In the absorbent body of the present invention, gelatin is stably fixed to cellulose fibers and uniformly dispersed. Therefore, handling is easy and the absorption performance is excellent.
本発明に係る吸収体は、セルロース繊維とゼラチンを含有するものである。セルロース繊維とゼラチンは吸収性材料として機能し、特にゼラチンは水性液体を吸収し固定することができる。本発明によれば、ゼラチンが安定して固定され均一に分散された吸収体を簡単に得ることができる。以下、本発明の吸収体の製造方法について説明する。 The absorber according to the present invention contains cellulose fibers and gelatin. Cellulose fibers and gelatin function as absorbent materials, in particular gelatin can absorb and fix aqueous liquids. According to the present invention, it is possible to easily obtain an absorbent body in which gelatin is stably fixed and uniformly dispersed. Hereinafter, the manufacturing method of the absorber of this invention is demonstrated.
本発明の吸収体の製造方法は、ゼラチン溶液をセルロース繊維集合体に含ませて複合体を得る工程（ゼラチン混合工程）と、複合体を解砕する工程（解砕工程）と、解砕した複合体を成形する工程（成形工程）を有するものである。 In the method for producing an absorbent body of the present invention, a gelatin solution is included in a cellulose fiber aggregate to obtain a composite (gelatin mixing step), a step of crushing the composite (crushing step), and crushing It has the process (molding process) which shape | molds a composite.
ゼラチン混合工程では、ゼラチン溶液をセルロース繊維集合体に含ませて複合体を得る。ゼラチン混合工程ではセルロース繊維集合体にゼラチン溶液が加えられ、ゼラチン溶液を含んだセルロース繊維集合体が複合体として得られる。得られた複合体は、セルロース繊維集合体を構成するセルロース繊維の表面にゼラチン溶液が被覆されたもの、あるいは、セルロース繊維内部にゼラチン溶液が含浸したものとなり、セルロース繊維にゼラチンが安定して固定される。 In the gelatin mixing step, the gelatin solution is included in the cellulose fiber aggregate to obtain a composite. In the gelatin mixing step, a gelatin solution is added to the cellulose fiber aggregate, and a cellulose fiber aggregate containing the gelatin solution is obtained as a composite. The resulting composite has a cellulose fiber surface coated with a gelatin solution or a cellulose fiber impregnated with a gelatin solution, and the gelatin is stably fixed to the cellulose fiber. Is done.
ゼラチンは動物の骨や皮膚に含まれるコラーゲンが変性したタンパク質の一種である。本発明で用いられるゼラチンとしては一般に市販されているゼラチンを用いればよく、牛由来、豚由来、鶏由来、魚由来等のゼラチンを用いることができる。また、例えばゼラチンの機能改善のために、変性されたゼラチンを用いてもよい。 Gelatin is a type of protein in which collagen contained in animal bones and skin is denatured. As the gelatin used in the present invention, commercially available gelatin may be used, and gelatin derived from cattle, pigs, chickens, fish and the like can be used. Further, for example, modified gelatin may be used to improve the function of gelatin.
ゼラチン溶液は、ゼラチンを溶媒に溶解させて調製すればよい。ゼラチン溶液に用いる溶媒は水を含んでいることが好ましい。例えば、ゼラチン溶液の溶媒は水に加えてアルコールを含有していてもよく、この場合、ゼラチン溶液のゲル化の程度を抑えることが可能となる。なお製造容易性の点から、ゼラチン溶液の溶媒としては水を用いることが好ましい。また、ゼラチンの溶解性を高めるために、ゼラチン溶液の温度は５０℃以上とすることが好ましく、６０℃以上とすることがより好ましい。 The gelatin solution may be prepared by dissolving gelatin in a solvent. The solvent used for the gelatin solution preferably contains water. For example, the solvent of the gelatin solution may contain alcohol in addition to water, and in this case, the degree of gelation of the gelatin solution can be suppressed. From the viewpoint of ease of production, water is preferably used as the solvent for the gelatin solution. In order to increase the solubility of gelatin, the temperature of the gelatin solution is preferably 50 ° C. or higher, and more preferably 60 ° C. or higher.
