Description

  The present invention relates to a textile product excellent in wrinkle resistance and dyeability.

  A woven fabric containing cellulose fibers generally tends to retain wrinkles generated by washing and has a low wash and wear property (W & W property). Therefore, conventionally, in order to improve the W & W property, a method of chemically cross-linking cellulose molecules using a cellulose cross-linking agent has been used.

  On the other hand, when both the W & W property and the color pattern are imparted to the woven fabric containing cellulose fibers, there is a problem that if the woven fabric is dyed after being chemically cross-linked, no color is developed or the hue becomes uneven. Therefore, a method of chemically cross-linking a woven fabric using pre-dyed yarn or a method of chemically cross-linking after dyeing the woven fabric is used. However, these methods have a problem that the hue changes due to chemical cross-linking, and the pattern is deformed along with the dimensional change of the fabric. Furthermore, it is economically expensive to incorporate a favorite pattern for each small lot (for example, for each sheet).

  On the other hand, a method for enhancing dyeability in a subsequent process by a form stabilizing method without chemical crosslinking (Patent Document 1) and a method for ink-jet printing on a silk fabric having improved W & W properties by chemical crosslinking (Patent Document 2) Has been proposed. However, the method described in Patent Document 1 is insufficient in imparting W & W properties. Moreover, although the method of patent document 2 is effective with respect to a silk fabric, even if it applies to the woven fabric containing a cellulose fiber, it cannot make W & W property and dyeability compatible.

  The textile product in the second embodiment of the present invention contains 60% by mass or more of cellulose fibers, and is woven using cellulosic fibers having an English cotton count of 40 to 100. The warp density is 120 to 240. / Inch, a woven product including a woven fabric other than plain weave having a weft density of 60 to 170 yarns / inch, wherein the cellulose fibers are crosslinked by a crosslinking agent in the woven fabric, and the weft direction of the woven fabric The tensile hardness is 0.54 to 0.78, the elongation in the weft direction is 4 to 17%, and the tensile recovery in the weft direction is 45 to 75%.

  The textile products of the first and second embodiments of the present invention have practically sufficient W & W properties, and cause problems such as color developability and hue non-uniformity when subjected to a dyeing process. And can be dyed satisfactorily. The reason why such an effect is obtained is not clear, but is presumed as follows. That is, it is presumed that a crosslinked structure that allows the dye to penetrate into the inside of the fiber is formed between the cellulose fibers by performing a crosslinking treatment on the woven fabric so that the mechanical properties are within a predetermined range.

  Hereinafter, the first embodiment and the second embodiment will be described in detail.

[A-1. First Embodiment]
The minimum of content of the cellulose fiber in the said cellulose fiber is 60 mass%. When the content is 60% by mass or more, a textile product excellent in water absorption and texture can be obtained. The content is preferably 70% by mass to 100% by mass, more preferably 80% by mass to 100% by mass, and still more preferably 90% by mass to 100% by mass. If it is such content, it is excellent in water absorption and a texture, and also the wrinkle prevention effect by a crosslinking process can be obtained suitably. Content of the said cellulose fiber is a value calculated | required based on JISL1030-2.

  Any appropriate cellulose fiber may be used as the cellulose fiber contained in the cellulosic fiber depending on the application. Specific examples of cellulose fibers include cotton (for example, short fiber cotton, medium fiber cotton, long fiber cotton, super long cotton, super long cotton, super long cotton), hemp, bamboo, ridges, honey, bananas, encapsulates, etc. Plant and animal natural cellulose fibers; regenerated cellulose fibers such as rayon fibers (eg, viscose rayon, copper ammonia rayon); semi-regenerated cellulose fibers such as acetate fibers (eg, bisacetate, triacetate); It is done. Among these, cotton, hemp, and rayon can be preferably used because a textile product excellent in water absorption, texture, and physical properties can be obtained. Cellulose fibers may be used alone or in combination of two or more.

  In the said cellulosic fiber, as another fiber which can be used in combination with the said cellulose fiber, arbitrary appropriate fibers may be used according to a use etc. Specific examples include polyester fiber, polyamide fiber, polyurethane fiber, polyethylene fiber, polyolefin fiber, polyimide fiber, and polylactic acid fiber. By using the polyester fiber in combination with the cellulose fiber, the effect of improving the W & W property can be obtained. By using a polyamide fiber, a polyurethane fiber, or the like in combination with the cellulose fiber, the tensile strength (LT) in the weft direction of the fabric and the tensile recovery property (RT) in the weft direction can be adjusted to a preferable range. The other fibers may be used alone or in combination of two or more.

  The cellulosic fiber may be in any suitable form depending on the purpose. Specific examples include raw yarn (unprocessed yarn), false twisted yarn, and dyed yarn. Moreover, forms, such as a single yarn, a twisted yarn, and a covering yarn, are mentioned. Moreover, when the said cellulosic fiber contains 2 or more types of fiber, the said 2 or more types of fiber may be forms, such as a blended yarn and a mixed twisted yarn, for example. These forms may be adopted alone or in combination of two or more.

