BACKGROUND ART Conventionally, a method of weaving conductive fibers into textile products has been known as a measure to prevent static electricity. This device utilizes a mechanism that collects static electricity charged on a textile product onto conductive fibers and releases it from the tip of the fiber by corona discharge to eliminate the static electricity on the textile product. However, even if such means are used, the corona discharge effect (current collection effect) of the textile product is small, and it cannot be used as a surface material for automobile seats. The electrostatic charge (thermal effect) is also extremely small, and it is hardly expected that static electricity will be released to the sheet and removed by contact with another object, such as a human body charged to a high potential.

For this reason, for the purpose of static elimination effect, a conductive backing agent layer containing 20% to 5096 carbon fine particles (surface resistance 1O8
0 or less) and grounding the backing agent layer has been proposed as a static eliminating sheet (Utility Model Application No. 60-4).
No. 01197) 5 <Problems to be Solved by the Invention> When a conventional vehicle is used as a surface material for a car seat, if the seat and the human body are in contact from the beginning, static electricity charged on the seat and the human body The electrostatic potential between the two always flows through the conductive fibers and backing material layer to the car body and is removed, so the electrostatic potential between the two does not rise. The human body caused by this is charged to a high potential, and when the seat and the human body come into contact again, it is observed that a significant spark discharge occurs. A similar phenomenon also occurs when a human body charged to a high potential due to other causes comes into contact with the same sheet. This phenomenon is similar to spark discharge when a highly charged human body comes into contact with a good conductor such as metal. Therefore, m
The sheet described in I is not always effective as a static electricity eliminating sheet for vehicles.

Composite fibers made of polymers mixed with these conductive powder particles and polymers that do not substantially contain conductive powder particles are examples.Although thin metal wires are also examples of conductive fibers, these fibers are generally These conductive fibers generally cannot be used in the present invention due to their electrical resistance, which will be described later, being less than 104 Ω/cm.

Even in the case of fibers made of polymers mixed with carbon or metal conductive powder particles as described above, or composite fibers containing such polymers, the electrical resistance value changes greatly depending on the amount of conductive TM and powder particles added. . Therefore, it is necessary that conductive powder particles be added so that the electrical resistance value falls within the above range.

In addition, in order to provide this sheet with sufficient antistatic performance and static elimination performance, the electrical resistance mentioned above must be 105 to 109 Ω/a.
It is necessary for the conductive fibers of m to have a certain density of -1-[to communicate the semiconductor layer on the back side with the substrate so that napped hairs are present on the surface. The napped fibers have the function of lowering the potential of the charged body to some extent by collapsing the charged body by collecting current in the straight line with which it comes into contact when a charged body charged at a high potential approaches. The napped density of the electrically conductive fibers that communicate with the necessary substrate as used in the antistatic sheet of the present invention is at least 1 per 10 ultrafine fibers/cm 2 . If it is less than that, sufficient current collection and discharge effects cannot be obtained. However, if the density of the conductive fibers, which are 10 times or more thicker than the microfibers, becomes too high, the same effect will become saturated and no significant improvement will be observed. This increases the appearance of a shimofuri style, which is undesirable.

The semiconductor layer needs to have a surface resistance of 104 to 1010 Ω; if it is 10”Ω or more, the static electricity is removed by contact with a charged body, and if it is less than IO1IΩ, the core layer becomes close to a conductor. Depending on the potential of the charged body, spark discharge may occur between the sheet and the sheet, which is undesirable.The backing agent is made by, for example, mixing carbon powder particles in a normal backing resin in an amount of 1.5 to 15% by weight based on the weight (solid content) of the resin. It can be easily obtained by dispersing it.Also, in the case of a film, it can also be easily obtained by adjusting the amount of conductive powder or substance mixed.

In the present invention, it is necessary that the conductive fibers and the semiconductor layer are in contact with each other. If they are not in contact with each other, the corona discharge ability of the static electricity collected in the fabric layer decreases, and at the same time, leakage to the semiconductor layer occurs. The effect will also be reduced. Further, it is preferable that the electrical resistance value of the conductive fiber is lower than the surface resistance value of the semiconductor layer from the viewpoint of the leakage effect to the semiconductor layer.

<Function> The composite sheet of the present invention is used by being grounded to a conductive layer. When a charged body such as a human body charged at a high potential comes into contact with the surface of this sheet, first, immediately before contact, the charged body is The static electricity is collected by the conductive fibers of the fiber layer, and the potential of the charged body is lowered by corona discharge.Also, the material of the present invention is not a conductor as a whole, and because it gradually releases static electricity and does not discharge all at once, it does not cause sparks. Instead, when the charged body and the sheet surface come into contact, the static electricity of the charged body flows to the semiconductor layer through the conductive fibers of the sheet more slowly than that of the conductor, and is eliminated by the earth. Therefore, when a charged body with a high potential comes into contact with the lard of the present invention, the charge of the charged body can be quickly removed without causing electrostatic disturbances such as electric shock or noise due to spark discharge.

The surface of this fiber sheet is buffed to form a napped layer of ultra-fine fibers, which is dyed in a high-temperature, high-pressure jet dyeing machine at 120°C, and then plunged to create an elegant appearance with a lighting effect. I got a suede style sheet. The average napped density of the ultrafine fibers was 104 pieces/am'', and the average napped density of the conductive fibers (B) communicating with the substrate was 25 pieces/cm2.

For comparison, a sample (■) of sheet (1) without semiconductor backing, and a conductor banking (30% carbon powder mixed in backing resin) with a surface resistance of 104 Ω instead of semiconductor backing of sheet (I) were used for comparison. Samples (III) were prepared, and their static elimination performance was evaluated. The results are shown in Table 1.

Table 1 Attenuation of electric potential due to contact with discharge lamp Automobile seats were prepared using these samples (1) to (III) as surface materials. Then, the manufactured seat was set in a car, and a person wearing a polyester shirt and a polyester jacket was seated in the seat under a temperature and humidity condition of 5°C - 12% RH, and the seat was moved back and forth for 10 seconds. I made it back and forth 10 times to create friction between the seat and my clothes.

Example 2 In the manufacturing method of sample (1) of Example 1, a pre-foamed resin liquid (carbon powder was added to lO weight λ%) as a semiconductor layer.
A sheet was manufactured in the same manner as Sample (I) except that a sheet containing a compound (including 100% polyester) was applied to the back surface and dried. At this time, the bubble content of the semiconductor layer was 65% by volume. Yes
The coating amount of the two-hand core layer was 95 g/m''. When a seat was fabricated using this sheet as a surface material, it showed extremely good control and static elimination ability, similar to sample (I). Furthermore, the seat itself was extremely flexible, and the seat surface material was extremely comfortable to sit on.
