It is a photograph which shows the tension state of the high strength yarn whose covering coefficient is inadequate. It is a photograph which shows the relaxation state of the high strength yarn whose covering coefficient is inadequate. It is a photograph after snug-proof evaluation of textiles using the thread shown in Drawing 1-1. It is the photograph after abrasion resistance evaluation of the textile fabric using the thread | yarn shown in FIG. 1-1. It is a photograph in which a covering coefficient shows the tension state of a suitable high strength yarn. It is a photograph showing the relaxed state of a high strength yarn with an appropriate covering coefficient. It is explanatory drawing which shows the size of a lattice-like woven pattern. FIG. 10 is a structural diagram of a dobby weave employed in Example 8. It is explanatory drawing of a loop-like fault.

The woven fabric according to the present invention is a woven fabric having a patterned yarn having a total fineness of 50 to 800 dtex and a ground yarn having a total fineness of 50 to 800 dtex in the warp direction and the weft direction,
At least one of the warp yarn and the weft yarn has a high strength fiber having a tensile strength of 10 cN / dtex or more and an elastic fiber having a total fineness of 33 to 156 dtex, and the content of the high strength fiber is 70 to 95%. Is a high strength yarn that is
Of the warp direction and the weft direction, the ground yarn in the same direction as the direction in which the high-strength yarn is contained is a stretchable synthetic yarn containing synthetic fibers and elastic fibers,
It is characterized in that the following (i) to (iii) are satisfied.
(I) The covering coefficient of the high strength fiber is 10,000 to 21,000.
The fineness ratio represented by (ii) (maximum total fineness of pattern yarn) / (minimum total fineness of ground yarn) is 0.4 to 2.0.
(Iii) The fineness ratio represented by (total fineness of elastic fiber in high strength yarn) / (total fineness of elastic fiber in stretchable synthetic fiber) is 0.8 to 4.0.

Regarding the requirement (i), in the present specification, the covering coefficient of the high tenacity fiber means the number of turns (the number of coverings) of the high tenacity fiber and the covering of the elastic fiber derived from the total fineness of the high tenacity fiber. It is an index that objectively evaluates the degree. The high-strength yarn used as the handle yarn includes a high-strength fiber having poor stretchability and an elastic fiber having excellent stretchability. Therefore, when the covering coefficient is insufficient, the high strength fiber can be made into an elastic fiber having high elasticity when the force is released from the tensioned state shown in FIG. 1-1 to the relaxed state shown in FIG. However, the elastic fiber and the high strength fiber were separated, and the restriction of the high strength fiber was released. When such a yarn is used to make a woven fabric, the high-strength fiber in which the restraint is released is easily broken, causing a problem of fuzzing (see FIGS. 1-3 and 1-4).
Therefore, in the present invention, the above problem has been solved by increasing the covering coefficient of the high-strength fiber as compared with the conventional one. As shown in FIGS. 2-1 and 2-2, when the covering coefficient is appropriate, the restraint of the high strength fiber is maintained even in the relaxed state, and the abrasion is suppressed. The specific method of determining the covering coefficient will be described in detail in the section of the Examples, but the covering coefficient of the high strength fiber is 10000 to 21000, more preferably 11000 to 20500, and still more preferably 11500 to 20000. When the covering coefficient is less than the above range, fuzzing is likely to occur due to rubbing, which leads to deterioration of the abrasion resistance and snag resistance of the fabric (hereinafter, these characteristics may be simply referred to as “scratch resistance”). There is a risk. On the other hand, if the covering coefficient exceeds the above range, the restraining force to the elastic fiber becomes too strong, the high strength yarn becomes rod-like, and it becomes difficult to provide a product having stretchability, which is not preferable. If the upper limit is exceeded, the restraining force is so strong that the high strength yarn tends to be thin. Therefore, the woven fabric becomes coarse density and tends to be transparent, and if the biomechanical density is increased to suppress the transparency, the texture of the woven fabric may become hard or the stretchability may be deteriorated.

