Description
【０００１】
【発明の属する分野】
本発明は立体構造編み地に関し、詳しくは、持続的な保温性に優れた立体構造編み地に関する。
【０００２】
【従来の技術】
より積極的に人体を暖めることを意図して、アクリル酸系の吸湿発熱繊維を用いた衣料（特許第２０２８４６７号明細書）、セルロースに水溶性ビニル重合化合物を導入した吸湿発熱性セルロース繊維を用いた衣料（特許第２８９８６２３号明細書）等が知られている。
しかしながら、これらアクリル酸系の吸湿発熱繊維および吸湿発熱性セルロース繊維は吸湿発熱性を有するものの、これらの繊維を用いた衣料は、一時的には保温能力を発揮するが、持続的な人体からの熱の逃散阻止能力に欠けていた。
【０００３】
【発明が解決しようとする課題】
本発明はかかる欠点を解決し、持続的な人体からの熱の逃散阻止能力の優れた布帛を提供することを目的とするものである。
【０００４】
【課題を解決するための手段】
本発明者らは、熱の逃散阻止能力と布帛構造について検討した結果、特定の繊維構造体を用いることにより本発明の目的が達成されることを見出し本発明に到達した。
即ち本発明は、表裏二層の編地と該二層の編地を連結する連結糸から構成された立体編物であって、連結糸に、２０℃、４０％ＲＨ（相対湿度）から２０℃、９０％ＲＨに変化させた時の吸湿発熱量が１５Ｊ／ｇ以上である吸湿発熱性繊維を用いてなることを特徴とする立体構造編み地である。ここで、ＲＨは相対湿度である。
【０００５】
本発明においては、表裏二層の編地を構成する繊維としては、公知の各種繊維を用いることができ、例えば綿、羊毛等の天然繊維や、キュプラ、レーヨン、アセテート、ポリオレフィン、アクリル、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリトリメチレンテレフタレート等のポリエステル、ナイロン６、ナイロン６６等の人造繊維（長繊維、短繊維）があり、必要に応じて同種又は異種繊維の組み合わせ、さらには長繊維同志、短繊維同志、並びにこれらを組合せて用いることができるが、保温性の観点からは短繊維が好ましい。例えば、特に衣料用の場合、快適性付与を目的に、Ｗ断面等の異型断面糸や極細繊維（単糸ｄｔｅｘが１．１ｄｔｅｘ以下）を用いることで吸水速乾性を付与することもできる。
【０００６】
本発明では、連結糸として２０℃、４０％ＲＨから２０℃、９０％ＲＨに変化させた時の吸湿発熱量が１５Ｊ／ｇ以上である吸湿発熱性繊維を用いることに特徴がある。
かかる吸湿発熱性繊維は、着用者の皮膚表面から不感蒸泄により出される気体状の汗や、液体状の汗を吸着して発熱するものであり、具体例としては、ポリノジックレーヨン、ビスコースレーヨン、キュプラ、精製セルロース繊維等のセルロース繊維や羊毛（吸湿発熱量が１６Ｊ／ｇ）や、カルボキシル基又はアミノ基を有する水溶性ビニル化合物が導入されたセルロース繊維（吸湿発熱量が３２Ｊ／ｇ）、特許第２０２８４６７号明細書に開示されたアクリル酸系吸湿発熱性繊維（吸湿発熱量が２６Ｊ／ｇ）などが好ましい。
【０００７】
吸湿発熱性繊維の単糸繊度は、好ましくは０．１〜５ｄｔｅｘ、より好ましくは０．５〜３ｄｔｅｘである。繊維の形態は、長繊維よりも短繊維の方が保温性の観点から好ましい。又、長繊維でも仮撚糸等の嵩高加工糸が好ましい。
吸湿発熱性繊維は、単独で用いてもよいが、好ましくは３０質量％以上、特に４０質量％以上、７０質量％以下の範囲内で疎水性の合成繊維と混用してもよく、混用した糸条の吸湿発熱量が４．８Ｊ／ｇ以上であることが好ましい。混用形態は、混紡やサイロスパン、サイロフィル、ホロースピンドル等の複合紡績、混繊、複合仮撚（引き揃え、位相差、伸度差等）や２フィードの流体噴射加工等の複合嵩高加工等があるが、紡績糸の形態が本発明の目的達成上好ましい。
