  • the cushioning property in the thickness direction increases, but since the fibers on the surface become sparse and the roughness increases, it is difficult to further improve the softness and smoothness by simply reducing the density of the paper. .. Further, if the density of the paper is excessively reduced, the strength tends to be insufficient, and the firm feeling tends to be deteriorated. Further, when a large amount of the bulking agent is used to reduce the density of the paper, problems such as deterioration of the peelability from the dryer during papermaking are likely to occur.

This is because if it is less than 14.0 g/m 2 , a feeling of thickness and a feeling of bulkiness are hard to be expressed, and it is difficult to feel a difference from a low-priced general-purpose product.

We have found that it is a high content that cannot be seen. If it is less than 0.15% by mass, the effect of improving the softness and smoothness is small, and if it exceeds 0.45% by mass, the cost is high and the production becomes difficult.
  • the tissue paper according to the present invention has many oily components extracted by diethyl ether due to the internal additive. That is, a large amount of an oily component coats the surface of the pulp fiber, and the film of the oily component exerts a strong effect on the smoothness of the surface and the action of weakening the hydrogen bond between pulps, resulting in high softness. Further, since there are many oily components that cover the surface of the pulp fiber, the moisture of the pulp is retained by the emollient effect. That is, although the oily component itself does not have a hygroscopic effect, the pulp fiber itself does not interfere with the effect of retaining the absorbed moisture, and the moist feeling is not excessively lowered.
  • the softening agent containing fats and oils in order to increase the content of oily components, it is possible to increase the addition amount of the softening agent containing fats and oils or increase the fats and oils components in the softening agent, but the fats and oils extracted with diethyl ether have a low polarity. Since it is a substance, generally, even if the amount of the softening agent added is increased, the fixing rate to the fiber cannot be increased. In addition, the adherability to the dryer may be reduced and the workability may be deteriorated. Therefore, in order to increase the fixing rate of the oil/fat extracted with diethyl ether on the fiber, it is preferable to increase the chances of contact between the pulp and the oil/fat.
