[0025] [Figure 1] FIG. [Figure 2] FIG. [Figure 3] FIG. [Figure 4] FIG. 2 is a perspective view of (a) a large diameter mall-shaped thread and (b) a small diameter mall-shaped thread. [Figure 5] (a) A perspective view of a mesh tube outer filament, (b) a cylindrical outer periphery, and (c) a bundle of single fibers. DETAILED DESCRIPTION OF THE INVENTION

[0026] [1] An embodiment of the present invention will be described with reference to the drawings.

[0027] All of the drawings are of wiping cloths made from the fabric of the present invention.

[0028] (1) The fabric C constituting the wiping cloth T in this example is a plain weave fabric C made of warp and weft threads. The ends of the fabric C are folded back and sewn together. This wiping cloth T can be used as a hand towel, but can also be used for other purposes.

[0029] As the warp threads, large diameter mall-shaped threads Ma with an outer diameter of 10 mm and small diameter mall-shaped threads Mb with an outer diameter of 5 mm are alternately used, and as the weft threads, mesh tube outer peripheral threads N with an outer diameter of 7.5 mm are used.

[0030] In the thickness direction of this woven fabric C, the outer peripheral portion of the large diameter mall-shaped thread Ma constitutes one surface portion and the other surface portion of the woven fabric C (the outermost portions in one and the other thickness directions, respectively, i.e., the outermost front portion F and the outermost back portion B), and the outer peripheral portion of the mesh tube outer thread N and the outer peripheral portion of the small diameter mall-shaped thread Mb are both located inward from one surface portion and the other surface portion of the woven fabric C (the outermost portions in one and the other thickness directions, respectively).

[0031] (2) Molded thread

[0032] (2-1) Both the large diameter mall-shaped yarn Ma and the small diameter mall-shaped yarn Mb have numerous non-absorbent or low-absorbent polyester fiber filaments held in a tow state transverse to the core yarn as decorative yarn D. These filaments are approximately 0.8 denier and have an average cross-sectional flatness of 0.7.

[0033] These numerous single fibers are not twisted together, and are densely packed circumferentially, radially arranged approximately in the radial direction around the core thread, with the density increasing toward the inside and the density increasing toward the axial direction. Water absorption occurs from the outer periphery of the mall-shaped thread body toward the inside due to capillary action.

[0034] (2-2) The large-diameter mall-shaped thread Ma and the small-diameter mall-shaped thread Mb both have an approximately cylindrical shape, but (a) the large-diameter mall-shaped thread Ma and (b) the small-diameter mall-shaped thread Mb shown in Figure 4 both retain the shape they had when used as warp threads in this woven fabric C.

[0035] (2-3) The pitch, which is the distance between the center lines of adjacent large-diameter mall-shaped threads Ma and small-diameter mall-shaped threads Mb as warp threads, is approximately 4.5 mm, which is 0.3 times the sum of the outer diameters of the large-diameter mall-shaped threads Ma and the small-diameter mall-shaped threads Mb, which is approximately 15 mm.

[0036] (3) Mesh tube outer thread

[0037] (3-1) The mesh cylindrical outer yarn N is made of a non-absorbent or low-absorbent material and has a cylindrical outer circumferential portion P formed in a mesh shape, in which a large number of non-absorbent or low-absorbent polyester fiber filament bundles U (tows) are housed along the axis of the cylindrical outer circumferential portion P. The filament bundles U are in a state where several parallel bundles are continuous in the axial direction together with the cylindrical outer circumferential portion P. The monofilaments are approximately 5 denier, and the average flatness of the cross section is approximately 0.3.

[0038] (3-2) The cylindrical outer circumferential portion P is formed into a cylindrical shape by a knitted mesh structure made of twisted yarns of polyester-based fibers as non-absorbent or low-absorbent monofilaments. The monofilaments have a fineness of about 2 denier and an average flatness of the cross section of about 0.3.

[0039] (3-3) The mesh tube outer peripheral thread N has an approximately cylindrical shape, but (a) the mesh tube outer peripheral thread N, (b) the cylindrical outer peripheral portion P, and (c) the bundle of single fibers U shown in Figure 5 all retain the shapes used as weft yarns in this woven fabric C.

[0040] (3-4) The pitch, which is the distance between the center lines of adjacent weft yarns N, is approximately 9 mm, which is 0.6 times the sum of the outer diameters of adjacent weft yarns N, which is approximately 15 mm.

