Description

(1) 200417640 发明. Description of the invention [Technical field to which the invention belongs]

The present invention relates to a novel composite yarn comprising continuous fibers and discontinuous fibers, which are entangled (or mixed) with stretched discontinuous fiber bundles and opened (or spread or divided into individual pieces) by winding the composite yarn Monofilament), a multifilament of synthetic fibers, and the actual twisting of them, a method for making composite yarns, a cloth or fabric containing composite yarns, and a fiber opening device for making composite yarns. [Prior art] To date, the following methods are known as methods for compounding discontinuous fiber bundles and multifilaments: (1) a multifilament, which is substantially bundled and entangled with a stretched discontinuous fiber bundle, And twisting and winding them (1 -1) or temporarily twisting and bundling them to form a fluffed yarn (1-2); (2) the stretched fiber bundles are opened in multifilament Wind, then twist and twist them (2-1), or twist and bunch them temporarily to form a tangled yarn (2-2). However, the method (1-1) has disadvantages in that the number of twists of a conventional yarn composed of cut fibers is applied to improve the entanglement of the drawn discontinuous fiber bundle and the multifilament. The method (1-2) has disadvantages: because the discontinuous fibers and multifilaments cannot be fully entangled only by temporary twisting and bundling, they should be glued, fused or moderately twisted. The method (2_1) has disadvantages: the twisted and wound yarn has a tacky appearance -5- (2) (2) 200417640 or sparkling appearance, although it has uniformity. In the method (2.2), the multifilament is excessively loosened or stretched, so that the cut fiber does not sufficiently function to surround the fluff, and thus the longitudinal bundle state is uneven in many cases. A method including entanglement to make fiber bundles and bulky threads is proposed (for example, JP-A-49- 1 0 1 63 9). However, this method has disadvantages. The yarn has a poor appearance because the fiber bundle should be manufactured in an over-feed state and high-speed rotary spraying is used to easily form fiber knots and spots. In addition, a composite yarn including a monofilament component and a discontinuous fiber component is proposed in which a monofilament component in an actual twisted state exists in a core portion and a discontinuous fiber component exists in a cortex portion (for example, JP-A- 59-3 0925 and JP-A-6 1 -23 903 6). However, this composite yarn has an insufficient appearance of pepper and marble when it is dyed in different colors, has a large number of small spot stains in the case of deep dyeing, and causes a lot of trouble when it is knitted. Among synthetic fibers, acrylate fibers are attractive because they have excellent functions (temperature-control., Moisture-control, tempering). Taking advantage of these characteristics, blended yarns of acrylic fibers and other materials are used in sports and interior applications. However, acrylate fibers only have a strength of 0.55 to 1.82 g / d and a non-strength of 0.30 to 1.5 d / g. Therefore, when acrylate fibers are blended with other materials, they are damaged and discontinuous fibers break and the fibers fall. When the percentage of acrylate fibers in mixed yarns increases, these shortcomings of acrylate fibers become apparent. (3) (3) 200417640 When the percentage of acrylate fibers in mixed yarns decreases, the above disadvantages can be overcome. The characteristics of the fiber are greatly deteriorated, which is a fatal problem. Therefore, the conventional mixed yarn containing acrylate fiber is problematic from the viewpoint of yarn properties and yarn quality. In particular, due to the nature of acrylate fibers and damage to acrylate fibers during processing, the strength of the yarn is greatly reduced. Therefore, the percentage of acrylate fiber in the mixed yarn is greatly limited. In addition, the yarn count is limited to a large yarn count. With regard to yarn quality, the breakage of discontinuous fibers, which occurs in the processing of acrylate fibers, increases the number of fiber knots generated during spinning and further increases the number of regions where the fiber knots are concentrated in the longitudinal direction of the yarn. Therefore, the yarn quality is significantly reduced. When the fabric containing these yarns is dyed, the area where the fiber knots are concentrated is white, so the quality of the fabric is also greatly reduced. Therefore, hybrid yarns containing these acrylic fibers are used on the back side of fabrics, or in applications that do not require high-quality fabrics. When using them in consideration of the properties of acrylate fibers, when dyeing, it is often attempted to hob the acrylate fibers to a short length and coat the honed fibers with paint or the like. From the viewpoint of application of functional properties, this method is excellent because the acrylic fiber is coated with a paint or the like, the texture of the fabric is hardened and the thickness of the fabric is increased. As a result, the inherent texture of the fabric is impaired. Therefore, this method can be used in limited applications. Over the years, there has been a great need for high-quality sports-interior fabrics that take advantage of the high functional properties of acrylic fibers. However, as explained above, it is difficult to give the fabric the high functional properties of the acrylic fiber by increasing the percentage of the acrylic fiber in the mixed yarn. Therefore, one (4) 200417640 composite yarn containing acrylate fibers has not been provided. To prepare a composite yarn, an electric fiber opening method is known (for example, JP-A-54-17063 and U.S. Patent No. 3,657,871). A double-layer yarn and a composite yarn including a fiber bundle and a single monofilament are also known (for example, JP-A-6-22 8 8 3 8 and JP-A-2000- 1 75 32). However, these patent publications do not disclose composite yarns containing acrylate fibers.

A composite yarn of continuous and discontinuous fibers is supplied as a mixed yarn of various fibers and manufactured by various composite methods. However, composite yarns of continuous fibers and discontinuous fibers are not known, which contain dope-dyed fibers to improve the texture or hue. When these dope-dyed fibers are used, some problems arise: the dope-dyed fibers have irregularities because of the uneven mixing encountered in the manufacture of the dope-dyed fibers, or during processing such as Knitting quills or tailor needles are worn by fine particles of the original colorant.

