Description

本発明は、コットン等のセルロース系繊維を主要繊維糸とする吸湿発熱性生地及びこれを用いた吸湿発熱性衣料に関する。 TECHNICAL FIELD The present invention relates to a hygroscopic heat-generating fabric having cellulosic fibers such as cotton as the main yarn, and a hygroscopic heat-generating clothing using the same.

吸湿発熱性は、乾燥した繊維が湿気（水分）を吸収する際に発熱する性質であり、例えば昼間天日に当てた布団を室内に取り込んで、数時間経過し室温と同じ温度になっていても、人体の皮膚を当てると暖かく感ずる現象として知られている。 Hygroscopic heat generation is the property that dry fibers generate heat when they absorb moisture (moisture). It is also known as a phenomenon of feeling warm when the human skin is applied to it.

従来、吸湿発熱性繊維の製造方法として、下記特許文献１には、アクリル系繊維のヒドラジン架橋処理、加水分解処理及びカルボキシル基の塩型への転換からなる高吸放湿性繊維が提案されている。しかし、これらの提案はアクリル系繊維そのものの改質であり、他の繊維に応用することは困難であった。また、芯成分に獣毛繊維を使用し、鞘成分にセルロース繊維などを配置した複合紡績糸を本出願人は提案している（下記特許文献２）。 Conventionally, as a method for producing moisture-absorbing heat-generating fibers, the following patent document 1 proposes highly moisture-absorbing and desorbing fibers comprising acrylic fibers subjected to hydrazine cross-linking treatment, hydrolysis treatment, and conversion of carboxyl groups to salt forms. . However, these proposals are modifications of acrylic fibers themselves, and it is difficult to apply them to other fibers. In addition, the present applicant has proposed a composite spun yarn in which animal hair fibers are used as the core component and cellulose fibers or the like are arranged as the sheath component (Patent Document 2 below).

本発明は、吸湿発熱加工したセルロース系繊維（ａ１）と吸湿発熱加工していないセルロース系繊維（ａ２）を含む混紡紡績糸（Ａ）と、吸湿発熱加工していないセルロース系繊維で構成される紡績糸（Ｂ）を含む吸湿発熱性生地である。生地を１００質量％としたとき、吸湿発熱加工したセルロース系繊維（ａ１）は５～４０質量％である。木綿（コットン）やレーヨンなどのセルロース系繊維には吸湿発熱性があるが（本宮達也ら著「繊維の百科事典」830頁左欄、2002年3月25日、丸善）、これにより適度な吸湿発熱性を付与し、かつ洗濯耐久性のある吸湿発熱衣料を実現できる。さらに、吸湿発熱加工したセルロース系繊維（ａ１）と吸湿発熱加工していないセルロース系繊維（ａ２）を含む混紡紡績糸（Ａ）と、吸湿発熱加工していないセルロース系繊維で構成される紡績糸（Ｂ）と、弾性糸（Ｃ）を含む吸湿発熱性生地であり、生地を１００質量％としたとき、吸湿発熱加工したセルロース系繊維（ａ１）は５～４０質量％であり、セルロース系繊維合計量（Ａ＋Ｂ）は８５～９７質量％であり、弾性糸（Ｃ）は３～１５質量％である。これにより適度な吸湿発熱性を付与し、かつ洗濯を繰り返しても型崩れしにくい吸湿発熱性衣料を実現できる。 The present invention comprises a blended spun yarn (A) containing cellulose fibers (a1) subjected to moisture absorption and heat generation processing and cellulose fibers (a2) not subjected to moisture absorption and heat generation processing, and cellulose fibers not subjected to moisture absorption and heat generation processing. It is a hygroscopic heat-generating fabric containing a spun yarn (B). When the fabric is 100% by mass, the cellulose fiber (a1) subjected to moisture absorption and heat generation is 5 to 40% by mass. Cellulose fibers such as cotton and rayon have hygroscopic and heat-generating properties (Tatsuya Motomiya et al., Encyclopedia of Textiles, page 830, left column, March 25, 2002, Maruzen), which allows moderate moisture absorption. Moisture-absorbing heat-generating clothing that imparts heat-generating properties and is durable to washing can be realized. Further, a blended spun yarn (A) containing cellulose fibers (a1) subjected to moisture absorption and heat generation and cellulose fibers (a2) not subjected to moisture absorption and heat generation, and spun yarn composed of cellulose fibers not subjected to moisture absorption and heat generation. (B) and an elastic yarn (C), the hygroscopic and heat-generating fabric containing 5 to 40% by mass of the cellulose-based fiber (a1) subjected to the hygroscopic heat-generating process when the fabric is 100% by mass, and the cellulose-based fiber The total amount (A+B) is 85-97% by weight and the elastic thread (C) is 3-15% by weight. As a result, it is possible to provide a moisture-absorbing and heat-generating garment that is imparted with appropriate moisture-absorbing and heat-generating properties and that does not easily lose its shape even after repeated washing.