  Regarding requirement (ii), in the woven fabric, the fineness ratio represented by (maximum total fineness of handle yarn) / (minimum total fineness of ground yarn) is 0.4 to 2.0, more preferably 0.5 to 0.5. 1.5, more preferably 0.6 to 1.2. It is desirable from the viewpoint of scratch resistance and the like to make the woven fabric as flat as possible and to have a structure with low frictional resistance. For this reason, if the fineness ratio exceeds the upper limit, the pattern yarn is too thick and the frictional force concentrates on the pattern yarn, which is not preferable because it becomes a woven fabric that easily becomes fluffy due to damage to the pattern yarn. On the other hand, if the fineness ratio is less than the lower limit, the ground yarn is too thick and may have a heavy fabric weight or may be an expensive fabric because it uses a thin patterned yarn.

Regarding requirement (iii), the fineness ratio represented by (total fineness of elastic fiber in high strength yarn) / (total fineness of elastic fiber in stretch synthetic fiber) is 0.8 to 4.0, and more Preferably it is 1.0-3.5, More preferably, it is 1.5-3.0. In the high strength yarn, the covering coefficient of the high strength fiber is increased as compared to the conventional one, so the restraint of the elastic fiber is increased and the stretchability of the elastic fiber is reduced. However, it has become possible to solve the above-mentioned problem by slightly increasing the total fineness of the elastic fibers in the handle yarn. If the fineness ratio is less than the lower limit, the stretchability of the high strength yarn is deteriorated, and the patterned yarn is likely to float on the surface of the fabric and be abraded, which is not preferable. If the upper limit is exceeded, the fineness ratio of the high strength yarn and the stretchable synthetic fiber becomes large, and the fabric is finished to a large unevenness, which is not preferable because the abrasion resistance may be deteriorated from the viewpoint of requirement (ii).
In addition, the fineness ratio represented by (total denier of elastic fiber in high strength yarn) / (total denier of elastic fiber in stretchable synthetic fiber) is the ratio of high strength yarn and stretchable synthetic fiber contained in the warp direction, or And the high strength yarn and the stretchable synthetic fiber contained in the latitudinal direction.

  Each component will be described in detail below.

1. Patterned yarn In the present specification, "patterned yarn" is, more specifically, a yarn having a smaller occupied area in the woven fabric than the ground yarn, and is driven into the respective ground yarns in the warp direction and the weft direction at regular intervals. This thread emphasizes the woven pattern. In the present invention, in particular, high strength fibers are used for the purpose of providing a woven fabric excellent in tear strength. However, since the high-strength fiber is hardly dyeable, uniform dyeing of the fabric is difficult. Therefore, in the present invention, it is desirable that the above-mentioned patterned yarn contains a high strength fiber by utilizing this characteristic. If the patterned yarn contains high strength fibers, only the patterned yarn can be dyed after dyeing the fabric, and the woven pattern can be emphasized. A lattice-like woven pattern is formed on the woven fabric by driving the patterned yarn into the ground yarn at regular intervals in the warp and weft directions.

  The total fineness of the handle yarn is 50 to 800 dtex, more preferably 80 to 600 dtex, and still more preferably 100 to 500 dtex. Within the above range, a lightweight and highly productive fabric can be obtained. In this specification, it is assumed that the twist shrinkage is not included in the evaluation of the total fineness.

<High strength yarn>
In the present invention, at least one of the warp yarn and the weft yarn is a high strength fiber having a tensile strength of 10 cN / dtex or more and an elastic fiber having a total fineness of 33 to 156 dtex, and the content of the high strength fiber is It is a high tenacity yarn that is 70 to 95%. The high-strength yarn is included in the warp direction, the weft direction, or both the warp direction and the weft direction of the fabric in consideration of the direction in which stretchability is desired.

