Description
本発明は、肌着、下着等の繊維製品に好適な、ポリプロピレン繊維（以下、ＰＰ繊維ということもある）を用いた、軽くて薄くても保温性に優れた上に吸水・速乾性能を有する編地、及びこれを用いた繊維製品に関する。 The present invention uses polypropylene fibers (hereinafter sometimes referred to as PP fibers) suitable for textile products such as underwear and underwear, and is light and thin and has excellent heat retention and water absorption and quick drying performance. The present invention relates to a knitted fabric and a textile product using the same.
従来、肌着等は各種繊維による一枚の編成地により形成されており、これで充分な温かさが得られないときは、厚手の編成地が用いられている。しかし、厚手の編成地とすることで、保温性は向上するものの重く、温かいための発汗により、汗を含んだ肌側層が肌に接して冷感や不快感を与えることが多く、又、一枚の編成地であることから、外気の侵入による冷えもあって満足すべき効果が得られていない。一方、ポリプロピレン繊維は軽量性、強度、保温性等に優れていることで知られていたが、染色性等の問題があるため、編地原料としてほとんど使用されていなかったが、ポリプロピレン繊維の優れた物性を有効に利用するため、ポリプロピレン糸で片面を形成し、他面をポリプロピレン糸とは異なる材質から成る糸を用いたリバーシブル丸編地が特許文献１に記載されている。又、ダブルフェイス編みにより肌側となる内層がポリプロピレン繊維糸で、３層構造に編成され、これら３層の公定水分率は外層が最も高く、中層、内層の順に小さくなる繊維糸で構成された軽量保温衣類が特許文献２に記載されている。 Conventionally, underwear and the like have been formed from a single knitted fabric made of various fibers, and if this does not provide sufficient warmth, a thick knitted fabric is used. However, by making it a thick knitted fabric, the heat retention is improved, but it is heavy, sweating for warmth often causes the skin side layer containing sweat to touch the skin and give cold feeling and discomfort, Since it is one piece of knitting place, there is a cooling effect due to intrusion of outside air, and a satisfactory effect is not obtained. Polypropylene fiber, on the other hand, was known for its excellent lightness, strength, heat retention, etc., but was rarely used as a knitted fabric material due to problems such as dyeability. Patent Document 1 describes a reversible circular knitted fabric in which one side is formed of polypropylene yarn and the other side is made of a material different from polypropylene yarn in order to effectively use the physical properties. Also, the inner layer on the skin side by double face knitting is knitted into a three-layer structure with polypropylene fiber yarns, and the official moisture content of these three layers is the highest in the outer layer, and is composed of fiber yarns that become smaller in the order of the middle layer and the inner layer. A lightweight heat insulating garment is described in Patent Document 2.
特許文献１に記載のリバーシブル丸編地は、ポリプロピレン糸と羊毛糸との組合せが記載されており、水分保持率の差を利用して汗等が肌面側から外側へ向けて編地内を貫流し外面から蒸散することが記載されているものの、ポリプロピレン糸使いの衣類はドライクリーニングに適さないことから水洗濯をすることとなる。この場合、羊毛糸は水分保持率が高いため衣類全体としての速乾性が不明である。特許文献２に記載の軽量保温衣類は、肌側となる内層がポリプロピレン繊維糸で構成された構成が記載されており、発汗しても肌を常にドライで濡れ戻りがない状態に保持されることが記載されているものの、濡れ戻り試験は重りで数分間押圧するとの記載があり、吸水・速乾性という面からみた場合不明である。 The reversible circular knitted fabric described in Patent Document 1 describes a combination of polypropylene yarn and wool yarn, and sweat or the like flows through the knitted fabric from the skin surface toward the outside using the difference in moisture retention rate. Although it is described that transpiration from the outer surface, clothing using polypropylene yarn is not suitable for dry cleaning, so it is washed with water. In this case, since the wool yarn has a high moisture retention rate, the quick-drying property of the entire clothing is unknown. The lightweight heat-insulating garment described in Patent Document 2 describes a configuration in which the inner layer on the skin side is composed of polypropylene fiber yarns, and the skin is always kept dry and free from rewetting even when sweating. However, there is a description that the wet-back test presses for several minutes with a weight, and it is unclear when viewed from the viewpoint of water absorption and quick drying.
本発明は、ＰＰ繊維が持つ軽量、保温等の機能を活かし、軽くて薄くても保温性を有した上に、特に重りで押圧等の処理をしないでも吸水・速乾性能に優れた編地、及びこれを用いた繊維製品を提供することを目的とする。 The present invention makes use of the functions of PP fibers such as light weight and heat retention, and has a heat retention property even if it is light and thin, and is excellent in water absorption and quick drying performance even without being treated by pressing with a weight in particular. And a textile product using the same.