【０００８】
疎水性の合成繊維としては、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリトリメチレンテレフタレート等のポリエステル系繊維、ナイロン６、ナイロン６６等のポリアミド系繊維、アクリル系繊維、ポリビニルアルコール系繊維、ポリオレフィン系繊維があり、単糸繊度は、好ましくは０．１〜５ｄｔｅｘ、より好ましくは０．１〜３ｄｔｅｘ、さらに好ましくは０．１〜１．３ｄｔｅｘ、特に好ましくは０．５〜１．１ｄｔｅｘである。単糸繊度がこの範囲であると、繊維内空隙の径が小さくなるため、通気抵抗が高くなり、デッドエアーが多くなって、熱の逃散阻止能力が向上すると共に、吸湿発熱性繊維の吸湿発熱量を長期間持続させることができる。単糸繊度が５ｄｔｅｘを越えると、繊維内空隙の径が大きくなり保温性が低下する傾向にある。繊維の形態は短繊維が好ましいが、長繊維でも仮撚糸等の嵩高加工糸が好ましい。
【０００９】
本発明において、吸湿発熱性繊維を単独又は混用して連結糸に用いる際は、紡績糸（複合紡績糸）の形態では、撚り係数は低い方が繊維内空隙を保ち保温性を高める目的で好ましく、単糸、双糸、３本撚り糸などであってもよい。紡績糸を追撚したものであっても良いが加撚数は８００Ｔ／ｍ以下、特に５００Ｔ／ｍ以下が繊維内空隙を保つために適する。長繊維では、無撚又は８００Ｔ／ｍ以下、特に５００Ｔ／ｍ以下の甘撚が好ましい。
又、連結糸全てに吸湿発熱性繊維を用いるのが最適であるが、質量％で好ましくは３０％以上、特に５０％以上、さらに７０％以上が吸湿発熱性繊維で構成されているのが好ましい。
尚、表裏二層の編地を構成する繊維にも、必要に応じて吸湿発熱性繊維を単独又は混用した糸条を用いてもよい。
【００１０】
本発明の立体構造編み地は２列の針列を有するダブルラッシェル機、ダブル丸編機、横編機等で編成することができる。表面と裏面の組織としては、平編の基本組織、又はタック編、浮編、片畦編、レース編、添糸編等の変化組織のいずれであってもよい。又、表裏面の編地の変化組織に針抜きを組み合わせてもよい。編機のゲージは使用目的によって適宜選定すれば良く、１０〜４０ゲージが使用可能である。
連結糸は、表裏編地中にループ状の編み目を形成してもよく、表裏編地にタック組織状に引っかけた構造でもよく、要は表裏編地を結び付けておればよく、必要に応じて連結糸を傾斜して配置したり、トラス状やＸ状に交叉して配置してもよい。
【００１１】
立体構造編み地の厚さや目付は希望に応じて適宜選定すればよく、例えば、厚みは２〜２０ｍｍ程度、好ましくは３〜１０ｍｍ程度、目付は８０ｇ／ｍ２ 〜１２００ｇ／ｍ２ 程度、好ましくは１００〜１２００ｇ／ｍ２ 程度が好ましい。又、立体編地は必要に応じて所望のサイズに裁断したり、又は、裁断後の編地片を縫製又は熱成形により所望の形状にして用いてもよい。
本発明の立体構造編み地は、衣料、毛布、スカーフ、マフラー、帽子、手袋、靴下、座布団などに使用することにより、人の体温を積極的に維持し守るために有効に働く。また布帛、および縫製品の一部に用いたものであってもよい。

本発明は、保温性に優れた立体構造編み地を提供する。[0001]
[Field of the Invention]
The present invention relates to a three-dimensional knitted fabric, and more particularly, to a three-dimensional knitted fabric excellent in sustained heat retention.
