Interpretive Summary: There is currently a push to develop a standardized testing system on a global scale. This is leading toward the requirement that there be a way to correct fiber properties measured under non-standard atmospheric testing conditions. The research reported further tested the feasibility of correcting cotton fiber properties for changes in environment. In particular, we sought to determine the effect of changes in environmental conditions on HVI measurements of not only strength but also length and micronaire over a wide range of environments with a diverse set of test cottons. Our results essentially validated previous findings that there are consistent changes of strength and moisture content of cotton with changing environments leading to the possibility of a correction model. In addition, we present preliminary results that when the HVI is calibrated at the non-standard environments prior to measuring fiber strength and length, these values tend to be independent of changing moisture content.
