A cleanroom wiper comprising a woven fabric having a first fiber comprising a nylon/polyester conjugate and a second fiber comprising a polyester wherein the first and second fibers are woven using a repeating pattern having six warp threads comprising the second fiber and eighteen weft threads comprising the first fiber wherein the woven fabric is pre-saturated with only ultrapure water which immediately and evenly wets into the wiper.
A method for making a pre-saturated cleanroom wiper saturated with only ultra pure water comprising the steps of:
- weaving a first fiber comprising a nylon/polyester conjugate and a second fiber comprising a polyester in a repeating pattern having six warp threads comprising the second fiber and eighteen weft threads comprising the first fiber to create a woven fabric;
- processing the woven fabric with high temperature, high pressure, and at least one surfactant;
- cleaning the woven fabric with aseptic ultra pure water;
- drying the woven fabric;
- cutting the woven fabric and sealing the edges of the woven fabric to create individual wipers;
- and
