Description
本発明は、人体皮膚に対する接触冷感に優れた編地及び該編地を用いた肌着に関する。 TECHNICAL FIELD The present invention relates to a knitted fabric excellent in contact cooling with human skin and an underwear using the knitted fabric.
編織物に接触冷感を付与する方法としては、天然繊維や合成繊維からなる編織物に、接触冷感効果を有する機能剤などを固着させる、或いは接触冷感性能を有する繊維で構成された糸を用いて製編織を行う等の方法が採用されてきた。 As a method for imparting a contact cooling sensation to a knitted fabric, a yarn composed of fibers having a contact cooling sensation performance or a functional agent having a contact cooling sensation effect is fixed to a knitted fabric made of natural fibers or synthetic fibers A method such as knitting and weaving using a slab has been adopted.
繊維材料に機能材を固着させるものとしては、特開２００２-２３５２７８号では、吸水性ポリマーを内包した多孔質無機粉末粒子を繊維に把持させたもの（特許文献１）、特開２００４―３３２１６８号では、分子量が２０００以下のポリオール類をセルロース繊維重量に対して２〜３０重量％を含浸、乾燥、硬化して固着させた変性セルロース系繊維（特許文献２）、特開２００６-１６１２２６号では融点が２５〜３７℃であり、潜熱の放出・吸収を伴って可逆的に固液相転移する潜熱蓄熱材を封入してなるマイクロカプセルが繊維に固着されてなることを特徴とする接触冷感性能を有する繊維構造物が開示されている（特許文献３）。 As for fixing a functional material to a fiber material, in Japanese Patent Laid-Open No. 2002-235278, porous inorganic powder particles containing a water-absorbing polymer are held by a fiber (Patent Document 1), Japanese Patent Laid-Open No. 2004-332168. Then, a modified cellulose fiber impregnated with 2 to 30% by weight of a polyol having a molecular weight of 2000 or less based on the weight of the cellulose fiber, dried and cured (Patent Document 2), and melting point in JP-A No. 2006-161226 Is a temperature of 25 to 37 ° C., and a microcapsule encapsulating a latent heat storage material that reversibly undergoes a solid-liquid phase transition with the release and absorption of latent heat is fixed to the fiber, and has a cooling contact sensation performance The fiber structure which has this is disclosed (patent document 3).
また、使用する繊維或いは構造に特徴のあるものとしては、特開２００４-２７００７５号では、ポリエーテルブロックアミド共重合体である熱可塑性エラストマーを含有し、Ｑ-ｍａｘ値０．２Ｊ/ｓｅｃ/ｃｍ2以上であることを特徴とする接触冷感に優れた繊維を使用したものが提案されており（特許文献４）、また、特開２００８−３０８８０４号では、単層又は複層で形成されている織物からなる衣料用布帛であって、裏面が主として仮撚加工が施されたフィラメントであり、親水性のエチレンビニルアルコール樹脂を少なくとも表層に含む捲縮繊維糸で形成されていることにより、接触冷感と吸汗性に加えて多量発汗時のべたつきを抑え、快適性の高い衣料用布帛及びこれを用いた衣類も開示されている（特許文献５）。上記のような機能剤を固着させたものは衣料に使用した場合、湿潤時の不快感を防止することができ、かつ、優れた風合いや肌触りを付与するとされている。 Further, as a characteristic of the fiber or structure to be used, JP-A-2004-270075 contains a thermoplastic elastomer which is a polyether block amide copolymer and has a Q-max value of 0.2 J / sec / cm. A fiber using a fiber having excellent contact cooling sensation characterized by being 2 or more has been proposed (Patent Document 4), and Japanese Patent Application Laid-Open No. 2008-308804 is formed of a single layer or multiple layers. A fabric for clothing comprising a woven fabric having a back surface mainly formed by false twisting and formed by crimped fiber yarns containing at least a hydrophilic ethylene vinyl alcohol resin in the surface layer, In addition to the cool feeling and sweat-absorbing property, there is also disclosed a cloth for clothing having high comfort by suppressing stickiness at the time of sweating a large amount and clothing using the same (Patent Document 5). It is said that when a functional agent fixed as described above is used in clothing, it is possible to prevent discomfort when wet and to impart an excellent texture and touch.
しかしながら上記したような機能剤を繊維もしくは繊維材料表面に固着させたものが充分な接触冷感を得るためには、大量の薬剤を含有させる必要があり、風合いや肌触りが悪くなるという欠点があった。また、機能繊維を使用する場合は、理論的には接触冷感が期待できるものの、いまだその性能は充分なものではなかった。 However, in order to obtain sufficient contact cooling sensation in which the functional agent as described above is fixed to the surface of the fiber or the fiber material, it is necessary to contain a large amount of the drug, and there is a disadvantage that the texture and the touch become worse. It was. Also, when functional fibers are used, theoretically, a feeling of cool contact can be expected, but the performance is still not sufficient.
