TABLE 5.1

As can be seen from the above examples, the present invention can have excellent effects in sterilization, anion health care, and menstrual blood cleaning effects.

This is because the unidirectional conductive layer used in the present invention has a compression work of 0.5 to 1.0cN/cm²The filling power is 6-10 cm³The functional fiber material has proper elasticity, is matched with the microporous structure and the corrugated microporous structure to generate microcosmic bellows effect, causes local vacuum, converts the mechanical kinetic energy of a human body in the using process into the elastic potential energy of the functional material, and further evacuates the functional fiber material once and again to absorb menstrual blood actively. In addition, because each part of functional material fiber is a double-layer superposed hydrophilic layer and a hydrophobic layer, cell membranes such as red blood cells and the like in menstrual blood are hydrophilic, and like a fine-grained endometrium, the one-way flow guide layer structure provided by the invention has oleophilic property, a hydrophilic component and an oleophilic component can be actively absorbed by using the hydrophilic layer plus the bellows effect, and after the hydrophilic component and the oleophilic component are absorbed to a cavity, the oleophilic fine-grained substance is absorbed to the upper part of the cavity by the oleophilic layer, so that the hydrophilic substance enters the cavityThe step is guided and adsorbed to the strong adsorption core body of the core layer by layer.

Outside the preferred range of the present invention, however, the microscopic "bellows" structure may collapse or fail to create a partial vacuum.

In the aspects of sterilization and negative ions, because the modified chitosan and the functional ceramic powder are added in the fabric used by the invention, the chitosan has a three-dimensional space network structure, and after modification, hydrophilic groups can be provided to adsorb hydrophilic components, and more importantly, the three-dimensional structure is provided on the microcosmic aspect, so that conditions are created for the synergistic generation of the negative ions of the tourmaline and the ceramic powder. Meanwhile, the functional ceramic powder has the far infrared radiation effect and can provide the synergistic effect for the sufficient ionization of the tourmaline.

However, outside the preferable range of the present invention, there are problems such as particle agglomeration at a microscopic level and failure to produce a synergistic effect.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
