Description
本発明は、シルク(繭、絹糸)から精製した加水分解セリシンやセリシンパウダーによるセリシンを弱い力で洗濯後の繊維に付与でき、そのためこのセリシンをこの繊維に触れる肌に徐々に付与させることができ、そのためたとえば繊維の肌触りの向上のみならず、その繊維に触れる肌に保湿効果や防臭効果などを付与することができる機能をも有する新機能柔軟剤に関するものである。 In the present invention, hydrolyzed sericin purified from silk (cocoon, silk thread) or sericin powder can be imparted to fibers after washing with a weak force, so that sericin can be gradually imparted to the skin in contact with the fibers. Therefore, the present invention relates to a new functional softening agent that not only improves the texture of fibers, but also has the function of imparting a moisturizing effect and a deodorant effect to the skin in contact with the fibers.
シルクは、美しさ、肌触りの良さだけでなく、通気性や透湿性などに優れているため、古くから高級素材として衣料分野に利用されてきているが、近年シルクの主成分であるセリシンやフィブロインが数種類のアミノ酸で構成されているタンパク質であることから、たとえばその特性や機能性を活かして繊維に付与したり、化粧品、食品、その他非衣料分野での利活用も増えてきている。 Silk has been used in the field of clothing for a long time as a luxury material because it is not only beautiful and pleasant to the touch, but also has excellent breathability and moisture permeability. Since is a protein composed of several types of amino acids, its characteristics and functionality are being applied to fibers, and its utilization in cosmetics, foods, and other non-clothing fields is increasing.
たとえば、セリシンには、保湿効果、抗酸化作用による防臭効果などが知られているが、このような機能が期待できるセリシンを繊維に付与するため、カチオン系表面処理を繊維に施し、さらにセリシンによるタンパク質層を表面に形成した機能性繊維製品の研究開発なども進められてきている。(特許文献１) For example, sericin is known for its moisturizing effect and deodorizing effect due to its antioxidant action. Research and development of functional fiber products with a protein layer formed on the surface have also been advanced. (Patent Document 1)
しかしながら、繊維製品にこのような表面処理を行いさらにセリシンタンパク質層を形成することは容易ではなく、そのためコスト高となって価格が高くなってしまう問題や商品バリエーションが少なくならざるを得なく客層を拡大することができないなどの問題があった。 However, it is not easy to apply such a surface treatment to textile products and form a sericin protein layer. There were problems such as not being able to expand.
また一方、前述のようにして工場で繊維製品にセリシンを付与させる場合、強固な結合力(強固な吸着力や強固な結合力)で繊維に付与してしまうことになるため、数回の洗濯にも耐え容易にこのセリシンが離脱することはないが、逆にそのためにセリシンにより繊維自体の機能が改善できても、繊維をまとう肌への機能効果は期待できない。 On the other hand, when sericin is applied to textile products at a factory as described above, it is applied to the fiber with a strong binding force (strong adsorption force or strong binding force), so it is necessary to wash it several times. This sericin is not easily removed from the skin even if the sericin is able to withstand the stress, but conversely, even if the function of the fiber itself can be improved by sericin, no functional effect on the skin covered with the fiber can be expected.
逆に弱い結合力で繊維に付与するとなれば、数回の洗濯でセリシンは落ちてしまい単発的な機能性繊維製品となってしまい、費用対効果はさらに劣り商品価値をさらに落としてしまうこととなる。そのため実用性に乏しくなかなか普及し得ないのが現状であった。 Conversely, if a weak binding force is applied to the fiber, the sericin will be removed after several washes, resulting in a one-shot functional fiber product, which will further reduce the cost-effectiveness and further reduce the product value. Become. For this reason, the present situation is that it lacks practicality and cannot be widely used.
