Description

COMPOSITE YARN OF LONG AND SHORT FIBERS, METHOD FOR PRODUCING THE SAME, CLOTH OR FABRIC COMPRISING THE SAME AND FIBER-OPENING APPARATUS FOR PRODUCING COMPOSITE YARN}

The present invention entangles (or mixes) the stretched discontinuous fiber bundles and the opened (or divided into individual filaments or spreads) synthetic fiber multifilament yarns, winding them substantially while twisting them. A novel composite yarn comprising continuous fibers and discontinuous fibers manufactured by (wind-up), a method of manufacturing the composite yarn, a cloth or fabric comprising the composite yarn, and a carding machine for manufacturing the composite yarn will be.

Until now, the following method has been known as a method of combining a discontinuous fiber bundle and a multifilament yarn:

(1) yarns that wrap substantially filamentary filament yarn into stretched discontinuous fiber bundles and twist and wind them (1-1), or temporarily twist and bundle them to wrap fine hair (Iii) forming (1-2);

(2) Wrap the stretched fiber bundles with opened multifilament yarns and twist and wind them up (2-1), or temporarily twist and bundle them to form yarns with fine hairs (2-2).

However, the method (1-1) has the disadvantage that a greater number of twists must be applied than conventional yarns made of staples in order to improve the entanglement of the bundle of stretched discontinuous fibers and multifilament yarns. Method (1-2) has the disadvantage that discontinuous fibers and multifilaments must be glued, fused or moderately twisted because they are insufficiently intertwined with only temporary twisting or bundling.

Method (2-1) has the disadvantage that the twisted and wound yarns have a sticky or shiny appearance, although they have uniformity. In the method (2-2), the multifilament yarns are excessively opened or stretched so that the staples do not function sufficiently as to wrap fine hair, which is not uniform when there are many longitudinal bundling states.

A method has been proposed that involves intertwining a fiber bundle with a bulk thread (for example JP-A-49-101639). However, this method has a poor appearance in which nep and spots are easily formed because fiber bundles must be made in an overfeeding state and a high speed vortex jet is used.

Moreover, a composite yarn comprising a filament component and a discontinuous fiber component has been proposed, but in a twisted state, the filament component is present in the core portion, and the discontinuous fiber portion is present in the sheath portion (for example, JP-A- 59-30925 and JP-A-61-239036). However, this composite yarn has an inadequate pepper-and-marble appearance when dyed in other colors, has a large skitteriness in deep dyeing, and when weaved It causes a lot of problems.

Among synthetic fibers, acrylic fibers are attractive because they have excellent functions (temperature control, humidity reduction, harmonization). In order to take advantage of such features, mixed yarns of acrylic fibers and other materials are used in sports and in the field. However, acrylic fibers only have a tenacity of 0.55 to 1.82 g / d and nodular strength of 0.3 to 1.5 d / g. Thus, when the acrylic fiber is mixed and spun with other materials, there is a problem of trimming of the discontinuous fiber and dropping of the fiber. This disadvantage of acrylic fibers is noticeable when the proportion of acrylic fibers in the blended yarn is increased.

If the proportion of acrylic fibers in the blended yarns is reduced, the problem can be overcome, but the characteristics as functional fibers are greatly impaired, which is a fatal problem. Therefore, conventional mixed yarns containing acrylic fibers have problems in terms of yarn properties and yarn quality. In particular, the strength of the yarn is greatly reduced due to the properties of the acrylic fiber and damage to the acrylic fiber during processing. Therefore, the content of acrylic fiber in the blended yarn is greatly limited. Also, the number count is limited to a large number.

With regard to yarn quality, the trimming of discontinuous fibers occurring during acrylate fiber processing increases the number of naps produced in the spun yarn and also increases the number of areas where the nap is concentrated in the longitudinal direction of the yarn. Therefore, yarn quality is greatly reduced. When a fabric containing such yarns is dyed, the area where the nap is concentrated appears white and the quality of the fabric is also greatly reduced. Thus, blended yarns comprising acrylic fibers are used for applications that do not require the back of the fabric or very high quality fabrics.

In consideration of the properties of the acrylate fibers, it has often been attempted to cut the acrylate fibers into short lengths and to use the fibers cut by a method such as coating when dyeing. This method is excellent in terms of functional application, but the use of acrylates by coating or the like makes the texture of the fabric stiff and the thickness of the fabric increases. Thus, the inherent texture of the fabric is damaged. Thus, this method can be used for limited applications.

Nowadays, there is a great need for high quality sport-in-the-text fabrics utilizing the high functionality of acrylate fibers. However, as described above, it is difficult to impart high functionality of acrylate to the fabric by increasing the proportion of acrylate fibers in the blended yarn. Thus, no composite yarn comprising acrylate fibers was provided.

In order to produce composite yarns, electric fiber carding methods are known (for example, JP-A-54-17063 and US Pat. No. 3,657,871). Composite yarns and double-layer yarns comprising fiber bundles and single filaments are also known (eg JP-A-6-228838 and JP-A-2000-17532). However, these patent publications do not disclose composite yarns comprising acrylate fibers.

Composite yarns of continuous and discontinuous fibers are supplied in the form of mixed yarns of various fibers, and are produced by various composite methods in various forms. However, composite yarns of continuous fibers and discontinuous fibers, including fibers dope dyeed to enhance texture or color tone, are not known. When using dope dyed fibers, the fibers may be uneven due to the less uniform mixing encountered during the manufacture of the dope dyed fibers, or reeds or needles may be removed by fine particles of the original colorant during processing such as weaving. Worn out.

As dope dyed yarns, those made of synthetic fibers such as polyester, polyamide and the like are known, which contain mixed colored particles such as pigments. However, it is not known to open such yarns. In particular, black polyester fibers produced by dope dyeing (hereafter referred to herein as " dope black-dyed fibers ") may be added to the polyester at any stage during the polymerization process or up to fiber formation after polymerization. (For example, JP-A-8-13248). However, when producing composite yarns by opening such dope black-dyed fibers, it is difficult to uniformly open the fibers (for example, JP-B-4-78749 and JP-B-54-17063), Composite yarns have a bold color spot and cannot be used to weave fabrics that can be used in dress suits (or robes). When the fibers are not uniformly opened, the color spot is more pronounced in the fabric comprising such fibers.

As described above, when producing a composite yarn, an apparatus for electrically opening or extending fibers is known as an apparatus for opening multifilament yarns. For example, JP-UM-50-9366 A is a device for electrically charging yarns and opening or extending fibers by passing a multifilament yarn through a hollow cylindrical electrode for voltage application followed by a ground ring. JP-UM-50-35149 A discloses an apparatus for spraying a pressurized liquid onto a filament yarn, and then passing the yarn through a hollow cylindrical electrode for voltage application and then through a ground ring to electrically charge the yarn and open the fibers. To start.

The degree of fineness of the multifilament yarns by such an electric weaving device depends on the tension applied to the yarns, environmental conditions (for example, temperature, humidity, etc.), types of multifilaments, and the like. For example, as the traveling spped of the multifilament yarn increases, the charging amount of the multifilament yarn decreases, and the tension on the yarn increases. Thus, the openness decreases. Therefore, the strength of the applied voltage, the moving speed of the yarn and the tension applied to the yarn must be determined based on the operator's experience and preliminary experiments in order to obtain a stable degree of opening independent of changes in the manufacturing conditions.

Therefore, in order to improve productivity efficiency, the electric carding machine which can obtain stable opening degree despite the change of manufacturing conditions has been calculated | required.

