The ora terminalis 33a of 21 side of the 1st end edge portion 33 is located at pars intermedia 19.Opening edge 51 can also be positioned at the 1st end of cotton pads 10
17 structure.
In the cotton pads 10, the pad of makeup removing can be used as in the 1st face 11 or the coating cleaning agent of the 2nd face 12, or,
In order to wipe the dirt of pore or remove old cutin, in the 1st face 11 or (the so-called wiping cosmetic of the 2nd face 12 coating toner
Water) and as toner pad.When wiping and making up, the 1st face 11 or the 2nd face 12 of cotton pads 10 are pressed on into skin and
Wipe, therefore, compared with the facial mask for infiltrating toner and being used with face contact, it is desirable to the journey of the imperceptible stimulation of user
The required flexibility of degree.Especially, infiltrate wiping toner in the case of use, by the dirt of pore, old
The comparison of the degree of imperceptible stimulation high flexibility is required while cutin is got rid of.
For the cotton pads 10 in present embodiment, the outer layer 24 in the 1st face 11 and the 2nd face 12 is formed by be used as average fibre
Dimension diameter is that the fabric nonwoven cloth based on the moisture-absorbing fibre (the 1st fiber 26) of less than 10 μm of superfine fibre is formed, therefore, with
The situation for forming outer layer by the fabric nonwoven cloth than larger fibre diameter is compared, and can reduce excitement, obtains soft flesh
Skin sense of touch.Moreover, the superfine fibre is meltblown fibers, therefore, with using segmentation fiber type compared with the situation of superfine fibre,
Fibre diameter can be made uniform, and make the side face of fiber smooth, soft skin sense of touch can be further improved.In addition, internal layer
23 based on the avarage fiber diameter cellulose fibre bigger than the avarage fiber diameter of moisture-absorbing fibre, therefore, by using
Superfine fibre, can prevent the intensity decreases of covering piece 21.
That is, covering piece 21 only by superfine fibre formed in the case of to be possible to toughness weaker and can not stably wipe angle
Matter etc., however, (the 2nd is fine by being laminated by the avarage fiber diameter hygroscopicity fibre bigger than the avarage fiber diameter of superfine fibre
Tie up the internal layer 23 of 27) composition to support the outer layer 24 being made up of superfine fibre (the 1st fiber 26), so that covering piece 21 has institute
Need toughness and can stably wipe cutin etc..
In addition, in the case where internal layer 23 contains hydrophobic thermoplastic fibre, hygroscopicity/water imbibition drop of internal layer 23
Low, therefore, the effect that introducing is held the skin lotion of outer layer 24 etc. is suppressed, and the effect can be made further to improve.And
And, the 1st side edge part 31 and the 2nd side edge part 32 that stacking is got up are by the sludge ice based on heat or ultrasonic/heavy flower processing two
When side engagement portion 44 carries out heat bonding, internal layer 23 relative to each other and outer layer 24 are engaged, but two layers of composition fiber is different, because
This, bond strength is possible to step-down.Thermoplastic fibre is contained by internal layer 23, so that the bond strength at two side engagement portions 44 is carried
Height, can prevent the part from peeling off in use.
The manufacture method of ＜ covering pieces>
Constitute covering piece 21 outer layer 24 and internal layer 23 can by mechanical intertexture method, fluid intertexture method (current intertexture method,
Air entanglement), acupuncture intertexture method and it is integrated, it is preferably integrated by current intertexture method.As long as playing this Shen described later
Please The effect of invention, can also be engaged by using bonding agent (adhesive) two layers 23,24 and form covering piece 21, but pass through water
Stream intertexture method makes two layers 23,24 integrations, and the flexibility of covering piece 21 is excellent, and skin sense of touch is good.
Fig. 4 is the side view for schematically showing the main part in the manufacturing process of covering piece 21, and Fig. 5 is covering piece
21 enlarged partial isometric view.Reference picture 4 and the major part in manufacturing process is described, first, stacking is turned into interior
Layer 23 the 1st fiber mesh material 91 (lower floor) of material and the 2nd fiber mesh material (upper strata) 92 of the material as outer layer 24 and
Into fibrous layer 93 under the jet-action of High-Pressure Water to operating direction MD convey.Alternatively item and while being supplied from tank 94
Moisture film is while make the form stable of fibrous layer 93, afterwards, is guided to the mesh screen of the ring-type banding as perforate supporting mass 95, makes to take out
Suction portion 96 works and draining below the sieve aperture, also, from it from multiple nozzles with predetermined diameter spacing
97 throttle orifice injection High-Pressure Water.Multiple nozzles 97 are configured with along the direction (crisscross) intersected with operating direction MD.