本発明は、このような問題を解決するもので、洗濯後に繊維に柔軟性を付与するための柔軟剤(仕上げ剤)に着眼し、工場で繊維製品に強固にセリシンを付与するのでなく、たとえば単に洗濯後のすすぎ時に入れることで容易に洗濯済みの繊維に柔軟性のみならずセリシンを付与することができ、しかもカチオン系キトサン誘導体などのカチオン性高分子と溶液中セリシンとが静電吸着または静電付着し(いわば軽いイオン結合で結び付き)これが繊維に静電吸着または静電付着する(いわば軽いイオン結合により付着する)ことで、繊維に軽い結合力でセリシンを付与することができる構成のため、セリシンと繊維との結合(吸着)は弱く数回の洗濯に耐える程度の耐久性(機能維持性)を有しつつも適度に肌へ徐々にセリシンが離脱することで肌にセリシンを付与することができ、そのため肌へたとえば保湿効果、防臭効果などのセリシン機能を容易に付与することができ、数回の洗濯ごとに適量注ぐだけで繰り返しこのセリシン機能を繊維を介して肌に付与することができ、費用対効果も優れるなど極めて実用性に優れた画期的な柔軟剤を提供することを目的としている。 The present invention solves such problems, focusing on a softening agent (finishing agent) for imparting flexibility to textiles after washing. By simply putting it in the rinse after washing, it is possible to easily impart not only flexibility but also sericin to the washed fibers. It is electrostatically attached (bonded by a light ionic bond, so to speak), which is electrostatically adsorbed to the fiber or electrostatically adhered (attached by a light ionic bond, so to speak), so that sericin can be imparted to the fiber with a light binding force. Therefore, the bond (adsorption) between sericin and fibers is weak, and while it has durability (function maintenance) that can withstand several washings, sericin is gradually released from the skin to give sericin to the skin. Therefore, sericin function such as moisturizing effect and deodorizing effect can be easily imparted to the skin, and the sericin function can be repeatedly imparted to the skin through the fibers by simply pouring an appropriate amount for each washing several times. It is an object of the present invention to provide an epoch-making softening agent which is extremely practical such as being able to soften and having excellent cost-effectiveness.

本発明は上述のように構成したから、たとえば単に洗濯後のすすぎ時に入れることで容易に洗濯済みの繊維に柔軟性のみならずセリシンを付与することができ、しかもカチオン系キトサン誘導体などのカチオン性高分子と溶液中セリシンとが静電吸着または静電付着し(いわば軽いイオン結合で結び付き)これが繊維に静電吸着または静電付着する(いわば軽いイオン結合により付着する)ことで、繊維に軽い結合力でセリシンを付与することができる構成のため、セリシンと繊維との結合(吸着)は弱く数回の洗濯に耐える程度の耐久性(機能維持性)を有しつつも適度に肌へ徐々にセリシンが離脱することで肌にセリシンを付与することができ、そのため肌へたとえば保湿効果、防臭効果などのセリシン機能を容易に付与することができ、数回の洗濯ごとに適量注ぐだけで繰り返しこのセリシン機能を繊維を介して肌に付与することができ、費用対効果も優れるなど極めて実用性に優れた画期的な柔軟剤となる。 Since the present invention is constructed as described above, it is possible to easily impart not only flexibility but also sericin to washed fibers simply by putting them in, for example, when rinsing after washing. Polymers and sericin in solution are electrostatically adsorbed or adhered (bonded by light ionic bonds, so to speak). Because of the structure that can impart sericin with binding force, the binding (adsorption) between sericin and fibers is weak, and while it has durability (function maintenance) that can withstand several washings, it gradually adheres to the skin. Sericin can be imparted to the skin by removing sericin from the skin, so sericin functions such as moisturizing effect and deodorant effect can be easily imparted to the skin, and can be repeated by simply pouring an appropriate amount every several times of washing. The sericin function can be imparted to the skin through the fibers, making it an epoch-making softening agent with excellent practicality, such as excellent cost-effectiveness.
本発明の最適な実施形態を図面に基づいて本発明の作用を示し簡単に説明する。 Optimal embodiments of the present invention will be briefly described with reference to the drawings showing the operation of the present invention.