  The tensile strength of the high strength fiber is preferably 13 cN / dtex or more, more preferably 16 cN / dtex or more, still more preferably 20 cN / dtex or more, preferably 40 cN / dtex or less, more preferably 38 cN / dtex or less, still more preferably. Is 35 cN / dtex or less. If the tensile strength is less than the above range, the tear strength of the fabric is unfavorably reduced. The tensile strength of the high strength fiber is measured based on, for example, JIS L 1013 8.5.1: 2010.

  As high-strength fibers, high-strength polyethylene fibers represented by Toyobo's "Izanas (registered trademark)" and "Tunuga (registered trademark)"; Teijin's "Technora (registered trademark)", Toray DuPont's " Para-aramid fibers represented by "Kevlar (registered trademark)"; High-strength polyarylate fibers represented by "Bectran (registered trademark)" manufactured by Kuraray; Poly represented by "Zyron (registered trademark)" manufactured by Toyobo Co., Ltd. Examples thereof include paraphenylene benzoxazole (PBO) fiber; polyvinyl alcohol fiber represented by “Kuraron (registered trademark) KII” manufactured by Kuraray Co., Ltd., and the like. As the high strength fiber, a lightweight high strength polyethylene fiber is preferable.

  The breaking elongation of the high strength fiber is not particularly limited, but is preferably 0.1 to 7.5%, more preferably 0.5 to 7.0%, and still more preferably 1.0 to 6.4%. Adjusting the cut elongation to the above range is preferable because a fabric having high tear strength is provided. The cut elongation of the high strength fiber is measured based on, for example, JIS L 1013 8.5.1: 2010.

  The high strength fiber may be either monofilament or multifilament. A multifilament is preferably used as the high strength fiber in order to impart high flexibility to the yarn while making the high strength yarn high strength.

The total fineness of the high strength fiber is preferably 20 to 700 dtex, more preferably 50 to 550 dtex, and still more preferably 90 to 440 dtex. If the total fineness is in the above-mentioned range, a cheap, light-weight material can be obtained, and yarn breakage can be suppressed, so that a woven fabric excellent in abrasion resistance is provided.
The single yarn fineness of the high strength fiber is preferably 0.3 to 3.0 dtex, more preferably 0.5 to 2.5 dtex, and still more preferably 0.8 to 2.0 dtex. If the single yarn fineness is in the above range, a fabric having a soft feeling and less fuzz can be obtained.

  The high-strength fiber may be an original yarn. The base yarn is a raw yarn colored by mixing colorants such as a pigment and a dye at the stage of the stock solution before spinning. The color of the high-strength fiber is not particularly limited, and is appropriately adjusted depending on the application, such as black or amber color. The high-strength fiber containing the colorant is preferably an original yarn containing 5% by weight or less (preferably 0.01% by weight or more) of pigment.

  The high strength fiber may be either a raw yarn or a crimped yarn, and from the viewpoint of enhancing the stretchability, a crimped yarn, particularly a false-twisted yarn is preferred. On the other hand, crimped yarn (especially false twisted yarn) may have problems of strength reduction and fuzzing due to crimp processing, so from the viewpoint of taking advantage of the strength characteristics of high strength fibers, high strength fibers are raw yarns ( Crimped yarns) are preferred.

  The high-strength fiber may be either non-twisted yarn or twisted yarn, but the scratch resistance can be increased even with a small covering coefficient, and further, the elasticity of the elastic fiber is not impaired by reducing the covering coefficient, and it is rich in elasticity. The high tenacity fibers are preferably twisted yarns because of the advantage that a woven fabric is obtained.

  When the high strength fiber is a twisted yarn, the twist coefficient of the high strength fiber is preferably 1000 to 8000, more preferably 1500 to 7000, and still more preferably 2000 to 6000. If it is in the said range, it will become the high tenacity thread | yarn with favorable covering property, improving the bundling property of a high tenacity fiber, and abrasion resistance will become favorable. The method for obtaining the twist coefficient of the high-strength fiber will be described in detail in the Examples section. The twisting direction of the high strength fiber may be either the S direction or the Z direction.

