Detailed description of the invention
With reference to following drawing, be described in detail to implement embodiments of the present invention.
< embodiment 1 >
Fig. 1 represents the electron micrograph of the toilet paper body paper of the present embodiment.This electron micrograph, is taken by electric field radioactive scanning electron microscope (FE-SEM) (machine name: JSM-6301F: Jeol Ltd.'s system).Multiplying power is 30 times, and accelerating potential is 5kV, shooting angle be 90 degree (directly over).And sample is, the toilet paper body paper that cutting is got off is pasted on conductive tape, then by ion sputtering gold evaporation.
< is about the length > of the per unit area of fold
As can be seen from Figure 1, the toilet paper body paper of the present embodiment is formed with fold in the direction vertical with copy paper direction.Due to toilet paper body paper being formed with such fold, user can be improved by the elasticity experienced during finger touch toilet paper.Then, fold above-mentioned in the present embodiment, every 1cm
2the total length formed is at more than 200mm below 270mm.
Here, compared with before known toilet paper surface on the fold that formed can promote its elasticity.But, comprise the sanitary tissue that flexibility is good, every 1cm of existing toilet paper body paper
2the overall length of fold is 130mm ~ 190mm.To this, according to the wholwe-hearted research of inventor, if every 1cm of toilet paper body paper
2the length of fold in the scope of more than 200mm below 270mm, user, with during finger touch toilet paper, finger can touch more fold, fully it can thus be appreciated that can obtain significant elastic sensation.Therefore, the every 1cm in the present embodiment on toilet paper body paper is set
2the length of fold in the scope of more than 200mm below 270mm.Here, every 1cm
2the length of fold in the reason of more than 200mm be, every 1cm
2the length of fold be 220mm, or than its short about 10% when, also can obtain similar sufficient elastic sensation.And the feature of forming process from fold described later, often increase 1cm
2the length of fold, the height of fold has the tendency of reduction.Every 1cm
2the length of fold in the reason of below 270mm be, if every 1cm
2the length of fold larger than 270mm, then the height of fold starts to reduce and elastic sensation starts to go down.
In above-mentioned, the overall length of the fold of the per unit area on toilet paper body paper surface as shown in Figure 1, can derive by process as shown in Figure 2.That is, as shown in Fig. 2 (a), the fold detected on certain area is gone forward side by side row labels, with can the length of each fold of identification and direction.Extract the mark of the fold marked, it is as shown in Fig. 2 (b).Then, as shown in Fig. 2 (c), arrange the direction of the mark extracted, and the overall length of mark as accumulative in Fig. 2 (d).Then, with the area of this overall length marked divided by the shooting field shown in Fig. 2 (a).Now, arbitrary 10 places on shooting toilet paper body paper surface, carry out same mensuration, ask its mean value.This process, can be people's handwork, also can use preprogrammed automated system operation.
Further, in the present embodiment, the length of the fold of the density per unit volume of the fold on toilet paper body paper surface judges, and sees that Fig. 1 and Fig. 2 can understand, has deviation about the length of each fold and direction.Therefore, if when the number of the per unit area of the density toilet paper of fold judges, the deviation about the length of each fold can not be considered completely, and the density evaluating fold is exactly difficult.To this, in the evaluation on the present embodiment, the length of each fold is taken into account, can do to evaluate to the density of fold, precision is better, carries out evaluation become possibility to the density of fold.
< is about pivot weight >
Secondly, the pivot weight about the toilet paper body paper on the present embodiment is described.About pivot weight, be carry out measuring based on JISP8124 " assay method of paper or paperboard-pivot weight ".The pivot weight of existing toilet paper body paper, general sanitary paper is 10g/m
2~ 13g/m
2, the sanitary tissue that flexibility is good is 14g/m
2~ 16g/m
2the situation of left and right is in the majority.To this, the wholwe-hearted research according to inventor can be learnt, supposes that pivot weight is at 13g/m
2above 18g/m
2following toilet paper body paper, by with above-mentioned every 1cm
2overall length combine at the fold of more than 200mm below 270mm, user can obtain significant elastic sensation.
In fold formation process described later, consider that the same terms forms fold, the situation of the fold that height of formation is large by making toilet paper body paper thicker when copy paper.Further, in above-mentioned, the pivot weight of toilet paper body paper is at 13g/m
2above reason is, pivot weight is 15.8g/m
2time, or pivot weight than its few about 20% time, user can obtain significant elastic sensation.In above-mentioned, the upper limit of the pivot weight of toilet paper body paper is 18g/m
2reason be that pivot weight is larger, have to change pulping process (conditions of beating), can there is extreme variation in the feel of body paper, more precisely form similar paper towel.
