Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fibrous web product which can be used for tissue paper, toilet paper, sebum removing paper and the like having excellent wiping-off property for sebum and water, and a method for producing the same.

[0002]

2. Description of the Related Art In recent years,
Against the background of increasing awareness for cleanliness and comfort of bare skin, it is desired to provide a fiber web product that has a high ability to wipe off sebum and moisture and that is soft to the touch. In particular, people with normal skin, including those with oily skin, have a lot of sweat and oil secretion during hot and humid seasons, which makes the skin feel silky and has a refreshing feel to the skin. Realization of is desired. In addition, when using a flush toilet with a cleaning device, which has been popularized in recent years, shower water may remain on the skin and cause discomfort. Even in such a case, there is a demand for a fiber web product which has a high ability to wipe off moisture, has a silky feel, and makes the skin refreshed.

As a fibrous web product of this type, there is a degreasing paper for makeup as described in, for example, JP-A-6-319664. This degreasing paper is prepared by blending an inorganic filler with a pulp raw material whose main component is a highly sebum-absorbing vegetable fiber to prepare a paper stock, and the paper obtained by papermaking should have a tenacity of not less than a predetermined value. Thus, a greasing paper excellent in oil absorption, flexibility and strength is obtained. These degreasing papers are dedicated papers for removing sebum, have a high density and have a high fat absorption rate, but have almost no moisture absorption. In addition, since these products are generally expensive, they are not suitable for a wide range of applications such as tissue paper substitutes other than greasing paper.

Further, as a tissue paper which is not exclusively for degreasing but has a high moisturizing property, the applicant of the present invention has disclosed that in Japanese Patent Laid-Open No.
Fibrous web products such as those found in 156596 and U.S. Pat. No. 5,449,551 are known to be moist and less irritating to the skin. This fibrous web product is moist and smooth due to plasticization of the pulp due to moisture absorption, but has a low dryness,
The ability to wipe dirt such as sebum is low.

Further, a wet tissue containing a powder is also known, and after the skin is wiped off, volatile components such as water are volatilized from the surface of the skin, and the powder left on the skin causes a dry feeling. There are also products. However, this product is inherently used in a wet state with excessive water content, and requires a closed container for preventing drying and special packaging, and thus tends to be expensive.

[0006] On the other hand, a paper white cloth which transfers the white powder applied to the paper to the skin at the time of use is also known, but it has a great character as a mobile white cloth and is not suitable for uses such as tissue paper.

Therefore, the present invention solves these problems of the prior art, is excellent in the ability to wipe off sebum and water, and can be used for various purposes including tissue paper, and a low-cost fiber web product and a method for producing the same. Is to provide.
