Description
Technical field
The present invention relates to be used to be impregnated with the flat substrates of the wet sheet of liquid.
Background technology
The wet sheet that forms if multi-disc made the flat substrates steeping liq is overlapping and be kept in the container, because the influence of gravity, liquid just has the tendency that moves downwards, sometimes the content of liquid be every all different.Be cause thus, when sheet was wet in use, the performance of liquid just can not be brought into play fully.In addition, because the content of liquid is few, cause easily that also use feeling descends.And, accumulate liquid at container bottom sometimes, cause liquid to be wasted.For example, when wet sheet was used sheet as the makeup removing of making up, last slice poor, the following sheet of washing performance in the superimposed sheets was clamminess and makes the sensation variation.
Even, be 15～200g/m and propose the applying unit area weight for many wet sheets is overlapping and preserve and also can cause flowing of liquid
2The scheme (consulting the clear 63-54137 communique of Japanese Patent Application Laid-Open) of melt spraying non-woven fabrics of vistanex.This melt spraying non-woven fabrics is characterised in that at least 65% of hole is that size is the hole of 20～60 μ m.
In addition, the applicant has formerly proposed following scheme, a kind of wet sheet base material, wherein, at least 1 synusia contain hydrophilic fibre, overlapping identical type or different types of, give 2 layers of concaveconvex shape or more multi-layered concavo-convex, have bonded zone between adjacent this concavo-convex by embossing processing, like this should concavo-convex partly pressing or fusion and form sandwich construction, give concaveconvex shape (consulting Japanese patent application 2000-290899 communique) by above-mentioned embossing processing.
But, in the technology of the clear 63-54137 communique of Japanese Patent Application Laid-Open record, because vistanex is hydrophobic, institute is so that be that the melt spraying non-woven fabrics of raw material is when flooding waterborne liquid with the vistanex, this nonwoven must be carried out hydrophilicity-imparting treatment, make trouble.In addition, although with create conditions relevantly, the common feel of melt spraying non-woven fabrics is bad, if especially use it for wiping skin, feeling of wiping is bad.
According to the disclosed technology of Japanese Patent Application Laid-Open 2000-290899 communique, even, also be difficult to cause flowing of liquid with many overlapping and preservations of wet sheet.Be difficult to the wet sheet base material that causes that liquid moves more but require to have.
Summary of the invention
The invention provides a kind of sheet basis material for wet sheet, it is by possessing 1 pair of skin and constitute at this fibre plate to the 3-tier architecture of the internal layer between the skin, and is impregnated with liquid and is used for the health wiping.Average distance between each outer field fiber all is 3～35 μ m, and the average distance between the fiber of internal layer is 1～25 μ m.And the average distance between each outer field fiber is all bigger than the average distance between the fiber of internal layer.
The specific embodiment
Below, the present invention will be described based on its embodiment preferred.Flat substrates of the present invention, steeping liq and form wet sheet is drying regime before liquid infiltration.Flat substrates is made of the fibre plate of the 3-tier architecture that contains fibrous material.As each layer, can use various weaving cloth, nonwoven, woven cloth, their complex etc.If consider the maintenance performance and the manufacturing expense of liquid, preferably use various nonwoven.
In the flat substrates of the present invention, the average distance between each outer field fiber is all bigger than the average distance between the fiber of internal layer.Thus, make the capillary force generation in internal layer and the skin poor.Consequently, in the stacked preservation of wet sheet, be difficult to cause moving of liquid, and, keep good hand feeling.
From the stacked preservation of wet sheet, be difficult to cause that the viewpoint that liquid moves sets out, the average distance between each outer field fiber is 3～35 μ m, 3.5～33 μ m preferably, being more preferably becomes 4～31 μ m.Average distance between the fiber is during less than 3 μ m, and the difference of the average distance between the average distance between the outer field fiber and the fiber of internal layer is just insufficient.When the average distance between the fiber surpasses 35 μ m, cause moving of liquid easily.Average distance between the fiber in each skin can be identical, also can be different.Average distance between the fiber is calculated from following formula.Average distance between the fiber:
In the formula, w representation unit area weight (g/m
2), L represents thickness (cm)
α represents the composition (wt%) of i fiber, Dt
iThe fibre diameter (dtex) of representing i fiber,
Δ is represented the distance (μ m) between the average center, and Fd represents fiber diameter (μ m).
