Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary paper coated with a plurality of chemical solutions having different compositions and a method for manufacturing the same.

[0002]

2. Description of the Related Art For the purpose of improving the texture of sanitary paper such as tissue paper and toilet paper,
It has already been performed to apply a wetting agent, a softening agent, a smoothing agent or the like to sanitary paper such as tissue paper or toilet paper by a printing method such as flexo or gravure or a spray method.

It is also already known to apply a fragrance or deodorant or a fragrance or deodorant embedded with microcapsules by a printing method or a spray method.

[0004] In recent years, in order to add added value with sanitary paper, attempts have been made to apply the above-mentioned chemical solutions having different functions to the same sheet. However, there are hydrophilic agents such as softeners and hydrophobic agents such as fragrances. The difference is that when both are mixed, the liquid medicine becomes non-uniform, or when a fragrance, etc. embedded in microcapsules is mixed with a softener, the skeleton component of the microcapsule reacts with the softener, etc. The film agent (skeleton component) of the capsule was destroyed, and it was difficult to fully exhibit the functions of the drug solutions having different functions.

Further, even with the same texture-improving agent, a wetting agent which gives a moist feeling to the sheet and a softening agent which gives suppleness,
There is a smoothing agent that gives a smooth feeling, and there is an individual difference in which tactile feeling is preferred. Therefore, two or three kinds of these three kinds of texture improvers are blended in a commercially available lotion tissue (a tissue to which a texture improver is added). However, this method has problems that the amount used and the drugs that can be used are limited due to the problem of stability of the mixed solution, that the effects of the drugs cancel each other out, and that the effects of a single drug stand out.

As a method of compensating for the above-mentioned drawbacks, there is a method of first applying or applying a texture improving agent such as a softening agent and then again applying or applying a perfume or the like, but the process becomes complicated. Further, there is a problem that the reduction in bulk, which is an important characteristic of sanitary paper, is large.

[0007]
