Detailed Description

Example 1

Referring to fig. 1 to 3, the super-breathable incontinence pad of the present embodiment includes a skin-friendly dry layer 1, a liquid guiding layer 2, a wrapping absorption layer 3, a super-breathable leakproof bottom film 4 and a release peel layer 5.

In this embodiment, the skin-friendly dry layer 1 is made of super-soft hydrophilic hot air non-woven fabric or hydrophilic spun-bonded non-woven fabric. This super gentle non-woven fabrics top layer can not appear amazing phenomenon with human shank contact friction, promotes product use comfort.

The diversion liquid layer 2 is made of hydrophilic hot air non-woven fabric with the basis weight of 30-50 gms, and the main purpose of the diversion liquid layer is to guide the flow direction of urine and enable the urine to quickly penetrate into the coating absorption layer 3 along the direction of the diversion layer.

The coated absorption layer 3 adopts a wood pulp layer which is wrapped by toilet paper and contains SAP or a composite core body with high absorption function. Because the inner space on wood pulp layer and compound core layer is big, the urine is when permeating this layer, and high absorptivity resin SAP can absorb the urine rapidly and store to firmly lock inside SAP, in the use, the motion or the friction also can not have the urine and reverse the seepage out, and the user can not feel moist, promotes the comfort level.

The ultra-breathable leakage-proof carrier film 4 in this embodiment includes a water-repellent SMS nonwoven fabric 42 and a sub-nano meltblown 41 disposed on the upper portion thereof. The sub-nanometer melt-blown fabric 41 and the water-repellent SMS non-woven fabric 42 are compounded through hot melt adhesive. The water-repellent SMS non-woven fabric is formed by hot rolling two layers of spun-bonded non-woven fabrics and one or more than two layers of melt-blown fabrics arranged between the two layers of spun-bonded non-woven fabrics, namely SMS, SMMS and SMMMS. However, it should be noted that the meltblown M layer may be formed into multiple layers as required, and the higher the basis weight, the harder the material, and the better the liquid leakage prevention effect, but when the meltblown M layer is applied to a product, the softness of the whole product may be reduced, and the comfort level of a user may be reduced.

The water-repellent SMS nonwoven fabric 42 has a basis weight in the range of 10 to 20gms. The basis weight of the sub-nanometer meltblown 41 is 16-30 gms, and the sub-nanometer meltblown 41 is prepared from superfine fibers with the diameter of 600 nm-2 μm through a melt-blowing process. The superfine fiber material has a compact fiber structure, good air permeability and water repellency, and the density of micropores is less than that of urine, so that urine cannot leak, and the effects of air permeability and leakage prevention can be effectively achieved. It should be noted that although the SMS water-repellent nonwoven fabric has a certain water pressure resistance and a good liquid barrier property, the SMS water-repellent nonwoven fabric can not provide a sufficient anti-seepage protection effect for a user by directly using the SMS water-repellent nonwoven fabric as a base film, so that the SMS water-repellent nonwoven fabric is combined with the sub-nanometer meltblown fabric 41 to form a leakage-proof base film with a better anti-seepage protection effect and super-breathability, and the SMS water-repellent nonwoven fabric has a good practical application effect.

The super ventilative incontinence pad of this embodiment the dry and comfortable layer of close skin 1, water conservancy diversion liquid layer 2, cladding absorbed layer 3 and super ventilative leak protection basement membrane 4 are all formed through the bonding of hot melt adhesive 6 between two liang of adjacent layers.

Release peel ply 5 adopts special gum 7 to set up in the bottom of super ventilative leak protection basement membrane 4, and the incontinence pad of being convenient for is fixed, and special gum is peeled off from the clothing after easily using the product.

Example 2

Referring to fig. 4, the super-breathable sanitary napkin of the present embodiment has the same structure as the super-breathable incontinence pad body, but is different in that a water repellent nonwoven leakage-proof side edge 11 is provided on the outer peripheral side of the upper surface of the uppermost skin-friendly dry layer 1 for better preventing the problem of side leakage.

In this embodiment the leak protection side 11 adopts water repellent hot air non-woven fabrics or water repellent spunbonded nonwoven fabrics, the basis weight is 15-30gms, its main function is to guarantee that the side leakage can not take place in both sides after urine falls from the top layer and permeates to the water conservancy diversion liquid layer 2, promotes the comfort level.

Certainly, the sanitary product of the utility model can also be disposable sanitary products such as a comfortable cushion, a water absorption towel, a paper diaper and the like.

The utility model discloses super ventilative leak protection basement membrane is through setting up sub-nanometer melt-blown material on water repellency SMS non-woven fabrics, utilizes the strong characteristic of sub-nanometer melt-blown fiber structure compactness, makes this basement membrane micropore density be less than urine density, and water repellency is good, can not the seepage urine, but the gas permeability is excellent, effectively realizes ventilative waterproof effect.

The utility model discloses super ventilative health goods has replaced traditional PE curtain coating membrane and ventilative curtain coating membrane through utilizing super ventilative leak protection basement membrane, can promote the air permeability of nursing product in the use, makes its long-time back of using, and the surface can not feel sultry moist yet, and is ventilative dry and comfortable, lets the user wear the experience sense and promote by a wide margin during leaking urine. And the dried product can also inhibit the breeding and fission of certain bacteria, so that the breeding and fission rate of the bacteria is greatly reduced. The utility model discloses super ventilative health goods is a rational in infrastructure, uses soft comfortable, the absorption performance and the more excellent novel light health care product of air permeability, and the practical application is effectual, and easy degradation, friendly to the environment.

The above description is only for the preferred embodiment of the present invention, and not intended to limit the present invention in any way, and those skilled in the art can make various modifications, equivalent changes and modifications using the above-described technical content, all of which fall within the scope of the present invention.
