The gamma irradiated version of the 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.
Facts
Polyester-cellulose
Non-woven, 45% PES / 55% CEL, hydroentangled, twill-like, gamma irradiated
Properties
- 45% polyester / 55% cellulose
- hydro-entangled non-woven fabric
- gamma-irradiated
- low particle and fibre emission
- relatively abrasion resistant
- special twill-textured surface
- good absorptive capacity
- double bag packing
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
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.