  The fineness of the cellulosic fibers is 30 to 80 in English cotton count. If the fineness is less than 30th, there is a problem that the fabric becomes hard because the fibers are thick. On the other hand, when the fineness exceeds 80, there are problems such as the tensile strength and tear strength of the woven fabric are lowered because the fibers are thin, and the production cost is increased. For example, the fineness when the textile product of the present invention is used as a female handkerchief is preferably 60 to 80. The fineness when used as a blouse is preferably 40 to 80. As the yarn having a fineness of 40, a 40th single yarn, an 80th single yarn, or the like can be used.

  The woven fabric may be woven (so-called cross-weaving) using other fibers as warps and / or wefts in addition to the cellulosic fibers as necessary. Examples of the other fibers include the same fibers as the other fibers that can be blended with the cellulose fibers in the cellulosic fibers. The fineness of the other fibers is the same as that of the cellulosic fiber. When cross-weaving using other fibers, the cellulose fiber content in the entire woven fabric is preferably 60% by mass or more, more preferably 70% by mass to 100% by mass, and even more preferably 80% by mass to 100% by mass. %, Still more preferably 90% by mass to 100% by mass.

  The woven structure of the woven fabric is a plain weave. Of these, plain weave structures such as broad, lawn and gauze are preferred. For example, broad is preferable because the texture is dense and glossy. A loan is preferable in that it has a soft touch and feels like hemp.

  The woven fabric has a warp density of 100 to 200 yarns / inch and a weft density of 50 to 150 yarns / inch. When the woven density is coarser than the above range, the woven fabric has many gaps between yarns, and the strength of the woven fabric may be small. In addition, for example, when used as a handkerchief, water absorption and the like may be inferior. On the other hand, if the woven density is denser than the above range, the gap between the yarns decreases, so that the texture becomes hard, the tension becomes strong, and the woven fabric becomes heavy. From the viewpoints of performance (for example, water absorption, quick drying, softness) according to a desired application, strength, thickness and weight of the fabric, the preferred warp density is 110 to 150 yarns / inch. From the same viewpoint, the preferred weft density is 60 to 80 / inch. The warp density and the weft density may be the same as or different from each other. In addition, the woven density of the said woven fabric is a woven density of the woven fabric in the textile product obtained through the crosslinking process mentioned later. Therefore, the woven density of the woven fabric may be different from the woven density at the time of weaving.

  The woven fabric is subjected to a crosslinking treatment using a cellulose crosslinking agent. As a result, the cellulose fibers are cross-linked, and predetermined mechanical properties described later are imparted to the fabric. The crosslinking treatment will be described in detail in Section B.

  The tensile strength (LT) in the weft direction of the woven fabric is 0.82 to 0.97, preferably 0.83 to 0.96, and more preferably 0.84 to 0.96. If the tensile hardness is less than 0.82, fine dyeing such as ink jet printing may be difficult due to a decrease in W & W property, an increase in bleeding at the time of dyeing, and a decrease in surface dyeing property. On the other hand, when the tensile hardness exceeds 0.97, the W & W property can be improved, but the dyeability may be lowered, the texture of the fabric may be hardened, and the physical properties may be lowered.

  The weft extension (EMT) of the woven fabric is 3 to 12%, preferably 3 to 11%, more preferably 3 to 10%. If the elongation is less than 3%, the dyeability may decrease, the texture of the fabric may become hard, or the physical properties may decrease. On the other hand, if the elongation exceeds 12%, fine dyeing such as ink jet printing may become difficult due to a decrease in W & W property, a strong blur at the time of dyeing, and a decrease in surface dyeing property.

  The tensile recovery property (RT) in the weft direction of the woven fabric is preferably 45 to 75%, more preferably 50 to 73%, and still more preferably 50 to 70%. If the tensile recovery property is less than 45%, fine dyeing such as ink jet printing may be difficult due to a decrease in W & W property, an increase in bleeding at the time of dyeing, and a decrease in surface dyeing property. On the other hand, when the tensile recovery property exceeds 75%, the W & W property may be improved, but the dyeability may be decreased, and the physical properties of the fabric may be decreased.

  The woven fabric having the predetermined mechanical properties has practically sufficient W & W properties and exhibits excellent dyeability when subjected to a dyeing treatment. The tensile hardness (LT), elongation (EMT), and tensile recovery (RT) are mechanical properties defined by KES measurement used for measuring the texture of textile products. These physical property values can be adjusted within a desired range by appropriately setting the crosslinking treatment conditions. Specifically, by increasing the amount of the crosslinking agent used within a suitable range, the tensile hardness and the tensile recovery can be increased, and the elongation can be suppressed.

The apparent specific gravity of the woven fabric is, for example, 0.4 to 0.9 g / cm ³ , preferably 0.5 to 0.8 g / cm ³ , more preferably 0.5 to 0.7 g / cm ³ . is there. With such apparent specific gravity, the W & W property is good. Further, when the textile product is subjected to a dyeing treatment, uniform and good color developability can be obtained. The apparent specific gravity can be adjusted to a desired range by appropriately setting the weave density, fineness, adhesion amount of the crosslinking agent, and the like.