As dope-dyed yarns, such synthetic fibers as polyester, polyamide, etc. are known, which contain mixed colored particles such as pigments. However, it is not known to perform fiber opening on these yarns. In particular, black polyester fibers manufactured by dope dyeing (hereinafter referred to as "spin dope black dyed fibers") are made by adding carbon black in the polymerization method or any step after the polymerization to the fiber-forming step. To polyester (for example, JP-A-8- 1 3 248). However, when the composite yarn is manufactured by opening the dope 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 stains and cannot be used for woven fabrics used for making dresses (or gowns). When these fibers are not When evenly opened, the stain is more prominent in the fabric containing these fibers. -8- 200417640

When the composite yarn is prepared as described above, the device for electrically opening or opening fibers is a known device for opening multifilaments. For example, j P _ υ Μ (utilization model) -5 0 · 93 66 Α discloses a device using the multifilament through a hollow cylindrical electrode for supplying a voltage and then electrically charging the wire and opening through a ground ring. Loosen or spread the fiber, and JP-UM-50-35149A discloses a device using the device 'to spray a pressurized liquid on a multifilament wire, which is then passed through a hollow cylindrical electrode for supplying voltage and then through ground The loop charges the filament electrically and opens the fiber. The degree of fiber opening of the multifilament using this type of electrical fiber opening device depends on the tension applied to the yarn, environmental conditions (eg, temperature, humidity, etc.), the type of multifilament, and so on. For example, as the speed of multifilament movement 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 wire, and the tension on the wire should be determined based on the experience of the worker or preliminary experiments to achieve a stable degree of fiber opening regardless of changes in the preparation conditions. Therefore, an electric fiber opening device capable of achieving a stable degree of fiber opening and ignoring changes in production conditions has been sought to improve manufacturing efficiency. This type of fiber opening device allows the multifilament to pass through a hollow cylindrical electrode for supplying a voltage to charge the yarn and unwind the fibers. Therefore, when the fibers of the multifilament are completely opened, the opened fibers continuously contact the fiber outlet of the electrode, so the fiber outlet tends to wear. That is, when the multifilament is fully opened, the worn electrode should be replaced from time to time, which causes another problem that the manufacturing efficiency is reduced by stopping the manufacturing to replace the electrode. -9- 200417640

DETAILED DESCRIPTION OF THE INVENTION First, a continuous and discontinuous fiber composite yarn according to a first aspect of the present invention and a method for manufacturing the same are explained by referring to the drawings. The drawings are provided to illustrate the present invention and are not intended to limit the scope of the invention. The composite yarn of discontinuous and discontinuous fibers of the present invention comprises a multifilament of synthetic fibers and discontinuous fibers, which are opened and mixed by the fibers. Figure 1A shows the cross-sectional structure of a composite -14- (11) 200417640 yarn, in which the central portion contains a homogeneous mixture of multifilaments composed of synthetic fibers and discontinuous fibers, and the peripheral portion contains discontinuous fibers surrounding the central portion . The discontinuous fiber composite yarn having this structure can provide a fabric with light weight and less translucency, and when the yarn is knitted or knitted, and the fabric containing the yarn has a deep dyeing property when the fabric is used to sew a black dress And less stained small spots.

Preferred examples of the synthetic fibers constituting the composite yarn include polyester fibers, poly (trimethylene terephthalate) fibers, polyamide fibers, polyolefin fibers, polyacrylonitrile fibers, polybutylene terephthalate fibers, and the like mixture. Among them, polyester fiber is more preferable. Preferred examples of the discontinuous fibers constituting the composite yarn include wool, cotton, silk, hemp, linen, ramie, synthetic fiber cut fibers, staple fibers, acetate cut fibers, and mixtures thereof. Among them, the multifilament of wool, which is a better synthetic fiber and discontinuous fiber, is opened and mixed to increase the entanglement of the multifilament discontinuous fiber and to sequentially improve the post-processing properties of the yarn. Mixing indicates the presence of multifilament and discontinuous fibers in a mixed state. In particular, the multifilament and discontinuous fibers are uniformly mixed in the center portion of the yarn so that the degree of entanglement of the multifilament and discontinuous fibers is high in the center portion. Therefore, the yarn has good weaving properties. At the same time, the discontinuous fiber layer surrounds the uniform layer in the central part so that the yarn has a protruding structure, so fabrics made from this type of yarn have a lightweight, less translucent, and wool-like texture. Preferably, the multifilament of synthetic fibers has a fineness of 11 to 110 dtex. -15- (12) (12) 200417640 When the composite yarn does not have a thickness within a certain range, it is not accepted in the market. 〇 When the fineness of the multifilament is less than 11 dtex, the composite effect may not be achieved. When the fineness of the multifilament exceeds 110 dtex, fabrics made from yarn may lose wool feel. The above range of fineness is desirable for making a marketable fabric having a wool feel. In order to impart a texture to the wool of the fabric, each of the monofilaments preferably has a fineness of 0.1 to 6.6 dtex, and more preferably 0.2 to 3.3 dtex. When the fineness of each monofilament is less than 0.1 dtex, the fabric may lose stardiness. When the fineness of each monofilament exceeds 6.6, the texture of the fabric may be far from the wool-like texture. When using artificial staple fibers other than natural fibers as discontinuous fibers', they may be cut into equal lengths or cut into unequal lengths. The average length of rayon staple fibers is better, from 50 to 150 mm for fabrics with wool warmth, or from 25 to 50 mm for fabrics with cotton warmth. The amount of the 'discontinuous fiber' in the composite yarn is preferably from 50 to 95% by weight, based on the total weight of the yarn. When the amount of the discontinuous fibers is less than 50% by weight, it may be difficult to surround the homogeneous mixture layer of the discontinuous fibers and the multifilament with a discontinuous fiber layer. When the amount of discontinuous fibers exceeds 95% by weight, the entanglement of the 'multifilament and discontinuous fibers may deteriorate. The composite yarn according to the first aspect of the present invention preferably has a fluffing rate of 300 to 900 fluffs per 100 m of fluff having a length of at least 1 mm. More preferably, it has a fluffing rate of 80 to 200 fluffs per 10 m of fluff having a length of at least 3 mm. When the raising rate is within the above range, fabrics made from composite yarns have a light weight, less translucency, and a wool-like texture. Here, the fluff rate was measured using an F-rate tester manufactured by Shikibo Co., Ltd. When looking at the cross section of the composite yarn, it is generally seen that the central part is composed of a homogeneous mixture of multifilaments of synthetic fibers and non-continuous fibers, while the peripheral part contains discontinuous fibers and surrounds the central part. This structure is a characteristic of the composite yarn of the first aspect of the present invention. The composite yarn of the first aspect has a good entanglement of monofilaments and discontinuous fibers and a wooly feel and can provide a woven fabric having light weight and less translucency. In addition, when composite yarns are used to make black dress fabrics, the fabrics have deep dyeing properties and have fewer stains and small spots. Therefore, fabrics are suitable for sewing men's clothing, gowns, high-quality ladies' or women's blouses. The lightweight fabric according to the present invention can be adjusted from 35 to 47, preferably from 38 in the case of plain weaves, by using the continuous and discontinuous fiber yarns as the warp and / or weft and adjusting the average count factor of the warp and weft. To 45, or in the case of twill, from 45 to 50, preferably from 48 to 57. Here, the plain weave means a plain weave structure of one of the three primary tissues, and includes a modified plain weave such as a heavy plain weave, a matte weave, and the like. Twill fabric means any fabric with a twill structure that is one of the three original tissues, and includes modified twill such as sharp twill, diagonal twill and the like. In the case of plain fabrics, when the average count factor is less than 35, the fabric has large translucency and may lose practical properties. When the average count factor exceeds 47, the fabric may not have sufficient air permeability. In the case of twill fabrics, when the average count factor is less than 45, the '-17- (14) 200417640 fabric may lose practical properties. When the average count factor exceeds 60 ', the woven fabric may not have sufficient air permeability. The average count factor is calculated as follows: The count factor T of the warp yarn is calculated as follows: T = (number of warp yarns / 10cm mesh) / (count) 1/2 count factor T of the weft yarn is calculated as follows:

T = (㈣: number of yarns / 10cm) / (count) 1/2, then the average count factor is calculated by the following formula: Average count factor = (T + W) / 2 It is preferably at least 50 cc / cm2 / sec, and more preferably at least 90 cc / cm2 / sec. When the air permeability is less than 50 cc / cm2 / sec, the fabric may lose ventilation-radiation properties, so it may not provide a cool or fresh feeling. The air permeability can be measured with a Furajal tester. The above-mentioned composite yarn having the special cross-sectional structure of the present invention can be manufactured as follows: The multifilament yarns of synthetic fibers are electrically opened or expanded into individual multifilaments. Then, the spread multifilament is tangled with the discontinuous fiber drawn only in front of the front roll. At this point, the center of the spread multifilament and the center of the discontinuous fiber hair are aligned. In addition, the fiber opening width of the multifilament is controlled by the supply tension or fiber opening voltage or by using a special yarn guide so that the mixed layer of the multifilament fiber and a part of the discontinuous fiber are concentrated in The composite yarn is narrowed while the remaining discontinuous fibers surround the mixed layer. In the method for manufacturing a composite yarn according to the present invention, when they are tangled or mixed only before the front -18- (15) 200417640 roll, the fiber opening width of the multifilament should not exceed the maximum width of the discontinuous fiber hairs. When the fiber opening width of the multifilament exceeds the maximum width of the discontinuous fiber hairs, a yarn structure in which the discontinuous fibers surround a uniform mixture layer of the monofilaments and the discontinuous fibers cannot be obtained. Therefore, since the raising effect of the monofilament is increased, it is not possible to manufacture a lightweight fabric having less translucency.

The fiber opening width of the multifilament of synthetic fibers is usually equal to or smaller than the maximum width of the discontinuous fiber hairs, preferably from 10 to 60% of the maximum width of the discontinuous fiber hairs. Thereby, the homogeneous mixture layer of monofilaments and discontinuous fibers constitutes the central portion of the composite fiber and the remaining discontinuous fibers surround the central portion. Therefore, specific structures and effects of the yarn can be achieved, for example, improved weaving properties, manufacture of lightweight and less translucent fabrics, deep dyeing properties, and reduced stain spots.

When the fiber opening width of the multifilament of synthetic fibers is less than 10% of the maximum width of the discontinuous fiber hair, the opening effect of these fibers deteriorates, so the weaving properties are reduced to the level of the core yarn, and the above-mentioned invention may not be achieved Effect. The position where 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 opening the monofilament. The fiber opening width of the multifilament can be adjusted by controlling voltage, supplying tension, specific yarn guides for the monofilament, and the like. The continuous and discontinuous fiber composite yarns of the present invention can be manufactured using the apparatus shown schematically in FIG. Referring to FIG. 2, the device includes a rear roller 1, a carriage 2 and a front roller 3, which are assembled in this order of -19- (16) 200417640. Below the front roller 3, a volute thread guide 4 and a winder 10 equipped with a ring and a traveler 5 are provided. Above the front roller 3, a fiber opening electrode 6 and a yarn guide ring 7 are provided in this order from the upper end.

In order to manufacture continuous and discontinuous fiber composite yarns, the multifilament A is unwound from a bobbin 8 and passed through a yarn guide 9 to an electrode 6. The electrode 6 is a hollow electrode and supplies electrostatic charges to the multifilament A, which is passed through the electrode 6, so the yarn is stretched into individual filaments. The charged multifilament passes through the yarn guide ring 7 and is then supplied to the front roller 3 while adjusting the fiber opening width and supply position. Separately 'the coarse discontinuous fibers B are supplied to the rear roll 1 and then drawn between the carriage 2 and the front roll 3. Thereafter, the discontinuous fibers B are supplied to the front roller 3 in a bundle form of the discontinuous fibers B. Then, the multifilament A 'has been opened or splayed, and the wool-like bundle of discontinuous fibers b is mixed or tangled at the nip of the front roller 3. At this stage, the center of the multifilament A is substantially aligned with the center of the width of the discontinuous fiber hair, and the opening width of the fiber of the multifilament A is preferably adjusted to 10 to 60% of the maximum width of the discontinuous fiber hair. A mixture of multifilament A and discontinuous fiber hair, which is twisted through the front roll 3 to form a specific yarn structure such that the cross section of the yarn has a central portion of a uniformly mixed layer of monofilaments and discontinuous fibers and surrounds the center Peripheral layers of partially discontinuous fibers. Finally, the 'twisted yarn passes through a volute guide 4 and is then wound on a winder with a ring and a traveler 5. Next, 'continuous and discontinuous composite yarns according to the third aspect of the present invention, and a method for manufacturing the composite yarn are explained. -20- (17) (17) 200417640 This continuous and discontinuous fiber composite yarn contains multifilaments of synthetic fibers and discontinuous fibers, which are opened and mixed by the fibers, and the composite yarn has a multifilament layer and a discontinuous fiber layer The spirally wound structure, and in each spiral layer, the multifilament layer exists on the outside, while the discontinuous fiber layer exists on the inside, as shown in FIG. 1B. The composite yarn having this structure can provide woven or knitted fabrics with a wooly feel, and improve the salt and pepper pattern when monofilaments and discontinuous fibers are dyed in different colors, and fabrics containing such yarns have deep dyeing properties and are useful as fabrics. When sewing black dresses, there are fewer stains and small spots, and they also have less fluff and good breathability. Therefore, the fabric made from this composite fabric is suitable for sewing men's wear, dresses, high-quality ladies' wear or jackets. Multifilament synthetic fibers and discontinuous fibers may be the same as those used in the manufacture of composite yarns according to the first aspect of the present invention. The description about the fineness of the multifilament yarn and the fineness of each of the yarns' for the composite yarn according to the first aspect of the present invention is applicable 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 wt%, the discontinuous fibers and the multifilaments may be entangled or mixed insufficiently. When the amount of discontinuous fibers exceeds 95% by weight, it may be difficult to manufacture a composite yarn with few spots. The composite yarn according to the third aspect of the present invention preferably has a fluffing rate of at least 2000 to 900 hairs per 100 m of hair length of at least 1 mm. More preferably, in addition to the above-mentioned fluffing rate, it has a fluffing rate of at least 5 to 21-(18) 200417640 fluffs per 10 m or less. When the raising rate is in the above range, a fabric made from a composite yarn has been improved in post-processing properties such as weaving properties to maintain a wool-like texture, and to further improve quality by suppressing formation of fiber knots in a weaving method. Again, the fluff rate was measured using an F-rate tester manufactured by Shikibo.