セルロース繊維集合体は、セルロース繊維が塊状に一体化されたものであり、例えば、綿繊維、木材繊維、ケナフ繊維等の集合体を用いることができる。好ましくは、セルロース繊維集合体としては、パルプシートを用いる。パルプシートはパルプがシート状に成形されたものであり、製紙用原料や使い捨ておむつ等の吸収体の原料、あるいは様々なセルロース含有製品の原料として市場に流通しており、入手が容易である。パルプシートを構成するパルプは、木材パルプであっても非木材パルプであってもよく、また古紙パルプであってもよい。好ましくは、木材パルプから成形されたパルプシートを用いる。 Cellulose fiber aggregates are those in which cellulose fibers are integrated into a lump. For example, aggregates of cotton fibers, wood fibers, kenaf fibers, and the like can be used. Preferably, a pulp sheet is used as the cellulose fiber aggregate. Pulp sheets are obtained by forming pulp into sheets, and are readily available because they are distributed in the market as raw materials for papermaking, raw materials for absorbents such as disposable diapers, and raw materials for various cellulose-containing products. The pulp constituting the pulp sheet may be wood pulp, non-wood pulp, or waste paper pulp. Preferably, a pulp sheet formed from wood pulp is used.
ゼラチン混合工程では、セルロース繊維集合体を解砕せずにそのまま姿でゼラチン溶液と接触させ、ゼラチン溶液をセルロース繊維集合体に含ませることが、製造が簡単に行える点から好ましい。ゼラチン溶液をセルロース繊維集合体に含ませる方法としては、セルロース繊維集合体をゼラチン溶液に含浸する方法や、ゼラチン溶液をセルロース繊維集合体に塗布する方法等が挙げられる。 In the gelatin mixing step, it is preferable that the cellulose fiber aggregate is brought into contact with the gelatin solution as it is without being crushed and the gelatin solution is contained in the cellulose fiber aggregate from the viewpoint of easy production. Examples of the method of incorporating the gelatin solution into the cellulose fiber aggregate include a method of impregnating the cellulose fiber aggregate in the gelatin solution, a method of applying the gelatin solution to the cellulose fiber aggregate, and the like.
セルロース繊維集合体をゼラチン溶液に含浸する場合は、ゼラチン溶液中にセルロース繊維集合体を浸漬することで、ゼラチン溶液を含んだセルロース繊維集合体（複合体）が得られる。この方法は、セルロース繊維集合体に多量のゼラチン溶液を含ませる場合に有効である。 When the cellulose fiber aggregate is impregnated in the gelatin solution, the cellulose fiber aggregate (composite) containing the gelatin solution is obtained by immersing the cellulose fiber aggregate in the gelatin solution. This method is effective when a large amount of gelatin solution is contained in the cellulose fiber aggregate.
ゼラチン溶液をセルロース繊維集合体に塗布する場合は、コーターやスプレー等を用いてゼラチン溶液をセルロース繊維集合体に塗布することにより、ゼラチン溶液を含んだセルロース繊維集合体（複合体）が得られる。この方法では、セルロース繊維集合体にあまり多量のゼラチン溶液を含ませることはできないが、ゼラチン溶液を塗布するための装置が比較的簡単なものとなるため、製造上簡単にゼラチン溶液をセルロース繊維集合体に含ませるようにすることができる。 When the gelatin solution is applied to the cellulose fiber aggregate, the cellulose fiber aggregate (composite) containing the gelatin solution is obtained by applying the gelatin solution to the cellulose fiber aggregate using a coater or a spray. In this method, the cellulose fiber aggregate cannot contain a very large amount of gelatin solution, but since the apparatus for applying the gelatin solution becomes relatively simple, it is easy to manufacture the gelatin solution. It can be included in the body.
ゼラチン溶液をセルロース繊維集合体に含ませることにより得られた複合体は、解砕工程で解砕される。解砕工程により、複合体が解砕されるとともに、解砕した複合体が混合される。そのため、ゼラチン混合工程で得られた複合物がゼラチンを不均一に含むものであっても、解砕工程により複合体の解砕物が混合されて、解砕した複合体全体中にゼラチンが均一分散されやすくなる。 The composite obtained by including the gelatin solution in the cellulose fiber aggregate is crushed in the crushing step. In the crushing step, the complex is crushed and the crushed complex is mixed. Therefore, even if the composite obtained in the gelatin mixing step contains gelatin non-uniformly, the crushed composite is mixed in the pulverization step, and the gelatin is uniformly dispersed throughout the crushed composite. It becomes easy to be done.