  The water retention rate of the woven fabric is preferably 15 to 30%, more preferably 19 to 28%, and still more preferably 20 to 27%. With such a water retention rate, the W & W property is good. Further, when the textile product is subjected to a dyeing treatment, uniform and good color developability can be obtained.

  The tear strength of the woven fabric is, for example, 200 cN or more, preferably higher than 500 cN, more preferably higher than 600 cN. If the tear strength is less than 200 cN, the textile product tends to be easily torn or torn during use or washing.

  The textile product in the first embodiment may be any fiber product. Specific examples include handkerchiefs, towels, sheets, covers, curtains, mats, clothes, and the like.

[A-2. Second Embodiment]
Hereinafter, with respect to the second embodiment of the present invention, description of points common to the first embodiment (cellulosic fiber configuration, presence or absence of cross-linked structure, water retention rate of fabric, tear strength, etc.) will be omitted. Different points will be described.

  The fineness of the cellulosic fibers is 40 to 100 in English cotton count. When the fineness is less than 40, there is a problem that the fabric becomes hard because the fibers are thick. On the other hand, when the fineness exceeds 100, there are problems such as the tensile strength and tearing strength of the woven fabric are lowered because the fibers are thin, and the production cost is increased. For example, the fineness when the textile product of the present invention is used as a female handkerchief is preferably 60 to 100. The fineness when used as a blouse is preferably 40 to 80. As the yarn having a fineness of 40, a 40th single yarn, an 80th single yarn, or the like can be used.

  Any appropriate woven structure other than plain weave may be adopted as the woven structure of the woven fabric. Examples include satin weave, twill weave, and dobby weave. According to these woven structures, textile products having various designs can be obtained. For example, satin weave is preferable in that it is rich in gloss and provides a smooth feel with good slippage, and by making the weave density coarse, it is possible to obtain lightweight and soft textile products of various designs.

  The woven fabric has a warp density of 120 to 240 yarns / inch and a weft density of 60 to 170 yarns / inch. When the woven density is coarser than the above range, the woven fabric has many gaps between yarns, and the strength of the woven fabric may be small. In addition, for example, when used as a handkerchief, water absorption and the like may be inferior. On the other hand, if the woven density is denser than the above range, the gap between the yarns decreases, so that the texture becomes hard, the tension becomes strong, and the woven fabric becomes heavy. From the viewpoints of performance (for example, water absorption, quick drying, softness) according to a desired application, strength, thickness and weight of the fabric, the preferred warp density is 130 to 170 yarns / inch. From the same viewpoint, the preferred weft density is 70 to 100 / inch. The warp density and the weft density may be the same as or different from each other. In addition, the woven density of the said woven fabric is a woven density of the woven fabric in the textile product obtained through the crosslinking process mentioned later. Therefore, the woven density of the woven fabric may be different from the woven density at the time of weaving.

  The tensile hardness (LT) in the weft direction of the woven fabric is 0.54 to 0.78, preferably 0.55 to 0.76, and more preferably 0.55 to 0.75. If the tensile hardness is less than 0.54, fine dyeing such as ink-jet printing may be difficult due to a decrease in the W & W property, an increase in bleeding at the time of dyeing, or a decrease in surface dyeing property. On the other hand, if the tensile hardness exceeds 0.78, the W & W property may be improved, but the dyeability may be decreased, the texture of the fabric may be hardened, and the physical properties may be decreased.

  The weft stretch (EMT) of the fabric is 4 to 17%, preferably 4 to 16%, more preferably 4 to 15%. When the elongation is less than 4%, the dyeability may decrease, the texture of the fabric may become hard, or the physical properties may decrease. On the other hand, if the elongation exceeds 17%, fine dyeing such as ink jet printing may be difficult due to a decrease in W & W property, a strong blur at the time of dyeing, or a decrease in surface dyeing property.

  The tensile recovery (RT) in the weft direction of the fabric is 45 to 75%, preferably 45 to 73%, more preferably 45 to 70%. If the tensile recovery property is less than 45%, fine dyeing such as ink jet printing may be difficult due to a decrease in W & W property, an increase in bleeding at the time of dyeing, and a decrease in surface dyeing property. On the other hand, when the tensile recovery property exceeds 75%, the W & W property may be improved, but the dyeability may be decreased, and the physical properties of the fabric may be decreased.

The apparent specific gravity of the woven fabric is, for example, 0.2 to 0.7 g / cm ³ , preferably 0.3 to 0.6 g / cm ³ , more preferably 0.4 to 0.5 g / cm ³ . is there. With such apparent specific gravity, the W & W property is good. Further, when the textile product is subjected to a dyeing treatment, uniform and good color developability can be obtained. The apparent specific gravity can be adjusted to a desired range by appropriately setting the weave density, fineness, adhesion amount of the crosslinking agent, and the like.

