(structure and material of main part)
Forming under the situation of multilayer, preferred one deck at least, for example the internal layer 2B in the double-decker shown in Figure 2 or the intermediate layer 2C in the three-decker shown in Fig. 4, Fig. 6 have the functional layer that function, aromatic function, virus/anaphylactogen deactivation function, antibacterial functions, the shape of filtering dust etc. keep function etc.
For this functional layer, preferred dismounting is contained in the mode on the main part 2 freely.For example, as shown in Figure 6, under the situation of intermediate layer 2C as functional layer with three-decker, the ora terminalis (perhaps also can be the opening of being located on outer 2A or the internal layer 2B) by main part 2 freely picks and places functional layer 2C, dismounting functional layer freely thus.And, also can adopt this layer structure that constitutes by a plurality of layers at holding division.
Herein, no matter main part is individual layer or sandwich construction, the invention is characterized in, the layer of the face of the formation of main part and facial contact is a nonwoven at least, and, all or part of smooth agent that contains of main part and face facial contact.That is to say, the invention is characterized in, constitute with the nonwoven layer of the face of facial contact, with the face of facial contact all or part of on infiltration or coating smooth agent, thereby make it contain smooth agent.In addition, what make easily is the nonwoven fabric construct of individual layer and the mode that applies smooth agent on entire contact surface, but also can be only to make the mode that is easy to contain with the part of skin friction smooth agent.
Herein, as the part that is easy to skin friction, can enumerate: among Fig. 7 with square main part be shown in the example like that, require the part with the adaptation of skin in order to prevent entering of dust, pollen etc., i.e. the circumference A of the face that contacts with skin 20 of main part; And among Fig. 8 equally with square main part be shown in the example like that, be easy to the part that contacts with nose, promptly in the face that contacts with skin 20 of main part, near the part B center line that extends longitudinally at the left and right directions center.Therefore, can be near the mode of B coating smooth agent etc. this circumference A or center line only.Certainly, also can be the mode of coating smooth agent on these two parts A, B.In addition, circumference A is meant, is roughly 1～5cm apart from the distance L 1 of main part Zhou Duanyuan E, the scope about 2～3cm preferably, B is meant near the center line, apart from the distance L 2 of center line C towards about (holding division direction) be roughly 1～3cm, the preferably scope about 1.5～2cm.In addition, though not shown among the figure, under the situation of the main part that adopts three-dimensional shape illustrated in figures 1 and 2, only equally also can form near the mode of the coating smooth agent circumference of main part and center line.
As smooth agent, can use the known smooth agent that in health tissue papers such as face tissue etc., uses herein.Specifically can enumerate, containing wax, MPC polymer, glycerine, diglycerol, mean molecule quantity is polyethylene glycol, D-sorbite, the propane diols, 1 of 200 above less thaies 1000, the smooth agent of more than one in 3-butanediol, glycinebetaine, 2-pyrrolidone-5-carboxylic acid, pyrrolidone carboxylic acid salt, maltitol, the sodium lactate etc.Preferred wax, MPC polymer, glycerine.
Be manufactured on the mouth mask that contains the mode of smooth agent on described of main part, as long as in advance to being cut to nonwoven base (Woven cloth is not anti-) coating or the infiltration smooth agent before the main part size.For example can adopt known method such as spray pattern, roller transfer method the nonwoven base to be carried out coating of smooth agent etc.If adopt online (inline) coating can suitably apply at necessary position, and needn't correspondingly shear spacing (cut pitch) as when the nonwoven base applies the mode of smooth agent.
Like this, under the situation of coating smooth agent etc., the nonwoven as constituting with the layer of facial contact preferably uses hydrophilic nonwoven.So not only can improve the compatibility with smooth agent, make the confining force excellence of smooth agent, it is dry that it is difficult for, and further reduces the stimulation to skin.As hydrophilic non-woven, can enumerate the nonwoven, the nonwoven that has adopted staple fibre that have adopted through the fiber of hydrophilicity-imparting treatment, adopt cotton nonwoven etc., or slurry hybrid nonwoven cloth etc.
The coating amount of smooth agent is 1～15gsm, is preferably 3～8gsm, is preferably 4～6gsm especially.If coating amount less than 1gsm, then a little less than the moistening effect, if surpass 15gsm, then becomes and is clamminess, sense of discomfort is arranged on the contrary.
Herein, on the other hand owing to can further reduce stimulation to skin, so the face of the formation of preferred main part and facial contact layer partly or entirely make by melt spraying non-woven fabrics.In addition, what make easily is single layer structure and whole modes of being made by melt spraying non-woven fabrics of layer, but also can be only to make the mode that the part with skin friction is made of melt spraying non-woven fabrics that is easy to.Herein, what is called is easy to the part with skin friction, is the circumference A and the part B that is easy to contact with nose of aforesaid mask main body portion.
