Description
本発明は、セルロース系繊維を構成繊維とする不織布に関するものである。 The present invention relates to a nonwoven fabric composed of cellulosic fibers.
セルロース系繊維においては、中でも代表的な繊維として、天然繊維である木綿繊維が挙げられる。木綿繊維を構成繊維とする不織布は、吸水性を有し、また、天然繊維であることから肌に優しいため、肌に直接触れる用途、例えば、パンティライナー等の衛生用品、お尻拭きやおしぼり等のウェットシート、美容液やクレンジング液等の化粧料を含浸させた化粧料シート等の材料シートとして好適に用いられている。特に、上記した用途には、木綿繊維を構成繊維とし、構成繊維相互間が高圧水流の作用によって交絡させた不織布が用いられており、繊維相互間が交絡によってのみ不織布形態を保持しているため、敏感な肌に対しても好適に使用されている。このような木綿繊維からなる交絡不織布は、構成繊維同士が緊密に交絡していることから、また、木綿繊維特有の性質から、コシがあり、しっかりとした感触のものである。 Among cellulosic fibers, cotton fibers that are natural fibers can be cited as typical fibers. Non-woven fabric composed of cotton fibers has water absorption and is gentle to the skin because it is a natural fiber, so it can be used directly on the skin, such as sanitary products such as panty liners, wipes on the hips, and towels. It is suitably used as a material sheet such as a cosmetic sheet impregnated with a cosmetic material such as a wet sheet, a cosmetic liquid or a cleansing liquid. In particular, for the above-mentioned uses, a nonwoven fabric in which cotton fibers are used as constituent fibers and the constituent fibers are entangled by the action of high-pressure water flow is used, and the nonwoven fabric form is maintained only between the fibers by entanglement. It is also preferably used for sensitive skin. Such an entangled nonwoven fabric made of cotton fibers has a firm and firm feel because the constituent fibers are closely entangled with each other and because of the unique properties of cotton fibers.
木綿繊維が用いられた交絡不織布において、用途に応じた機能性を付加した不織布として、伸長性および伸縮性を有する不織布を本件出願人は提案している（特許文献１）。 The present applicant has proposed a non-woven fabric having extensibility and stretchability as a non-woven fabric to which functionality according to the application is added in the entangled non-woven fabric using cotton fibers (Patent Document 1).
本発明は、木綿繊維に代表されるセルロース系繊維からなる不織布において、さらに機能性を付加した不織布を提供することを課題とする。 This invention makes it a subject to provide the nonwoven fabric which added the functionality further in the nonwoven fabric which consists of a cellulose fiber represented by the cotton fiber.
本発明者は、木綿繊維が用いられた交絡不織布において、従来にない機能性を付加すべく、種々検討していたところ、木綿繊維を用いていながら、コシがなく、ドレープ性を付与することを見出し、本発明に到達した。 The present inventor has been variously studied to add unprecedented functionality in the entangled nonwoven fabric using cotton fibers, and while using the cotton fibers, there is no stiffness and imparts drapeability. The headline, the present invention has been reached.
本発明は、セルロース系繊維によって構成される不織布であり、構成繊維同士は三次元的に交絡してなり、前記不織布にはステアリン酸アミドが不織布に対して０．０２５〜０．２質量％の範囲で付着されていることを特徴とする不織布を要旨とするものである。 The present invention is a nonwoven fabric composed of cellulosic fibers, constituting fibers becomes entangled three-dimensionally, said non-woven fabric of 0.025 to 0.2 wt% stearamide respect nonwoven The gist of the nonwoven fabric is that it is adhered in a range .
モノグリセリドは一般に食品や化粧品において乳化剤として使用されており、カルボン酸アミドは例えば離型剤として知られている。本発明では、これらを、セルロース系繊維を構成繊維とする交絡不織布に適用することで、その理由は明らかではないが、該不織布に優れた柔軟性とドレープ性を付与することを可能としたものである。 Monoglycerides are generally used as emulsifiers in foods and cosmetics, and carboxylic acid amides are known as release agents, for example. In the present invention, these are applied to an entangled nonwoven fabric comprising cellulosic fibers as constituent fibers, but the reason is not clear, but the nonwoven fabric can be provided with excellent flexibility and draping properties. It is.
以下、本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail.
本発明の不織布は、セルロース系繊維によって構成される。セルロース系繊維としては、木綿繊維、レーヨン繊維、リヨセル繊維等の従来公知のものが挙げられるが、本発明では、木綿繊維を用いることによって、本発明の効果をより効果的に奏することができる。さらに、本発明では、木綿繊維のみによって不織布を構成することにより、不織布にドレープ性を付与するという効果を最も効果的に奏することができる。 The nonwoven fabric of the present invention is composed of cellulosic fibers. Examples of the cellulosic fibers include conventionally known fibers such as cotton fibers, rayon fibers, and lyocell fibers. In the present invention, the effects of the present invention can be more effectively achieved by using cotton fibers. Furthermore, in this invention, the effect of providing a drape property to a nonwoven fabric can be most effectively show | played by comprising a nonwoven fabric only with a cotton fiber.
