TECHNICAL TEXTILES > ESD FABRICS
Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.
The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative).
As computers and electronics become ever more pervasive in consumer products so an increasing number of manufacturers will need to apply anti-static control measures.
One such measure is antistatic apparel because people are the greatest source of static charge in the workplace.
The material our clothes are made from and the soles of our shoes can influence static electricity too.
Weather affects it as well. There is more build-up of static charge when the air is dry.
Most people feel harmless shocks at around 2,000-5,000 volts. The people are the greatest source of static charge in the workplace.
Static electricity is generally harmless to the individual but if not controlled, electrostatic discharge can cause product damage to electrostatic sensitive devices and lead to machinery downtime, lost man-hours, returned products and warranty costs particularly in the semiconductor and electronics industries, which lead 5 billion USD of damage to products each year.
Our all antistatic fabrics can possess surface resistance between ( 106-109 ohm)
All anti-static fabrics have EN1149 certificate.

ESD Fabrics' Main Colors :
Most discharges are harmless to people and goods. However, electrostatic discharge can also cause fire, explosion or disruption and / or damage to electronic equipment.
ESD Lab Coat and ESD Fabrics, manufactured with conductive fibers, are recommended.
ESD Lab Coat and ESD Fabrics are to prevent the destruction of the sensitive components and the build-up of discharge sparks.