シルクたとえば繭から精製した加水分解セリシンと、このセリシンが静電吸着または静電付着する(いわば弱いイオン結合により付着する)カチオン性高分子(たとえばこの弱い力で加水分解セリシンと結合することになるカチオン系キトサン誘導体)とが含まれている構成とした本発明品の柔軟剤を、洗濯後の水を含んでいる繊維(洗濯する繊維製品)に付与する。たとえば洗濯後のすすぎ時にこの洗濯槽に適量注ぎ入れると、前記加水分解セリシンと結合している前記カチオン性高分子(たとえばカチオン系キトサン誘導体)が繊維に静電吸着または静電付着する(いわば弱いイオン結合により付着する)ことにより、このカチオン性高分子を介してこの繊維に前記セリシンが弱い結合力で付与される。 Hydrolyzed sericin purified from silk, for example, cocoons, and cationic macromolecules to which sericin is electrostatically adsorbed or electrostatically adhered (so to speak, adhered by weak ionic bonds) (for example, this weak force binds to hydrolyzed sericin). A cationic chitosan derivative) of the present invention is applied to fibers containing water after washing (textile products to be washed). For example, when an appropriate amount is poured into the washing tub during rinsing after washing, the cationic polymer (for example, a cationic chitosan derivative) bound to the hydrolyzed sericin is electrostatically adsorbed or electrostatically attached (so to speak, weakly) to the fibers. ionic bond), the sericin is imparted to the fiber through the cationic polymer with a weak binding force.
このセリシンは、このように弱い力で前記カチオン性高分子と結びつき、このカチオン性高分子も弱い力で繊維と結びついているため、このセリシンが付与された繊維が肌と接触することで、この繊維からセリシンは徐々に離脱して肌に付与されることとなる。 The sericin is weakly bound to the cationic polymer, and the cationic polymer is also weakly bound to the fiber. Sericin is gradually released from the fibers and applied to the skin.
すなわち、負に帯電あるいは負の極性を有する前記セリシンが、前記正に帯電しているあるいは正の極性を有する前記カチオン性高分子を介して表面が負に帯電しているあるいは負の極性を有する前記繊維に容易に付与できることとなる。 That is, the surface of the negatively charged or negatively charged sericin or the negatively charged cationic polymer is interposed between the positively charged or positively charged cationic polymer, or has a negatively charged surface. It can be easily applied to the fibers.
しかもこのセリシンは、前述のように前記繊維および前記カチオン性高分子との結びつきが弱いため(弱い力、いわば弱いイオン結合で結びついて付着しているため)、数回の洗濯で落ちてしまうがこの間繊維と肌とが接触することで、この繊維から徐々に離脱し肌にセリシンを付与できることとなる。 Moreover, since this sericin is weakly bound to the fiber and the cationic polymer as described above (because it is bound and adhered by a weak force, so to speak, weak ionic bond), it is washed off several times. During this time, the fibers come into contact with the skin, so that sericin is gradually released from the fibers and sericin can be imparted to the skin.
そのため、肌へたとえば保湿効果、防臭効果などを与えるセリシン機能を、繊維と接触する肌に容易に付与することができることとなる。 As a result, the sericin function that imparts, for example, a moisturizing effect and a deodorizing effect to the skin can be easily imparted to the skin that comes into contact with the fibers.
したがって、たとえば数回の洗濯ごとに適量注ぐだけで、繊維の柔軟性を繰り返し高めることができるあるいは肌触りを向上できるだけでなく、繰り返しこのセリシン機能(新機能)を繊維を介して肌に付与することができ、費用対効果も極めて優れる柔軟剤となるものである。 Therefore, for example, just by pouring an appropriate amount every several times of washing, it is possible not only to repeatedly increase the flexibility of the fibers or improve the touch, but also to repeatedly impart this sericin function (new function) to the skin through the fibers. It can be used as a softening agent that is extremely cost-effective.
本発明の具体的な実施例１について図面に基づいて説明する。 A specific embodiment 1 of the present invention will be described with reference to the drawings.
本実施例では、加水分解セリシンと、このセリシンが静電吸着または静電付着するカチオン性高分子とを含む構成としている。 In this embodiment, the structure includes hydrolyzed sericin and a cationic polymer to which sericin is electrostatically adsorbed or adhered electrostatically.
