13-7 REPAIR AND MAINTENANCE-Continued
The area to be patched and the patching material must be clean and dry.
Each patch shall be placed in the desired final position and a ball point pen tracing made of Its entire
border. The patch shall be removed and a coat of tent patching cement applied within the traced
area. Allow cement to dry approximately 10 minutes.
Carefully press the patch in place. The poncho may be handled and folded immediately.
Stitching and restitching. Machine sew all items being repaired except in emergency repair. Backstitch all
stitching at ends to prevent raveling. Properly maintain thread tension to prevent loose stitching. Use
same stitching space, and type of seams as that of original construction. Restitch all seams having loose
and/or weak thread. Overstitch thread breaks in double lock stitching (type 401) not less than 1/2 inch
(1.30 cm) at each break. For information on the various stitch types used, see Federal Standard 751.
Thread sizes are found in Section III.
Drawcords. Replace missing, frayed, or otherwise defective drawcords cut from braid. Dip the ends of the
drawcords in a suitable synthetic resin or tip with nonflammable plastic to prevent fraying.
Cord for hood
46 inches (116.8 cm)
Hardware. Straighten bent and damaged hardware that is otherwise serviceable. Replace hardware such
as keepers, eyelets, and snaps that are missing or damaged beyond repair. Retouch or refinish hardware
as required. Thoroughly clean hardware of rust, corrosion, dirt or other foreign matter. Exercise care in
replacing or inserting eyelets and fasteners so as not to damage material. Tightly clinch the eyelets
without splitting. Tightly clinch fasteners.
Sealing of Seams. Apply seam sealant by brush on the stitching and needle holes and under the turned
edges of all restitched seams. Allow each coat to become dry to touch before applying the subsequent
coat. All restitching, except the peripheral hems and the facing piece seams around the face opening of
the hood, shall be sealed on the Inside of the poncho with a minimum of three coats. Seal outside areas
with a minimum of one coat of sealant, except that the earphone cover joining seam and hem shall not be
sealed on the outside. Restitched hems and facing piece seams around the face openings of the hood
shall not be sealed. The coats of sealant shall be allowed to dry before the ponchos are folded or before
sealed surfaces are allowed to contact other parts of the garment. Adequacy of the drying time may be
determined by unfolding a poncho which has been folded and stored for one hour. When the coats of
sealant are dry, the sealed seams shall be dusted thoroughly with talc. Use sealant prescribed for ponchos
in Section III.