Although not shown, but mesh screen is multiple wire rods by stainless steel intersected with each other (for example, the wire rod and latitude of orthogonal warp
Wire rod) formed by plain weave knits, with wire rod multiple tuberal parts intersected with each other.In this manufacturing process, pass through outer layers
24 side sprays penetrate High-Pressure Water, thus skin with respect to surface side flatness improve and skin sense of touch becomes good, but as long as after playing
The effect of the present application stated, just both can penetrate High-Pressure Water with the side spray of inner layer 23, can also be from the side of internal layer 23 and outer layer 24
Spray High-Pressure Water in this two sides of side.
By the spray treatment, the fiber of the 1st fiber mesh material 91 and the fiber interweaving of the 2nd fiber mesh material 92, also,
In the fiber of the fiber mesh material 91 of composition the 1st on perforate supporting mass 95 be located at tuberal part on fiber injection water effect
Lower movement, so as to be arranged again on tuberal part periphery, forms the perforate 80 in the absence of the fiber.In addition, in the 1st fiber mesh material
91, formed in the presence of the High-Pressure Water from the injection of multiple nozzles 97 along crisscross arrangement along crisscross arrangement
Multiple groove portions 82, also, formed be located at groove portion 82 between convex strip portions 81.Perforate 80 is located at groove portion 82.On the other hand, high pressure
The 2nd fiber mesh material 92 that current directly spray is than relatively thin, and in the superfine fibre such as nylon random alignment, fiber can be moved each other
In the state of by spray treatment, therefore, multiple perforates 80, fiber will not be formed by figuration as the 1st fiber mesh material 91
Mutual intertexture can be untied and similarly extended, so as to form netted.Therefore, the superfine fibre of the 2nd fiber mesh material 92 is constituted
It is also to exist in the way of blocking the perforate 80 at the perforate 80 of the 1st fiber mesh material 91.
5~Fig. 7 of reference picture, in the covering piece 21 being manufactured into by already described manufacture method, constitutes the superfine of outer layer 24
The 1st fiber 26 similarly extend and form netted, therefore, when pressing it against in face to be wiped, the energy of the 1st fiber 26
Enough face powder, sebum etc. are scraped into pore, function is brushed so as to play.In addition, the 1st fiber 26 of agent of low hygroscopicity is in skin
Extension is reticulated on bearing surface, so that the skin lotion for being infiltrated up to cotton pads 10 forms similarly extend big in skin abutment face
Uniform liquid film is caused, is improved with the adaptation of skin, in the case of as Cosmetic pack, can be played and skin well docile
Property.
Reticulate in addition, outer layer 24 is more thickly configured by the 1st fiber 26 and be formed with smaller fibre gap, because
This, compared with the situation that fibre gap is formed with multiple perforates 80 than larger situation, as internal layer 23, the liquid of skin lotion etc.
Retentivity is good.Thus, even making in the case that the skin lotion of fewer amount is infiltrated up to cotton pads 10, skin lotion also will not
By the transient absorption of cushion 20, the outer layer 24 in moisture state can be utilized to wipe face powder, the dirt of skin.In covering piece
In 21, preferably convex strip portions 81 and groove portion 82 extend along the 1st direction S or the 2nd direction R, in the present embodiment, the He of convex strip portions 81
Groove portion 82 extends along the 2nd direction R and is alternately arranged on the 1st direction S.
In addition, internal layer 23 is formed by avarage fiber diameter the 2nd fiber 27 bigger than the avarage fiber diameter of the 1st fiber 26,
And with concavo-convex, therefore, with required piece intensity.Thus, covering piece 21 is overall to have appropriate toughness, is slided with skin
It is dynamic to suppress that outer layer 24 is twisted when contacting and the wiping operation stablized.In addition, being moved to internal layer 23 from outer layer 24
Skin lotion spreads along 82 inner layer of groove portion 23 is overall, and is quickly removed from multiple perforates 80 to cushion.
