Abstract
Description
【0001】
【発明の属する技術分野】
本発明は、ノネナールの消臭機能に優れた繊維構造物及びその加工方法に関する。
【0002】
【従来の技術】
加齢臭の主たる原因物質であるノネナールの消臭には、金属酸化物等の無機系化合物やアミン系の低分子の有機系化合物を繊維に付着させる方法が一般的であるが、バインダーを必要とする無機系化合物では満足できる耐久性が得られず、加工面でも機械の汚れ等の問題がある。また、低分子のアミン系化合物を用いる方法では、加工初期の効果は得られるものの洗濯耐久性に乏しい欠点がある。
【0003】
一方、アルデヒドの消臭にヒドラジド化合物等を使用する従来技術があるが、皮膚への安全性に問題があり、ノネナールに対しては充分な効果が得られていない。
【0004】
また、親水性ビニル系モノマーをグラフト重合させたものに、光触媒機能を有する金属酸化物を付与する方法があるが、これも洗濯耐久性が得られていない(特開2001−172868号公報)。更に、繊維に光触媒剤とアルキルシリコーン樹脂、シリコーン系樹脂及びフッ素系樹脂から選ばれたバインダーを組み合せる方法があるが、これも洗濯耐久性に優れるものは得られていない(特開2001−238777号公報)。
【0005】
また、繊維にアセタール結合、エーテル結合等でフラボノイド類を結合させたものに、無機金属酸化物を付与する方法もあるが(特開2002−4172号公報、特開2001−234470号公報)、いずれも十分な結果が得られておらず、改善が必要とされている。

【0009】
即ち、本発明は、繊維構造物に対してポリカチオンを付着させてなることを特徴とする消臭性繊維構造物、及び繊維構造物を漂白し、液体アンモニア処理を行った後にテンターを用いたパッド/ドライ法により繊維構造物にポリカチオンを付着させる消臭性繊維構造物の加工方法を提供する。
【0010】
以下、本発明につき更に詳しく説明する。
本発明で用いる繊維構造物の繊維形態としては、糸、綿、織編物、不織布等が挙げられる。これらの繊維素材としては、木綿、麻、羊毛等の天然繊維、レーヨン、ポリノジック、キュプラ、高強度再生セルロース繊維(例えば、商品名テンセル)等の再生繊維、アセテート等の半合成繊維、ポリエステル、ナイロン等の合成繊維、及びこれらの繊維を2種以上組み合せた混紡、交織繊維等が使用される。これらの中で、本発明においては、綿繊維を20重量%以上、特に35重量%以上用いた繊維構造物が好適に用いられる。
【0011】
本発明においては、上記繊維構造物にポリカチオンを付着させることで、特にノネナールに対する高い消臭性能を有する繊維構造物を得るものである。
【0012】
ここで、本発明で使用されるポリカチオンとしては、アリルアミン系重合物、ジアリルアミン系重合物などが挙げられ、例えばジメチルアミン・エピクロルヒドリン重合物、ジメチルジアリルアンモニウムクロライド重合物、モノアリルアミン塩酸塩重合物、ジアリルアミン塩酸塩重合物、ジメチルジアリルアンモニウムクロライド重合物、ジアルキルアミノエチル(メタ)アクリレート4級化物の重合物、ジアリルアミン塩・二酸化硫黄共重合物、ジメチルジアリルアンモニウムクロライド・二酸化硫黄共重合物、モノアリルアミン塩酸塩・ジメチルジアリルアンモニウムクロライド共重合物等が挙げられる。

本発明の消臭性繊維構造物の消臭機構は、ポリカチオンのアミノ基がノネナール(CH3(CH2)6CH=CHO)のアルデヒド基とシッフ反応することにより消臭効果が得られるものである。ポリカチオンは特に綿繊維との親和性に優れ、高分子であるため洗濯により脱落し難いと考えられる。
【0024】
本発明の消臭性繊維構造物の加工方法では、上述したポリカチオンを単独で、又は通常使用されている消臭剤、バインダー及び光触媒等と併せて使用することができる。これにより、ノネナールに対する消臭効果がより高まると共に、ノネナール等のアルデヒド臭気以外にも、アンモニア等の塩基性化合物や、酢酸、イソ吉草酸といった低級脂肪酸等の臭気成分に対しても優れた消臭効果を得ることができる。
【0025】
本発明で用いられる消臭剤は、ZnO、TiO2、TiO2−SiO2複合酸化物、リン酸ジルコニウム、リン酸チタニア系化合物、金属錯体、フラボン誘導体、ゼオライト等を含有するものが挙げられる。

【0027】
本発明で使用するバインダーとしては、アクリル樹脂、メタクリル樹脂、ウレタン樹脂、シリコーン樹脂、酢酸ビニル樹脂、アクリル−シリコーン共重合樹脂、ポリエステル樹脂、グリオキザール樹脂等が挙げられる。
【0028】
上記バインダーの使用量は、繊維構造物に対する付着量が、好ましくは0.1〜10重量%、より好ましくは0.5〜8重量%、特に好ましくは1〜5重量%となるように使用する。
また、本願発明では光触媒を使用することで、ノネナールの消臭効果をより高めることができる。光触媒は紫外線の照射により消臭機能を発揮する触媒であるが、このような光触媒機能をもつ化合物としては、酸化チタン等が挙げられる。
【0029】
上記光触媒の使用量は、繊維構造物に対する付着量が、0.01〜10重量%、好ましくは0.1〜8重量%、特に好ましくは0.5〜5重量%となるように使用する。
【0030】
本発明の繊維構造物の加工方法では、ポリカチオンを含有する処理液を繊維構造物へ付着させる方法として、テンターを用いたパッド/ドライ法、液流染色機、ドラム染色機等を用いた浸漬法が採用されるが、特に本発明では、作業性やコストの面でパッド/ドライ法が好ましく用いられる。この場合、繊維構造物を液体アンモニア処理した後に、ポリカチオンを含有する処理液を付着させるのが好ましい。
【0031】

