Description
本発明は、防しわ性と染色性とに優れた織物製品に関する。 The present invention relates to a textile product excellent in wrinkle resistance and dyeability.
セルロース繊維を含む織地は、一般に、洗濯によって生じたしわが残りやすく、ウォッシュアンドウェアー性(W&W性)が低い。よって、従来、W&W性を改善するために、セルロース架橋剤を用いてセルロース分子相互を化学架橋する方法が用いられてきた。 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.
一方、セルロース繊維を含む織地にW&W性と色模様との両方を付与する場合において、織地を化学架橋した後に染色すると、発色しなかったり、色相が不均一になる等の問題がある。そのため、先染糸を用いて製織した織地を化学架橋する方法や織地を染色した後に化学架橋する方法が用いられている。しかしながら、これらの方法には、化学架橋によって色相が変化する、織地の寸法変化に伴って模様が変形する等の問題がある。さらに、小ロット毎(例えば1枚毎)に好みの模様を取り入れるには経済的に高価である。 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).
これに対し、化学架橋を伴わない形態安定方法によって後工程での染色性を高める方法(特許文献1)や化学架橋してW&W性が改善された絹織物にインクジェット捺染する方法(特許文献2)が提案されている。しかしながら、特許文献1に記載の方法では、W&W性の付与が不十分である。また、特許文献2の方法は、絹織物に対しては有効であるが、セルロース繊維を含む織地に適用してもW&W性と染色性とを両立できない。 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.
本発明は上記問題を解決するためになされたものであり、その目的は、セルロース系繊維を用いて製織された織地を含む織物製品であって、実用上十分なW&W性を有し、かつ、染色処理に供された場合に優れた染色性を示す織物製品を提供することにある。 The present invention has been made in order to solve the above problems, and the object thereof is a woven product including a woven fabric woven using cellulosic fibers, and has a practically sufficient W & W property, and An object of the present invention is to provide a textile product that exhibits excellent dyeability when subjected to a dyeing treatment.

以下、第1の実施形態および第2の実施形態に関して詳述する。 Hereinafter, the first embodiment and the second embodiment will be described in detail.
[A−1.第1の実施形態]

