Embodiment 1
[0040] A kind of manufacture method of the net cloth that is used for bedding, its concrete steps are:
[0041] 1. Preparation of spinning modifier for bedding
[0042] Treat the tea waste residue in hydrogen peroxide with a mass fraction of 2% at 85-95°C for 20-60 minutes to oxidize the tea waste residue, filter and wash, then heat-treat with 1.5-3.5mol / L nitric acid solution at 80-105°C for 35 minutes ~50min to acidify and activate the oxidized tea waste residue, then add selenium element to react the selenium element with nitric acid, and generate uniform selenium dioxide on the surface of the acidified tea waste residue. 53KHz, the ultrasonic function is 70%, the stirring speed is 1100r / min, and the amount of selenium added is 15% of the mass fraction of tea waste residue, the reaction temperature is 50-100°C, and the reaction time is 40-120min. After the reaction, filter The tea waste residue is then washed with ethyl acetate, and then the tea waste residue loaded with s...
Embodiment 2
[0063] A kind of manufacture method of the net cloth that is used for bedding, its concrete steps are:
[0064] 1. Preparation of spinning modifier for bedding
[0065]Treat the tea waste residue in hydrogen peroxide with a mass fraction of 6% at 85-95°C for 20-60 minutes to oxidize the tea waste residue, filter and wash it, and then heat-treat it with 1.5-3.5mol / L nitric acid solution at 80-105°C for 35 minutes ~50min to acidify and activate the oxidized tea waste residue, then add selenium element to react the selenium element with nitric acid, and generate uniform selenium dioxide on the surface of the acidified tea waste residue. It is 53KHz, the ultrasonic function is 70%, the stirring speed is 1100r / min, and the amount of selenium added is 25% of the mass fraction of tea waste residue, the reaction temperature is 50-100°C, and the reaction time is 40-120min.