The characteristic multifilament and discontinuous fibers of the composite yarn according to the third aspect of the present invention are spirally wound. The direction of the spiral can be clockwise or counterclockwise. The direction of the helix can be controlled by the entanglement position of the continuous and discontinuous fiber bundles during spinning. The composite yarn according to the third aspect of the present invention can be used to make the same fabric as the fabric made from the composite yarn according to the first aspect of the present invention, and an explanation of all fabrics made from the composite yarn according to the first aspect of the present invention Suitable for fabrics made from composite yarns according to the third aspect of the present invention.

The composite yarn according to the third aspect of the present invention can be used to electrically open multifilament yarns of synthetic fibers and entangle with discontinuous fibers that are stretched only before the front roller, wherein the maximum opening width of the discontinuous fibers is Η The maximum opening width h of the multifilament with continuous fibers at the entanglement point is such that the distance from the edge point of width 到 to the edge point of width h is entangled with the multifilament and discontinuous fibers. 90% relationship. In the above-mentioned manufacturing method, it is important to change the supply axis of the multifilament yarn of the synthetic fiber and the supply axis of the discontinuous fiber. 'When the fibers of the synthetic fiber are loosened, the multifilament yarn is tangled with the non-continuous fiber drawn only before the front roll . The maximum opening width h of the multifilament of the synthetic fiber is preferably equal to or larger than the maximum opening width H of the discontinuous fiber hair. When the maximum opening width h is smaller than the maximum -22- (19) (19) 200417640 large opening width 毛, the effect of fluffing and opening on a layer having monofilaments is reduced and thus the weaving properties and the quality of the fabric in turn are deteriorated. In the composite yarn according to the third aspect of the present invention, the multifilament and discontinuous fibers overlap each other so as to overlap the width h with a distance corresponding to a width Η of 90 to 10%, preferably 80 to 20%. Thereby, the composite yarn has a special structure in which a multifilament layer and a discontinuous fiber layer are spirally wound and it is expected that the composite yarn has good properties such as few fluff, improved weaving properties, and when monofilament and discontinuous fiber are different Improves the appearance of salt and pepper when color is dyed, and reduces small stains when the yarn is heavily dyed. If the opening width h of the multifilament of the synthetic fiber does not overlap with the opening width Η of the discontinuous fiber hair, or they are separated from each other, the structure of the composite yarn is modified so that a spiral structure cannot be formed and thus the above-mentioned effect cannot be achieved. The supply location of multifilament and discontinuous fiber hairs of synthetic fibers may have an influence on the structure of the manufactured yarn. In the case of spinning a yarn having a Z-twist, the multifilament yarn of the synthetic fiber is displaced to the right with respect to the discontinuous fiber hair. In the case of spinning yarns with S-twist, the multifilament yarns of synthetic fibers are displaced to the left relative to the discontinuous fiber hairs. Thereby, a desired yarn structure is obtained stably. In these cases, the winding direction is clockwise in the case of Z-twisting or counterclockwise in the case of S-twisting. The position of supplying the multifilament and discontinuous fibers can be adjusted by controlling the position of the fiber opening electrode, or by using a specific yarn guide for opening the monofilament. The fiber opening width of the multifilament can be controlled by controlling voltage, supplying tension, specific yarn guides for monofilament -23- (20) 200417640, and so on. The composite yarn according to the third aspect of the present invention can be manufactured using the device shown in Fig. 2 (which has been explained) while controlling the spinning conditions.

In order to manufacture continuous and discontinuous fiber composite yarns, the multifilament A is unwound from a bobbin 8 and passed through a yarn guide 9 to an 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 stretched into individual filaments. The charged multifilament passes through the yarn guide ring 7 and is then supplied to the front roller 3 while adjusting the fiber opening width and supply position. Separately, the coarse discontinuous fibers B are supplied to the rear roll 1 and then drawn between the carriage 2 and the front roll 3. Thereafter, the discontinuous fibers B are supplied to the front roller 3 in a bundle form of the discontinuous fibers B. Then, the multifilament A, which has been opened or splayed, is mixed or tangled with the bundles of wool in the form of discontinuous fibers b at the nip of the front roller 3. In this stage, the maximum fiber opening width of the discontinuous fiber hairs 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 hair, which is twisted through the front roll 3 to form a specific yarn structure such that the cross section of the yarn has a central portion of a uniformly mixed layer of monofilaments and discontinuous fibers and surrounds the center Peripheral layers of partially discontinuous fibers. Finally, the twisted yarn passes through the volute guide 4 and is then wound on a winder 10 having a loop and a traveler 5. Now, a composite yarn according to a fifth aspect of the present invention will be explained. A composite yarn according to this viewpoint is a continuous and discontinuous fiber yarn containing acrylate fibers. The acrylate fiber used in this composite fiber is a fiber of -24 · (21) (21) 200417640 acrylic acid or a cross-linked copolymer thereof with a light metal salt and acrylamide, and has temperature-control, moisture-control, Harmonious nature. However, as explained, these acrylate fibers have very weak strength and non-strength, which is about one-half to one-third of other synthetic fibers such as polyester fibers used as clothing materials. Therefore, it is necessary to mix acrylic fibers with natural fibers and / or synthetic fibers. In order to produce yarns of local quality, composite yarns must be formed from monofilaments of synthetic fibers. When a mixture of acrylate fiber and natural fiber and / or synthetic fiber is combined with a monofilament of synthetic fiber, the yarn can have high strength, and thus a yarn with a relatively small number of yarns and acrylate fiber in the composite yarn can be spun. The percentage can be increased. In order to obtain a high-quality yarn, a preferred composite configuration is such that a fiber bundle of a mixture of acrylate fiber and natural fiber and / or synthetic fiber is entangled with a monofilament of synthetic fiber. The monofilament of the synthetic fiber may be any monofilament used in clothing. In view of strength, polyester and polyamide resins are preferred. In view of yarn quality, yarns having a monofilament count of at least 5 are preferred. The percentage of monofilament in the composite yarn is preferably from 10 to 35%. When this percentage is less than 10%, the properties and quality of the yarn may not be improved. When this percentage exceeds 35%, the quality of the fiber bundle containing the acrylate fiber decreases. As a result, the mixing ratio of the acrylate fiber and the spinning count are greatly restricted. The blending percentage of the acrylic fiber is preferably from 5 to 45%, more preferably from 10 to 40%, from the viewpoint of functional properties and yarn quality. When the mixing percentage of acrylate -25- (22) 200417640 fibers is less than 10%, the three properties, namely, temperature control, moisture control, and blending properties, may not be sufficiently improved. When the mixing percentage of the acrylate fibers exceeds 40%, the yarn quality is significantly reduced, and a high percentage of the acrylate fibers is undesirable from a cost standpoint. The composite yarn according to the fifth aspect of the present invention preferably has 200 fluff / 1 000m or less, better 100 fluffs / 1 000m less concentrated fluff

