es Nylon, no poly, como dice Mercurio
The Navy Clothing and Textile Research Facility (NCTRF) has developed and
evaluated two experimental 85/15 wool/nylon, 22-ounce per linear yard, melton
materials for possible replacement of the current Cloth, Melton, Wool,
MIL-C-16290. One of the experimental materials was constructed identically
to the standard material, while the other was constructed with a 10% reduction
in warp and filling yarns. Those materials were subjected to laboratory tests
of 18 material characteristics, including weight, shrinkage, break strength,

acidity, colorfastness, abrasion resistance, and permeability. Test results
indicated that both constructions are suitable as a replacement for the
standard. As a result, the modified construction with the 10% reduction in
warp and filling yarns is being recommended for adoption as a replacement for
the standard 100% wool melton. (U)
