Description

  The present invention relates to a woven fabric composed of long and short composite spun yarns which are wound while being drawn by superimposing drafted short fiber bundles and opened synthetic fiber multifilament yarns, and physical properties of the synthetic fiber multifilaments The present invention relates to providing a woven fabric that takes advantage of the features of the surface and does not impair the unique texture of wool.

Conventionally, as a means for enhancing the durability of a fabric while taking advantage of the characteristics of natural fibers, a method of combining synthetic fiber filaments with natural fibers (for example, see Patent Document 1) or a method of blending synthetic fiber staples with natural fibers ( For example, Patent Document 2) is used.

  Composite spun yarns composed of natural fibers and synthetic fiber filaments are used in jerseys and fabrics because of their excellent durability and light weight. In particular, composite spun yarns composed of wool and synthetic fiber filaments are usually fine counts and strong twists, and because they produce fabrics with excellent breathability and lightness, they are often used in suits and formal wear for spring and summer. Has been. Also, in the field of worsted fabrics, weaving is generally performed without gluing, so composite spun yarns and untwisted yarns of single filaments and various filaments can be used so that weaving can be done without glue. Generally, the twist number is a strong twist. For this reason, fabrics made from composite spun yarns and woven yarns of single filaments and various filaments are ideal for spring and summer materials because of their high breathability and light weight, but the texture is stiff and the materials for fall and winter As it was not usable.

In addition, the method of blending synthetic fiber staples with natural fibers is performed for the purpose of reducing the price and improving the physical properties of the cotton spinning, the worsted spinning, and the spinning spinning. In particular, because of its high durability, fabrics using blended yarns of wool and polyester staples are often used in uniforms and school uniforms. However, these fabrics have increased wear resistance and tear strength, but the occurrence of pilling increases, so it is possible to blend polyester staples with high anti-pill properties, increase the twist number of the blended yarn, It is necessary to take measures such as careful cutting and gas burning in the textile arrangement process. However, when polyester-based staples with high anti-pill properties are blended, even if the texture and anti-pill properties are improved, the wear strength is naturally reduced, and it is difficult to obtain a fabric having both the feel and physical properties. . In addition, even when the number of twists in the blended yarn is increased, or when careful cutting and gas firing is performed in the arrangement process, the anti-pill property is improved, but the texture of the fabric becomes stiff due to the influence of the number of twists and gas firing. It was not possible to obtain a woven fabric having both texture and physical properties.
Japanese Patent Laid-Open No. 10-226938 JP 2001-11749 A

  The present invention was devised to eliminate the above-mentioned conventional drawbacks, and its purpose is to provide a woven fabric that does not impair the natural texture of natural fibers while taking advantage of the physical properties of synthetic fibers. There is.

As a result of intensive studies in order to solve such problems, the present inventors have found that the problem can be solved by forming a woven fabric using long and short composite spun yarns twisted more than twin yarns. That is, the present invention has the following configuration.
1. It is a woven fabric containing at least a part of a yarn obtained by arranging two or more long and short composite spun yarns and twisted, and the cross section of the long and short composite spun yarns shows that the synthetic fiber filaments and the short fibers are uniformly mixed. Characteristic long and short composite spun yarn fabric.
2. The long / short composite spun yarn fabric according to the first aspect, wherein a single yarn of the long / short composite spun yarn constituting the fabric has a twist coefficient of 40 to 90.
3. The long / short composite spun yarn fabric according to the above first or second, wherein the twist coefficient is 40 to 110 when two or more long / short composite spun yarns are aligned and twisted.
4. The long / short composite spun yarn fabric 5 according to any one of the first to third aspects, wherein the synthetic fiber multifilament group is electrically opened and mixed with the short fiber group. The synthetic fiber multifilament group is a polyester-based multifilament group selected from the group consisting of a polyethylene terephthalate multifilament group, a polytrimethylene terephthalate multifilament group, and a polybutylene terephthalate multifilament group. Long and short composite spun yarn fabric.
6. The short / long composite spun yarn fabric according to the fourth or fifth aspect, wherein the short fiber group is a wool single fiber group.
7. The long / short composite spun yarn fabric according to any one of the above fourth to sixth, wherein the ratio of short fibers to the entire long / short composite spun yarn is 50 to 95%.
8. The long / short composite spun yarn fabric according to any one of the first to seventh aspects, wherein the wear strength is 40,000 times or more.
9. The long / short composite spun yarn fabric according to any one of the first to eighth aspects, wherein the pilling characteristic is 4th or higher.

  By weaving two or more long and short composite spun yarns according to the present invention and weaving them by weaving them, weaving is possible even if they are not strong twisted yarns while taking advantage of the physical properties of synthetic fibers such as wear characteristics. There is an advantage that a softer texture can be obtained, and a fabric suitable as an autumn / winter material that does not impair the natural texture of natural fibers can be obtained.