In order to realize being difficult to causing the purpose that moves of liquid, in the present invention, except stipulating between the above-mentioned outer average fiber that the distance, the average distance between the fiber of internal layer is 1～25 μ m, is preferably 2～23 μ m.Average distance between the outer field fiber is bigger than the average distance between the fiber of internal layer, particularly, the viewpoint that liquid when being difficult to cause stacked preservation of wet sheet moves, average distance between the preferred outer field fiber be between the fiber of internal layer average distance 101～1000%, be preferably 120～750% especially.
The average distance between the fiber of above-mentioned ectonexine, if the absolute value of the difference of the apparent density of each outer and internal layer 0～0.32g/cm preferably
3, be more preferably 0～0.12g/cm
3The time, in the stacked preservation of wet sheet, moving of liquid just becomes difficult more.At this moment, each outer field apparent density can be bigger than the apparent density of internal layer, perhaps on the contrary can for, the apparent density of internal layer is bigger than each outer field apparent density.
Apparent density is measured like this by following.To carry out stacked each layer before integrated and be cut into, measure its weight, it will be converted into 1m according to the size of 100mm * 100mm
2Weight and obtain weight per unit area.In addition, with 20gf/cm
2Heavy burden measure down the thickness of each layer that is cut into.Remove the weight per unit area that obtains with thickness, thus the apparent density of obtaining.
The difference of the apparent density of outer and internal layer as mentioned above, the apparent density of each layer is preferably as follows.About skin, its apparent density is 0.04～0.50g/cm preferably
3, 0.05～0.21g/cm especially preferably
3At this moment, about two skins, its apparent density can be identical, also can be different.On the other hand, about internal layer, its apparent density is 0.05～0.40g/cm preferably
3, 0.08～0.18g/cm especially preferably
3Particularly littler than internal layer apparent density by each outer field apparent density is set at, can when suppress flowing of liquid, internal layer make the flat substrates of bulk, soft soft feel, thereby be preferred.
In order to improve the liquid diffusivity of flat substrates of the present invention, preferred orientation is 2.5～4.0.Be oriented to more than or equal to 2.5 o'clock, the diffusivity of liquid takes a turn for the better, and orientation is smaller or equal to 4.0 o'clock, makes and becomes easy.Here so-called orientation refers to molecularly oriented, can be measured by the MOA-2001A that for example prince's instrumentation machine Co., Ltd. produces.
Flat substrates of the present invention is at the 5g/cm that floods 400% liquid and add 10 seconds
2The state of loading under, the slowly-releasing rate of liquid is more than or equal to 280%, because the liquid that can make abundant amount from the flat substrates slowly-releasing, from obtaining to improve the aspect of scrubbing performance, is preferred therefore.The liquid that goes out from the sheet material slowly-releasing, the dirt of dissolving skin and cosmetic dirt and remove from skin after, sucked back by flat substrates, may remove the dirt of skin thus.
The condition determination of slowly-releasing rate is set at " adds the 5g/cm in 10 seconds
2Load state " reason be condition basically identical when depending on this loading and time and people's wiping skin.The slowly-releasing rate is measured with following method.Mensuration is adjusted to the weight A of the flat substrates of 50mm * 200mm size, makes it to flood the liquid of 4 times of weight that are equivalent to weight A.Weight behind the dipping is counted B.Then, with kimtowel (trade name; The production of Network レ シ ア Co., Ltd.) flat substrates of the whole steeping liqs of parcel.Then, wrapping up above the flat substrates, placing the acrylate plate of 100mm * 100mm, carrying the counterweight that conforms to meter 500g loading thereon with kimtowel.After removing counterweight and acrylate plate after 10 seconds, measure the weight C of flat substrates, calculate the slowly-releasing rate by following formula.