  In the high-strength yarn, the content of the high-strength fiber is 70 to 98%, more preferably 75 to 96%, and still more preferably 78 to 98% in terms of fineness ratio (total fineness of high-strength fiber / total fineness of high-strength yarn). It is 95%. When the content of the high-strength fiber is within the above range, a woven fabric having good quality, fastness, scratch resistance, low cost and excellent tear strength can be obtained.

On the other hand, high strength yarns contain elastic fibers. The presence of the elastic fiber makes it possible to impart stretchability to the woven fabric. Here, the elastic fiber refers to a fiber having a higher elasticity than a general fiber, and specifically, a synthetic fiber having a cutting elongation of 400 to 850% (more preferably 750% or less) is preferable. The tensile strength of the elastic fiber is preferably 0.7 to 1.3 cN / dtex (more preferably 0.8 to 1.2 cN / dtex), and the recovery rate at 200% elongation is preferably 80% or more. is there.
In addition, the tensile strength and cutting elongation of an elastic fiber are measured based on JISL1013 8.5.1: 2010, for example. Furthermore, the recovery rate at 200% elongation is 200% in constant speed extension type according to JIS L1013 8.5.1: 2010, and then returned at the same speed as that at extension, and the stress becomes 0. Is calculated and calculated by (200−A) × 100/200.

  The fiber constituting the elastic fiber is not particularly limited, and various conjugate fibers such as polyurethane fiber, polyether-based polyurethane fiber, polybutylene terephthalate (PBT) fiber, polytrimethylene terephthalate fiber (PTT), polyester and / or nylon fiber, etc. However, polyurethane fibers are preferred because sufficient stretchability and recoverability are easily imparted. The polyurethane fiber may contain an antibacterial deodorant, an ultraviolet absorber / reflector, a hygroscopic exothermic agent and the like depending on the application. Further, the elastic fiber may be heat-fusible in order to reduce separation from the high-strength fiber. Examples of the heat-fusible elastic fiber include “Mobilon (registered trademark) RL” manufactured by Nisshinbo Textile Co., Ltd.

  The elastic fiber may be monofilament or multifilament. The total fineness of the elastic fiber is 33 to 156 dtex, more preferably 44 to 156 dtex, still more preferably 44 to 120 dtex. If it exceeds the above range, the stretchability is too strong, and the elastic fibers are likely to be exposed on the surface of the fabric, which may cause ultraviolet deterioration. Below the above range, the stretchability of the fabric becomes insufficient.

  In the high-strength yarn, the content of the elastic fiber is preferably a fineness ratio (total fineness of the elastic fiber / total fineness of the high-strength yarn), preferably 5 to 60%, more preferably 8 to 60%. If the content rate of the said elastic fiber is in the said range, isolation | separation of a core part and a sheath part can be suppressed, and the textile fabric excellent in abrasion resistance is obtained.

  The content of the high strength fiber and the elastic fiber in the high strength yarn is a fineness ratio (total fineness of the high strength fiber: total fineness of the elastic fiber), preferably 50:50 to 99: 1, more preferably 60:40 to 95: 5, more preferably 65:35 to 90:10. If the content rate of a high strength fiber and an elastic fiber exists in the said range, the textile fabric which has a stretching property and high intensity | strength will be provided.

  The high strength yarn is preferably substantially composed of high strength fibers having a tensile strength of 10 cN / dtex or more and elastic fibers having a total fineness of 33 to 156 dtex. The mixing ratio of the high strength fiber and the elastic fiber is preferably at least 80% by weight, more preferably at least 90% by weight, still more preferably at least 95% by weight, and particularly preferably 99% by weight in 100% by weight of the high strength yarn. % Or more.

  A covering yarn having a core-sheath structure comprising, for example, the elastic fiber as a core and the high strength fiber as a sheath; a high twisting yarn composed of the high strength fiber and the elastic fiber; An air entangled yarn composed of strong fibers and the elastic fiber is preferable, and a covering yarn is more preferable because of good abrasion resistance.