  The woven fabric of the present invention preferably contains at least a part of so-called twin yarn or triplet yarn obtained by twisting two or more single yarns of long and short composite spun yarns. When using single yarns, weaving without gluing is generally used in the field of worsted fabrics, so long and short composite spun yarns can be woven with various types of worsted yarns so that weaving can be done without glue. The twisted yarn with the filament also needs to be strongly twisted. In the case of sweet twisting without strong twisting, there are problems that the weaving property is remarkably deteriorated and the quality of pilling, snag, etc. is inferior even as a woven fabric. If it is a strong twisted fabric, there is no problem in operability, and the fabric is highly breathable and lightweight, so it is ideal as a spring / summer material, but the texture is hard and cannot be used as an autumn / winter material. there were. Even if the present invention is not strongly twisted, for example, two or more long and short composite spun yarns (single yarns) having a twist number of 40 to 90 may be arranged and twisted. When the twist coefficient is less than 40, the spinnability is not so preferable, and the woven fabric characteristics such as pilling are not so preferable. On the other hand, if it exceeds 90, the spinnability and pilling characteristics are improved, but the texture becomes hard like a conventional woven fabric made of strong twisted yarn. If you use single yarns of long and short composite spun yarns, we cannot actually weave with spun yarns with the above twist coefficient, but weaving is good without twisting two or more single yarns, and weaving is good. It is possible to make the fabric without

  The long and short composite spun yarn used for the woven fabric of the present invention is a composite spun yarn in which long fibers are combined in a short fiber spinning process, and the long fibers and short fibers are almost irregularly mixed and uniformly mixed. It is. Synthetic staple fibers and natural staple fibers blended yarns and stranded yarns of single filaments and various filaments are undesirable because the texture becomes stiff and pilling increases. Is not preferable.

  The configuration of the cross section of the long and short composite spun yarn used for the fabric of the present invention is preferably formed by substantially uniformly mixing synthetic fiber filaments and short fibers. In this case, the substantially uniform mixture exists in the state where two types of yarns are dispersed, unlike the yarns that are concentrated on the part where the filaments are present, such as core yarns and twisted yarns. Means that. If it is a core yarn, spinning is possible even if the twisting factor is lowered. However, there is a problem in that the filament is exposed because the synthetic fiber multifilament and the short fiber are displaced in the subsequent process of twisting, combining, and twisting. However, if it is a finely spun and twisted yarn, spinning itself is difficult if it is sweet-twisted. Even if it is sweet-twisted because it is uniformly dispersed, the above-mentioned problems do not occur in the spinning process, the stranding yarn, the combined yarn, and the twisting yarn process.

  It is preferable that the twist coefficient is 40 to 110 when two or more long and short composite spun yarns (single yarn) used in the fabric of the present invention are aligned and twisted. When the twist coefficient is less than 40, fluff is likely to occur, and the weaving property and pilling are likely to deteriorate, which is not preferable. If it exceeds 110, the yarn is tightened and the texture is likely to become hard, which is not preferable. More preferably, it is 50-90.

  The long and short composite spun yarn used in the fabric of the present invention is preferably a long and short composite spun yarn in which a synthetic fiber multifilament group and a short fiber group are electrospread and mixed. It is because it becomes easy to form a uniform mixed layer by electrospreading mixing. Although the scraping method can be considered as the opening method, since the opening is insufficient and not stable, troubles frequently occur in the twisting process and the weaving process, and further, the problem of pilling cannot be solved.

  The synthetic fiber multifilament constituting the long and short composite spun yarn used in the fabric of the present invention is preferably a polyester multifilament, and representative examples include polyethylene terephthalate multifilament, polytrimethylene terephthalate multifilament, and polybutylene terephthalate multifilament. be able to. Nylon, which is a polyamide fiber, has a low heat resistance and is not preferable because the nylon fiber is easily shrunk in a fabric arranging process, a process of thermally bonding an interlining, or a pressing process. Polyolefin fibers are not preferred because they are not dyed. Polyacrylonitrile fibers are less preferred in terms of product life because of their low wear strength.

  The short fibers constituting the long and short composite spun yarn used for the fabric of the present invention are preferably wool short fibers. As the yarn of wool becomes thinner, the price increases exponentially. This is because when it gets thinner, it gives a silky luster and the texture becomes softer. This is because the long and short composite spun yarn of the present invention can be thinned as a yarn even if ordinary wool is used, so that the added value can be greatly improved.

  In the long and short composite spun yarn used for the fabric of the present invention, it is preferable that the short fiber is 50 to 95% by weight of the total proportion of the long and short composite spun yarn. If it is less than 50% by weight, it is difficult to make use of the natural fiber texture, and if it exceeds 95% by weight, the entanglement between the short fiber and the multifilament is deteriorated, which is not preferable.

