Disposable baby fluids absorbent garment having disposal securing means
The present invention relates to disposable and liquid adsorption type wearing and articles for use, in more detail, it is relatively thinner to relate to knickers liner for example etc., is fit to be used for absorbing the disposable humor absorbent garments of a small amount of body fluid.
In U.S. Pat 4,950, a kind of relatively thinner sanitary towel is disclosed in 264.This sanitary towel has the surface layer of liquid permeability, the water proof damp course of opaque liquid and the absorbency core body between this is two-layer.As the water proof damp course, can use the polyethylene film of gas-permeable, liquid-impermeable, this is the main contents of above-mentioned patent record.As core body, can use wood pulp, perhaps form laminated product that material constitutes etc. by 2 tissue papers and the hydrogel between these 2 tissue papers.
In addition, disclose a kind of sanitary towel in the special fair 6-38815 communique, wherein, be coated with the covering of one deck liquid permeability above the absorber, then be coated with the ventilative but liquid-tight barrier layer of one deck below it.The sanitary towel of Gou Chenging like this can use in this technical field known habitual comminution pulp therefore can think that this sanitary towel has breathability on its thickness direction as the absorber of sanitary towel.
The thin sanitary towel of record in above-mentioned U.S. Pat 4,950,264, it is higher that contained hydrogel forms the amount ratio of material in its core body, so the rigidity of this sanitary towel increases thereupon, thereby impair the adaptation of sanitary towel and skin.This material is normally hard, fine particle, and the core body that the containing ratio of this material is high must pressurize, and preferably pressurizes under moisture state, so that it becomes bulk, if do not pressurize, just is difficult to make it to keep the shape of core body.In addition, the polyethylene film that uses as the water proof damp course can send ear-piercing sound when operating this sanitary towel.
Disclosed sanitary towel in the fair 6-38815 communique of spy, in case liquid permeability cover layer wherein or absorbent body body fluid, at this moment the air-vent that forms in cover layer or absorber is just stopped up by body fluid, thereby makes sanitary towel lose breathability on its thickness direction.
According to this situation, problem of the present invention provides a kind of good breathability of also keeping after absorb body fluids, and relatively Bao disposable humor absorbent article.
In order to solve above-mentioned problem, the invention provides a kind of disposable and liquid adsorption type wearing and articles for use, as its prerequisite, it is made of the surface layer of breathability, the inside layer of breathability and the breathability intermediate layer between this is two-layer.
Under above-mentioned prerequisite, the invention is characterized in that above-mentioned surface layer is a kind of body liquid absorptive nonwoven fabric of being made by hydrophilic fibre, wherein has the open-work that many apertures are 0.3～3mm; Above-mentioned the inside layer is a kind of nonwoven fabric of being made by the thermoplastic synthetic fiber of fiber number 1～8d; Above-mentioned intermediate layer is made of at interior multi-layer thermoplastic synthetic fibers nonwoven fabric the meltblown nonwoven fabric that comprises liquid block and breathability at least.
In a preferred embodiment of the invention, above-mentioned hydrophilic nonwoven fabric is the nonwoven fabric of cellulosic fibre system, this nonwoven fabric can be nonwoven (spunless) nonwoven fabric of being made by any material in Cotton Gossypii, paper pulp, artificial silk, the acetas, and the weight per unit area of above-mentioned cellulosic fibre nonwoven fabric is 15～70g/m 2Most above-mentioned adjacent open-works centre-to-centre spacing each other is in the scope of 1～10mm.In addition, the weight per unit area of above-mentioned meltblown nonwoven fabric is 10～30g/m 2
At length explain the present invention with the knickers liner as the example of disposable baby fluids absorbent garment having disposal securing means below, specify as follows.
Fig. 1 is the oblique view of knickers liner 1, and Fig. 2 is the sectional view that II-the II line is cut open along Fig. 1.It is t that knickers liner 1 has the inside 3, surface 2 to the thickness between the inside 3 that contact with the surface 2 of wearer's contact skin, medicated underpants when wearing, on the direction of thickness t, this knickers liner constitutes by surface layer 6, the inside layer 7 and between these intermediate layer 8 laminations between two- layer 6 and 7.