  When the high tenacity yarn is a covering yarn, the high tenacity yarn may be either a single covering yarn (SCY) or a double covering yarn (DCY). However, in order to reduce unevenness on the fabric surface and improve the scratch resistance, the single covering yarn is used. Yarn is desirable. Particularly in DCY, a high strength fiber directly wound on the elastic fiber (hereinafter referred to as "inner high strength fiber") and a high strength further wound around the elastic fiber covered by the inner high strength fiber. The fineness ratio or covering coefficient ratio of the fibers (hereinafter referred to as “outer high-strength fibers”) may be appropriately adjusted.

  For example, the total fineness ratio of the inner high strength fiber and the outer high strength fiber (inner high strength fiber / outer high strength fiber) is preferably 0.8 to 1.2, more preferably 0.9 to 1.1, Preferably it is 0.95 to 1.05. If it is in the said range, the unevenness | corrugation on the surface of covering yarn can be decreased and the textile fabric excellent in abrasion resistance is provided.

  Moreover, the covering coefficient ratio (inner high strength fiber / outer high strength fiber) of the inner high strength fiber and the outer high strength fiber is preferably 0.8 to 1.2, more preferably 0.9 to 1.1, Preferably it is 0.95 to 1.05. If it is in the said range, the unevenness | corrugation on the surface of covering yarn can be decreased and the textile fabric excellent in abrasion resistance is provided.

When the high strength fiber is a twisted yarn, the twisting direction of the high strength fiber and the covering direction of the high strength fiber in the covering yarn may be the same or opposite. If the same, it is preferable because the high-tensile strength fiber is more concentrated and the abrasion resistance of the fabric is improved.
Note that “the twist direction of the high strength fiber and the covering direction of the high strength fiber in the covering yarn are the same” means, for example, when the twist direction is “S”, the covering direction is “S”, “The twist direction of high strength fibers and the covering direction of high strength fibers in covering yarn are opposite to each other” means, for example, when the twist direction is “S”, the covering direction is “Z”.

  The high-strength yarn can be produced by a covering machine, a twisting machine (for example, a double twister machine) or the like. When the high-strength yarn is a covering yarn, for example, using a covering machine, the elastic fiber is supplied while drafting in the draft zone, and the elastic fiber is passed through the middle of the hollow spindle, and the high-strength fiber installed on the hollow spindle is used. The high-strength fiber may be wound around the elastic fiber by rotating the bobbin around which the wire is wound. The draft rate of the elastic fiber is not particularly limited, and is preferably 2.0 to 4.0 times, more preferably 2.2 to 3.5 times. If it is in the said range, the thread | yarn with the high recoverability after expansion | extension will be obtained. In the draft zone, an apron roller can be used.

  The manufactured high strength yarn may be subjected to aging for sunal suppression, a vacuum steam set (for example, at 60 to 70 ° C. for 20 to 40 minutes), and the like, as necessary.

<Pattern yarn other than high strength yarn>
In the present invention, any synthetic fiber yarn except high-strength yarn can be used as long as high-strength yarn is included as a patterned yarn of a woven fabric. Raw silk can also be used as synthetic fiber yarn excluding high strength yarn, but in view of abrasion resistance, a gathered yarn such as twisting yarn, covering yarn, entangled yarn and the like is preferable. Although the material constituting the yarn is not particularly limited, it is preferable that the yarn contains the high strength fiber described above from the viewpoint of improving the tear strength of the fabric.

2. In the present specification, the "ground yarn" more specifically refers to a yarn that constitutes the ground of the fabric in each of the warp direction and the weft direction. The ratio represented by (the number of handle yarns) / (the number of base yarns) in one lattice-like woven pattern (specifically, one complete structure) is preferably 1: 1 in each of the warp direction and the weft direction. To 1:60, more preferably 1: 3 to 1:20. If the ratio of the handle yarn increases, the woven fabric becomes expensive. Therefore, if it is within the above range, the woven fabric is relatively inexpensive and has sufficient tear strength.