[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.
上記セルロース系繊維に含有されるセルロース繊維としては、用途等に応じて任意の適切なセルロース繊維が用いられ得る。セルロース繊維の具体例としては、綿(例えば、短繊維綿、中繊維綿、長繊維綿、超長綿、超・超長綿)、麻、竹、こうぞ、みつまた、バナナ、被嚢類等の植物性および動物性の天然セルロース繊維;レーヨン繊維(例えば、ビスコースレーヨン、銅アンモニアレーヨン)等の再生セルロース繊維;アセテート繊維(例えば、ビスアセテート、トリアセテート)等の半再生セルロース繊維;等が挙げられる。なかでも、吸水性、風合い、および物性に優れた織物製品が得られ得ることから、綿、麻、およびレーヨンが好ましく用いられ得る。セルロース繊維は、単独で、または2種以上を組み合わせて用いてもよい。 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.
上記セルロース系繊維において、上記セルロース繊維と組み合わせて用いられ得る他の繊維としては、用途等に応じて任意の適切な繊維が用いられ得る。具体例としては、ポリエステル繊維、ポリアミド繊維、ポリウレタン繊維、ポリエチレン繊維、ポリオレフィン繊維、ポリイミド繊維、ポリ乳酸繊維等が挙げられる。ポリエステル繊維を上記セルロース繊維と組み合わせて用いることにより、W&W性の向上効果が得られ得る。ポリアミド繊維、ポリウレタン繊維等を上記セルロース繊維と組み合わせて用いることにより、織地の緯方向の引張硬さ(LT)や緯方向の引張回復性(RT)を好ましい範囲に調整し得る。当該他の繊維は、単独で、または2種以上を組み合わせて用いてもよい。 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.
上記セルロース系繊維は、目的に応じて任意の適切な形態であり得る。具体的には、原糸(未加工糸)、仮撚糸、染色糸等の形態が挙げられる。また、単糸、合撚糸、カバリングヤーン等の形態が挙げられる。また、当該セルロース系繊維が2種以上の繊維を含む場合、当該2種以上の繊維は、例えば、混紡糸、混撚糸等の形態であり得る。これらの形態は、単独でまたは2種以上組み合わせて採用され得る。 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.
上記セルロース系繊維の繊度は、英式綿番手で30〜80番手である。繊度が30番手未満であると、繊維が太いために織地が硬くなるという問題がある。一方、繊度が80番手を超えると、繊維が細いために織地の引張強力、引裂強力等が低くなる、製造コストが高くなる等の問題がある。例えば、本発明の織物製品を婦人用ハンカチとして用いる場合の繊度は、好ましくは60〜80番手である。また、ブラウスとして用いる場合の繊度は、好ましくは40〜80番手である。なお、繊度が40番手である糸としては、40番手の単糸、80番手の単糸からなる双糸等を用いることができる。 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.
上記織地は、必要に応じて、上記セルロース系繊維に加えて他の繊維を経糸および/または緯糸として用いて製織(いわゆる、交織り)されてもよい。該他の繊維としては、上記セルロース系繊維においてセルロース繊維と混紡され得る他の繊維と同様の繊維が挙げられる。該他の繊維の繊度は、上記セルロース系繊維と同様である。他の繊維を用いて交織りする場合、織地全体におけるセルロース繊維の含有量は、好ましくは60質量%以上であり、より好ましくは70質量%〜100質量%、さらに好ましくは80質量%〜100質量%、さらにより好ましくは90質量%〜100質量%である。 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.
上記織地の織組織は、平織である。なかでも、ブロード、ローン、ガーゼ等の平織組織が好ましい。例えば、ブロードは、地合いが密で光沢を持つ点で好ましい。また、ローンは、ソフトな手触りでありながら麻のような感触を持つ点で好ましい。 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.
上記織地の織密度は、経糸密度が100〜200本/インチであり、緯糸密度が50〜150本/インチである。織密度が当該範囲より粗いと、糸同士の隙間の多い織地となるので、織地の強度が小さい場合がある。また、例えばハンカチとして用いた場合に、吸水性等が劣る場合がある。一方、織密度が当該範囲より密であると、糸同士の隙間が少なくなるので、風合いが硬くなる、張りが強くなる、織地が重たくなる等の場合がある。所望の用途に応じた性能(例えば、吸水性、速乾性、柔らかさ)、織地の強度、厚さおよび重さ等の観点から、好ましい経糸密度は110〜150本/インチである。同様の観点から、好ましい緯糸密度は60〜80本/インチである。経糸密度と緯糸密度とは、互いに同じであっても、異なっていてもよい。なお、上記織地の織密度は、後述する架橋処理を経て得られる織物製品における織地の織密度である。よって、上記織地の織密度は、製織時の織密度とは異なる場合がある。 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.
上記織地には、セルロース架橋剤を用いた架橋処理が施されている。その結果、セルロース繊維が架橋されて、織地に後述する所定の力学物性が付与される。なお、架橋処理についてはB項において詳述する。 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.
上記織地の緯方向の引張硬さ(LT)は、0.82〜0.97であり、好ましくは0.83〜0.96、より好ましくは0.84〜0.96である。引張硬さが0.82未満であると、W&W性が低下したり、染色時ににじみが激しくなる、表面染色性が低下する等によりインクジェット捺染のような精巧な染色が難しくなる場合がある。一方、引張硬さが0.97を超えると、W&W性は向上し得るが、染色性が低下する、織地の風合いが硬くなる、物性が低下する場合等がある。 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.
上記織地の緯方向の伸び(EMT)は、3〜12%であり、好ましくは3〜11%、より好ましくは3〜10%である。伸びが3%未満であると、染色性が低下する、織地の風合いが硬くなる、物性が低下する場合等がある。一方、伸びが12%を超えると、W&W性が低下したり、染色時ににじみが激しくなる、表面染色性が低下する等によりインクジェット捺染のような精巧な染色が難しくなる場合がある。 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.
上記織地の緯方向の引張回復性(RT)は、好ましくは45〜75%、より好ましくは50〜73%、さらに好ましくは50〜70%である。引張回復性が45%未満であると、W&W性が低下したり、染色時ににじみが激しくなる、表面染色性が低下する等によりインクジェット捺染のような精巧な染色が難しくなる場合がある。一方、引張回復性が75%を超えると、W&W性は向上し得るが、染色性が低下する、織地の物性が低下する場合等がある。 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.
上記所定の力学物性を有する織地は、実用上十分なW&W性を有し、かつ、染色処理に供した場合に優れた染色性を示す。なお、上記引張硬さ(LT)、伸び(EMT)および引張回復性(RT)は、繊維製品の風合い測定に使用されるKES測定で定義される力学物性値である。これらの物性値は、架橋処理条件を適切に設定することによって所望の範囲内に調整することができる。具体的には、架橋剤の使用量を好適な範囲で多くすることにより、引張硬さおよび引張回復性が増大され得、また、伸びが抑制され得る。 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.
上記織地の見掛け比重は、例えば0.4〜0.9g/cm3であり、好ましくは0.5〜0.8g/cm3であり、より好ましくは0.5〜0.7g/cm3である。このような見掛け比重であれば、W&W性が良好である。また、織物製品を染色処理に供した場合に均一で良好な発色性が得られ得る。見掛け比重は、織密度、繊度、架橋剤の付着量等を適切に設定することによって所望の範囲に調整され得る。 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.
上記織地の保水率は、好ましくは15〜30%であり、より好ましくは19〜28%であり、さらに好ましくは20〜27%である。このような保水率であれば、W&W性が良好である。また、織物製品を染色処理に供した場合に均一で良好な発色性が得られ得る。 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.
上記織地の引裂強力は、例えば200cN以上であり、好ましくは500cNより高く、より好ましくは600cNより高い。引裂強力が200cN未満であると、使用時または洗濯時に織物製品に破れや裂けが発生し易くなる傾向にある。 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.
第1の実施形態における織物製品は、任意の繊維製品であり得る。具体例としては、ハンカチ、タオル、シーツ、カバー、カーテン、マット、衣服等が挙げられる。 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.第2の実施形態]
以下、本発明の第2の実施形態に関して、第1の実施形態と共通する点(セルロース系繊維の構成、架橋構造の有無、織地の保水率および引裂強力等)については説明を省略し、主として異なる点について説明する。
[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.
上記セルロース系繊維の繊度は、英式綿番手で40〜100番手である。繊度が40番手未満であると、繊維が太いために織地が硬くなるという問題がある。一方、繊度が100番手を超えると、繊維が細いために織地の引張強力、引裂強力等が低くなる、製造コストが高くなる等の問題がある。例えば、本発明の織物製品を婦人用ハンカチとして用いる場合の繊度は、好ましくは60〜100番手である。また、ブラウスとして用いる場合の繊度は、好ましくは40〜80番手である。なお、繊度が40番手である糸としては、40番手の単糸、80番手の単糸からなる双糸等を用いることができる。 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.
上記織地の織組織としては、平織以外の任意の適切な織組織が採用され得る。例えば、朱子織(サテン)、綾織、ドビー織等が挙げられる。これらの織組織によれば、多様なデザインを有する織物製品が得られ得る。例えば、朱子織は、光沢に富み、滑りの良い滑らかな感触を与える点で好ましく、織密度を粗くすることにより、軽量で柔らかく様々なデザインの織物製品が得られ得る。 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.
上記織地の織密度は、経糸密度が120〜240本/インチであり、緯糸密度が60〜170本/インチである。織密度が当該範囲より粗いと、糸同士の隙間の多い織地となるので、織地の強度が小さい場合がある。また、例えばハンカチとして用いた場合に、吸水性等が劣る場合がある。一方、織密度が当該範囲より密であると、糸同士の隙間が少なくなるので、風合いが硬くなる、張りが強くなる、織地が重たくなる等の場合がある。所望の用途に応じた性能(例えば、吸水性、速乾性、柔らかさ)、織地の強度、厚さおよび重さ等の観点から、好ましい経糸密度は130〜170本/インチである。同様の観点から、好ましい緯糸密度は70〜100本/インチである。経糸密度と緯糸密度とは、互いに同じであっても、異なっていてもよい。なお、上記織地の織密度は、後述する架橋処理を経て得られる織物製品における織地の織密度である。よって、上記織地の織密度は、製織時の織密度とは異なる場合がある。 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.
上記織地の緯方向の引張硬さ(LT)は、0.54〜0.78であり、好ましくは0.55〜0.76、より好ましくは0.55〜0.75である。引張硬さが0.54未満であると、W&W性が低下したり、染色時ににじみが激しくなる、表面染色性が低下する等によりインクジェット捺染のような精巧な染色が難しくなる場合がある。一方、引張硬さが0.78を超えると、W&W性は向上し得るが、染色性が低下する、織地の風合いが硬くなる、物性が低下する場合等がある。 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.
上記織地の緯方向の伸び(EMT)は、4〜17%であり、好ましくは4〜16%、より好ましくは4〜15%である。伸びが4%未満であると、染色性が低下する、織地の風合いが硬くなる、物性が低下する場合等がある。一方、伸びが17%を超えると、W&W性が低下したり、染色時ににじみが激しくなる、表面染色性が低下する等によりインクジェット捺染のような精巧な染色が難しくなる場合がある。 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.
上記織地の緯方向の引張回復性(RT)は、45〜75%、好ましくは45〜73%、より好ましくは45〜70%である。引張回復性が45%未満であると、W&W性が低下したり、染色時ににじみが激しくなる、表面染色性が低下する等によりインクジェット捺染のような精巧な染色が難しくなる場合がある。一方、引張回復性が75%を超えると、W&W性は向上し得るが、染色性が低下する、織地の物性が低下する場合等がある。 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.
上記織地の見掛け比重は、例えば0.2〜0.7g/cm3であり、好ましくは0.3〜0.6g/cm3であり、より好ましくは0.4〜0.5g/cm3である。このような見掛け比重であれば、W&W性が良好である。また、織物製品を染色処理に供した場合に均一で良好な発色性が得られ得る。見掛け比重は、織密度、繊度、架橋剤の付着量等を適切に設定することによって所望の範囲に調整され得る。 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.

