Abstract
A pre-saturated wiper for use in a cleanroom environment, or other similarly controlled environment, that includes a woven fabric comprised of two separate and distinct microfiber materials which incorporates a unique weave pattern with sealed edges that is saturated with only Ultrapure water (UPW).
Claims20
A cleanroom wiper comprising a woven fabric having a first microfiber material comprising a nylon/polyester conjugate woven with a second separate and distinct microfiber material comprising a polyester wherein the first and second microfiber materials are woven using a repeating pattern having an even number of warp threads and an even number of weft threads where the number of weft threads in the repeating pattern is three times the number of warp threads and 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 with a second separate and distinct microfiber material comprising a polyester to create a woven fabric having a repeating pattern with an even number of warp threads and an even number of weft threads where the number of weft threads is three times the number of warp 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.
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 separate and distinct microfiber material comprising a polyester to create a woven fabric having a repeating pattern with an even number of warp threads and an even number of weft threads where the number of weft threads is three times the number of warp 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.