According to these cyclic urea compounds and epoxy compounds, a crosslinked structure (for example, a crosslinking density and a distance between crosslinking points) having a space where the dye can reach the cellulose dyeing seat can be suitably formed. The dyeability after application can be improved. In particular, since the above epoxy compound has a slightly low affinity with cellulose, it is easy to form a crosslinked structure in the vicinity of the surface rather than inside the cellulosic fiber, and as a result, the fabric is not excessively hydrophobized, and the dye It is presumed that the moisture as a carrier easily penetrates into the fiber.

  Examples of the ethylene urea type cyclic urea compound include dimethylol ethylene urea, dimethylol dihydroxy ethylene urea, dimethyl dihydroxy ethylene urea and the like. Examples of the epoxy compound having an epoxy group at both ends of the molecule include diglycidyl ether, ethylene glycol diglycidyl ether, diethylene glycol diglycidyl ether, triethylene glycol diglycidyl ether, polyethylene glycol diglycidyl ether, glycerin diglycidyl ether, butane. Examples thereof include diol diglycidyl ether.

  In the crosslinking treatment, the crosslinking agent is generally used as a crosslinking treatment solution dissolved or dispersed in water or the like. The solid content concentration of the crosslinking agent in the crosslinking treatment liquid (the total concentration when two or more crosslinking agents are used) can be appropriately set according to the type of the crosslinking agent and the like. When it is assumed that the application rate of the crosslinking treatment liquid to the woven fabric (weight of the crosslinking treatment solution contained in the woven fabric / weight of the woven fabric before application of the crosslinking treatment solution × 100) is 70%, the solid content of the crosslinking agent in the crosslinking treatment solution The concentration can be, for example, 2 to 33% by weight. More specifically, when an ethylene urea type cyclic urea compound is used as a cross-linking agent, a viewpoint of forming a cross-linked structure that gives the above-mentioned predetermined mechanical properties to a woven fabric and can obtain W & W properties while maintaining dyeability. Therefore, the solid content concentration of the crosslinking agent in the crosslinking treatment liquid is preferably 2 to 15% by mass, more preferably 2 to 13% by mass, and further preferably 2 to 11% by mass. In addition, when an epoxy compound having an epoxy group at both ends of the molecule is used as a cross-linking agent, a viewpoint of forming a cross-linked structure capable of providing the above-mentioned predetermined mechanical properties to the fabric and obtaining W & W properties while maintaining dyeability. Therefore, the solid content concentration of the crosslinking agent in the crosslinking treatment liquid is preferably 3 to 33% by mass, more preferably 4 to 30% by mass, and still more preferably 5 to 30% by mass. When the application rate of the crosslinking treatment liquid to the woven fabric is different from 70%, the solid content concentration of the crosslinking agent in the crosslinking treatment liquid described above is set in inverse proportion to the change rate of the application rate of the crosslinking treatment liquid to the woven fabric. What is necessary is just to increase / decrease (for example, when this provision rate is 35%, the density | concentration of the crosslinking agent in a crosslinking process liquid may be 4-66 mass%).

  A catalyst can be added to the crosslinking treatment liquid in order to increase the reactivity between the crosslinking agent and cellulose and to perform the crosslinking treatment quickly. The catalyst is not particularly limited as long as it is a catalyst usually used for resin processing of cellulosic fibers, and borofluorinated compounds such as ammonium borofluoride, sodium borofluoride, potassium borofluoride, zinc borofluoride and the like. Neutral metal salt catalysts such as magnesium chloride, magnesium sulfate and magnesium nitrate; inorganic acids such as phosphoric acid, hydrochloric acid, sulfuric acid, sulfurous acid, hyposulfite and boric acid; and zinc tetrafluoroborate. If necessary, these catalysts can be used in combination with an organic acid such as citric acid, tartaric acid, apple acid, maleic acid or the like as a cocatalyst.

  The amount of the catalyst used is preferably 0.5 to 10% by mass, more preferably 1 to 7% by mass with respect to the crosslinking agent. When the amount of the catalyst used is less than 0.5% by mass, the reaction yield decreases, the amount of crosslinking decreases, and the effect may be insufficient. On the other hand, when the amount of the catalyst used exceeds 10% by mass, the strength of the fiber may be lowered due to acid decomposition of the cellulosic fiber, or it may cause discoloration.

  If necessary, an auxiliary agent for smoothly advancing the reaction between the cellulose and the crosslinking agent can be added to the crosslinking treatment liquid. The auxiliary agent has an action as a reaction solvent that promotes the reaction between the crosslinking agent and cellulose, or promotes the reaction even in the crosslinking formation reaction, and further has an action of swelling the cellulose. Examples of the auxiliary agent include polyhydric alcohols such as glycerin, ethylene glycol, polyethylene glycol, and polypropylene glycol, ethylene glycol monoethyl ether, diethylene glycol monoethyl ether, ethylene glycol monomethyl ether, diethylene glycol monomethyl ether, and diethylene glycol monobutyl ether. Nitrogen-containing solvents such as ether alcohols, dimethylformamide, morpholine, 2-pyrrolidone, dimethylacetamide, N-methylpyrrolidone, ethyl acetate, isopropyl acetate, butyl acetate, amyl acetate, ethylene glycol monomethyl ether, ethylene glycol monoethyl acetate Examples thereof include esters such as ether and γ-butyrolactone. These can be used individually by 1 type or in mixture of 2 or more types.

