ChemStat 969Z Plus
Antimicrobial Fabric

ChemStat 969Z Plus is the ultimate garment fabric for sterile cleanroom environments, such as pharmaceutical and biotechnology manufacturing. It offers the opportunity to lower the bioburden in a cleanroom via the garment system.

Composed of 100% multifilament polyester, ChemStat 969Z Plus relies on a conductive stripe to render the fabric static-dissipative. Although ChemStat 969Z Plus is a plain weave (taffeta) construction, its design avoids the stiffness and scratchiness of other high-density taffetas offered elsewhere.

Significantly, ChemStat 969Z Plus employs polyester fibers that are inherently antimicrobial to provide a barrier to bacteria and fungi. These state-of-the-art fibers contain in their polymer structure silver and zinc ions permanently affixed in a ceramic matrix. The ions interfere with cell division, in a manner similar to iontophoresis.

ChemStat 969Z Plus is effective against a broad range of bacteria and fungi, and, unlike antibiotics, does not evoke resistant strains of bacteria. Typically affected bacteria and fungi are:

  • Aspergillus niger
  • Bacillus subtilis
  • Escherichia coli (E. coli)
  • Klebsiella pneumoniae
  • Methicillin-resistant staphylococcus aureus (MRSA)
  • Penicillium citrinum
  • Pseudomonas aeruginosa
  • Salmonella typhimurium
  • Staphylococcus aureus
  • Tricophyton mentagrophytes
  • Vibrio parahaemolyticus
The anti-microbial effect is not altered by acids, organic solvents, or disinfectants. ChemStat 969Z Plus may be universally laundered and sterilized. ChemStat 969Z Plus optionally offers splash resistance using a Teflon® Plus fluorochemical surface finish.

ChemStat 969Z Plus is available in Linen White and Light Blue.

Teflon is a DuPont registered trademark for its fabric protector.