本発明は、上記の目的を達成するため、肌側となる内層と、外層とこれらを繋ぐ接結糸条で構成され、前記内層が繊度０．３〜３．０ｄｔｅｘのポリプロピレン繊維を含む糸条で構成され、前記外層及び接結糸条が異型断面の疎水性合成繊維糸条で構成された編地、及びこれを用いた繊維製品を提供するものである。 In order to achieve the above-mentioned object, the present invention is composed of an inner layer on the skin side, an outer layer and a binding yarn connecting these layers, and the inner layer includes a polypropylene fiber having a fineness of 0.3 to 3.0 dtex. And the outer layer and the binding yarn are formed of a hydrophobic synthetic fiber yarn having an irregular cross section, and a fiber product using the same.
本発明の編地は、上記構成を採用することにより、染色性にも優れ実用的な繊維製品を提供するとともに、軽くて薄くても保温性に優れ、吸水・速乾性能を有するという効果を奏するものである。 The knitted fabric of the present invention adopts the above-described configuration to provide a practical textile product with excellent dyeability and excellent heat retention even when light and thin, and has the effect of having water absorption and quick drying performance. It is what you play.
以下、本発明の実施形態について説明する。
本発明の編地は、肌側となる内層と、外層とこれを繋ぐ接結糸条で構成されている。内層を構成する繊維は繊度０．３〜３．０ｄｔｅｘのＰＰ繊維を含む糸条で構成されている。ＰＰ繊維は熱伝導性がセルロース繊維等に比して低く、これにより外界の低温から身体を守り、体温の放散を抑制することができる。又、ＰＰ繊維の比重は０．９１ｇ／ｃｍ3と一般的な繊維の中では最も軽い繊維であるため、この繊維を用いた編地は軽量とすることもできる。
Hereinafter, embodiments of the present invention will be described.
The knitted fabric of the present invention is composed of an inner layer on the skin side, an outer layer, and a binding yarn that connects the outer layer. The fibers constituting the inner layer are composed of yarns containing PP fibers having a fineness of 0.3 to 3.0 dtex. PP fibers have lower thermal conductivity than cellulose fibers and the like, thereby protecting the body from low temperatures in the outside world and suppressing the dissipation of body temperature. Moreover, since the specific gravity of PP fiber is 0.91 g / cm 3 and is the lightest fiber among general fibers, the knitted fabric using this fiber can be light.
本発明で用いられるＰＰ繊維は、単一繊維、又は複合繊維いずれであってもよく、染色性等の問題を解決するためには原着繊維、ポリプロピレンナイロンアロイ、ポリプロピレンポリエステルアロイ等可染性ポリマーを含むＰＰ繊維を用いてもよい。 The PP fiber used in the present invention may be either a single fiber or a composite fiber, and in order to solve problems such as dyeability, a dyeable polymer such as an original fiber, a polypropylene nylon alloy, a polypropylene polyester alloy, etc. PP fibers containing may be used.
ＰＰ繊維が複合繊維の場合、芯成分がポリプロピレン、鞘成分がポリエステルである芯鞘型複合繊維が好ましい。又、芯成分のポリプロピレンのメルトフローレート（ＪＩＳ Ｋ ７２１０に準じて、２３０℃ ２１．２Ｎで測定）が２８ｇ／１０ｍｉｎを超えて６０ｇ／ｍｉｎ未満であることが好ましく、メルトフローレートが４０ｇ／１０ｍｉｎを超えて５５ｇ／１０ｍｉｎ以下であることがより好ましい。これにより、実生産が可能な程度に糸切れはなく安定して紡糸でき、染色性も良好な芯鞘型複合繊維とすることができる。又、芯成分と鞘成分の複合割合は質量比で芯成分：鞘成分＝２０〜８０：８０〜２０の範囲であることが好ましく、速乾性や保温性の観点からは、芯成分：鞘成分＝４０〜７０：６０〜３０の範囲がより好ましい。又、染色性の観点からは、芯成分：鞘成分＝３０〜６０：７０〜４０の範囲がより好ましい。ポリプロピレンの比重は０．９０〜０．９１，ポリエステルの比重は１．３〜１．４であり（ＡＳＴＭ Ｄ７９２による測定）、前記範囲であれば複合繊維の比重を軽くでき、更に染色可能なポリエステルとすることができる。 When the PP fiber is a composite fiber, a core-sheath type composite fiber in which the core component is polypropylene and the sheath component is polyester is preferable. The melt flow rate (measured at 230 ° C. and 21.2 N in accordance with JIS K 7210) of the core component polypropylene is preferably more than 28 g / 10 min and less than 60 g / min, and the melt flow rate is 40 g / 10 min. Is more preferably 55 g / 10 min or less. Thereby, it is possible to obtain a core-sheath type composite fiber that can be stably spun without thread breakage to such an extent that actual production is possible, and has good dyeability. The composite ratio of the core component and the sheath component is preferably in the range of core component: sheath component = 20-80: 80-20 by mass ratio. From the viewpoint of quick drying and heat retention, the core component: sheath component = 40-70: The range of 60-30 is more preferable. Further, from the viewpoint of dyeability, the range of core component: sheath component = 30-60: 70-40 is more preferable. Polypropylene has a specific gravity of 0.90 to 0.91, and polyester has a specific gravity of 1.3 to 1.4 (measured according to ASTM D792). It can be.