[0002]
[Prior art]
In order to more positively warm the human body, clothing using acrylic acid-based moisture-absorbing heat-generating fibers (Japanese Patent No. 2028467), and moisture-absorbing heat-generating cellulose fibers obtained by introducing a water-soluble vinyl polymer compound into cellulose are used. Clothing (Japanese Patent No. 2898623) and the like are known.
However, although these acrylic acid-based moisture-absorbing and heat-generating fibers and moisture-absorbing and heat-generating cellulose fibers have moisture-absorbing and heat-generating properties, clothing using these fibers temporarily exerts a heat-retaining ability, but is continuously used by humans. It lacked the ability to prevent heat from escaping.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to solve such a drawback and to provide a fabric excellent in the ability to prevent heat from escaping from the human body continuously.
[0004]
[Means for Solving the Problems]
The present inventors have studied the ability to prevent heat from escaping and the fabric structure, and as a result, have found that the object of the present invention can be achieved by using a specific fiber structure, and have reached the present invention.
That is, the present invention relates to a three-dimensional knitted fabric composed of a two-layered knitted fabric and a connecting yarn for connecting the two-layered knitted fabric, wherein the connecting yarn is provided at 20 ° C. and 40% RH (relative humidity) to 20 ° C. And a three-dimensional knitted fabric characterized by using moisture-absorbing and heat-generating fibers having a heat-absorbing heat generation value of 15 J / g or more when changed to 90% RH. Here, RH is a relative humidity.
[0005]
In the present invention, known fibers can be used as the fibers constituting the front and back two-layer knitted fabric, such as natural fibers such as cotton and wool, cupra, rayon, acetate, polyolefin, acrylic, and polyethylene terephthalate. Polyester such as polybutylene terephthalate and polytrimethylene terephthalate; and artificial fibers (long fibers and short fibers) such as nylon 6 and nylon 66. If necessary, a combination of the same or different fibers, and further, a combination of long fibers and short fibers Fibers can be used in combination with each other, or short fibers are preferable from the viewpoint of heat retention. For example, in the case of clothing, in particular, for the purpose of imparting comfort, water-absorbing quick-drying properties can also be imparted by using a yarn having an irregular cross section such as a W cross section or an ultrafine fiber (single yarn dtex is 1.1 dtex or less).
[0006]
The present invention is characterized in that a moisture-absorbing and heat-generating fiber having a moisture-absorbing heat value of 15 J / g or more when the temperature is changed from 20 ° C. and 40% RH to 20 ° C. and 90% RH is used as the connecting yarn.
Such moisture-absorbing and heat-generating fibers absorb gaseous sweat and liquid sweat generated from the skin surface of the wearer by insensitive evaporation and generate heat, and specific examples thereof include polynosic rayon and viscose rayon. , Cupra, cellulose fiber such as purified cellulose fiber and wool (moisture absorption calorific value of 16 J / g), and cellulose fiber into which a water-soluble vinyl compound having a carboxyl group or an amino group is introduced (moisture absorption calorific value of 32 J / g), Acrylic acid-based moisture-absorbing and heat-generating fibers disclosed in Japanese Patent No. 2028467 (having a moisture-absorbing heat value of 26 J / g) are preferred.
[0007]
The single yarn fineness of the moisture-absorbing and heat-generating fiber is preferably 0.1 to 5 dtex, more preferably 0.5 to 3 dtex. Regarding the fiber form, short fibers are more preferable than long fibers from the viewpoint of heat retention. Also, bulky processed yarns such as false twisted yarns are preferable for long fibers.
