Series 309

Polyester-cellulose wipe

Back to our polyester-cellulose wipes

Series 309, a lightweight polyester-cellulose non-woven wipe, is versatile in use, both in microbiological controlled zones and in purely particle controlled areas. Although it is made of a non-woven fabric, the wipe has a certain abrasion and tear resistance (even when damp).
The material of the wipes combines the different strengths of cellulose (➜ absorbency) and polyester fibre (➜ abrasion resistance) and is therefore also a happy medium in terms of costs. In direct comparison to the series 300, 301 and 302, the series 309 is less clean and its mass per unit area is significantly lower. This explains the price advantage.

Properties

  • 45% polyester / 55% cellulose
  • hydro-entangled non-woven fabric
  • relatively abrasion resistant
  • good absorption capacity
  • packed in a double bag

Advantages

  • good chemical compatibility with different solvents and cleaning agents  
  • versatile in use
  • lighter than Series 301, therefore very 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.
