7. Remove clothes from the dryer.
Never allow laundered items to remain in the
dryer after completion of the drying cycle.
Laundry personnel should store freshly dried
clothing loosely and remain in the laundry after
the last dryer load to make sure there is no residual
buildup of heat in the clothing.
To avoid loss of items and production,
perform all drying operations by lot. Keep each
lot in its proper sequence and maintain an
identification marker with each lot during the
tumbling operation. Exercise the greatest care to
prevent any mixing of lots. Items requiring
approximately the same drying time should be
processed together, when possible.
Do not overload tumbler dryers as tumblers
are more sensitive to overloading than any other
type of equipment used in the Navy laundry.
Overloading retards drying time, produces
wrinkled work, and accelerates wear on the
equipment. No set time can be prescribed for
drying a load in a tumbler because drying time
is dependent upon steam conditions, weight of the
load, texture and type of material, and the amount
of moisture left in the work after extraction.
However, the maximum drying time for an
average load of cotton items in a 50-pound
tumbler dryer is approximately 20 to 25 minutes.
Under ideal conditions, the drying time required
for the same load may even be less. Very heavy
cottons require a slightly longer drying time.
Drying times used should be checked frequently,
and, if longer periods are required, the dryer may
have to be checked by maintenance personnel to
make sure there are no problems. Tumble drying
of washed synthetic or synthetic blend clothes and
linens properly carried out can minimize and/or
eliminate the need for pressing of the items. When
drying linen or this type of clothing do the
1. In all instances the tumbler dryer must not
be overloaded in order to allow adequate tumbling
action for wrinkle removal. Three-quarters of the
rated dryer capacity is recommended.
2. Hot tumble drying temperatures should not
be used. Exhaust-air temperature should be set
at a medium setting (between 140° to 160°F).
Drying time varies with the nature and size of the
load, but items containing a synthetic or high
percentages of synthetics in blends dry much faster
than similar 100 percent cotton items. Items
should not remain in the tumbler when it is not
3. Permanent press, synthetic, and synthetic
blend wearing apparel and linens, when removed
from the dryer immediately after cool down and
either placed on a hanger or folded, should be
suitable for use without ironing. Processing of
linens in this manner can help cut down the
workload for flatwork ironers.
Heavy items scheduled for pressing must be
preconditioned (partially dried) in tumblers for
