The invention discloses a non-
woven fabric containing shell
powder and having a function of continuously releasing negative
oxygen ions and a preparation method thereof. The non-
woven fabric is characterized by being prepared from the following raw materials in parts by weight: 1 to 2 parts of shell
powder, 4 to 8 parts of nanometer
tourmaline powder, 1 to 2 parts of
quartz, 4 to 9 parts of
polylactic acid, 1 to 2 parts of
polyethylene glycol 200, 3 to 5 parts of
active carbon, 5 to 9 parts of peppermint essence, 1 to 3 parts of
olive oil, 50 to 70 parts of isotatic
polypropylene, 3 to 6 parts of diatomite, 1 to 2 parts of
sodium dodecyl sulfate, a proper amount of
sodium carboxymethyl cellulose and a proper amount of water. The nanometer
tourmaline powder is added into the non-
woven fabric, so that the effect of continuously releasing the negative
oxygen ions can be achieved; when the non-woven fabric is applied to automotive interiors, the internal space of an automotive can become clear, comfortable and refreshed; through use of the peppermint essence, a remarkable refreshing effect is achieved; the shell powder and the like are applied, so that the non-woven fabric is easy to prepare, and is low in production cost.
