Summary of the invention
The problem that invention is to be solved
But, only comprise cellulose fibre non-woven fabrics (the most only comprise the non-woven fabrics of cellulose-based regenerated fiber,
The most same) shape of non-woven fabrics is only maintained by fiber intertexture each other, therefore the mechanical strength of non-woven fabrics is low, and moistening
Time can become lower than time dry.For example, as it is known that: although the viscose rayon yarn as one of cellulose-based regenerated fiber passes through to the greatest extent
Reduce inorganic compound (specifically can enumerate the inorganic compound such as titanium oxide, zinc oxide) contained in viscose rayon yarn possibly
Content and under moisture state, demonstrate high transparency sense, but, the non-woven fabrics being only made up of this viscose rayon fibers is moistening
Under state lower than the intensity under drying regime.With regard to base material use this non-woven fabrics and containing being soaked with the sheet material of cosmetic preparation for, even if right
When it applies small power, the power such as applied non-woven fabrics when sheet material is taken out in commodity packaging, the sheet material that will fold launch pair
, also can there is the risk that sheet material occurs to stretch and shape is destroyed in the power that non-woven fabrics applies.It addition, only by cellulose fibre structure

Cellulose-based regenerated fiber refers to the fiber after cellulose dissolution is regenerated as threadiness.For cellulose-based again
For raw fiber, although always according to the amount i.e. ash of inorganic compound contained in fiber, the composition of inorganic compound and different, but
It is under moisture state, easily to demonstrate extra high transparent feel, the most preferably.As the fiber that can use in the present invention
Prime system regenerated fiber, can enumerate viscose rayon yarn, solvent spinning fibre element (or also referred to as refined cellulose) and cuprammonium artificial
Silk, they are hydrophilic, and demonstrate extra high transparent feel under moisture state.Wherein, viscose rayon yarn is being used
In the case of, the effect that operability described later improves is notable.Solvent spinning fibre element is also referred to as Lay haussaire (lyocell), with
The title listings such as Tencel (registered trade mark).Copper rayon is also referred to as CUP.The fiber of cellulose-based regenerated fiber cuts open
Face can be the arbitrarily form such as circular, square, Flos Chrysanthemi shape, such as, can be circular or Flos Chrysanthemi shape.Cellulose-based
In the case of regenerated fiber has the fibre profile of Flos Chrysanthemi shape, the non-woven fabrics finally given has under moisture state skins such as faces
The advantage that skin demonstrates extra high adaptation (stickiness).Can be suitable for obtaining the fiber of Flos Chrysanthemi shape when for viscose rayon yarn
Section.On the other hand, in the case of cellulose-based regenerated fiber has the fibre profile of circular, have and can reduce light
Diffuse-reflectance, make the advantage that the non-woven fabrics finally given demonstrates extra high transparent feel under moisture state.Spinning for solvent
Can be suitable for obtaining the fibre profile of circular in the case of silk fiber element or copper rayon.Cellulose-based semisynthetic fibre
Refer to by cellulose for chemical reaction fiber obtained by synthetic fibers shape.As the cellulose that can use in the present invention
It is semisynthetic fibre, diacetate esters and triacetate can be enumerated.
