[Effects of the Invention]
[0007] According to the present invention, a quick-drying fabric and textile product can be obtained that includes elastic fiber yarn and core-sheath type blended fiber yarn, and is excellent not only in quick-drying properties but also in stretchability, a voluminous and soft texture, anti-stickiness properties, and anti-snagging properties. [Modes for carrying out the invention]
[0008] Embodiments of the present invention will now be described in detail. First, the fabric of the present invention comprises an elastic fiber yarn and a core-sheath type blended yarn (hereinafter sometimes referred to as "blended yarn"), wherein the core and sheath portions of the blended yarn are composed of multifilaments that have not undergone false-twist crimping (hereinafter sometimes referred to as "unfalse-twisted yarn"). Multifilaments that have not undergone false-twist crimping are uncrimped yarns and are sometimes referred to as raw silk. By constructing the blended yarn with multifilaments that have not undergone false-twist crimping, quick-drying properties are added to the fabric. If crimped yarns such as false-twist crimped yarns are arranged in the core or sheath portion of the blended yarn, the quick-drying properties may decrease, which is undesirable. In the present invention, multifilaments that have not undergone false-twist crimping may be subjected to air processing such as interlacing or twisting.
[0009] In the aforementioned blended yarn, it is preferable that the total fineness is within the range of 50 to 150 dtex (more preferably 70 to 130 dtex). If the total fineness of the blended yarn is smaller than the above range, the density of the quick-drying fabric will decrease, which may make snagging more likely. Conversely, if it exceeds the above range, the texture of the fabric may become stiff, and the weight may become too high.
[0010] Furthermore, the number of filaments in the core and / or sheath portion of the blended yarn is preferably in the range of 20 to 200. In particular, it is preferable that both the core and the sheath portion have a number of filaments in the range of 20 to 200.
[0011] As the function of the sheath part in the conjugate fiber, first, the sheath part on the skin side instantaneously absorbs and diffuses the sweat that has perspired, transfers it to the core part, and at the same time, also transfers and diffuses it to the outer sheath part, adding appropriate swelling and a soft texture to the fabric. In order to enhance the water absorption and diffusion effect and achieve a soft texture, the single fiber fineness of the sheath part is preferably 3.0 dtex or less (more preferably 0.001 to 1.3 dtex). The cross-sectional shape of the fiber constituting the sheath part is not particularly limited, but an irregular cross-section is preferred. Regarding the irregular cross-section, any of triangle, flat, Y-shaped, W-shaped, cross-shaped, etc. may be used. Particularly, in terms of water absorption, quick drying, and a soft texture with swelling, a flat cross-section is preferred, and a flat cross-section with a constricted part is more preferred than a flat flat cross-section.
[0012] On the other hand, as the function of the core part, it is to instantaneously absorb and diffuse the moisture absorbed and diffused by the sheath part on the skin side using capillary action and transfer it to the outer sheath part. From the viewpoints of water absorption and diffusibility, the single fiber fineness of the core part is preferably 0.5 dtex or more, and more preferably in the range of 0.9 to 2.2 dtex. When the single fiber fineness is smaller than the above range, the water absorption and texture are good, but there is a possibility that the quick drying property may be insufficient. On the other hand, when it is larger than the above range, the texture becomes hard, and it may be difficult to obtain the desired fabric. The cross-sectional shape of the fiber constituting the core part is not particularly limited and may be an irregular cross-section as described above or a round cross-section.
[0013] As the type of polymer forming the multifilament arranged in the core part and / or sheath part, polyester or aliphatic polyamide (such as nylon 6, nylon 66, etc.) is preferable. Among them, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, polyester copolymerized with a third component, etc. are more preferably exemplified. Such polyester may be a polyester recycled by material recycling or chemical recycling. Furthermore, a polyester obtained by using a catalyst containing a specific phosphorus compound and titanium compound as described in JP-A-2004-270097 and JP-A-2004-211268 may also be used. In the polymer, within a range not impairing the object of the present invention, a micropore-forming agent, a cationic dye-dyeable agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent, a moisture absorbent, and inorganic fine particles may be contained in one or more kinds. Particularly, when the matting agent is contained at 0.1% by weight or more (more preferably 0.3 to 2.0% by weight) based on the polymer weight, the anti-permeability is improved, which is preferable. Specifically, semi-dull polyester, full-dull polyester, and cation-dyeable polyester are preferable. When a cationic dye-dyeable agent (such as an ester-forming sulfonic acid metal salt compound) is contained in the polyester, antibacterial and deodorant properties are added by acid treatment as described in WO 2011 / 048888 pamphlet, which is preferable.
