds 8 χ 108 Ω, the fiber opening becomes less uniform, so that spots are likely to occur when the continuous fibers are combined with the discontinuous fibers to form a composite yarn. In order to achieve a resistance of 1 x 10 4 Ω, a relatively large amount of oil, i.e., an antistatic agent, should be applied to the synthetic fiber and the fiber opening property is easily deteriorated. Therefore, the resistance is preferably from 1 X 105 Ω to 6 χ 108 Ω, more preferably from 1 χ 106 Ω to 4 χ 108 Ω. Specific examples of the antistatic agent include poly(oxyethylene)alkylamine, poly(oxyethylene)alkylguanamine, poly(oxyethylene)alkyl ether, poly(oxyethylene)alkylphenyl ether, Glycerol fatty acid ester, sorbitan fatty acid ester, alkyl-30-1374203

Supplementing sulfonate, alkyl benzene sulfonate, alkyl sulfate, alkyl sulfate, alkyl phosphate, ammonium quaternary ammonium chloride, ammonium quaternary ammonium sulfate, ammonium quaternary ammonium nitrate, alkyl betaine, alkyl Imidazoline, alkylaniline, and the like. They can be used independently or as a mixture of two or more. Among them, anionic antistatic agents such as alkylsulfonates, alkylbenzenesulfonates, alkyl sulfates, alkyl phosphates and the like are preferred. In particular, a sulfonate metal salt is preferred. The oil agent to be applied to the synthetic fiber preferably contains 40 to 70 parts by weight of the oil component, 5 to 30 parts by weight of the emulsifier and 12 to 50 parts by weight of the antistatic agent. When the amount of the oil component is less than 40 parts by weight, the coefficient of friction between the fiber and the metal or ceramic part in contact with the fiber becomes too large and may be the cause of the pile. When the amount of the emulsifier is less than 5 parts by weight, when the oil is diluted with water, it may be unevenly mixed with water. Therefore, the oil agent forms spots on the yarn and the yarn also has a tendency to fluff or break. More preferably, the oil agent contains 50 to 60 parts by weight of the oil component, 10 to 20 parts by weight of the emulsifier and 18 to 30 parts by weight of the antistatic agent. As the base oil component to be used in the oil agent of the present invention, a conventional oil component can be used. For example, a suitable mixture of mineral oil and fatty acid ester can be used. The emulsifier may also be a conventional emulsifier, and examples thereof include glycerin fatty acid ester, sucrose fatty acid ester, sorbitan fatty acid ester, propylene glycol fatty acid ester, POE ether-addition product oil, PEG ester-addition. Oil, lecithin, etc. They can be used in their mixture. Among them, PEG dioleate, fatty acid alcohol and their metal salts are particularly preferred. -31 - 1374203 Year Λ β

Supplement I The synthetic fibers used in this embodiment preferably comprise fine particles. These fine particles can reduce the smoothness or slipperiness of the fiber surface, but the use of the oil agent optimizes the friction coefficient and improves the fiber opening properties. The fine particles may be any fine particles such as a pigment, a matting agent, an antibacterial agent, an antistatic agent and the like which are usually mixed in the fiber. Fine particles colored with carbon black are preferred because the fibers comprising the fine particles have good fiber-opening properties, so that spots caused by fiber mixing are suppressed and the pigmented stomach I is reduced. The fibers may contain additives such as matting agents, antibacterial agents, and antistatic agents other than those exemplified above, as well as other polymers. In addition to carbon black, the pigment can be any pigment having other colors. In order to add the fine particles to the fibers, in the case of carbon black, a mixed color body containing 5 to 40% by weight of carbon black and a synthetic resin and a matrix polymer not containing a synthetic resin containing carbon black are mixed and melted. Spinning to obtain a black dyed polyester fiber. In this case, the amount of carbon black is usually from 0.5 to 2.0% by weight based on the weight of the fiber. When the amount of carbon black is less than 0.5% by weight, the stain becomes noticeable. When the amount of carbon black exceeds 2.0% by weight, the carbon black cannot be well mixed with the polymer, so the unevenness becomes People pay attention. The concentrated body and matrix polymer can be mixed by any conventional method. For example, the 'dark color granules and the matrix polymer granules are mixed before melting, and then the mixture is melted. Alternatively, the concentrated body particles and the matrix polymer particles are separately melted, and then the melt is statically mixed only with a static mixer before the wire is cut. After mixing, the mixture is processed by a conventional melt spinning method to obtain fibers. The cross section of each fiber may have any shape such as a circular shape and a deformed (side) shape -32-1374203