ＰＰ繊維の繊度は、単一、複合に関わらず０．３〜３.０ｄｔｅｘの範囲のものが好ましく、０．５〜１.５ｄｔｅｘの範囲のものがより好ましい。この範囲であれば触感が柔かく、同じ番手の紡績糸で比較した場合、繊維の構成本数が多くなることから、安定した強力等の繊維物性が得られる。又、毛細管現象による吸水・速乾性能の向上もみられ、それを用いた繊維製品等に好適である。 The fineness of the PP fiber is preferably in the range of 0.3 to 3.0 dtex, more preferably in the range of 0.5 to 1.5 dtex, regardless of single or composite. Within this range, the tactile feel is soft, and when compared with spun yarns of the same count, the number of fibers increases, so that stable fiber properties such as strength can be obtained. In addition, improvement in water absorption and quick drying performance due to capillary action is also seen, which is suitable for textile products and the like using the same.
内層を構成するＰＰ繊維を含む糸条は、紡績糸、マルチフィラメント、モノフィラメント等特にこだわらないが、紡績糸であることが好ましい。当該紡績糸は、リング法、オープンエンド法、結束法、交互撚糸法、ラッピング法、渦流法又は無撚法等いずれの方法で製造してもよいが、渦流法によることが好ましい。この方法はリング法に比べて、紡績糸の製造工程において、繊維がしごき、ないしは摩擦を受けることが少なく、損傷の少ない糸とすることができるからである。その結果、染色物の欠点の少ない編地とすることができる。具体的には、ポリプロピレンの露出による白化現象が抑えられる。渦流法による紡績機としては、村田機械株式会社製「ＭＶＳ」がある。紡績糸の好ましい番手は英式番手で５〜１００Ｓの範囲である。より好ましくは、英式綿番手で１０〜６０Ｓの範囲である。この範囲であれば好適な編地が得られる。なお、得られた紡績糸は単糸使いでも複数本撚りあわせて使用してもよい。 The yarn containing PP fibers constituting the inner layer is not particularly limited, such as spun yarn, multifilament, monofilament, but is preferably spun yarn. The spun yarn may be produced by any method such as a ring method, an open end method, a bundling method, an alternating twist method, a wrapping method, a vortex method, or a non-twist method, but the vortex method is preferred. This is because, in comparison with the ring method, the fiber is less susceptible to squeezing or friction in the production process of the spun yarn, and the yarn is less damaged. As a result, a knitted fabric with few defects of the dyed product can be obtained. Specifically, the whitening phenomenon due to the exposure of polypropylene is suppressed. As a spinning machine by the eddy current method, there is “MVS” manufactured by Murata Machinery Co., Ltd. The preferred count of the spun yarn is an English count and ranges from 5 to 100S. More preferably, it is the range of 10-60S by an English cotton count. If it is this range, a suitable knitted fabric will be obtained. The obtained spun yarn may be used as a single yarn or a plurality of twisted yarns.
紡績糸を構成する繊維の構成本数は、９０本以上であることが好ましく、１００本以上であることがより好ましい。好ましい繊維の構成本数の上限は５００本である。紡績糸を構成する繊維の構成本数が９０本以上であると、精紡工程等で糸切れし難い。 The number of fibers constituting the spun yarn is preferably 90 or more, and more preferably 100 or more. The upper limit of the preferred number of fibers is 500. If the number of fibers constituting the spun yarn is 90 or more, it is difficult to break the yarn in the spinning process or the like.
紡績糸を使用することにより、繊維内の空隙が細かくなり繊維内の不動空気層が増加し、保温性が高くなるという効果を奏することができるとともに、細かい空隙が増えることにより、吸水性も増すという効果も奏する。当該紡績糸は、ＰＰ繊維が単一繊維の場合は、１０質量％以上含んだものであることが好ましい。より好ましくは、２０質量％以上含んだものである。更に好ましくは３０質量％含んだものである。ＰＰ繊維の含有量が１０質量％未満であれば、保温性・軽量性が悪くなるからである。ＰＰ繊維が複合繊維の場合にも、当該複合繊維を１０質量％以上含んだものであることが好ましく、２０質量％以上含んだものであることがより好ましい。複合繊維１００質量％であっても差し支えない。 By using the spun yarn, the voids in the fiber become finer, the immobile air layer in the fiber increases, and the heat retaining property can be improved, and the water absorption increases by increasing the fine voids. There is also an effect. The spun yarn preferably contains 10 mass% or more when the PP fiber is a single fiber. More preferably, it contains 20% by mass or more. More preferably, it contains 30% by mass. This is because if the PP fiber content is less than 10% by mass, the heat retaining property and lightness are deteriorated. Even when the PP fiber is a composite fiber, the composite fiber preferably contains 10% by mass or more, and more preferably contains 20% by mass or more. The composite fiber may be 100% by mass.