セルロース系繊維の繊度や繊維長は、一般的に使用されている範囲のものを用いればよく、具体的には、１〜１０デシテックスで１０〜１００ｍｍ程度である。レーヨン繊維やリヨセル繊維としては、連続繊維を用いてもよいが、構成繊維同士の交絡性の観点から特定の繊維長を有する短繊維を用いることが好ましい。 The fineness and the fiber length of the cellulosic fiber may be in the range generally used, and specifically, about 10 to 100 mm with 1 to 10 dtex. As the rayon fiber or lyocell fiber, continuous fibers may be used, but short fibers having a specific fiber length are preferably used from the viewpoint of entanglement between the constituent fibers.
本発明の不織布は、構成繊維同士が三次元的に交絡している。三次元的に交絡していることによって不織布としての形態を保持しているため、すなわち、接着剤を用いたり、また、熱接着による熱接着部を有するものでないため、直接肌に触れた際に肌がかぶれたりしにくく、肌触りが良好である。 In the nonwoven fabric of the present invention, the constituent fibers are entangled three-dimensionally. Because it retains its shape as a non-woven fabric by being entangled three-dimensionally, that is, because it does not have an adhesive or a heat-bonded part due to thermal bonding, when directly touching the skin It is hard to get a skin rash and feels good.
本発明の不織布の目付は、特に限定するものではなく、不織布の用途に応じて適宜選択すればよい。一般的には、１０〜２００ｇ／ｍ２程度がよい。 The basis weight of the nonwoven fabric of the present invention is not particularly limited, and may be appropriately selected according to the use of the nonwoven fabric. Generally, about 10 to 200 g / m 2 is preferable.
本発明の不織布は、ステアリン酸アミドが付着されたものである。 Nonwoven fabric of the present invention is stearamide is attached.
不織布へのステアリン酸アミドの付着量は、０．０２５〜０．２質量％の範囲がよい。０．０２５質量％以上とすることにより、本発明の目的を効果的に達成することができ、コシをなくしドレープ性を良好に付与することができる。付着量が０．２質量％を超えると、コシのない不織布を得ることはできるが、不織布を構成する繊維同士の間の滑りが起こりすぎることになって、不織布の機械的物性の極端な低下をまねく恐れがある。 Adhesion amount of stearic acid amide to nonwoven good range of 0.025 to 0.2 mass%. By setting it as 0.025 mass% or more, the objective of this invention can be achieved effectively, a firmness can be eliminated, and drape property can be provided favorably. If the adhesion amount exceeds 0.2% by mass, a non-woven nonwoven fabric can be obtained, but excessive slippage between the fibers constituting the nonwoven fabric will occur, resulting in an extreme decrease in the mechanical properties of the nonwoven fabric. There is a fear that.
以下、本発明の不織布の好ましい製造方法について説明する。すなわち、構成繊維同士が三次元的に交絡してなる不織布に、ステアリン酸アミドを付着させることによって得る。ここで、三次元的に交絡する方法としては、高圧水流の作用によって交絡させることが好ましい。 Hereinafter, the preferable manufacturing method of the nonwoven fabric of this invention is demonstrated. In other words, to obtain a nonwoven fabric constituting fibers becomes entangled three-dimensionally, by attaching a stearic acid amide. Here, as a method of entanglement three-dimensionally, it is preferable to entangle by the action of high-pressure water flow.
まず、セルロース系短繊維を準備し、公知のカード法によって開繊及び集積し、セルロース系短繊維を構成繊維とする不織ウェブを得る。この不織ウェブを、メッシュ状支持体上に担持させる。メッシュ状支持体とは、噴射される高圧水流を排出しうる孔を多数備えたものである。具体的には、粗目織物が用いられ、経糸および緯糸として金属線または太繊度の合成樹脂製フィラメント等を用いて、平織組織または綾織組織等の任意の織組織で製織されたものが採用される。また、粗目織物の目の大きさは任意であるが、１０〜１００メッシュ程度の目開き（孔の大きさ）を持つものを用い、用途に応じて、適宜選択するとよい。例えば、不織布表面に凹凸を付与したり、孔を付与したい場合は、より目開きの大きい１０〜２５メッシュのものを用いるとよく、不織布表面をより平滑なものを得たい場合は、５０〜１００メッシュのものを用いるとよい。 First, cellulosic short fibers are prepared, and opened and accumulated by a known card method to obtain a nonwoven web having cellulosic short fibers as constituent fibers. This nonwoven web is supported on a mesh-like support. The mesh-shaped support is provided with a large number of holes through which a high-pressure water stream to be ejected can be discharged. Specifically, a coarse woven fabric is used, and a fabric woven with an arbitrary woven structure such as a plain weave structure or a twill weave structure using metal wires or filaments made of synthetic resin having a high fineness as warp and weft is used. . The size of the coarse woven fabric is arbitrary, but it may be appropriately selected according to the intended use using a mesh having an opening (hole size) of about 10 to 100 mesh. For example, when it is desired to give irregularities or pores to the nonwoven fabric surface, it is better to use a 10-25 mesh with a larger mesh, and when it is desired to obtain a smoother nonwoven fabric surface, 50-100. Use a mesh.
