Modal silver fiber woven double-sided fabric is light and breathable, the surface is smooth and soft, without elasticity, one side is modal material, which can directly contact the human body, non-conductive, and the other side is silver fiber, which is very conductive and has great shielding performance. Because it has no elasticity, it can be used as home textile products, bed sheets, quilts, functional clothing linings, etc.

Modal Silver Fabric

Modal silver fabric is a textile material that combines modal, a type of natural fiber derived from beech trees, with silver threads or particles. It has good conductive/shielding properties as well as practical textile properties. This kind of fabric is often used to protect high-frequency electromagnetic radiation, has high shielding attenuation even at very high frequencies, and can also be grounded to shield low-frequency electric fields.