内層の糸条はＰＰ繊維と他の繊維を組合せてもよい。組合せの方法としては、混紡、合糸、混繊、引揃え、交編等いずれでもよい。内層の糸条を構成するＰＰ繊維以外の繊維として、例えば、アクリル系繊維、ナイロン、ポリエステル系繊維、ポリオレフィン繊維、ナイロン繊維、レーヨン繊維、キュプラ繊維、アセテート繊維、エチレンビニルアルコール繊維、ウレタン繊維、コットン繊維、麻繊維、絹繊維、ウール繊維、又はカシミア繊維が一例として挙げられ、前記繊維を複数組合せてもよい。なかでも組合せる繊維としては、ポリエステル系繊維、アクリル系繊維、ウレタン繊維又はウール繊維であることが好ましい。 The inner layer yarn may be a combination of PP fibers and other fibers. As a combination method, any of mixed spinning, synthetic yarn, mixed fiber, drawing, knit, and the like may be used. Examples of fibers other than PP fibers constituting the inner layer yarn include acrylic fibers, nylon, polyester fibers, polyolefin fibers, nylon fibers, rayon fibers, cupra fibers, acetate fibers, ethylene vinyl alcohol fibers, urethane fibers, and cotton. Examples of the fibers include hemp fibers, silk fibers, wool fibers, and cashmere fibers, and a plurality of the fibers may be combined. Among them, the fibers to be combined are preferably polyester fibers, acrylic fibers, urethane fibers, or wool fibers.
ＰＰ繊維とアクリル系繊維との組合せが好ましい。アクリル系繊維は嵩高で保温性があるからである。又、アクリル系繊維は、他の繊維と混紡して鮮やかな色彩を出せるという特徴を有することから、染色性の問題もクリアできる。アクリル系繊維の混紡割合は１０〜９０質量％であることが好ましい。ポリプロピレンの公定水分率は０．０％、アクリルは２．０％であることから、ＰＰ繊維とアクリル系繊維を混紡することにより、みかけの公定水分率が０．２〜１．８％となり、吸水・速乾性能にも寄与すると考えられる。ここで、みかけの公定水分率は、当該繊維の公定水分率に混紡割合を乗じて簡易的に求めたものを使用している。なお、複合繊維の場合もその芯部、鞘部の配合割合に応じて同様に求めている。アクリル系繊維の繊度は、０．３〜３．０ｄｔｅｘの範囲のものが好ましく、０．５〜１．５ｄｔｅｘの範囲のものがより好ましい。この範囲であれば繊維製品等に好適である。 A combination of PP fibers and acrylic fibers is preferred. This is because acrylic fibers are bulky and have heat retention. In addition, since acrylic fibers have a characteristic that they can be blended with other fibers to produce vivid colors, the problem of dyeability can be cleared. The blend ratio of acrylic fibers is preferably 10 to 90% by mass. Since the official moisture content of polypropylene is 0.0% and acrylic is 2.0%, by blending PP fiber and acrylic fiber, the apparent official moisture content becomes 0.2-1.8%, It is thought to contribute to water absorption and quick drying performance. Here, the apparent official moisture content is obtained simply by multiplying the official moisture content of the fiber by the blend ratio. In the case of a composite fiber, it is similarly determined according to the blending ratio of the core part and the sheath part. The fineness of the acrylic fiber is preferably in the range of 0.3 to 3.0 dtex, and more preferably in the range of 0.5 to 1.5 dtex. If it is this range, it is suitable for textiles etc.
ＰＰ繊維とポリエステル繊維との組合せも好ましい。ポリエステル系繊維は、公定水分率が０．４％と低く、強い疎水性であることから、ポリエステル繊維自体は保水せず、吸水処理剤等を使用することにより汗等を拡散するので、速乾性という面から好ましいからである。ポリエステル繊維の繊度は、０．３〜３．０ｄｔｅｘの範囲のものが好ましく、０．５〜１．５ｄｔｅｘの範囲のものがより好ましい。この範囲であれば繊維製品等に好適である。 A combination of PP fibers and polyester fibers is also preferred. Polyester fiber has a low official moisture content of 0.4% and strong hydrophobicity, so the polyester fiber itself does not retain water and diffuses sweat, etc. by using a water-absorbing agent, etc. This is because of this. The fineness of the polyester fiber is preferably in the range of 0.3 to 3.0 dtex, more preferably in the range of 0.5 to 1.5 dtex. If it is this range, it is suitable for textiles etc.
