Detailed description of the invention
Fig. 1 is the perspective view of the roll toilet paper of present embodiment.
Fig. 2 is the figure for showing the measurement device of MMD.
Specific embodiment
The toilet paper of present embodiment for example formed as long ribbon shape, defend by the reel particularly suitable for the web-like on paper tube The form of raw paper.In the case where the form of roll toilet paper is made, about its size etc., preferably wide L1 be 101~106mm, Diameter L2 is 100~120mm, spooling length (overall length of toilet paper) is 18~70m, paper tube internal diameter L3 is 35~50mm.For When the size, the paper frame of common roll toilet paper can be utilized, in the cleaning purpose after the excretion in closestool space easily In use, also, the length of toilet paper is other than being sufficient length for the cleaning purpose after above-mentioned excretion, as thin page Paper like that general use when be also sufficient length.
Toilet paper of the invention is the uncoated toilet paper of moisturizer for not adding moisturizer come outside by coating etc. substantially.Make For additive moisturizer can example go out the polyalcohols such as glycerol, diglycerol, propylene glycol, 1,3 butylene glycol, polyethylene glycol, sorbose The polyalcohol of the carbohydrates such as alcohol, glucose, xylitol, maltose, maltitol, mannitol, trehalose etc.But it is if above-mentioned Ingredient can only bring the influence for being unworthy the referred to as degree of moisture retention toilet paper containing degree, then do not refuse containing it is above-mentioned at Point.Intensity is difficult to ensure if being coated with moisturizer.However, it is possible to add the flexibility of the interior decision body paper added in copy paper itself Softening agent, soft moisturizer with paper power.As softening agent, fatty acid ester based compound, fatty acyl amine system chemical combination can be enumerated Object.Wherein, fatty acid amide based compound has the effect of coated fiber surface.
The toilet paper of present embodiment is 3 layers or 4 layers.That is, being overlapped into one group for 3 or being overlapped into one group for 4. By multilayered structure as forming 3 layers or 4 layers, although the thickness of each layer is thinned, whole thickness of paper can also be thickened, especially It can be improved the skin sense of touch of " flexibility " and " fluffy sense " etc and not easily damaged.It should be noted that if being 2 layers, then It is not easy to embody thickness sense, when being used for the cleaning of article as universal product, journey is easily experienced in terms of not damageability It spends weaker.In addition, even if each layer is then thinned, being also not easy to experience as a whole when carrying out skin cleaning if 5 layers or more Flexibility, it is difficult to embody skin sense of touch Optimality, and be easy breakage when each layer is excessively thin.In addition, especially at 5 layers or more In the case where, rigidity sense can be experienced strongly when assigning embossing.The toilet paper of present embodiment in 3 layers or 4 layers appoint There is characteristic below, so that damageability and skin sense of touch be not excellent when one.
The toilet paper of present embodiment for 3 layers or 4 layers and following base weights, thickness of paper, longitudinal dry tensile strength and In the case that laterally wet tensile strength is relative to laterally the ratio between dry tensile strength all obtains satisfaction, not damageability and flesh Skin sense of touch is excellent.
Every 1 layer of the base weight of the toilet paper of the present embodiment is 14.9g/m2The above 16.2g/m2Below.If 1 layer of base weight For that within the scope of this, then at above-mentioned 3 or 4 layers, can have adequately the Optimality of not damageability and skin sense of touch, and hold It easily embodies water-disintegrable.
The toilet paper of present embodiment is 297 μm or more 435 μm or less as 3 layers or 4 layers of whole thickness of paper.If thickness of paper For within the scope of this, then when being 3 or 4 layers of above-mentioned base weight, it can be ensured that adequately not damageability, and then skin can be made to touch Sense, particularly flexibility are good.
It should be noted that base weight of the invention is the value of the base weight measuring method based on JIS P 8124 (1998).Paper Thickness is after test film is carried out abundant damping under conditions of 8111 (1998) P JIS, to be surveyed under the same conditions using dial type The value that thick instrument (thickness tester) " PEACOCK G type " (the rugged production of tail is made) measurement obtains.Specifically, confirmation plunger with There is no dirt, dust etc. between measurement platform, plunger dropped on measurement platform, keep the scale of above-mentioned dial type calibrator mobile and Next zero lifts plunger and coupons is placed on measurement platform, slowly falls plunger, read table number (gauge) at this time. Notice that the terminal (circular flat of diameter 10mm) for the plunger for manufacturing metal is vertically contacted with paper plane in measurement.It needs It is noted that the load when thickness of paper measures is about 70gf.