具体的には、たとえば下着や靴下、タオルなどの肌に触れるあるいは肌に直接まとう繊維製品に、水1000に対して本発明品の柔軟剤１程度の割合で水に希釈させて繊維に付与してセリシンを付与させるもので、たとえばこのような繊維製品を家庭の洗濯時や洗濯業者による洗濯時の洗濯後(たとえば洗濯後のすすぎ時の洗濯槽内)に本発明品(柔軟剤)を適量注ぎ入れると、負に帯電しているあるいは負の極性を有する前記加水分解セリシンが、正に帯電しているもしくは正の極性を有する前記カチオン性高分子を介して、表面が負に帯電しているもしくは負の極性を有する前記繊維に付与される構成としている。 Specifically, for example, it is diluted with water at a ratio of about 1 part of the softener of the present invention to 1000 parts of water and applied to textile products such as underwear, socks, and towels that come into contact with the skin or are worn directly on the skin. For example, after washing such textile products at home or by a laundry company (for example, in the washing tub when rinsing after washing), an appropriate amount of the product (softener) of the present invention is added. When poured, the hydrolyzed sericin, which is negatively charged or has a negative polarity, becomes negatively charged on the surface via the cationic polymer, which is positively charged or has a positive polarity. or is imparted to the fibers having a negative polarity.
すなわち、前記加水分解セリシンとコンプレックスを作り結合している前記カチオン性高分子が繊維に静電吸着または静電付着する(いわば弱いイオン結合により付着する)ことにより、このカチオン性高分子を介してこの繊維に前記セリシンが弱い結合力で付与される構成としている。 That is, the cationic polymer that forms a complex with the hydrolyzed sericin and is bound to the fiber is electrostatically adsorbed or electrostatically adhered to the fiber (so to speak, adhered by a weak ionic bond). The fiber is configured such that the sericin is imparted with a weak binding force.
したがって、このセリシンは、このように弱い力で前記カチオン性高分子と結びつき、このカチオン性高分子も弱い力で繊維と結びついているため、このセリシンが付与された繊維が肌と接触することでこの繊維からセリシンが徐々に離脱して肌に付与される(少しずつセリシンが肌へ刷り込まれていく)こととなる構成としている。 Therefore, the sericin is weakly bound to the cationic polymer, and the cationic polymer is also weakly bound to the fiber. The structure is such that sericin is gradually released from the fibers and imparted to the skin (sericin is gradually imprinted into the skin).
また、本実施例では、繊維表面にこのように加水分解セリシンとカチオン性高分子が付与されることで表面の摩擦抵抗が少なくなり柔軟性を帯び柔軟効果が発揮されるが、この繊維の柔軟効果を増強するため、さらにカチオン性油性分を加えている。また一般の柔軟剤のようにカチオン系界面活性剤を加えてもよい。 Moreover, in this example, by adding hydrolyzed sericin and a cationic polymer to the surface of the fiber in this way, the frictional resistance of the surface is reduced and the surface becomes soft and the softening effect is exhibited. A cationic oil component is added to enhance the effect. A cationic surfactant may also be added like a general softening agent.
また本実施例では、前述のように前記繊維と肌が接触することでセリシンが徐々に離脱してセリシンが少しずつ肌へ刷り込まれていく程度の弱い結合力で、あるいはたとえば数回の洗濯により前記繊維からセリシンがほぼ完全に離脱してしまう程度の弱い結合力で(静電吸着または静電付着で)前記カチオン性高分子を介して前記繊維に付与される構成としている。 Further, in the present embodiment, as described above, sericin is gradually removed by contacting the fibers with the skin, and sericin is gradually imprinted on the skin with a weak binding force, or after washing several times, for example. The sericin is imparted to the fibers through the cationic polymer with such a weak binding force (by electrostatic adsorption or electrostatic adhesion) that sericin is almost completely detached from the fibers.
