[0043] In other embodiments of the present application, in order to enable the mask 2 to have a reminder function for different use time periods, the mask 2 is provided with at least two of the above-mentioned logos 100, and at least two of the above-mentioned logos 100 are provided with opaque high moisture-absorbing cushions of different thicknesses. release layer 102, so that the corresponding signs 100 have different color development times when wet. The above-mentioned at least two signs 100 are arranged at intervals along the height direction of the mask 2 between the hydrophilic layer and the melt-blown layer. Exemplarily, for example, the wet color development time of one logo 100 is 30 minutes, and the wet color development time of the other logo 100 is 4 hours, and the colors of the wet color development of the two logos 100 are different, for example, the exemplary The logo 100 with a color development of 30 minutes when it is wet is blue; the color of the logo 100 ...
Embodiment 1
[0049] The preparation process of the irreversible display logo in this example is: sodium carboxymethyl cellulose 1g, CaCO 3 1g, SiO 2 5g, 43g of water, mixed with high-speed shearing and stirring evenly, passed through 150-mesh, 120-mesh, and 80-mesh screen frames and printed them in strips on the surface of PP non-woven fabrics, and dried at 80°C to form a thickness of 0.8μm , 1.2μm, and 2.0μm superabsorbent and slow-release layers, and then apply water-soluble red pigments on the surface of the superabsorbent and slow-release layers, and finally cover the pigments with plastic films to form irreversible display marks, and then irreversible color-developed marks of different thicknesses It is prepared into a strip shape with a width of 3mm in turn. During the preparation process of the mask, three kinds of irreversible color-developing marks are placed between the melt-blown layer and the skin-friendly layer in sequence. Through experimental test and comparison, it can be...
Embodiment 2
[0051] The preparation process of the irreversible display logo in this example is: 0.8g of hydroxyethyl cellulose, CaCO 3 1g, kaolin 5g, water 43g, mixed with high-speed shearing and stirring evenly, passed through 160-mesh, 120-mesh, 80-mesh screen frames and printed them in strips on the surface of PP non-woven fabrics, and dried at 80°C to form thicknesses. 1μm, 2μm, and 3μm superabsorbent and slow-release layers, then apply water-soluble blue pigments on the surface of the superabsorbent and slow-release layers, and finally cover the pigments with plastic films to form irreversible display marks, and then irreversible color-developed marks of different thicknesses It is sequentially prepared into a rope shape with a width of 5mm. During the preparation process of the mask, three kinds of irreversible color-developing marks are placed between the melt-blown layer and the skin-friendly layer in sequence. Through experimental test and comparison, it can be concluded that th...