  0.1-10 mass% is preferable with respect to a crosslinking agent, and, as for the usage-amount of the said adjuvant, More preferably, it is 1-5 mass%. When the usage-amount of auxiliary agent is less than 0.1 mass%, the effect which makes reaction smooth may become inadequate. On the other hand, when the usage-amount of an auxiliary agent exceeds 10 mass%, it may cause embrittlement of a cellulose or it may become complicated to remove an auxiliary agent from cloth after a crosslinking process.

  In addition to the above-described components, the crosslinking treatment liquid may contain a softening agent for adjusting the texture, a formalin catcher for reducing free formalin concentration, a surfactant as a penetrating agent, and the like. it can. For example, those that may generate formalin such as melamine derivatives and cyclic urea resins are preferably used in combination with a formalin catcher agent. Moreover, when a tear strength and tensile strength fall because bridge | crosslinking cellulose becomes hard, combined use of a softening agent is preferable. Moreover, when the permeability of the crosslinking treatment liquid to the fabric is low, it is preferable to use a penetrant in combination. The residual formalin in the textile product of the present invention is preferably 75 ppm or less. If it exceeds 75 ppm, skin irritation may occur during use.

  The pH of the crosslinking treatment liquid can be adjusted within a range of usually 1 to 10, preferably 2 to 9. If it is in such a range, the fall of the fiber strength and discoloration by hydrolysis of a cellulose can be prevented. The pH can be adjusted by any suitable pH adjuster.

  As a method for adhering the crosslinking treatment liquid to the woven fabric, a known method such as a normal pad / dry method, a dipping method, an impregnation method, a printing method, an ink jet printing method, a laser printer printing method, a coating method, or a spraying method is adopted. can do. For example, when processing the entire fabric, the pad dry method is efficient and preferable. When treating the entire product, it can be easily carried out by dipping or spraying.

  As for the adhesion amount of the crosslinking agent in the textile product (woven fabric) of this invention, 1.3-23.1 mass% is preferable with respect to the mass of a textile fabric. If the adhesion amount is less than 1.3% by mass, the wrinkle resistance and W & W property may not be sufficiently obtained. On the other hand, if the adhesion amount exceeds 23.1% by mass, the breaking strength and tear strength of the crosslinked cellulose fiber may be greatly reduced. However, if the physical properties (tensile strength, tear strength, burst strength, etc.) can be increased by selecting the type of cellulosic fiber, etc., the adhesion amount of the crosslinking agent can be increased. For example, if part or all of cotton yarn containing long fiber cotton, super long cotton, or super / super long cotton is used in place of the cotton yarn made of medium fiber cotton, it is effective in improving the burst strength, tensile strength and tear strength. More specifically, when an ethylene urea type cyclic urea compound is used as a cross-linking agent, a viewpoint of forming a cross-linked structure that gives the above-mentioned predetermined mechanical properties to a woven fabric and can obtain W & W properties while maintaining dyeability. Therefore, the adhesion amount of the crosslinking agent in the plain woven fabric is preferably 1.3 to 6.8% by mass, more preferably 1.3 to 5.4% by mass, and still more preferably 1. It is 3-3.6 mass%. Moreover, the adhesion amount of the crosslinking agent in the woven fabric excluding the plain woven fabric is preferably 1.3 to 10.5% by mass, more preferably 1.3 to 9.0% by mass, and still more preferably with respect to the mass of the woven fabric. Is 1.3-8.0 mass%. Next, when an epoxy compound having an epoxy group at both ends of the molecule is used as a cross-linking agent, the above-mentioned predetermined mechanical properties are imparted to the woven fabric to form a cross-linked structure capable of obtaining W & W properties while maintaining dyeability. From the viewpoint, the adhesion amount of the crosslinking agent in the plain woven fabric is preferably 2.1 to 17.5% by mass, more preferably 2.8 to 16.1% by mass, and further preferably 3 with respect to the mass of the woven fabric. 0.5 to 14.0% by mass. Moreover, the adhesion amount of the crosslinking agent in the woven fabric excluding the plain woven fabric is preferably 2.1 to 23.1% by mass, more preferably 2.8 to 21.0% by mass, and still more preferably based on the mass of the woven fabric. Is 3.5-21.0 mass%.

  The heat treatment is preferably performed at 100 to 180 ° C., more preferably 130 to 160 ° C., preferably 0.5 to 8 minutes, more preferably 1 using a heating means such as a pin tenter, steam setter, oven, baking machine or the like. It can be performed under heat treatment conditions of ˜6 minutes. Under such conditions, a sufficient amount of crosslinking can be obtained without embrittlement of the cellulose fiber or the crosslinked cellulose fiber.