Slowly-releasing rate (%)=(B-C)/A * 100
As previously mentioned, outer and internal layer all preferably is made of nonwoven.From suppressing the aspect consideration that liquid moves downwards, so preferred internal layer contains the hydrophobic fibre more than or equal to 30 weight %.Internal layer especially preferably is made of 100% hydrophobic fibre.Internal layer preferably intersects formations such as nonwoven, spunlaced (spun lace) nonwoven by melt spraying non-woven fabrics, spun-bonded non-woven fabrics, longitude and latitude.Intersect nonwoven as longitude and latitude, preferred MILIFE (trade name; Having only vertically or nonwoven in length and breadth of new day stone プ ラ ス ト Co., Ltd. (Nisseki Plasto Co. Ltd) producing).If internal layer constitutes with melt spraying non-woven fabrics, then this internal layer is because the effect of bringing into play as the insulating course that hinders liquid to move downwards increases, so preferred especially.Because melt spraying non-woven fabrics is made of superfine fiber,, keep the ability height of liquid by capillary force so distance is short between the average fiber.
Hinder the effect that liquid moves downwards, also relevant with the weight per unit area of melt spraying non-woven fabrics.Weight per unit area is low excessively, just can not keep liquid fully, and liquid just has the tendency that moves easily downwards.On the other hand, weight per unit area is too high, though keep the ability of liquid abundant, the use feeling of wet sheet has the tendency of decline.Flat substrates of the present invention is because be to be used for the wet sheet that the health wiping is used, so the requiring on the characteristic of commodity, usability is important project.Consider these, as the weight per unit area of the operable melt spraying non-woven fabrics of internal layer 1～60g/m preferably
2, 2～40g/m especially preferably
2
From the relation of the value of the value of above-mentioned weight per unit area and foregoing apparent density, can be used as the thickness of the melt spraying non-woven fabrics that internal layer uses, preferably 0.02～0.30mm, especially preferably 0.03～0.25mm.
As the fiber that constitutes the melt spraying non-woven fabrics that can be used as internal layer, can use the fiber of various thermoplastic resins.When fiber was hydrophobicity originally, preferably carries out various hydrophilicity-imparting treatment and become hydrophily.Melt spraying non-woven fabrics then can supplementary features because fiber is superfine.Can be used for melt spraying non-woven fabrics of the present invention, its fiber number is 0.001～0.1dtex, and particularly 0.008～0.08dtex is preferred, and this is because easily the average distance between the fiber of internal layer is controlled in the scope of narrating previously.
On the other hand, as constituting outer field nonwoven, can use for example various nonwoven of wet type aspunlacednonwovenfa,ric, dry type aspunlacednonwovenfa,ric, air-flow nonwoven, hot-wind nonwoven cloth, melt spraying non-woven fabrics, spun-bonded non-woven fabrics etc.In these nonwoven, from the saturating machine of liquid, keep viewpoints such as performance, feel, preferably use wet type aspunlacednonwovenfa,ric or dry type aspunlacednonwovenfa,ric etc.
When constituting each skin by aspunlacednonwovenfa,ric, in order to control the distance between its fiber, suitably control the kind of employed fiber, the hydraulic pressure when perhaps suitably controlling current crossed fiber net is just passable.If for example set hydraulic pressure high, then the distance between the fiber just has the tendency that diminishes.On the contrary, if set hydraulic pressure low, then the distance between the fiber just has the tendency that becomes big.In order to obtain having the skin of the average distance between the foregoing fiber, to decide according to the weight per unit area of fabric, the hydraulic pressure that current interweave is preferably 3～35Mpa, especially preferably 10～30MPa generally.Current interweave also can be divided into repeatedly according to purpose and carry out.Hydraulic pressure can also can pressurize from the two sides from the surface or the inside pressurization of fabric.In addition, hydraulic pressure can be adjusted in any stage, also can at this moment maximum hydraulic pressure be adjusted into above-mentioned hydraulic pressure.In addition, as required, also can interweave the back with the backer roll pressurization by current, also can after current interweave, carry out drying, after this pressurize.As the condition of pressurization, preferred line pressure is 1～60kg/cm, is more preferably 10～50kg/cm.
