This report compares the performance of blended Micronaire mixes of cotton with that of natural mixes of the same average reading to determine the economic feasibility of using cottons "discounted" in price for high- or low-Micronaire readings. Cottons ranging from 3.2 to 5.2 in Micronaire were selected from the 1968-69 crop and spun into 40s carded yarn. Twenty- three mixes were spun--five natural Micronaire mixes and 18 blended. In addition to the test results, the report demonstrates a method of potential usefulness to commercial mills for determining appropriate price discounts for cottons of high- or low-Micronaire readings.