The weight per unit area of surface layer 6 is 15～70g/m 2, it is a kind of by hydrophilic fibre, and cellulosic fibre is preferably entwined together and the absorbency fabric that constitutes mutually, and the open-work 11 that to form a kind of aperture D on this fabric be 0.3～3mm is 1～10mm in adjacent open-work 11 mutual centre-to-centre spacing.This fabric has breathability by the effect of fibre gap, and the combined effect of the surface layer 6 that has formed open-work 11 on this fabric by its fibre gap and open-work 11 has breathability.Example as hydrophilic fibre has: Cotton Gossypii, paper pulp, artificial silk, acetas, and the surface of hydrophobic fibre carried out the known absorption of perspiration fiber that obtains after the hydrophilicity-imparting treatment etc., these fibers can be individually or are processed into fabric with mixing.As described fabric, forms such as nonwoven fabric, random fabric, parallel lines fabric can be arranged, but the form of nonwoven fabric preferably, the special preferably form of nonwoven nonwoven fabric, and, the direction that in use can the operating direction when making be knickers liner length is used, and uses Cotton Gossypii as fiber.Because Cotton Gossypii has the fibre length of about 10～50mm usually, therefore handle the nonwoven nonwoven fabric that the back obtains by this cotton fabric through the high-pressure injection current, lump together owing to twining, therefore have advantages of higher tensile strength, and can obtain to prevent the effect of fibre shedding in the mutual intricately of fiber.In addition, this nonwoven fabric has and is peculiar good skin feel of Cotton Gossypii and good absorbency.Open-work 11 on the surface layer 6 can form with known or well-known method, for example fabric is suppressed and formed with a pair of embossing roller, perhaps, fabric is layered on the support with many projections, use this fabric of high-pressure injection water flow jet then, the perisporium that makes the fiber of this fabric paste above-mentioned projection is arranged again, thereby forms open-work.
As the inside layer 7, can use a kind of is that the thermoplastic synthetic fiber of 1～8d makes by fiber number, and weight per unit area is 10～50g/m 2The sticking method nonwoven fabric of point.This nonwoven fabric adds in heating to be depressed, and its fiber fuses on dispersive each point each other, has formed some and has had 0.5～5mm 2The fusion points (not shown) of area, so the good permeability of this nonwoven fabric, tensile strength is big.At the fusion points place, fiber fuses each other and reaches filming, and the area of these fusion points accounts for 10～70% of the inside layer 7 gross area.Preferably these fusion points inside distribute on layer 7 the entire area equably, but under the condition of the breathability that hinders the inside layer 7 indistinctively, also can be distributed in specific part with laying particular stress on.
Intermediate layer 8 constitutes by application of anti-leakage layers 12, strengthening course 13 and cushion 14 are stacked in turn, wherein, application of anti-leakage layers 12 is used to prevent that strengthening course 13 is used to improve the tensile strength of application of anti-leakage layers 12 by the seepage of the inside layer 7 to surface layer 6, and cushion 14 is used to make liner 1 bulk, thereby makes its softness.Even the body fluid that is absorbed by surface layer 6 permeates to intermediate layer 8, application of anti-leakage layers 12 also can prevent or suppress the infiltration of body fluid, makes it can't reach the inside layer 7.As said application of anti-leakage layers 12, can use and a kind ofly make as raw material with thermoplasticity synthetic resin such as acrylic resins, its weight per unit area is 10～30g/m 2The meltblown nonwoven fabric.This nonwoven fabric has breathability required in practicality and can prevent or suppress the saturating liquid block that body fluid sees through when using as baby fluids absorbent garment having disposal securing means.When this nonwoven fabric was made with the meltblown fibers of a kind of fiber number below 1d, it just had the flexibility as cloth, can not send to resemble ear-piercing sound the plastic sheeting when bending.But, when this nonwoven fabric uses at the surface-coated material as general baby fluids absorbent garment having disposal securing means, do not have satisfactory tensile strength and rub resistance intensity usually.In order to improve the intensity of this nonwoven fabric, can be bonded together with strengthening course 13 and above-mentioned meltblown nonwoven fabric.As strengthening course, can use a kind of spunbonded type nonwoven fabric of the thermoplastic synthetic fiber's systems such as polypropylene fibre by fiber number 1～8d, the weight per unit area of this nonwoven fabric is 10～40g/m 2Cushion 14 be a kind of be the bulk nonwoven fabric that the composite fibre of crispaturaing of 1～8d is made by fiber number, its weight per unit area is 10～50g/m 2Example as the composite fibre that is suitable for has: shell core type composite fibre, parallel composite fiber etc.These composite fibres can be entwined together and/or entwine together by mutual fusion sometimes by mechanism.Nonwoven fabric under latter event can have good especially resiliency as knickers liner 1 time.