Such a carding machine passes a multifilament yarn through a hollow tube electrode for voltage application, thereby charging the yarn and connecting the yarn. Therefore, when the fiber of the multifilament yarn is completely opened, the opened fiber continuously touches the fiber outlet of the electrode, and the fiber outlet tends to wear out. That is, when the multifilament yarn is fully opened, worn electrodes must be replaced frequently, which causes a problem of a decrease in manufacturing efficiency due to interrupting manufacturing for electrode replacement.

Therefore, there is a need for an electrical carding machine capable of preventing wear of an electrode for applying a voltage to the multifilament yarn while maintaining a sufficient degree of fineness of the multifilament yarn.

It is a first object of the present invention to utilize the superior hand of discontinuous fibers and the eveness and high strength of continuous fibers, to improve the weaving performance, and to produce lightweight, diaphanous woven fabrics.

It is to provide a composite yarn of continuous and discontinuous fibers and a method for producing such yarn.

A third object of the present invention is to show the high functionality of acrylate fibers, in particular to prevent deterioration of inherent properties, strength and nodular strength, damage of acrylate fibers caused by mixing with other materials, trimming of discontinuous fibers and It is to provide a yarn suitable for high-quality fabrics having high performance (temperature control, humidity control, conditioning) with a suppression of dropping of fibers.

Detailed description of the invention

First, the continuous and discontinuous fiber composite yarn according to the first aspect of the present invention and a manufacturing method of the composite yarn will be described with reference to the drawings. The drawings are used to illustrate the invention and are not intended to limit the scope of the invention.

The continuous and discontinuous fiber composite yarns of the present invention include synthetic fiber multifilaments and discontinuous fibers that are opened and mixed. 1A shows a cross-sectional structure of a composite yarn, where the central portion comprises a uniform mixture of filaments and discontinuous fibers of synthetic fibers, and the periphery includes discrete fibers surrounding the central portion.

Composite yarns having such a structure provide a lighter and less shiny fabric when the yarn is woven or knitted, and the fabric comprising such yarn has a deep salt property and less skinnyness when made of black dress suits.

Preferred examples of the synthetic fibers of the multifilament constituting the composite yarn include polyester fibers, polytrimethylene terephthalate fibers, polyamide fibers, polyolefin fibers, polyacrylonitrile fibers, polybutylene terephthalate fibers and mixtures thereof. . Among them, polyester fibers are most preferred.

Preferred examples of the discontinuous fibers constituting the composite yarn are wool, cotton, silk, hemp, flax, ramie, synthetic fiber staples, rayon staples, acetate staples and mixtures thereof. Among them, wool is most preferred.

The multifilaments of synthetic and discontinuous fibers are opened and blended to increase the entanglement of the multifilaments and discontinuous fibers, which in turn improves the finishing properties of the yarns. Mixing means that the multifilament and the discontinuous fibers are present in a mixed state. In particular, the multifilament and discontinuous fibers are uniformly mixed in the center of the yarn so that the entanglement of the multifilament and discontinuous fibers is increased at the center. Thus, the yarn has excellent weaving properties. At the same time, the discontinuous fiber layer has a bulged structure that surrounds the uniform layer in the center, and the fabric made of such yarns is lightweight, less shiny and has a woolly feel.

Preferably, the multifilament of the synthetic fibers has a fineness of 11 to 110 decitex. If the composite yarn does not have a thickness within a certain area, it is not accepted on the market.

When the fineness of the multifilament is less than 11 decitex, the effect of the composite yarn may not be maintained. When the fineness of the multifilament exceeds 110 decitex, the texture of the fabric made of the yarn may be lost. This range of fineness is required for the production of marketable fabrics with a woolly feel.

In order to impart a woolly texture to the fabric, it is preferred that each filament has a fineness of 0.1 to 6.6 decitex, more preferably 0.2 to 3.3 decitex. When the fineness of each filament is less than 0.1 decitex, the fabric may lose stardiness. When the fineness of each filament exceeds 6.6, the feel of the fabric may deviate from the feel of all.

When staple fibers other than natural fibers are used as discontinuous fibers, they may be cut to the same length or to unequal lengths. The average length of the staple fibers is preferably 50 to 150 mm for fabrics having a warm warmth or 25 to 50 mm for fabrics having a warmth of cotton.

In the composite yarn, the amount of discontinuous fibers is preferably 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 enclose a layer of discontinuous fibers and a uniform mixture of discontinuous fibers with the layer of discontinuous fibers. When the amount of discontinuous fibers exceeds 95% by weight, the entanglement of the multifilament and the discontinuous fibers may worsen.

The composite yarn according to the first aspect of the invention preferably has a fine hair index of 300 to 900 fluff / 10 m for fine hair having a length of at least 1 mm. More preferably, it has a fine hair index of 80 to 200 fluff / 10 m for fine hair having a length of at least 3 mm in addition to the fine hair index. When the fine hair index is in the above range, the fabric made from the composite yarn is lightweight, less shiny, and has a woolly feel. Here, the fine hair index is measured with an F-index tester manufactured by Shikibo Limited.

When observing the cross section of the composite yarn, the central portion comprises a homogeneous mixture of multifilament and discontinuous fibers of synthetic fibers and the periphery comprises discrete fibers surrounding the central portion. Such a structure is a feature of the composite yarn of the first aspect of the invention.

The composite yarn of the first aspect can provide a lighter, less shiny fabric with good entanglement and bristles of filaments and discontinuous fibers. Moreover, when composite yarns are used in the production of fabrics for black dress suits, the fabrics have a deep salt performance and low skininess. Thus, the fabric is suitable for manufacturing men's suits, dress suits, high quality women's dresses or blouses.

The lightweight fabric of the present invention employs the continuous and discontinuous fiber yarns described above as weft and / or warp yarns, and the average count factor of warp and weft yarns is 35 to 47, preferably 38 to flat yarns. 45, and in the case of twill we can adjust to 45 to 50, preferably 48 to 57.

Herein, plain fabric refers to all fabrics woven in a plain weave structure, which is one of three basic weaves, and includes modified plain weaves such as rib weave, mat weave, and the like.

Twill weave refers to any fabric woven in a twill structure, one of three basic weaving techniques, and includes deformed twill such as a deep twill, a diagonal twill, and the like.

For plain fabrics, the average count factor is less than 35, and the fabric has a large diaphanousness and can lose substantial properties. When the average number factor exceeds 47, the fabric may not have sufficient air permeability.

In the case of twill, when the average count factor is less than 45, the fabric may lose substantial properties. When the average number exceeds 60, the fabric may not have sufficient air permeability.

The average count is calculated as follows:

The number factor T of the slope is calculated by the following equation:

T = (number of slopes / 10 cm) / (number) ^½

The number factor W of the weft is calculated by the formula:

W = (number of wefts / 10 cm) / (number) ^½

And, the average count factor is calculated by the following equation:

Mean Count Factor = (T + W) / 2

The air permeability of the lightweight fabric of the present invention is preferably at least 50 cc / cm ² / sec, more preferably at least 90 cc / cm ² / sec.

When the air permeability is less than 50 cc / cm ² / sec, the fabric may lose its ventilation-heat radiating properties and may not provide a cool or refreshing feel.

Breathability can be measured with a Furazal type tester.

