aSeed flax straw was grown in North Dakota, USA in 1999. Ariane was grown optimally as a winter crop in South Carolina, USA, 1999, for fiber (early) or to maturity for seed (late).
bThe top value in each column is a 50/50 blend of flax and cotton. The bottom number in each column is a 90/10 cotton/flax blended yarn. The flax was commercially cleaned through the Unified Line and LaRoche cottonization systems.