The manufacturing of melt spraying non-woven fabrics can be adopted existing known method, for example, raw polymers such as crystallinity propylene class can be melt extruded, utilize the gas of high temperature and high speed, the mode that will be flowed with superfine fibre by the fiber that the melt-blow spinneret spinning obtains melts blows spinning, on capturing devices such as wire netting or band, form superfine fleece, make through bonding process.There is no particular limitation to form the fiber diameter of fiber of this melt spraying non-woven fabrics, is generally about 1～30 μ m, is preferably about 2～10 μ m.
The weight per unit area that constitutes the nonwoven of main part is generally 15～70g/m
2, be preferably 20～60g/m
2If less than 15g/m
2, then be difficult to guarantee necessary strength, if surpass 70g/m
2, sense of touch variation and not preferred then.
On the other hand, main part is being formed under the double-deck situation, formation can be a melt spraying non-woven fabrics nonwoven in addition with the layer layer in addition of the face of facial contact.Therefore, for example can be with utilizing spun-bond process shape spun-bonded non-woven fabrics into the net (S) layer and utilizing meltblown shape melt-blown nonwoven layer of cloth into the net (M) stacked more than 2 layers and the non-woven fabric laminate that obtains uses as the material of mask main body portion.Like this, the part that just can make with the face of facial contact is the main part of the stepped construction of melt spraying non-woven fabrics.
Promptly, when obtaining duplexer, if adopt as inferior method just can be easily will be made melt spraying non-woven fabrics with the part of the face of facial contact: for example, directly will utilize fiber accumulations that meltblown forms after the part (can certainly be whole) of spun-bonded non-woven fabrics goes up and forms melt spraying non-woven fabrics, make the method for spun-bonded non-woven fabrics and melt spraying non-woven fabrics heat fusion; After making spun-bonded non-woven fabrics and melt spraying non-woven fabrics overlapping, make the method for two kinds of nonwoven fusions by the heating pressurization; The method of utilizing bonding agents such as hot-melt adhesive, solvent based bonding agent that spun-bonded non-woven fabrics and melt spraying non-woven fabrics are bonded together.
Herein, the method that directly forms melt spraying non-woven fabrics on spun-bonded non-woven fabrics can be undertaken by following meltblown, that is, and and to the fused mass of part or all spraying thermoplastic resin on the surface of spun-bonded non-woven fabrics, so that fiber accumulations.At this moment, for spun-bonded non-woven fabrics, the face of opposition side that is coated with the face of fused mass one side is a negative pressure, spraying utilizes the fiber of meltblown formation and makes its accumulation, make spun-bonded non-woven fabrics and melt spraying non-woven fabrics integrated simultaneously, thereby obtain having the flexibility non-woven fabric laminate of spun-bonded non-woven fabrics layer and melt-blown nonwoven layer of cloth.Under the integrated inadequate situation of two kinds of nonwoven, can utilize heating pressurization embossing roller to wait and make it integrated fully.
As merging the method that spun-bonded non-woven fabrics and melt spraying non-woven fabrics are merged by heat, have the hot method that merges of the entire contact surface that makes spun-bonded non-woven fabrics and melt spraying non-woven fabrics and making spun-bonded non-woven fabrics and the method for the part heat fusion of the contact-making surface of melt spraying non-woven fabrics.
(material of holding division)
As the material of holding division 3, also can from the same material of main part 2 select, but preferably select to be rich in retractility and elasticity and the material little to the stimulation of skin.
For example, under the situation of the mouth mask 1 of bag type, except pasting nonwoven and implement the lamination nonwoven that processes of raising retractilities such as acupuncture processing as required or in both sides in the table of elastic extension film by the net that is made of the composite fibre with hot crimp property being heat-treated the flexible nonwoven fabrics that obtains, can also be suitable for using following nonwoven, that is, by a pair of nonwoven being sticked together and between nonwoven, accompanying flexible nonwoven fabrics that elastic telescopic parts such as rubber covered wire form etc.
And, for example be under the situation of flat type mouth mask 11, except can from the situation identical materials of the mouth mask 1 of bag type select, can also use for example flat rubber strip (flat go system), rubber ring (ball go system) etc.
In addition, can also will be used for holding division 3 to these materials and the material in the item of main part 2, narrated by the stacked grade material that obtains that combines.
Certainly, so long as in the scope that does not influence the retractility that is used to fix, can adopt with melt spraying non-woven fabrics and form mode holding division and face facial contact, also can apply smooth agent.