The composite yarn having a unique cross-sectional structure of the present invention can be produced as follows:

The synthetic fiber multifilament yarns are electrically opened or stretched into individual multifilaments. The stretched multifilament is then mixed or entangled with discontinuous fibers drafted just before the front roll. At this point, the center of the stretched multifilament is aligned with the center of the discontinuous fiber fleece. In addition, some of the multifilament and discontinuous fibers are collected at the center of the composite yarn, and the remainder of the discontinuous fibers is adjusted to adjust the feed tension or opening voltage, or use special guides to reduce the opening width of the multifilament yarn.

In the manufacturing method of the composite yarn according to the present invention, the opening width of the multifilament yarn should not exceed the maximum width of the discontinuous fiber fleece when they are mixed or entangled in front of the front roll.

When the opening width of the multifilament yarn exceeds the maximum width of the discontinuous fiber fleece, it is not possible to obtain a yarn structure in which the discontinuous fibers surround the uniformly joined layer of filaments and the discontinuous fibers. Thus, the effect of fine hair caused by filaments is increased, making it possible to produce less light fabrics.

The opening width of the synthetic fiber multifilament is typically equal to or less than the maximum width of the discontinuous fiber fleece, preferably 10 to 60% of the maximum width of the discontinuous fiber fleece. Thus, a uniform mixed layer of filament and discontinuous fibers constitutes the center of the composite fiber, with the remainder of the discontinuous fiber surrounding the center. Thus, it is possible to maintain the fabric's special structure and effect, for example, fabrics with improved weaving performance, light weight and less glare, heart dyeing performance and reduced skinnyness.

When the opening width of the multifilament of the synthetic fiber is less than 10% of the maximum width of the discontinuous fiber fleece, the opening effect is impaired, the weaving performance is reduced to the core yarn level, and the above effects of the present invention may not be obtained.

The position for feeding the multifilament and the discontinuous fibers can be adjusted by adjusting the position of the opening electrode or by using special guides for the opened filament. The opening width of the multifilament can be adjusted by adjusting the voltage, supply tension, special guide for the filament, and the like.

Continuous and discontinuous fiber composite yarns of the present invention can be made using the apparatus shown schematically in FIG. 2.

With reference to FIG. 2, the apparatus comprises a rear roll 1, a cradle 2 and a front roll 3, which are assembled in the above order. Beneath the front roll 3 is a winder 10 equipped with a snail wire 4 and a ring and a traveler 5. On the front roll 3, the opening electrode 6 and the guide ring 7 are provided in the above order from above.

To produce continuous and discontinuous composite yarns, the multifilament yarn A is unwound from the pir 8 and fed to the electrode 6 through the guide 9. The electrode 6 is a hollow electrode that charges static electricity to the multifilament yarn A passing through the electrode 6 to connect the yarn into individual filaments. The charged multifilament yarns pass through the guide ring 7 and are then fed to the front roll 3 while adjusting the opening width and feeding position.

Separately, crude discontinuous fibers B are fed to the rear roll 1 and then drafted in the form of a fleece-shaped bundle of discontinuous fibers B between the cradle 2 and the front roll 3. .

The fleece-shaped bundles of the opened or extended multifilament yarns (A) and discontinuous fibers (B) are then mixed or entangled at the nip point of the front roll 3. In this step, while the center of the multifilament yarn A is substantially aligned with the center of the discontinuous fiber fleece, the opening width of the multifilament yarn A is preferably adjusted to 10 to 60% of the maximum width of the discontinuous fiber fleece.

The mixture of multifilament yarns (A) and discontinuous fiber fleece passing through the front roll (3) forms a special yarn structure with the cross section of the yarn having a central portion of the mixed layer of filaments and discontinuous fibers and a peripheral layer of discontinuous fibers surrounding the central portion thereof. Braid to

Eventually, the twisted yarn passes through the snail wire 4, which is then wound around the winding machine 10 with a loop and a traveler 5.

Next, the continuous and discontinuous composite yarn according to the third aspect of the present invention and the manufacturing method of such composite yarn will be described.

These continuous and discontinuous fiber composite yarns comprise continuous filaments and discontinuous fibers of synthetic and blended synthetic fibers, the composite yarns being spirally wound around the filament layer and the discontinuous fiber layer, and in each spiral layer a multifilament layer is outward, The discontinuous fiber layer has a structure as shown in FIG. 1B, which is present inside.

Composite yarns having such a structure can provide a woven or knitted fabric with a woolly feel and an improved pepper-and-salt appearance when the filaments and discontinuous fibers are dyed in different colors, the fabric comprising such yarns being a black dress When used in the manufacture of suits, it has a deep salt performance and low skinnyness, also contains little fine hair, and has good aeration. Thus, fabrics made from this composite yarn are suitable for the manufacture of new suits, dress suits, high-grade women's dresses or blouses.

Synthetic fibers and discontinuous fibers of multifilament yarns may be the same as those used in the production of the composite yarn according to the first aspect of the invention.

Regarding the fineness of the multifilament and the fineness of each filament, the description described regarding the composite yarn according to the first aspect of the present invention may be 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 discontinuous fibers is preferably 35 to 95% by weight based on the total weight of the fibers. When the amount of discontinuous fibers is less than 35% by weight, the discontinuous fibers and multifilaments 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 with little spots.

The composite yarn according to the third aspect of the present invention preferably has a fine hair index of 200 to 900 fluff / 10 m for fine hair having a length of at least 1 mm. More preferably, the fine hair index has a fine hair index of less than 30 fluff / 10 m for fine hair having a length of at least 5 mm in addition to the fine hair index. When the fine hair index is in the above range, the fabric made from the composite yarn has a further improved quality by suppressing the formation of nep during the weaving process and improved post-processing performance such as weaving properties while maintaining a woolly feel. In addition, the fine hair index is measured with an F-index tester manufactured by Shibobo Limited.

A feature of the composite yarn according to the third aspect of the present invention is that the multifilament and the discontinuous fibers are spiral wound. The direction of the helix may be clockwise or counterclockwise. The direction of the helix can be controlled by the entangled position 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 produce the same fabric as that produced from the composite yarn according to the first aspect of the present invention, and all descriptions of the fabric made from the composite yarn according to the first aspect of the present invention. This can be applied to the fabric produced 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 produced by electrically opening the multifilament yarn of the synthetic fiber and intertwining discontinuous fibers drafted just in front of the front roll, where the maximum fleece width H of the fleece of the discontinuous yarn at the entangled point is obtained. And the maximum opening width h of the multifilament yarn continuous fiber has a relationship in which the multifilament and the discontinuous fibers are entangled so that the distance from the end point of the width H to the end point of the width h moves 10 to 90% of the maximum value of the width H.

In the above production method, when the multifilament of the opened synthetic fiber and the discontinuous fibers to be drafted are entangled in front of the front roll, it is important to move the supply axis of the multifilament of the synthetic fiber and the supply axis of the discontinuous fiber.

The maximum opening width h of the synthetic fiber multifilament yarn is preferably equal to or greater than the maximum opening width H of the fleece of discontinuous fibers. If the maximum opening width h is smaller than the maximum opening width H, the effect of laying down the fuzz with the filament is reduced and thus the weaving performance and then the quality of the fabric are poor.

In the composite yarn according to the third aspect of the present invention, the multifilament and discontinuous fibers overlap each other such that 90 to 10%, preferably 80 to 20% of the width H overlaps the width h.

Thus, the composite yarn has an unusual structure in which the multifilament layer and the discontinuous fiber layer are spirally wound, and such composite yarn has almost no fuzziness, improved weaving performance, and improved pepper-and-salt appearance when the filament and discontinuous fibers are dyed in different colors. It is expected to have excellent performance, such as reduced skinnyness when saline and saline.