  Further, as the long and short composite spun yarn preferably used in the present invention, the fineness (decitex) of the synthetic fiber multifilament yarn is preferably 11 to 110 dtex, and the fineness (decitex) of the single yarn constituting the synthetic fiber multifilament ) Is preferably 0.1 to 6.6 dtex. Although the multifilament is mixed with the short fiber group, the woven fabric obtained by making the thickness of the composite yarn obtained by mixing within a certain range can be finished into a preferable one. If it is less than 11 decitex, it is difficult to obtain a composite effect, and if it exceeds 110 decitex, it is difficult to feel the texture of natural fibers, which is not preferable.

  In order to make use of the natural fiber texture, it is preferable that the single filament fineness of each filament is 0.1 to 6.6 decitex, in addition to setting the total fineness (decitex) of the multifilament to the above preferred range. More preferably, it is in the range of 0.2 to 3.3 dtex. Here, if it is less than 0.1 dtex, the stiffness is lost, and if it exceeds 6.6 dtex, the texture becomes hard, which is not preferable.

  The woven fabric of the present invention preferably has a pilling of 4.0 grade or higher in JIS-L-1076 Method A (ICI method) 20 hours. If it is less than 4.0 grade, pilling is likely to occur during actual wearing, which is not preferable.

  It is preferable that the woven fabric of the present invention has an abrasion strength of 40,000 times or more by the E method (Martindale type method) of JIS-L-1096. This is not preferred when long and short composite yarn fabrics are used for school uniforms, and if less than 40,000 times, troubles such as tearing and thinning of the fabric (translucency) are likely to occur during actual wearing. The higher the wear strength, the better, but it is usually 100,000 times or less.

  The above-mentioned long and short composite spun yarns having a unique sweet twist of the present invention are prepared by electrospreading synthetic fiber multifilament yarns and superimposing and spinning just before the draft short fiber group and the front roller. It is preferable to do.

  In the method for producing a long / short composite spun yarn of the present invention, when the synthetic fiber multifilament yarn is electrically opened and overlapped immediately before the front roller with the drafted short fiber group, the center of the short fiber fleece and the opening are opened. It is preferable to overlap the centers of the multifilaments.

  The opening width of the synthetic fiber multifilament is preferably equal to or greater than the maximum width of the short fiber fleece.

  Determination of the supply position of the synthetic fiber multifilament and the short fiber fleece can be adjusted by using the position of the opened electrode or a dedicated guide for the opened filament. The opening width of the synthetic fiber multifilament is adjusted by adjusting the opening voltage, supply tension, filament dedicated guide, and the like.

  The long and short composite spun yarn of the present invention can be manufactured using, for example, the apparatus shown in FIG. That is, according to FIG. 2, the apparatus arranges the back roller 1, the cradle 2, and the front roller 3 in this order, and arranges a scraper device having a sonel wire 4 below the front roller 3 and a ring and traveler 5 below. The electrode 6 for applying static electricity from above is provided above the feeding side of the front roller 3 and the annular guide 7 is provided therebelow.

  A preferred example of production of long and short composite spun yarns is to first release the multifilament yarn A wound by the lance 8, apply static electricity to the electrode 6 through the guide 9, and then open the fiber through the annular guide 7. And it supplies to the front roller 3, regulating the supply position. On the other hand, the roving yarn B is supplied to the back roller 1, drafted between the cradle 2 and the front roller 3, and supplied to the front roller 3 as a fleece short fiber bundle B. The opened multifilament yarn A supplied to the front roller 3 and the fleece short fiber bundle B are mixed at the nip point of the front roller 3. At this time, the multifilament has an opening width of the short fiber fleece. The fiber is opened to the same or larger level, and the center of the multifilament is overlapped and mixed with the center of the short fiber fleece. The multifilament and the short fiber fleece that have passed through the front roller 3 are twisted to form a unique yarn structure in which the cross section forms a uniform mixed layer of the filament and the short fiber. 5 is wound on the tube yarn 10. At this time, the conventional long / short composite spun yarn is spun at a twisting factor of at least 100, but in the present invention, it is spun at a twisting factor of 40 to 90. The spun long and short composite spun yarns are generally twisted by twisting two or more long and short composite spun yarns (single yarns) with a twisting factor of 40 to 110, so-called twin yarns or triplet yarns. It is used for manufacture of textiles after making it.

This long / short composite spun yarn was twisted into a twin yarn with a twisting factor of 70, and then a surge was woven with a warp number of 285/10 cm and a weft number of 285/10 cm, and then anti-dyeing was performed. In the process of arranging the woolen fabric after the anti-dyeing, it was finished only by shaving the both sides of the fabric without gas burning, and the fabric pilling, wear strength and texture were evaluated. The results are shown in Table 1.