In order to make a tube-quality fabric, the composite yarn preferably has a concentrated fluffing rate of 100 fluffs / 1000m or less, and in particular 70 fluffs / 1000m or less. Because if the number of fluffs is large, acrylic fibers may not be dyed, and the part of these fabrics where the fluffs are seen will be white after the fabrics are dyed. As a result, the quality of the fabric is significantly reduced. Various test results show that the concentrated fluff is composed of acrylate fibers. The generation mechanism of concentrated fluff of acrylate fiber can be assumed as follows: In the processing method, many discontinuous fiber breaks occur due to abrasion by metal and other fibers, and poor fiber stretching results in increased fiber defects and thus concentration. Fluff. Since the concentrated fluff contains the nine-shaped fluff formed in the same area, the number of concentrated fluff can be easily calculated. Specifically, the number of concentrated fluffs is calculated as follows: The yarn is wound around the gauze with a pitch of 20 yarns / inch. Manufactures four gauze wraps. Then, the number of concentrated fluffs found on the yarn was counted and converted into a number per 1000 m of yarn. Only when the yarn contains acrylate fiber, the generation of concentrated fluff is not special. -26- (23) (23) 200417640 is a very special phenomenon. This phenomenon becomes more pronounced as the percentage of acrylate fibers in the yarn increases, and yarns that do not contain acrylate fibers sometimes produce concentrated fluff. These high-quality yarns with 100 fluffs / 1,000m or less concentrated fluffs can be manufactured by compounding acrylate fibers and monofilaments. The composite configuration of the yarn is not limited, and the following configurations may be particularly advantageous. These monofilaments, which are supplied from the monofilament supply module and are opened with electrical fiber opening devices, are bundled with acrylate fibers and natural and / or synthetic fibers, which are tangled from the coarse fiber supply module, and then They are twisted to obtain high-quality yarns (with 100 fluffs / 1 000m or less concentrated fluff). The reason why a high-quality yarn is obtained may be that the concentrated fluff of the acrylate fiber is splayed or wound to a monofilament divided into individual monofilaments. In addition to the methods described above, the following methods can be used to produce composite yarns by twisting discontinuous fiber bundles (B) of acrylic fibers and natural and / or synthetic fibers and continuous fiber bundles (A) of synthetic fiber monofilaments. That is, multifilament, which is substantially in a bundled state, is wound with a fiber bundle to be stretched, and then twisted and wound, or temporarily twisted to form a yarn having a tangled fluff. Alternatively, the stretched fiber bundles are entangled with the fiber opening multifilament, and then they are twisted and wound, or temporarily twisted to form a yarn having a tangled fluff. The composite yarn according to this viewpoint can be manufactured by any of the above methods. The high-quality composite yarn according to the fifth viewpoint of the present invention can also be entangled with the monofilament and coarse fibers supplied from the monofilament supply module through the supply guide. Acrylic fiber and natural and / or synthetic fiber fiber supplied by the supply unit are -27- (24) 200417640 to form the first fiber bundle, and at the same time supply tension to the monofilament by a tension mechanism such as a tension roller, and then combine the first One fiber bundle and a second fiber bundle containing natural and / or synthetic fibers but no acrylic fibers and the first fiber bundle and the second fiber bundle are separated by a distance of 3 to 8 mm, and actually twist them .

In the above method, the first and second fiber bundles are twisted to entangle the two types of fiber bundles with each other. Therefore, disturbance of fiber orientation is suppressed, and generation of fluffing in turn is suppressed. In addition, the first fiber bundle is surrounded by a second fiber bundle that does not contain acrylate fibers. These two effects work together to make high-quality composite yarns.

Furthermore, the high-quality composite yarn according to the fifth aspect of the present invention can be entangled with the monofilament supplied from the monofilament supply module via the supply guide and the acrylic fiber supplied from the coarse fiber supply module and natural and / Or synthetic fiber fiber bundles to form fiber bundles, while supplying tension to the monofilaments with a tension mechanism such as a tension roller, and twisting the fiber bundles generated in the previous step to form a monofilament that surrounds the outside of the front roller and passes through the yarn guide roller. The fiber bundle is manufactured without supplying tension to the monofilaments. In this method, the monofilaments supplied from the outside of the front roller almost completely cover a fiber bundle containing acrylate fibers. The composite yarn according to the seventh aspect of the present invention is explained in detail. The synthetic fibers constituting the continuous fiber bundle (A) may be any conventional synthetic fibers. Examples of synthetic fibers include monofilaments of polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, and the like; polyamines such as aliphatic polyamines And aromatic polyamide (such as nylon 6, 28-28 (25) (25) 200417640 nylon 66, etc.) monofilament; polyolefins such as polyethylene, polypropylene, etc. monofilament; acrylic or acrylate Monofilament of resin; etc. Among them, such polyester fibers, particularly 'polyethylene terephthalate fibers, are preferable from the viewpoint of easy handling and cost. In addition to conventional polyesters, polyesters can include copolyesters, for example, containing acids such as isophthalic acid, adipic acid, sebacic acid, naphthalenecarboxylic acid, terephthalic acid, and the like and alcohols such as propylene glycol, succinic acid, and the like. Copolymers of alcohol, diethylene glycol, etc.