The inside layer 7, application of anti-leakage layers 12, strengthening course 13, cushion 14, the surface layer 6 that are in layer-by-layer state as shown in Figure 2 carry out the bonding of spaced point on their face that is bonded with each other, so that make it be unlikely the breathability that hinders each layer significantly.This bonding, can use binding agents such as hot melten type binding agent, in addition, can not use binding agent yet and make each layer carry out the melt bonded of spaced point each other.Be coated with binding agent 21 below the inside layer 7 under layer-by-layer state, following peeling paper 22 covering protections of then using of this binding agent 21.In order to make liner 1 keep and can fix from the state that dress is peeled off with medicated underpants, should be by spaced point coating adhesive 21, so that do not hinder the breathability of the inside layer 7.
Therefore the knickers liner 1 that so constitutes has breathability owing to be to be laminated by the mode of multi-layered gas-permeable layer according to the breathability of not damaging them on thickness direction.As the liner 1 of wearing usefulness, body fluid is absorbed by its surface layer 6 and remain on wherein.Each layer that is in surface layer 6 downsides made by hydrophobic thermoplastic synthetic fiber, and therefore, the body fluid that is absorbed by surface layer 6 almost completely can not shifted to intermediate layer 8 by surface layer 6.Certainly, when body fluid volume has been compared surplus with the liquid absorption of liner 1, or liner 1 is not particularly limited when being subjected to bigger pressure from health.
In surface layer 6, the aperture D of open-work 11 will be much larger than the gap between the cotton fiber that forms fabric, in a single day excretory body fluid flow into open-work 11, as long as at this moment be in the liquid absorption of the surface layer 6 around this open-work 11 state that do not reach capacity as yet, body fluid will be absorbed by the cotton fiber of open-work 11 perisporiums, thereby body fluid is disappeared from open-work 11.Because the below of open-work 11 is hydrophobic cushions 14, the body fluid that therefore can not take place in the open-work 11 are shifted to the inside of liner 1 by open-work 11, stop up the gap between the fiber in cushion 14 or the application of anti-leakage layers 12 and therefore hinder the problem of the breathability of above-mentioned each layer.This is because in case from open-work 11 disappearances, liner 1 just can remain on the breathability on the thickness direction again by the effect of this open-work 11 when body fluid.
Disposable baby fluids absorbent garment having disposal securing means of the present invention, except illustrated knickers liner, can also be as sanitary towel, incontinent person with inhaling the urine liner, sucking blood with uses such as liners.
Disposable baby fluids absorbent garment having disposal securing means of the present invention, owing to be to use the thin layer of a kind of absorbency and breathability as surface layer, stacked a kind of being weaved cotton cloth by thermoplastic synthetic fiber's manufacture-illegal made on this surface layer then, therefore have liquid block and breathability, so these article can become a kind of article of thin and breathability.
Since fiber bonding part melt bonded or that form by binding agent not on surface layer by cellulosic fibre, and use a kind of nonwoven nonwoven fabric, so the skin feel of these article is good, its absorbability is also good.
Because having some apertures on the surface layer is the open-work of 0.3～3mm, therefore drains the rear surface layer and also can keep air permeability and good when body fluid.
Owing to use the thin layer of meltblown nonwoven fabric, the ear-piercing sound that is produced in the time of therefore can not being emitted in the plastic sheeting that uses gas-permeable, liquid-impermeable as saturating liquid block.
Fig. 1 is the oblique view of knickers liner.
