Sontara® Protect General Purpose

  • The Sontara® Protect customized offering for general purpose is known for its comfort, breathability and softness to the skin. Our offering has been tested and qualified for new general purpose categories 1 and 2 as recommended by French authorities, meeting the requirements for Aerosol Filtration Efficiency (AFE%) 70+ and 90+. The air permeability of these materials offers exceptional air flow for maximum comfort and breathability - it is 15-20 times greater than the 96 l/m2.s at 100PA requirement.

Sontara® Protect Supporting Materials

  • Sontara® Protect Comfort Layer (CL) provides higher air flow and softness to the skin compared to alternative products. Sontara® ensures high purity through a proprietary production process that is free from binders, chemical additives and adhesives. Sontara® Protect CL meets the ISO-10933 Bio-compatibility standard for skin contact.
  • Sontara® Protect offers material for mask borders and ties for respirators (FFP2 or N95) and surgical masks. Their high dimensional stability and strength make them ideal for this application.

Sontara® products are made using proprietary technology for high demanding applications. High-speed water jets are used to hydraulically entangle various fibers to form a strong absorbent web. Unlike many nonwoven fabrics, Sontara® uses no binders, chemicals or adhesives. It has exceptional mechanical strength, excellent absorbency, and because the fibers are washed during fabric formation, it exhibits very low lint. These unique features make Sontara® ideal for the cleaning requirements of the quality-conscious user.