[0041] (3-5) The mesh cylindrical outer yarn N is relatively easy to absorb and discharge water or other water-based liquids through the cylindrical outer periphery P into the bundle of single fibers U within the cylindrical outer periphery P.

[0042] (3-5) The outer diameter of the mesh tube outer thread N, which is the weft thread, is more easily reduced than the outer diameter of at least the large-diameter mall-shaped thread Ma, which is the warp thread, so this wiping cloth T has good flexibility and adaptability to the unevenness of the object to be wiped.

[0043] In addition, the large diameter mole-shaped threads Ma and small diameter mole-shaped threads Mb serving as warp threads absorb water from the outer periphery inward due to capillary action, and the mesh tube outer threads N serving as weft threads absorb and discharge water relatively easily through the cylindrical outer periphery P into the bundles of single fibers U within the cylindrical outer periphery P, thereby achieving good water absorption and dewatering properties overall.

[0044] [2] The embodiments of the present invention will be further described, including embodiments other than those described above.

[0045] (1) The woven fabric of the present invention is composed of warp threads and weft threads, one of which is a molle-shaped thread body and the other is a mesh tube outer periphery thread body.

[0046] The wiping cloth of the present invention comprises the woven fabric of the present invention.

[0047] In the thickness direction of the woven fabric of the present invention, the outer peripheral portion of the mall-shaped thread body constitutes one surface portion and the other surface portion of the woven fabric (the outermost portions in one and the other thickness directions, respectively), and the outer peripheral portion of the mesh tube outer thread body is located inward from the one surface portion and the other surface portion of the woven fabric.

[0048] When two or more types of molle-shaped threads with different outer diameters (natural outer diameters) are used as the warp or weft threads (for example, when two types are used alternately as the warp threads [or weft threads]), the outer periphery of the molle-shaped thread with the largest outer diameter (natural outer diameter) can constitute one surface portion and the other surface portion of the woven fabric. Note that the natural outer diameter of a molle-shaped thread or a mesh tube outer peripheral thread refers to the outer diameter when not in an unusual state, such as when subjected to a particular external force. In this specification, the "outer diameter" of a molle-shaped thread or a mesh tube outer peripheral thread means the "natural outer diameter" unless otherwise specified.

[0049] The weaving method of the woven fabric of the present invention can be, for example, plain weave, twill weave, etc., but is not limited to these.

[0050] The woven fabric of the present invention can be used for applications where water absorbency is required or desired, such as wipes for hands, faces, bodies, etc., as well as for carpets, clothing, etc.

[0051] (2) Molded thread

[0052] (2-1) A molle-like yarn body has a core yarn and a large number of non-absorbent or low-absorbent single fibers as decorative yarns. These numerous single fibers are densely packed in the circumferential direction, radially arranged approximately in the radial direction around the core yarn, with the density increasing toward the inside and the density increasing toward the axial direction. The absorbency of the molle-like yarn body acts from the outer periphery toward the inside by capillary action.

[0053] (2-2) Non-absorbent or low-absorbent single fibers

[0054] The non-water-absorbent or low-water-absorbent single fibers may have a water absorption rate of, for example, 3% or less at 20°C and a relative humidity of 65%. Preferably, the water absorption rate is 2% or less, and more preferably 1% or less, at 20°C and a relative humidity of 65%. Such single fibers may be made of filaments of polyester fibers, polypropylene fibers, polyethylene fibers, polyamide fibers, etc. (preferably polyester fibers, polypropylene fibers, or polyethylene fibers). If necessary, all or part of the single fibers used as decorative threads may be subjected to a hydrophilization treatment using various surfactants, etc.

[0055] (2-3) Single fiber fineness, length, etc.

[0056] The fineness of the single fiber used as the decorative thread is, for example, 0.03 to 5 denier, preferably 0.03 to 3 denier, more preferably 0.03 to 2 denier, and even more preferably 0.03 to 1.5 denier, and can also be 1.2 denier or less, 1 denier or less, or 0.8 denier or less.

[0057] The length of the filament as the decorative thread can be, for example, 3 to 40 mm, but is not limited to this. It is also desirable that the length of the decorative thread is constant, but is not limited to this.

