Above-mentioned back layer also can comprise the plasticizer as glycerols, and its weight and is best with 7% between back layer gross weight 5%～20%.
The thickness of back layer generally is no more than 100 microns, and best thickness is about 20 microns.
Above-mentioned imbibition core is mainly made by alginic acid fiber, and the imbibition core can be utilized small amount of moisture, and itself and back layer are bonded together.Should be noted that since back layer have can complete inherent character soluble in water, therefore, when utilizing moisture to make its produce adhesive effect, can only use atomic few deal, in order to avoid cause back layer to be disintegrated.The method of utilizing moisture that it is best is that atomizing adds water.
Also can be enclosed with a top layer on the imbibition core, the top layer should suitably be carried out in biological decomposition or the same water soluble with back layer.
For further control back layer in the higher torrid zone of relative humidity and temperature or the reliability under the subtropical environment, back layer can be made into the laminar body with discontinuity layer, the laminar body of arranging as pattern.
The position is more stable in use in order to make product, can adopt modes such as impression overleaf laminar surface form identical coarse or convex-concave surface.
Above-mentioned back layer can also adopt as materials such as basic cellulose, hydroxy-methyl cellulose and well-proportioned calcium salt and sodium salt alginic acid in ethyl cellulose, the methyl hydroxyl and make.
In view of both can having stoped the viscosity human body drainage of high protein content, above-mentioned water dispersed body fluid absorbing synthetic product oozed out outside the sintetics, can promptly be dissolved in the water fully again when throwing aside in drainage after this product uses simultaneously, therefore this absorption composite is applicable to as feminine hygiene articles, breast pad and wound treatment etc.
The invention has the beneficial effects as follows: both can stop the viscosity human body drainage of high protein content to ooze out outside the sintetics because body fluid of the present invention absorbs sintetics; can promptly be dissolved in the water fully when after this product uses, throwing aside simultaneously in drainage; thereby can not give with after throw aside and bring environmental effect; eliminated this product with after throw aside thing transport and bury related biohazard; and forever throw aside the place owing to need not be deposited in, therefore can reach the purpose of protection environment better.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the cross-sectional view of sanitary towel of the present invention;
Fig. 2 is the back layer plane graph of sanitary towel shown in Figure 1;
Fig. 3 is the cross-sectional view of second kind of sanitary towel of the present invention;
Fig. 4 is the cross-sectional view of another kind of back layer structure.
The specific embodiment
With reference to Fig. 1, Fig. 2, one of them ingredient of sanitary towel shown in the figure is an imbibition core 2, this imbibition core 2 is imbibition pads, material with paper stock or carboxymethyl cellulose absorbability extra-heavies such as (carboxymcthylcellulose) is made, the imbibition pad is sandwiched between net shape skin 1 and the back layer 3, and imbibition core 1 sticks on the back layer 3, and the thickness of this sanitary towel is no more than 100 microns.
On layer 3 surface discontinuous top layer 4 of waterproof is to a certain extent arranged overleaf, can strengthen the influence that back layer opposing high humility and temperature are brought.As shown in Figure 2, discontinuous top layer 4 is that a criss-cross is arranged laminar body, and it can allow back layer 3 thin film expose regularly.
With reference to Fig. 3, Fig. 4, imbibition core 2 can use alginic acid fiber 5 to be attached on the thin film, or make with the material of absorbability extra-heavies such as carboxymethyl cellulose, or make imbibition alginic acid fiber pad, be fixed between top layer and the back layer, but when using these imbibition cores, should be noted that it can be kept perfectly, and can be disintegrated when abandoning when dashing.In addition, make other material of imbibition core, can also comprise starch system thin slice or Rhizoma Solani tuber osi fiber etc.
With reference to Fig. 4, the back layer thin film can adopt the method for stamping manufacturing, in manufacture process, hydrolysis degree is mixed in water at 90%～95% polyvinyl alcohol resin and plasticizer such as glycerol, be stamped in then on the coarse or rough surface, for example the production band in the production line etc. is produced to carry out full-automation, existing its surface texture of the thin film that adopts this method to make need not impress operation in addition.As mentioned above, use stamped method that back layer thin film 3 is made male and fomale(M﹠F) 6, the export-oriented surface as sanitary towel helps it and is close on the underwear of user, thus need not or other binding agent capable of reducing using, with the fixing position of sanitary towel.
The periphery of sanitary towel's net shape skin 1, can utilize heating power and moisture or binding agent, be glued together with back layer 3, adhesive therefor should belong to water dispersible, because back layer 3 promptly is with viscosity after spraying small amount of moisture, therefore can utilize its this characteristic as the adhesive means between net shape skin 1 and the back layer 3, these means not only meet cost benefit, manufacturing process is simple, more can reduce must dissolve when synthetic products is thrown aside or dispersive ingredient number.
It is excessive that the material of making back layer 3 can prevent that the body fluid of discharging from seeing through back layer, for embodying these characteristics of the present invention, adopting thickness is that 20 microns, hydrolysis degree reach 95% polyvinyl alcohol film and test (used polyvinyl alcohol is formed by polyvinyl acetate (polyvinylacetate) and remaining second vinegar (acetyl) group material hydrolysis), and the result shows that this thin film can effectively stop the menses outflow of 10 milliliters of test volumes; On the other hand, single dripping just is enough to the molten thin film of wearing, and causes a hole in the above.
Get 20 micron thickness, the thin film that size is fit to manufacturing sanitary towel carries out soluble test.The temperature of test when carrying out is 25 ℃, thin film be placed into fill 350 ml waters experiment with beaker after, in not stopping the water that is stirred, just accuse in 25 seconds and disintegrate, disperse in 42 seconds, and dissolving fully in 99 seconds.When the water temperature that adopts was higher, the dissolution velocity of thin film was faster.
More than be to concrete introduction of the present invention, but the present invention still has a lot of other methods to be embodied, comprise and use polyvinyl alcohol material in addition to make back layer.When body fluid of the present invention absorbed the use of composite aspect sanitary towel, core 2 was also nonessential with top layer 1 or other packaging material parcel, also can directly stick on the back layer 3 simply simultaneously.
Body fluid absorption composite of the present invention can also be suitable for the use at aspects such as breast pad, wound treatments.
Though, synthetic products material therefor of the present invention preferably can all carry out biological decomposition or dissolve in water, but according to basic demand of the present invention, as long as back layer has certain water solublity, product is abandoned behind Waste Water Treatment (for example toilet bowl washes out it at home) can be disperseed rapidly to get final product.