なお、上記の組合せにさらにウレタン繊維を組合せてもよい。ウレタン繊維は伸縮性に優れており、かつ緩やかに収縮するので、柔らかい風合いを活かしながら、ストレッチ性を付与した編地が得られる。 Note that urethane fibers may be further combined with the above combinations. Urethane fiber is excellent in stretchability and contracts slowly, so that a knitted fabric with stretchability can be obtained while utilizing a soft texture.
次にＰＰ繊維の製造方法について説明する。
単一のＰＰ繊維を製造するには、高温下で押出機にてポリプロピレン樹脂を溶融させ、ノズルからＰＰ繊維を紡糸する。このポリプロピレン樹脂には酸化劣化を抑制するフェノール系の安定剤を添加しておくことが好ましい。但し、ＰＰ繊維は表面積が大きく、様々なガスと接触する機会が多い。特に、ＮＯｘやＳＯｘガスとの接触やアルカリにより変色するフェノール系の安定剤は避けておくようにする。又、リン系やラクトン系の安定剤を併用することでＰＰ繊維製造時の酸化劣化を抑制する効果は向上する。次に、ＰＰ繊維の使用状況において、高温下での長時間の使用や紫外線が当たる場所での使用など過酷な条件を想定する必要があり、この場合はフェノール系をベースにＨＡＬＳ系の安定剤を併用することが好ましいが、洗濯耐久性等を考慮すると、出来るだけ高分子量のものが好ましい。
Next, the manufacturing method of PP fiber is demonstrated.
In order to produce a single PP fiber, a polypropylene resin is melted in an extruder at a high temperature, and the PP fiber is spun from a nozzle. It is preferable to add a phenol-based stabilizer that suppresses oxidative degradation to the polypropylene resin. However, PP fibers have a large surface area and often come into contact with various gases. In particular, a phenol-based stabilizer that changes color due to contact with NOx or SOx gas or alkali is avoided. Further, the combined use of a phosphorus-based or lactone-based stabilizer improves the effect of suppressing oxidative degradation during PP fiber production. Next, it is necessary to assume harsh conditions such as long-term use at high temperatures and use in places exposed to ultraviolet rays in the use of PP fiber. In this case, a HALS-based stabilizer based on phenol Is preferably used in combination, but in view of washing durability and the like, those having a high molecular weight are preferable.
芯成分がポリプロピレン、鞘成分がポリエステルである芯鞘型複合繊維を製造するための方法は、芯成分のポリプロピレンはメルトフローレートが２８ｇ／１０ｍｉｎを超えて６０ｇ／１０ｍｉｎ未満の範囲とし、芯成分と鞘成分を複合紡糸口金から芯鞘状態で溶融紡糸して未延伸糸とし、得られた未延伸糸を延伸し、定長又は緊張熱処理セットするのが好ましい。前記において、延伸後の定長又は緊張熱処理セットは、寸法安定化のために行う。この定長又は緊張熱処理セットにより、後の工程で収縮や弛緩が起こることを防止できる。延伸後の定長又は緊張熱処理セットは、８５〜１００℃の熱水中で行うのが好ましい。時間は１５秒〜１８０秒間程度が好ましい。この方法において、延伸は５０〜７０℃程度の比較的低温の温水浴中で湿式延伸するのが好ましい。穏やかな延伸条件により、芯成分と鞘成分の剥離を起こさないようにするためである。又、比較的低温で延伸することにより、ポリエステル成分の加水分解を防止し、繊維同士の融着ないしは膠着も防止できる。延伸倍率は１．３〜３．５倍程度の比較的穏やかな延伸条件が好ましい。より好ましくは１．８〜２．７倍である。これも芯成分と鞘成分の剥離を起こさないようにするためである。好ましい製造工程は、延伸し、定長又は緊張熱処理セットし、クリンパーで捲縮を付与し、乾燥する工程である。乾燥は１０５〜１１５℃の温度で、１５分間程度乾燥機で行う。この複合繊維を紡績糸や不織布にするには、トウの状態で乾燥工程まで行い、その後所定の繊維長にカットする。フィラメントにする場合は、延伸し、定長又は緊張熱処理セットし巻き取る。 The method for producing a core-sheath type composite fiber in which the core component is polypropylene and the sheath component is polyester is that the core component polypropylene has a melt flow rate in the range of more than 28 g / 10 min and less than 60 g / 10 min. It is preferable that the sheath component is melt-spun from the composite spinneret in a core-sheath state to obtain an unstretched yarn, and the obtained unstretched yarn is stretched and set to constant length or tension heat treatment. In the above, the constant length or tension heat treatment set after stretching is performed for dimensional stabilization. By this constant length or tension heat treatment set, it is possible to prevent shrinkage or relaxation from occurring in a later process. It is preferable to perform the constant length or tension heat treatment set after stretching in hot water at 85 to 100 ° C. The time is preferably about 15 seconds to 180 seconds. In this method, the stretching is preferably performed by wet stretching in a relatively low temperature hot water bath of about 50 to 70 ° C. This is to prevent peeling of the core component and the sheath component under mild stretching conditions. Further, by stretching at a relatively low temperature, hydrolysis of the polyester component can be prevented, and fusion or sticking of fibers can also be prevented. The stretching ratio is preferably a relatively mild stretching condition of about 1.3 to 3.5 times. More preferably, it is 1.8 to 2.7 times. This is also to prevent peeling of the core component and the sheath component. A preferable production process is a process of stretching, setting a constant length or tension heat treatment, applying crimp with a crimper, and drying. Drying is performed at a temperature of 105 to 115 ° C. with a dryer for about 15 minutes. In order to make this composite fiber into a spun yarn or a nonwoven fabric, it is carried out in a tow state until a drying step, and then cut into a predetermined fiber length. When it is made into a filament, it is stretched, set to a constant length or tension heat treatment, and wound.
