<p>This application relates to a spunlaced fabric and a process for the production of a spunlaced fabric wherein the fabric is intended for use as a cleanroom wipe. Such cleanroom wipes preferably produce a low number of particles while having high absorbency. The fabric of the present invention essentially consists of a mixture of 25 to 65 wt. % cotton or rayon cellulose fiber and 35 to 75 wt. % polyester fiber. The fabric is further characterized in that it has a particle count of no greater than 18 million particles/m2 as measured by the Biaxial Shake (IES-RP-CC-004.2), an Intrinsic Absorbance of at least 5, and a Particle Sorbency Quotient of less than 55. The process of producing the fabric under the present invention is characterized by passing a web of 25 to 65 wt. % cotton or rayon cellulose fibers and 35 to 75 wt. % polyester fibers through a first series of water jets operating at a total impact energy of at least 10 X 10-3 horsepower-hour-pounds force/pound mass and a second series of water jets at the opposite side operating at a total impact energy of at least 20 X 10-3 horsepower-hour-pounds force/pound mass. In the process, the total impact energy of both sets of jets is at least 40 X 10-3 horsepower-hour-pounds force/pound mass.</p> |