In the 1st cellulose fibre described in the present invention, refractive index is that the content of the inorganic compound of more than 1.6 is
Below 0.5 mass %.Different from the present invention, viscose rayon yarn used in general non-woven fabrics, solvent spinning fibre element,
In copper rayon, diacetate esters, triacetate, the powder of inorganic compound high for the refractive index such as titanium oxide, zinc oxide is made
For in raw material during for suppressing the delustering agent (or may also be referred to as screening uv-ray agent) of gloss to add spinning to.So
And, comprise the cellulose fibre of this inorganic compound a large amount of transparent feel step-down under moisture state.Therefore, institute in the present invention
The 1st cellulose fibre said does not comprises the inorganic compound that refractive index is more than 1.6 preferably as far as possible, and refractive index is more than 1.6
The content of inorganic compound be necessary for below 0.5 mass %.As the example of the inorganic compound that refractive index is more than 1.6,
Titanium oxide, zinc oxide, aluminium oxide, barium sulfate etc. can be enumerated.As this cellulose fibre, it is possible to use be classified as so-called
The fiber " having light ".In contrast, it is more to be classified as the content of titanium oxide in the fiber of so-called " delustring " or " semi-dull ",
It is said that in general, be about about 1 mass % in the fiber of " delustring ", it is that 0.5～0.6 mass % is left in the fiber of " semi-dull "
The right side, thus the most preferred.Refractive index is that the content of the inorganic compound of more than 1.6 is preferably below 0.3 mass %, is more preferably 0.2
Below quality %, below particularly preferably 0.1 mass %.
The 1st cellulose fibre that can use in the present invention be refractive index be the content of the inorganic compound of more than 1.6
Meet above-mentioned condition and fiber that ash is below 5 mass %.That is, can list suppression refractive index as far as possible is more than 1.6
The content of inorganic compound, the amount of the whole inorganic compound of ash shared in cellulose fibre is suppressed relatively simultaneously
Low cellulose fibre.This kind of cellulose fibre transparent feel under moisture state is high and the whole inorganic chemical of ash
The content of thing is low, and therefore hydrophilic is high, and it is excellent that water-retaining property protects fluidity.As the 1st cellulose fibre meeting this condition
Concrete example, can enumerate " the BH artificial silk " peddled by DAIWABO RAYON (strain), " Tencel peddled by LENZING company
(registered trade mark) Skin ".
Other the 1st cellulose fibres that can use in the present invention be refractive index be the inorganic compound of more than 1.6
Content meets above-mentioned condition, the content of the refractive index inorganic compound less than 1.6 is more than 5 mass % and 50 mass % with
Under and ash more than 5 mass % and be the fiber of below 50 mass %.That is, can list suppression refractive index as far as possible is more than 1.6
The content of inorganic compound and the cellulose fibre of inorganic compound containing low-refraction.This kind of cellulose fibre exists
High and the whole inorganic compound of ash the content of transparent feel under moisture state is high, and therefore fiber becomes soft fiber, and
The non-woven fabrics of gained also becomes soft non-woven fabrics.As the example of the refractive index inorganic compound less than 1.6, dioxy can be enumerated
SiClx, mineral (such as kieselguhr) with silicon dioxide as main constituent, sodium silicate, sodium sulfate etc..As meeting the 1st of this condition
The concrete example of cellulose fibre, can enumerate " FR ", " FRL " peddled by DAIWABO RAYON (strain).
1st cellulose fibre preferably has hydrophilic, does not the most comprise carboxyl or carboxymethyl.
The fibre length of the 1st cellulose fibre suitably can select in the scope of more than 20mm and below 110mm.
This fibre length can obtain fluffy and good feel and operability, and can obtain utilizing at current intertexture described later
The sheet material that reason is soft while making easily to interweave between fiber and having toughness when hand-held, transparent feel is high.1st is cellulose-based
Fiber can be so-called staple fiber (staple fiber).The fibre length of the 1st cellulose fibre be preferably 28mm with
Go up and below 96mm, more preferably more than 32mm and below 72mm, particularly preferably more than 38mm and below 64mm.
From the viewpoint of obtaining high transparency sense, the fiber number of the 1st cellulose fibre is the thickest more preferred.It is believed that: if fine
Degree is thick, then number of fiber reduces, and reduces the diffuse-reflectance of light.But, if fiber number is the thickest, then the adaptation (stickiness) of skin is dropped
Low, skin sense of touch is deteriorated (twinge).The fiber number of the 1st cellulose fibre is not particularly limited, for example, more than 0.4dtex and
Below 4.4dtex, be preferably more than 0.6dtex and below 3.3dtex, particularly preferably more than 0.8dtex and 2.8dtex with
Under.