If the opening width h of the multifilament of the synthetic fiber does not overlap with the opening width H of the fleece of the discontinuous fiber or is separated from each other, the structure of the composite yarn is deformed so that a spiral structure cannot be formed, and such an effect is not obtained.

The feed location of the multifilament of synthetic fibers and the discontinuous fiber fleece can affect the structure of the yarns produced. When spinning a Z-twisted yarn, the multifilament of the synthetic fiber must move to the right relative to the discontinuous fiber fleece. In the case of spinning S-twisted yarns, the multifilament of the synthetic fibers must move to the left relative to the discontinuous fiber fleece. Thus, the intended yarn structure is obtained stably. In this case, the winding direction is clockwise for Z-twist and counterclockwise for S-twist.

The position for feeding the multifilament and the discontinuous fibers can be adjusted by adjusting the position of the opening electrode or by using special guides for the opened filament. The opening width of the multifilament can be adjusted by adjusting the voltage, supply tension, special guide for the filament, and the like.

The composite yarn according to the third aspect of the present invention can be manufactured using the apparatus shown in FIG.

In order to produce continuous and discontinuous composite yarns, the multifilament yarns A are unwound from the fern 8 and fed to the electrode 6 through the guide 9. The electrode 6 is a hollow electrode and charges static electricity to the multifilament yarn A passing through the electrode 6 to connect the yarn into individual filaments. The charged multifilament yarn passes through the guide ring 7 and is fed to the front roll 3 while adjusting the opening width and the supply tension.

Separately, a crude discontinuous fiber B is fed to the rear roll 1 and then drafted between the cradle 2 and the front roll 3. The discontinuous fibers B are then fed to the front roll 3 in the form of a fleece-forming bundle of discontinuous fibers B.

The opened or extended multifilament yarns A and the discontinuous fibers B of the fleece-shaped bundle are then mixed or entangled at the nip point of the front roll 3. In this step, the maximum opening width of the discontinuous fiber fleece is laminated at a distance of 10 to 90% of the maximum opening width of the multifilament.

The mixture of multifilament yarn A and discontinuous fiber fleece past the front roll 3 is twisted to form a special yarn structure with the cross section of the yarn having the center of the blended yarn of the filament and the peripheral layer of discontinuous fibers surrounding the center.

Eventually, the twisted yarn passes over the snail wire 4 and is wound around the winder with a loop and a traveler 5.

Now, a composite yarn according to the fifth aspect of the present invention will be described.

Composite yarns according to this aspect are continuous and discontinuous fiber yarns comprising acrylate yarns. The acrylate fiber used in this composite fiber is a crosslinked copolymer fiber of acrylic acid or a salt thereof with light metal and acrylamide, and has excellent temperature control, humidity control and conditioning performance.

However, as already described, acrylate fibers have very weak and nodular strengths that are about half to one third of the strength of other synthetic fibers used as coating materials such as polyester fibers.

Therefore, it is necessary to mix natural fibers and / or synthetic fibers with acrylate fibers. In order to manufacture a yarn having a high quality, it is necessary to form a composite fiber filament and a composite yarn. When a mixture of acrylate fibers and natural fibers and / or synthetic fibers is compounded with the filaments of synthetic fibers, the yarn may have a high strength and thus may be spun into lower number yarns, and the content of acrylate fibers in the composite yarn Can increase.

In order to obtain high quality yarns, a preferred composite composition is that a fiber bundle of a mixture of acrylate fibers and natural fibers and / or synthetic fibers is wrapped with synthetic fiber filaments.

Synthetic fiber filaments can be any filament used for coating. In terms of strength, polyesters and polyamides are preferred. It is preferable to have a filament number of 5 or more in terms of yarn quality.

The content of filaments in the composite yarn is preferably 10 to 35%. When this content is less than 10%, the performance and quality of the yarn may not be improved. If this content exceeds 35%, the quality of the fiber bundles containing acrylate fibers is very poor. As a result, the mixing ratio and spinnig count of acrylate fibers are very limited.

The mixing ratio of the acrylate fibers is preferably 5 to 45%, more preferably 10 to 40% from the viewpoint of the quality and functionality of the yarn. When the mixing ratio of the acrylate fibers is less than 10%, three performances, namely temperature control, humidity control, and conditioning performance, may not be sufficiently improved. When the mixing ratio of acrylate fibers exceeds 40%, yarn quality is greatly reduced, and a high ratio of such acrylate fibers is undesirable in terms of cost.

The composite yarn according to the fifth aspect of the invention preferably has a concentrated fine hair index of 200 fluff / 1000 m or less, more preferably 100 fluff / 1000 m or less.

In order to produce high quality fabrics, the composite yarn preferably has a concentrated fine hair index of 100 fluff / 1000 m or less, in particular 70 fluff / 1000 m or less. Since the acrylate fibers cannot be dyed, if the number of fine hairs is large, the concentrated hairs in the fabric appear white after dyeing the fabric. Thus, the quality of the fabric is very poor. Various test results show that the concentrated fine hair consists of acrylate fibers.

The mechanism for producing concentrated fuzz of acrylate fibers is assumed as follows:

During processing, the cutting of numerous discontinuous fibers is due to friction with metals and other fibers, causing bad drafting of the fibers, resulting in increased fiber defects, thus creating concentrated fuzz. The number of concentrated fine hairs can be easily counted because the concentrated fine hairs contain fine hairs that form the shape of a pill in the same area. Specifically, the number of concentrated fine hair counts as follows:

Wind the yarn on a yarn plate with a pitch of 20 yarn / inch. Make four spools. Then, the number of concentrated fine hairs found in the yarn is counted and converted into the number per 1000 m of yarn.

The production of concentrated fine hair is a very unusual phenomenon only when it contains tetravalent acrylate fibers. This phenomenon becomes more pronounced when the ratio of acrylate in the yarn increases, and the yarn containing no acrylate fiber is rarely troubled by the production of concentrated fine hair.

High quality yarns having a concentrated fine hair of less than 100 fluff / 1000 m can be produced by combining acrylate and filament. The composite configuration of the yarn is not limited, and the following configurations may be particularly advantageous.

The filaments supplied from the filament supply member and opened with the electric carding device are intertwined with the fiber bundles of acrylate fibers and natural (or synthetic) fibers supplied from the crude fiber supply member, and they are then twisted into high quality yarns (100 fluff / Having no more than 1000 m). The reason why high quality yarns are obtained may be that the concentrated fine hair of the acrylate fibers is stretched into individual filaments or wrapped into divided filaments.

Apart from the above method, the following method can be used to twist the continuous fiber bundles (A) of discontinuous fiber bundles (B) of acrylate fibers and natural (and) synthetic and synthetic fiber filaments to produce composite yarns. .

That is, after wrapping the substantially bundled multifilament yarns with the draft fiber bundles, they are twisted or temporarily twisted to form yarns wrapped with fine hairs. Alternatively, the drafted fiber bundles are wrapped with opened multifilaments and then twisted and wound or temporarily twisted to form fine yarn wrapped yarns. Composite yarns 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 also includes a filament supplied through a feed guide from a filament supply member and a fiber bundle of acrylate fibers and natural and / or synthetic fibers supplied from a crude fiber supply member. Tensioning the filaments via a tensioning mechanism, such as a tension roll, to the filaments, intertwining to form a first fiber bundle, which in turn comprises first fiber bundles and natural fibers and / or synthetic fibers but not acrylate fibers The second fiber bundles can be gathered apart from the first fiber bundles at a distance of 3 to 8 mm and actually twisted to produce them.