上記エポキシ化合物としては、分子中に2個以上の反応性官能基を有するものが好ましく、当該反応性官能基はグリシジルエーテル基またはクロルヒドリン基であることが好ましい。具体的には、例えば、エチレングリコールジグリシジルエーテル、ポリエチレングリコールジグリシジルエーテル等のエチレングリコール系や、プロピレングリコールジグリシジルエーテル、ポリプロピレングリコールジグリシジルエーテル等のプロピレングリコール系の分子中に2個の官能基を有するもの、グリセロールグリシジルエーテル等の3個以上の官能基を持つエポキシ系架橋剤等が挙げられる。また、エポキシ変性シリコーンとして、セルロースの水酸基と直接反応するエポキシ基を持つシリコーン誘導体も使用することができる。エポキシ基にはグリシジルタイプのものと脂環式タイプのものとがあるが、いずれのタイプでも構わない。これらは単独でも混合系で使用しても構わない。 As said epoxy compound, what has a 2 or more reactive functional group in a molecule | numerator is preferable, and it is preferable that the said reactive functional group is a glycidyl ether group or a chlorohydrin group. Specifically, for example, two functional groups in a propylene glycol-based molecule such as ethylene glycol diglycidyl ether or polyethylene glycol diglycidyl ether, or propylene glycol diglycidyl ether or polypropylene glycol diglycidyl ether.