, hollow shape, etc. The carbon black used in the present invention may be a channel black, a furnace or the like. When the carbon black main particle size is too small' when the carbon black particles are mixed with a polyester such as a polyethylene terephthalate type copolyester, they tend to aggregate and the spinning of the mixture may be difficult. When the primary particle size of carbon black is too large, the depth of black is reduced. Therefore, the main particle size of the carbon black is preferably from 10 to 40 nm. When the main particle size is less than 10 nm, the treatment of carbon black is difficult. When the main particle size exceeds 40 nm, the back pressure in the nozzle increases during the spinning, so that the workability is deteriorated due to yarn breakage or the like. a discontinuous fiber bundle (B) comprising natural fibers and/or synthetic fibers, which is supplied from a crude fiber supply component, preferably comprising wool, cotton, silk, hemp linen, ramie, synthetic fiber staple fibers, staple fibers, The acetate cuts the fibers and mixtures thereof. Among them, wool is better. The composite yarn according to the seventh aspect of the invention preferably has a raised number of i 000 fluffs/10 m or less for fluff having a length of at least 1 mm. In order to produce a high quality fabric, the number of raised yarns is preferably 700 fluffs / 10 m or less. When the number of fluffs is large, the portion of the fabric concentrated fluff sees white after dyeing of the fabric, and thus the quality of the fabric is remarkably reduced. The composite yarn according to the seventh aspect of the present invention can be manufactured as follows: It is substantially in a bundled state, is entangled with the fiber bundle to be stretched, and then twisted and wound, or temporarily twisted to form a yarn having a wound pile - or 'stretched fiber bundle and fiber open fiber multifilament Wrap them together, then twirling and winding them, or temporarily twisting to form a yarn with entangled fluff -33-1374203

Further, the high-quality composite yarn according to the seventh aspect of the present invention can be obtained by winding a fiber bundle of natural and/or synthetic fibers with a monofilament (A) fiber bundle supplied from a monofilament supply assembly via a supply yarn guide. Forming a fiber bundle while supplying tension to the monofilament with a tension mechanism such as a tension roller, and twisting the fiber bundle generated in the foregoing step while twisting the fiber bundle (B) passing from the outside of the front roller through the yarn guide roller without supplying tension to Made from these monofilaments.

In this method, the monofilaments supplied from the outside of the front roller completely cover the fiber bundle (B). In addition to the above methods, the composite yarn can be produced by continuously opening the synthetic fiber-dimensional monofilament (A). In order to charge the synthetic fiber monofilament (a) and the unbroken open fiber monofilament, a truncated electrode as disclosed in JP-A-47-1 1247 can be used. In addition to using a fiber-fibrating electrode, the fiber can be corona-discharged and ionized with an air medium, or opened or opened by contacting the fiber with a high voltage electrode. The continuous synthetic fibers (A), which are supplied from a monofilament supply unit and are opened by using an electric fiber opening device, and a fiber bundle (B) of natural and/or synthetic fibers, which are supplied from a crude fiber supply unit, Entangled, then twist them to obtain high quality yarns (with a number of fluffs of 700 fluff / 10 〇〇 m or less). The position at which the continuous synthetic fiber (A) and the discontinuous fiber bundle (B) are supplied can be adjusted by controlling the positional adjustment of the fiber-opening electrode or by using a special yarn guide of the open-fiber monofilament. The fiber opening width of the continuous synthetic fiber (A) can be adjusted by controlling the voltage, the strength of the supply, the special yarn guide of the monofilament, and the like. -34- 1374203 ... Supplemental The continuous and discontinuous fiber composite yarn of the present invention can be produced using the apparatus shown in Fig. 2. In order to produce a continuous and discontinuous fiber composite yarn, the multifilament A is unwound from the tweezers 8 and passed through the yarn guide 9 to the electrode 6. . The electrode 6 is a hollow electrode and supplies static electricity to the multifilament A, which is passed through the electrode 6, so that the yarn is expanded into individual filaments. The charged multifilament is passed through the yarn guide ring 7 and then supplied to the front roller 3 while adjusting the fiber opening width and the supply position. Separately, the coarse discontinuous fibers B are supplied to the rear roll 1 and then stretched between the carrier 2 and the front roll 3. Thereafter, the discontinuous fibers B are supplied to the front roller 3 in the form of a bundle of the discontinuous fibers B. Then, the multifilament A, which has been opened or opened, and the bundle of the discontinuous fibers B are mixed or entangled at the nip of the front roll 3. At this stage, the center of the multifilament A is substantially aligned with the center of the discontinuous fiber bristles while limiting the fiber opening width of the multifilament to 50 to 300% of the maximum width of the discontinuous fiber bristles. A mixture of multifilament A and discontinuous fiber bristles, which is passed through a front roll 3, is twisted to form a yarn structure having a cross section composed of a uniform mixed layer of monofilaments and discontinuous fibers. Finally, the twisted yarn passes through the volute guide 4 and is then wound on a winding machine 1 having a ring and a bead ring 5. In the composite yarn according to the seventh aspect of the present invention, the discontinuous fiber bundle (B) and the continuous synthetic fiber (A) having good fiber-opening properties are uniformly mixed. Therefore, the composite yarn has a small amount of fluff and a uniform salt of different colors when the synthetic fibers (A) are dyed fibers of the spinning liquid -35-1374203