BACKGROUND OF THE INVENTION
The present invention relates to a fiber structure excellent in the deodorizing function of Nonenal and a processing method thereof.
[0002]
[Prior art]
To deodorize Nonenal, which is the main cause of aging odor, it is common to attach inorganic compounds such as metal oxides or amine-based low molecular weight organic compounds to the fiber, but a binder is required. However, satisfactory durability cannot be obtained with the inorganic compound, and there are problems such as machine stains on the processed surface. In addition, the method using a low molecular weight amine compound has the disadvantage that the washing durability is poor although an effect at the initial stage of processing can be obtained.
[0003]
On the other hand, there is a conventional technique that uses a hydrazide compound or the like for deodorizing aldehydes, but there is a problem with safety to the skin, and a sufficient effect is not obtained for Nonenal.
[0004]
In addition, there is a method of imparting a metal oxide having a photocatalytic function to a graft polymer of a hydrophilic vinyl monomer, but this also has no washing durability (Japanese Patent Laid-Open No. 2001-172868). Furthermore, there is a method in which a fiber is combined with a binder selected from a photocatalyst agent and an alkyl silicone resin, a silicone resin, and a fluorine resin. However, this method is not excellent in washing durability (Japanese Patent Laid-Open No. 2001-238777). Issue gazette).
[0005]
In addition, there is a method in which an inorganic metal oxide is added to a fiber in which a flavonoid is bonded by an acetal bond, an ether bond, or the like (JP 2002-4172 A, JP 2001-234470 A). However, sufficient results have not been obtained and improvements are needed.

[0008]
Means for Solving the Problem and Embodiment of the Invention
As a result of intensive studies to achieve the above-mentioned object, the present inventor has obtained a fiber structure excellent in washing durability and effective in deodorizing Nonenal by attaching a polycation to the fiber structure. As a result, the present invention has been made.
[0009]
That is, the present invention uses a tenter after bleaching a fiber structure and carrying out liquid ammonia treatment, which is characterized in that a polycation is adhered to the fiber structure. Provided is a method for processing a deodorant fiber structure in which a polycation is adhered to a fiber structure by a pad / dry method.

Among these, in the present invention, a fiber structure using 20% by weight or more, particularly 35% by weight or more of cotton fiber is preferably used.
[0011]
In the present invention, by attaching a polycation to the above fiber structure, a fiber structure having particularly high deodorizing performance against Nonenal is obtained.
[0012]
Here, examples of the polycation used in the present invention include allylamine polymers, diallylamine polymers, and the like, such as dimethylamine / epichlorohydrin polymer, dimethyldiallylammonium chloride polymer, monoallylamine hydrochloride polymer, Diallylamine hydrochloride polymer, dimethyldiallylammonium chloride polymer, dialkylaminoethyl (meth) acrylate quaternized polymer, diallylamine salt / sulfur dioxide copolymer, dimethyldiallylammonium chloride / sulfur dioxide copolymer, monoallylamine hydrochloride And salt / dimethyldiallylammonium chloride copolymer.

The polycation is used in such an amount that the amount attached to the fiber structure is 0.1 to 10% by weight, more preferably 0.1 to 5% by weight, and particularly preferably 0.5 to 3% by weight.
[0023]
The deodorization mechanism of the deodorant fiber structure of the present invention is such that the deodorizing effect is obtained by the Schiff reaction of the amino group of the polycation with the aldehyde group of nonenal (CH 3 (CH 2 ) 6 CH═CHO). It is. Polycation is particularly excellent in affinity with cotton fiber, and is a polymer, so it is considered difficult to drop off by washing.
[0024]
In the processing method of the deodorant fiber structure of this invention, the polycation mentioned above can be used individually or in combination with the deodorant, binder, photocatalyst, etc. which are normally used. As a result, the deodorizing effect on Nonenal is further enhanced, and in addition to aldehyde odors such as Nonenal, it is also excellent for odorous components such as basic compounds such as ammonia and lower fatty acids such as acetic acid and isovaleric acid. An effect can be obtained.
[0025]
Examples of the deodorant used in the present invention include those containing ZnO, TiO 2 , TiO 2 —SiO 2 composite oxide, zirconium phosphate, phosphoric titania compound, metal complex, flavone derivative, zeolite and the like.

Moreover, in this invention, the deodorizing effect of nonenal can be improved more by using a photocatalyst.

[0029]
The photocatalyst is used in such an amount that the amount attached to the fiber structure is 0.01 to 10% by weight, preferably 0.1 to 8% by weight, particularly preferably 0.5 to 5% by weight.
[0030]
In the fiber structure processing method of the present invention, a pad / dry method using a tenter, a liquid dyeing machine, a drum dyeing machine or the like is used as a method for attaching a treatment liquid containing polycations to the fiber structure. In particular, in the present invention, the pad / dry method is preferably used in terms of workability and cost. In this case, it is preferable to attach a treatment liquid containing a polycation after the fiber structure is treated with liquid ammonia.
