Single-use Tyvek® IsoClean® vs. Polyester reusable textile - penetration by hydrostatic head


DuPont scientists tested the barrier performance of a commercial polyester, reusable textile garment, typically used in European cleanrooms and Clean & Sterile Tyvek® IsoClean® garment model IC 183 B DS. The tests were performed on new garments and results do not include garment wear and multiplewashing and irradiation cycles.

The tests measured penetration by hydrostatic head and included the following:

1. Test method according to en 20811 - Determination of resistance of textile fabrics to water penetration – method of hydrostatic pressure


2. Manual permeability test - Pfaff tester controlling the permeability with a testing pressure set manually


One can see that both tests show clearly demonstrate barrier performance of both fabrics:

  • Hydrohead Test (EN 20811) shows that Tyvek® IsoClean® Clean & Sterile is significantly more resistant to water than the reusable polyester fabric.
  • Manual permeability test also proves that Tyvek® IsoClean® Clean & Sterile is by far more resistant to water than the reusable polyester fabric.