[0058] (2-4) Water absorption of the strip-shaped yarn The single fibers used as decorative threads in the above-mentioned mall-shaped thread body, i.e., the numerous single fibers that are densely packed circumferentially in a radial pattern around the core thread, with the density increasing toward the inside and packed closely together in the axial direction, are non-absorbent or have low water absorption, so that water absorption force acts from the outer periphery of the mall-shaped thread body toward the inside due to capillary action.

[0059] This allows the outer periphery of the absorbed woven fabric to rapidly absorb a relatively large amount of water inward, and the moisture content of the outer periphery of the woven fabric is low due to capillary action. Moreover, since the outer periphery is formed by the tips of non-absorbent or low-absorbent single fibers, the area occupied by the fibers is relatively small, and the fibers themselves remain non-wet. Therefore, the outer periphery, once water is absorbed, is less likely to feel sticky.

[0060] It is desirable that the filaments used as decorative yarns are basically independent of each other except for the portions held by the core yarn. The decorative yarns are preferably filaments that are not twisted together (single filaments that are not twisted to form a thread or bundled by twisting) (for example, tow can be used as decorative yarns), but this is not limitative.

[0061] The decorative yarn may be, for example, approximately 10,000 to 250,000 single fibers per 1 cm of axial length of the mall-shaped yarn body, closely spaced radially from the axis and closely spaced in the axial direction.

[0062] The average cross-sectional flatness of the numerous single fibers serving as numerous decorative threads in the woven fabric can be, for example, 0.5 or more (e.g., 0.5 to 0.9). It is preferably 0.55 or more, more preferably 0.6 or more. When the average cross-sectional flatness of the numerous non-absorbent or low-absorbent single fibers constituting the numerous decorative threads in the woven fabric is 0.5 or more, the woven fabric has significantly higher water absorption than woven fabrics having non-absorbent or low-absorbent single fibers serving as decorative threads with a low flatness. The flatness f means f = (ab) / a, where a is the maximum dimension of the cross section and b is the dimension perpendicular to the maximum dimension. The cross-sectional shape, such as the flatness of the single fibers, can be substantially the same in any cross section, but is not necessarily limited to this.

[0063] (2-5) Holding decorative threads, etc.

[0064] The holding of the multiple decorative threads in the mall-shaped yarn body can be such that the multiple decorative threads are held in the middle of the core thread so as to be horizontal to the core thread.

[0065] It is desirable that the intermediate portion of the decorative yarn held by the core yarn is at a fixed position in the length direction of the decorative yarn, particularly at the center position.

[0066] When the decorative yarn is oriented horizontally relative to the core yarn, it means that the longitudinal direction of the decorative yarn held by the core yarn forms an angle of approximately 60 to 90 degrees with respect to the longitudinal direction of the core yarn, preferably 70 to 90 degrees, and more preferably 80 to 90 degrees or 85 to 90 degrees.

[0067] The decorative thread can be held relative to the core thread by, for example, the force of clamping it between multiple core threads (for example, between multiple core threads that are twisted together), by the adhesive force of a fixing substance such as adhesion or fusion to one or preferably two or more core threads, or a combination of both (a combination of the force of clamping it between multiple core threads and the adhesive force of a fixing substance).

[0068] When the holding is performed by the adhesive force of an adhesive substance, for example, a heat-sealable yarn can be used as the core yarn, and the core yarn can be fused by heat treatment.

[0069] The multiple decorative yarns can be held evenly or at intervals along the length of the core yarn. Holding at intervals can include holding a group of multiple decorative yarns at regular intervals or at variable intervals along the length of the core yarn. When decorative yarns are held between multiple core yarns that are twisted together, the decorative yarns can be held at regular intervals according to the number of twists, for example.

[0070] Examples of the core yarn include, but are not limited to, monofilament yarn, spun yarn, or multifilament twisted yarn having a density of 10 to 300 denier. The heat-sealable yarn may also be used. Examples of the material for the core yarn include, but are not limited to, polyester fiber, polypropylene fiber, polyethylene fiber, and polyamide fiber.

[0071] (2-6) Morphology of the Mole-like Threads

[0072] The mohair thread may have a generally cylindrical shape. The mohair thread may also be formed by twisting together multiple (e.g., two) mohair yarns around the core yarn of each mohair yarn, with the twisted part forming a single mohair thread.

[0073] The outer peripheral surface of the approximately cylindrical shape of the mall-shaped yarn body can be formed by the tip of a single fiber (including a tow) that is a decorative yarn.

