Claims17
A cleanroom wiper comprising a woven fabric having a first microfiber material comprising a nylon/polyester conjugate comprising 25-30% nylon and 70-75% polyester and a second microfiber material comprising a polyester wherein the first and second microfiber materials are woven using a repeating pattern having six warp threads and eighteen weft threads and the woven fabric is pre-saturated with only ultrapure water which immediately and evenly wets into the wiper.
The cleanroom wiper of claim I wherein the woven fabric comprises sealed edges.
A cleanroom wiper comprising a woven fabric having a first microfiber material and a second microfiber material where the first and second microfiber materials are woven using a repeating pattern having six warp threads and eighteen weft threads 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 microfiber material comprising a nylon/polyester conjugate comprising 25-30% nylon and 70-95% polyester and a second microfiber material comprising a polyester to create a woven fabric wherein the step of weaving comprises weaving the first and second microfiber materials using a repeating pattern having six warp threads and eighteen weft threads;
- 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
- packaging and pre-saturating the wipers with only ultra pure water.