本発明は、編糸が綿１００％、又は綿／再生セルロース混紡糸よりなる編地であって、接触冷感性能Ｑ-ｍａｘ値が０．３Ｗ/ｃｍ2以上の肌着用編地を提供することを目的とする。
これまで接触冷感機能を有する薬剤を使用せず、綿又は綿／再生セルロース混紡素材固有の風合いや肌触りが良好で、接触冷感機能Ｑ-ｍａｘ値が０．３Ｗ/ｃｍ2以上の性能を持つ綿１００％、又は綿／再生セルロース混紡糸よりなる肌着はなかった。そこで、本発明では接触冷感に優れた綿１００％、又は綿／再生セルロース混紡糸編地を得る方法として、シルケット加工によって繊維自体の吸湿性能を向上させて水分率を高めることで生地の吸熱性能を高め、更に糸でのガス焼きによる毛羽除去、編地のバイオ加工を行って生地の毛羽を抑えて平滑にすることで、肌との接触面積を増大させ、肌から生地へ熱が伝わり易くし、上記接触冷感機能の向上を達成した。尚、本発明で述べるＱ-ｍａｘ値が０．３Ｗ/ｃｍ2以上とは、Ｑ-ｍａｘ値が一定面積、一定質量の熱板に所定の熱を蓄え、これが試料表面に接触した直後、蓄えられた熱量が低温側の試料に移動する熱流量のピーク値である。したがって、Ｑ-ｍａｘ値は、着衣したときに試料に奪われる体温を体現していると考えられる。したがって、Ｑ-ｍａｘ値が大きいほど接触冷感性能が高いとされる。
The present invention provides a skin-wearing knitted fabric in which the knitting yarn is made of 100% cotton or a cotton / regenerated cellulose blended yarn, and has a contact cooling feeling performance Q-max value of 0.3 W / cm 2 or more. For the purpose.
So far, no chemicals that have a contact cooling function have been used, the texture and feel unique to cotton or cotton / regenerated cellulose blends are good, and the contact cooling function Q-max value is 0.3 W / cm 2 or more. There was no underwear consisting of 100% cotton or cotton / regenerated cellulose blend yarn. Therefore, in the present invention, as a method for obtaining 100% cotton or cotton / regenerated cellulose blended yarn knitted fabric having excellent contact cooling feeling, the moisture absorption performance of the fabric itself is improved by improving the moisture absorption performance of the fiber itself by mercerization, thereby increasing the moisture absorption. By improving the performance, removing fluff by gas firing with yarn and bio-processing the knitted fabric, the fabric fluff is suppressed and smoothed, increasing the contact area with the skin and transferring heat from the skin to the fabric The contact cooling feeling function was improved. The Q-max value described in the present invention is 0.3 W / cm 2 or more. When the Q-max value is stored in a hot plate having a constant area and a constant mass, the heat is stored immediately after contacting the sample surface. This is the peak value of the heat flow rate at which the amount of heat transferred to the low temperature sample. Therefore, it is considered that the Q-max value embodies the body temperature taken away by the sample when wearing clothes. Therefore, the larger the Q-max value is, the higher the contact cooling feeling performance is.
本発明は、綿１００％よりなる糸、又は綿／再生セルロース混紡糸よりなる糸を編成して得られる、接触冷感性能がＱ-ｍａｘ０．３Ｗ/ｃｍ2以上である接触冷感性能に優れた編地に関する。接触冷感性能は、上記の測定法によって得られた値である。
接触冷感性能がＱ-ｍａｘ０．３Ｗ/ｃｍ2以上である接触冷感性能に優れた編地は、綿１００％よりなる糸、又は綿／再生セルロース混紡糸よりなる糸を、ガス焼きして毛羽を除去して糸の状態でシルケット加工をして編地とするか、またはガス焼きして毛羽を除去した糸を編地に編成後編地にシルケット加工を行った後に、編地をバイオ加工することによって得られる。更に、綿１００％よりなる糸、又は綿／再生セルロース混紡糸よりなる糸をガス焼きして毛羽を除去し、ついでシルケット加工を行って得た糸を編成して編地となし、該編地に再度シルケット加工を行った後にバイオ加工することにより、接触冷感性能がより優れた編地を得る。編地の編成はフライス地として編成することが好ましく、編地は肌着として使用することができる。
The present invention is excellent in the contact cooling feeling performance obtained by knitting a yarn made of 100% cotton or a yarn made of cotton / regenerated cellulose blend yarn and having a cooling contact feeling performance of Q-max 0.3 W / cm 2 or more. about the other knitted fabric. The contact cooling sensation performance is a value obtained by the above measurement method.