In the method, the first and second fiber bundles are braided such that the two types of fiber bundles are twisted together. Therefore, the disturbance of fiber orientation is suppressed, and the production of fine hair is suppressed. In addition, the first fiber bundle is wrapped with a second fiber bundle that does not contain acrylate fibers. These two effects work synergistically to produce high quality composite yarns.

Moreover, the high quality composite yarn according to the fifth aspect of the present invention comprises a fiber bundle of acrylate fibers and natural and / or synthetic fibers supplied from a crude fiber supply member with the filament supplied from the fiber supply member via a feed guide. Forming a fiber bundle intertwined while tensioning the filament through a tension mechanism such as a tension roll, and twining the filament around the fiber bundle through the guide roll from the outside of the front roll that does not tension the filament, It can be produced by twisting the fiber bundle produced in the step.

In this method, the filaments fed from the outside of the front roll almost completely cover the fiber bundles containing the acrylate fibers.

The composite yarn according to the seventh aspect of the present invention will be described in detail.

The synthetic fibers constituting the continuous fiber bundle (A) may be conventionally used synthetic fibers. Examples of the synthetic fibers include polyester filaments such as polyethylene terephthalate, polytrimethylene terephthalate and polytetramethylene terephthalate; Polyamide filaments of aliphatic polyamides and aromatic polyamides (eg nylon 6, nylon 66, etc.); Polyolefin filaments such as polyethylene, polypropylene and the like and the like. Among them, polyester fibers, especially polyethylene terephthalate fibers, are preferred in view of easy workability and cost.

In addition to conventional polyesters, copolyesters such as isophthalic acid, adipic acid, sebacic acid, naphthalene carboxylic acid, phthalic acid and the like, and alcohols such as propylene glycol, butylene glycol and diethylene glycol Copolymers may be included.

The fineness of the synthetic fibers is preferably 300 decitex or less. When the fineness exceeds 300 decitex, the fiber may not be opened enough unless high voltage is applied, thus increasing the manufacturing cost. In addition, composite yarns have large fineness when synthetic fibers having such large fineness are used. The fineness of the synthetic fibers is preferably 10 to 150 decitex, particularly preferably 15 to 100 decitex.

The synthetic fibers of the continuous fiber bundle (A) can be treated with an oil agent containing an antistatic agent.

Examples of antistatic agents include alkyl sulfonates, alkylbenzene sulfonates, alkyl sulfates, alkyl phosphates, and the like. They can be used independently or in mixtures of two or more.

Antistatic agents are commonly used to easily and electrically open synthetic fibers. The amount of antistatic agent is usually 12 to 50% by weight of the emulsion. If the amount of the antistatic agent is less than 12% by weight, the carding performance of the synthetic fiber is not improved and the composite yarn may have an unsatisfactory quality. If the amount of antistatic agent exceeds 50% by weight, the antistatic agent can very smoke during the stretching process. The amount of antistatic agent is preferably 15 to 40% by weight, more preferably 18 to 30% by weight.

The amount of emulsion applied to the synthetic fibers is preferably 1.1% by weight or less based on the weight of the synthetic fibers. If the amount of emulsion exceeds 1.1% by weight, the antistatic effect is increased, but the emulsion can flow down. Emulsions are used in appropriate amounts depending on the single fineness of the synthetic fibers. For example, when the fineness is large, the surface area of the fiber is reduced, and therefore a small amount of emulsion is preferred. When the shortness is small, the fiber surface area increases, so a large amount of emulsion is preferable. In an embodiment of the invention, when the mono fineness is 1 to 2.5 decitex, the amount of emulsion is preferably 0.2 to 1.1%, more preferably 0.3 to 0.9%, particularly preferably 0.4 to 0.7%. In this range the fibers are preferably opened or stretched.

When the emulsion is applied to the synthetic fibers, the fibers are effectively opened. In order to properly evaluate the opening performance of the synthetic fiber, the resistance at 25 ° C. and 40% RH is preferably used. When synthetic fibers have a resistivity of 8 x 10 ⁸ Ω or less at 25 ° C. and 40% RH, they have good carding performance even though they contain carbon black. When the resistivity has a resistivity in excess of 8 x 10 ⁸ Ω, the opening becomes less uniform, and there is a tendency for spots to occur when the continuous fibers are combined with the discontinuous fibers to form a composite yarn. In order to obtain a resistivity of 1 × 10 ⁸ Ω, a relatively large amount of an oil agent, that is, an antistatic agent, is used for the synthetic fiber, and the opening performance tends to be poor. Thus, the resistivity is preferably between 1 x 10 ⁸ Ω and 6 x 10 ⁸ Ω, more preferably between 1 x 10 ⁸ Ω and 4 x 10 ⁸ Ω.

Specific examples of the antistatic agent include poly (oxyethylene) alkylamine, poly (oxyethylene) alkylamide, poly (oxyethylene) alkyl ether, poly (oxyethylene) alkylphenyl ether, glycerin fatty acid ester, sorbitan fatty acid ester, alkylsulfo Nate salts, alkylbenzenesulfonate salts, alkylsulfate salts, alkylphosphate salts, quaternary ammonium chlorides, quaternary ammonium sulfates, quaternary ammonium nitrates, alkylbetaines, alkylimidazolines, alkylalanines and the like do. They can be used independently or as a mixture of two or more. Among them, anion antistatic agents such as alkylsulfonates, alkylbenzenesulfonate salts, alkylsulfate salts and alkylphosphate salts are preferred. Particular preference is given to sulfonate metal salts.

The emulsions used in the synthetic fibers preferably comprise 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 portion to which the fiber is in contact may be so large that it may be the cause of the formation of fine hairs. When the amount of the emulsifier is less than 5 parts by weight, it may not be uniformly mixed with water when the emulsion is diluted in water. Therefore, the emulsion tends to form spots on the yarns, and the yarns also have fine hairs or are cut off.

More preferably, the emulsion comprises 50 to 60 parts by weight of oil component, 10 to 20 parts by weight of emulsifier and 18 to 30 parts by weight of antistatic agent.

Conventional oil components can be used as the basic oil component of the emulsion used in the present invention. For example, a suitable mixture of mineral oils and fatty acid esters can be used.

Emulsifiers may also be conventional emulsifiers, examples of which include glycerin fatty acid esters, sucrose fatty acid esters, sorbitan fatty acid esters, propylene glycol fatty acid esters, POE ether-added oils, PEG ester-added oils, lecithin and the like. do. They can be used as their mixture. Among them, PEG dioleate, fatty alcohols and metal salts thereof are particularly preferred.

The synthetic fibers used in this embodiment may preferably contain fine particles. Fine particles can reduce the slip or smoothness of the fibers, but the use of emulsions optimizes the coefficient of friction and improves the opening performance.

The fine particles can be any fine particles usually compounded in the fiber, such as pigments, matting agents, antimicrobial agents, antistatic agents and the like. Fine particles colored with carbon black are preferred because the fibers containing such fine particles exhibit excellent carding performance, thereby suppressing spots resulting from fiber mixing and reducing color spots. The fibers may contain additives and other polymers such as matting agents, antimicrobial and antistatic agents other than those exemplified above. In addition to carbon black, the pigment may be any of other colors.