上記架橋剤のなかでも、エチレン尿素型の環状尿素化合物および分子の両末端にエポキシ基を有するエポキシ化合物が好ましく用いられ得、分子の両末端にエポキシ基を有するエポキシ化合物であって、エポキシ基間の分子量(架橋後における架橋点間分子量に相当)が40〜200であるエポキシ化合物がより好ましく用いられ得る。これらの環状尿素化合物およびエポキシ化合物によれば、染料がセルロースの染着座席まで到達可能な空間を有する架橋構造(例えば、架橋密度や架橋点間距離)が好適に形成され得るので、W&W性の付与後の染色性が向上され得る。特に、上記エポキシ化合物は、セルロースとの親和性がやや低いため、セルロース系繊維の内部ではなく表面近傍に架橋構造を形成し易く、その結果、織地が過度に疎水化されることなく、染料の運び手である水分が繊維内部まで浸透しやすくなると推測される。 Among the above crosslinking agents, an ethylene urea type cyclic urea compound and an epoxy compound having an epoxy group at both ends of the molecule can be preferably used, and an epoxy compound having an epoxy group at both ends of the molecule, An epoxy compound having a molecular weight of 40 to 200 (corresponding to the molecular weight between crosslinking points after crosslinking) can be used more preferably. 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.
エチレン尿素型の環状尿素化合物としては、ジメチロールエチレン尿素、ジメチロールジヒドロキシエチレン尿素、ジメチルジヒドロキシエチレン尿素等が挙げられる。また、分子の両末端にエポキシ基を有するエポキシ化合物としては、ジグリシジルエーテル、エチレングリコールジグリシジルエーテル、ジエチレングリコールジグリシジルエーテル、トリエチレングリコールジグリシジルエーテル、ポリエチレングリコールジグリシジルエーテル、グリセリンジグリシジルエーテル、ブタンジオールジグリシジルエーテル等が挙げられる。 Examples of the ethylene urea type cyclic urea compound include dimethylol ethylene urea, dimethylol dihydroxy ethylene urea, dimethyl dihydroxy ethylene urea and the like.