The fineness of the synthetic fiber is preferably 300 dtex or less. When the fineness exceeds 300 dtex, such fibers may not be fully opened unless a high voltage is used, and therefore manufacturing costs increase. In addition, when a synthetic fiber having such a fineness is used, the composite yarn has a large fineness. The fineness of synthetic fibers is more preferably from 10 to 150 dtex, and particularly preferably from 15 to 100 dtex. The synthetic fibers of the continuous fiber bundle (A) may be treated with an oil containing an antistatic agent. Examples of the antistatic agent include alkyl sulfonate, alkylbenzene sulfonate, alkyl sulfate, alkyl phosphate and the like. They can be used independently or as a mixture of two or more. Antistatic agents are often used to easily electrically open synthetic fibers. The amount of the antistatic agent is usually from 12 to 50% 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 fibers may not be improved so that the composite yarn has unsatisfactory quality. When the amount of the antistatic agent exceeds 50% by weight, the antistatic agent seriously smokes during stretching. The amount of the antistatic agent is preferably from 15 to 40% by weight, more preferably from 18 to 30% by weight. -29- (26) (26) 200417640 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 surface area of the fiber is reduced and therefore a small amount of oil is preferred. When the single fineness is small, the surface area of the fiber increases and therefore a large amount of oil is preferred. In this specific embodiment of the present invention, when the single fineness is from 1 to 2.5 dtex, the amount of the oil agent is preferably from 0.2 to 1.1%, more preferably from 0.3 to 0.9%, Very good from 0.4 to 0.7%. Within this range, the fibers are preferably opened or expanded. When an oil agent is applied to the synthetic fibers, the fibers can be effectively opened. In order to properly evaluate the fiber opening properties of synthetic fibers, it is preferred to use resistors at 25 ° C and 40% RH. When a synthetic fiber has a resistance of 8 × 10 8 Ω or less at 25 ° C and 40% RH, it has good fiber opening properties, even if it contains carbon black. When the resistance exceeds 8 X 108 Ω, the fiber opening becomes more uneven, so spots are easy to appear when the continuous fibers are combined with the discontinuous fibers to form a composite yarn. In order to achieve a resistance of 1 X 1 0 4 Ω, a larger amount of an oil agent, that is, an antistatic agent should be applied to synthetic fibers and the fiber opening properties are easily deteriorated. Therefore, the resistance is preferably from 1 X 1 05 Ω to 6 X 108 Ω, and more preferably from 1 X 106 Ω to 4 X 108 Ω. Specific examples of the antistatic agent include poly (oxyethylene) alkylamine, poly (oxyethylene) alkylamidamine, poly (oxyethylene) alkyl ether, poly (oxyethylene) alkylphenyl ether, Glycerin fatty acid ester, sorbitan fatty acid ester, alkyl sulfonate, alkyl benzene sulfonate, alkyl sulfate, alkyl sulfate, alkyl phosphate, quaternary ammonium chloride, quaternary sulfuric acid Ammonium, quaternary ammonium nitrate, alkyl sweet-30- (27) 200417640 carnitine, alkylimidazoline, alkylaniline, etc. They can be used independently or as a mixture of two or more. Among them, anionic antistatic agents such as alkylsulfonate, alkylbenzenesulfonate, alkylsulfate, alkylphosphate 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 an oil component, 5 to 30 parts by weight of an emulsifier, and 12 to 50 parts by weight of an 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 parts in contact with the fiber becomes too large and may be the cause of the generation of fluff. When the amount of the emulsifier is less than 5 parts by weight, when the oil agent 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 an oil component, 10 to 20 parts by weight of an emulsifier, and 18 to .30 parts by weight of an antistatic agent. As a 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 may be used. Emulsifiers may also be conventional emulsifiers, and examples thereof include glycerin fatty acid esters, sucrose fatty acid esters, sorbitan fatty acid esters, and propylene glycol fatty acid esters. , POE ether-addition product oil, PEG ester-addition product oil, lecithin and the like. They can be used in their mixtures. Among them, PEG dioleate, fatty alcohols and their metal salts are particularly preferred. The synthetic fibers used in this embodiment preferably include fine particles. These fine particles can reduce the smoothness or slipperiness of the fiber surface, but the use of an oil agent to optimize the coefficient of friction and improve the fiber opening properties is -31-(28) (28) 200417640. The fine particles may be any fine particles usually mixed in fibers such as pigments, matting agents, antibacterial agents, antistatic agents, and the like. Carbon black-colored fine particles are preferred, because fibers containing these fine particles have good fiber opening properties, so the speckles caused by fiber mixing are suppressed and the stains are reduced. The fibers may contain additives such as matting agents, antibacterial and antistatic agents other than those exemplified above, and other polymers. In addition to carbon black, the pigment may be any pigment having other colors. In order to add these fine particles to the fiber, in the case of carbon black, a dense body containing 5 to 40% by weight of carbon black and a synthetic resin and a matrix polymer without a synthetic resin containing carbon black are mixed and melted Spinning to obtain dope black dyed polyester fibers. 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 mixed well with the polymer, so unevenness becomes attractive. Eye-catching. The dense body and the matrix polymer can be mixed by any conventional method. For example, 'colored body particles and matrix polymer particles are mixed before melting and then the mixture is melted. Alternatively, the dense body particles and the matrix polymer particles are melted separately, and then the melt is statically mixed with a static mixer just before the filament. After mixing, the mixture is processed by conventional melt spinning methods to obtain fibers. The cross section of each fiber can have any shape such as round, deformed (side) shape, hollow shape, etc. The carbon black used in the present invention may be channel black, furnace black, or the like. When the carbon-32- (29) 200417640 black main particle size is too small, when the carbon black particles are mixed in a polyester such as a polyethylene terephthalate type copolyester, they tend to aggregate and the mixture is spun. It can be difficult. When the size of the main carbon black particles is too large, the depth of black decreases. Therefore, the main particle size of carbon black is preferably from 10 to 40 nm. When the main particle size is less than 10 nm, the handling of carbon black is difficult. When the primary particle size exceeds 40 nm, the back pressure in the nozzle increases during spinning, resulting in deterioration of operability due to yarn breakage and the like.

Discontinuous fiber bundles (B) containing natural fibers and / or synthetic fibers, which are supplied from a crude fiber supply module, preferably including wool, cotton, silk, hemp, linen, ramie, synthetic fiber cut fibers, rayon staple fibers, The acetate cuts the fiber and its mixture. Among them, wool is better.