  The total fineness of the ground yarn is 50 to 800 dtex, more preferably 80 to 600 dtex, still more preferably 100 to 500 dtex. If the above range is exceeded, it is not preferable because lightweight woven fabrics are difficult to obtain.

<Stretchable synthetic fiber>
In order to enhance the stretchability of the woven fabric, in the present invention, the base yarn in the same direction as the direction in which the high strength yarn is included among the warp direction and the weft direction is a stretchable synthetic fiber including synthetic fibers and elastic fibers. By aligning the direction of the high-strength yarn of the pattern yarn and the stretchable synthetic yarn of the ground yarn, the stretchability of the fabric can be further improved. Moreover, an intensity | strength improves because an elastic synthetic fiber contains a synthetic fiber.

  The elastic fiber contained in the stretchable synthetic fiber is preferably, for example, a synthetic fiber having a breaking elongation of 400% to 850% (more preferably 750% or less). The tensile strength of the elastic fiber is preferably 0.7 to 1.3 cN / dtex (more preferably 0.8 to 1.2 cN / dtex), and the recovery rate at 200% elongation is preferably 80% or more. is there. As the fibers constituting the elastic fibers, exemplified are the same as the elastic fibers contained in the high strength yarn, and polyurethane fibers are preferable because they can easily impart sufficient stretchability and recovery.

The elastic fibers in the stretchable synthetic fiber may be either monofilaments or multifilaments.
The total fineness of the elastic fiber is 33 to 156 dtex, more preferably 44 to 156 dtex, and still more preferably 44 to 120 dtex. If the above range is exceeded, the elasticity is so strong that the elastic fibers are likely to be exposed on the surface of the fabric, which may cause the deterioration of ultraviolet rays. Below the above range, the stretchability of the fabric becomes insufficient.

  The elastic fiber content in the stretchable synthetic yarn is preferably a fineness ratio (total fineness of the elastic fiber / total fineness of the stretchable synthetic yarn), preferably 5 to 45%, more preferably 8 to 40%. is there. If it is in the said range, the textile fabric excellent in the elasticity is obtained.

  The synthetic fiber contained in the stretchable synthetic yarn is preferably a multifilament. The synthetic fibers are preferably polyamide fibers such as nylon 6 fibers and nylon 66 fibers; polyester fibers such as polyethylene terephthalate fibers and polybutylene terephthalate fibers; etc., and these fibers are used alone or in combination of two or more. Among these, polyamide fibers that are easily dyed and easily obtain abrasion resistance are preferable, and nylon 6 fibers or nylon 66 fibers are more preferable. In particular, when high strength polyethylene fiber is selected as the high strength fiber, nylon 6 fiber or normal pressure cationic dyeable polyester fiber is preferable because temperature limitation may occur during the dyeing process.

  The relative viscosity of the resin constituting the polyamide fiber is preferably 2.5 to 4.5, more preferably 2.7 to 4.2, and still more preferably 2.9 to 4.0.

  The synthetic fiber may contain a coloring agent such as a pigment (carbon etc.) or a dye, an antibacterial deodorant, an ultraviolet absorber / reflecting agent, a heat storage agent, etc. according to the use.

  The cross-sectional shape of the synthetic fiber may be either a round cross section or a modified cross section. Examples of the atypical cross section include a polygonal cross section such as a triangle; a multi-lobal cross section such as a Y-shape, a cross, a six leaf, and an eight leaf; and the like. The synthetic fiber may be solid or hollow.

  The single yarn fineness of the synthetic fiber is preferably 2.8 to 11 dtex, more preferably 3.0 to 10.5 dtex, and still more preferably 4.5 to 10 dtex. The total fineness of the synthetic fiber is preferably 20 to 500 dtex, more preferably 100 to 300 dtex. If it is in the said range, it will become the textile which is excellent in abrasion resistance and has a soft touch.

