Description

使用済み衛生用品由来の部材を用いた衛生用品Hygiene products using materials derived from used hygiene products
　本発明は、使用済み衛生用品由来の部材を用いた衛生用品に関する。 The present invention relates to a sanitary product using a member derived from a used sanitary product.
　近年、持続可能な開発目標（ＳＤＧｓ）への貢献が求められており、それに対応して、資源の有効利用が進められている。例えば、使用済み衛生用品（例示：使い捨ておむつ、失禁パッド、生理用ナプキン、パンティーライナーのような吸収性物品）からパルプ繊維や高吸水性ポリマーなどをリサイクルする技術が知られている。そのような技術としては、例えば、特許文献１に、高吸水性ポリマーの再生方法、高吸水性リサイクルポリマーの製造方法、及びアルカリ金属イオン供給源の使用が開示されている。この方法は、使用済み衛生用品由来のパルプ繊維及び高吸水性ポリマーを、それぞれリサイクルパルプ繊維及び高吸水性リサイクルポリマーとして再生（製造）している。 In recent years, contributions to sustainable development goals (SDGs) have been required, and in response to this, effective use of resources is being promoted. For example, there is known a technique for recycling pulp fibers, highly absorbent polymers, and the like from used sanitary goods (eg, disposable diapers, incontinence pads, sanitary napkins, absorbent articles such as panty liners). As such a technique, for example, Patent Document 1 discloses a method for regenerating a highly water-absorbent polymer, a method for producing a highly water-absorbent recycled polymer, and the use of an alkali metal ion source. This method regenerates (manufactures) pulp fibers and highly water-absorbent recycled polymers derived from used sanitary products as recycled pulp fibers and highly water-absorbent recycled polymers, respectively.
特開２０１９－１３５０４６号公報Japanese Unexamined Patent Publication No. 2019-135044
　特許文献１では、使用済み衛生用品から資材を回収する場合、パルプ繊維及び高吸水性ポリマーは他の資材から分離され、衛生用品のリサイクルパルプ繊維及び高吸水性リサイクルポリマーとして再利用できる。しかし、それ以外の非特定資材は、種々の資材が破砕され混合された状態で他の資材から分離されるので、衛生用品の資材として再利用することは必ずしも容易ではない。そのため、衛生用品の表面シートや外面シート（裏面シートを含む）などに使用される不織布やフィルムとしては、分離された資材が再利用されるのではなく、合成樹脂のような石油由来の材料から新たに形成された資材が用いられる場合がある。ところが、石油の再生は実質的に不可能であるから、合成樹脂のような石油由来の材料は持続可能な材料とは必ずしもいえない。したがって、持続可能な開発目標に貢献し得る衛生用品の提供に関して、改善の余地がある。 In Patent Document 1, when the material is recovered from the used sanitary goods, the pulp fiber and the highly water-absorbent polymer are separated from other materials and can be reused as the recycled pulp fiber and the highly water-absorbent recycled polymer of the sanitary goods. However, other non-specific materials are not always easy to reuse as materials for hygiene products because various materials are crushed and separated from other materials in a mixed state. Therefore, as the non-woven fabric and film used for the front surface sheet and outer surface sheet (including the back surface sheet) of sanitary products, the separated material is not reused, but from petroleum-derived materials such as synthetic resin. Newly formed materials may be used. However, petroleum-derived materials such as synthetic resins are not always sustainable materials because petroleum regeneration is virtually impossible. Therefore, there is room for improvement in the provision of hygiene products that can contribute to sustainable development goals.
　本発明は、使用済み衛生用品由来の部材を用いた衛生用品において、資源を有効利用でき、かつ、持続可能な材料を使用できる衛生用品を提供することにある。 The present invention is to provide a sanitary product using a member derived from a used sanitary product, which can effectively utilize resources and can use sustainable materials.
　本発明は、表面シートと、外面シートと、パルプ繊維及び高吸水性ポリマーを含む吸収体と、を備える、使用済み衛生用品由来の部材を含む衛生用品であって、前記吸収体は、前記パルプ繊維又は前記高吸水性ポリマーが前記使用済み衛生用品由来の部材としてのリサイクルパルプ繊維又は高吸水性リサイクルポリマーを含み、前記表面シート又は前記外面シートは、バイオ由来の材料を含むバイオ由来シートであり、前記バイオ由来シートから前記吸収体に向かって測定したときのΔＹＩが標準白板に対して０～９の範囲である、衛生用品、である。 The present invention is a sanitary product comprising a member derived from a used sanitary product, comprising a surface sheet, an outer surface sheet, and an absorber containing pulp fibers and a highly water-absorbent polymer, wherein the absorber is the pulp. The fiber or the highly water-absorbent polymer contains recycled pulp fiber or a highly water-absorbent recycled polymer as a member derived from the used sanitary goods, and the surface sheet or the outer surface sheet is a bio-derived sheet containing a bio-derived material. , A sanitary product in which ΔYI measured from the bio-derived sheet toward the absorber is in the range of 0 to 9 with respect to a standard white plate.
　本発明により、使用済み衛生用品由来の部材を用いた衛生用品において、資源を有効利用でき、かつ、持続可能な材料を使用できる衛生用品を提供することができる。 INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a hygiene product using a member derived from a used hygiene product, which can effectively utilize resources and can use sustainable materials.

