本発明によれば、芯鞘型混繊糸を含み、速乾性だけでなくふくらみのあるソフト風合い
および抗スナッギング性にも優れた速乾性布帛および繊維製品が得られる。
According to the present invention, it is possible to obtain a quick-drying fabric and a textile product that contain a core-sheath type mixed yarn and that are not only quick-drying, but also have an excellent swollen soft texture and anti-snagging properties.
以下、本発明の実施の形態について詳細に説明する。まず、本発明の速乾性布帛は芯鞘型混繊糸を含み、かかる前記混繊糸の芯部および鞘部が仮撚捲縮加工を施されてないマルチフィラメント(「非仮撚加工糸」ということもある。)で構成される。混繊糸の芯部または鞘部に仮撚捲縮加工糸が配されていると、速乾性が低下するおそれがあり好ましくない。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail. First, the quick-drying fabric of the present invention includes a core-sheath type mixed yarn, and the core and sheath of the mixed yarn are multifilaments that are not subjected to false twist crimp processing (“non-false twisted yarn”). It is also called.). If the false-twisted crimped yarn is arranged in the core or sheath of the mixed yarn, the quick-drying property may deteriorate, which is not preferable.
前記混繊糸において、総繊度が50~150dtex(より好ましくは70~130dtex)の範囲内であることが好ましい。混繊糸の総繊度が上記範囲より小さいと、速乾性布帛の密度が小さくなることによりスナッギングが起きやすくなるおそれがある。逆に上記範囲を越えると、速乾性布帛の風合いが硬くなり、目付けも大きくなりすぎるおそれがある。 In the mixed yarn, the total fineness is preferably in the range of 50-150 dtex (more preferably 70-130 dtex). If the total fineness of the mixed yarn is smaller than the above range, the density of the quick-drying fabric becomes low, which may easily cause snagging. Conversely, if the above range is exceeded, the quick-drying fabric may have a hard texture and may have an excessively large basis weight.
また、前記混繊糸の芯部および/または鞘部のフィラメント数としては、20~200本の範囲内であることが好ましい。特に、芯部と鞘部がともに20~200本の範囲内であることが好ましい。 The number of filaments in the core and/or sheath of the mixed yarn is preferably in the range of 20 to 200. In particular, it is preferable that both the core portion and the sheath portion are within the range of 20 to 200.
混繊糸中の鞘部の作用としては、まず肌側の鞘部が発汗した汗を瞬時に吸水・拡散し、芯部に移行させ、同時に、外側の鞘部にも移行・拡散させ、布帛に適度なふくらみとソフト風合いを付加することである。吸水・拡散効果を上げ、ソフト風合いにするためには、鞘部の単繊維繊度は、3.0dtex以下(より好ましくは0.001~1.3dtex)であることが好ましい。鞘部を構成する繊維の断面形状は特に限定されないが、異形断面であることが好ましい。異形断面に関しては、三角、偏平、Y型、W型、十字などのいずれでも良い。特に、吸水性、速乾性、ふくらみのあるソフト風合いの点で、偏平断面が好ましく、フラットな偏平断面より、くびれ部を有する偏平断面がより好ましい。 The function of the sheath in the mixed yarn is to absorb and diffuse perspiration instantaneously from the sheath on the skin side, transfer it to the core, and at the same time, transfer and diffuse it to the outer sheath to create a fabric. It is to add moderate swelling and soft texture to the. In order to increase the water absorption/diffusion effect and provide a soft texture, the single fiber fineness of the sheath is preferably 3.0 dtex or less (more preferably 0.001 to 1.3 dtex). Although the cross-sectional shape of the fiber constituting the sheath is not particularly limited, it preferably has an irregular cross-section. The modified cross section may be triangular, flat, Y-shaped, W-shaped, cross-shaped, or the like. In particular, a flat cross section is preferable in terms of water absorbency, quick drying, and bulging soft texture, and a flat cross section having a constricted portion is more preferable than a flat flat cross section.
