工方法がすでに知られている。2. Description of the Related Art Conventionally, as a means for increasing the flexibility of tissue paper, a softening agent is added to a pulp slurry, a wet paper before crepe treatment or a dry coating after crepe treatment is applied by spraying or printing method. The coating method is already known.
【０００３】前者の方法では、柔軟剤にカチオン系界面
活性剤が主に使用される。カチオン系界面活性剤の代表
例として四級アンモニウム塩、アミン塩などが挙げられ
る。In the former method, a cationic surfactant is mainly used as a softening agent. Representative examples of cationic surfactants include quaternary ammonium salts and amine salts.
【０００４】後者の方法では、カチオン系界面活性剤に

るために吸水性は悪くなる。However, in any of the methods, the fact that the softening agent is used to improve the flexibility is due to a common mechanism because the softening agent is a surfactant, and also involves various problems. . These are described below.
Taking a cationic surfactant as an example, a cationic group, which is a hydrophilic group, is adsorbed on the pulp fiber surface, and lipophilic groups are arranged outward. Microscopically, when this lipophilic group is present between the fibers, the frictional resistance between the fibers decreases, and the sheet feels soft by giving a slimy feeling to the sheet. However, the lipophilic group between the fibers inhibits the hydrogen bonding between the fibers and causes a decrease in strength. In addition, since the lipophilic group is present on the fiber surface, the water absorption becomes poor.

い。As described above, the softening effect is exerted, but the strength and the water absorption are reduced accordingly, which is a serious defect for tissue paper and the like. Further, the decrease in strength causes an increase in paper powder, which is not preferable in practice.

向きである。On the other hand, a method of increasing the tactile sensation without using a chemical such as a softening agent is disclosed in Japanese Patent Laid-Open No. 2-29222. This is a method of mixing polyester fibers having a specific denier and fiber length with wood pulp. However, since polyester fibers do not have a hydrogen bonding ability, a vanider is required for mixing. The use of this binder results in some loss of flexibility. Further, since the fiber is hydrophobic, it is not suitable for tissue paper or the like that requires water absorption.

Although there are methods for improving flexibility as described above, all have various drawbacks as described above.

Was found. In other words, the crepe paper according to the present invention has a unique texture with a smooth surface and a silky feel, and is bulkier and stronger than conventional crepe paper. Especially when kenaf and abaca are mixed.

When applied, flexibility is improved, but strength is reduced.
Although strength can be increased by beating or the use of a paper strengthening agent, it is already known that the flexibility is deteriorated. That is, considering that the flexibility and the strength are contradictory to each other, it is extremely preferable and peculiar to improve the flexibility and the strength, and further the bulk.

いる。それらを詳細に検討した結果、繊維が同じ繊維長
レベルにある木材パルプに比べて細いことが判明した。The non-wood pulp according to the present invention has unique fiber morphology and fiber characteristics different from those of wood pulp. Detailed examination of them revealed that the fibers were thinner than wood pulp at the same fiber length level.

方法に関係なく、その材種に依存し、木材パルプでは繊
維長が長いほど繊維粗度は大きくなる傾向にある。Wood pulp is a commercially available product although it depends on the material type, and the fiber roughness (mg / 100 m) is softwood kraft pulp: 16 to 28,
Hardwood kraft pulp: 8-18. The fiber length (mm) is 2.8 to 4.0 for softwood kraft pulp and 0.7 to 1.5 for hardwood kraft pulp. The fiber roughness depends on the type of material regardless of the pulp manufacturing method, and the longer the fiber length of wood pulp, the higher the fiber roughness tends to be.

An important feature is less than 16 mg / 100 m. More specifically, when the fiber length is 2.5 mm or more, the fiber roughness is 16
It should be less than mg / 100m. Non-wood pulps that fall under this category include sun hemp, kenaf, sisal, and abaca. In this case, the fiber roughness is 16mg / 100m
If it is above, it will be the same level as the softwood kraft pulp and sufficient improvement in flexibility cannot be obtained. The above effect can be obtained by substituting a part or all of the softwood kraft pulp for these non-wood pulps and blending them.

Rather, a combination of a plurality of compounds is more preferable because the individual characteristics can be utilized and the synergistic effect can be exerted in the flexibility. And, the average fiber roughness of the whole papermaking raw material pulp which consists of non-wood pulp and wood pulp that meets the above conditions is 6 mg / 100 m or more, 16 mg / 1

Most preferably. If the above-mentioned non-wood pulp content is less than 5% by weight, satisfactory flexibility cannot be obtained, and if it exceeds 80% by weight, no further improvement in flexibility is observed.

Since the fibers are thinner than those of wood pulp, and the fibers themselves are supple and have excellent interfiber bonding ability, the synergistic effect of the two causes the crepe to be formed with a Yankee dryer, and then a fine crepe is formed to increase the rigidity. It is presumed that the crepe surface has a reduced roughness and the smoothness of the crepe surface has disappeared and the smoothness of the surface has improved, and that the crepe has strength and is soft to the touch and touch.
