Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to thin paper such as tissue paper and toilet paper, which is excellent in cosmetics and excellent in texture, and a method for producing the same. More specifically, when printing on thin paper using a printing machine such as flexo or gravure, a mixture of a printing ink and a lotion chemical containing a wet component and / or a soft component or a smooth component is applied in a pattern. And a method for producing the same.

[0002]

2. Description of the Related Art Tissue paper, toilet paper,
Thin papers such as paper towels and paper napkins are often printed in various patterns by flexo, gravure, or the like in order to enhance cosmetic effects and add value to products.

In order to improve the texture of the thin paper, a lotion liquid containing a wetting agent, a softening agent, a smoothing agent or the like as a main component is often applied in the above-described printing pattern or by a spray method. I have. However, conventionally, printing or lotion coating is a completely separated technique and has not been performed simultaneously. Further, if these processes are performed in two separate steps, there is a problem that the number of times the paper web passes between the rolls increases, and the bulkiness, which is an important property of the thin paper, is impaired.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to develop and integrate such a conventional technique, and an object of the present invention is to provide skin-friendly thin paper which is excellent in cosmetics and texture.

That is, the present invention provides a tissue paper which is not only a cosmetic effect but also has an excellent texture by applying a lotion chemical at the same time as printing ink during printing.
Provide toilet paper, etc.

[0006]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, when printing tissue paper, toilet paper, paper napkin, etc. by flexo, gravure, etc., the printing ink was used. The present inventors have found that by applying a mixture of a lotion solution to a sheet of paper, it is possible to obtain a product that is excellent both in cosmetics and in texture, and has accomplished the present invention.

[0007] The printing ink used in the present invention is not particularly limited, but when the present invention is applied to toilet paper, an aqueous type is preferred in order to quickly disperse the sheet in water.

[0008] As the wetting agent of the lotion solution used in the present invention, polyhydric alcohols such as glycerin, diglycene, sorbit, sorbitan and pentaerythritol are mentioned. Further, a quaternary ammonium salt, an amine salt or an amine may be added to impart flexibility to the lotion solution. In addition, a polysiloxane such as dimethylpolysiloxane, amino-modified silicone, or polyether silicone oil may be added for more smoothness.

The amount of printing ink or lotion applied to the sheet depends on the ratio of the printing pattern to the sheet.
As the print pattern, any one such as a geometric pattern, an illustration, a picture, and a character can be selected. The application of the printing ink and the lotion chemical solution and the processing into the final product may be separate processes or may be the same process. The mixing ratio of the printing ink and the lotion chemical may be arbitrary, but preferably the ratio of the printing ink is in the range of 40 to 60%.

[0010]

As described above, the tissue paper, toilet paper, paper napkin and the like according to the present invention are excellent in aesthetic appearance and excellent in texture because the lotion liquid is applied simultaneously with the printing ink on the sheet surface. There is. In the case of tissue paper, it can be used comfortably even when it is sensitive to irritation due to a nose due to a cold or pollen allergy, etc.There is little frictional resistance to skin and mucous membranes even when toilet paper is sensitive to irritation due to hemorrhoids It can be used happily because it is moist.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION As components of a lotion drug solution used in the present invention, polyhydric alcohols such as glycerin, sorbit, sorbitan, and pentaerythritol are used. In addition, quaternary ammonium, amine salts, amines and the like, and dimethylpolysiloxy acid of polysiloxy acid, amino-modified silicone, polyether silicone oil and the like are used.

The following table shows an example of the composition of the lotion solution of the present invention. As a printing ink, an oil type, a solvent type, or a water-soluble type is used.

The case where the present invention is applied to toilet paper will be described below, but the present invention is not limited thereto.