The dry tensile strength in the longitudinal direction of the toilet paper of present embodiment is 451cN/25mm or more 1001cN/25mm or less. Compared with the wiping special product after excretion, which is very high value.Firstly, the toilet paper of present embodiment is logical Cross with drying tensile strength high in this way and in general use very not cracky.In addition, longitudinal dry tensile strength is high When, it is particularly easy to embody the smoothness of skin sense of touch.
In the toilet paper of present embodiment, laterally wet tensile strength is relative to laterally the ratio between dry tensile strength 0.09 or more.This is above the value of existing product.Herein, especially " laterally dry tensile strength " is considered not being to " soft Property ", the other of " fluffy sense " etc aesthetic have an impact but have an impact to the entirety of " skin sense of touch " is aesthetic.It was found that For measured not with the specific evaluation criteria of " flexibility ", " fluffy sense " etc and with after sample contact free When " skin sense of touch " this overall merit benchmark evaluates tissue paper, it is somebody's turn to do the evaluation of " skin sense of touch " and " laterally drying is strong Degree " has certain correlation.Laterally dry tensile strength is preferably 180cN/25mm or more 395cN/25mm or less.Another party Face, laterally wet paper power has the tendency of the most weak value in the index for showing the intensity for indicating paper.Laterally wet paper power is high for this In the case where, the strong sense that is wiped under moisture state and trusting when using cleaning after so-called warm water cleaning type pedestal toilet Feel excellent.In the roll toilet paper of present embodiment, laterally wet tensile strength relative to laterally the ratio between dry tensile strength height, It is 0.09 or more.That is, the balancing good of skin sense of touch and strong sense.Herein, from need its after the excretion in closestool space In the actual use such as cleaning purpose will not it is damaged, have that from the aspect of trusting sense, laterally wet tensile strength is excellent in wiping It is selected as 25cN/25mm or more 40cN/25mm or less.Above-mentioned wet tensile strength/transverse direction drying tensile strength in this range Ratio be 0.09 or more when, for ensure using when flexibility be highly preferred.
It should be noted that the longitudinal direction of paper is also referred to as the direction MD, flow direction when being copy paper.The transverse direction of paper is also claimed It is the direction orthogonal with flow direction (direction MD) when copy paper for the direction CD.In addition, drying tensile strength of the invention is base Obtained value is measured in JIS P 8113 (2006), is measured as follows.Test film use is longitudinally, laterally being cut into width The test film of 25mm (± 0.5mm) × long 150mm or so.Test film is directly measured using multilayer.Testing machine uses The load cell cupping machine TG-200N of Minebea Co., Ltd. manufacture and comparable it is equal to instrument with its.It needs to illustrate , between setting clamp distance be 100mm, tensile speed 100mm/min.Measurement is carried out using following processes: by test film Both ends be fastened on the collet of testing machine, along the vertical direction to the scraps of paper apply tensile load, read paper fracture when indicated value (digital value).Longitudinally, laterally preparing equal 5 groups of sample respectively, it is each respectively to carry out 5 measurements, by the average value of its measured value Drying tensile strength as all directions.For product, multi-disc overlapping is measured according to the number of plies of product by dry tensile strength. For body paper, multi-disc overlapping is also measured according to the number of plies of product by dry tensile strength.
In addition, wet tensile strength is to measure obtained value based on JIS P 8135 (1998), it is measured as follows.Test Piece is used in the test film for being longitudinally, laterally cut into wide 25mm (± 0.5mm) × long 150mm or so.It is multilayer in tissue paper In the case where, directly measure multilayer.The load cell cupping machine TG- that testing machine is manufactured using Minebea Co., Ltd. 200N and comparable it is equal to instrument with its.It should be noted that between setting clamp distance be 100mm, tensile speed 50mm/ min.Test film, which is used, carries out the test film after curing (curing) 10 minutes using 105 DEG C of drying machine.Utilize following processes It is measured: the both ends of test film is fastened on the collet of testing machine, later using aqueous tack brush with the width of about 10mm Degree horizontally assigns water to the central portion of test film, applies tensile load to the scraps of paper along the vertical direction immediately after, and it is disconnected to read paper Indicated value (digital value) when splitting.Longitudinally, laterally preparing equal 5 groups of sample respectively, it is each respectively to carry out 5 measurements, it is surveyed Wet tensile strength of the average value of definite value as all directions.In wet tensile strength, all in accordance with product the number of plies by multi-disc Overlapping is to measure wet tensile strength.