A knitted fabric having a contact cooling feeling performance of Q-max 0.3 W / cm 2 or more and excellent contact cooling feeling performance is obtained by gas firing a yarn made of 100% cotton or a yarn made of cotton / regenerated cellulose blend yarn. The fluff is removed and mercerized in the state of yarn to make a knitted fabric, or the yarn from which the fluff has been removed by gas baking is knitted into the knitted fabric, and then the knitted fabric is processed into the knitted fabric, and then the knitted fabric is bio-processed It is obtained by doing. Furthermore, a yarn made of 100% cotton or a yarn made of cotton / regenerated cellulose blended yarn is gas-fired to remove fluff, and then the yarn obtained by mercerization is knitted to form a knitted fabric. The knitted fabric with better contact cooling performance is obtained by performing the bioprocessing after the mercerization is performed again. The knitted fabric is preferably knitted as a milled fabric, and the knitted fabric can be used as an underwear.
本発明による肌着用編地は、従来品に見られるように綿素材に対して、各種薬剤を使用して製品素材を加工するか、もしくは、吸水性、蓄熱性を有する微粒子を繊維に付着させたり、綿以外の機能性繊維材料を混合したりして接触冷感を高めるものではなく、従来知られている技術を組み合わせることにより、接触冷感性を高めＱ-ｍａｘ値が０．３Ｗ/ｃｍ2以上の肌触りの良い肌着用編地を得ることが出来たものである。
このように、本発明の肌着用編地は、素材表面に何等の異成分が存在せず、編地が肌に密接して身体表面の熱や汗を吸収するよう構成されているので、着心地が良く安心して着用することができる肌着用素材である。
The skin-wearing knitted fabric according to the present invention is made by processing various kinds of chemicals on the cotton material as seen in conventional products, or by attaching fine particles having water absorption and heat storage properties to the fiber. Or by mixing functional fiber materials other than cotton to improve the contact cooling feeling, combining the conventionally known techniques to increase the contact cooling feeling and the Q-max value is 0.3 W / cm It was possible to obtain a skin-wearing knitted fabric having a touch of 2 or more.
Thus, the skin-wearing knitted fabric of the present invention is configured so that there are no different components on the material surface and the knitted fabric is in close contact with the skin and absorbs heat and sweat on the body surface. It is a skin-wearing material that is comfortable and can be worn with peace of mind.
本発明は、綿１００％よりなる糸、又は綿／再生セルロース混紡糸よりなる糸を使用する。糸の使用番手は細番手のものが良く、好ましくは双糸で番手４０／２以上、更に好ましくは番手６０／２以上のものを用いる。本発明の製造工程においては、まず、原糸を常法によりガス焼きして毛羽を除去し、皮膚面への接触を良好とする。ついでシルケット加工を行うが、この処理は、糸の状態で連続的に、又は綛の状態でシルケット加工を行った後、編成して編地とするか、又は毛羽を除去後、糸を編成して編地にシルケット加工を行う。 In the present invention, yarn made of 100% cotton or yarn made of cotton / regenerated cellulose blend yarn is used. The yarn count used is fine, preferably twin yarn with a count of 40/2 or more, more preferably a count of 60/2 or more. In the production process of the present invention, first, the raw yarn is gas-baked by a conventional method to remove fluff and to make good contact with the skin surface. Next, mercerizing is performed. This process is performed continuously in the state of the yarn or after the mercerization in the state of the heel, and then knitted to form a knitted fabric, or after removing the fluff, the yarn is knitted. And mercerize the knitted fabric.
更に、糸の状態でシルケット加工を行った後、編地に編成後再度シルケット加工を行うことにより、より接触冷感性の高い編地を得ることが出来る。シルケット加工は、通常の条件によりＮａＯＨ処理、一次絞り、温水洗浄、及び二次絞り等の処理を行う。シルケット加工により、苛性ソーダ液によって綿糸は膨潤して繊維断面が円形に近づき、表面が平滑になると同時に吸湿性も向上する。編地の編成においては、肌着とした場合の肌への密着性を大とする緻密な編地とすることが好ましく、天竺、スムース、フライス編みが適当であり、特にフライス編みとして編成するのが好ましい。 Furthermore, after performing mercerization in the state of yarn, knitting to the knitted fabric and then performing mercerization again, a knitted fabric with higher contact cooling can be obtained. In the mercerizing process, processing such as NaOH treatment, primary drawing, warm water washing, and secondary drawing is performed under normal conditions. By the mercerizing process, the cotton yarn is swollen by the caustic soda solution, the fiber cross section approaches a circle, the surface becomes smooth, and at the same time the hygroscopicity is improved. In the knitting of the knitted fabric, it is preferable to use a dense knitted fabric that increases the adhesion to the skin when it is used as an undergarment. Tendon, smooth and milling are suitable, and in particular, knitting as milling. preferable.