< is about thickness G reatT.GreaT.GT
Secondly, the thickness of the toilet paper body paper in the present embodiment is explained.About existing toilet paper body paper, even if there is the good sanitary tissue of flexibility, 20 stacked add after height be about 3.0mm ~ 4.8mm.To this, the toilet paper body paper manufactured in the present embodiment, 20 stacked add after height at more than 5.0mm below 6.5mm.Therefore, compared with toilet paper body paper before, comparatively significant elastic sensation can be obtained.
Further, in the present embodiment, limit the overall length of the per unit area of the above-mentioned fold of toilet paper body paper, pivot weight and 20 stacked add after height.That is, the height in the present embodiment after 20 layers of toilet paper body paper superposition, by selecting the pivot weight of toilet paper body paper rightly, and the height of the density and fold that control fold rightly in fold formation process described later is achieved.
Here, the assay method of the height after 20 layers of toilet paper body paper superposition in the present embodiment is explained.In the present embodiment, use dial thickness gauge 547-321 type (Mitutoyo system) as sensing equipment.It is metal for measuring mensuration used, and its diameter is
heavy burden during mensuration is 1.5N.And this is measured, get the average value of 10 mensuration as measurement result.
And, the generally thickness of toilet paper, large multiplex JISP8118 " test method of paper or paperboard-thickness and density " judges, when only measuring thickness by this method, sample evaluated error when number is few is large, the number increasing sample is thinning due to what conduct oneself with dignity and make thickness relative, and these inappropriate situations happen occasionally.
To this, number when inventor measures the thickness of toilet paper body paper and the relation of thickness, shown in Fig. 3, number is before reaching about 20, and it is thin for the Thickness Ratio revealed relative to the original thickness table proportional with number, and number is when reaching the regulation number more than 20, if increase number again, find, due to deadweight, to make relative thinning of thickness, the phenomenon of the increase of thickness not to scale (NTS).Here, when number is less than 20, thickness table reveals thinning phenomenon, and consideration is measuring instrument actuating pressure on the toilet paper body paper that number is few, the reason that fold strikes the beam.To this inventor, be conceived to a lower limit number, the impact of the impact that this lower limit makes fold strike the beam, the deadweight of toilet paper body paper can not reflect in measurement result, and by 20 toilet paper body paper superpositions also detect thickness.Accordingly, because the number of sample can drop to evaluated error minimum less, also can get rid of the impact of sample deadweight simultaneously, thus can with the thickness of good precision measure toilet paper body paper.
As above, according to the present embodiment, owing to selecting and controlling the pivot weight of toilet paper body paper, the overall length of the fold of per unit area and the height of fold rightly, after 20 toilet paper body paper superpositions, fully thick height can be reached.Accordingly, time user touches toilet paper, comparatively significant elastic sensation can be obtained.
< is about the addition > of softening agent
Secondly, the amount of softening agent of the toilet paper body paper comprising the present embodiment is explained.The toilet paper of the present embodiment, not outer interpolation is apt to the water-based of NMF, softening agent etc. or the liquid of oiliness of surface flatness, but under the state of the paper pulp suspension of liquid state in add the softening agent of imidazo-containing compounds (Imidazoliumcompounds) and fatty acid ester emulsion (Fattyacidesteremulsion).Then, comprise the sanitary tissue that flexibility is good, containing the softening agent of 0.01 % by weight ~ 0.05 about % by weight in existing toilet paper body paper.To this, in the toilet paper body paper of the present embodiment, containing softening agent more than 0.2 % by weight, less than 0.3 % by weight.
Here, the toilet paper body paper of the present embodiment, as mentioned above, forms every 1cm
2, the highdensity fold that more than 200mm below 270mm is such.Even if but under these conditions, if the summit of fold presents the shape of point, be difficult to obtain smooth sense of touch time user touches with hand.To this, according to the research of inventor, with every 1cm
2form the fold of more than 200mm below 270mm, and make pivot weight be 13g/m
2above 18g/m
2during following scope, because it contains more than 0.2 % by weight, the imidazo-containing compounds of less than 0.3 % by weight and the softening agent of fatty acid ester emulsion, can obtain sense of touch smooth significantly time user touches with hand.In fact, the situation containing the softening agent of 0.25 % by weight, and relative to the amount of the softening agent of 0.25 % by weight have ± increase and decrease of about 20% when can both obtain sense of touch smooth significantly.
