Epitropic Fibre |
Epitropic
fibre consists of carbon particles embedded in the surface
of polyester fibre. When blended with regular fibres, it
confers static conductivity to textile fabrics – usually,
although not exclusively, manufactured using nonwoven technology.
Epitropic fibre is supplied packed into
cartons, each containing 20kg.

| ELECTRICAL
PROPERTIES |
| |
Electrical
resistance of Epitropic fibre is 10 – 100 Megohms/cm |
| |
Approximately
1% Epitropic fibre prevents discomfort from static in everyday
clothing and carpets |
| |
2% –
5% Epitropic fibre is necessary in fabrics for industrial
filters and safety workwear |
| |
Resistivity
is approximately 1 – 100 Megohms/sq but is dependent
on the fabric and its construction |
| RESISTANCE
OF EPITROPIC FIBRE TO CHEMICAL AGENTS |
| Acids |
Except under
the most extreme conditions the rate of acid hydrolysis
is very slow, therefore good resistance to the majority
of mineral and organic acids can be expected. |
| Alkalis |
Aqueous alkalis except ammonia and its derivatives
cause progressive solution of the fibre. Ammonia, quaternary
bases, amines etc. degrade the fibre without dissolving
it. Maximum level recommended is pH 10. |
| Oxidising
Agents |
Epitropic
fibre has excellent resistance to oxidising agents and withstands
bleaching processes. |
| Reducing

Epitropic
fibre has excellent resistance to reducing agents |