次いで、メッシュ状支持体上に坦持された不織ウェブに向けて、高圧水流を噴射する。すなわち、メッシュ状支持体が位置する反対側に噴射ノズルを置いて、このノズルから高圧水流を噴射して、直接不織ウェブに当たるようにする。高圧水流は、噴射ノズルから高圧で水を噴射すれば、容易に得ることができる。噴射圧力としては、５〜２０ＭＰａ程度でよい。噴射圧力が低すぎると、構成繊維相互間の交絡が低下し、良好な形態安定性を持つ不織布が得られにくくなる。また、高圧水流は、不織ウェブに一回または複数回施してもよい。高圧水流を施した後は、高圧水流での処理による水を含浸した状態となっているので、マングル等で余剰水分を絞った後、乾燥処理を行う。以上のようにして、構成繊維同士が三次元的に交絡してなる不織布を得る。 Next, a high-pressure water stream is jetted toward the nonwoven web carried on the mesh-like support. That is, an injection nozzle is placed on the opposite side where the mesh-like support is located, and a high-pressure water stream is injected from this nozzle so as to directly hit the nonwoven web. The high-pressure water flow can be easily obtained by jetting water at a high pressure from the jet nozzle. The injection pressure may be about 5 to 20 MPa. If the spray pressure is too low, the entanglement between the constituent fibers decreases, and it becomes difficult to obtain a nonwoven fabric having good shape stability. Alternatively, the high pressure water stream may be applied to the nonwoven web one or more times. After the high-pressure water flow is applied, water is impregnated with the high-pressure water flow, so that the excess water is squeezed with a mangle or the like and then the drying treatment is performed. As described above, a nonwoven fabric in which constituent fibers are entangled three-dimensionally is obtained.
次に、得られた不織布に、所定量のステアリン酸アミドを付着させて、本発明の不織布を得る。その方法としては、たとえばステアリン酸アミドを溶媒中に分散してなるエマルション溶液を不織布に噴霧、含浸、キスコートする方法を挙げることができる。このうちキスコート法は、水平方向の回転式のドライブロールの底部をエマルション中に浸漬させ、ドライブロールの回転によってエマルションを汲み上げ、ロールの頂部に不織布を接触させることで、汲み上げたエマルションを不織布に付着させる方法である。不織布にエマルション溶液を付着させた後は、乾燥処理を施す。 Next, a predetermined amount of stearamide is adhered to the obtained nonwoven fabric to obtain the nonwoven fabric of the present invention. As the method, for example spray stearic acid amide emulsion solution obtained by dispersing in a solvent in the nonwoven, impregnation, may be mentioned a method of kiss coating. Of these, the kiss coat method dipped the bottom of a horizontal rotating drive roll into the emulsion, pumped up the emulsion by rotating the drive roll, and brought the non-woven fabric into contact with the top of the roll, thereby adhering the pumped-up emulsion to the nonwoven fabric. It is a method to make. After the emulsion solution is attached to the nonwoven fabric, a drying treatment is performed.
本発明の不織布によると、セルロース系繊維にて構成される不織布であり、特定量のステアリン酸アミド付着されているため、ドレープ性に優れた、風合いの良好な不織布を得ることができる。特に、本発明において、不織布の構成繊維であるセルロース系繊維が木綿繊維の場合、従来、木綿繊維からなる不織布特有の性質として知られたコシがあり、しっかりとした感触はなく、木綿繊維を用いながらも今までにない風合いを有する不織布を提供することができる。 According to the non-woven fabric of the present invention, it is a non-woven fabric composed of cellulosic fibers, and a specific amount of stearamide is attached, so that a non-woven fabric with excellent drape and good texture can be obtained. In particular, in the present invention, when the cellulosic fiber that is a constituent fiber of the nonwoven fabric is a cotton fiber, there is conventionally known stiffness as a characteristic of the nonwoven fabric made of cotton fiber, there is no firm touch, and the cotton fiber is used. However, it is possible to provide a nonwoven fabric having an unprecedented texture.
