REPAIR PROCEDURES
I
2-4. MATERIALS
Materials used in the repair of sleeping bags and accessories, will be serviceable materials recovered from
similar salvaged items, when authorized, or will be new material as specified in section Ill. New materials will be
requisitioned from stock under the stock numbers and/or item description and will conform to the appropriate
specifications. When not available from stock, materials may be purchased locally that conform as closely as
possible to the standard material.
2-5. REPAIR AND MAINTENANCE OF SLEEPING BAGS, INTERMEDIATE COLD AND
EXTREME COLD TYPE Il.
a. Inspection. Inspect the sleeping bag to determine the extent of damage, normal wear, and the need for
repair.
b. Cleaning. Clean off mud or other foreign matter with brush, damp or dry cloth, or scrub the exceedingly
dirty areas with limited amounts of water that will not saturate the insulation; then rinse off and dry.
c. Repair.
(1) Any filling material (feathers and down) which has been lost through holes or tears will be replaced
with filling material taken from sleeping bags classified as condition “H” or with material obtained
which conforms to Type II of MIL-F-43097 for the intermediate cold and extreme cold. Insert sufficient
filling material to obtain about the same bulk as in adjacent undamaged channels,
(2) Iron-on patches.
(a)
(b)
(c)
Cut patches to the desired size and shape such that the patch, when applied, will extend
approximately 3/4 inch (1.9 CM) in all directions from the tear or damaged area. Patches will have
rounded corners.
With the sleeping bag unzipped, place the area to be patched on a wooden or other nonmetallic
surface not effected by heating or ironing. Smooth out by hand. Remove any feathers on the area
to be patched. Pre-warm the area to be patched by pressing with a household electric dry or
steam iron. Use a dry iron set at “cotton” or high as possible without scorching the fabric for about
5 seconds,
Immediately cover with patching material previously cut in the desired size and shape. Hold the
iron on the patch for about 8 seconds. Use only a slight rotating or reciprocal motion of the iron.
Allow to cool about 5 seconds or long enough so that the patch will not drift off when the patched
bag is removed from the table. Adjust the heating, pressing, and cooling times as required for the
specific iron being used, Check the quantity of the adhesive bond periodically as follows and
adjust heating times and temperatures of the iron accordingly.
(d) Test a patch that has cooled for about 5 minutes by picking with the fingers at an edge of the patch
until a tab 1/4-to 1/2-inch (0.635 to 1.27 CM) long is formed. Pull hard on the tab with fingers. A well-
bonded tab will be difficult to peel off, This will indicate that iron adjustment and time heating the
patch is adequate. Replace the test patch with a new patch or re-iron the old patch.