[0074] The outer diameter of the molle-like thread may be, for example, 4 to 40 mm, and is preferably substantially constant. The natural diameter of the molle-like thread is preferably 6 to 25 mm, more preferably 8 to 20 mm.

[0075] (2-7) Pitch of the molle-like thread

[0076] The pitch of the molle thread can be, for example, 0.2 to 0.7 times the sum of the outer diameters of adjacent molle threads (adjacent molle threads constituting the warp threads in the case of the warp pitch, and adjacent molle threads constituting the weft threads in the case of the weft pitch), and preferably, for example, 0.25 to 0.4 times the sum of the outer diameters. This is almost the same whether molle threads with the same outer diameter are used or whether two or more types with different outer diameters are used, for example, adjacent to each other, are used.

[0077] Pitch refers to the distance between the center lines of adjacent warp threads or adjacent weft threads in a plane along which the woven fabric runs (for example, the horizontal distance between the center lines of adjacent warp threads or the horizontal distance between the center lines of adjacent weft threads when the woven fabric runs along a horizontal plane). If the pitch of the warp or weft threads is less than 0.5 times the sum of the outer diameters of the adjacent molle-shaped threads, for example, 0.4 times or less, the adjacent warp threads that are the molle-shaped threads that make up the warp threads, or the adjacent weft threads that are the molle-shaped threads that make up the weft threads, may be in a state where their outer peripheries are pressed against each other.

[0078] (3) Mesh tube outer thread

[0079] (3-1) The mesh tube outer yarn body is made of a non-absorbent or low-absorbent material and is formed by accommodating a large number of bundles of non-absorbent or low-absorbent single fibers in a mesh-like cylindrical outer periphery along the axis of the cylindrical outer periphery.

[0080] The mesh tube outer peripheral thread body may be formed in a substantially cylindrical shape.

[0081] The outer diameter of the outer circumferential filament of the mesh tube can be, for example, 3 to 30 mm, and is preferably substantially constant. The natural diameter of the outer circumferential filament of the mesh tube is preferably 4 to 15 mm, more preferably 5 to 10 mm.

[0082] (3-2) Cylindrical outer periphery

[0083] The cylindrical outer circumferential portion is made of a non-water-absorbent or low-water-absorbent material and is formed in a net-like shape, that is, in a cylindrical shape using a knit or other net-like or mesh-like structure.

[0084] The knit or other net-like or mesh-like structure may be made of, for example, a yarn in which non-absorbent or low-absorbent monofilaments are twisted, but is not limited to this.

[0085] Such non-water-absorbent or low-water-absorbent single fibers can be single fibers having a water absorption rate of, for example, 3% or less at 20°C and a relative humidity of 65%. Preferably, the water absorption rate is 2% or less, and more preferably 1% or less, at 20°C and a relative humidity of 65%. Such single fibers can be made of, for example, filaments of polyester fibers, polypropylene fibers, polyethylene fibers, polyamide fibers, etc. (preferably polyester fibers, polypropylene fibers, or polyethylene fibers), and if necessary, all or part of the single fibers can be subjected to a hydrophilization treatment using various surfactants, etc.

[0086] The fineness of the single fiber may be, for example, 0.5 to 5 denier, preferably 0.8 to 3 denier.

[0087] The average flatness of the cross section of the single fiber can be, for example, less than 0.5 (for example, 0 or more and less than 0.5), preferably 0 to 0.4, and more preferably 0 to 0.3.

[0088] (3-3) Single fiber bundle

[0089] A large number of non-water-absorbent or low-water-absorbent bundles of monofilaments (such as bundles of filaments or tows, where the monofilaments are not twisted into a thread or bundled by twisting) are accommodated within the mesh-shaped cylindrical outer peripheral portion along the axis of the cylindrical outer peripheral portion (for example, in a state continuous in the axial direction with the cylindrical outer peripheral portion) to form a mesh-tube outer peripheral thread. The axial length of the monofilament bundle is preferably the same as the axial length of the cylindrical outer peripheral portion. For example, the mesh-tube outer peripheral thread may be configured by accommodating two or more monofilament bundles having an axial length equal to that of the cylindrical outer peripheral portion in parallel within the cylindrical outer peripheral portion, or by accommodating one monofilament bundle having an axial length equal to that of the cylindrical outer peripheral portion within the cylindrical outer peripheral portion.