In order to add fine particles to the fiber, a synthetic resin matrix polymer containing 5 to 40% by weight of carbon black in the case of carbon black and a synthetic resin matrix polymer containing no carbon black are mixed and melt-spun. To obtain dope black-dyed polyester fibers. In this case, the amount of carbon black is usually 0.5 to 2.0% by weight based on the weight of the weight of the carbon black is less than 0.5% by weight, the color spot can be noticed. If the amount of carbon black exceeds 2.0% by weight, the carbon black will not be mixed well with the polymer, so that unevenness can be noticed.

The deep concentrate and the matrix polymer can be mixed by any conventional method. For example, deep color concentrate pellets and pellets of matrix polymer are mixed prior to melting and then the mixture is melted. Alternatively, the pellets of the deep color concentrate and the pellets of the matrix polymer are melted separately, and then the melt is statically mixed with a static mixer just before spinning. After mixing, the compound is processed by conventional melt spinning methods to obtain fibers. The cross section of each fiber can have any shape, for example round, odd (profile) shape, hollow shape and the like.

The carbon black used in the present invention may be channel black, furnace black and the like. When the main particle size of the carbon black is too small, the carbon black particles are easily aggregated when compounded in polyester such as polyethylene terephthalate type copolyester, and the spinning of the compound can be difficult. When the main particle size of the carbon black is too large, the depth of the black color decreases. Therefore, the main particle size of carbon black is preferably 10 to 40 nm. When the major particle size is less than 10 nm, handling of carbon black is difficult. When the primary particle size exceeds 40 nm, the nozzle back pressure increases during the spinning process, resulting in poor workability and causing trimming.

Discontinuous fiber bundles (B) comprising natural fibers and / or synthetic fibers are preferably crude fiber supply members comprising wool, cotton, silk, hemp, synthetic fiber staples, rayon staples, acetate staples and mixtures thereof. Supplied from. Among them, wool is more preferred.

The composite yarn according to the seventh aspect of the present invention preferably has a fine hair index of 1000 fluff / 10 m or less for fine hair having a length of 1 mm or more. To produce high quality fabrics, the fine hair index is preferably 700 fluff / 10 m or less. When the number of fine hairs is large, the concentrated hairs in the fabric appear white after the dyeing of the fabric, and thus the quality of the fabric is very poor.

The composite yarn according to the seventh aspect of the present invention may be prepared as follows:

The substantially bundled multifilament yarns are wrapped with draft fiber bundles and then twisted or temporarily twisted to form fine hair wrapped yarns. Alternatively the drafted fiber bundles are wrapped with opened multifilament and then twisted or wound or temporarily twisted to form fine hair wrapped yarns.

Moreover, the high quality composite yarn according to the seventh aspect of the present invention twists the filaments A supplied from the filament supply member through the feed guide with a tension mechanism such as a tension roll and twists the fibers with the natural and / or synthetic fiber bundles. Prepared by twisting the fiber bundle produced in the previous step by forming the bundle and twining the filament around the fiber bundle (B) from the outside of the front roll through the guide roll without tensioning the filament do.

In this way, the filaments fed from the outside of the front roll completely cover the fiber bundle (B).

In addition to the above method, the composite yarn can be produced by continuously opening the synthetic fiber filament (A). In order to charge the synthetic fiber filament (A) and to continuously open the filament, a truncated cone-shaped electrode such as that disclosed in JP-A-11247 can be used. In addition to the use of carding electrodes, the fibers can be opened or extended with corona discharge, ionized air media or by contacting the fibers with high pressure electrodes. The continuous synthetic fibers A supplied from the filament supply member and opened with the electric fiber carding device are intertwined with the fiber bundles B of natural and / or synthetic fibers supplied from the crude fiber supply member, and then Twisted to obtain high quality yarns having a fine hair index of 700 fluff / 1000 m or less.

The position at which the continuous synthetic fibers (A) and the discontinuous fiber bundles (B) are fed can be adjusted by adjusting the position of the carding electrodes or by using special guides for the carded filaments. The opening width of the continuous synthetic fiber (A) can be adjusted by adjusting the voltage, supplying tension, special guide for filament, and the like.

Continuous and discontinuous composite yarns of the present invention can be made using the apparatus shown in FIG.

In order to produce continuous and discontinuous fiber composite yarns, the multifilament yarns A are unwound from the fern 8 and transferred to the electrode 6 through the guide 9. The electrode 6 is a hollow electrode and applies static electricity to the multifilament yarn A passing through the electrode 6, so that the yarn is connected to the individual filaments. After the charged multifilament yarns pass through the guide ring 7, they are fed to the front roll 3 while adjusting the opening width and feeding position.

Separately, the crude discontinuous fibers B are fed to the rear roll 1 and then drafted between the cradle 2 and the front roll 3. The discontinuous fibers B are then fed to the front roll 3 in the form of a fleece-shaped bundle of discontinuous fibers B.

The opened or stretched multifilament yarn A and the discontinuous fibers B of the fleece bundles are then mixed or entangled in the nip position of the front roll 3. In this step the center of the filament is substantially aligned with the center of the discontinuous fiber fleece while limiting the opening width of the multifilament to 50-300% of the maximum width of the discontinuous fiber fleece.

The mixture of multifilament yarn A and the discontinuous fiber fleece passing through the front roll 3 is twisted to form a yarn structure having a cross section consisting of a uniform blend of filament and discontinuous fibers.

Finally, the twisted saga is wound around the snail wire 4 and wound around the winder 10 with a loop and a traveler 5.

In the composite yarn according to the seventh aspect of the present invention, the discontinuous fiber bundles (B) are uniformly mixed with the continuous synthetic fibers (A) having excellent carding performance. Therefore, the composite yarn has almost no fuzz, and has a uniform pepper-and-salt appearance in different colors when the synthetic fiber A is a dope dyed fiber. Moreover, since the number of fine hairs is small, the yarn has improved weaving performance. Composite yarns may be processed into the form of plain, twill, runner or the like, or in the form of knits, for example warp knits and weft knits. These fabrics have good cardiac performance, lack skintness, and also have improved texture and are particularly suitable for the manufacture of black dress suits.

In a synthetic fiber according to an eighth aspect of the invention, an emulsion containing from 12 to 50% by weight of an antistatic agent is attached to the fiber in an amount of up to 1.1% of the total fiber weight and the fiber is 8 at 25 ° C. and 40% RH. x 10 ⁸ Ω or less.

Synthetic fibers used in connection with this embodiment mean conventional synthetic fibers, examples of synthetic fibers being the same as those exemplified in connection with the continuous synthetic fibers (A) of the composite yarn according to the seventh aspect of the present invention.

In this embodiment the emulsion containing the antistatic agent, the amount and resistance of the emulsion used are the same as described in connection with the composite yarn according to the seventh aspect of the invention.

The synthetic fibers used in this embodiment preferably contain fine particles. Fine particles can improve the slippage or smoothness of the fiber surface, but the use of emulsions optimizes the coefficient of friction and improves the opening performance.

The fine particles can be any fine particles that are usually compounded in the fiber, such as pigments, matting agents, antimicrobial agents, antistatic agents and the like. Fine particles colored with carbon black are preferred because the fibers containing such fine particles exhibit excellent carding performance, thereby suppressing spots resulting from fiber mixing and reducing color spots. The fibers may contain additives and other polymers such as matting agents, antimicrobial and antistatic agents other than those exemplified above. In addition to carbon black, the pigment may be any of other colors.