Thermal bonding fiber refers to because heat treatment can make the fiber that at least partly melts.Heat treatment temperature can basis
The composition of thermal bonding fiber suitably selects.This thermal bonding fiber is utilized to make the cellulose-based mixed fiber layer of composition
At least one of the intersection point of fiber is heat-bonded (fixing).Cellulose-based mixed fiber layer has the fiber being heat-bonded in a large number
Intersection point (fixing point) contributes to operability (mechanical strength, the elasticity etc. improving the non-woven fabrics finally given under moisture state
And the extensibility under moisture state and resistance to extensibility).Cellulose-based mixed fiber layer (in the present embodiment, is and contains
The skin covering sheet non-woven fabrics of makeup material of macerating is overall) if in the content of thermal bonding fiber be more than 8 mass % and 40
Below quality %, in order to obtain higher operability, do not damage the non-woven fabrics finally given at moisture state under saturating
In the range of bright sense the highest more preferred, can be such as below more than 9 mass % and 37 mass %, more preferably 10 mass % with
Go up and below 35 mass %, more than particularly preferably 10 mass % and below 32 mass %.
For thermal bonding fiber, typically synthetic fibers, preferably comprise fusing point higher (such as more than 140 DEG C)
The composition (hereinafter referred to as " high-melting-point composition ") of thermoplastic resin and the heat of fusing point lower than high-melting-point composition (such as less than 140 DEG C)
The composition (hereinafter referred to as " low melting point composition ") of plastic resin and low melting point composition occupy at least one of multiple of fiber surface
Condensating fiber.Fusing point is the fusing point of the resin after becoming fiber, it is possible to use the DSC curve measured according to JIS K7121 (1987)
Try to achieve.By this composite fibre being carried out heat with the temperature more than not enough fusing point of high-melting-point composition and the fusing point of low melting point composition
Process, thus high-melting-point composition can be remained and make low melting point components fuse simultaneously and with other fiber weldings, therefore can be by fibre
It is securely engaged between dimension.
It is poor, more excellent that high-melting-point composition preferably has fusing point sufficient with low melting point composition fusing point poor, preferably more than 5 DEG C
Select more than 10 DEG C fusing point difference and at a temperature of by low melting point components fuse will not because of heat and the composition of deformation etc..High-melting-point becomes
Dividing can be polyolefin-based resins or polyester based resin, and low melting point composition can be to have gathering of the fusing point lower than high-melting-point composition
Olefin-based resin.As the concrete combination of high-melting-point composition/low melting point composition, can enumerate polypropylene, polyethylene, polypropylene/
Ethylene-propylene copolymer, polyethylene terephthalate/polyethylene, polyethylene terephthalate/ethylene-propylene are common
Polymers etc..Polyethylene comprises high density polyethylene (HDPE), Low Density Polyethylene, straight-chain Low Density Polyethylene etc..
More specifically, thermal bonding fiber can be sheath-core type conjugate fiber.Sheath-core type conjugate fiber is core and sheath
The composite fibre that portion is made up of 2 kinds of different compositions, core is not particularly limited with the configuration in sheath portion, i.e. in fibre profile,
Can be the core composition single that is present in 1 position, it is also possible to be present in the multicore at more than 2 positions for core composition.It addition,
Fibre profile SMIS composition can be the concentric circular that core composition and sheath composition are configured to concentric circles with the position relationship of sheath composition
Type, it is also possible to for the eccentric type that configures of core composition deviation ground, it is also possible to the parallel type configured side by side for core composition and sheath composition is (also
It is referred to as side by side (side by side)).In the skin covering sheet non-woven fabrics of the impregnation cosmetic preparation of the present invention, need with less
The content of thermal bonding fiber make non-woven fabrics entirety equably and with the most strongly by heat bonding between fiber, the most preferably
Use sheath-core type conjugate fiber that be evenly distributed low melting point composition at fiber surface, that there is concentric ring type fibre profile.
