FIBRE FINENESS, YARN COUNTS AND CONVERSIONS: Micronaire value(cotton) : The unit is micrograms per inch. The average weight of one inch length of fibre, expressed in micrograms(0.000001 gram). Denier(man-made fibres): Weight in grams per 9000 meters of fibre. Micron:(wool): Fineness is expressed as fibre diameter in microns(0.001mm) Conversions: · Denier = 0.354 x Micronaire value · Micronaire value = 2.824 x Denier YARN COUNTS: It is broadly classified into 1. DIRECT and 2.INDIRECT system. DIRECT SYSTEM: · English count (Ne) · French count(Nf) · Metric count(Nm) · Worsted count · Metr...