The composite yarn according to the seventh aspect of the present invention preferably has a raising rate of 1,000 fluffs / 10m or less, for a fluff having a length of at least 1 mm. In order to manufacture a high-quality fabric, the raising rate is preferably 700 raisings / 10 m or less. When the number of fluffs is large, portions of these fabrics where the fluff is concentrated are seen white after the fabric is dyed, and thus the quality of the fabric is significantly reduced. The composite yarn according to the seventh aspect of the present invention can be manufactured as follows: Substantially in a bundled state, entangled with the fiber bundle to be stretched, and then twisted and wound, or temporarily twisted to form a yarn with entangled fluff ° or, the stretched fiber bundle is opened with the fiber opening multifilament Twist, then stomach them twist and roll, or temporarily twist to form a yarn with lingering fluff. Furthermore, the high-quality composite yarn according to the seventh aspect of the present invention can be borrowed by -33- (30) 200417640. Fiber bundles of natural and / or synthetic fibers are entangled with the monofilament (A) fiber bundles supplied from the monofilament supply unit via the supply guide to form a fiber bundle, while supplying tension to the monofilaments by a tension mechanism such as a tension roller, and twisting The fiber bundles produced in the foregoing steps are manufactured by simultaneously twisting the fiber bundles (B) passing from the outside of the front roller through the guide roller without supplying tension to the monofilaments. In this method, the monofilaments supplied from the outside of the front roller completely cover the fiber bundle (B).

In addition to the methods described above, composite yarns can be made by continuously opening synthetic fiber monofilaments (A). In order to charge the synthetic fiber monofilament (A) and continuously open the monofilament, an oblique-shaped electrode as disclosed in JP-A-47- 1 1 247 can be used. In addition to using fiber opening electrodes, fibers can be corona-discharged, ionized air media, or opened or splayed by contacting the fibers with high-voltage electrodes. These continuous synthetic fibers (A) are supplied from a monofilament supply module and are opened using an electrical fiber opening device, and fiber bundles (B) of natural and / or synthetic fibers are supplied from a crude fiber supply module, wrapped Knot, and then twist them to obtain high-quality yarns (with 700 fluff / 1000 m or less fluff). The positions of the continuous synthetic fibers (A) and the discontinuous fiber bundles (B) supplied can be adjusted by controlling the position of the fiber opening electrode, or by using a special yarn guide using an opening monofilament. The fiber opening width of continuous synthetic fiber (A) can be adjusted by controlling the voltage, the strength of the supply, the special yarn guide of the monofilament, etc. The continuous and discontinuous fiber composite yarns of the present invention can be manufactured using the apparatus shown in FIG. 2. -34- (31) 200417640 In order to manufacture continuous and discontinuous fiber composite yarns, the multifilament A is unwound from a rafter 8 and passed through a yarn guide 9 to an 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 stretched into individual filaments. The charged multifilament passes through the yarn guide ring 7 and is then supplied to the front roller 3 while adjusting the fiber opening width and supply position.

Separately, the coarse discontinuous fiber B is supplied to the rear roll 1 and then stretched between the carriage 2 and the regular roll 3. Thereafter, the discontinuous fibers B are supplied to the front roller 3 in a bundle form of the discontinuous fibers B. Then, the multifilament A, which has been opened or splayed, is mixed or tangled with the bundles of wool in the form of discontinuous fibers b at the nip of the front roller 3. In this stage, the center of the multifilament A is substantially aligned with the center of the width of the discontinuous fiber hairs while limiting the opening width of the fibers of the multifilament to 50 to 300% of the maximum width of the discontinuous fiber hairs. The mixture of the multifilament A and the discontinuous fiber hairs is twisted by the front roller 3 to form a yarn structure having a cross section composed of a uniformly mixed layer of monofilaments and discontinuous fibers. Finally, the twisted yarn passes through a volute guide 4 and is then wound on a winder 10 having a loop and a traveler 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 little fluff and a uniform salt and pepper appearance of different colors when the synthetic fibers (A) are dope-dyed fibers. In addition, because the number of fluff is small, the yarn has improved weaving properties. Composite yarns can be processed into plain weave, twill, satin, etc. -35- (32) 200417640 form 'or knit, for example, warp knit and weft knit. These fabrics have good deep-dyeing properties, no small spots of dyeing, and also improve texture 'and are particularly suitable for sewing black dresses. In the synthetic fiber according to the eighth aspect of the present invention, contains! 2 to 50% by weight of antistatic agent based on the total weight of the fiber! ·;!% Or less adheres to the fiber, and the fiber has a resistance of 8 X 1 08 Q or less at 25 ° C and 40% RH.

The synthetic fibers used in connection with the above specific embodiments represent conventional synthetic fibers, and examples of the synthetic fibers are the same as those related to the continuous synthetic fibers (A) of the composite yarn according to the seventh aspect of the present invention. The oil agent containing the antistatic agent, and the amount and resistance of the oil agent to be used in this embodiment are the same as those explained for the composite yarn according to the seventh aspect of the present invention. The synthetic fibers used in this embodiment preferably contain fine particles. These fine particles can improve the smoothness or smoothness of the fiber surface, but the use of an oil agent optimizes the coefficient of friction and improves the fiber opening properties. The fine particles may be any fine particles usually mixed in fibers such as pigments, matting agents, antibacterial agents, antistatic agents, and the like. Carbon black-colored fine particles are preferred. Because fibers containing these fine particles have good fiber opening properties, the spots caused by fiber mixing are suppressed and the stains are reduced. The fibers may contain additives such as matting agents other than those exemplified above, antibacterial and antistatic agents, and other polymers. In addition to carbon black, the pigment may be any pigment having other colors. In order to add these fine particles to the fiber, in the case of carbon black, -36- (33) 200417640 contains 5 to 40% by weight of carbon black and a dense color body of synthetic resin, and synthesis without carbon black The resin matrix polymer is mixed and melt-spun to obtain a dope 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 mixed well with the polymer, so unevenness becomes attractive. Eye-catching.