Constitute in each outer field aspunlacednonwovenfa,ric, preferably contain,, preferably contain hydrophilic fibre again more than or equal to 75 weight % more preferably greater than the hydrophilic fibre that equals 65 weight % more than or equal to 55 weight %.Certainly, skin also can be made of 100% hydrophilic fibre.In each skin, the cooperation of fiber can be identical also can be different.
As hydrophilic fibre, can use the fiber of original possess hydrophilic property or be not hydrophilic originally, but become these two kinds of hydrophilic fibers by hydrophilicity-imparting treatment.As the fiber of original possess hydrophilic property, can list for example natural fiber such as cotton and paper pulp, artificial silk, acrylate, cuprammonium rayon, テ Application セ Le (TENCEL), リ ヨ セ Le (LYOCEL) etc.As not being hydrophilic originally but becoming hydrophilic fiber by hydrophilicity-imparting treatment, for example can list, the fiber that is made of hydrophobic resins such as polyolefin resin and polyester resins has been applied the fiber of hydrophilicity-imparting treatment.In these fibers, from the good degree of feel, preferred cotton, artificial silk, acrylate, テ Application セ Le, the リ ヨ セ Le of using especially preferably uses cotton.Hydrophilic fibre can use a kind, be used in combination two or more.
As hydrophilic fibre, except above-mentioned cotton fiber,, also can cooperate latent crimp fiber in order to improve bulkiness.As latent crimp fiber, can use fiber with the fibroplastic core sheath structure that constitutes by polyethylene, polypropylene, polyester and core shift structure, parallel type structure.May improve outer field various characteristics thus.
Can be used for outer field hydrophilic fibre, its fiber number is 0.2～5.5dtex preferably, is more preferably 0.8～4.4dtex, again 1.3～3.3dtex preferably.If use the fiber of this scope fiber number, the distance of suitably controlling between the foregoing fiber just becomes easy.When using two or more hydrophilic fibres, the fiber number of preferred at least a kind of hydrophilic fibre is in above-mentioned scope.The fiber number of preferred all hydrophilic fibres is in above-mentioned scope especially.
Use is during as natural fiber cotton, because cross sectional shape is not positive circle, so be 3 when calculating with the aspect ratio in cross section, preferably falls into above-mentioned rugosity scope.If use the fiber of the fibre diameter of this scope, the distance of suitably controlling between the foregoing fiber just becomes easy.When using two or more hydrophilic fibres, the rugosity of preferred at least a kind of hydrophilic fibre is in above-mentioned scope.The rugosity of more preferably all hydrophilic fibres becomes above-mentioned scope.
Use when cotton as hydrophilic fibre, grand (Micronaire) fiber number (μ g/in) of mark is 2.5～6.0 μ g/in preferably, but sensation also becomes good during 3.1～4.4 μ g/in, thereby are preferred.
Fibre length to hydrophilic fibre has no particular limits, but sensation and productivity ratio when using, preferably 5～70mm.
From sensation and pliability, for each skin, its weight per unit area is 10～100g/m preferably
2, 20～50g/m especially preferably
2For each outer field thickness, from the relation of above-mentioned weight per unit area value and foregoing apparent density value, preferably 0.05～0.60mm, especially preferably 0.10～0.50mm.Each outer field weight per unit area and thickness can be identical, also can be different.
For each skin and internal layer, can make them integrated by the whole bag of tricks.As incorporate means, for example can list by heat fusings such as hot pressing line processing, bonding, crosslinked etc. by adhesive by the fiber of current.Internal layer by melt spraying non-woven fabrics make, outer when making by aspunlacednonwovenfa,ric, at the stacked fleece of the one side of melt spraying non-woven fabrics, inject high pressure current from it, make between the fibroreticulate structural fibers and the structural fibers of this structural fibers and melt spraying non-woven fabrics to carry out fiber crosslinked, then, other one side at melt spraying non-woven fabrics is also carried out same processing, thereby obtains flat substrates, and this is easy and economical.