複合体の解砕は、パルプシート等のセルロース繊維集合体を解砕する方法として公知の方法を採用することができる。従って、吸収体の製造ラインにパルプシート等の解砕装置が既に備わっている場合は、既存の装置を用いて複合体を解砕することができる。 For crushing the composite, a known method can be adopted as a method for crushing a cellulose fiber aggregate such as a pulp sheet. Therefore, when the absorber production line is already equipped with a crushing device such as pulp sheet, the composite can be crushed using the existing device.
複合体の解砕方法としては、湿式解砕、乾式解砕、含水軟化解砕等が挙げられる。なお、比較的簡単に解砕を行える点から、乾式解砕を用いることが好ましい。また、乾式解砕を採用すれば、解砕の際に発生する摩擦熱によって、セルロース繊維集合体に含ませたゼラチン溶液を乾燥させることも可能となる。乾式解砕を行うための解砕機としては、例えば、ジェットミル、ハンマーミル、カッティングミル、アトリッションミル、ボールミル等を用いればよい。乾式解砕を行う場合、解砕機に熱風を導入したり、解砕機を外部から加熱して、セルロース繊維集合体に含ませたゼラチン溶液の乾燥を促進してもよい。 Examples of the method for crushing the composite include wet crushing, dry crushing, and hydrous softening crushing. In addition, it is preferable to use dry crushing from the viewpoint that crushing can be performed relatively easily. If dry crushing is employed, the gelatin solution contained in the cellulose fiber aggregate can be dried by frictional heat generated during crushing. As a crusher for performing dry crushing, for example, a jet mill, a hammer mill, a cutting mill, an attrition mill, a ball mill or the like may be used. When dry crushing, hot air may be introduced into the crusher, or the crusher may be heated from the outside to promote drying of the gelatin solution contained in the cellulose fiber aggregate.
解砕した複合体は、成形工程で成形する。解砕した複合体を成形することにより吸収体が得られる。このようにして、ゼラチンが均一分散され、しかもゼラチンが安定してセルロース繊維に固定された吸収体を簡単に得ることができる。 The crushed composite is molded in a molding process. An absorbent body is obtained by molding the crushed composite. In this way, it is possible to easily obtain an absorbent body in which gelatin is uniformly dispersed and gelatin is stably fixed to cellulose fibers.
成形工程では、例えば、解砕した複合体を型に入れて、所望する形状に成形すればよい。吸収体を使い捨ておむつ等の吸収性物品に用いる場合は、解砕した複合体を、略長方形、砂時計型、ひょうたん型、羽子板型等に成形すればよい。 In the molding step, for example, the crushed composite may be put in a mold and molded into a desired shape. When the absorbent body is used for an absorbent article such as a disposable diaper, the crushed composite may be formed into a substantially rectangular shape, an hourglass shape, a gourd shape, a battledore shape, or the like.
本発明の製造方法は、ゼラチン混合工程と解砕工程の間に複合体を乾燥する工程を設けてもよく、解砕工程と成形工程の間に解砕した複合体を乾燥する工程を設けてもよい。これらの乾燥工程は任意に設けられるものであり、両方設けてもよいし、どちらか一方のみ設けてもよいし、乾燥工程を設けなくてもよい。複合体または解砕した複合体を乾燥する場合、その乾燥温度は６０℃以上が好ましく、８０℃以上がより好ましく、また２００℃以下が好ましく、１６０℃以下がより好ましい。 In the production method of the present invention, a step of drying the composite may be provided between the gelatin mixing step and the crushing step, and a step of drying the crushed composite between the crushing step and the molding step may be provided. Also good. These drying steps are provided arbitrarily, and both may be provided, only one of them may be provided, or the drying step may not be provided. When drying the composite or the crushed composite, the drying temperature is preferably 60 ° C. or higher, more preferably 80 ° C. or higher, 200 ° C. or lower, more preferably 160 ° C. or lower.
