【０００１】
【発明の属する技術分野】
本発明は、保湿性、接触冷感に優れた変性セルロース系繊維に関する。
【０００２】
【従来の技術】
夏場などの暑い季節には、衣服等着用時の接触冷感が大きい衣類が好まれる。接触冷感は、衣類と皮膚との温度差、接触の程度、衣類の表面状態等種々の要因が関連しているが、一般的な傾向として、接触冷感は、繊維の保湿性と密接に関連しており、繊維の保湿性が高いと、そのような繊維で構成される衣類等は接触冷感も高くなる。水分は熱伝導率が高く、水分率が高くなると熱伝導性が上がるためである。本発明は、係る保水性の観点からセルロース繊維を変性し、同時に接触冷感特性に優れた変性セルロース繊維開発で生まれたものである。
【０００３】
接触冷感性繊維としては、例えば特許文献１、特許文献２あるいは特許文献３が知られている。
【０００４】
特許文献１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てなる繊維又は繊維製品が開示されている。

【０００８】
【発明が解決しようとする課題】
本発明は、従来技術とは全く異なる手段により、接触冷感に優れた変性セルロース系繊維を提供することを目的とする。
本発明は、セルロース系繊維表面を化学的に変性することにより、繊維の保湿性を高め、接触冷感特性を有する変性セルロース系繊維を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明は、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％固着させた変性セルロース系繊維に関する。
【００１０】
本発明の変性セルロース系繊維は、保湿性に優れ、衣類等に使用したときは接触冷感に優れている。
【００１１】
本発明が適用されるセルロース系繊維としては、特に限定なく、木綿、麻等の天然セルロース類、ビスコースレーヨン、銅アンモニア法レーヨン、ポリノジック等の再生セルロース、テンセル等の精製セルロースがいずれも対象となる。またこれらのセルロース系繊維と合成繊維（例えば、ポリエステル、ポリアミド等）、セルロース系繊維どうし、またはセルロース系繊維と動物性繊維（例えば、羊毛、シルク等）の混紡、混撚、交織、交編体としてのセルロース系繊維も加工の対象となる。
【００１２】
本発明においては、上記のセルロース系繊維に、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％固着させる。
【００１３】
本発明に使用できるポリオール類は、分子内に少なくとも２つの水酸基を有する化合物、例えばポリエチレングリコール、ポリプロピレングリコール、ジエチレングリコール、トリエチレングリコール、グリセリン、エリスリトール、キシリトール、ソルビトールが例示できる。これらの化合物の中でもポリエチレングリコールが保湿性及び接触冷感特性が特に優れており好ましい。
【００１４】
本発明で使用するポリオール類は、分子量約２０００以下で使用する。本発明において分子量とは重量平均分子量を意味している。分子量が２０００以上では、加工（変性）効果が少なく、また、得られる繊維の洗濯耐久性が不充分なものとなる。
【００１５】
ポリオール類のセルロース系繊維への固着は、セルロース系繊維とポリオール類を架橋剤で架橋することにより行う。架橋剤としてはグリオキザール系化合物、例えばジメチロールジヒドロキシエチレンウレア、ジメチロールプロピレンウレア、ジメチロールエチレンウレア、ジメチルジヒドロキシエチレンウレア及びこれらの変性物等またはエポキシ系化合物、例えばエチレングリコールジグリシジルエーテル、ポリエチレングリコールジグリシジルエーテル、グリセロールトリグリシジルエーテル、ポリグリセロールポリグリシジルエーテル等が使用できる。好ましくはジメチロールジヒドロキシエチレンウレア、ジメチルジヒドロキシエチレンウレアである。
【００１６】
ポリオール類のセルロース系繊維への固着量は、セルロース繊維重量に対して２〜３０重量％、好ましくは３〜２０重量％とする。固着量が２重量％より少ないと加工（変性）効果が不充分であり、３０重量％より多いと、加工（変性）変退色が著しくなり、染色堅牢度が不良なものとなってしまう。本発明において固着量は、次の式により求められる。
（加工後の絶乾重量−加工前の絶乾重量）／加工前の絶乾重量×１００（重量％）。
【００１７】
ポリオール類をセルロース系繊維へ固着させるには、セルロース系繊維に固着させたい量よりも多めのポリール類、架橋剤を水、アルコール等の溶媒とともに混合した溶液を、セルロース系繊維に含浸させ、乾燥、硬化（キュアリング）させればよい。このとき架橋剤は、ポリオール類重量に対して、０．１〜１００重量％を基準に添加すればよい。硬化は５０〜１８０℃、１０秒〜２０分程度行えばよい。
【００１８】
セルロース系繊維は、繊維の形態以外にも、織物、編物などの布帛、ワタ、糸、不織布または繊維製品等の形態で、上記処理を行ってもよい。
【００１９】
本発明の変性セルロース繊維は、保湿性、接触冷感特性に優れている。従って、例えば本発明の変性セルロース繊維を使用した衣類等は、接触冷感のある衣類となり、またタオルに使用したときは、水分保水性の良好な、しっとりとした接触感がよいタオルとすることができる。その他、冬期など乾燥した環境下では、肌に対して保湿効果のある肌着などに応用することができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a modified cellulosic fiber excellent in moisturizing property and contact coolness.