Sheath-core type conjugate fiber such as can be by comprising the 1st polyolefin-based resins or polyester based resin (high-melting-point composition)
Core has the 2nd of the fusing point lower than the fusing point of the 1st polyolefin-based resins or polyester based resin (high-melting-point composition) with comprising
The sheath portion of polyolefin-based resins (low melting point composition) is constituted.Specifically, high-melting-point composition can be polypropylene, poly-methylpent
Alkene, polyethylene terephthalate, PTT etc., preferably polypropylene, low melting point composition can be
High density polyethylene (HDPE), Low Density Polyethylene, straight-chain Low Density Polyethylene, ethylene-propylene copolymer, PB Polybutene-1 etc., preferably
For high density polyethylene (HDPE).
From the viewpoint of obtaining high transparency sense, the fiber number of sheath-core type conjugate fiber is the thickest more preferred.It is believed that: if fiber number
Slightly, then number of fiber reduces, and reduces the diffuse-reflectance of light.But, if fiber number is the thickest, then the fiber intersection point (fixing point) being heat-bonded
Quantity reduce, therefore exist operability raisings effect reduction risk.And, if the fiber number mistake of sheath-core type conjugate fiber
Slightly, then exist the sense of touch of non-woven fabrics hardening or when making non-woven fabrics contact skin excitement (sense of touch of such as twinge) become strong
And it is not suitable as being impregnated with the risk of the base fabric of the skin covering sheet of cosmetic preparation.The fiber number of sheath-core type conjugate fiber is for example,
More than 0.5dtex and below 4.0dtex, more preferably more than 0.8dtex and below 3.6dtex, particularly preferably 1.2dtex with
Go up and below 2.8dtex, most preferably more than 1.4dtex and below 2.6dtex.
It addition, thermal bonding fiber can be the fiber from Splittable conjugate fiber.Splittable conjugate fiber is by 2 kinds
The composite fibre that above composition is constituted, it can be by segmentation and forms the much less fibers of fiber number from 1 fiber
Fiber." from the fiber of Splittable conjugate fiber " refers to: before being formed by the segmentation of Splittable conjugate fiber, splitting
The Single Fiber being only made up of a section and the fiber being made up of the section of more than 2 and 1 Splittable conjugate fiber
The a part of divided but the most divided fiber of other parts.Or, as long as cellulose-based mixed fiber layer comprising logical
The segmentation of over-segmentation type composite fibre and the fiber that formed, then in the case of 1 Splittable conjugate fiber is the most divided,
The most divided Splittable conjugate fiber of this kind is also contained in the fiber of Splittable conjugate fiber.
Specifically, Splittable conjugate fiber has following fibre profile structure: in fibre profile, in constituent
At least 1 composition is divided into more than 2, at least some of exposed fiber surface of constituent, and this exposed portion is at fiber
Length direction be continuously formed.
Such as, Splittable conjugate fiber can be by the 1st polyolefin-based resins or polyester based resin (high-melting-point composition) and tool
Have than the 1st polyolefin-based resins or the 2nd polyolefin-based resins of the low-melting fusing point of polyester based resin (high-melting-point composition)
The combination of (low melting point composition) is constituted.Specifically, high-melting-point composition can be polypropylene, polymethylpentene, poly-terephthaldehyde
Acid glycol ester, PTT etc., preferably polyethylene terephthalate, low melting point composition can be
High density polyethylene (HDPE), Low Density Polyethylene, straight-chain Low Density Polyethylene, ethylene-propylene copolymer, PB Polybutene-1 etc., preferably
For high density polyethylene (HDPE).
