[0040] ① Preparation of nano-zinc oxide finishing agent: heat zinc acetate dihydrate in a water bath at 80°C, stir and dissolve in absolute ethanol 5 times its volume or mass, and cool to obtain solution A; Dissolve 20% lithium hydroxide monohydrate in 10 times the volume or mass of absolute ethanol, and ultrasonically treat for 10 minutes to obtain solution B; in the state of vigorous stirring, slowly drop solution B into solution A to obtain nano-zinc oxide finishing stock solution;
[0041] ② Preparation 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 make copper sulfate Finishing agent stock solution;
[0042] ③ Finishing of non-woven fabrics: Take 2 volumes of nano-zinc oxide finishing agent stock solution, 1 volume of copper sulfate finishing agent stock solution, add 2000 volumes of d...
Embodiment
[0049] The three-layer structure of the new rodent bedding is produced and processed separately and finally bonded by heat. This embodiment is specifically carried out according to the following steps:
[0050] (1) diversion layer
[0051] Adopt the double-effect (surface hydrophilic, bottom surface water-repellent) perforated non-woven three-dimensional diversion layer material (polypropylene resin) existing on the market, with a weight of 30-50g / m 2 . The material has holes in a funnel-shaped structure, and the surface tension of the liquid makes it oriented to infiltrate into it. When the liquid pours in, the holes make the lower penetration resistance almost zero, and the infiltration amount increases; the infiltrated liquid is not easy to produce concentric circle diffusion. Instead, it falls into the water at a single point, directing the liquid vertically into the core.
[0052] (2) Absorbent core layer
[0053] The main raw materials for manufacturing the absorbent...