The dense body and the matrix polymer can be mixed by any conventional method. For example, dense body particles and matrix polymer particles are mixed before melting, and then the mixture is melted. Alternatively, the dense body particles and the matrix polymer particles are melted separately, and then the melt is statically mixed with a static mixer just before the filament. After mixing, the mixture is processed by conventional melt spinning methods to obtain fibers. The cross section of each fiber can have any shape such as round, deformed (side) shape, hollow shape, etc. The carbon black used in the present invention may be any conventionally used carbon black. These types and particle sizes have been explained. The fineness of the synthetic fiber may be the same as that of the synthetic fiber according to the seventh aspect of the present invention. Now, the electric fiber opening device according to the present invention will be explained by referring to the drawings. ≪ A specific embodiment of the fiber opening device > Fig. 3 schematically shows a cross section of the first embodiment of the electrical fiber opening device according to the present invention. -37- (34) 200417640 The fiber opening device 1 includes a main body 2 made of an insulating material, which is provided in a fiber running direction and has a specific length in that 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 made of an insulating material and provided on the rear side with respect to the yarn running direction. The cover member 5 has an opening through which a 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 yarn running direction. The ring 6 is provided so 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 6 A of the grounding ring is larger than the outer diameter of the yarn outlet 3 B 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 installed along a vertical line, so the multifilament is conveyed downward and is opened or opened stably, that is, the cover member 5 faces upward and the ground ring 6 faces downward. However, the fiber opening device 1 can be installed in any direction other than the vertical direction. The electrode 3 for supplying a voltage has a hollow cylindrical shape, so that the multifilament can pass through the electrode. The shape of the cross section 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 hinder the running of the yarn. In order to maintain the 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, and the inner diameter of the electrode 3 is usually From 0.3 to 6 mm, preferably from 0.5 to 3 mm, and more preferably from 0.8 to 2 mm. -38- (35) 200417640 The fiber opening device 1 is used. Voltage is supplied from the power source 4 to the electrode 3 and the multifilament is 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, and the like, and other conductive materials such as conductive plastic 'include plastic or ceramic mixed with metal powder and the like.

The ground ring 6 provides a downflow in the electrode 3 with respect to the running direction of the yarn. The ring 6 is connected to the ground and has a substantially zero potential. Since the multifilament is charged through the electrode 3 and then passes through the grounding ring 6, the charging filament of the multifilament is attracted by the grounding ring 5. This can help open the fiber. The material of the ground ring 6 is not limited 'as long as it attracts such charging monofilaments. Examples of the material of the ring 6 include conductive metals such as iron, copper, silver, and the like, and other conductive materials such as conductive plastic, including plastic or ceramics mixed with metal powder and the like.

In order to help the opening of the multifilament fibers, the shape of the internal space of the grounding ring 6 is preferably such that the front end of the space exists downstream of the space ′ is larger than the rear end of the space exists upstream of the space. 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 multifilament can be evenly opened or opened in all cross-sectional directions. In order to loosen the multifilament stably, the inner diameter of the front end 6 B 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. The distance between the front end 6 B and the rear end 6 A is usually from 3 to 25 mm, preferably from 5 to 20 mm, more preferably from 7 to 15 m m 〇 -39- (36) 200417640

The yarn exit 3 B of the electrode exists between a position of 6 A from the rear end of the ground ring and 5 mm in the reverse direction with respect to the yarn conveyance, and a position of 23 mm from the rear end of the ground ring 6A with respect to the yarn conveyance direction. Preferably, the yarn exit 3B of the electrode exists between a position of 6 mm away from the rear end of the ground ring 6A with respect to the yarn conveyance and a position of 20 mm away from the rear end of the ground ring 6A with respect to the yarn conveyance direction. More preferably, the yarn exit 3 B of the electrode is located at a position 0 to 18 mm from the rear end of the ground ring 6A with respect to the yarn conveying direction. In any case, the yarn entrance 3 A of the electrode exists upstream of the ground ring 6 A in the direction of the yarn running, and the yarn exit electrode 3 B exists above the ground ring front 6 B of the yarn in the direction of the yarn running. . Preferably, the electrode 3 of the fiber opening device 1 is surrounded by a main body 2 made of an insulating material, and a cover member 5 (which is also made of an insulating material) having a yarn introduction opening and provided in a hollow passing through the electrode with respect to the yarn Back side of the electrode 3 in the direction of the channel. Thereby, the worker does not touch the electrode 3 and thus the safety is improved. In the fiber opening device 1, the main body 2 and the cover member 5 may not be necessary elements. The voltage supplied to the electrode 3 may be positive or negative. The absolute voltage of the voltage supplied to the electrode 3 is usually from 1 to 20 kV, preferably from 1 to 10 kv, more preferably from 2 to 7 kV. The running speed of the multifilament through the electrode is usually from 0.03 to 0.70 m / see, preferably from 0.05 to 0.55 m / sec, and more preferably from 0.07 to 0.45 m / see. In this regard, the rotation rate of the multifilament winding spindle is usually from 3000 to 15,000 rpm, preferably from 4000 to 1 3,000 rpm, and more preferably from 5000 to 1 1,000 rpm . The tension applied to the multifilament is 10 gf (gram-force) or less -40- (37) 200417640, preferably 5 gf or less, more preferably 2 gf or less. Multifilament is a continuous fiber comprising synthetic fibers, which has been described in relation to composite yarns according to the invention. < Second specific embodiment of the fiber opening device > When the fiber opening device of the first embodiment is used, the multifilament can be completely opened or opened and opened monofilament

Constant contact with the yarn exit of the electrode causes the electrode to tend to be worn. When a rigid tube having an inner diameter at 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 opened monofilaments do not directly contact the electrode and thus prevent the electrode from abrasion. In principle, the hard tube is connected to the electrode so that the hard element is at least in contact with the front end of the yarn outlet of the electrode to prevent the opened monofilament from directly contacting the yarn outlet of the electrode. The hard tube is usually a hollow circle with a yarn inlet and yarn outlet of the same inner diameter cylinder. However, the inner diameter of the yarn inlet and outlet 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 an implementation of the second specific embodiment of the fiber opening device, the yarn outlet of the electrode is connected to or inserted into the yarn inlet of the hard tube, so the yarn outlet of the hard tube is supported above the electrode outlet in the running direction of the yarn. Fig. 4 shows an enlarged cross-sectional view of the voltage supply electrode 3 and the rigid tube 7 of the fiber opening device close to the yarn outlet of this embodiment. The distance between the yarn outlet 3 B of the electrode connected to or inserted into the hard tube 7 and the yarn outlet 7 B of the hard tube 7 is usually 10 mm or less, preferably 7 mm or less, more -41-( 38) (38) 200417640 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 pipe is made of a hard material such as ceramic or stainless steel, or a material having a hard-layer-coated inner surface such as diamond or sanded carbide. A larger part of the electrode 3 is inserted in a hard tube to protect the electrode 3. In this case, the 'electrode is inserted into the hard tube at a distance from the external power supply voltage to the electrode. 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 into the hard tube 7 to leave an exposed portion connected to the power source. Alternatively, a window is formed in the middle portion of the hard tube 7 and the electrode 3 is connected to the power source through the window. In order to prevent the electrode from being worn by the opened monofilament of the multifilament, at least the inner surface of the exit area of the electrode 3 may be made of hard material instead of using a hard tube. For example, the inner surface of the electrode is coated with a hard layer, such as diamond or silicon carbide.