外層、及び接結糸条を構成する繊維は異型断面の疎水性合成繊維である。ここで、疎水性とは、公定水分率４．０％以下のものをいう。この疎水性合成繊維糸条の形態は、スパン糸条、フィラメント糸条等特にこだわらないが、マルチフィラメント糸条であることが好ましい。マルチフィラメントの繊度は５０〜１００デニールであることが好ましく、当該マルチフィラメントを構成する繊維本数は３０〜３００本であることが好ましい。この範囲のマルチフィラメントで構成した糸条を使用することにより、編地の表面性が良好となるうえ、汗が拡散されやすく、かつ、繊維間に汗が保持されにくくなり、汗が移行されやすい状態を作る。 The fibers constituting the outer layer and the binding yarn are hydrophobic synthetic fibers having an irregular cross section. Here, the hydrophobic property means that the official moisture content is 4.0% or less. The form of the hydrophobic synthetic fiber yarn is not particularly limited, such as a spun yarn or a filament yarn, but is preferably a multifilament yarn. The fineness of the multifilament is preferably 50 to 100 denier, and the number of fibers constituting the multifilament is preferably 30 to 300. By using yarns composed of multifilaments in this range, the surface property of the knitted fabric is improved, sweat is easily diffused, and sweat is not easily held between the fibers, and sweat is easily transferred. Make a state.
外層、及び接結糸条を構成する疎水性合成繊維は異型断面であることが好ましい。ここで、異型断面とは、Ｕ型、Ｗ型、星型、扁平型等いずれであってもよく特にこだわらない。外層、及び接結糸条を構成する疎水性合成繊維を異型断面とすることにより、繊維の表面積増加による毛細管現象がより顕著になり、吸水・速乾性能が向上すると考えられる。 It is preferable that the hydrophobic synthetic fiber constituting the outer layer and the binding yarn has an atypical cross section. Here, the atypical cross section may be any of a U shape, a W shape, a star shape, a flat shape, etc., and is not particularly limited. It is thought that by forming the hydrophobic synthetic fiber constituting the outer layer and the binding yarn into an atypical cross section, the capillary phenomenon due to the increase in the surface area of the fiber becomes more prominent and the water absorption and quick drying performance is improved.
外層、及び接結糸条を構成する異型断面の疎水性合成繊維は異なっていてもよいが、同じ繊維を使用することが好ましい。疎水性合成繊維糸条を構成する繊維としては、例えば、ポリエステル系繊維、アクリル系繊維、ポリプロピレン繊維、ポリオレフィン繊維、ウール繊維等が挙げられ、これらの内の一種、又は数種を組合せてもよい。又、ストレッチ性をより発揮させるため、ポリウレタン繊維を入れてもよい。この中でもポリエステル系繊維を用いることが汎用性の点から好ましい。低温にて染色できるタイプのポリエステル系繊維が染色性の点からみて好ましい。低温にて染色できるタイプのポリエステル系繊維としては、例えば、カチオンダイアブルポリエステル繊維が挙げられる。疎水性合成繊維の繊度は、０．３〜３．０ｄｔｅｘの範囲のものが好ましく、０．５〜２．０ｄｔｅｘの範囲のものがより好ましい。この範囲であれば繊維製品等に好適である。 The outer layer and the hydrophobic synthetic fiber having an irregular cross section constituting the binding yarn may be different, but it is preferable to use the same fiber. Examples of the fibers constituting the hydrophobic synthetic fiber yarn include polyester fibers, acrylic fibers, polypropylene fibers, polyolefin fibers, and wool fibers, and one or a combination of these may be used. . Moreover, in order to exhibit stretch property more, you may put a polyurethane fiber. Of these, the use of polyester fibers is preferred from the viewpoint of versatility. From the viewpoint of dyeability, polyester fibers of a type that can be dyed at low temperatures are preferred. Examples of the type of polyester fiber that can be dyed at a low temperature include cationic diable polyester fibers. The fineness of the hydrophobic synthetic fiber is preferably in the range of 0.3 to 3.0 dtex, more preferably in the range of 0.5 to 2.0 dtex. If it is this range, it is suitable for textiles etc.
