Tissue paper and method for manufacturing tissue paper

Abstract

Tissue paper containing a softener, and having a dry tensile strength of 200 cN/25 mm or greater and 400 cN/25 mm or less in a longitudinal direction, a rate of elongation of 5% or higher and 25% or lower in the longitudinal direction, and a proportional limit tensile stress of 160 cN or greater and 250 cN or less in the longitudinal direction is provided.

1 . Tissue paper, comprising:
 a softener,   wherein the tissue paper has a dry tensile strength of 200 cN/25 mm or greater and 400 cN/25 mm or less in a longitudinal direction,   the tissue paper has a rate of elongation of 5% or higher and 25% or lower in the longitudinal direction, and   the tissue paper has a proportional limit tensile stress of 160 cN or greater and 250 cN or less in the longitudinal direction.   
     
     
         2 . The tissue paper according to  claim 1 ,
 wherein the softener contains an oil content by 0.1% by mass or greater and 0.25% by mass or less in the softener, the oil content being extractable with diethyl ether.   
     
     
         3 . The tissue paper according to  claim 1 ,
 wherein the tissue paper has a proportional limit displacement rate of 40% or higher.   
     
     
         4 . The tissue paper according to  claim 1 ,
 wherein the tissue paper has a permanent displacement rate of 21% or higher at 150 cN.   
     
     
         5 . The tissue paper according to  claim 1 ,
 wherein the tissue paper has a spherical compression work of 300 mJ or lower.   
     
     
         6 . The tissue paper according to  claim 1 ,
 wherein the tissue paper has an arithmetic mean height of 3 μm or greater and 7 μm or less.   
     
     
         7 . A method for manufacturing the tissue paper of  claim 1 , the method comprising:
 performing papermaking using a pulp slurry to which the softener is added, to make a wet paper web;   drying the wet paper web using a yankee dryer, to make dry paper; and   peeling the dry paper from the yankee dryer using a creping doctor,   wherein a glue is applied on a surface of the yankee dryer by 0.5 mg/m 2  or greater and 3.5 mg/m 2  or less.   
     
     
         8 . The method for manufacturing the tissue paper according to  claim 7 ,
 wherein the glue contains a polyamide-based resin.
