Abstract
A 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. The wiper may be pre-saturated and the saturation of the wiper may be done with ultrapure water that immediately and evenly wets into the wiper.
Claims19
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 that includes a number of weft threads that is three times a number of warp threads.
A method for making a pre-saturated cleanroom wiper 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;
- 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.
A pre-saturated 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 nylon/polyester conjugate of the first microfiber material includes 25-30% nylon and 70-75% polyester and 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.
