Application:
- glass voluminized roving is used for manufacture of filled composites and friction articles, woven and nonwoven materials.
- voluminized glass fibers are widely used in such fields as air filtration, thermal insulation, manufacture of filtering fabrics.
- voluminized rovings substitute for asbestos in many fields.
Advantages:
- voluminization improves performance and adhesive characteristics, hygienic properties of synthetic fabrics.
- texturized and voluminized glass yarns can save greater amount of air than single yarns thus providing better insulating properties.
- fabrics of voluminized fibers are notable for high strength, low density and good insulating properties, thermal stability, low thermal conductivity, high speed of filtration, low shrinkage, problematic deformation.