[0014] In the present invention, examples of the elastic fiber yarn include polyurethane fiber, composite fiber in which two components are joined in a side-by-side type or eccentric core-sheath type, and polytrimethylene terephthalate fiber.
[0015] Preferably, the composite fiber is composed of at least one component of polytrimethylene terephthalate, polybutylene terephthalate, or polyethylene terephthalate. Specifically, examples of such two components include polytrimethylene terephthalate and polytrimethylene terephthalate, polytrimethylene terephthalate and polyethylene terephthalate, polyethylene terephthalate and polyethylene terephthalate, and polyethylene terephthalate and polybutylene terephthalate.
[0016] Here, polytrimethylene terephthalate refers to a fiber made of polyester whose main repeating unit is trimethylene terephthalate units, and specifically refers to a fiber in which trimethylene terephthalate units are present in an amount of 50 mol% or more, preferably 70 mol% or more, more preferably 80 mol% or more, and particularly preferably 90 mol% or more. Therefore, it contains polytrimethylene terephthalate in a total amount of other acid components and / or glycol components as a third component that is within the range of 50 mol% or less, preferably 30 mol% or less, more preferably 20 mol% or less, and particularly preferably 10 mol% or less.
[0017] Polytrimethylene terephthalate is produced by condensing terephthalic acid or a functional derivative thereof with trimethylene glycol or a functional derivative thereof under appropriate reaction conditions in the presence of a catalyst.
[0018] Examples of the third component to be added include aliphatic dicarboxylic acids (oxalic acid, adipic acid, etc.), alicyclic dicarboxylic acids (cyclohexanedicarboxylic acid, etc.), aromatic dicarboxylic acids (isophthalic acid, sodium sulfisoisophthalic acid, etc.), aliphatic glycols (ethylene glycol, 1,2-trimethylene glycol, tetramethylene glycol, etc.), alicyclic glycols (cyclohexaneglycol, etc.), aromatic dioxy compounds (hydroquinone bisphenol A, etc.), aromatic aliphatic glycols (1,4-bis(β-hydroxyethoxy)benzene, etc.), and aliphatic oxycarboxylic acids (p-oxybenzoic acid, etc.). The polyethylene terephthalate may be obtained by copolymerizing the three components. It may also be obtained through material recycling or chemical recycling. Furthermore, it may be obtained using a catalyst containing specific phosphorus and titanium compounds, as described in Japanese Patent Publication No. 2004-270097 and Japanese Patent Publication No. 2004-211268.
[0019] The aforementioned polytrimethylene terephthalate, polyethylene terephthalate, polybutylene terephthalate, etc., may contain one or more types of micropore-forming agents, cationic dyeing agents, color inhibitors, heat stabilizers, fluorescent whitening agents, matting agents, colorants, hygroscopic agents, and inorganic fine particles. The aforementioned composite fiber can be manufactured, for example, by the method described in Japanese Patent Publication No. 2009-46800.
[0020] In the present invention, the elastic fiber yarn may be included in the fabric as a single yarn, or as a composite yarn (such as an air-blended yarn) with other yarns (for example, a non-crimped yarn). In this case, the elastic fiber yarn is preferably in the range of 0.00002 to 3.0 dtex (more preferably 0.1 to 2.0 dtex, and especially preferably 0.3 to 1.0 tex) in order to obtain an excellent texture.
[0021] While there are no particular restrictions on fibers other than the stretchable fiber yarns and core-sheath type blended yarns that make up the fabric, polyester fibers made of polyester are preferred. Examples of such polyesters include polyesters in which terephthalic acid is the main acid component and at least one glycol selected from the group consisting of alkylene glycols having 2 to 6 carbon atoms, namely ethylene glycol, trimethylene glycol, tetramethylene glycol, pentamethylene glycol, and hexamethylene glycol, with ethylene glycol being particularly preferred as the main glycol component.
