SPECTROSCOPIC_DISCUSSION:
As expected, burlap's spectrum strongly resembles the dry vegetation used to fabricate it. It has the slightest hint of an 0.65 micron absorption perhaps due to residual chlorophyll. From 1-micron onward into the near infrared region, it has absorptions attributable to water, lignin, and cellulose. G. Swayze.