上記架橋処理においては、一般に、上記架橋剤は、水等に溶解または分散させた架橋処理液として用いられる。架橋処理液中の架橋剤の固形分濃度(2種以上の架橋剤を用いる場合はその合計濃度)は、架橋剤の種類等に応じて適切に設定され得る。架橋処理液の織地への付与率(織地中に含まれる架橋処理液重量/架橋処理液付与前の織地の重量×100)を70%と仮定した場合、架橋処理液中の架橋剤の固形分濃度は、例えば2〜33質量%であり得る。より具体的には、架橋剤として、エチレン尿素型の環状尿素化合物を用いる場合、織地に上記所定の力学物性を付与して、染色性を維持しつつW&W性が得られる架橋構造を形成する観点から、架橋処理液中の架橋剤の固形分濃度は、好ましくは2〜15質量%、より好ましくは2〜13質量%、さらに好ましくは2〜11質量%である。また、架橋剤として、分子の両末端にエポキシ基を有するエポキシ化合物を用いる場合、織地に上記所定の力学物性を付与して、染色性を維持しつつW&W性が得られる架橋構造を形成する観点から、架橋処理液中の架橋剤の固形分濃度は、好ましくは3〜33質量%、より好ましくは4〜30質量%、さらに好ましくは5〜30質量%である。なお、架橋処理液の織地への付与率が70%と異なる場合は、架橋処理液の織地への付与率の変化率に反比例させて、上述した架橋処理液中の架橋剤の固形分濃度を増減すればよい(例えば、該付与率が35%の場合、架橋処理液中の架橋剤の濃度は、4〜66質量%であり得る)。 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%).

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.
上記架橋処理液には、必要に応じて、セルロースと架橋剤との反応を円滑に進めるための助剤を添加することができる。助剤は、架橋剤とセルロースの反応を促進させたり、架橋生成反応においても反応を均一に進めるといった反応溶媒としての作用、更にはセルロースを膨潤させる作用等を有するものである。当該助剤としては、例えば、グリセリン、エチレングリコール、ポリエチレングリコール、ポリプロピレングリコール等の多価アルコール類、エチレングリコールモノエチルエーテル、ジエチレングリコールモノエチルエーテル、エチレングリコールモノメチルエーテル、ジエチレングリコールモノメチルエーテル、ジエチレングリコールモノブチルエーテル等のエーテルアルコール類、ジメチルホルムアミド、モルホリン、2−ピロリドン、ジメチルアセトアミド、N−メチルピロリドン等の含窒素溶媒類、酢酸エチル、酢酸イソプロピル、酢酸ブチル、酢酸アミル、酢酸エチレングリコールモノメチルエーテル、酢酸エチレングリコールモノエチルエーテル、γ−ブチロラクトン等のエステル類等が挙げられる。これらは1種単独でまたは2種以上を混合して使用することができる。 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.

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.

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.

In addition, the entire fabric was slightly yellowed due to the crosslinking treatment.
上記実施例および比較例で得られた織物製品および染色織物製品の各種評価結果をそれぞれ表1および表2に示す。
表1および表2から明らかなように、架橋によって特定の力学物性を付与された実施例の織物製品は、実用上十分なW&W性を有している。さらに、実施例の織物製品を染色処理に供することにより、染色性、染色堅牢性および表面染色性に優れた高品位の染色織物製品が得られた。一方、比較例1および比較例3の織物製品は、優れたW&W性を有するものの、染色処理に供した場合の染色性が不十分である。また、比較例2、比較例4および比較例5の織物製品は、染色処理に供した場合に優れた染色性等を示すものの、W&W性が不十分である。これらの結果から、力学的物性が所定の範囲内になるように架橋処理を施すことにより、本来の(架橋前の)織地の染色性を維持しつつ、実用上十分なW&W性を付与できることが分かる。また、実施例の染色織物製品は、染色処理後に架橋処理を施して得られる染色織物製品に比べて、寸法変化および色相変化が抑制されていた。このことから、本発明の織物製品を染色して得られる染色織物製品は、色相の再現性や元柄の寸法保持性の点で優れており、精巧な色柄模様の付与の観点から有利であることがわかる。 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.
本発明の織物製品は、ハンカチ等の種々の繊維製品に好適に用いられ得る。 The textile product of the present invention can be suitably used for various textile products such as handkerchiefs.
