[0040] ①Preparation of nano-zinc oxide finishing agent: heating zinc acetate dihydrate in a water bath at 80°C, stirring and dissolving in 5 times the volume or mass of absolute ethanol, cooling to obtain solution A; change the mass to zinc acetate dihydrate 1 / 20 lithium hydroxide monohydrate is dissolved in 10 times the volume or mass of absolute ethanol, and ultrasonic treatment is performed for 10 minutes to obtain solution B; under the state of strong stirring, slowly drip solution B into solution A to obtain nano zinc oxide finishing Agent stock solution
[0041] ②Preparation of copper sulfate finishing agent: Dissolve copper sulfate with a mass of 1 / 2 of zinc acetate dihydrate in an ethanol solution of 20 times the volume or mass at room temperature. The mass concentration of the ethanol solution is 10% to prepare copper sulfate Finishing agent stock solution;
[0042] ③Finishing of non-woven fabric: Take 2 parts volume of nano-zinc oxide finishing agent stock solution and ...
Example Embodiment
[0048] Examples:
[0049] The three-layer structure of this new rodent cushion is separately produced and processed, and finally formed by thermal bonding. This embodiment specifically follows the following steps:
[0050] (1) Diversion layer
[0051] Adopt the existing double-effect (surface hydrophilic, bottom surface water repellent) perforated non-woven three-dimensional guide layer material (polypropylene resin), the quantitative is 30-50g / m 2 . The material has a funnel-shaped structure with pores, and the surface tension of the liquid makes it oriented to infiltrate into it. When the liquid enters, the pores make the lower penetration resistance almost zero, increasing the infiltration volume; the infiltrated liquid is not easy to produce concentric circular diffusion. Instead, it falls into the water at a single point, directing the liquid vertically into the core layer.
[0052] (2) Absorbing core layer
[0053] The main raw materials for manufacturing the absorbent core lay...
