The Heat-resistant Treatment on Textured Woven Glass Fiber Fabric
The heat-resistant treatment on Textured Woven Glass Fiber Fabric typically involves several processes designed to enhance the fabric’s ability to withstand high temperatures without losing its strength, shape, or performance. Here are the common treatments and methods:
1. High-Temperature Heat Setting
The fabric is subjected to controlled heating cycles at elevated temperatures (often between 300°C to 600°C) to stabilize the glass fibers and remove any residual stresses.
This process stabilizes the fabric's dimensions and texture, enhancing dimensional stability under heat.
2. Surface Coating or Impregnation
Application of heat-resistant coatings such as silicone, ceramic-based coatings, or specialized binders that increase thermal stability and protect against oxidation and thermal degradation.
Coatings can also improve abrasion resistance and reduce fiber fuzziness.
3. Chemical Treatment
Use of heat-resistant sizing agents or chemical finishes applied during or after weaving to improve fiber-matrix adhesion and thermal endurance.
These treatments help the fabric maintain integrity when exposed to thermal cycling.
4. Texturing Process with Heat Stabilization
The texturing (creating surface patterns or crimps) often involves mechanical and thermal processes to impart a 3D structure that improves flexibility and mechanical performance at high temperatures.
Heat stabilization ensures the textured shape is retained during use.
5. Post-Treatment Annealing
Sometimes the fabric undergoes annealing, a slow cooling process after heat setting, to relieve internal stresses and enhance thermal resistance.