なお、接結糸条及び外層を構成する疎水性合成繊維糸条とも原着繊維や可染性ポリマーを含む繊維を用いて本発明の編地とすることもできる。 In addition, both the binding yarn and the hydrophobic synthetic fiber yarn constituting the outer layer can also be used as the knitted fabric of the present invention by using fibers containing an original fiber and a dyeable polymer.
内層を構成するＰＰ繊維を含む糸条、接結糸条及び外層を構成する異型断面の疎水性合成繊維糸条との組合せとしては、春夏又は通年向けの繊維製品用として、内層はＰＰ繊維とポリエステル系繊維、接結糸条及び外層がポリエステル系繊維の組合せ、秋冬向けの繊維製品用として、内層がＰＰ繊維とアクリル繊維、又はウール繊維、接結糸条及び外層がアクリル繊維、又はウール繊維の組合せが好ましい。両方の組合せにおいてさらにウレタン繊維を組合せてもよい。 As a combination of the yarn containing PP fiber constituting the inner layer, the binding yarn, and the hydrophobic synthetic fiber yarn having an irregular cross section constituting the outer layer, the inner layer is made of PP fiber for use in textile products for spring / summer or all year. And polyester fiber, binding yarn and outer layer are a combination of polyester fiber, and for textile products for fall and winter, inner layer is PP fiber and acrylic fiber, or wool fiber, binding yarn and outer layer is acrylic fiber, or wool A combination of fibers is preferred. Urethane fibers may be further combined in both combinations.
本発明の編地は、ＰＰ繊維を５質量％以上含むことが好ましく、１０質量％以上含むことがより好ましい。ＰＰ繊維を３０質量％以上含むことがさらに好ましい。ＰＰ繊維が５質量％未満であれば、保温性が悪くなるからである。 The knitted fabric of the present invention preferably contains 5% by mass or more of PP fiber, more preferably 10% by mass or more. More preferably, 30% by mass or more of PP fiber is contained. This is because if the PP fiber is less than 5% by mass, the heat retaining property is deteriorated.
本発明の編地は、内層が０．３〜３．０ｄｔｅｘのポリプロピレン繊維を含む糸条で構成され、外層及び接結糸条が異型断面の疎水性合成繊維糸条で構成された組織であれば特に限定されないが、編地内外層を異なる組織で編成したり、編地内層を粗、外層を密にした粗密構造にしたりすることが好ましい。又、本発明の編地は、肌側となる内層と外層、これらを繋ぐ接結糸条で構成されているが、当該編地を横方向からみた断面形状において必ずしも明確に三層構造として確認できる必要はないが、ダブルフェイス編、又はダンボール編とすることが好ましい。これらの編み方とすることにより、空気層を多く含み保温性を良好とすることができ、好ましい。なお、ここで、ダブルフェイス編は、内層と外層の編組織が異なるものを、ダンボール編は、内層と外層の編組織が同じで、空間部に空気層を有しているものをいう。 The knitted fabric of the present invention may have a structure in which the inner layer is composed of yarns containing polypropylene fibers of 0.3 to 3.0 dtex, and the outer layer and the binding yarns are composed of hydrophobic synthetic fiber yarns having a modified cross section. Although not particularly limited, it is preferable that the inner and outer layers of the knitted fabric are knitted with different structures, or that the inner layer of the knitted fabric is rough and the outer layer is densely formed. In addition, the knitted fabric of the present invention is composed of an inner layer and an outer layer on the skin side, and a binding yarn connecting these, but the cross-sectional shape of the knitted fabric viewed from the lateral direction is always clearly confirmed as a three-layer structure. Although it is not necessary, it is preferable to use a double face knitting or a cardboard knitting. These knitting methods are preferable because they can contain many air layers and have good heat retention. Here, the double face knitting means that the inner layer and the outer layer have different knitting structures, and the corrugated cardboard knitting means that the inner layer and the outer layer have the same knitting structure and has an air layer in the space.
本発明の編地は、良好な吸水拡散性能を有し、従って良好な吸水・速乾性能をも有する。ここで、吸水拡散性能は、０．２ｍｌの純水を滴下した時の吸水性を吸水時間及び吸水拡散面積にて評価している。即ち、本発明の編地は、０．２ｍｌの純水を滴下した時に、吸水時間が５秒以下で、１分後の吸水拡散面積が１０ｃｍ2以上であるような吸水性を有し得る。吸水時間及び吸水拡散面積の測定方法は後述する。 The knitted fabric of the present invention has good water absorption / diffusion performance, and therefore also has good water absorption / quick drying performance. Here, with respect to the water absorption and diffusion performance, the water absorption when 0.2 ml of pure water is dropped is evaluated by the water absorption time and the water absorption diffusion area. That is, the knitted fabric of the present invention can have water absorption such that when 0.2 ml of pure water is dropped, the water absorption time is 5 seconds or less and the water absorption diffusion area after 1 minute is 10 cm 2 or more. The measuring method of water absorption time and a water absorption diffusion area is mentioned later.
