If the fabric does not contain an organic fiber yarn that has been twisted with such a twisting coefficient, it is not preferable because sufficient quick drying properties cannot be obtained. However, the twist coefficient is calculated by the following formula.
Twist factor = T × (D) 1/2
Here, T is the number of twists (T / m), and D is the total fineness (dtex) of the organic fiber yarn.
前記有機繊維の種類としては、ポリエステル繊維、アセテート繊維、ポリアミド繊維、アラミド繊維、炭素繊維、綿や羊毛などの天然繊維などいずれでもよい。なかでも、ポリエチレンテレフタレートやポリトリメチレンテレフタレート、ポリブチレンテレフタレート、ポリ乳酸、ステレオコンプレックスポリ乳酸、第３成分を共重合させたポリエステルなどからなるポリエステル繊維が、速乾性だけでなくリサイクル性にも優れ好ましい。なお、かかるポリエステルとしては、マテリアルリサイクルまたはケミカルリサイクルされたポリエステルであってもよい。さらには、特開２００４−２７００９７号公報や特開２００４−２１１２６８号公報に記載されているような、特定のリン化合物およびチタン化合物を含む触媒を用いて得られたポリエステルでもよい。該ポリマー中には、本発明の目的を損なわない範囲内で必要に応じて、微細孔形成剤、カチオン染料可染剤、着色防止剤、熱安定剤、蛍光増白剤、艶消し剤、着色剤、吸湿剤、無機微粒子が１種または２種以上含まれていてもよい。 The organic fiber may be any of polyester fiber, acetate fiber, polyamide fiber, aramid fiber, carbon fiber, natural fiber such as cotton and wool. Among them, a polyester fiber made of polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, stereocomplex polylactic acid, polyester copolymerized with the third component, etc. is preferable because it is excellent not only in quick drying but also in recyclability. . The polyester may be material recycled or chemically recycled polyester. Furthermore, the polyester obtained using the catalyst containing the specific phosphorus compound and titanium compound which are described in Unexamined-Japanese-Patent No. 2004-270097 and 2004-21268 may be sufficient. In the polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent may be added as necessary within the range not impairing the object of the present invention. 1 type, or 2 or more types of an agent, a hygroscopic agent, and inorganic fine particles may be contained.
前記有機繊維の繊維形態は、長繊維（マルチフィラメント）、短繊維（紡績糸）いずれでもよいが、長繊維（マルチフィラメント）が好ましい。単繊維の断面形状も特に限定されず、丸、三角、扁平、中空など公知の断面形状でよい。また、通常の空気加工、仮撚捲縮加工が施されていてもさしつかえない。特に、有機繊維糸条に仮撚捲縮加工が施されていると布帛が嵩高となるため保温性が向上し好ましい。 The fiber form of the organic fiber may be either a long fiber (multifilament) or a short fiber (spun yarn), but a long fiber (multifilament) is preferable. The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape. In addition, normal air processing and false twist crimping may be applied. In particular, it is preferable that the organic fiber yarn is subjected to false twist crimping because the fabric becomes bulky and thus the heat retention is improved.
前記有機繊維において、単糸繊維繊度、総繊度、フィラメント数は特に限定されないが、ソフトな風合いを得る上で、それぞれ単糸繊維繊度４．０ｄｔｅｘ以下（好ましくは０．１〜４．０ｄｔｅｘ）、総繊度３０〜２００ｄｔｅｘ、フィラメント数３０本以上（より好ましくは６０本以上、さらに好ましくは６０〜２００本）の範囲内であることが好ましい。 In the organic fiber, the single fiber fineness, the total fineness, and the number of filaments are not particularly limited, but for obtaining a soft texture, the single fiber fineness is 4.0 dtex or less (preferably 0.1 to 4.0 dtex), It is preferable that the total fineness is 30 to 200 dtex and the number of filaments is 30 or more (more preferably 60 or more, and further preferably 60 to 200).
前記布帛の布帛組織は特に限定されず織物、編物、不織布などいずれでもよい。なかでも、引裂き強力の強さの点で織物または編物が好ましい。特に織物が好ましい。織物組織としては、平織、綾織、朱子織等の三原組織、変化組織、たて二重織、よこ二重織等の片二重組織、たてビロードなどが例示されるがこれらに限定されない。層数は単層でもよいし、２層以上の多層でもよい。特に、下記式により定義されるカバーファクターＣＦが２０００〜４５００の織物であると、前記のような大きな目付けが得られやすく好ましい。なお、以上のような布帛は常法により製造することが可能である。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
［ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。］
The fabric structure of the fabric is not particularly limited and may be a woven fabric, a knitted fabric, a nonwoven fabric, or the like. Of these, a woven fabric or a knitted fabric is preferable in terms of tear strength. A woven fabric is particularly preferable. Examples of the fabric structure include, but are not limited to, a three-layer structure such as plain weave, twill weave, and satin weave, a change structure, a single double structure such as a vertical double weave and a horizontal double weave, and a vertical velvet. The number of layers may be a single layer or a multilayer of two or more layers. In particular, a fabric having a cover factor CF defined by the following formula of 2000 to 4500 is preferable because large fabric weight as described above is easily obtained. In addition, the above fabrics can be manufactured by a conventional method.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
[DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm). ]
本発明の速乾性布帛は、前記の布帛に撥水加工を施したものである。かかる布帛は、例えば、以下の製造方法により製造することができる。
まず、前記のような有機繊維糸条を用意し、該有機繊維糸条に撚係数５０００以上の撚糸を施した後、該有機繊維糸条を用いて、目付けが１５０ｇ／ｍ２以上の布帛を製編織する。その際、前記有機繊維糸条だけで布帛を構成することが最も好ましいが、布帛重量に対して５０重量％以下であれば、他の有機繊維糸条（例えば、撚係数５０００未満のポリエステル繊維糸条など）が含まれていてもよい。
The quick-drying fabric of the present invention is obtained by subjecting the fabric to a water repellent finish. Such a fabric can be manufactured, for example, by the following manufacturing method.