[0022] Such polyesters may contain small amounts (usually 30 mol% or less) of copolymer components as needed. Examples of bifunctional carboxylic acids other than terephthalic acid that can be used include aromatic, aliphatic, and alicyclic bifunctional carboxylic acids such as isophthalic acid, naphthalene dicarboxylic acid, diphenyl dicarboxylic acid, diphenoxyethane dicarboxylic acid, β-hydroxyethoxybenzoic acid, p-oxybenzoic acid, 5-sodium sulfoisophthalic acid, adipic acid, sebacic acid, and 1,4-cyclohexanedicarboxylic acid. Examples of diol compounds other than the glycols mentioned above include aliphatic, alicyclic, and aromatic diol compounds such as cyclohexane-1,4-dimethanol, neopentyl glycol, bisphenol A, and bisphenol S, and polyoxyalkylene glycols.
[0023] The aforementioned polyester may be synthesized by any method. For example, in the case of polyethylene terephthalate, it may be produced by a first-step reaction in which terephthalic acid and / or a low polymer thereof are produced by directly esterifying terephthalic acid and ethylene glycol, or by transesterifying a lower alkyl ester of terephthalic acid such as dimethyl terephthalate with ethylene glycol, or by reacting terephthalic acid with ethylene oxide, and a second-step reaction in which the reaction product from the first step is heated under reduced pressure and subjected to polycondensation until the desired degree of polymerization is reached. It may also be a material-recycled or chemically recycled polyester. Furthermore, it may be an aliphatic polyester such as polylactic acid or stereocomplex polylactic acid.
[0024] The aforementioned polyester may contain, as needed, a matting agent (titanium dioxide), a micropore-forming agent (organic sulfonic acid metal salt), a color inhibitor, a heat stabilizer, a flame retardant (antimony trioxide), and a fluorescence enhancer. Whitening agents, coloring pigments, antistatic agents (metal sulfonates), hygroscopic agents (polyoxyalkylene glycols), antibacterial agents, and one or more other inorganic particles may be included. In particular, the poly It is preferable that the ester contains 0.2% or more (more preferably 0.2-2.5% by weight) of a matting agent relative to the weight of the polyester, as this adds UV shielding and opacity.
[0025] The method for manufacturing the fabric of the present invention involves first preparing a non-false-twisted yarn for the core and a non-false-twisted yarn for the sheath. In this case, for the blended yarn to form a core-sheath structure, the boiling water shrinkage rate of the core must be greater than that of the sheath. For example, as the non-false-twisted yarn for the core, yarns obtained by cold-drawing undrawn polyester yarn (UDY) or partially oriented polyester yarn (POY) are preferable because they have a high boiling water shrinkage rate.
[0026] Next, the non-twisted yarn for the core and the non-twisted yarn for the sheath are brought together, and a blended yarn is obtained by an air blending method such as interlacing or a twisting method. In particular, it is preferable that the interlacing is performed at a rate of 30 or more strands / m (more preferably 60 to 200 strands / m).
[0027] The hot water shrinkage rate of such blended yarns is preferably 40% or more (more preferably 40-60%) from the viewpoint of the snagging resistance of the fabric. If the hot water shrinkage rate is less than 40%, the blended yarns will not shrink sufficiently during the dyeing process, resulting in a lower density of the quick-drying fabric. Therefore, if the quick-drying fabric gets caught on a sharp object, the threads may be pulled out, potentially reducing its snagging resistance. On the other hand, if the hot water shrinkage rate is greater than 40%, the blended yarns shrink more during the dyeing process, increasing the density of the fabric. As a result, while the snagging resistance improves, the texture may become stiffer, and the quick-drying properties may decrease.
[0028] Next, the stretchable fiber yarn and the blended fiber yarn are woven using a loom (for example, a water jet loom). In this case, it is preferable that the woven fabric contains the elastic fiber yarn in at least one of the warp and weft threads, and that the core-sheath type blended fiber yarn in at least one of the warp and weft threads. For example, it is preferable to arrange the elastic fiber yarn in one of the warp and weft threads, and the elastic fiber and the core-sheath type blended fiber yarn in the other (for example, in a ratio of 1:10 to 10:1). The structure of the woven fabric is not limited, and plain weave, twill weave, satin weave, etc., are preferred examples. Double weave structures such as warp double weave, weft double weave, and warp and weft double weave are also acceptable. Among these, a double weave with a convex structure on the back surface is preferred in order to obtain excellent anti-stickiness properties.