ＰＰ繊維を含む糸条と異型断面の疎水性合成繊維糸条ともに吸水性能を向上させたりしてもよい。ＰＰ繊維を含む糸条と異型断面の疎水性合成繊維糸条の吸水性能を向上させるためには、例えば、吸水処理剤を使用して行うことができる。この吸水処理剤は、編地編成前の繊維の段階で使用してもよいし、編地を染色加工する際や仕上加工時に使用してもよく、編地内部にまで浸透できれば、塗布方法も特にこだわらない。吸水処理剤としては、例えば、適量の高松油脂株式会社製ＳＲ−１０００を使用することができる。ここで、吸水性能が向上しているとは、当該繊維糸条を用いた編地上に水滴を垂らし、丸くなった水滴と編地が接触する角度が３０度よりも小さくなる場合を指している。ちなみにフライパンなどの表面処理に使われている撥水素材の接触角度は約１１０度といわれている。なお、接触角度の測定方法はθ／２法による。即ち、液滴の左右端点と頂点を結ぶ直線の固体表面に対する角度から求める方法である。この方法は、液滴が球の一部であることを前提にしているため、重力の影響を無視できる液滴量で測定し、分度器にて直読することにより測定できる。 Both the yarn containing PP fibers and the hydrophobic synthetic fiber yarn having an irregular cross section may improve water absorption performance. In order to improve the water absorption performance of the yarn containing PP fibers and the hydrophobic synthetic fiber yarn having an irregular cross section, for example, a water absorption treatment agent can be used. This water-absorbing treatment agent may be used at the fiber stage before knitting, or may be used when dyeing or finishing the knitted fabric. I'm not particular about it. As the water absorption treatment agent, for example, an appropriate amount of SR-1000 manufactured by Takamatsu Yushi Co., Ltd. can be used. Here, the improvement in water absorption performance refers to a case where a water droplet is dropped on the knitted fabric using the fiber yarn, and the angle at which the rounded water droplet contacts the knitted fabric is smaller than 30 degrees. . By the way, the contact angle of water repellent material used for surface treatment such as frying pan is said to be about 110 degrees. The contact angle is measured by the θ / 2 method. That is, it is a method of obtaining from the angle of the straight line connecting the left and right end points and the vertex of the droplet to the solid surface. Since this method is based on the premise that the droplet is a part of a sphere, it can be measured by measuring the amount of droplet with negligible influence of gravity and directly reading with a protractor.
編地を染色加工、又は仕上加工する際には吸水処理剤の他に抗菌剤や帯電防止剤等を併用して使用することもできる。 When dyeing or finishing the knitted fabric, an antibacterial agent or an antistatic agent can be used in combination with the water absorption treatment agent.
本発明の編地には染色加工（精練、染色、柔軟仕上等を含む）を施している。又、特に断りの無い限り、各測定データは、染色加工後の編地についての測定値を示している。 The knitted fabric of the present invention is subjected to dyeing (including scouring, dyeing, soft finishing, etc.). Unless otherwise specified, each measurement data indicates a measurement value for the knitted fabric after dyeing.
本発明の編地は、通常の編地と同様、繊維製品の素材として用いられて、繊維製品を与える。具体的には、下着、肌着、スポーツ衣料、防寒衣料等様々な繊維製品が提供される。ＰＰ繊維は熱伝導性が小さいため、内層に繊度が０．３〜３．０ｄｔｅｘのＰＰ繊維を含む糸条で構成することにより、この編地を用いた繊維製品は着用者に柔かさと温かさを与え、冷え感（特に、汗冷え）が小さく、皮膚温度の低下を抑える。汗は肌面側のＰＰ繊維を含む糸条から異型断面を有する疎水性合成繊維糸条で構成される接結糸条及び外層に向けて編地内を通り、外面へ放散することとなるため、乾燥しやすく着用者に快適感を与えることも可能となる。 The knitted fabric of the present invention is used as a raw material for a textile product in the same manner as a normal knitted fabric to give a textile product. Specifically, various textile products such as underwear, underwear, sports clothing, and cold clothing are provided. Since PP fiber has low thermal conductivity, the fiber product using this knitted fabric is soft and warm to the wearer by being composed of yarn containing PP fiber having a fineness of 0.3 to 3.0 dtex in the inner layer. Gives a feeling of coldness (especially sweatiness) and suppresses a decrease in skin temperature. Since sweat passes through the knitted fabric toward the binding yarn and the outer layer composed of the hydrophobic synthetic fiber yarn having an atypical cross section from the yarn containing PP fibers on the skin surface side, and is diffused to the outer surface. It is easy to dry, and it is also possible to give comfort to the wearer.