First, an organic fiber yarn as described above is prepared, and after twisting the organic fiber yarn with a twist coefficient of 5000 or more, a fabric having a basis weight of 150 g / m 2 or more is formed using the organic fiber yarn. Weaving and weaving. At that time, it is most preferable that the fabric is constituted only by the organic fiber yarn, but if it is 50% by weight or less based on the weight of the fabric, other organic fiber yarn (for example, polyester fiber yarn having a twist coefficient of less than 5000). Article etc.) may be included.
次いで、該布帛に撥水加工を施す。ここで、撥水加工の際に用いる撥水剤としてはフッ素系（例えば、旭硝子（株）製、アサヒガードＬＳ−３１７）、シリコン系、パラフィン系、エチレン尿素系、脂肪酸系などの撥水剤を挙げることができるが、洗濯耐久性の点からフッ素系、シリコン系の撥水剤を使用するのが好ましい。 Next, the fabric is subjected to water repellent finish. Here, as the water repellent used in the water repellent processing, water-repellent such as fluorine-based (for example, Asahi Guard LS-317 manufactured by Asahi Glass Co., Ltd.), silicon-based, paraffin-based, ethylene urea-based, fatty acid-based, etc. In view of washing durability, it is preferable to use a fluorine-based or silicon-based water repellent.
また、撥水加工としては通常のものでよいが、特許第３１３３２２７号公報や特公平４−５７８６号公報に記載された方法が好適である。すなわち、撥水剤として前記の撥水剤を使用し、必要に応じてメラミン樹脂、触媒を混合して撥水剤の濃度が２〜１５重量％程度の加工剤とし、ピックアップ率５０〜１００％程度で、該加工剤を用いて布帛の表面を処理する方法である。加工剤で布帛の表面を処理する方法としては、パッド法、スプレー法などが例示され、なかでも、加工剤を布帛内部まで浸透させる上でパッド法が最も好ましい。なお、前記ピックアップ率とは、加工剤の布帛（加工剤付与前）重量に対する重量割合（％）である。 The water repellent finish may be a normal one, but the methods described in Japanese Patent No. 3133227 and Japanese Patent Publication No. 4-5786 are suitable. That is, the above-mentioned water repellent is used as a water repellent, and a melamine resin and a catalyst are mixed as necessary to obtain a processing agent having a water repellent concentration of about 2 to 15% by weight, and a pickup rate of 50 to 100%. This is a method of treating the surface of the fabric with the processing agent. Examples of the method of treating the surface of the fabric with the processing agent include a pad method and a spray method, and among them, the pad method is most preferable for allowing the processing agent to penetrate into the fabric. In addition, the said pick-up rate is a weight ratio (%) with respect to the fabric (before processing agent provision) weight of a processing agent.

かくして得られた布帛は、目付けが１５０ｇ／ｍ２以上と目付けが大きいにもかかわらず、極めて優れた速乾性を呈する。その理由は、布帛に含まれる有機繊維糸条に撚係数５０００以上の撚糸が施されており、かつ布帛に撥水加工が施されているのでこれらの相乗作用によって、水分が布帛内部にはいりにくく、布帛内部にはいった場合においても、脱水時の水切れが良くなっているためでないか、と推定している。 The fabric thus obtained exhibits extremely excellent quick-drying properties although the basis weight is as large as 150 g / m 2 or more. The reason is that the organic fiber yarns contained in the fabric are twisted with a twist coefficient of 5000 or more, and the fabric is water-repellent, so that it is difficult for moisture to enter the fabric due to their synergistic action. Even in the case of entering the fabric, it is presumed that the drainage during dehydration is better.