また、吸湿発熱加工したセルロース系繊維（ａ１）を５～４０質量％混合することにより、吸湿発熱加工時のセルロース系繊維の傷みを未処理セルロース系繊維により補うことができる。生地を１００質量％としたとき、吸湿発熱加工したセルロース系繊維（ａ１）は５～３０質量％が好ましく、さらに好ましくは６～２０質量％である。また、コットン合計量（Ａ＋Ｂ）：弾性糸の比率は質量％で８８：１２～９４：６が好ましく、さらに好ましくは９０：１０～９５：５である。 In addition, by mixing 5 to 40% by mass of the cellulose-based fiber (a1) that has undergone the moisture absorption and heat generation process, damage to the cellulose-based fiber during the moisture absorption and heat generation process can be compensated for by the untreated cellulose-based fiber. Based on 100% by mass of the fabric, the content of the cellulose-based fiber (a1) subjected to the heat-absorbing and exothermic treatment is preferably 5 to 30% by mass, more preferably 6 to 20% by mass. Further, the ratio of the total amount of cotton (A+B):elastic yarn is preferably 88:12 to 94:6, more preferably 90:10 to 95:5 in mass %.

A commonly used elastic thread is a polyurethane thread.

弾性糸は、例えば緯編み生地、丸編み生地の場合、スパンデックス裸糸をループ糸の添え糸として入れることが好ましく、経編み生地の場合、スパンデックス裸糸を挿入組織、又は緯糸挿入によって入れる。いわゆるインナー衣料の場合は、通常丸編みが採用され、弾性糸特にポリウレタン弾性糸はループ糸の添え糸として用いられる。ポリウレタン弾性糸は、通常２０～４０decitexの糸が２．５倍程度に引き延ばされた状態で添え糸として挿入される。 For example, in the case of weft-knitted fabrics and circular-knitted fabrics, it is preferable to insert bare spandex yarns as attachment yarns for loop yarns. In the case of so-called inner garments, circular knitting is usually employed, and elastic yarns, especially polyurethane elastic yarns, are used as attachment yarns for loop yarns. The polyurethane elastic thread is usually inserted as a splint thread in a state in which a thread of 20 to 40 decitex is stretched about 2.5 times.

本発明の吸湿発熱性生地で縫製した衣料は、弾性糸が身体の周囲方向に配置されている。いわゆるワンウェイストレッチ生地が好ましい。身体の周囲方向とは、胴体の周囲方向、及び腕の周囲方向のことである。これにより着心地が良く、洗濯を繰り返しても型崩れしにくいインナー衣料となる。この衣料は、シャツ又はパンツが好ましい。本発明のインナー衣料はコットンが８５質量％以上、好ましくは８８質量％以上、さらに好ましくは９０質量％以上の主要繊維であり、肌にやさしいインナー衣料である。 In the garment sewn from the hygroscopic and heat-generating fabric of the present invention, elastic threads are arranged in the circumferential direction of the body. So-called one-way stretch fabrics are preferred. The circumferential direction of the body is the circumferential direction of the torso and the circumferential direction of the arms. As a result, the inner garment is comfortable to wear and does not lose its shape even after repeated washing. This garment is preferably a shirt or pants. The inner garment of the present invention contains 85% by mass or more, preferably 88% by mass or more, more preferably 90% by mass or more of cotton as the main fiber, and is gentle on the skin.

