Principles of Static Electricity Generation:

Chemical fiber material is a poor conductor of electricity, has a high specific resistance, due to contact friction and drying and other factors occurring charge aggregation of electrostatic phenomena.

 

Principle of antistatic

Antistatic treatment of fiber surfaces to reduce charge generation, accelerate charge leakage, or neutralize generated static charges.

 

Factors affecting the generation of static electricity

  1. Fiber hygroscopicity: the better the hydrophilicity of the fiber, the more moisture absorption, the better the conductivity, the better the anti-static effect.

Natural fibers have high hygroscopicity, low resistance and less static electricity; synthetic fibers have low hygroscopicity, high resistance and more static electricity.

  1. Air humidity: The lower the relative humidity of the air, the lower the moisture absorption rate of the fiber, the easier it is to get static electricity.
  2. Temperature: as the temperature increases, the resistance decreases, the amount of charge decreases, and static electricity decreases.
  3. Friction coefficient: the rougher the fiber surface, the higher the friction coefficient, the more contact points, the faster the contact speed, the easier the static electricity.

 

Antistatic process

  1. Raw yarn antistatic:

In the spinning process mixed with conductive staple fibers (metal, metal-plated, organic conductive fibers) to reduce the resistivity of the yarn and accelerate the leakage of charge.

Organic conductive fibers: nylon-based, polyester-based, acrylic-based

 

  1. Use of antistatic agent additives:

Hydrophilizing fabrics with surfactants to improve moisture absorption, reduce the coefficient of friction, and inhibit the generation of reduced static charges to eliminate static electricity.

 

*Types of antistatic agents

 

  1. Anionic type
  2. Cationic type (strongest adsorption, improves the feel of fabrics)
  3. Amphoteric (expensive, small range of use)
  4. Non-ionic (weak anti-static effect in general humidity, the greater the humidity, the better the effect)
  5. Coating

 

Conductive materials (graphite, copper powder, silver powder) are mixed into the coating to coat the surface of the fabric to reduce yarn resistivity and accelerate charge leakage.