In order to add fine particles to the fibers, a synthetic resin matrix polymer containing no carbon black and a synthetic resin master batch containing 5 to 40% by weight of carbon black in the case of carbon black are mixed and melt spun To obtain dope black-dyed polyester fibers. In this case, the amount of carbon black is usually 0.5 to 2.0% by weight based on the weight of the fiber. If the amount of carbon black is less than 0.5% by weight, the color spot can be noticed. If the amount of carbon black exceeds 2.0% by weight, the carbon black will not be mixed well with the polymer, so that unevenness can be noticed.

The deep concentrate and the matrix polymer can be mixed by any conventional method. For example, deep color concentrate pellets and pellets of matrix polymer are mixed prior to melting and then the mixture is melted. Alternatively, the pellets of the deep color concentrate and the pellets of the matrix polymer are melted separately, and then the melt is statically mixed with a static mixer just before spinning. After mixing, the compound is processed by conventional melt spinning methods to obtain fibers. The cross section of each fiber can have any shape, for example round shape, strange (profile) shape, hollow shape and the like.

The carbon black used in the present invention may be any carbon black commonly used. Type and particle size have already been described.

The fineness of the synthetic fibers may be the same as described in connection with the synthetic fibers according to the seventh aspect of the present invention.

The electric carding device according to the present invention will now be described with reference to the drawings.

<First Embodiment of Opening Device>

Figure 3 schematically shows a cross section of a first embodiment of an electric carding machine according to the invention.

Moreover, the opening device 1 has a hollow cylindrical electrode 3 which substantially passes along the central axis of the main body 2. The electrode 3 is connected to a power source 4, which applies a voltage to the electrode 3. The multifilament yarn passes through the hollow portion of the electrode 3, which charges the yarns.

The opening device 1 is made of an insulating material and has a lid member 5 provided to the rear with respect to the yarn running direction. The lid member 5 has an opening through which yarns are introduced into the electrode 3. In addition, the carding device 1 has a ground ring 6 forward with respect to the yarn running direction. 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 ground ring is larger than the outer diameter of the dead exit 3B of the electrode. Preferably, the inner space of the ring 6 has a truncated cone shape, and the inner diameter of the front end 6B is larger than the inner diameter of the rear end 6A.

The opening device 1 is installed along a vertical line, ie the lid member 5 faces upwards, and the grounding member 6 faces downward, as shown in FIG. 2 so that the multifilament yarn moves downward and is stably opened or extended. Headed. However, the opening device 1 can be installed in any direction other than the vertical direction.

In order for the multifilament yarn to pass through the electrode, the electrode 3, which applies a voltage, has a hollow cylindrical shape. Although the cross-sectional shape of the electrode 3 of the plane perpendicular | vertical to the advancing direction of a yarn is not restrict | limited, It is preferable that it is circular so that an electrode may not interfere with the progress of a yarn.

In order to maintain a stable opening of the multifilament yarn, the length of the electrode 3 is usually 15 to 70 mm, preferably 20 to 60 mm, more preferably 25 to 50 mm, and the inner diameter of the electrode 3 is usually 0.3 to 6 Mm, preferably 0.5 to 3 mm, more preferably 0.8 to 2 mm.

In the opening device 1, a voltage is applied from the power supply 4 to the electrode 3, and the multifilament passing through the electrode in turn is charged to the electrode 3. The material of the electrode 3 is not limited as long as the electrode 3 can charge the multifilament yarns. Examples of the material of the electrode 3 include conductive metals such as iron, copper, silver, etc., other conductive materials such as conductive plastics, metal powders compounded therein, plastics or ceramics containing others do.

The ground ring 6 is provided downstream of the electrode 3 relative to the yarn propagation direction. The ring 6 is grounded to the ground and has a substantially zero electrical potential. Since the multifilament yarns pass through the electrode 3, and after being charged, pass through the ground ring 6, the charged filaments of the multifilament yarns are attracted to the ground ring 5. Therefore, opening can be facilitated. The material of the ground ring 6 is not limited if the ring can attract the charged filaments. Examples of the material of the ring 6 include metals, such as iron, copper, silver, and other conductive materials such as conductive plastics, metal powders compounded therein, plastics or ceramics containing the others.

In order to facilitate the opening of the multifilament yarns, the shape of the inner space of the ground ring 6 is such that the front end of the space present in the downstream direction with respect to the direction of travel of the yarn is the rear end of the space present in the upstream direction with respect to the direction of travel of the yarn. Larger is preferred. The shape of the cross section of the grounding ring 6 in a plane perpendicular to the direction of travel of the yarn is not limited, but is preferably circular so that the multifilament yarn can be evenly opened or unfolded in all directions of the cross section plane.

In order to stably open the multifilament yarns, the inner diameter of the front end 6B of the ground ring 6 is usually 6 to 25 mm, preferably 8 to 22 mm, more preferably 10 to 20 mm, and the rear end 6A. The inner diameter of) is usually 5 to 24 mm, preferably 6 to 20 mm, more preferably 7 to 15 mm. The distance between the front end 6B and the rear end 6A is usually 3 to 25 mm, preferably 5 to 20 mm, more preferably 7 to 15 mm.

The yarn outlet 3B of the electrode is between a position of 5 mm from the rear end 6A of the ground ring in the reverse direction of yarn travel to a position of 23 mm from the rear end 6A of the ground ring in the yarn running direction. Preferably the yarn outlet 3B of the electrode is between a position of 3 mm from the rear end 6A of the ground ring in the reverse direction of the yarn run to a position of 20 mm from the rear end 6A of the ground ring in the yarn run direction. do. More preferably, the yarn outlet 3B of the electrode is present at a distance of 0 to 18 mm from the rear end 6A of the ground ring in the yarn running direction. In either case, the yarn inlet 3A of the electrode must be upstream of the rear end 6A of the ground ring in the yarn running direction, and the yarn outlet 3B of the electrode is the front end 6B of the ground ring in the yarn running direction. It must be upstream of).

Preferably, the electrode of the carding device 1 comprises a main body 2 made of an insulating material; And a yarn introduction opening, which is also made of an insulating material and surrounded by a lid member 5 provided on the rear face of the electrode 3 with respect to the yarn travel direction through the hollow passage of the electrode. Thus, the worker does not touch the electrode 3, thus improving safety. The opening device 1, the main body 2 and / or the lid member 5 may not be an essential element.

The voltage applied to the electrode 3 can be positive or negative. The absolute value of the voltage applied to the electrode 3 is usually 1 to 20 mA, preferably 1 to 10 mA, more preferably 2 to 7 mA.

The traveling speed of the multifilament yarns passing through the electrode is usually 0.03 to 0.70 m / sec, preferably 0.05 to 0.55 m / sec, more preferably 0.07 to 0.45 m / sec. In connection with this, the rotational speed of the spindle winding the multifilament yarn is usually 3000 to 15,000 rpm, preferably 4000 to 13,000 rpm, more preferably 5000 to 11,000 rpm. The tension applied to the multifilament yarn is 10 gf (gram-force) or less, preferably 5 gf or less, more preferably 2 gf or less.

Multifilament yarns are continuous fibers comprising synthetic fibers already described in connection with the composite yarn according to the invention.

Second Embodiment of Opening Device

When the carding machine of the first embodiment is used, the multifilament yarns are fully opened or extended, and the extended filaments are in continuous contact with the ejection openings of the electrodes and the electrodes tend to wear out. When a hard tube having an internal diameter at its yarn inlet equal to or greater than the internal diameter of the yarn outlet of the electrode is attached to the yarn outlet of the electrode, the unfolded filament does not directly contact the electrode, thus preventing wear of the electrode.

