Abstract

The utility model relates to a skin contacting reverse osmosis-prevention sanitary article mesh shell fabric with a dry surface. The utility model is characterized in that the utility model is composed of a hydrophobic fiber layer 1 and a modified hydrophilic macromolecular material layer 2 which are pressed or bonded into an integral whole; one-way seepage holes are processed from the hydrophobic fiber layer to a macromolecular coating layer. The seepage holes can be in the shape of arc, or cone, or oval, or circle, or polygon, can form warp-weft arrangement and staggered arrangement, and can form patterns by changing the shape and the size of the seepage holes. Because the utility model has the advantages of one-way seepage, reverse osmosis prevention, quick diversion, complete seepage, moisture insulation, good ventilation performance, dry and comfortable surface, high air permeability, good skin contacting performance and no allergic reaction in use, the utility model is particularly suitable for the shell fabric of sanitary articles, such as sanitary towels, napkins, etc.

Description

The hygienic article netty shell fabric that dry and comfortable, the close skin in surface, reverse-osmosis-prevention leak

This utility model relates to the hygienic article material, be a kind ofly have that the surface is dry and comfortable, breathability is strong, skin-friendly good, every the characteristics wet, that reverse-osmosis-prevention leaks, be applicable to the netty shell fabric of hygienic article such as sanitary towel, sanitary pad, baby diaper, medical bed mattress.

Existing hygienic article is as the lining of sanitary towel, baby diaper, generally all with non-woven fabrics or PE making hole film.Make lining with non-woven fabrics, its weak point is: sepage speed is slower, and sepage is not thorough, and institute's sepage body easily returns and is seeped into the surface, influences result of use; Make lining with the PE making hole film, its weak point is: plastic sense is strong, skin-friendly is poor, flexibility is poor, in use, easily causes allergic reaction.

The purpose of this utility model just provides surperficial dry and comfortable, the close skin that a kind of sepage is very fast, sepage complete, nothing allergy is reacted, breathability is strong, the hygienic article netty shell fabric that reverse-osmosis-prevention leaks.

The purpose of this utility model realizes by following structure, that is: the hygienic article netty shell fabric that leaks of dry and comfortable, the close skin in a kind of surface, reverse-osmosis-prevention is characterized in that: by the hydrophobic fiber layer with through the hydrophilic high molecular material layer of modification through pressing or bondingly constitute; Be processed with unidirectional liquid-leadage hole by hydrophobic fiber course polymeric coating layer.

This utility model is owing to adopt the hydrophilic high molecular material layer of modification, and by the hydrophilic that macromolecular material has, energy is the drain penetrating fluid rapidly, and simultaneously, this floor height molecular material plays again every wet effect.

This utility model utilizes hydrophobic fiber layer and hydrophilic high molecular material coating poor to the surface tension of water--the rapid draining fluids of hydrophilic high molecular material layer, the hydrophobic fiber material layer repels liquid, thereby have unidirectional sepage function, and infiltrate liquid that can not and return the seepage phenomenon.

This utility model compared with prior art have skin-friendly good, every wet, ventilative, the surface is dry and comfortable, sepage rapidly, back infiltration, do not have advantage such as irritated reaction.

Structure of the present utility model can further specify by the embodiment that accompanying drawing provides.

This utility model has following accompanying drawing:

Fig. 1 is a structure cutaway view of the present utility model;

Fig. 2-4 is the mesh figure of example 1 unidirectional sepage of the present utility model;

Fig. 5-7 is the mesh figure of example 2 unidirectional sepages of the present utility model;

Fig. 8,9 is the mesh figure of example 3 unidirectional sepages of the present utility model;

Figure 10,11 is for being the mesh figure of example 4 unidirectional sepages of the present utility model;

Figure 12-1 is the mesh figure of example 5 unidirectional sepages of the present utility model;

Figure 14-16 is the mesh figure of example 6 unidirectional sepages of the present utility model;

Figure 17,18 is the mesh figure of example 7 unidirectional sepages of the present utility model.

Referring to accompanying drawing 1, the hygienic article netty shell fabric that surperficial dry and comfortable, the close skin shown in the figure, reverse-osmosis-prevention leak is characterized in that: by hydrophobic fiber layer 1 with through the hydrophilic high molecular material layer 2 of modification through pressings or bondingly constitute; Be processed with unidirectional liquid-leadage hole by hydrophobic fiber course polymeric coating layer.

Referring to accompanying drawing 2-4, in the present embodiment, the net of unidirectional sepage also 3a is the recessed road of an arc mesh, and liquid is flowed out along bottom opening place, both sides, the recessed road of arc, oppositely then fluid stopping, i.e. check valve by the recessed road of arc.

Referring to accompanying drawing 5-7, in the present embodiment, the mesh 3b of unidirectional sepage is the taper mesh of liquid from big mouthful of inflow, osculum outflow, reverse fluid stopping.

Referring to accompanying drawing 8,9, in the present embodiment, the mesh 3c of unidirectional sepage is the polygon mesh, the destructible surface tension of liquid, thus make fluid seepage rapid.

Referring to accompanying drawing 10,11, in the present embodiment, the mesh 3d of unidirectional sepage is a diamond-shaped meshes.

Referring to accompanying drawing 12,13, in the present embodiment, the mesh 3f of unidirectional sepage is the circular hole that size dislocation inequality is arranged.

Referring to accompanying drawing 14-16, in the present embodiment, the mesh 3 of unidirectional sepage is the recessed road of an arc mesh, dislocation arrangement between row and the row between the recessed road of the arc mesh.

Referring to accompanying drawing 17,18, in this enforcement, the mesh 3e of unidirectional sepage is a big or small ellipse garden vertebra shape, and closure function can be played in the both sides in little ellipse garden, therefore, can leak i.e. check valve effect by reverse-osmosis-prevention to liquid.

Above-mentioned unidirectional sepage mesh of the present utility model can be the longitude and latitude proper alignment on lining, also can be dislocation arrangement, and can become the herringbone proper alignment again, and various patterns are formed in the hole that also can be different apertures.

What this utility model was applicable to hygienic article such as making sanitary towel, sanitary pad, baby diaper, medical bed mattress touches the skin lining.