  The synthetic fiber may be either a raw yarn or a crimped yarn, and from the viewpoint of enhancing the stretchability, a crimped yarn, particularly a false-twisted yarn is preferred. The method of false twisting is not particularly limited, and general methods such as a friction type and a PIN type can be adopted. In addition, fibers to be subjected to false twisting may be appropriately selected depending on applications, such as POY (Partially Oriented Yarn) and FDY (Fully Draw Yarn).

  The stretch recovery rate of the synthetic fiber is, for example, preferably 10 to 40%, more preferably 12 to 37%, and still more preferably 15 to 35%. In addition, the expansion-contraction restoration rate of a synthetic fiber is measured based on JISL10138.12: 2010, for example.

  The tensile strength of the synthetic fiber is preferably 3.7 to 6.5 cN / dtex, more preferably 4.0 to 6.0 cN / dtex. Within the above range, single yarn breakage can be prevented, and a woven fabric with good scratch resistance can be obtained. The tensile strength of the synthetic fiber is measured, for example, based on JIS L 1013 8.5.1: 2010.

  The cut elongation of the synthetic fiber is preferably 20 to 38%, more preferably 23 to 32%. If it is in the said range, there are few fuzz and the textile fabric with favorable abrasion resistance is obtained. The cut elongation of the synthetic fiber is measured based on, for example, JIS L 1013 8.5.1: 2010.

Synthetic fibers, like high-strength fibers, may be either non-twisted yarns or twisted yarns, but with a small covering coefficient can improve scratch resistance, and by reducing the covering coefficient, the elasticity of the elastic fibers is not impaired. The synthetic fiber is preferably a twisted yarn because of advantages such as obtaining a highly elastic woven fabric.
When the synthetic fiber is a twisted yarn, the twist coefficient of the synthetic fiber is preferably 1000 to 12000, more preferably 1500 to 7500, and still more preferably 2000 to 6000. If it is in the said range, it will become an elastic synthetic fiber with a favorable coating property, improving abrasion resistance, improving the bundling property of a synthetic fiber. Further, the twisting direction of the synthetic fiber may be either the S direction or the Z direction.

  The elastic synthetic fiber is, for example, a covering yarn having a core-sheath structure in which the elastic fiber is used as a core and the synthetic fiber is used as a sheath; a synthetic yarn comprising the synthetic fiber and the elastic fiber; Air-entangled yarn composed of the above-mentioned elastic fiber and the like; etc. is preferable, and a covering yarn or a composite yarn obtained by air-entangling the above-mentioned elastic fiber with the above-mentioned synthetic fiber is more preferable since scratch resistance is good. .

  The covering coefficient of the synthetic fiber is preferably 10,000 to 21,000, more preferably 11000 to 20500, and still more preferably 11500 to 20000. If it is within the above range, the elastic fiber is not restrained too much, so it becomes a woven fabric excellent in stretchability, and since the elastic fiber can be sufficiently covered with a synthetic fiber, it becomes a woven fabric excellent in abrasion resistance. A specific method for obtaining the covering coefficient will be described in detail in the section of the embodiment.

  When the stretchable synthetic yarn is a covering yarn, the stretchable synthetic yarn may be either a single covering yarn (SCY) or a double covering yarn (DCY). However, in order to reduce unevenness on the fabric surface and improve scratch resistance, Single covering yarn is desirable.

When the synthetic fiber is a twisted yarn, the twisting direction of the synthetic fiber and the covering direction of the synthetic fiber in the covering yarn may be the same or opposite. It is preferable that it is the same, since the synthetic property of the synthetic fiber is further enhanced and the abrasion resistance of the fabric is improved.
Similarly to the above, "the same direction as the synthetic fiber twisting direction and the covering direction of the synthetic fiber in the covering yarn is the same" means that the covering direction is "S" when the twisting direction is "S", for example, “The twisting direction of the synthetic fiber and the covering direction of the synthetic fiber in the covering yarn are opposite to each other” means, for example, that the covering direction is “Z” when the twisting direction is “S”.

