ができる。(Means for Solving the Problems) The object of the present invention described above is to contain 3 to 15% by weight of short carbon fibers and 20 to 70% by weight of short synthetic fibers, based on the total weight. A mixture containing wood pulp and a binder in the remainder was made using a wet paper making method.
The paper is made to a weight of 50 g/m 2 or less, is manufactured without applying heat or pressure that would inhibit the protrusion of the carbon fibers, and the short carbon fibers are uniformly dispersed, with 50 tips. / cm2 or more protrudes from the surface of the paper, has a half-life of 5 seconds or less, and has a frictional charging voltage.
This can be achieved by using abrasion-resistant static electricity neutralizing paper obtained by laminating one type of fabric selected from knitted fabrics, woven fabrics, or nonwoven fabrics on one side of static electricity neutralizing paper that has a voltage of 40 V or less.
本発明に適用する静電気中和紙の特異な点は、

突出させ、これによつて半減期が５秒以下で、か
つ摩擦帯電圧が40V以下である静電気特性を付与
したことである。 The unique features of the static neutralizing Japanese paper applied to the present invention are:
As mentioned above, specific amounts of short carbon fibers, short synthetic fibers, wood pulp, and a binder are blended, and a large number of short carbon fibers are made to protrude from the paper surface, thereby reducing the half-life to 5. The electrostatic property is that the frictional charging voltage is less than 40V.
すなわち、本発明は、炭素繊維の短繊維を紙表
面に多数突出させたため、該炭素繊維の先端から
コロナ放電をして静電気を中和するものである。 That is, in the present invention, since a large number of short carbon fibers are protruded from the paper surface, corona discharge is generated from the tips of the carbon fibers to neutralize static electricity.

するのである。 Assuming that the currently charged object has a positive charge, when this object is brought close to the static electricity neutralizing paper, an opposite negative charge will be induced in the carbon fibers in the static electricity neutralizing paper. . In other words, ions are created using the electrostatic energy of a charged object. When the - charges collected on the static electricity neutralizing paper move away and move towards the +-charged area and cause a corona discharge, the + and - charges combine and are neutralized.
Static electricity is safely removed. In reality, this phenomenon is repeated instantaneously and continuously to remove static electricity.

り好ましい。 In the present invention, the short fiber content of the carbon fiber is 3 to 15% by weight, but if the short fiber content of the carbon fiber is less than 3% by weight, the desired electrostatic properties cannot be obtained. %, the effect of improving the electrostatic properties is saturated and the manufacturing cost increases. The carbon fiber short fiber content is more preferably 5 to 10% by weight.
本発明で用いる炭素繊維の短繊維の単繊維繊度

より好ましい。 The carbon fiber short fibers used in the present invention preferably have a single fiber fineness of 1 to 5 d, a fiber length of 3 to 6 mm, and preferably have no crimp.
In addition, from the viewpoint of electrostatic properties, carbon fibers manufactured from acrylonitrile polymer fibers are more preferable.

リエステル繊維が好ましい。 In the present invention, the short fiber content of the synthetic fiber is 20 to 70% by weight, more preferably 40 to 50% by weight. If the short fiber content of the synthetic fibers is less than 20% by weight, the paper obtained will be hard and have reduced strength, and if it exceeds 70% by weight, paper-making properties will be reduced. In addition, the short fibers of synthetic fibers have a single fiber fineness of 1 to
5d, the fiber length is 3 to 6 mm, and preferably has no crimp. If the fiber length exceeds 6 mm or if the fibers are crimped, the fibers become entangled, resulting in poor dispersion and poor papermaking, which is not preferred.
Further, fibers having a length of less than 3 mm are not preferred because the strength of the paper decreases. Note that polyester fiber is preferable as the synthetic fiber.

効である。 In the static electricity neutralizing paper used in the present invention, 50 or more carbon fiber tips protrude above the surface of the paper. In addition, the protrusion length is
It is sufficient that the protrusion just barely touches the surface of the paper, and preferably about 0.01 to 1.0 mm is sufficient. This is effective for discharging static electricity in the air from the tips of the carbon fibers and exhibiting the static electricity properties of the static electricity neutralizing paper.

熱、加圧はしないようにすることが重要である。 The static electricity neutralizing paper applied to the present invention contains 3 to 15% by weight of carbon fiber short fibers, 20 to 70% by weight of the entire synthetic fiber short fiber ring, and the remainder is wood pulp. It can be obtained by paper-making a mixture containing a binder and a binder to a paper weight of 50 g/m 2 or less using a pure wet paper-making method, and uniformly dispersing short carbon fibers. That is, it can be obtained by floating carbon fibers, short synthetic fibers, and wood pulp in water, pouring them onto a mesh conveyor, dewatering them, and drying them with rollers. In this case, it is important not to apply heat or pressure, or even if it is done, to avoid heating or pressure that would inhibit the protrusion of the carbon fibers.

硬度が上り使いにくくなる。 Furthermore, in the present invention, the basis weight (basis weight) of the paper is set to 50 g/m 2 or less, which increases the chance for the tips of the carbon fibers to protrude from the surface (improves performance). , the later handling of this paper (taping, laminating, labeling, etc.) is improved. If the basis weight is greater than 50 g/m 2 , the protrusion of the carbon fibers from the surface will decrease, and the paper will become hard and difficult to use.

ことができる。(Effects of the Invention) As mentioned above, the static electricity neutralizing paper applied to the present invention is produced by limiting the blending amounts of short carbon fibers, short synthetic fibers, and wood pulp to specific ranges, and uniformly making the paper. Because many short carbon fibers protrude from the surface of the paper, it has electrostatic properties with a half-life of 5 seconds or less and a frictional charging voltage of 40V or less. , there is no need for grounding, and air discharge prevents malfunctions, reduced efficiency, reduced safety, fires, explosions, and discomfort caused by discharge light and sound caused by electrostatic disturbances in various industrial fields. It is something that can be done. Since the abrasion-resistant static electricity neutralizing paper of the present invention has a knitted fabric layered on one side of the excellent static electricity neutralizing paper, it will not absorb static electricity when it comes into contact with other objects or touches people's hands. Prevents washi paper from being damaged by wear and tear. For example, when laminating knitted fabrics, woven fabrics, etc. using hydrophobic fibers, it is possible to prevent damage due to abrasion caused by static electricity neutralizing paper weakening due to exposure to rain or contact with moisture-containing items. .

重構造繊維などを使つたものでは得られない。 The effect of the present invention is that the island component of the antistatic polymer in which carbon black is uniformly dispersed in the synthetic polymer in the metal-plated fiber such as copper sulfide and the sea component is streaked in the fiber axis direction. This cannot be achieved by using conductive fibers with a structure in which carbon is dispersed in the core, or fibers with a core-sheath double structure in which carbon is contained in the core.

た。Example 1 5% by weight of short carbon fibers (1d x 6mm) produced from acrylonitrile polymer fibers by a conventional method, 45% by weight of short fibers of polyethylene terephthalate fiber (1d x 6mm), 35% by weight of wood pulp, and binder They were mixed at a ratio of 15% by weight. This mixture was further shredded through a beater to obtain a homogeneous mixture, and then electrostatically neutralized paper with a basis weight of 25 g/m 2 was produced using a wet paper making method. In this case, after dewatering in the papermaking process, heating and pressure that would inhibit the protrusion of carbon fibers were not applied during roller drying.
