Non-woven fabric containing shell powder and having function of continuously releasing negative oxygen ions and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to a nonwoven fabric and a preparation method thereof, in particular to a nonwoven fabric containing shell powder and capable of continuously releasing negative oxygen ions and a preparation method thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. A new type of fiber product with soft, breathable and planar structure. The advantage is that it does not produce lint, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it has a cotton-like feel. It has been widely used in the automotive field . But staying in a confined space for a long time, people will feel dizzy. When we come to places such as forests, seasides and wate...