次に、実施例に基づき本発明を具体的に説明する。ただし、本発明はこれらの実施例のみに限定されるものではない。 Next, based on an Example, this invention is demonstrated concretely. However, the present invention is not limited to only these examples.
以下の実施例、比較例における各種物性値の測定は、以下の方法により実施した。
（１）目付（ｇ／ｍ２）：標準状態の試料から、縦１０ｃｍ×横１０ｃｍの試料片を１０点作成し、各試料片の質量（ｇ）を秤量し、得られた値の平均値を単位面積あたりに換算して、目付（ｇ／ｍ２）とした。
（２）圧縮剛軟度（ｃＮ）：長さ１０ｃｍ、幅５ｃｍの試料片５点を作成し、各試料片をその長さ方向が周方向となるように曲げて円筒状物とし、各々その端部を接合したものを圧縮剛軟度測定試料とした。定速伸長型引張試験機（オリエンテック社製、テンシロンＵＴＭ-４−１００）を用いて、各測定試料を、その軸方向に圧縮速度５ｃｍ／分で圧縮し、得られた最大荷重の平均値を圧縮剛軟度（ｃＮ）とした。この圧縮剛軟度は値が小さいほどコシがなく、柔軟性が優れることを意味する。
Various physical property values in the following examples and comparative examples were measured by the following methods.
(1) Weight per unit area (g / m 2 ): Ten sample pieces each having a length of 10 cm and a width of 10 cm were prepared from a sample in a standard state, the mass (g) of each sample piece was weighed, and the average value of the obtained values Was converted to a unit area (g / m 2 ).
(2) Compressive bending resistance (cN): 5 sample pieces having a length of 10 cm and a width of 5 cm are prepared, and each sample piece is bent so that the length direction thereof is the circumferential direction to form a cylindrical object. What joined the edge part was used as the compression bending resistance measurement sample. Using a constant-speed extension type tensile tester (Orientec, Tensilon UTM-4-100), each measurement sample was compressed in the axial direction at a compression rate of 5 cm / min, and the average value of the maximum loads obtained. Was the compression bending resistance (cN). The smaller the value of the compression bending resistance, the less the stiffness and the better the flexibility.
実施例１
セルロース系繊維として、単糸繊度１．７デシテックス、平均繊維長２５ｍｍの木綿繊維を準備し、これをランダムカードにて開繊し、約３０ｇ／ｍ２の不織ウェブを得た。得られた不織ウェブを移動式１００メッシュのプラスチック製織物からなるメッシュ状支持体上に載置し、ノズル孔径０．１３ｍｍの噴射孔が孔間隔０．６ｍｍで横一列に配置された噴射装置を用い、噴射圧５．５ＭＰａで３回処理し、次に反転させて反対面より噴射圧５．５ＭＰａで３回処理し三次元的に交絡してなる不織布を得た。
次いで、得られた不織布に、主成分がステアリン酸アミドである油剤（洛東化成工業社製、ステアリン酸アミドを固形分として１０質量％含むもの、商品名：ＵＲＤ−ＳＴ−１００）を、キスコーターを用いて塗布し、ステアリン酸アミドを不織布に対して０．１％付着させた。その後、乾燥温度１２０℃の乾燥機で乾燥した。これによって目付が３０ｇ／ｍ２である不織布を得た。圧縮剛軟度は、１．７ｃＮであった。
Example 1
As the cellulose fiber, a cotton fiber having a single yarn fineness of 1.7 dtex and an average fiber length of 25 mm was prepared, and this was opened with a random card to obtain a nonwoven web of about 30 g / m 2 . The obtained nonwoven web is placed on a mesh-like support made of a movable 100-mesh plastic woven fabric, and spraying nozzles having nozzle hole diameters of 0.13 mm are arranged in a horizontal row with a hole spacing of 0.6 mm. Was used for 3 times at an injection pressure of 5.5 MPa, and then inverted and processed 3 times at an injection pressure of 5.5 MPa from the opposite side to obtain a nonwoven fabric entangled three-dimensionally.
Next, an oil agent whose main component is stearamide (manufactured by Nitto Kasei Kogyo Co., Ltd., containing 10% by weight of stearamide as a solid content, trade name: URD-ST-100) is added to the obtained nonwoven fabric, and kiss coater The stearamide was applied to the non-woven fabric by 0.1%. Then, it dried with the dryer whose drying temperature is 120 degreeC. As a result, a nonwoven fabric having a basis weight of 30 g / m 2 was obtained. The compression bending resistance was 1.7 cN.
