5.6 Influence of Micronaire and Yarn
Strength
Textile research indicates that micronaire influences the amount of fibers
per cross-section, thereby affecting yarn strength. Generally, lower
micronaire fibers are smaller in perimeter, and thus finer, allowing more
fibers per cross-section. Conversely, as micronaire increases, fibers
become coarser allowing fewer fibers per cross-section in yarn.