以上説明した製造方法により、本発明に係る吸収体を得ることができる。つまり、本発明の吸収体は、セルロース繊維とゼラチンを含有し、ゼラチン溶液をセルロース繊維集合体に含ませて得られた複合体を解砕して成形することにより得られるものである。また、本発明の吸収体は、ゼラチンが被覆されたセルロース繊維が均一分散されているものである。セルロース繊維集合体としてパルプシートを用いれば、本発明の吸収体はセルロース繊維としてパルプ繊維を含むものとなる。本発明の吸収体の好適条件は、上記の説明と同様である。 The absorber which concerns on this invention can be obtained with the manufacturing method demonstrated above. That is, the absorbent body of the present invention is obtained by pulverizing and molding a composite containing cellulose fibers and gelatin and containing a gelatin solution in the cellulose fiber aggregate. The absorbent body of the present invention is one in which cellulose fibers coated with gelatin are uniformly dispersed. If a pulp sheet is used as the cellulose fiber aggregate, the absorbent body of the present invention includes pulp fibers as cellulose fibers. Suitable conditions for the absorbent body of the present invention are the same as described above.
本発明の吸収体は、ゼラチンがセルロース繊維に安定して固定され、均一に分散されたものとなるため、取り扱いが容易であり、吸収性能にも優れたものとなる。また、吸収体に含まれるゼラチンとセルロース繊維は生分解性を有するため、環境負荷が少ないものとなる。 The absorbent body of the present invention is one in which gelatin is stably fixed to cellulose fibers and uniformly dispersed, and therefore it is easy to handle and has excellent absorption performance. Moreover, since gelatin and cellulose fiber contained in the absorbent body are biodegradable, the environmental load is small.
なお吸収体にゼラチンが均一に分散されているとは、吸収体中のゼラチン含有率のばらつきが２０％以内（好ましくは１０％以内）に抑えられていることを意味する。具体的には、吸収体の一方面と他方面のそれぞれについて周縁近傍の４点（これらは互いにできるだけ離間していることが好ましい）と中央の１点の合計１０点からサンプルを採取し、各サンプルのゼラチン含有率を測定したときに、ゼラチン含有率の最大値と最小値が平均値の±１０％以内（好ましくは±５％以内）にあればよい。 Note that that the gelatin is uniformly dispersed in the absorber means that the dispersion of the gelatin content in the absorber is suppressed to within 20% (preferably within 10%). Specifically, samples are taken from a total of 10 points including 4 points in the vicinity of the periphery of each of the one side and the other side of the absorber (which are preferably separated from each other as much as possible) and one point at the center. When the gelatin content of the sample is measured, the maximum and minimum values of the gelatin content may be within ± 10% (preferably within ± 5%) of the average value.
本発明の吸収体には、ゼラチンとセルロース繊維以外の他の成分が含まれていてもよく、例えば、ゼラチン以外の吸水性樹脂（例えば、ポリアクリル酸系吸水性樹脂）やセルロース繊維以外の繊維（例えば、合成繊維）が含まれていてもよい。 The absorbent body of the present invention may contain components other than gelatin and cellulose fibers. For example, water absorbent resins other than gelatin (for example, polyacrylic acid-based water absorbent resins) and fibers other than cellulose fibers. (For example, synthetic fibers) may be included.
本発明はまた、本発明の吸収体を備えた吸収性物品も提供する。吸収性物品としては、使い捨ておむつ、尿パッド、生理用ナプキン等が挙げられる。吸収性物品は、例えば、液透過性のトップシートと液不透過性のバックシートの間に本発明の吸収体が配されて構成される。吸収体は、そのままの状態でトップシートとバックシートの間に配されてもよく、ティッシュ等の液透過性シートに包んで、これがトップシートとバックシートの間に配されてもよい。 This invention also provides the absorbent article provided with the absorber of this invention. Examples of absorbent articles include disposable diapers, urine pads, sanitary napkins and the like. The absorbent article is configured, for example, by arranging the absorbent body of the present invention between a liquid-permeable top sheet and a liquid-impermeable back sheet. The absorbent body may be arranged between the top sheet and the back sheet as it is, or may be wrapped in a liquid-permeable sheet such as a tissue and disposed between the top sheet and the back sheet.
本発明に係る吸収体は、使い捨ておむつ等の吸収性物品、ペット用の排泄シート、食品のドリップ吸収シート、掃除用の水吸収材、土木用の止水材等に用いることができる。 The absorbent body according to the present invention can be used for absorbent articles such as disposable diapers, excretory sheets for pets, drip absorbent sheets for foods, water absorbents for cleaning, and waterstop materials for civil engineering.
