Bactericidal polymer nanofiber aggregate and dry toilet paper using the same

Abstract

The subject of the present invention is to provide a sterilizing material that can be mass-produced in simple steps using an easy-to-operate device by using polymer nanofiber aggregates instead of microcapsules, which are complicated in the production process, and sanitary paper using the same. The solution is that the bactericidal polymer nanofiber aggregate of the present invention has an aggregate in a dry state in which hollow polymer nanofibers 1 having openings at both ends are aggregated. A bactericidal coating layer 3 containing a quaternary ammonium salt having at least one of a carboxyl group and a hydroxyl group is provided on the inner surface portion and the outer surface portion of the hollow polymer nanofiber 1 . The sanitary paper of the present invention is made of wood fibers in a dry state and the above-mentioned bactericidal polymer nanofiber aggregate is blended.

Description

technical field [0001] The present invention relates to an aggregate provided with a bactericidal coating layer such as a surfactant on nanofibers formed of polymer materials such as PP (polypropylene), and a hygienic product incorporating the bactericidal polymer nanofiber aggregate. use paper. Background technique [0002] In recent years, nanofibers, which have attracted attention, are not only used alone but also in the field of composite materials in a wide range of fields such as general-purpose products, filter materials, electronic parts, automotive parts, and medical biomaterials due to their own physical properties. Applications, application development are also studied in various corporate or national projects. [0003] The main features of nanofibers include 1) super specific surface area effect (high adsorption, strong adhesion, high molecular recognition), 2) nano size effect (low pressure loss, high transparency), 3) supramolecular arrangement Effects (high ...

AI Technical Summary

Problems solved by technology

[0017] Any of the above-mentioned microencapsulation technologies has the problem that the process is complicated and difficult to mass-produce in industrial production

[0018] In recent years, new functional composite materials (elements) that use the above-mentioned nanofibers instead of the microcapsules described above have been urgently needed, but have not yet been realized

[0019] On the other hand, conventionally, as sanitary paper having a bactericidal component, wet wet paper impregnated with an aqueous solution such as ethanol or sodium hypochlorite has been commercially available, but such wet sanitary paper has the following problem: the weight of the product becomes heavy , and once the product provided in a sealed state is opened, the storage time is shortened. In addition, since the paper is soaked in an aqueous solution, it is impossible to use water-insoluble components, etc.

[0020] In addition, the conventional wet toilet paper needs to mix about 10 times the bactericidal component solution with pulp as a raw material, which raises the cost, and it is difficult to adjust the compounding amount of the bactericidal component.
