Samples are correlated to the product we sell by the inclusion of the product number in pale green (e.g. 80-120 200 muslin).
Oddy Test Results for the eight fabric samples (2 weights of cotton Muslin & 4 weights of cotton Flannel, samples tested in washed and unwashed state) as follows:
TEST 1: Oddy
An Oddy style test was conducted on eight fabric samples that represent four different materials. The test procedure was as follows: Each sample was enclosed in a glass vial with blanks of polished lead, silver and copper. Half of each sample was placed beneath the blanks so that the affect of direct contact as well as volatile contaminates could be assessed. Moist cotton was placed in each vial, which was then sealed and exposed to 60°C for 30 days. A control vial was prepared as above, but without a fabric sample, and exposed to the same conditions.

INTERPRETATION OF RESULTS
None of the fabrics caused any change in the test blanks. Based on this
test, the four fabrics appear to be appropriate for use in exhibitions. As a
precaution, it is recommended that the fabric be washed in hot water prior to
use.
