The method for making of a kind of absorber of the present invention comprises following step: (1) is dissolved in diluted acid with the chitosan powder earlier, to form the solution of chitosan; (2) on the layer of cloth that has completed, spray the solution of this chitosan in the mode of spraying.
Chitosan of the present invention claims chitosain again; it is the general name by the product of the high-molecular weight chitin of the natural biological that extracts in Crusta Penaeus seu Panulirus, Carapax Eriocheir sinensis or squid, the Os Sepiae behind deacetylate; it has free amido; the deacetylate degree is 65%～99%, and is the most common with 70～90%.
Chitosan powder in step of the present invention (1) is dissolved in the diluted acid process, and the chitosan content of powder is preferably 0.5～3wt% in the control solution between 0.05～15wt%; And adjust the solution pH value between 1.0～7.5, be preferably 4.0～5.5.Diluted acid of the present invention for example can be acetic acid, but is not limited only to this.
Owing in the environment of slant acidity, be easier to suppress the growth of antibacterial, and because of the content of chitosan can be different with its functional group's who has difference.The present invention mainly finishes the interpolation program of chitosan in the mode of spraying, the amount that is controlled at the described chitosan solution of spraying on the layer of cloth is 1～200g/cm
2, be preferably 10～15g/cm
2Account for 0.01%～3% of whole absorbent body total amount, so the amount of the chitosan that contains in every diaper seldom, still has spatial absorbtivity more than 97% at least, need not to use drying program for this reason, and only when needs, carry out drying with light or in modes such as ultraviolet and drying bakers just now.No matter above that a kind of mode can both obtain spraying the absorber that chitosan is arranged.
After step of the present invention (2) is finished, optionally can increase another drying steps so that form a protective film on the layer of cloth.
Reach technology, means and the effect that the predetermined purpose of the present invention is taked for further understanding, the present invention is described in detail below in conjunction with a preferable feasible embodiment and conjunction with figs..
