Crepe
Bandage consists of characteristic fabric of plain weave. The warp
threads are of wool, with a count not finer than 30 tex and not
coarser than 35 tex and of twofold cotton threads with a count,
after crepe twisting, not finer than 59 tex, each containing not
less than 21 folding turns per cm. The weft threads are of singles
cotton thread with a count not finer than 30 tex.
The
warp threads are arranged one twofold thread S-twist, two wool threads,
one twofold thread Z-twist, two wool threads, repeated, together
with twofold cotton binding threads at each cut edge.
The fabric is clean and reasonably free from weaving defects and
contains not more than traces of leaf residue, seed coat and other
impurities.
Crepe Bandage may be dyed. It is in one continuous length with no
joins and has fast edges.
For the purpose of this monograph the width is that portion between
and including the fast edges of the unstretched bandage.