[0002]
[Prior art]
In hot seasons such as summer, clothes such as clothes having a large contact cold feeling when worn are preferred. Although various factors such as the temperature difference between clothing and skin, the degree of contact, and the surface condition of clothing are related to the cooling sensation of contact, as a general tendency, the cooling sensation of contact is closely related to the moisture retention of fibers. Relatedly, the higher the moisture retention of the fibers, the higher the cooling sensation of clothes and the like made of such fibers. This is because moisture has a high thermal conductivity, and the higher the moisture, the higher the thermal conductivity. The present invention has been developed by modifying cellulose fibers from the viewpoint of water retention and at the same time developing modified cellulose fibers having excellent contact cooling sensation characteristics.
[0003]
For example, Patent Literature 1, Patent Literature 2 or Patent Literature 3 are known as the contact cool feeling fibers.
[0004]

[Problems to be solved by the invention]
An object of the present invention is to provide a modified cellulosic fiber having excellent contact cooling sensation by means completely different from the prior art.
An object of the present invention is to provide a modified cellulosic fiber having a contact cooling sensation property by chemically modifying the surface of the cellulosic fiber to enhance the moisture retention of the fiber.
[0009]
[Means for Solving the Problems]
The present invention relates to a modified cellulose fiber in which a polyol having a molecular weight of 2000 or less is fixed by 2 to 30% by weight based on the weight of the cellulose fiber.
[0010]
The modified cellulosic fiber of the present invention has excellent moisture retention properties and, when used in clothing and the like, has excellent contact cooling sensation.
[0011]
The cellulosic fibers to which the present invention is applied are not particularly limited, and include natural celluloses such as cotton and hemp, viscose rayon, cuprammonium rayon, regenerated cellulose such as polynosic, and purified cellulose such as Tencel. Become. In addition, these cellulose-based fibers and synthetic fibers (eg, polyester, polyamide, etc.), cellulose-based fibers, or a blend of cellulose-based fibers and animal fibers (eg, wool, silk, etc.), mixed twist, interwoven, cross-knitted fabric Are also processed.
[0012]
In the present invention, a polyol having a molecular weight of 2000 or less is fixed to the above-mentioned cellulosic fiber in an amount of 2 to 30% based on the weight of the cellulosic fiber.
[0013]
Examples of the polyols that can be used in the present invention include compounds having at least two hydroxyl groups in the molecule, such as polyethylene glycol, polypropylene glycol, diethylene glycol, triethylene glycol, glycerin, erythritol, xylitol, and sorbitol. Of these compounds, polyethylene glycol is particularly preferred because of its excellent moisture retention and contact cooling sensation properties.
[0014]
The polyols used in the present invention have a molecular weight of about 2000 or less. In the present invention, the molecular weight means a weight average molecular weight. If the molecular weight is 2,000 or more, the effect of processing (modification) is small, and the obtained fiber has insufficient washing durability.
[0015]
The adhesion of the polyols to the cellulosic fibers is performed by crosslinking the cellulosic fibers and the polyols with a crosslinking agent. Glyoxal compounds such as dimethylol dihydroxyethylene urea, dimethylol propylene urea, dimethylol ethylene urea, dimethyl dihydroxy ethylene urea and modified products thereof, and epoxy compounds such as ethylene glycol diglycidyl ether, polyethylene glycol diethylene glycol Glycidyl ether, glycerol triglycidyl ether, polyglycerol polyglycidyl ether and the like can be used. Preferred are dimethylol dihydroxyethylene urea and dimethyl dihydroxyethylene urea.
[0016]
The amount of the polyol fixed to the cellulosic fiber is 2 to 30% by weight, preferably 3 to 20% by weight, based on the weight of the cellulose fiber. If the fixing amount is less than 2% by weight, the processing (modification) effect is insufficient, and if it is more than 30% by weight, the processing (modification) discoloration becomes remarkable, and the color fastness becomes poor. In the present invention, the amount of fixation is determined by the following equation.
(Absolute dry weight after processing−absolute dry weight before processing) / absolute dry weight before processing × 100 (% by weight).
[0017]
In order to fix the polyols to the cellulosic fibers, the cellulose fibers are impregnated with a solution obtained by mixing a larger amount of polyles and a crosslinking agent together with a solvent such as water and alcohol than desired to be fixed to the cellulosic fibers, and then dried. It may be cured (cured). At this time, the crosslinking agent may be added based on 0.1 to 100% by weight based on the weight of the polyols. Curing may be performed at 50 to 180 ° C. for about 10 seconds to 20 minutes.
[0018]
The above-described treatment may be performed on the cellulosic fiber in the form of a fabric, such as a woven fabric or a knitted fabric, a cotton, a thread, a nonwoven fabric, or a fiber product, in addition to the fiber form.
[0019]
The modified cellulose fibers of the present invention are excellent in moisture retention and contact coolness characteristics. Therefore, for example, clothing and the like using the modified cellulose fiber of the present invention should be clothing having a cool contact sensation, and when used as a towel, should be a towel having good moisture retention and a moist contact sensation. Can be. In addition, in a dry environment such as winter, the present invention can be applied to underwear having a moisturizing effect on the skin.
[0020]