ここで、速乾性としては、下記式で定義する洗濯脱水抱水率が５０％以下（より好ましくは２０％以下、特に好ましくは５〜２０％）であることが好ましい。
洗濯脱水抱水率（％）＝（Ｗ１−Ｗ０）／Ｗ０×１００
ただし、Ｗ０は試料（タテ４０ｃｍ、ヨコ４０ｃｍ）を乾燥後、温度２０℃、相対湿度６５％の環境に２４時間放置した後の重量（ｇ）であり、Ｗ１は当該試料を洗濯脱水した後の重量（ｇ）である。また、洗濯脱水は、試料（タテ４０ｃｍ、ヨコ４０ｃｍ）を、ＪＩＳ−Ｃ−９６０６に規定する遠心式脱水装置付きの家庭用電気洗濯機を用い、ＪＩＳ−Ｌ−０２１７の１０３法に記載の試験方法で行う。すなわち、洗液温度は４０℃とし、標準使用量となる割合で合成洗剤を溶解し、浴比が１対３０になるように試料を投入する。この状態で５分間処理した後に運転を止め、試料を脱水機で脱水し、洗濯液を３０℃以下の新しい水に替えて２分間すすぎを行う。次に試料を脱水し、ふたたび２分間のすすぎを行い、脱水を３分間（通電時間）行った後の重量をＷ１とする。
Here, as quick-drying property, it is preferable that the laundry dehydration water retention rate defined by the following formula is 50% or less (more preferably 20% or less, particularly preferably 5 to 20%).
Washing water dehydration rate (%) = (W1-W0) / W0 × 100
However, W0 is a weight (g) after drying a sample (40 cm in length, 40 cm in width) and leaving it in an environment at a temperature of 20 ° C. and a relative humidity of 65% for 24 hours, and W1 is after the sample is washed and dehydrated. Weight (g). In addition, laundry dehydration is a test described in the method 103 of JIS-L-0217 using a household electric washing machine with a centrifugal dehydrator specified in JIS-C-9606 for a sample (length 40 cm, width 40 cm). By the way. That is, the washing temperature is set to 40 ° C., the synthetic detergent is dissolved at a rate corresponding to the standard usage amount, and the sample is introduced so that the bath ratio is 1:30. After processing for 5 minutes in this state, the operation is stopped, the sample is dehydrated with a dehydrator, and the washing liquid is replaced with fresh water of 30 ° C. or lower and rinsed for 2 minutes. Next, the sample is dehydrated, rinsed again for 2 minutes, and the weight after dehydration for 3 minutes (energization time) is defined as W1.

脱水度（％）＝乾燥試験布の重量（ｋｇ）／脱水後の試験布の重量（ｋｇ）×１００
乾燥試験布の重量（ｋｇ）は、試験布を温度２０℃、相対湿度６５％の環境に２４時間放置した後の重量（ｋｇ）であり、脱水後の試験布の重量（ｋｇ）とは、乾燥試験布を試験に先立ち１時間以上水に付けた後、遠心式脱水装置付きの家庭用電気洗濯機を用い、３分間（通電時間）脱水を行った後の重量（ｋｇ）で有る。

At that time, the degree of dehydration was calculated by the following equation. Moreover, the simulated laundry (henceforth a test cloth) as described in the appendix 1 of JIS-C-9606 was used for the test cloth used for a dehydration test.
Dehydration degree (%) = weight of dry test cloth (kg) / weight of test cloth after dehydration (kg) × 100
The weight (kg) of the dried test cloth is the weight (kg) after leaving the test cloth in an environment of a temperature of 20 ° C. and a relative humidity of 65% for 24 hours. The weight (kg) of the test cloth after dehydration is It is the weight (kg) after dehydration for 3 minutes (energization time) using a household electric washing machine equipped with a centrifugal dehydrator after the dry test cloth is dipped in water for 1 hour or more prior to the test.
特に、洗濯２０回後の、洗濯脱水抱水率が５０％以下（より好ましくは５〜５０％）であることが好ましい。ここで、洗濯は、ＪＩＳ−Ｃ−９６０６に規定する遠心式脱水装置付きの家庭用電気洗濯機を用い、ＪＩＳ−Ｌ−０２１７の１０３法に記載の試験方法に準じる洗濯、乾燥を２０回繰返す。すなわち、洗液温度は４０℃とし、標準使用量となる割合で合成洗剤を溶解し、浴比が１対３０になるように試料を投入する。この状態で５分間処理した後に運転を止め、試料を脱水機で脱水し、洗濯液を３０℃以下の新しい水に替えて２分間すすぎを行う。次に試料を脱水し、ふたたび２分間のすすぎを行い、脱水し、直射日光の影響を受けない状態で吊干し又は平干しをする。これを２０回繰返した後、前記の洗濯脱水抱水率を測定する。 In particular, it is preferable that the water dehydration rate after washing 20 times is 50% or less (more preferably 5 to 50%). Here, washing uses a household electric washing machine with a centrifugal dewatering device specified in JIS-C-9606, and repeats washing and drying 20 times in accordance with the test method described in Method 103 of JIS-L-0217. . That is, the washing temperature is set to 40 ° C., the synthetic detergent is dissolved at a rate corresponding to the standard usage amount, and the sample is introduced so that the bath ratio is 1:30. After processing for 5 minutes in this state, the operation is stopped, the sample is dehydrated with a dehydrator, and the washing liquid is replaced with fresh water of 30 ° C. or lower and rinsed for 2 minutes.
