ABSTRACT:
A swab having an absorbent end comprising a material strip of tubular knit fabric wrapped with a first blind end, helically to a tip and reverse helically to a termination point distal from the tip provides low contamination for use in clean room processes. Lost fibers or lint are precluded by the trapped fiber edges of the material strip forming the absorbent tip of the swab while burying of the first end of the material strip in the blind wrap and combined sealing, severing, and adhering of the second end of the material strip to complete the swab distal from the tip, further precludes fiber contamination.