[C. Dyed textile products]
According to another aspect of the present invention, a dyed textile product may be provided. The dyed fabric product is obtained by dyeing the fabric product described in Section A. The textile product is subjected to a crosslinking treatment, but may have a dyeability equivalent to that of the fabric before the crosslinking treatment. Further, the dimensional change and hue change of the fabric can be suppressed as compared with the dyed fabric product obtained by performing the crosslinking treatment after the dyeing treatment. Therefore, the dyed fabric product of the present invention obtained by dyeing the fabric product is a high-quality product.

  In the case of the dyed textile product obtained by dyeing the textile product of the first embodiment, the tensile strength (LT) in the weft direction of the plain weave fabric after dyeing is preferably 0.75 to 0.90. Preferably it is 0.76-0.89, More preferably, it is 0.77-0.88. Moreover, the elongation (EMT) in the weft direction of the plain weave fabric after dyeing is preferably 3 to 12%, more preferably 3 to 11%, and further preferably 3 to 10%. Further, the tensile recovery (RT) in the weft direction of the plain weave fabric after dyeing is preferably 45 to 75%, more preferably 50 to 73%, and still more preferably 50 to 70%. A dyed fabric product having such mechanical properties can have practically sufficient W & W properties and an exquisite color pattern without bleeding.

  In the case of a dyed fabric product obtained by dyeing the fabric product of the second embodiment, the tensile hardness (LT) in the weft direction of the woven fabric other than the plain weave after dyeing is preferably 0.53 to 0.75, More preferably, it is 0.55-0.70, More preferably, it is 0.55-0.68. Moreover, the elongation (EMT) of the wefts other than the plain weave after dyeing is 4 to 17%, more preferably 4 to 16%, and still more preferably 4 to 15%. Further, the tensile recovery (RT) in the weft direction of the woven fabric other than the plain weave after dyeing is preferably 45 to 75%, more preferably 45 to 73%, and further preferably 45 to 70%. A dyed fabric product having such mechanical properties can have practically sufficient W & W properties and an exquisite color pattern without bleeding.

[D. Method for producing dyed fabric product]
The method for producing a dyed fabric product obtained by dyeing the fabric product of the first embodiment is woven using cellulosic fibers containing 60% by mass or more of cellulose fibers and 30 to 80 English cotton counts. The resulting plain weave fabric is subjected to a crosslinking treatment using a crosslinking liquid containing a crosslinking agent, the warp density is 100 to 200 / inch, the weft density is 50 to 150 / inch, and the tensile hardness in the weft direction Is a step (Ia) of obtaining a woven fabric having a length of 0.82 to 0.97 and an elongation in the weft direction of 3 to 12%, and a step of dyeing the woven fabric obtained in the step (Ia) (step IIa). including.

  The method for producing a dyed fabric product obtained by dyeing the fabric product of the second embodiment is woven using cellulosic fibers containing 60% by mass or more of cellulose fibers and 40 to 100 English cotton counts. The woven fabric other than the plain weave is crosslinked using a crosslinking liquid containing a crosslinking agent, the warp density is 120 to 240 yarns / inch, the weft density is 60 to 170 yarns / inch, and the tensile in the weft direction A step (Ib) of obtaining a woven fabric having a hardness of 0.54 to 0.78, an elongation in the weft direction of 4 to 17%, and a tensile recovery in the weft direction of 45 to 75%, and a step ( A step of dyeing the fabric obtained in Ib) (step IIb).

  According to the above method for producing a dyed fabric product, it is possible to avoid the problem of hue change and pattern deformation caused by the crosslinking treatment in the conventional production method. Moreover, the productivity improvement effect accompanying the reduction of the in-process inventory can be obtained.

  Regarding the step (Ia) and the step (Ib), the same explanation as the crosslinking step described in the item B can be applied.

  In the step (IIa) and the step (IIb), any appropriate dyeing method can be adopted as a method for dyeing the fabric. Specific examples of the dyeing method include dip dyeing method, batch dyeing method, continuous dyeing method, cold batch method, printing method, impregnation method, printing method, ink jet printing method, laser printer printing method, coating method, spraying method and the like. It is done.

  As a dye used for dyeing, any appropriate dye such as a direct dye, a reactive dye, a vat dye, a naphthol dye, and a sulfur dye can be used. Among these, from the viewpoint of dyeability, dyeing fastness, etc., it is preferable to use a reactive dye that is dyed by chemical reaction with cellulose.

  In the step (IIa) and the step (IIb), an ink jet printing method can be applied as a dyeing method. As an inkjet printing method, for example, in Japanese Patent Application Laid-Open No. 2011-236548, a printing paper printed with a reactive dye and a cotton fabric are brought into close contact with each other, heated and pressed to attach the printing paper to the cotton fabric, and then the printing paper is used. A method (paper printing method) is described in which a cotton fabric is subjected to a steam treatment while being pasted, and a fine design is firmly and densely printed on the fabric. Conventionally, fabrics dyed by such an ink-jet textile printing method have not been provided with W & W properties, and thus have been prone to wrinkles during use or require ironing to remove wrinkles caused by washing. It was. In addition, when the design becomes more precise, blurring occurs and the resolution is limited. On the other hand, when the paper printing method is applied to the predetermined woven fabric described in the section A, a high-quality dyed woven fabric product having a high resolution and less bleeding of adjacent dyes can be obtained. Furthermore, in the obtained dyed fabric product, wrinkles are unlikely to occur during use, and wrinkles due to washing are easily removed during drying, so ironing may be unnecessary.