具体的には毎回の洗濯時ではなく３回に１回くらいの割合で洗濯時に通常の柔軟剤と同じようにして、自動洗濯機の柔軟剤を自動注入させるための柔軟剤収容ボックスに適量収納してすすぎ時の洗濯槽に自動投入させる柔軟剤であり、前記弱い結合力による付着のため数回の洗濯で落ちてしまうがそれまでの間この繊維製品を着ていることで(この繊維と肌とが接触することで)、この繊維から徐々にセリシンが離脱し肌にセリシンが徐々に付与されるように構成し、たとえば肌のうるおいを保つ保湿効果、抗酸化作用により黄色ブドウ球菌の繁殖を抑え汗の匂いを出さず汗疹を抑え肌を清潔に保つ防臭効果などを与えるセリシン機能を、繊維と接触する肌に付与することができる新機能を発揮する柔軟剤に構成している。 Specifically, it is stored in a softener storage box for automatic injection of softener in an automatic washing machine in the same way as normal softener when washing about once every three times instead of every wash. It is a softening agent that is automatically put into the washing tub when rinsing, and it will fall off after several washes due to the weak bonding force described above, but until then, wearing this textile product (with this fiber When it comes into contact with the skin), sericin is gradually removed from these fibers and sericin is gradually given to the skin, for example, it has a moisturizing effect that keeps the skin moist and an antioxidant effect, which causes the growth of Staphylococcus aureus. It is composed of a softening agent that exerts a new function that can give sericin function, which suppresses sweat odor, suppresses eczema, keeps skin clean, and deodorizes the skin that comes into contact with the fabric.
したがって、たとえば数回の洗濯ごとに適量注ぐだけで、繊維の柔軟性を繰り返し高めることができる(肌触りを向上させることができる)だけでなく、繰り返しこのセリシン機能(新機能)を、繊維を介して肌に付与することができる柔軟剤となる。 Therefore, for example, by simply pouring an appropriate amount every few times of washing, it is possible not only to repeatedly increase the flexibility of the fibers (improve the feel of the skin), but also to repeat the sericin function (new function) through the fibers. It becomes a softening agent that can be applied to the skin.
また本実施例では、このような画期的な作用効果、すなわち簡易な手法で(たとえば各家庭で洗濯時に用いるだけで)繊維に付与でき、且つあえて適度に弱い結合力で繊維に付与させることで適度に(少しずつ徐々に)離脱させて肌にセリシンを持続的に付与して、このセリシンによる保湿効果や抗酸化作用による防臭効果などの機能を肌に与えることができる画期的な新機能柔軟剤を実現できる(弱い結合でのセリシン付与を実現できる)ものである。 In addition, in this embodiment, such an epoch-making action and effect, that is, it can be imparted to fibers by a simple method (for example, by simply using it at home when washing), and it can be imparted to fibers with a moderately weak binding force. Sericin is given to the skin continuously by moderately (gradually) detaching from sericin, and this epoch-making new product can provide the skin with functions such as moisturizing effect by sericin and deodorant effect by antioxidant action. It can realize a functional softening agent (can realize application of sericin with a weak bond).