Infer that this is because it contains more than 0.2 % by weight, the imidazo-containing compounds of less than 0.3 % by weight and the softening agent of fatty acid ester emulsion, the shape on the summit of the fold of setting high density high altitude is that circle becomes possibility, in addition, when user touches toilet paper body paper with hand, the probability directly touching the softening agent of the surface existence being dispersed in fold with hand can increase.From the above, the toilet paper body paper of the present embodiment is allowed to contain more than 0.2 % by weight, the imidazo-containing compounds of less than 0.3 % by weight and the softening agent of fatty acid ester emulsion.Accordingly, from the toilet paper body paper of the present embodiment, except the significant elastic sensation of acquisition, also may obtain significant surperficial slip.And, softening agent on the present embodiment, except imidazolium compounds 75 ~ 85 % by weight, is combined with fatty acid ester emulsion 10 ~ 15 % by weight and polyethylene glycol 0 ~ 5 % by weight in addition, as long as but imidazo-containing compounds and fatty acid ester emulsion, then the composition of softening agent is not limited thereto.
< is about hot strength >
Secondly, the hot strength of the toilet paper body paper of the present embodiment is explained.The mensuration of hot strength itself is undertaken by JISP8113 " test method-of paper or paperboard-tensile properties 2: constant speed upholds method ".
General in toilet paper body paper, if the screenings degree of paper pulp fiber reduces, hot strength has the tendency of step-down.Consider be due to, if paper pulp fiber screenings degree reduce, during stretching, the fiber of paper pulp becomes easy separation.And consider that the resistance of paper can die down if reduce the screenings degree of paper pulp fiber simultaneously.Therefore, for the toilet paper body paper on the present embodiment, the geometric average of the hot strength in MD direction, CD direction is more than 90gf/25mm below 170gf/25mm (being preferably more than 100gf/25mm below 140gf/25mm).And more than MD/CD=1.7 less than 3.0.The hot strength of toilet paper body paper, when this scope, can make the resistance of body paper die down, and enables user experience significant flexibility.
The flexibility > that < experiences about user
Here, the flexibility generally in order to allow user experience paper, 3 principal elements affecting flexibility are " weakness " of (A) elastic sensation, (B) surperficial slip, (C) resistance.
According to the toilet paper body paper on the present embodiment, due to every 1cm
2the length of fold is at more than 200mm below 270mm, and pivot weight is at 13g/m
2above 18g/m
2below, the thickness of 20 stacked added-time is at more than 5mm below 6.5mm in addition, can obtain very large elastic sensation.And containing more than 0.2 % by weight due to it, the imidazo-containing compounds of less than 0.3 % by weight and the softening agent of fatty acid ester emulsion achieve significant surperficial slip.In addition, for hot strength, the geometric average in MD direction, CD direction is more than 90gf/25mm below 170gf/25mm (being preferably more than 100gf/25mm below 140gf/25mm), and set more than MD/CD=1.7 less than 3.0 due to more weak, therefore, the " weakness " of resistance is adequately achieved.So, in the toilet paper body paper of the present embodiment, make whole principal elements meet the " weakness " of above-mentioned (A) elastic sensation, (B) surperficial slip, (C) resistance, user can experience significant flexibility.
The evaluation > of < in apparent density
And in the present invention, about the flexibility of toilet paper body paper, as shown in quantity formula (1), with 20 superposition body paper thickness divided by pivot weight value (below it being called apparent density) evaluate also be fine.
Thickness (mm)/pivot weight (g/m
2)=apparent density (× 10
-3m
3/ g) (1)
The concept of this apparent density judges from dimension, because this amount is equivalent to the amount of the paper of paper pulp how many apparent densitys of predetermined weight, can expects that this amount is larger, more have flexibility.Therefore, by this apparent density (× 10
-3m
3/ g)=thickness (mm)/pivot weight (g/m
2) flexibility of evaluating toilet paper body paper is also fine.In the present embodiment, the scope of apparent density is 0.30 × 10
-3m
3/ more than g 0.40 × 10
-3m
3/ below g is also fine.This scope, as mentioned above, pivot weight is at 13g/m
2above 18g/m
2below, the thickness of 20 stacked added-time is in more than 5mm below 6.5mm situation, and the scope of apparent density is then 0.27 × 10
-3m
3/ more than g 0.50 × 10
-3m
3/ below g, particularly, 0.35 × 10
-3m
3when in the scope of/g and ± 20%, good flexibility can be obtained.
