Embodiment

[0110] The base paper and the chemical solution were manufactured under the following conditions, and the elongation test of the base paper (Test 1) and the performance comparison test of the tissue paper (Test 2) were carried out.

[0111] [base paper]

[0112] The pulp constituting the base paper is 50% NBKP and 50% LBKP. In addition, the base paper used before the lamination process has a basis weight of 13.5g / m per layer 2 , A base paper with a paper thickness of 150 μm and a crepe rate of 19% in a state where two layers are stacked.

[0113] [medicine solution]

[0114] The liquid medicine is prepared in such a way that the viscosity is 300mPa·s (40°C).

[0115] [Performance comparison of tissue paper]

[0116] For Examples 1 to 9 and Comparative Examples of the tissue paper of the present invention, a performance test and a sensory test were carried out. Table 1 shows the configurations of Examples 1 to 9 and Comparative Examples, and the results of performance eval...

Abstract

Disclosed is a tissue paper manufactured so as to be bulky without using bulking agents and the like and without increasing the number of manufacturing processes. Also disclosed is a method of manufacturing secondary whole rolls for a tissue paper product, which comprises (1) a laminating step of forming a laminated continuous sheet by laminating primary whole rolls fed from a plurality of primary whole rolls in a direction along which the rolls continue; (2) a chemical-solution applying step of applying chemical solution only to one of the top layers of the laminated continuous sheet or applying more chemical solution to one of the top layers than to the other top layer; (3) a joining step of forming linear joint portions that prevent layer separation on the laminated continuous sheet by nipping the laminated continuous sheet between a receiving roller and a driven roller. (4) a slitting step of slitting the laminated continuous sheet into sheets having a width or a several-fold width of a tissue paper product; and (5) a coiling step of forming a plurality of secondary whole rolls having the width or the several-fold width of the tissue paper product by coaxially coiling the slit laminated continuous sheets.

Description

technical field [0001] The present invention relates to a method of making secondary paper rolls for tissue paper products. Background technique [0002] In recent years, high-grade tissue papers that contain lotion to make skin feel soft have been used more and more. As a method of applying the chemical solution to the paper sheet (base paper), dipping; spraying; and coating by printing methods such as flexo and gravure can be used. However, for tissue paper, in order to improve its feeling of use, it is required to increase the bulkiness. However, the tissue paper coated with lotion chemical solution tends to stretch the wrinkles formed during papermaking due to the water absorption and moisture absorption of the paper. , so it is easy to cause a decrease in its bulkiness. Conventionally, the bulking treatment has been performed by internally adding a leavening agent composed of a cationic surfactant (Patent Document 2), water-absorbing starch (Patent Document 3), or emb...
