Series 303

Polyester-cellulose wipe

Back to our polyester-cellulose wipes

Series 303, a polyester-cellulose non-woven wipe, is versatile, both in microbiological controlled areas and in purely particle controlled areas. The special surface in the form of a twill structure (similar to ribs) also serves to absorb slightly coarser impurities, which can become trapped between the ribs. Although made of a non-woven fabric, the wipe has a certain abrasion and tear resistance (even when damp).
The cloth material combines the different strengths of cellulose (➜ absorbency) and polyester fibre (➜ abrasion resistance) and is therefore also a „happy medium“ in terms of cost. 

Series 303 is also available in a gamma-irradiated version.

Properties

  • 45% polyester / 55% cellulose
  • hydro-entangled non-woven fabric
  • low particle and fibre emission
  • relatively abrasion resistant
  • special twill-textured surface
  • good absorptive capacity
  • double bag packing
  • gamma irradiated available

Advantages

  • good chemical compatibility with different solvents and cleaning agents  
  • multipurpose
  • can also absorb slightly coarser impurities due to the special surface, without damaging the surface to be cleaned.
  • cost-effective

Applications

  • all-purpose wipe
  • absorbency of liquids and spills
  • suitable for cleaning tools
  • workplace cleaning – especially for smooth surfaces

Product recommen­dation based on cleanroom classes


123456789low dust


ABCDE

Of course, cleanroom wipes used in ISO 5 can also be used in ISO 9, but in this case the economic efficiency and usefulness should be considered.

A 1 to 1 allocation of cleanroom wipes to an air cleanliness class according to ISO 14644-1 is not possible. Recommendations can only be made on the basis of special properties relevant from a cleanroom technical point of view, such as "abrasion resistance" or "particle emission". Users can find further information on this in VDI Guideline 2083 Part 9.2.
