Nonwoven fabric with performances of toughening and retarding flame and capability of releasing negative oxygen ions and preparation method of nonwoven fabric

Abstract

The invention discloses a nonwoven fabric with performances of toughening and retarding flame and capability of releasing negative oxygen ions and a preparation method of the nonwoven fabric. The nonwoven fabric is characterized by being prepared from the following raw materials in parts by weight: 2 to 4 parts of nano-crystalline cellulose, 4 to 8 parts of nano tourmaline powder, 1 to 2 parts of micropowder silica gel, 5 to 10 parts of polylactic acid, 1 to 2 parts of polyethylene glycol 200, 3 to 5 parts of activated carbon, 4 to 8 parts of herba menthae essence, 1 to 2 parts of magnesium hydroxide, 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 carboxymethyl cellulose sodium and a proper amount of water. According to the nonwoven fabric disclosed by the invention, the nano tourmaline powder is added in the nonwoven fabric, so an effect of continuously releasing the negative oxygen ions can be realized; when the nonwoven fabric is applied to automotive interiors, a space in an automobile can become cool, comfortable and refreshed; by matching with the herba menthae essence, a remarkable refreshing effect is realized; by matching with the added nano-crystalline cellulose and the magnesium hydroxide, a target product is endowed with the functions of toughening and retarding flame.

Description

technical field [0001] The invention relates to a non-woven fabric and a preparation method thereof, in particular to a toughened and flame-retardant non-woven fabric 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 ...