シルケット加工を終えて編成され、又はシルケット加工を終えた編地は、ついでバイオ加工を行う。公知のセルロース分解酵素であるセルラーゼを使用し、処理温度、処理溶液のｐＨを適宜選択して処理を行う。温水での洗浄により繊維内に浸透した繊維分解酵素の機能を停止させる失活処理を行う。バイオ加工により、加工工程中で発生した編地のピリング及び毛羽立ちを除去し、平滑で滑らかな表面として肌と編地との接触面積を増大させ、肌から生地へ熱が移動する効果を高めることが出来た。本発明による編地について接触冷感性能を測定したところ、Ｑ-ｍａｘ値が０．３Ｗ/ｃｍ2以上の編地であった。前記のような処理を行うことによって得られた編地は、接触冷感性能が従来の編地に較べて格段に優れているので、この編地によって編成される肌着は、吸湿性、涼感に優れたものである。 The knitted fabric that has been knitted after the mercerization or finished the mercerization is then subjected to bioprocessing. A cellulase, which is a known cellulose-degrading enzyme, is used, and the treatment temperature and the pH of the treatment solution are appropriately selected for treatment. A deactivation treatment is performed to stop the function of the fiber-degrading enzyme that has penetrated into the fiber by washing with warm water. Bio-processing eliminates knitting pilling and fluff generated during the processing process, increases the contact area between the skin and the knitted fabric as a smooth and smooth surface, and enhances the effect of heat transfer from the skin to the fabric Was made. When the contact cooling sensation performance of the knitted fabric according to the present invention was measured, the knitted fabric had a Q-max value of 0.3 W / cm 2 or more. The knitted fabric obtained by performing the treatment as described above has much better contact cooling performance than conventional knitted fabrics, so the underwear knitted by this knitted fabric is hygroscopic and cool. It is excellent.

The measurement results on the processing conditions and performance of Samples 1 to 8 obtained by the above Examples , Reference Examples and Comparative Examples are shown in the following table.
上記のように、本発明によって得られる肌着用編地は、接触冷感性能がＱ-ｍａｘ０．３Ｗ/ｃｍ2以上である接触冷感に優れた編地である。本発明においては、毛羽を除去した糸、又は該糸を用いて編成されたフライス地にシルケット加工を行い、編地をバイオ加工することによって接触冷感性能がＱ-ｍａｘ０．３Ｗ/ｃｍ2以上である接触冷感に優れた編地が得られた。一方、比較例から明らかなように、シルケット加工、及びバイオ加工のいずれかのみを行っても、本発明による接触冷感性能効果を達成することができなかった。
次に、本発明肌着製品と、従来法による肌着製品について、８名の着用者による接触冷感着用官能試験を行った。
As described above, the underwear knitted fabric obtained by the present invention is a knitted fabric excellent in contact cooling feeling having a contact cooling feeling performance of Q-max 0.3 W / cm 2 or more. In the present invention, the contact cooling feeling performance is Q-max 0.3 W / cm 2 or more by performing mercerization on the yarn from which the fluff has been removed, or milling knitted using the yarn, and bio-processing the knitted fabric. A knitted fabric excellent in contact cooling feeling was obtained. On the other hand, as is clear from the comparative example, the contact cooling sensation performance effect according to the present invention could not be achieved even if only the mercerizing process or the bio-processing process was performed.
Next, for the underwear product of the present invention and the underwear product according to the conventional method, a contact cold feeling wearing sensory test was conducted by eight wearers.
一方、比較例１〜４で作成した編み地はＱ-ｍａｘ値が低く、吸湿性も低く、官能試験においても冷感を感じた被験者は少なかった。
On the other hand, the knitted fabrics produced in Comparative Examples 1 to 4 had a low Q-max value, low hygroscopicity, and few subjects felt cold feeling in the sensory test.
本発明による肌着用編地は、綿素材に対して各種薬剤を使用して製品素材を加工するか、綿以外の機能性繊維材料を混合したりして接触冷感を高めるものではなく、従来知られている技術を組み合わせることにより接触冷汗性能を高めた綿又は綿／再生セルロース混紡素材よりなる編地であるので着心地が良く、安心して着用することができる。 The skin-wearing knitted fabric according to the present invention is not intended to improve the feeling of contact cooling by processing product materials using various chemicals on cotton materials or mixing functional fiber materials other than cotton. Since it is a knitted fabric made of cotton or cotton / regenerated cellulose blend material with improved contact cold sweat performance by combining known techniques, it is comfortable to wear and can be worn with peace of mind.