一方、芯部の作用としては、肌側の鞘部が吸水・拡散した水分を、毛細管現象を利用して瞬時に吸水・拡散し、外側の鞘部に移行させることである。芯部の単繊維繊度は、吸水性と拡散性の点から、0.5dtex以上であることが好ましく、より好ましくは0.9~2.2dtexの範囲である。単繊維繊度が上記範囲より小さい場合、吸水性、風合は良好となるが、速乾性が不十分となるおそれがある。一方、上記範囲より大きい場合、風合が硬くなり、目的とする速乾性布帛が得られにくくなるおそれがある。芯部を構成する繊維の断面形状は特に限定されず、前記のような異形断面でもよいし丸断面でもよい。 On the other hand, the function of the core part is to instantly absorb and diffuse the water absorbed and diffused by the sheath on the skin side using capillary action, and transfer it to the outer sheath. The single fiber fineness of the core is preferably 0.5 dtex or more, more preferably in the range of 0.9 to 2.2 dtex, from the viewpoint of water absorption and diffusion. If the monofilament fineness is smaller than the above range, the water absorbency and feel will be good, but the quick-drying property may be insufficient. On the other hand, when it is larger than the above range, the feel becomes hard, and it may become difficult to obtain the intended quick-drying fabric. The cross-sectional shape of the fibers constituting the core is not particularly limited, and may be an irregular cross-section as described above or a round cross-section.
前記芯部および/または鞘部に配される繊維を形成するポリマーの種類としては、ポリエステルや脂肪族ポリアミド(ナイロン6、ナイロン66など)が好ましい。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、第3成分を共重合させたポリエステルなどがより好ましく例示される。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。特に艶消し剤がポリマー重量対比0.1重量%以上(より好ましくは0.3~2.0重量%)含まれていると、防透性が向上し好ましい。具体的には、セミダルポリエステル、フルダルポリエステル、カチオン可染性ポリエステルが好ましい。カチオン染料可染剤(エステル形成性スルホン酸金属塩化合物など)がポリエステル中に含まれていると、国際公開第2011/048888号パンフレットに記載されているように酸性処理することで抗菌防臭性が付加され好ましい。 Polyester and aliphatic polyamide (nylon 6, nylon 66, etc.) are preferable as the type of polymer forming the fibers arranged in the core and/or sheath. Among them, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, and polyester obtained by copolymerizing a third component are more preferable examples. Such polyester may be material-recycled or chemical-recycled polyester. Furthermore, polyesters obtained using a catalyst containing a specific phosphorus compound and titanium compound as described in JP-A-2004-270097 and JP-A-2004-211268 may also be used. The polymer may optionally contain a micropore-forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent brightening agent, a matting agent, and a coloring agent, as long as they do not impair the object of the present invention. It may contain one or more kinds of agents, moisture absorbents, and inorganic fine particles. In particular, when the matting agent is contained in an amount of 0.1% by weight or more (more preferably 0.3 to 2.0% by weight) relative to the weight of the polymer, the anti-transparency is improved, which is preferable. Specifically, semi-dull polyester, full-dull polyester, and cationic dyeable polyester are preferred. When a cationic dye dyeing agent (such as an ester-forming sulfonic acid metal salt compound) is contained in polyester, antibacterial deodorant properties can be obtained by acid treatment as described in International Publication No. 2011/048888 pamphlet. Added and preferred.
本発明の速乾性布帛を製造する方法としては、まず、芯部用非仮撚加工糸と鞘部用非仮撚加工糸を用意する。その際、混繊糸を芯鞘構造とする上で、芯部の沸水収縮率は、鞘部の沸水収縮率より大きいことが必要である。例えば、芯部用非仮撚加工糸としては、ポリエステル未延伸糸(UDY)やポリエステル部分配向糸(POY)を冷延伸した糸が、沸水収縮率が大きく好ましい。 As a method for producing the quick-drying fabric of the present invention, first, a non-false-twisted yarn for the core and a non-false-twisted yarn for the sheath are prepared. In this case, the boiling water shrinkage ratio of the core portion must be higher than that of the sheath portion in order to make the mixed yarn have a core-sheath structure. For example, as the non-false-twisted textured yarn for the core, undrawn polyester yarn (UDY) or cold-drawn polyester partially oriented yarn (POY) is preferable because of its high boiling water shrinkage.
次いで、芯部用非仮撚加工糸と鞘部用非仮撚加工糸とを引き揃えて、インターレース加工などの空気混繊法や合撚法により混繊糸を得る。特に、30個/m以上(より好ましくは60~200個/m)のインターレース加工が施されていることが好ましい。 Next, the non-false-twisted yarn for the core and the non-false-twisted yarn for the sheath are aligned to obtain a mixed yarn by an air mixing method such as interlacing or a plied twisting method. In particular, it is preferable that 30 pieces/m or more (more preferably 60 to 200 pieces/m) be interlaced.
