Non-woven material is also known as non-woven cloth, nonwoven fabric, supatex fabric, adhesive-bonded fabric or non-woven fabrics.Non-woven It is a kind of fabric that textile cloth is not required and is formed, is directly to pass through various fibre webs using high polymer section, staple fiber or long filament The new type of fibrous product with a soft, breathable and planar structure that manufacturing process and concretion technology are formed.Due to non-woven material Have the characteristics that technological process is short, speed of production is fast, yield is high, cost is low, purposes is wide, raw material sources are more, no matter in space flight skill Many fields such as art, environment protection treating, agricultural technology, health-care medical or daily life, non-woven new material have become A kind of more and more extensive staple product.
But non-woven material of the prior art, such as viscose non-woven material, needled punched nonwoven material, heat seal are non- Weaving material etc., when in use easily because friction produces electrostatic problem.So it is fine that antistatic is added generally in non-woven material Dimension, antistatic fiber generally uses conductive fiber and antistatic fibre, and the antistatic principle of antistatic fibre is anti-by adding Electrostatic agent improves the hydrophilic hygroscopicity on its surface so as to increasing electric conductivity, though its own, which has, improves the antistatic of fiber and fabric Effect, but since its antistatic property is mainly to be realized by the moisture in air is absorbed, its antistatic effect and environment Humidity it is closely related, when ambient humidity is very low, its antistatic effect is very weak or even disappears, and antistatic fibre is washable Property and persistence have much room for improvement, therefore the antistatic non-woven material that the fiber that with the addition of antistatic additive in the prior art is prepared into Material, its antistatic property persistence are poor.
The content of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of anti-electrostatic nano fiber non-woven material Material, has lasting antistatic property, hydrophilicity is excellent.
For this purpose, the present invention uses following technical scheme：
