Yarn Production
Processing of long, continuous flax fibres is the primary method for creating fine, high-tensile linen yarns. Mills utilize line flax spinning to produce premium yarn counts that are suitable for high-grade warp threads in apparel weaving. This methodology utilizes parallelized fibre bundles that have been hackled but not broken into short tow.
Mechanical Processing
Drafting and wet-winding are executed on specialized frames where the long fibers are drawn through hot water to soften the binding pectins. Because line flax spinning demands exceptional fiber alignment, the roving undergoes multiple doublings on draw frames to ensure uniformity. The production log records the twist multiplier and draft ratio to verify that the spun yarn meets the target strength requirements.
Fine yarns produced this way are wound onto perforated bobbins for bleaching or immediate dyeing. This processing stage represents the highest capital investment in the spinning mill, requiring precise humidity controls to keep the fibers pliable.
Fabric Output
Strength profiles of yarn made from long fibers allow it to withstand the high tension of modern weaving looms. In contrast to tow yarn, the output of line flax spinning yields smooth, lustrous fabrics with minimal hairiness. Acceptance criteria for export-grade linen require these fine yarns to have a low coefficient of variation in both diameter and tensile strength.