As long as the fiber number of Splittable conjugate fiber while becoming a fiber (that is, each section) when being divided into each composition provides
Superfine fibre below fiber number 0.6dtex, below preferred fiber number 0.5dtex, then be not particularly limited.In the present invention, just come
For the fiber of Splittable conjugate fiber, it comprises the superfine fibre being made up of low melting point composition, and this superfine fibre is by fiber
At least some of heat bonding of intersection point each other.If the fiber number of the superfine fibre being made up of low melting point composition is below 0.6dtex,
The most hot sticky contact is little, is therefore difficult to make non-woven fabrics become really up to the mark, therefore is difficult to damage the texture of non-woven fabrics.
In order to produce this kind of superfine fibre, the fiber number of Splittable conjugate fiber be preferably more than 1.1dtex and 5.8dtex with
Under, more preferably more than 1.3dtex and below 4.8dtex, more preferably more than 1.4dtex and below 3.6dtex, optimum

The property opened and resistance to extensibility) non-woven fabrics that is improved.
The non-woven fabrics of present embodiment can manufacture in such a way.
First, the fibre length preparing to comprise more than 50 mass % is more than 20mm and below 110mm the 1st cellulose-based
The cellulose-based composite fibre sheet of the thermal bonding fiber more than fiber and 8 mass % and below 40 mass %.1st is cellulose-based
Fiber and thermal bonding fiber are suitable for explanation similar to the above.But, in this stage, the intersection point constituting fiber is the most hot sticky
Connecing property fiber heat bonding, in the case of using Splittable conjugate fiber as thermal bonding fiber, can be undivided.This fibre
Dimension prime system composite fibre sheet is the precursor of above-mentioned cellulose-based mixed fiber layer, unless otherwise specified, is just suitable for fine
The explanation that dimension prime system mixed fiber layer is same.
This cellulose-based composite fibre sheet can be the form of knitmesh, it is also possible to for by interweaving and/or bonding etc. and make
The form of the non-woven fabrics of fiber combining, when arbitrary form, can be monolayer, it is also possible to be the duplexer of more than 2 layers.?
In the case of cellulose-based composite fibre sheet is knitmesh, can be such as comb and parallel cotton fibers prior to spinning knitmesh, more specifically, can be parallel knitting

Density portion ", it is normally present in longitudinal direction (MD), but is not limited to this.In the low fibre density portion of this striated, fibre weight
Less, therefore available high transparency sense under moisture state.It addition, in the low fibre density portion of striated, fibre weight is less, because of
This is easily at direction (the usually width orthogonal with the direction in the low fibre density portion of striated (generally longitudinally (MD))
(CD)) upper elongation.And, it is believed that: in the case of other cellulose fibre sheets comprise the 2nd cellulose fibre, the 2nd is fine
Dimension prime system fiber, owing to fibre length is short and be hydrophilic, is the most easily peeled off and the most washed away by column current, and ties
Really: in the low fibre density portion of striated, fibre weight becomes the fewest, higher transparent feel and resistance to extensibility can be obtained.?
In the sheet material of final gained, the cellulose-based mixed fiber layer (feelings at 3-tier architecture with the 1st cellulose fibre as main constituent
For upside fibrous layer and downside fibrous layer under condition) under moisture state, demonstrate extra high transparent feel as mentioned above.With this phase
Right, other cellulose fibre layers with the 2nd cellulose fibre as main constituent are (as median fiber in the case of 3-tier architecture
Layer) Comparatively speaking can give play to the function of the liquid retainability (guarantor's fluidity) undertaken under moisture state with transparent feel.And, can recognize
For: in the case of current interleaving treatment applied as described above, especially can effectively reduce it in the low fibre density portion of striated
The fibre weight of his cellulose fibre layer, can improve transparent feel and the extensibility of other cellulose fibre layers, and then permissible
Improve transparent feel and the extensibility of the sheet material entirety of final gained further.
Based on above result, cellulose-based composite fibre sheet and other cellulose fibre sheets or long fibre nonwoven pieces of cloth
Respectively become cellulose-based mixed fiber layer and other cellulose fibre layers or long fibre nonwoven layer of cloth, thus can manufacture this
The non-woven fabrics of embodiment.