It is further preferred, that formed outer layer 24 the 1st fiber 26 by along the 1st direction S, the 2nd direction R extend and the 1st
The continuous fiber (continuous fiber) of terminal part on the face 12 of face 11 and the 2nd in the absence of fiber is formed.It is in the 1st fiber 26
In the case of chopped fiber (staple) as there is the terminal part of fiber on 1 face 11 and the 2nd face 12, when use, the end
End is possible to encounter skin and bring skin stimulation, but exists only in the 1st side edge part 31 and the 2nd side by using terminal part
Edge 32, the continuous fiber on the 1st face 11 and the 2nd face 12, compared with the situation using chopped fiber, it is possible to increase skin is touched
Sense.In such outer layer 24, it is preferred that the 1st fiber 26 is long fibre, in the state of fibrous layer 93, fibre length ratio
It is longer, for example, bigger than the size on the 1st direction S of cotton pads 10 and/or the 2nd direction R.Referring again to Fig. 1 and Fig. 3, in this reality
In the cotton pads 10 for applying mode, it is formed with the inner side of the both side edges 13,14 on the cut-out side as covering piece 21 of cotton pads 10
Two side engagement portions 44, therefore, skin lotion the area of application delimited by two side engagement portions 44 and two ora terminalis 15,16 in the 2nd face 12
In, the terminal part of the moisture-absorbing fibre of continuous fiber is not existed as, good skin sense of touch is resulted in.
In the case where internal layer 23 contains hydrophobic thermoplastic fibre, hygroscopicity/water imbibition reduction of internal layer 23, because
This, the effect that introducing is held the skin lotion of outer layer 24 etc. is suppressed, and the effect can be made further to improve.Moreover,
Two side engagement portions 44, the sludge ice of the 1st side edge part 31 got up in stacking and the utilization of the 2nd side edge part 32 based on heat or ultrasonic/heavy
When flower processing carrys out heat bonding, internal layer 23 relative to each other and outer layer 24 are engaged, but two layers of composition fiber is different, bond strength
It is possible to step-down.Contain the bond strength at thermoplastic fibre, two side engagement portions 44 by internal layer 23 to improve, the portion can be prevented
Divide and peel off in use.
In the skin abutment face of cotton pads 10, average surface coefficient of friction (MIU) is more than 0.35, surface roughness it is flat
Equal deviation (SMD) [unit：μm] it is less than 1.20.Moreover, the average surface coefficient of friction (MIU) of skin abutment face is preferably
Less than 0.45, the average deviation (SMD) of surface roughness is more preferably less than 1.00.The average deviation of skin-friction coefficient
(MMD) it is preferably less than 0.010.
So, it is less than 10 μm of superfine fibre by using avarage fiber diameter and makes average surface coefficient of friction
(MIU) it is, up to more than 0.35 that can make the silk smooth felling (Japanese of skin abutment face than higher：ぬ め り feel) increase and make it
Such sense of touch (closely sealed sense) can be adsorbed by skin by possessing.Moreover, for surface roughness average deviation (SMD) be 1.20 with
Lower i.e. concavo-convex less flat wiping surface, by making average surface coefficient of friction higher, can will go into the dirt of pore
Scrape.In the cotton pads 10 of present embodiment, outer layer 24 contains the 1st superfine fiber 26, therefore, is formed in skin abutment face
Less multiple marginal portions, with relatively higher frictional resistance, by forming the marginal portion in concavo-convex less plane,
When wiping, the fine dirt that pore can be just will go into without firmly wiping skin is scraped, and wiping is excellent.Covering piece
21 superfine fibre layer (outer layer 24) is carry by internal layer 23, accordingly, it is difficult to produce damaged, twisted, it is easy to make superfine fibre (the
1 fiber 26) it is closely sealed with skin, especially, in the state of cleaning agent etc. is coated with, with situation of the individual layer using superfine fibre layer
Compare, wiping can be improved.In addition, by the way that the average deviation (MMD) of skin-friction coefficient is set into less than 0.010, energy
Smooth skin sense of touch is enough obtained, so, by making the average deviation of surface roughness and the average deviation of skin-friction coefficient
Both is smaller, when skin lotion is coated with, it is easy in the liquid film of skin abutment face formation evenly, can make closely sealed sense
Further improve.
In addition, for cotton pads 10, dripped the indigo plant with 0.005 mass % to skin abutment face on thickness direction Z