According to the weight per unit area of flat substrates, the thickness of preferred flat substrates is 0.22～1.20mm, and especially preferably 0.24～1.00mm most preferably is 0.26～0.80mm.In addition, the weight per unit area of flat substrates 20～150g/m preferably
2, preferred especially 50～100g/m
2Thickness and weight per unit area just can fully improve the maintenance performance of liquid if in this scope.Weight per unit area is, flat substrates is cut into the size of 100mm * 100mm, measures its weight, is scaled 1m
2Weight obtain.Thickness is, flat substrates is cut into the size of 100mm * 100mm, at 20gf/cm
2Loading measure down.
The saturated solution scale of construction of flat substrates preferably per unit weight is 50～1000%, especially preferably 100～600%.Can preserve the liquid of abundant amount thus.The saturated solution scale of construction depends on the character by formed space of the fiber that constitutes flat substrates and fiber itself.Therefore, be not as long as merely the reduced thickness of flat substrates just can be improved the maintenance performance of liquid, improve in order to make this performance, must also to consider saturated liquid measure.Base material is cut into the size of 100mm * 100mm, measures its weight.The dipping flat substrates made the liquid drippage more than or equal to 1 minute more than or equal to 15 minutes after the taking-up in ion exchange water, and gravimetry, can obtain saturated liquid measure by the weight difference that calculates the dipping front and back.
In the flat substrates of the present invention, for make it the dipping and keep various liquid, except that the hydrophilic fibre that contains more than or equal to 55 weight %, preferably make with following formula represent 70～99%, preferred especially 85～99% voidage.If voidage is more than or equal to 70%, just can keep liquid fully, if voidage is smaller or equal to 99%, productivity ratio is improved.
Voidage (%)=(ρ-ρ ')/ρ * 100
In the formula, ρ represents the proportion of sheet, the apparent specific gravity of ρ ' expression sheet.
Flat substrates of the present invention becomes the wet sheet that is impregnated with various liquid.The kind of the liquid that is flooded can be selected suitable liquid according to the concrete purposes of wet sheet.For example, when wet sheet is used as the cosmetic Compond fibre table for removing lipstick and uses,, can use the waterborne liquid, O/W emulsification class emulsion, W/O emulsification class emulsion, oil-base gel, frost, the oil that contain surfactant as liquid.Especially preferably contain the aqueous solution of nonionic surface active agent and glycerine, preferred above-mentioned nonionic surface active agent is the mono laurate polyethylene glycol again.When being purpose with the washing of the cosmetic of skin attachment height, water-based and oil-based cosmetics such as mascara, preferably contain the finish of 160～300 ℃ of boiling points of 0.01～0.5 quality % water system tackifier, 5～30 weight % and moisture O/W emulsification class emulsion, above-mentioned finish is more preferably the O/W emulsification class emulsion of the isoparaffin of 160～300 ℃ of boiling points.As isoparaffin, can commodity in use マ Le カ ゾ one Le R (ball is apt to petrochemistry (Maruzen Petrochemical Co., Ltd) Co., Ltd. produces) or IP SOLVENT1620,2028 (bright dipping petrochemistry (Idemitsu Petrochemical Co., Ltd) Co., Ltd. produces) etc.
The pickup of liquid in flat substrates, although relevant with the concrete purposes of wet sheet, the per unit weight of flat substrates preferred 100～600%, preferred especially 200～450%.In addition, the viscosity of liquid is 1～1000000mPas preferably, if consider coating, is more preferably 1～70000mPas.
Even the wet sheet that obtains like this with the overlapping preservation of its multi-disc, also can suppress moving of liquid.Although since impregnation liquid, the apparent density of each layer in the wet sheet with make liquid infiltration before flat substrates in the apparent density of each layer different, two density do not have big difference.In addition, even and the distance dependent between the fiber of each layer of wet sheet, and make distance bigger difference not between the fiber of each layer in the flat substrates before the liquid infiltration.Therefore, can suppress the moving of liquid in the wet sheet.
The wet sheet that possesses flat substrates of the present invention can be used as health wiping sheet.For example can be suitable for removing ornaments and formal dress with sheet, antiperspirant sheet, clear up a messy situation to settle an impasse and use sheet etc.
