The gamma-irradiated version of series 410, a 100% polyester wipe knitted from filaments, is one of the most efficient cleanroom wipes for more critical areas, both in microbiological controlled and in purely particle controlled zones. The cloth is cut by laser and thus the wipe edges are sealed. After cutting, the wipes are professionally decontaminated in a cleanroom laundry and packed under ISO 4 conditions (EN ISO 14644-1). Even if made of 100% polyester, the double-layer wipes, quilted together by ultrasonic welding, have a very high absorption capacity. However, the liquid stored in the wipe is also evenly released back to a surface when required, which is why the series 410 is particularly popular in the pharmaceutical sector (in combination with disinfectants). The robust polyester knitted fabric shows its strength on rougher surfaces or on sharp-edged objects and/or surfaces. Due to the cleanroom-compatible post-cleaning after manufacturing, the wipes have relatively low levels of ionic and metallic contamination.
Facts
Polyester
Knit, 100% PES filaments, double layer, laser-sealed edges, gamma-irradiated.
Properties
- 100% polyester
- two-ply interlock fabric made of filaments, ultrasonically welded and quilted
- gamma irradiated
- edges cut and sealed per laser
- very low particle and fibre emission
- decontaminated in a cleanroom laundry
- double bag packed in a cleanroom (air cleanliness class ISO 4)
Advantages
- specially absorbent due to the double knitted construction
- reduced particle and fibre emission due to the sealed edges
- wide range of applications, especially in the field of surface disinfection
Applications
- cleaning wipe especially for critical areas
- cleaning wipe for areas where high absorbency and purity are required
- good suitable for angular, rough surfaces and objects which might prematurely damage a non-woven fabric wipe
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.