[0029] Next, dyeing and water absorption (sweat absorption) processing are applied as appropriate to obtain a woven fabric. Due to the heat history of dyeing and other processing, the core fibers contained in the blended yarn shrink significantly, and the blended yarn becomes a core-sheath type. At this time, it is preferable that the difference in yarn length between the core and sheath contained in the blended yarn is 40% or more (more preferably 50-80%). Furthermore, in order to make the difference in yarn length between the core and sheath contained in the blended yarn 40% or more, for example, it is preferable to use a cold-drawn yarn of polyester undrawn yarn (UDY) or polyester partially oriented yarn (POY) as the non-false-twisted yarn for the core, while a drawn yarn spun and drawn (heat-drawn) of polyester by a conventional method is used as the non-false-twisted yarn for the sheath.
[0030] The following methods are examples of methods for measuring the difference in thread length between the core and the sheath. First, a tubular knitted fabric is knitted using blended yarn, dyed, and then the tubular knitted fabric is immersed in a sodium hydroxide solution, heated, and dried to reduce the amount of core yarn. Subsequently, a predetermined load is applied to the length of a predetermined wale (L1) of the blended yarn extracted from the tubular knitted fabric before weight reduction and the same wale length (L2) of the blended yarn extracted from the tubular knitted fabric after weight reduction, and the difference in yarn length is calculated using the following formula. Thread length difference (%)=(L2-L1) / L1×100
[0031] While there are no specific limitations on the weight of the fabric, considering softness, dryness, and intended use, 80-300 g / m² is generally recommended. 2A fast-drying material with a basis weight of 300 g / m² is preferred. 2 If it exceeds that, it may become too heavy as clothing.
[0032] Furthermore, such textiles may be subjected to various processes, such as conventional napping, ultraviolet shielding, or processes that impart functions such as antibacterial agents, deodorizers, insect repellents, phosphorescent agents, retroreflective agents, and negative ion generators, as long as the objectives of the present invention are not impaired.
[0033] Because the fabric of the present invention has the above-described structure, it is excellent not only in quick-drying properties but also in stretchability, a soft, puffy texture, anti-stickiness properties, and anti-snagging properties. Here, it is preferable that the diffusible residual moisture content (L0) of the fabric is 30 minutes or less (more preferably 1 to 30 minutes). However, the diffusible residual moisture content is calculated by dropping approximately 0.6 g of water onto the sample in an atmosphere of 20°C × 65% RH, measuring the mass at each time point, and so on. Residual moisture content (%) = Moisture content at each time point (g) / Moisture content immediately after dropping (back side) (g) × 100 Measure the time it takes for the residual moisture content to drop below 10%. A shorter time is better (faster drying).
[0034] Furthermore, it is preferable that the stretchability in the warp or weft direction (preferably both warp and weft) is 8% or more (more preferably 10-30%). However, the elongation (stretchability) of the fabric shall be measured according to JIS L1096-2010 8.16 B method.
[0035] Furthermore, in woven fabrics, it is preferable that the wet friction force be 100g or less (more preferably 10 to 90g). However, the wet friction force is measured by the following measurement method. A piece of fabric to be measured, 15cm long and 6cm wide, is placed on a metal roller with a diameter of 8cm and a polished surface. One end is attached to a stress strain gauge (U gauge), and a 10g clip is attached to the lower end to tension the fabric. Next, while rotating the metal roller at a surface speed of 7cm / sec in the opposite direction to the U gauge, exactly 1cc of water is gently injected between the metal roller and the fabric using a syringe. At this time, the tension on the fabric is measured via the U gauge and recorded with a recorder, and the maximum value is defined as the wet friction force.
[0036] Furthermore, it is preferable that the anti-snagging properties of the fabric be grade 3 or higher. However, this should be tested for 5 hours using a kananoko according to JIS L1058-1995 D3 method. Furthermore, in woven fabrics, it is preferable that the tear strength in the warp or weft direction (preferably both warp and weft) be 7N or higher (preferably 8 to 30N). However, the tear strength shall be measured according to JIS L 1096-2010 8.17 Method D.
[0037] Furthermore, in woven fabrics, it is preferable that the slip resistance force is 3 mm or less (more preferably 0.1 to 2 mm). However, the slip resistance force shall be measured according to JIS L 1096-2010 8.23 Method B (load 117.7 N).
