Maintain combing halls at 70% RH and control pectin esterification below 58% to maximize high count line flax hackling yields and lower metre costs.
Wet-spun linen warps demand a minimum tenacity of 18.5 cN/tex with under 1.2% beaming stretch to maintain loom stop rates below 1.5 per 100,000 picks.
Trough water at 70°C hydrolyzes middle lamella pectins to permit inter-fibre slippage, enabling high mechanical drafts down to fine linear yarn counts.
Specify long-staple line flax and wet spinning in purchase contracts to prevent spinners from substituting short tow fibre into ambiguous metric yarn orders.