MM appearance. In addition, since the number of fluffs is small, the yarn has improved weaving properties. The composite yarn can be processed into the form of plain weave, twill fabric, satin or the like, or knitted, for example, in the form of warp knits and weft knits. These fabrics have good deep dyeing properties, are not stained with small spots, and are also improved in texture, and are particularly suitable for sewing black dresses. In the synthetic fiber according to the eighth aspect of the present invention, the oil agent containing 12 to 50% by weight of the antistatic agent is attached to the fiber at 11% or less of the total weight of the fiber, and the fiber is at 25 ° C and 40% RH has a resistance of ·8 X l〇8Q or less. The synthetic fibers used in connection with the above specific examples are conventionally known. - Examples of synthetic fibers, and synthetic fibers are the same as those of the continuous synthetic fibers (A) of the composite yarn according to the seventh aspect of the present invention. The oil agent containing an antistatic agent, the amount and electric resistance of the oil agent to be used in this embodiment are the same as those explained in the composite yarn according to the seventh aspect of the present invention. The synthetic fiber used in this embodiment preferably contains fine particles. These fine particles improve the smoothness or slipperiness of the fiber surface, but the use of an oil agent optimizes the friction coefficient and improves the fiber opening properties. The fine particles may be any fine particles such as a pigment, a matting agent, an antibacterial agent, an antistatic agent and the like which are usually mixed in the fiber. Fine particles colored with carbon black are preferred because the fibers comprising the fine particles have good fiber-opening properties, so that spots caused by fiber mixing are suppressed and the color spots are reduced. The fibers may contain additives such as matting agents, antibacterial agents, and antistatic agents other than those exemplified above, as well as other polymers. In addition to carbon black, -36-

1374203 The pigment can be any pigment of other colors.

In order to add the fine particles to the fibers, in the case of carbon black, a mixed color body containing 5 to 40% by weight of carbon black and a synthetic resin and a matrix polymer not containing a synthetic resin containing carbon black are mixed and melted. Spinning to obtain a black dyed polyester fiber. In this case, the amount of carbon black is usually from 0.5 to 2.0% by weight based on the weight of the fiber. When the amount of carbon black is less than 0.5% by weight, the stain becomes noticeable. When the amount of carbon black exceeds 2.0% by weight, the carbon black cannot be well mixed with the polymer, so the unevenness becomes noticeable. .

The concentrated body and matrix polymer can be mixed by any conventional method. For example, the concentrated body particles and the matrix polymer particles are mixed prior to melting, and then the mixture is melted. Alternatively, the 'dense color body particles and the matrix polymer particles are melted separately, and then the melt is statically mixed only with a static mixer before the wire is cut. After mixing, the mixture is processed by a conventional melt spinning method to obtain fibers. The cross section of each of the fibers may have any shape such as a circular shape, a deformed (lateral) shape, a hollow shape or the like. The carbon black used in the present invention may be any of the conventionally used carbon blacks. These types and particle sizes have been explained. The fineness of the synthetic fiber can be explained in the same manner as the synthetic fiber according to the seventh aspect of the present invention. The electric fiber fiber opening device according to the present invention will now be explained by referring to the drawings. <First embodiment of fiber opening device> -37- 1374203