The moisture-absorbing heat-generating fiber may be used alone, but may be mixed with a hydrophobic synthetic fiber in a range of preferably 30% by mass or more, particularly 40% by mass or more and 70% by mass or less. It is preferable that the moisture absorption heat generation value of the strip is 4.8 J / g or more. The mixed form includes compound spinning such as mixed spinning, silospan, silofil, and hollow spindle, mixed fiber, compound false twisting (pulling, phase difference, elongation difference, etc.) and compound bulking such as two-feed fluid injection processing. However, a spun yarn form is preferred for achieving the object of the present invention.
[0008]
Examples of hydrophobic synthetic fibers include polyester fibers such as polyethylene terephthalate, polybutylene terephthalate, and polytrimethylene terephthalate; polyamide fibers such as nylon 6, nylon 66; acrylic fibers; polyvinyl alcohol fibers; and polyolefin fibers. The single fiber fineness is preferably 0.1 to 5 dtex, more preferably 0.1 to 3 dtex, further preferably 0.1 to 1.3 dtex, and particularly preferably 0.5 to 1.1 dtex. When the single-fiber fineness is within this range, the diameter of the voids in the fiber becomes small, so that the ventilation resistance increases, the dead air increases, the ability to prevent heat from escaping improves, and the moisture-absorbing heat of the heat-absorbing heat-generating fiber increases. The amount can be long lasting. If the single-fiber fineness exceeds 5 dtex, the diameter of the voids in the fiber tends to increase, and the heat retention tends to decrease. The form of the fibers is preferably short fibers, but even long fibers are preferably bulky processed yarns such as false twisted yarns.
[0009]
In the present invention, when the moisture-absorbing heat-generating fiber is used alone or in combination as a connecting yarn, in the form of a spun yarn (composite spun yarn), a lower twist coefficient is preferable for the purpose of maintaining the voids in the fiber and increasing the heat retention. , A single yarn, a double yarn, a three-ply yarn, or the like. A spun yarn may be additionally twisted, but a twist number of 800 T / m or less, particularly 500 T / m or less is suitable for maintaining a void in the fiber. For long fibers, non-twisting or sweet twisting of 800 T / m or less, particularly 500 T / m or less is preferred.
It is optimal to use moisture-absorbing and heat-generating fibers for all of the connecting yarns, but it is preferable that 30% or more, particularly 50% or more, and even 70% or more by mass% be composed of moisture-absorbing and heat-generating fibers. .
It should be noted that, as the fibers constituting the two-layered knitted fabric, yarns in which moisture-absorbing and heat-generating fibers are used alone or in combination may be used as necessary.
[0010]
The three-dimensional knitted fabric of the present invention can be knitted by a double Raschel machine, a double circular knitting machine, a flat knitting machine, or the like having two rows of needles. The structure of the front surface and the back surface may be any of a basic structure of flat knitting, or a changed structure such as tack knitting, floating knitting, single-row knitting, lace knitting, and spun knitting. Further, a needle punch may be combined with the changed structure of the knitted fabric on the front and back surfaces. The gauge of the knitting machine may be appropriately selected depending on the purpose of use, and 10 to 40 gauges can be used.
The connecting yarn may form a loop-shaped stitch in the front and back knitted fabric, and may have a structure in which the front and back knitted fabric is hooked in a tack structure.In short, the front and back knitted fabric may be connected, if necessary. The connecting yarns may be arranged obliquely, or may be arranged crosswise in a truss shape or an X shape.
[0011]
The thickness and basis weight of the three-dimensional structure knitted fabric may be appropriately selected depending on the desired thickness of, for example, about 2 to 20 mm, preferably about 3 to 10 mm, basis weight 80g / m 2 ~1200g / m 2 approximately, preferably About 100 to 1200 g / m 2 is preferable. The three-dimensional knitted fabric may be cut into a desired size as needed, or the cut knitted fabric piece may be used in a desired shape by sewing or thermoforming.
The three-dimensional knitted fabric of the present invention works effectively for maintaining and protecting human body temperature by using it for clothing, blankets, scarves, mufflers, hats, gloves, socks, cushions and the like. Further, it may be used for a part of a fabric or a sewn product.
