ABSTRACT:
A wiper for use in cleanrooms and other controlled environments is made using a knit fabric tube rather than a fabric sheet. The fabric tube is knit with a diameter approximately equal to the preferred wiper dimension and is presented directly to an apparatus for sealing and cutting. A sequence of spaced strips are fused into the fabric tube perpendicular to its length. Individual two ply wipers are separated from one another along a cut line midway in the strips. The wipers are characterized by lower costs due to fewer fabrication steps and a 50% reduction in the number of wiper edges requiring treatment.