Fig. 3 schematically shows a cross section of a first embodiment of an electrical fiber opening device according to the present invention. The fiber opening device 1 comprises a body 2 made of an insulating material which is provided in the fiber running direction and has a specific length in this direction. Further, the fiber opening device 1 has a hollow cylindrical electrode 3 which passes substantially along the central axis of the main body 2. The electrode 3 is connected to a power source 4 which supplies a voltage to the electrode 3. The multifilament passes through the hollow portion of the electrode 3 to charge the yarn"

The fiber opening device 1 has a cover member 5 which is made of an insulating material and is provided on the rear side with respect to the running direction of the yarn. The cover member 5 has an opening through which the yarn is introduced into the electrode 3. In addition to this, the fiber opening device 3 has a grounding ring 6 on the front side with respect to the running direction of the yarn. The ring 6 is provided such that the central axis of the ring 6 is substantially parallel to the central axis of the electrode 3. The inner diameter of the rear end 6A of the grounding ring is larger than the outer diameter of the yarn outlet 3B of the electrode. Preferably, the inner space of the ring 6 has a truncated cone shape, wherein the inner diameter of the front end 6B is larger than the inner diameter of the rear end 6A. As shown in Fig. 2, the fiber opening device 1 is usually mounted along a vertical line, so that the multifilament is conveyed downward and stably opened or opened, that is, the cover member 5 faces upward and the ground ring 6 faces downward. However, the fiber opening device 1 can be mounted in any direction except for the vertical direction. The electrode 3 for supplying a voltage has a hollow cylindrical shape, so the multifilament can pass through the electrode. The cross-sectional shape of the electrode 3 in a plane perpendicular to the running direction of the yarn is not limited, but is preferably circular so that the electrode does not interfere with the operation of the yarn. In order to maintain a stable opening of the multifilament, the length of the electrode 3 is usually from 15 to 70 mm, preferably from 20 to 60 mm, more preferably from 25 to 50 mm -38 to 1374203.

The inner diameter of the electrode 3 is usually from 〇·3 to 6 mm, preferably from 0 5 to 3 mm, more preferably from 0.8 to !J 2 mm. Using the fiber opening device 1, a voltage is supplied from the power source 4 to the electrode 3 and the multifilament which is sequentially charged by the electrode 3 through the electrode. The material of the electrode 3 is not limited as long as the electrode 3 can be charged with a multifilament. Examples of the material of the electrode 3 include conductive metals such as iron, copper, silver, etc., and other conductive materials such as conductive plastics, including plastics or ceramics in which metal powder or the like is mixed.

The grounding ring 6 provides a downflow in the direction of the electrode 3 relative to the yarn transport fj. Ring 6 is connected to the ground and has a substantially zero potential. Since the multifilament is charged through the electrode 3 and then passed through the grounding ring 6, the charging monofilament of the multifilament is attracted by the grounding ring 5. Thereby, the fiber can be opened. The material of the grounding ring 6 is not limited as long as the charging monofilaments are attracted. Examples of the material of the ring 6 include conductive metals such as iron, copper, silver, etc., and other conductive materials such as conductive plastics, including plastics or ceramics in which metal powder or the like is mixed.

In order to facilitate the fiber opening of the multifilament, it is preferred that the internal space of the grounding ring 6 is shaped such that it forms a front end of the space which flows downstream with respect to the direction of travel of the yarn, greater than the rear end of the space, which is present in the direction of travel relative to the yarn. The cross-sectional shape of the grounding ring 6 in a plane perpendicular to the running direction of the yarn is not limited, but is preferably circular so that the multifilaments can be opened or opened evenly in the direction of all the cross-sections. In order to stably open the multifilament, the inner diameter of the front end 6 of the grounding ring 6 is usually from 6 to 25 mm, preferably from 8 to 22 mm, more preferably from 10 to 20 mm, and the inner diameter of the rear end 6A is usually from 5 to 24 mm, preferably from 6 to 20 mm, more preferably from 7 to 15 mm. -39- between front end 6B and back end 6A

