When talking about cleanroom wipers, the edge is the primary contaminant source. If your environment requires critically low levels of particle and fiber release, then this blog is for you!  Cleanroom wipers come in a variety of substrates, and each has different levels of contamination based on the edges. For example, a Polyester wiper with a knife cut edge will release fibers during the application. The “knife-cut edge” method consists of using a steel blade to cut the fabric… this method can leave a certain amount of threads in the wiper open and loose and can lead to particulate contamination in your cleanroom.  On the other hand, let’s say we take the same Polyester wiper but instead of cutting the edges with a steel blade, we cut with the “Pressure-Heat seal” method. The wiper edge is cut and finished by using heat and pressure to form the border of the wiper; the edge is ultrasonically sealed. This process virtually erases any risk of contamination by thoroughly sealing the edges.  In conclusion, there are a variety of wiper edge treatments to choose from, and you should always keep that in mind when choosing the right wipers for your cleanroom.
