Bale management involves choosing bales of cotton or polyester according to fiber characteristics to achieve consistent processing conditions and yarn quality. Factors like average and range of micronaire, color, and maturity should be similar for all mixes in a lot. It is best to use mixes with very low micronaire ranges from 0.6 to 1.0. Bale management also includes conditioning cotton mixes for 24 hours at 25°C and 45-60% relative humidity to prevent fiber damage from high or low moisture levels.