In principle, a hard tube is attached to the electrode in order to contact the hard element with at least the front end of the threaded outlet of the electrode so as to prevent direct contact of the ejection opening of the electrode with the straight filament.

Hard tubes are generally hollow cylinders having yarn inlets and yarn outlets having the same inner diameter. However, the inside diameter of the yarn inlet and the outlet of the hard tube may be slightly different so long as the contact of the filament to the yarn outlet of the electrode is prevented.

In one embodiment of the second embodiment of the carding machine, the yarn outlet of the electrode is connected to or inserted into the yarn inlet of the hard tube such that the yarn outlet of the hard tube crosses the outlet of the electrode in the yarn running direction.

4 schematically shows an enlarged cross section of the electrode 3 and the hard tube 7 applying the voltage of this embodiment of the carding machine near the yarn outlet. The distance between the yarn outlet 3B of the electrode connected to or 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. It is as follows.

Preferably, the hard tube 7 is made of a material that is hard enough to come into contact with the multifilament yarns. Hard tubes, for example, may be 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 silicon carbide.

More parts of the electrode 3 are inserted into the hard tube to protect the electrode 3. In this case, the electrode is inserted into the hard tube by a distance from the external power source to the electrode so that a voltage can be applied. As more of the electrode 3 is inserted into the hard tube 7, the rear part of the electrode 3 is not inserted into the hard tube 7, for example, in the oblique direction, in order to leave the exposed part connected to the power source. Do not. Alternatively, a window is made in the middle of the hard tube 7 and an electrode is connected to the power source through the window.

In order to prevent the resemblance of the electrode to the connected filaments of the multifilament yarns, at least the inner surface of the outlet region of the electrode 3 may be made of a rigid material instead of using hard tubes. For example, the inner surface of the electrode is coated with a rigid layer of diamond or silicon carbide, for example.

The yarns prepared in Examples 7-10 had a small concentrated fine hair index and therefore had a high quality dyed fabric, ie low whitening. In contrast, the yarn of the comparative example had a large concentrated hairiness index.

Example 11

The dough sheet fabric 28G was woven using the mixed yarns or composite yarns of Examples 7 to 10 and Comparative Examples 9 to 15, respectively, and then dyed to navy-blue with a high pressure liquid flow dyeing machine.

Example 12

Polyethylene terephthalate pellets (95 parts by weight) having an intrinsic viscosity of 0.64 and pellets of polyester composition (deep concentrate) (80% by weight of ethylene terephthalate copolymer having an intrinsic viscosity of 0.64 and carbon having an average particle size of 22 nm) Consisting of 20% by weight of black) (5 parts by weight) was mixed, then melted and kneaded with kneader. The melt was then discharged at a rate of 20 g / min through a 24-hole spinneret having a diameter of 0.3 mm each, and drawn at a rate of 1100 m / min.

The unstretched yarn was stretched to draw ratio 3.3 by conventional methods to obtain dope black-dyed yarn (56 decitex / 24 filaments).

As an emulsion, emulsion A comprising 57 parts by weight mineral oil, 23 parts by weight sodium cetylsulfonate, 13.5 parts by weight PEG (13) dioleate, 4 parts by weight oleyl alcohol and 2.5 parts by weight potassium oleate was used.

Emulsions were used by the oil ring roll method in an amount of 0.7% by weight based on the weight of the black-dyed yarn.

Then, using the black-dyed yarn as the multifilament yarn (A), the composite yarn of this example was made with the apparatus shown in FIG.

As the coarse fiber B, 1 / 3.0 Nm of carded coarse fiber is fed from the rear roll 1 to the apparatus shown in FIG. 2 and between the rear roll 1 / cratle 2 and the front roll 3. The total draft ratio was drafted at 17.1.

Separately, the multifilament yarn A was supplied to the electrode 6 through the guide 9. Using the electrode 6, a voltage of -3000 V was applied to the multifilament yarn A to open the yarn into individual filaments. The filament is then passed through the guided fiber 7 and the feed position of the filament is adjusted so that the center of yarn A is substantially aligned with the center of the fleece of fiber B. Opening filament was fed to the front roll 3, and it was entangled with the coarse fiber B of a fleece state, adjusting the opening width of (A) to 200% of the maximum width of the fleece of the fiber (B). The entangled yarns and fibers were then twisted with a twist of 900 T / M (Z) to form a mixed yarn with a number of 1/40 Nm and wound around the winding machine 10 in the form of a cobb.

When the cross section of the blended yarn was observed under a microscope, the parent fibers and the dope black-dyed filaments were uniformly mixed as shown in FIG. 5.

Example 13

A composite yarn was prepared in the same manner as in Example 12 except that the amount of carbon black in the deep color concentrate was changed to 30% by weight.

Comparative Example 16

Instead of emulsion A contains 60 parts by weight of mineral oil, 10 parts by weight sodium cetylsulfonate as antistatic agent, 20.5 parts by weight PEG (13) dioleate as emulsifier and 9.2 parts by weight oleyl alcohol and 0.3 parts by weight potassium oleate as additive A composite yarn was prepared in the same manner as in Example 12, except that emulsion C was used.

Comparative Example 17

A composite yarn was prepared in the same manner as in Example 12, except that Oil A was used in the yarn at 1.5 wt%.

Example 14

Except for using emulsion A, which contains 50 parts by weight of 2-ethylhexyl caprylate, 7 parts by weight of alkyl modified silicone oil, 23 parts by weight of sodium cetylsulfonate and 20 parts by weight of POE alkylphenyl ether. Composite yarns were prepared in the same manner as in Example 12.

The compositions of emulsions A, B and C are summarized in Table 8.

Table 9 summarizes the amount and type of emulsion used, the resistance of composite yarns and the index of fine hairs.

Example number emulsion Amount of emulsion (% by weight) Resistance (x 10 ⁸ Ω) Fine hair index (/ 10m) 1 mm or more 3 mm or more Example 12 A 0.7 0.7 604 124 Example 13 A 0.7 0.6 524 176 Example 14 B 0.7 0.2 248 95 Comparative Example 16 C 0.7 19 914 289 Comparative Example 17 A 1.5 0.03 820 415

As can be seen from the results shown in Table 9, when using emulsions, the dope black-dyed fibers were continuously opened, and the dope black-dyed fibers and mock fiber bundles were uniformly mixed and twisted. Thus, the fine hair index decreased. However, if the amount of emulsion is small or too high, the fibers may not be opened enough. Thus, the fibers are not uniformly mixed and the fine hair index may increase.

Example 15

Example except that the cotton fiber of 100 grain / 15 yard, the drafting ratio was changed to 36.4, and the entangled fiber was twisted at a twist of 20.27 t / in (Z) to form a blended yarn having a count of 30/1. Composite yarns were prepared in the same manner as in 12.

The obtained blended yarn had a fine hair index of 615 fluff / 10 m.

Example 16

Plain weave was woven using the blended yarns of this example as warp (no grass) and weft yarns. The fabric had excellent performance such as low shinning, high air permeability, low skintness in case of pericarditis, good pericardial performance and good weaving performance.

The melt was then discharged at a rate of 20 g / min through a 24-hole spinneret having a diameter of 0.3 mm each, and drawn at a rate of 1100 m / min.

The unstretched yarn was stretched to draw ratio 3.3 by conventional methods to obtain dope black-dyed yarn (56 decitex / 24 filaments).
