2Through reducing basic weight, can weaken the deflection of paper, make paper be rich in enough flexibilities.But,, then cause the reduction of intensity etc. if said basic weight is low excessively.In addition, measure basic weight based on JIS P 8124.
The pliability of goods is preferably 0.5g～1.0g, is preferably 0.6g～0.8g especially.If pliability less than 0.5g, then is rich in flexibility, but the problem that the deflection of paper weakens has appearred, if pliability greater than 1.0g, then flexibility weakens, the paper hardening.Pliability is meant; Based on " hand feel measurement (Ha Application De Le オ メ one タ) the E method " among the JIS L 1096; The goods that will be cut into long 10cm * wide 10cm by terminal (for example; If 2 goods of sheet layer by layer, just directly use 2 sheets layer by layer) Resistance Value (mean values of goods vertical and horizontal) when being pressed in the slit of wide 5mm.
In addition, the soup lotion content, 1 of the above-mentioned per unit volume thin slice that relates to the soup lotion is the basic weight of sheet layer by layer, and a series of content of pliability also is applicable to the lotion of the antivirotic of stating after containing.
Soup lotion among the present invention does not have special qualification, the soup lotion of mainly giving an example out and focusing on following aspect: improve skin contact (feel), improve moisture retention, make paper pulp fiber gentle to the stimulation of skin, or improve moist feeling.
For example, as the moisture retention soup, can enumerate through use and contain the soup that the material of NMF forms, said NMF is at least a in the following NMF: polysiloxanes such as silicone oil, silicone powder; Glycerine, diglycerol, propane diols, 1, polyalcohols such as 3-butanediol, polyethylene glycol; Carbohydrates such as D-sorbite, glucose, xylitol, maltose, maltitol, mannitol, trehalose; Glycol series solvent and derivative thereof.
And, also can use higher alcohols such as cetanol, stearyl alcohol, oleyl alcohol; Atoleine etc.