  EXAMPLES Hereinafter, although an Example demonstrates this invention concretely, this invention is not limited by these Examples. The measurement methods and evaluation methods used in the examples are as follows.

[Mechanical properties of the fabric (tensile hardness in the weft direction (LT), elongation in the weft direction (EMT), stretch recovery in the weft direction (RT))]
The mechanical properties of the fabric are measured by KES-FB1 (manufactured by Kato Tech) (temperature 20 ° C., humidity 65 RH%). The measurement is performed by holding a 20 cm × 20 cm sample on a chuck with a spacing of 5 cm so that the weft direction of the fabric is the tensile direction of the sample, and pulling up to a maximum load of 500 gf / cm at a strain rate of 4.00 × 10 ⁻³ / sec. Do. Tensile hardness (LT), weft direction elongation (EMT), and weft direction stretch recovery (RT) are calculated from the graph of FIG.
LT = (area of part a + area of part b) / area of triangle ABC RT = (area of part b) / (area of part a + area of part b) × 100
EMT is the elongation percentage of the sample when the maximum load is 500 gf / cm.

[Tear strength of fabric (cN)]
It measured based on JIS L-1096 D method (penjuram method). Specifically, three or more test pieces each having a length of 10 cm and a latitude of 6.3 cm were collected. Using an Elmendorf-type tear strength tester, a 2 cm cut was made with a sharp blade at a right angle to the center of the long side of the test piece at the center of both grips, and the remaining 4.3 cm of warp was The load (cN) indicated when torn was measured. The average value was defined as the tear strength in the weft direction of the fabric.
The above measuring method is a method of measuring the tear strength in the weft direction, but the tear strength in the warp direction can be measured in the same manner except that the long side of the test piece is in the weft direction. Of the tear strengths in the warp direction and the weft direction, the lower value was taken as the tear strength of the test piece.

[W & W property evaluation test of fabric]
JIS L-1096 Wrinkles after washing Washing was performed according to the A method. After dehydration, tumble drying was performed. The number of test points was 1. The W & W property was judged as an average value of three judges as compared with a replica (specified in AATCC TEST METHOD 124). The evaluation standard was evaluated in increments of 0.1. For example, in the case of grades 3.0 to 3.5, the grades were 3.1, 3.2, 3.3, 3.4, and 3.5. In general, if the W & W property is 2.0 grade or higher, the wrinkle of the textile product is reduced, if it is 3.0 grade or higher, the wrinkle is less noticeable, and if it is 3.5 grade or higher, it is ironed. Even if you do not wrinkle, it is a level where wrinkles are not noticeable.

[Apparent specific gravity of fabric]
The fabric was cut into 10 cm × 10 cm, the mass was measured, and the thickness was measured using a dough thickness meter (DS-1211) manufactured by Niigata Seiki, and the apparent specific gravity was determined.

[Dyeability of fabric]
The test was carried out based on the JIS Z 8729 color display method-L * a * b * color system. In the case of the L * a * b * color system, the color difference can be expressed by a numerical value of ΔE * ab (Delta Easter AB). The color difference (ΔE * ab) between the woven fabric to be evaluated and the same woven fabric that has not been subjected to the crosslinking treatment is obtained, and the ΔE * ab value of less than 3.2 is the best, and 3.2 to 6. The dyeability was evaluated as 5 for good and over 6.5 for poor. In general, if the value of ΔE * ab is less than 3.2, it is a level where the same color is perceived.

