INTERMEDIATE COLD AND EXTREME COLD TYPE II SLEEPING BAG REPAIR

0008-3

Filling Material Repair

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.

Iron-on Patches

1. 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.

2. With the sleeping bag unzipped, place the area to be patched on a wooden or other nonmetallic

surface not affected by heating or ironing.

3. Smooth out by hand. Remove any feathers on the area to be patched.

4. 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.

5. Immediately cover with patching material previously cut in the desired size and shape.

6. Hold the iron on the patch for about 8 seconds. Use only a slight rotating or reciprocal motion of the

iron.

7. 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.

8. Check the quantity of the adhesive bond periodically as follows and adjust heating times and

temperatures of the iron accordingly.

NOTE

A bonded patch which has a lifted edge or which is suspected or found by the check
test to be weakly bonded may be re-ironed, e.g., replacement is not required.

A small amount of patch adhesive strike-through is not objectionable for sleeping bag
repair, provided the patch meets the check test.

9. 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.

10. Replace the test patch with a new patch or re-iron the old patch.

END OF TASK

Repair of Binding Tape

1. Overlap the binding tape with new tape of same size and type, extending the new tape at least 1 inch

beyond the damaged area.

2. Turn the binding edges under ½ inch (1.27 cm).

3. Using a medium-duty sewing machine, size E thread, 7-11 stitches per inch, sew 1/8 inch (0.31 75

cm) from edge of tape.

4. If the damaged area is at the face opening eyelets, remove the eyelets prior to performing the above

repair. Remove and replace the eyelets as specified section Eyelet Repair.

Eyelet Repair

Eyelets may be reset using appropriate dies when damage is minor. Any eyelet that cannot be fixed by
resetting must be replaced as outlined below.

1. Remove a damaged eyelet by cutting it with diagonal wire cutters. Be careful not to cut or damage the

fabric, webbing or tape.

2. Without damage to the fabric, install the new eyelet (with proper sized dies) according to the original

construction.

END OF TASK

Re-stitching

Re-stitch using sewing machine, thread and stitch listed in Table 1. Re-stitch directly over the original
stitch pattern as closely as possible. Lock each row of stitching by backstitching at least ¾ inch (1 .905
cm). Maintain thread tension to prevent loose stitching.

Drawstring Casing and Drawstring Repair

Holes or tears less than ½ inch (1.27 cm) may be darned. Foot tie straps with holes or tears greater than
½ inch (1.27 cm) in length or diameter shall be replaced as follows.

1. Cut the drawstring at the edge of binding tape where it is attached to the face opening.

2. Cut a length of nylon braid 30 ± 1/2 inches (76.2 ± 1.27 cm) long and fuse cut ends.

3. Knot one end of drawstring with a figure eight knot located 3/8 to 5/8 inch (0.953 to 1.588 cm) from

end.

4. At one end of casing pass unknotted end of drawstring through opening formed by a bartack and

position drawstring within the casing with the unknotted end protruding approximately two inches from
other end of casing and on opposite side of bartack, i.e., not within the opening formed by the
bartack.

5. Fold the end of drawstring that is unknotted under 1/2 inch and position folded end even with edge of

binding tape and against end of drawstring casing.

6. Bartack or stitch through folded end of drawstring within a 1/2 inch (1.27 cm) bartack or with 3 rows of

stitching.

7. Install other drawstring in the same manner except start from other end of casing.

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.

CAUTION

Do not starch, bleach, or dry clean. Discoloration and degradation of infrared protection
capacity of the material will result.

Field Laundry

The ECWSS sleeping bag, hood and socks will be laundered using formula II of FM 10-280. Bivy Cover
will be laundered using formula Vlll of FM 10-280.

CAUTION

Do not starch, bleach, or dry clean. Discoloration and degradation of infrared protection
capacity of the material will result.

Machine/Hand Laundering

Sleeping Bags, Hood and Socks may be machine laundered using the delicate/ gentle fabric cycle or by
hand, using cold water (Up to 85° F/30°C) and cold water laundry detergent. Rinse in clean cold water.
The Bivy Cover may be washed using the wash & wear/permanent press fabric cycle or by hand, using
warm water (Up to 90°F/32°C) and formula Vlll of FM 10-280. Rinse thoroughly in clean warm water.

CAUTION

Drying temperature for sleeping bag must not exceed 130°F (54°C). Degradation of the
component materials will result.

Do not press. Degradation of the component materials will result.

Drying

Tumble dry the Hood and Socks at lowest fabric cycle delicate/gentle. Do not exceed 90°F (32°C) at no
more than 2/3 capacity. Remove immediately at end of drying. Avoid over drying. To drip dry, remove
from water and place on rustproof hanger. Tumble dry the Bivy Cover at low temperature (100° F/38°C)
and remove immediately from dryer. Avoid over drying. To drip dry, remove from water and place on
rustproof hanger.
