ABSTRACT:
A conventional tunnel-type continuous batch washer is modified for use as a commercial bleaching machine by (1) lowering the rotational oscillation angle and speed of the machine's inner drum structure relative to its normal washing settings; (2) altering the water counterflow positioning and characteristics; (3) maintaining the water in the various inner drum section modules at essentially identical, relatively high levels; and (4) modifying the bath temperature characteristics of the machine. When utilized as a commercial bleaching machine the modified tunnel washer has a bleach zone disposed at its inlet end and into which a hydrogen peroxide bleaching solution is injected, a finish zone disposed at its outlet end and into which a softening agent is injected, and a water-only rinse zone positioned between the bleach and finish zones. Each of these three zones is defined by one or more inner drum structure modules which may be tandem or single batch modules. The bleaching machine is representatively used to bleach originally manufactured white textile fabric items, such as athletic socks and undergarments, prior to their packaging for sale.
