Hazardous accidents may occur in any production site. Electro static charge build-up is one of such causes of hazardous accidents in many industries. For example: explosion ignited by discharge, deteriorated productivity, inferior quality by malfunctioning of system, contamination and etc. |
Kuraray developed Clacarbo, an electro-conductive fiber containing carbon, just when static electricity had been acknowledged hazardous problems to various industries. It is basically polyester filament having a special structure containing electro-conductive carbon. This anti-static material with suitable structure and function conforms to the static electricity safety guide of the Ministry of Labor: RIIS-TR-78-1.
Application field： petroleum refining , oil tankers, gas stations, thermal power plant, manufacturing sites of solvent, painting, coal mining industry, semi-conductor, etc.
How static elimination can be made
 Static charge generated on a garment can be eliminated by corona discharge through Clacarbo. This function is hardly influenced by the material of underwear worn. |
 |
 Because static charge elimination proceeds by corona discharge, the anti-static function can be maintained unaffected even under low humidity environment in which more static charge accumulation is generated. |
 |
Clacarbo has excellent durability standing with repeated washings as well as chemical resistance and resistance to the sunlight.

For the safe working environment
Filament Black Type
| Surface conductive type | Core conductive type | quadrangular exposed type | ||||
| Suitable for gaining
specifically low resistivity. KC-792 has resistivity range of 105-6. |
Carbon impregnated in core
part of fiber. No fall of carbon and presents high tenacity. |
quadrangular exposed type will offer the well balanced property of low resistivity and high tenacity. | ||||

The high end class material with low resistivity as well as thermal durability．
- Highest performance material hiring Genesta, high thermal resistivity Nylon developed by Kuraray．
- Lowest resitivityh(105-106)
- Durability against bending (Low Young, modulus)
- High resistance against elongation and abrasion
- Superb washability
- Stable with no shrinkage in hot water bath washing
- High thermal resistivity
High performance gained by Genesta
Genesta has property of lower crystal elasticity and lower glass transform point than polyester or nylon.
Which offers a material yarn to make the higher thermal durability and soft texture in finished fabric. Moist ratio with 1.76 which offers easiness of dyeing and finishing and stable in the use.
| Materials | Genesta | Polyester | Polyamide６ |
| Young modulus (cN/tex) | 55.6 | 90～160 | 20～45 |
| Melting point °C | 265 | 265 | 220 |
| Glass Transform Point°C | 120 | 70 | 50 |
| Crystal Elasticity (Gpa) | 31 | 125 | 142 |
| Typical Hydro-Ratio 65%RH | 1.76 | 0.4 | 4.5 |
Filament White type
| KC-220 | KC-971U | ||
 |
Tri-layered type using carbon presents white color. |  |
Supplied as POY used for carpet application. |
3 types of Staple
| Polyester Black (KC-585S) |  |
| Nylon Black (KC-575S) |  |
| Nylon White (KC-375S) Conductive layer with metal oxide |
 |
 |
- Outstanding low resistivity (105-106Ω/cm).
- Not exposing carbon on surface, no fall of of carbon layer.
- Outstanding thermo durability.
- Outstanding Chemical resistance.
- Low Young modulus with durability against bending.
