Specific embodiment
The protection of the present invention is taken non-woven fabrics and is at least made of upper layer non-woven fabrics, middle layer melt spraying non-woven fabrics, institute
The content for stating a diameter of 1~8 micron of single fiber in melt spraying non-woven fabrics is more than 50 weight %.Non-woven fabrics is taken for protection
The number of plies can be three-decker or three layers or more of structure.When the structure that non-woven fabrics is three layers or more is taken in protection
When, at least one layer of intermediate filter layer is overlapped for melt spraying non-woven fabrics, is bonded and obtains.Upper and lower surface layer non-woven fabrics ensures protection
Non-woven fabrics is taken with high intensity, what intermediate melt spraying non-woven fabrics ensured that protection takes that non-woven fabrics had prevents dust and good
Permeability.Accordingly, it is considered to air permeability and dust tightness, the preferably upper layer non-woven fabrics of non-woven fabrics is taken in protection of the invention
Clamp middle layer melt spraying non-woven fabrics.
The middle layer melt spraying non-woven fabrics of the present invention are formed by a diameter of 1~8 micron of single fiber, and its content is 50
More than weight %.It is excessively high to fiber performance requirements if the diameter of single fiber is less than 1 micron, manufacture difficulty can be increased, from
And cost is improved, and fiber is thinner, it is manufactured into finer and close during non-woven fabrics, permeability can be caused to decline；If single fiber is straight
If diameter is more than 8 microns, single fiber is excessively thick, may result in the surface layer aperture of melt-blown non-woven fabric layer and increases, saturating so as to cause dust
Crossing the amount of nonwoven layer increases, and shows that the arresting efficiency of melt-blown non-woven fabric layer is low, i.e., anti-dust performance is deteriorated.Consider and be produced into
Sheet and permeability form more preferable 4~8 microns of the diameter of the single fiber of middle layer melt spraying non-woven fabrics of the present invention.Strainability
During test, dirt generating means is linked in the upstream side of the specimen holder of 0 type round of fixed test sample, is linked in downstream side
Corpuscular counter（Japanese RION corporations）, can simulate people by adjusting equipment air quantity and wear protective garment made of the non-woven fabrics
When, under certain wind friction velocity, measure the anti-dust performance that non-woven fabrics is taken in the protection.
Forming the content of a diameter of 1~8 micron of single fiber of the middle layer melt spraying non-woven fabrics of the present invention must control
More than 50 weight % if content is less than 50 weight %, since thickness is uneven between fiber, may result in melt-blown non-woven fabric layer
Surface apertures it is inhomogenous, Aperture deviation is larger, so as to which the effect of high arresting efficiency be not achieved.The present invention is due to using average fibre
The dimension superfine fibre that diameter is small, distribution of fiber diameters is narrow is formed, and arresting efficiency and gas permeability are excellent.In view of diameter 1~8
Fiber content in micron range is higher, and the more stable fiber distribution more uniform, the better, and arresting efficiency is also higher, therefore is formed
The single fiber diameter of melt spraying non-woven fabrics is 1~8 micron of content preferably more than 80 weight %.
The adhesion amount of phosphoric acid ester antistatic agent is 0.3~1.2 weight % in the surface layer non-woven fabrics of the present invention.It was producing
Antistatic treatment is carried out to upper layer non-woven fabrics using the antistatic agent of phosphoric acid ester in journey, remaining in antistatic agent on a small quantity into
It is divided into surfactant, plays catalyst action, the substance contained in final non-woven fabrics obtained is phosphoric acid ester.Phosphoric acid ester is
The main component of antistatic agent, after collated, the hydrophilic group on molecule is arranged both facing to air side, forms a unimolecule
Layer conductive layer plays a part of to guide charge, reduces the resistance of nonwoven surface.Phosphoric acid ester is existed by the steam adsorbed in air
Surface forms one layer of conductive moisture film to reduce sheet resistance.If the adhesion amount of phosphoric acid ester in the non-woven fabrics is excessively high, resist
Electrostatic agent molecule has extra free molecule and exists other than enriching section, these free molecules are easily migrated to middle layer,
The chargeding performance of middle layer melt spraying non-woven fabrics can be influenced, so as to make the arresting efficiency hydraulic performance decline of the non-woven fabrics, it is difficult to trap
Fine particle；If the adhesion amount of phosphoric acid ester in the non-woven fabrics is too low, protection takes the antistatic effect of non-woven fabrics not
It is good, the specification value of sheet resistance is not achieved, can rub during use with other materials generates damage.In addition, work as antistatic agent
When concentration is relatively low, antistatic agent molecule is mainly present in amorphous area in a free form after material molding, and free is antistatic
Agent molecule is easy to surface migration, i.e., to shift to intermediate charged layer, be gradually reduced its chargeding performance.In view of the anti-of non-woven fabrics
The adhesion amount more preferable 0.5 of phosphoric acid ester in non-woven fabrics is taken in dirt, antistatic property and production cost, protection of the invention
~1.0 weight %.At present, antistatic agent is broadly divided into anionic species, cationic, nonionic class and both sexes class.Wherein, it is cloudy from
Subclass and nonionic class are generally used for preventing in band electric machining；Cationic and both sexes class are generally used for spinning, weaving breast
Comparison in agent ingredient is more.Although cationic and both sexes class antistatic agent to the strong adhesive force of material, thermal stability compared with
Difference, and there is the problems such as pollution, adsorbing metal ions.And the antistatic agent of anionic species, not only with excellent anti-charging property,
Also there is certain thermal stability.Therefore, antistatic agent preferred anionic type antistatic agent of the invention, anionic are antistatic