When the pulp fiber contains recycled pulp fiber, the ratio of the recycled pulp fiber to the pulp fiber is, for example, 20 to 100% by mass, preferably 50 to 100% by mass, and more preferably 75 to 100% by mass. This is from the perspective of effective use of resources. The recycled pulp fiber and the highly water-absorbent recycled polymer are not particularly limited, and examples thereof include the recycled pulp fiber and the highly water-absorbent recycled polymer described in Patent Document 1 (Japanese Unexamined Patent Publication No. 2019-135044). The polymer is a polymer because the state of internal cross-linking differs between the highly water-absorbent recycled polymer (water-absorbed and dehydrated at least once) and the virgin highly water-absorbent polymer (water-absorbed and dehydrated at least once). It is possible to distinguish by measuring the soluble content of. For example, the soluble content of a virgin highly water-absorbent polymer generally used for hygiene products is 10% by mass or less, whereas the soluble content of the highly water-absorbent recycled polymer of Patent Document 1 is about 15% by mass. It gets higher. However, the method for measuring the soluble component is the water-soluble component (Ext) specified in ERT (EDANA Recommended Test Method) 470.2-02. Recycled pulp fibers are relatively easy to whiten and can be distinguished. For example, the recycled pulp fiber of Patent Document 1 has a small ΔYI (in other words, a low lignin content), that is, it has a high whiteness and can be distinguished.

It is higher than the absorption performance of conventional hygiene products that have a body. However, the same size of the two absorbers means that the sizes of the longitudinal direction L, the width direction W and the thickness direction T match each other within ± about 5%, or the volume is within ± about 15%. It means that they match with. Further, the same basis weight means that the basis weights match within ± about 15%. Here, the recycled pulp fiber has a lower ash content than the virgin pulp fiber. Therefore, when recycled pulp fiber and virgin pulp fiber are used in the same volume and the same basis weight in the absorber, the amount of pulp fiber is larger in the case of using the recycled pulp fiber than in the case of using the virgin pulp fiber. Become. That is, the absorption performance is improved. As a result, it is possible to give the user a sense of security that the body fluid is unlikely to leak, and it is possible to further suppress the psychological resistance caused by the product being recycled from used hygiene products.

Absorption performance of bags etc. can be improved. In addition, when improving the absorption performance with a highly water-absorbent polymer using a bio-derived material, the degree of cross-linking is adjusted and the surface is treated during the production of the highly water-absorbent polymer, and multiple types of highly water-absorbent polymers are used. Absorption performance can be improved by mixing. These methods have the potential to complicate the manufacturing process, increase the workload, and increase the cost, but the improvement in absorption performance brought about by these methods makes it difficult for the user to leak body fluids. It gives a sense of security and can further suppress the psychological resistance caused by being a recycled product.