[0090] In the woven fabric of the present invention, the axial direction of the bundle of monofilaments in the cylindrical outer periphery is, for example, bent according to the change in the axial direction of the mesh cylinder outer periphery yarn, i.e., the change in the axial direction of the cylindrical outer periphery.

[0091] The non-water-absorbent or low-water-absorbent single fibers in the single fiber bundle (tow, etc.) can have a water absorption rate of, for example, 3% or less at 20°C and a relative humidity of 65%. Preferably, the water absorption rate is 2% or less, and more preferably 1% or less, at 20°C and a relative humidity of 65%. Such single fibers can be made of, for example, filaments of polyester fibers, polypropylene fibers, polyethylene fibers, polyamide fibers, etc. (preferably polyester fibers, polypropylene fibers, or polyethylene fibers), and if necessary, all or part of the single fibers can be subjected to a hydrophilization treatment using various surfactants, etc.

[0092] The fineness of the single fiber is, for example, 0.8 to 15 denier, preferably 1.5 to 12 denier, more preferably 2 to 10 denier, and even more preferably 4 to 7 denier.

[0093] The average flatness of the cross section of the single fiber can be, for example, less than 0.5 (for example, 0 or more and less than 0.5), preferably 0 to 0.4, and more preferably 0 to 0.3.

[0094] (3-4) Suction and discharge of aqueous liquid from the outer thread of the mesh tube

[0095] The mesh tubular outer yarn body is relatively easy to absorb and discharge water or other water-based liquids through the tubular outer periphery into the bundle of single fibers within the tubular outer periphery.

[0096] (3-5) Pitch of the outer thread of the mesh tube

[0097] The pitch of the mesh tube outer thread body can be, for example, 0.3 to 0.8 times the sum of the outer diameters of adjacent mesh tube outer thread bodies (if it is the pitch of the warp thread, it is the mesh tube outer thread body that makes up the warp thread, and if it is the pitch of the weft thread, it is the mesh tube outer thread body that makes up the weft thread), and preferably, for example, 0.4 to 0.6 times the sum of the outer diameters.

[0098] The outer diameter of the hem-like thread of the present invention, which holds a large number of single fibers as decorative threads around a core yarn and which is densely packed circumferentially so as to form a radial pattern around the core yarn, with the density increasing toward the inside and the density increasing in the axial direction, is less susceptible to shrinkage due to compression force than the outer diameter of the net-tube outer thread of the present invention, which is formed by accommodating a large number of bundles of single fibers within a net-shaped cylindrical outer peripheral portion along the axis of the cylindrical outer peripheral portion. Conversely, the outer diameter of the net-tube outer thread of the present invention is more susceptible to shrinkage than the outer diameter of the hem-like thread of the present invention. Therefore, the pitch of the net-tube outer thread of the present invention as a weft yarn is likely to become relatively large due to the presence of the hem-like thread as a warp yarn.

[0099] For example, if two types of warp threads, one with an outer diameter of 10 mm (larger than the outer diameter of the mesh tube outer peripheral thread) and the other with an outer diameter of 5 mm (smaller than the outer diameter of the mesh tube outer peripheral thread), are used alternately adjacent to each other, and a mesh tube outer peripheral thread with an outer diameter of 7.5 mm is used as the weft, the pitch of the mole-shaped threads (the pitch of two adjacent types of mole-shaped threads) can be 4.5 mm (less than 0.5 times the sum of the outer diameters of adjacent mole-shaped threads), and the pitch of the mesh tube outer peripheral threads can be 9 mm (more than 0.5 times the sum of the outer diameters of adjacent mesh tube outer peripheral threads).

[0100] (4) Fabric flexibility and water-based liquid absorption and desorption

[0101] As described above, the outer diameter of the mesh tube outer thread in the present invention is more easily reduced than the outer diameter of the mall-shaped thread in the present invention, so by using one of the warp and weft threads of the woven fabric of the present invention as a mall-shaped thread and the other as the mesh tube outer thread, the flexibility of the woven fabric and its ability to adapt to the unevenness of the object to be wiped as a wiping cloth are good.

[0102] In addition, the mole-shaped thread, which is either the warp or weft thread, has a water absorption force acting from the outer periphery inward due to capillary action, while the other, the mesh tube outer thread, is relatively easy to absorb and discharge through the tubular outer periphery into the bundle of single fibers within the tubular outer periphery, thereby achieving good water absorption and dewatering properties overall.