  The air entanglement degree is preferably 5 to 120, more preferably 15 to 105, and still more preferably 25 to 95 / m.

The stretchable synthetic fiber can be manufactured by a covering machine, a twisting machine (for example, a double twister machine) or the like.
When the stretchable synthetic yarn is a covering yarn, for example, using a covering machine, the elastic fiber is supplied while being drafted in a draft zone, and the elastic fiber is passed through the middle of the hollow spindle, and the synthetic fiber is installed on the hollow spindle. The synthetic fiber may be wound around the elastic fiber to manufacture by rotating the wound bobbin.
Further, for example, a synthetic elastic fiber and a drafted elastic fiber are aligned and supplied to a known interlacer, and the synthetic fiber and the elastic fiber are air-entangled with high pressure air, and then applied with a twisting machine or the like. It can also be manufactured by twisting.
The draft rate of the elastic fiber is not particularly limited in any method, and is preferably 2.0 to 4.0 times, more preferably 2.2 to 3.5 times. If it is in the said range, the recovery | restoration raw | good thread | yarn after an expansion | extension will be obtained. In the draft zone, it is also possible to use an apron roller.

  The manufactured stretchable synthetic fiber may be subjected to aging for suppression of sunal, a vacuum steam set (for example, at 60 to 70 ° C. for 20 to 40 minutes), and the like, as necessary.

<Ground yarn other than elastic synthetic yarn>
In the present invention, not only the stretchable synthetic yarn but also any yarn other than the stretchable synthetic yarn can be used as the ground yarn. Raw silk can also be used as the stretchable synthetic fiber, but from the viewpoint of abrasion resistance, a combined yarn such as twisting yarn, covering yarn, entangled yarn, etc. is preferable. Although the material which comprises the said thread | yarn is not specifically limited, It is desirable for the said thread | yarn to contain the synthetic fiber mentioned above from a viewpoint of improving the tearing strength of a textile fabric.

In Comparative Example 1, since the covering coefficient was not sufficient, the abrasion resistance was deteriorated. In Comparative Example 2, since the covering coefficient exceeded the appropriate value, the fabric became a hard feeling. Further, the polyurethane fiber in the SCY yarn was strongly restrained by the sheath yarn and the stretchability became weak, and the shrinkage at the time of the dyeing process became insufficient, resulting in a woven fabric having a coarse-density sheer. In Comparative Example 3, since the high strength fiber was not used, the tear strength of the woven fabric was insufficient.

Comparative example 3
A high strength polyethylene fiber in the patterned yarns (1) and (3) was changed to a nylon 6 crimped yarn shown in the table, and the other fabric was obtained in the same manner as in Example 1 under the conditions shown in the table.

In Comparative Example 5, since the covering coefficient exceeds the appropriate value, it becomes a woven fabric having a hard feeling, and similarly to Comparative Example 2, the stretching force of the SCY yarn becomes weak, and the shrinkage at the time of dyeing becomes insufficient. As a result, it became a woven fabric with a coarse sheen.

In Comparative Example 6, since the fineness ratio represented by (maximum total fineness of the handle yarn) / (minimum total fineness of the ground yarn) exceeds the appropriate value, the unevenness of the fabric becomes large and the scratch resistance is deteriorated. .

Comparative Example 7
A woven fabric was obtained in the same manner as in Example 1 except that the total fineness of the polyurethane fibers in the patterned yarns (1) and (3) was changed and the other conditions were as shown in the table. In Comparative Example 7, since the fineness ratio represented by (total fineness of elastic fiber in high strength yarn) / (total fineness of elastic fiber in elastic synthetic fiber) is lower than an appropriate value, the expansion and contraction of high strength yarn The property deteriorated, and the patterned yarn floated on the surface of the fabric and was easily rubbed off. In addition, the processing shrinkage of the high strength yarn was deteriorated, the density became coarse, and the total fineness was thin, so that the shedding occurred particularly at the patterned yarn location.