[0038] Next, the textile product of the present invention is any textile product selected from the group consisting of sportswear, outerwear, innerwear, men's clothing, women's clothing, nursing care clothing, work clothes, car seat upholstery material, and bedding, made using the aforementioned woven fabric. Because such textile products use the aforementioned fabric, they offer excellent quick-drying properties, stretchability, a voluminous texture, anti-stickiness, and anti-snacking properties. [Examples]
[0039] Next, the present invention will be described in detail with reference to examples, but the present invention is not limited in any way by these examples. The physical properties in the examples were measured by the following methods.
[0040] (1) Measuring Measurement shall be performed according to JIS L1018-1998 6.4.
[0041] (2) Diffusible residual moisture content Approximately 0.6 g of water is dropped onto the sample in an atmosphere of 20°C and 65% RH, and the mass is measured at each time point to calculate the diffusible residual moisture content. Residual moisture content (%) = Moisture content at each time point (g) / Moisture content immediately after dropping (back side) (g) × 100 Measure the time it takes for the residual moisture content to drop below 10%. A shorter time is better (faster drying).
[0042] (3) Anti-snagging properties The test will be conducted for 5 hours using a hacksaw according to the JIS L1058-1995 D3 method.
[0043] (4) Thread difference After knitting a tubular knitted fabric using blended yarn, it is dyed. Next, 3.75g of the tubular knitted fabric is immersed in 250ml of 50g / L sodium hydroxide solution, the temperature is raised at 2°C / min, and the temperature is maintained at 80°C for 270 minutes, after which the core yarn is dried to reduce its weight. Subsequently, the length of the 50-wale blended yarn extracted from the tubular knitted fabric before weight reduction (L1) and the length of the 50-wale blended yarn extracted from the tubular knitted fabric after weight reduction (L2) are measured by applying a load of 3.6g to each, and the difference in yarn length is calculated using the following formula. Thread length difference (%)=(L2-L1) / L1×100
[0044] (5) Coverage Factor The elongation coverage factor (elongation CF) and latitude coverage factor (latitude CF) were calculated using the following formulas. Cash flow = (DWp / 1.1) 1 / 2 ×MWp Latitude CF=(DWf / 1.1) 1 / 2 ×MWf [DWp represents the total warp fineness (dtex), MWp represents the warp weave density (threads / 2.54cm), DWf represents the total weft fineness (dtex), and MWf represents the weft weave density (threads / 2.54cm).]
[0045] (6) Stretchability The elongation (stretchability) of the fabric was measured according to JIS L1096-2010 8.16 Method B.
[0046] (7) Tear strength of the fabric The tear strength (N) was measured according to JIS L1096-2010 8.17 Method D.
[0047] (8) Resistance to slippage of fabrics The measurement was performed according to JIS L1096-2010 8.23 Method B, with a load of 117.7 N (mm).
[0048] (9) Method for measuring wet friction force First, a piece of fabric to be measured, measuring 15 cm in length and 6 cm in width, was placed on a polished metal roller with a diameter of 8 cm. One end was attached to a stress strain gauge (U gauge), and a 10 g clip was attached to the lower end to tension the fabric. Next, while rotating the metal roller in the opposite direction of the U gauge at a surface speed of 7 cm / sec, exactly 1 cc of water was gently injected between the metal roller and the fabric using a syringe. At this time, the tension on the fabric was measured via the U gauge and recorded with a recorder, and the maximum value was defined as the wet friction force.
[0049] (10) Texture In terms of softness, it will be evaluated on a three-point scale: excellent (○), average (△), and poor (×).
[0050] [Example 1] As a cationic dyeable polyester, a cationic dyeable POY (partially oriented yarn) consisting of polyethylene terephthalate copolymerized with 1.5 mol% sodium 5-sulfoisophthalate salt, with a total fineness of 90 dtex / 36fil, a breaking strength of 2.0 cN / dtex, and a breaking elongation of 148%, was cold-drawn at a stretch ratio of 1.6 times (total fineness 56 dtex / 36fil, non-crimped) and a flattened polyethylene terephthalate drawn yarn with a cross-sectional flatness of 3.2 and three constrictions along the long axis of the fiber cross-section (total fineness 44 dtex / 36fil, titanium dioxide content 2.4%, non-crimped) were joined together and interlaced with a 2% overfeed to obtain a blended yarn with a yarn length difference of 55% (total fineness 107 dtex / 72fil, interlacing degree 106 fibers / m).