かかる混繊糸の熱水収縮率としては、速乾性布帛の抗スナッギング性の点から40%以上(より好ましくは40~60%)であることが好ましい。熱水収縮率が40%より小さいと、染色加工工程で混繊糸が十分に収縮せず、結果として速乾性布帛の密度が低くなる。そのため、速乾性布帛が鋭利なものにひっかかった場合、糸が引き出されてしまい、抗スナッギング性が低下するおそれがある。一方、熱水収縮率が40%より大きいと、染色加工工程で混繊糸の収縮が大きくなるため速乾性布帛の密度が高くなる。その結果、抗スナッギング性は良くなるが風合が硬くなり、速乾性が低下するおそれがある。 The hot water shrinkage of such a mixed yarn is preferably 40% or more (more preferably 40 to 60%) from the viewpoint of anti-snagging properties of the quick-drying fabric. If the hot water shrinkage is less than 40%, the mixed yarn will not shrink sufficiently in the dyeing process, resulting in a low density of the quick-drying fabric. Therefore, when the quick-drying fabric is caught on a sharp object, the thread may be pulled out, resulting in a decrease in anti-snagging properties. On the other hand, if the hot water shrinkage ratio is more than 40%, the shrinkage of the mixed yarn increases during the dyeing process, resulting in a high density of the quick-drying fabric. As a result, the anti-snagging property is improved, but the texture may be hard and the quick-drying property may be deteriorated.
次いで、前記混繊糸を用いて製編織することにより布帛を得た後、適宜、染色加工や吸水加工を施して速乾性布帛を得る。染色加工などの熱履歴により混繊糸に含まれる芯部用繊維が大きく収縮し混繊糸が芯鞘型となる。その際。混繊糸に含まれる芯部と鞘部との糸足差が40%以上(より好ましく50~80%)であることが好ましい。かかる糸足差が40%未満の場合、混繊糸にふくらみが無く、例えば、編物にした際に編みループ間の隙間が大きくなり、引掛りやすくなってスナッギング性が低下するおそれがある。また、混繊糸に含まれる芯部と鞘部との糸足差を40%以上とするには、例えば、芯部用非仮撚加工糸として、ポリエステル未延伸糸(UDY)やポリエステル部分配向糸(POY)を冷延伸した糸を用い、一方、鞘部用非仮撚加工糸としてポリエステルを常法により紡糸・延伸(熱延伸)した延伸糸を用いるとよい。 Next, after the fabric is obtained by knitting and weaving using the mixed yarn, the fabric is appropriately dyed or water-absorbing to obtain a quick-drying fabric. Due to heat history such as dyeing, the core fibers contained in the mixed yarn are greatly shrunk, and the mixed yarn becomes a core-sheath type. that time. It is preferable that the yarn foot difference between the core portion and the sheath portion contained in the mixed yarn is 40% or more (more preferably 50 to 80%). If the yarn foot difference is less than 40%, the mixed yarn does not bulge, and when knitted, for example, the gaps between the knitting loops become large, and there is a risk that the yarn will be easily caught and the snagging property will be reduced. In addition, in order to make the yarn foot difference between the core portion and the sheath portion contained in the mixed yarn to be 40% or more, for example, polyester undrawn yarn (UDY) or polyester partially oriented yarn is used as the non-false-twisted textured yarn for the core portion. A yarn (POY) obtained by cold drawing may be used, and a drawn yarn obtained by spinning and drawing (hot drawing) a polyester by a conventional method may be used as the non-false twisted yarn for the sheath.
なお、芯部と鞘部との糸足差の測定方法としては、例えば、以下の方法が例示される。(糸足差の測定方法1)
まず、混繊糸を用いて混繊糸を用いて筒編地を編成し、染色加工を施した後、水酸化ナトリウム水溶液に前記筒編地を浸漬し、加熱後、乾燥させることで芯糸を減量する。その後、減量前の筒編地から抜き取った混繊糸の所定ウエールの長さ(L1)と減量後の筒編地から抜き取った混繊糸の同じウエールの長さ(L2)に、それぞれ所定の荷重をかけて測定を行い、下記式により糸足差を算出する。
糸足差(%)=(L2-L1)/L1×100
In addition, as a method for measuring the difference in thread length between the core portion and the sheath portion, for example, the following method is exemplified. (Method 1 for measuring thread foot difference)
First, a tubular knitted fabric is knitted using the mixed yarn, and after dyeing, the tubular knitted fabric is immersed in an aqueous sodium hydroxide solution, heated, and dried to produce a core yarn. to lose weight. After that, the predetermined wale length (L1) of the mixed yarn extracted from the tubular knitted fabric before weight reduction and the same wale length (L2) of the mixed yarn extracted from the tubular knitted fabric after weight reduction are set to predetermined values. Measurement is performed by applying a load, and the yarn foot difference is calculated by the following formula.