次に本発明の製造方法について、セルロース系繊維としてコットン（天然セルロース繊維）を使った場合を例示して説明する。紡績用コットンスライバーに対して、連続法の場合は窒素雰囲気下で電子線を照射し、コットン繊維表面にラジカルを発生させ、直後に連続的にエチレン性不飽和二重結合を含む化合物をコットン繊維の表面に接触させる。電子線照射直後にエチレン性不飽和二重結合を含む化合物をコットン繊維の表面に接触させるのは、電子線照射により発生したラジカルを減衰させないためである。ラジカルは時間とともに減衰する傾向が高いので、電子線照射直後にエチレン性不飽和二重結合を含む化合物をコットン繊維の表面に接触させるのが好ましい。また、電子線照射後、エチレン性不飽和二重結合を含む化合物をコットン繊維の表面に接触させることを連続的に行うのは、エチレン性不飽和二重結合を含む化合物をコットン繊維の表面に発生したラジカルに効果的に接触できるため、好ましい。さらに、連続的に行うことは、長尺物の紡績用スライバーを処理するのに好都合である。さらに、窒素雰囲気下で電子線を照射すると、発生したラジカルが失活しにくいので好ましい。 Next, the production method of the present invention will be described by exemplifying the case where cotton (natural cellulose fiber) is used as the cellulose fiber. In the continuous method, the cotton sliver for spinning is irradiated with an electron beam in a nitrogen atmosphere to generate radicals on the surface of the cotton fiber, and immediately after that, a compound containing an ethylenically unsaturated double bond is continuously added to the cotton fiber. surface. The reason why the compound containing an ethylenically unsaturated double bond is brought into contact with the surface of the cotton fiber immediately after the electron beam irradiation is to prevent the radicals generated by the electron beam irradiation from attenuating. Since radicals tend to attenuate with time, it is preferable to bring the compound containing an ethylenically unsaturated double bond into contact with the surface of the cotton fiber immediately after electron beam irradiation. After the electron beam irradiation, the compound containing the ethylenically unsaturated double bond is continuously brought into contact with the surface of the cotton fiber. It is preferable because it can effectively contact the generated radicals. Furthermore, the continuous operation is advantageous for processing long spinning sliver. Furthermore, it is preferable to irradiate electron beams in a nitrogen atmosphere because the generated radicals are less likely to be deactivated.

エチレン性不飽和二重結合を含む化合物をコットン繊維の表面に接触させる方法は、浸漬法又はスプレ－法などいかなる方法でも良い。例えば、エチレン性不飽和二重結合を含む化合物を水溶液に調製して、スライバーを浸漬させるかまたは、スライバーにスプレーして、付与するのが好ましい。 Any method such as a dipping method or a spray method may be used to bring the compound containing an ethylenically unsaturated double bond into contact with the surface of the cotton fibers. For example, it is preferable to prepare an aqueous solution of a compound containing an ethylenically unsaturated double bond and apply it by immersing the sliver or spraying it onto the sliver.

本発明においては、前記処理後の紡績用スライバーとそれ以外の未処理スライバーを混紡し精紡することにより、吸湿発熱機能を有する紡績糸が得られる。混紡は通常はダブリング工程の入る練条工程が好ましい。しかし、梳綿工程（カード）、粗紡工程、精紡工程でも可能であり、ウエブ、スライバー、フリース、粗紡糸を複数本引き揃え、所定倍率引き伸ばすことにより混紡できる。粗紡工程や精紡工程では、撚り掛けする際に構成繊維のマイグレーションにより混紡できる。さらには、前記処理後の紡績用スライバーを混打綿工程まで戻して所望の混紡割合にすることも可能である。 In the present invention, a spun yarn having a hygroscopic and heat-generating function is obtained by blending and spinning the sliver for spinning after the treatment and the other untreated sliver. For blend spinning, a drawing process including a doubling process is usually preferred. However, the carding process (carding process), roving process, and spinning process are also possible, and a plurality of webs, sliver, fleece, and roving yarns can be arranged and blended by drawing them at a predetermined ratio. In the roving process and the spinning process, blending can be achieved by migration of the constituent fibers during twisting. Furthermore, it is also possible to return the sliver for spinning after the above-mentioned treatment to the blending step to achieve a desired blending ratio.

前記吸湿発熱加工したコットンと吸湿発熱加工していないコットンを混紡した後は、常法にしたがい混紡紡績糸（Ａ）とする。また、吸湿発熱加工していないコットンの紡績糸も常法にしたがい紡績糸（Ｂ）とする。前記混紡紡績糸（Ａ）と紡績糸（Ｂ）と弾性糸（Ｃ）を所定量使用して吸湿発熱性生地とする。この生地は常法にしたがい晒、染色、柔軟仕上げなどの後加工することは任意である。 After blending the cotton treated with moisture absorption and heat generation and the cotton not treated with moisture absorption and heat generation, a blended spun yarn (A) is obtained according to a conventional method. A spun yarn of cotton that has not been subjected to moisture absorption and heat generation treatment is also used as the spun yarn (B) according to a conventional method. Predetermined amounts of the blended spun yarn (A), spun yarn (B) and elastic yarn (C) are used to form a hygroscopic and heat-generating fabric. This fabric may optionally be subjected to post-processing such as bleaching, dyeing, and softening in accordance with conventional methods.