The supplemental I distance is usually from 3 to 25 mm, preferably from 5 to 20 mm, to 15 mm. The yarn exit 3B of the electrode exists between a position 5 mm in the reverse direction of the conveyance of the rear end 6A of the grounding ring and a position 23 mm from the direction in which the rear end 6A of the grounding ring is conveyed. Preferably, the enthalpy of the electrode is present between the reverse 3 of the grounding ring rear end 6A with respect to the yarn delivery and the direction 20 of the grounding ring rear end 6A with respect to the delivery of the yarn. More preferably, the yarn exit 3 B of the electrode is present at a position 18 mm from the ground write direction with respect to the yarn transport direction. The pole yarn inlet 3A is present in the opposite direction of the grounding ring rear end 6A, and the yarn exiting electrode 3B is present in the grounding ring. The flow direction is opposite to the yarn running direction. Preferably, the electrode 3 of the fiber opening device 1 is surrounded by the insulating material main body 2, and the cover member 5 having the yarn introduction opening (which is also manufactured) and provided in the direction of the # in the direction of the yarn running through the electrode. 3 back side. In this way, workers do not encounter electrodes to improve safety. In the fiber opening device 1, the main body 2 and the cover can be unnecessary components. The voltage supplied to the electrode 3 can be positive or negative. The absolute enthalpy supplied to the voltage is typically from 1 to 20 kV, preferably from 1 to 1 i preferably from 2 to 7 kV. The rate at which the multifilament passes through the electrode is usually from 0.03 to 0, preferably from 0.05 to 0.55 m/sec, more preferably from 0.07 to 0. In this regard, the rotation rate of the turns of the wound multifilament is generally better from 7 to the rear end 6A of the wing of the bit 3 mm relative to the yarn with respect to the yarn, and the t-front 6B of the yarn running is manufactured. The hollow channel 3 of the insulating material and thus the component 5 can be electrically 0 kV, more than 70 m / sec 4 5 m / sec L from 3000 - 40 - 1374203 interesting month to 1 5,000 rpm, preferably from 40 υυ $ Ij 1 3,000 rpm, preferably from 5000 to 1 1,000 rpm. The tension applied to the multifilament is 10 gf (gram-force) or less, preferably 5 gf or less, more preferably 2 gf or less. The multifilament is a continuous fiber comprising synthetic fibers which has been described in relation to the composite yarn according to the invention. <Second embodiment of fiber opening device> When the fiber opening device of the first embodiment is used, the multifilament can be completely opened or opened and the yarn of the early filament and the electrode is opened The outlet is constantly in contact, causing the electrode to be subject to wear. When a hard tube having an inner diameter of its yarn inlet equal to or larger than the inner diameter of the yarn outlet of the electrode is connected to the yarn outlet of the electrode, the expanded filaments are not directly in contact with the electrode and thus prevent abrasion of the electrode. In principle, the hard tube is connected to the electrode so that the hard element is in contact with at least the yarn outlet front end of the electrode to prevent the open monofilament from coming into direct contact with the yarn exit of the electrode. The hard tube is typically hollow with a yarn inlet and a yarn outlet of the same inner diameter. Cylinder. However, the inner diameter of the inlet and outlet of the yarn of the hard tube may be slightly different as long as the monofilament is prevented from coming into contact with the yarn outlet of the electrode. In one implementation of the second embodiment of the fiber opening device, the yarn exit of the electrode is joined or inserted into the yarn inlet of the hard tube so that the yarn exit of the hard tube is carried over the electrode outlet in the running direction of the yarn. Fig. 4 is a schematic enlarged cross-sectional view showing the voltage supply electrode 3 and the hard tube 7 of the fiber opening device of the embodiment near the yarn exit. On the connection -41 -

The distance between the yarn outlet 3B of the 1374203 or the electrode inserted into the hard tube 7 and the yarn outlet 7B of the hard tube 7 is usually 10 mm or less, preferably 7 mm or less, more preferably 4 mm or less. Preferably, the rigid tube 7 is made of a hard material that is sufficiently resistant to contact with the multifilament. For example, the hard tube is made of a hard material such as ceramic or stainless steel, or a material having an inner surface coated with a hard layer such as diamond or tantalum carbide. A larger portion of the electrode 3 is inserted in the hard tube to protect the electrode 3. In this case, the electrodes are inserted in the hard tube at a distance from the external power supply voltage to the electrodes. When a larger portion of the electrode 3 is inserted into the hard tube 7, for example, the rear portion of the electrode 3 with respect to the direction in which the yarn runs is not inserted in the hard tube 7 to leave an exposed portion connected to the power source. Alternatively, a window and a window are formed in the middle portion of the hard tube 7. The electrode 3 is connected to the power source through the window. In order to prevent the electrode from being worn by the open filament of the multifilament, at least the inner surface of the outlet region of the electrode 3 may be made of a hard material instead of the use of the hard tube. For example, the inner surface of the electrode is coated with a hard layer such as diamond or carbonized sand.