Thread foot difference (%) = (L2 - L1) / L1 x 100
(糸足差の測定方法2)
布帛から混繊糸を抜き取り、0.1cN(0.1g)×混繊糸の総繊度(dtex)の荷重をとりつけ、5cmの長さにカットし、カットした混繊糸から、芯部用繊維A(単繊維)と鞘部用繊維B(単繊維)とを取り出し、それぞれ、0.1cN(0.1g)×の単繊維繊度(dtex)の荷重をかけて長さを測定し、下記式により糸足差(%)を算出する。
糸足差(%)=(LB-LA)/LA×100
ただし、LAは芯部用繊維Aの糸長(cm)であり、LBは鞘部用繊維Bの糸長(cm)である。
(Method 2 for measuring thread foot difference)
The mixed yarn is pulled out from the fabric, a load of 0.1 cN (0.1 g) × total fineness (dtex) of the mixed yarn is applied, cut to a length of 5 cm, and the cut mixed yarn is used as a core fiber. A (single fiber) and sheath fiber B (single fiber) are taken out, and the length is measured by applying a load of 0.1 cN (0.1 g) × single fiber fineness (dtex), and the length is measured by the following formula. Calculate the yarn foot difference (%).
Thread foot difference (%) = (LB - LA) / LA x 100
However, LA is the yarn length (cm) of the fiber A for the core portion, and LB is the yarn length (cm) of the fiber B for the sheath portion.
また、前記混繊糸だけで布帛を構成してもよいが、前記混繊糸と他の糸条とで布帛を構成してもよい。その際、他の糸条は特に限定されず、非仮撚加工糸、仮撚捲縮加工糸、潜在捲縮糸、紡績糸などのいずれであってもよい。特に、吸水性、速乾性の点で、非仮撚加工糸がより好ましい。 Further, although the cloth may be composed only of the mixed yarn, the cloth may be composed of the mixed yarn and other yarns. In this case, the other yarn is not particularly limited, and may be non-false twisted yarn, false twisted crimped yarn, latently crimped yarn, spun yarn, or the like. In particular, non-false twisted yarn is more preferable in terms of water absorption and quick drying.
速乾性布帛の目付けは、特に限定されるものではないが、ソフト性、乾燥性の観点から、また用途を考えた場合、80~300g/m2が好ましい。速乾性布帛の目付が80g/m2未満であると、シャツ用途として破裂強力などの観点からも好ましくない。また、速乾性の目付が300g/m2を越えると、ウエアー(衣料)として重くなりすぎるおそれがある。 Although the basis weight of the quick-drying fabric is not particularly limited, it is preferably 80 to 300 g/m 2 from the viewpoint of softness and dryness and considering the use. If the quick-drying fabric has a basis weight of less than 80 g/m 2 , it is not preferable from the standpoint of bursting strength for use in shirts. Also, if the quick-drying basis weight exceeds 300 g/m 2 , the wear may become too heavy.
速乾性布帛の組織は特に限定されず、編物、織物いずれでもよい。例えば、平織、綾織、サテンなどの織組織を有する織物や、天竺、ニットミス、スムース、フライス、鹿の子、添え糸編、デンビー、ハーフなどの編組織を有する編物などが例示されるが、これらに限定されるものではない。層数も単層でもよいし、2層以上の多層であってもよい。特に、吸水性、速乾性、ふくらみのあるソフト風合い、抗スナッギング性の点で30~150コース/2.54cmかつ50~80ウエール/2.54cmの範囲にある編物が好ましい。編物の密度が上記範囲未満であると、風合いはソフトになるが抗スナッギング性は低下するおそれがある。また、編物の密度が上記範囲以上であると抗スナッギング性は良くなるが、風合いが硬くなり、速乾性も低下するおそれがある。 The structure of the quick-drying fabric is not particularly limited, and may be either knitted fabric or woven fabric. Examples include woven fabrics having a weave structure such as plain weave, twill weave, and satin; not to be The number of layers may be either a single layer or multiple layers of two or more layers. In particular, knitted fabrics having a range of 30 to 150 courses/2.54 cm and 50 to 80 wales/2.54 cm are preferred in terms of water absorbency, quick drying, bulging soft texture, and anti-snugging properties. If the density of the knitted fabric is less than the above range, the texture will be soft, but the anti-snagging property may be lowered. If the density of the knitted fabric is more than the above range, the anti-snagging property is improved, but the texture may be hard and the quick-drying property may be deteriorated.
次に、本発明の繊維製品は、前記の速乾性布帛を用いてなる、スポーツウエアー、アウターウエアー、インナーウエアー、紳士衣料、婦人衣料、介護用衣料、作業衣、カーシート表皮材、および寝具からなる群より選択されるいずれかの繊維製品である。