[Dye fastness of fabric]
The following (1) for the same fabric (control fabric) except that the fabric of the dyed fabric product obtained in each of the Examples and Comparative Examples (the fabric to be inspected) and the dyed fabric was not subjected to the crosslinking treatment. The test of (5) was conducted. When both dyeing fastnesses are the same, a zero point is given, a -1 point is given when the fabric to be inspected is inferior to the control fabric, and a +1 point is given when the fabric is dominant. . In addition, the strength of dyeing fastness is indicated by a numerical value as a grade (usually grade 5 is the strongest and grade 1 is the weakest). The grade is judged by a judgment scale defined by JIS called “gray scale”. However, only the light fastness (light resistance test) has a grade up to grade 8 (grade 8 is the strongest), and the blue scale is used for judgment.
(1) JIS L 0844 Dye fastness test method for washing The test was carried out in accordance with the A-2 method. Specifically, the test piece was processed at a temperature of 50 ° C., a soap of 5 g / L, a liquid volume of 100 ml, a test bottle of 550 ± 50 ml, and a time of 30 minutes using a launderometer called a laundry tester. Thereafter, rinsing, dehydration, and drying were performed, and the degree of fading of the test piece and the degree of contamination of the attached white cloth were determined.
(2) The test was carried out in accordance with the JIS L 0848 sweat fastness test method. Specifically, the composite test piece is placed in an acidic and alkaline artificial sweat solution and immersed at room temperature for 30 minutes, and then attached to a sweat test machine and a load of about 12.5 kPa (about 45 N for a 6 cm × 6 cm test piece). I applied. After the sweat tester was treated with a dryer at 37 ° C. ± 2 ° C. for 4 hours, the composite test piece was removed from the sweat tester and dried, and the discoloration of the test piece and the degree of contamination of the attached white cloth were determined.
(3) JIS L 0842 Dye Fastness Test Method for Ultraviolet Carbon Arc Lamp Light A test was performed in accordance with the third exposure method. The test piece was sandwiched between cardboards with small windows and attached to the sample holder. Using an ultraviolet carbon arc lamp, light was applied until the quaternary blue scale faded standardly. After irradiation, the test piece was taken out and judged by comparing the color difference between the portion exposed to light and the portion not exposed to light with a standardly faded blue scale.
(4) The test was carried out in accordance with the dyeing fastness test method for JIS L 0849 friction. Specifically, two types of tests, a dry test and a wet test, were performed using a friction tester type II. In the case of type II, a dry or wet white cotton cloth is attached to the tip of the friction element, and the specimen is rubbed back and forth 100 times at a speed of 30 reciprocations per minute with a load of 2 N over 10 cm of the test piece. The degree was judged.
(5) The color crying test method was conducted according to the Daimaru method. For the preparation of the sample, in the case of a printed pattern or a striped pattern fabric, a long and cut piece was used as a test piece. One end of the test piece was immersed 2 cm in a beaker containing a 0.05% nonionic surfactant solution. After being left for 2 hours, the beaker was removed and air-dried, and the degree of contamination of the attached white cloth was determined.

[Surface dyeability of fabric]
The surface dyeability of the woven fabric was determined by the quality of the woven fabric viewed from the back side of the woven fabric (whether the weirs are conspicuous visually). The evaluation criteria are as follows. The average value of the evaluation of three judges was adopted.
5 points: The weft of the woven fabric is not recognized, and the quality is satisfactory 4 points: The weft of the woven fabric is slightly recognized, 3 points are of good quality ... There is a weave of the woven fabric, but can be purchased 2 points: There are many weaves in the woven fabric, and the merchantability is low.

[Water retention rate of fabric]
A fabric with a known dry mass (mass Ag) was cut to a size of 10 cm × 10 cm in a bias shape, placed in a metal container, added with 3 L of distilled water, and allowed to stand immersed for 1 hour while maintaining the temperature at 25 ° C. Subsequently, a test piece was set in a centrifuge (LC-100, manufactured by Tommy Kogyo Co., Ltd.), the weight (Bg) after dehydration treatment was performed at 2000 rpm for 3 minutes, and the water retention rate was calculated from the formula [1]. did. The absolutely dry mass means that the fabric cut into a size of 10 cm × 10 cm in a bias shape was left in a hot air dryer (Yamato Kagaku, DX400, set temperature 105 ° C.) for 2 hours, and then blue silica gel was added. It is a value obtained by cooling with a desiccator for 2 hours and then measuring the mass of the fabric.
Water retention rate (%) = (B−A) / A × 100 [1]

[Dimensional change rate of fabric]
JIS L-1096 Dimensional change of woven fabric The dimensional change rate of the woven fabric was measured according to the G method. Specifically, three pairs of marks are provided at intervals of 20 cm in the warp direction and the weft direction, and the length of the measurement section before and after processing is measured as the measurement section, and the dimensional change rate is obtained from the calculation formula [2]. .
Dimensional change rate (%) = (average value of measurement length after treatment−average value of measurement length before treatment) / average value of measurement length before treatment) × 100 [2]

Tables 1 and 2 show various evaluation results of the fabric products and dyed fabric products obtained in the above Examples and Comparative Examples, respectively.

  As is apparent from Tables 1 and 2, the textile products of Examples given specific mechanical properties by cross-linking have practically sufficient W & W properties. Further, by subjecting the fabric products of the examples to a dyeing treatment, a high-quality dyed fabric product excellent in dyeability, dyeing fastness and surface dyeability was obtained. On the other hand, the textile products of Comparative Example 1 and Comparative Example 3 have excellent W & W properties, but have insufficient dyeability when subjected to a dyeing treatment. Moreover, although the textile products of the comparative example 2, the comparative example 4, and the comparative example 5 show the dyeability etc. which were excellent when it used for the dyeing | staining process, W & W property is inadequate. From these results, it is possible to impart practically sufficient W & W properties while maintaining the dyeability of the original (before crosslinking) by applying a crosslinking treatment so that the mechanical properties are within a predetermined range. I understand. In addition, in the dyed fabric product of the example, the dimensional change and the hue change were suppressed as compared with the dyed fabric product obtained by performing the crosslinking treatment after the dyeing treatment. From this, the dyed textile product obtained by dyeing the textile product of the present invention is excellent in terms of hue reproducibility and original pattern dimension retention, and is advantageous from the viewpoint of giving an elaborate color pattern. I know that there is.

  The textile product of the present invention can be suitably used for various textile products such as handkerchiefs.
