Micronaire and measurement methods
Micronaire and measurement methods
Micronaire is the transliteration of English Micronaire. The Micronaire value is a comprehensive indicator that reflects the fineness and maturity of cotton fiber. It is one of the important intrinsic quality indicators of cotton fiber and is closely related to the use value of cotton fiber. The micronaire value is divided into three levels: A, B, and C. Level B is the standard level. The value range of grade A is 3.7-4.2, which indicates good quality; the value range of grade B is 3.5-3.6 and 4.3-4.9; the value range of grade C is 3.4 and below and 5.0 and above, which indicates poor quality. The specific measurement method is to use an air flow meter to measure the air permeability of a constant weight of cotton fiber after being pressed into a fixed volume, and express it as a numerical value on this scale. The larger the value, the thicker the cotton fiber and the higher its maturity. jaKoImGk
