あった。2. Description of the Related Art Conventionally, there are mainly the following three types of methods for imparting conductivity to a nonwoven fabric. Firstly, a method is known in which a non-woven fabric is subjected to electroless plating to deposit a specific amount of metal component. However, this method is disadvantageous in that the cost is high and the fibers constituting the non-woven fabric are limited to polyester fibers for the reason that chemical resistance is required, and it is not possible to meet various needs. The second method is a method of forming a nonwoven fabric from conductive fibers such as metal-plated fibers and heat-sealing fibers. However, this method has the drawbacks that the productivity is low, the cost is high, and the conductive property depends on the mixing ratio of the conductive fibers. The third method is a method of imparting conductivity by impregnating a non-woven fabric with a paint or resin mixed with a conductive substance such as metal powder. The paint used in this method has problems in working environment since it is mainly an organic solvent, and also has a drawback that the resistance value is hard to decrease. In this method, there is a problem that the permeability of the non-woven fabric formed between the fibers is deteriorated and the air permeability deteriorates. When this condition occurs, the porosity and flexibility are impaired and the features of the non-woven fabric are lost. was there.

In particular, the present invention relates to the conductive non-woven fabric having a surface electric resistance value of 20 kΩ / □ or less. The present invention also relates to the above method for producing a conductive non-woven fabric, which comprises coating the surface of a non-woven fabric made of organic fibers with an aqueous coating liquid containing conductive fine particles and a water-based curable epoxy resin, and then curing the epoxy resin.

Any of those mechanically joined by needle punching or the like and those joined by direct melting such as spunbond can be used. Preferred is a non-woven fabric of a type joined by an adhesive. The basis weight and thickness of the non-woven fabric may be freely selected depending on the use as the conductive non-woven fabric. For example, the basis weight is 30 to 150 g / m 2 , and the thickness is 25 to 500 μm, preferably 30 to 250 μm. However, the present invention is not limited to this.

しく、より好ましくは１５〜５０ｍμである。As the conductive fine particles that can be used in the present invention, fine particles of a metal or a conductive organic substance can be used. Among them, graphite or carbon black is particularly preferable in terms of workability and cost. Specific examples of graphite or carbon black include natural graphite, artificial graphite, furnace black, acetylene black, and Ketchin black. The conductive fine particles need to be uniformly dispersed on the surface of the non-woven fabric so that a conductive discontinuity does not occur. Therefore, it is preferable that the particles are as fine as possible. However, if it is too fine, the viscosity of the dispersion becomes too high when it is dispersed in a binder, so 10 to 200 mμ is preferable, and 15 to 50 mμ is more preferable.

があり、好ましくない。Since the conductive fine particles are fixed uniformly on the nonwoven fabric surface, the conductive fine particles are fixed on the nonwoven fabric surface in a state of being uniformly dispersed in the binder. As the binder, various synthetic resins or natural resins can be used, but they have conductivity, chemical resistance, adhesiveness to non-woven fabric and conductive fine particles,
A curable epoxy resin is particularly preferable in that it has appropriate flexibility. The epoxy resin may be either a one-component type or a two-component type, but from the viewpoint of workability, a thermosetting type epoxy resin having a long pot life is more preferable. Epoxy resin is preferably used as an aqueous dispersion because it can prevent the film formation in the mesh of the non-woven fabric when it is used in a low viscosity and low state. Here, low viscosity is 1000
cps or less, especially 100 to 500 cp
It is preferably about s. When using a coating liquid in which conductive fine particles are dispersed in a resin other than an epoxy resin, such as a curable acrylic resin or a urethane resin, water resistance and chemical resistance are inferior to those of an epoxy resin, and there is a problem that the use is limited. Yes, it is not preferable.
