The term “with nap”is used on sewing
patterns and instructions; it affects the
amount of yardage you need, how the
pattern is cut, how the item is sewn and
pressed, and even how the final garment is
laundered. This guideline will help you
understand napped fabrics. For sewing tips
and garment care information, see
Guideline 4.218.
A fabric with “nap” has gone through a
finishing process that raises the fiber ends
to the surface where they are clipped,
brushed or left upright. This creates surface
texture that in turn creates a soft hand, a
heavier fabric and, usually, a warmer fabric.