本実施例は、このような柔軟剤を実現できる前記カチオン性高分子を見出したものであるが、さらに実験を繰り返すことで、この作用効果を果たすものとしてカチオン性高分子のなかで、被覆系製で保湿効果、柔軟効果などに優れ、加水分解セリシンとコンプレックスを作り前述した弱い結合力で繊維にセリシンを付着させることに優れたカチオン系キトサン誘導体を見出し、これと加水分解セリシンとをダブル配合する構成としている。 In this example, the cationic polymer that can realize such a softening agent was discovered. By repeating the experiment, it was found that among the cationic polymers that achieve this effect, the coating system We found a cationic chitosan derivative that is excellent in moisturizing and softening effects, and that forms a complex with hydrolyzed sericin and attaches sericin to fibers with the aforementioned weak binding force. It is configured to
すなわち、天然保湿素材である加水分解セリシンとカチオン系キトサン誘導体とのダブル配合により実現したもので、衣類をしっとり柔らかくシルクタッチの風合いに近づける(肌への摩擦を軽減し滑らかな肌触りに仕上げる)ととともに、着ながらにして徐々にセリシンを肌に刷り込ませて肌の保湿効果や防臭効果などのセリシン機能を付与できるように構成したものである。単にセリシンを付与したのでは１回の洗濯程度ですぐに落ちてしまうが、カチオン系キトサン誘導体とのダブル配合で適度に繊維からセリシンが落ちて着ているだけでセリシンが肌へ少しずつ刷り込まれて、保湿効果、抗菌防臭効果を肌に与えることができる新機能性柔軟剤を実現したものである。(たとえばこの本発明品の柔軟剤を使用後、この柔軟剤なしで数回洗濯しても前記作用効果が持続し、再度柔軟剤を使用すればまたこの作用効果を繰り返し継続させることができるものである。) In other words, the combination of hydrolyzed sericin, which is a natural moisturizing material, and a cationic chitosan derivative has been combined to create a moist, soft, silky texture (reduce friction on the skin and create a smooth texture). In addition, sericin is gradually imprinted into the skin while being worn, so that sericin functions such as moisturizing effect and deodorant effect can be imparted to the skin. If sericin is simply added, it will come off after just one wash, but with the double formulation with the cationic chitosan derivative, the sericin will be moderately removed from the fibers and will be imprinted on the skin little by little just by wearing it. As a result, a new functional softening agent that can impart a moisturizing effect and an antibacterial and deodorant effect to the skin has been realized. (For example, after using the softener of the present invention, the action and effect can be maintained even after washing several times without the softener, and the action and effect can be continued repeatedly by using the softener again. is.)
さらに具体的に説明すると、本実施例では、繭を水に入れて圧力釜で高温高圧加熱して抽出した液体状の加水分解セリシン(これを乾燥させたセリシンパウダーを溶かしたものでもよい)を、1～３０％、カチオン系キトサン誘導体(たとえばキトサンイソステアラミドヒドロキシプロピルトリモニウムクロイド)を0.1～5.0％含んだ構成とし、さらに柔軟性を高める前記カチオン性油性分やカチオン系界面活性剤、さらに抗菌性を高める茶カテキン、さらに保湿性を高めるグリセリンやグリコール、さらにセリシンと同様に繭や絹糸から精製され肌に徐々に刷り込まれて肌に肌修復効果を付与するフィブロイン(加水分解フィブロイン)を含んだ構成としている。 More specifically, in the present example, liquid hydrolyzed sericin extracted by placing cocoons in water and heating at high temperature and high pressure in a pressure cooker (or by dissolving dried sericin powder) was added. , 1 to 30%, and 0.1 to 5.0% of a cationic chitosan derivative (e.g., chitosan isostearamide hydroxypropyltrimonium chloride). It contains tea catechin that enhances antibacterial properties, glycerin and glycol that enhances moisturizing properties, and fibroin (hydrolyzed fibroin), which is purified from cocoons and silk threads like sericin and is gradually imprinted on the skin to give the skin a repair effect. It is configured.
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 It should be noted that the present invention is not limited to this embodiment, and the specific configuration of each component can be appropriately designed.
また負に帯電しているあるいは負の極性を有する前記セリシンが、洗濯後の水を含んでいる前記繊維に正に帯電しているもしくは正の極性を有する前記カチオン性高分子を介して、表面が負に帯電しているもしくは負の極性を有する前記繊維に付与されるように構成されていて、このセリシンは、前記繊維と肌とが接触することおよび数回の家庭での洗濯により前記繊維から離脱する程度の弱い静電吸着または静電付着で前記カチオン性高分子を介して前記繊維に付与されるように構成されていることを特徴とする請求項１記載の柔軟剤に係るものである。
In addition, the negatively charged or negatively charged sericin is transferred to the fiber containing water after washing via the positively charged or positively charged cationic polymer on the surface. is imparted to the fibers that are negatively charged or have a negative polarity, and the sericin is transferred to the fibers by contacting the fibers with the skin and by washing several times at home. 2. The softener according to claim 1, wherein the softener is applied to the fiber through the cationic polymer by weak electrostatic adsorption or electrostatic adhesion to the extent that it is separated from the be.
本発明の最適な実施形態を本発明の作用を示し簡単に説明する。
