Properties of Glass Fiber

Glass fibers for consumer purposes are mostly made from filament yarns. The glass fiber has certain properties as follows:

• Strength: Glass fiber is strongest to all fibers. Some types of glass fibers are stronger than equivalent diameters of stainless steel. The fiber has poor abrasion resistance, which can be overcome to a certain extent by Coronizing.
• 
  
  
• Elasticity: The fiber is virtually inelastic. It is not suitable for clothing, but apt for use in draperies and curtains as the fabrics will not stretch or sag out of shape.
• 
  
  
• Resilience: Glass fiber is quite resilient and has good wrinkle resistance properties.
• 
  
  
• Absorbency: The fiber is not absorbent. The fabric is water repellent an unaffected by it. The fiber if not suitable for cloth manufacturing.
• 
  
  
• Heat Conductivity: The fiber is a good conductor of heat. It is excellent insulation materials having a number of industrial applications.
