Fiber Mixture
Composite yarn produced by combining bast and seed fibers offers a balance of physical properties that differs from either component alone. The use of a flax cotton blend reduces the stiffness of pure linen while retaining its characteristic texture. Combining these fibres requires careful selection of the relative proportions to ensure a stable yarn structure during downstream processing.
Spinning Modification
Cotton-system machinery is adjusted to process the longer and more variable flax fibers alongside the shorter cotton staples. The flax fibers must undergo cottonization, which involves chemical or mechanical shortening to match the length of the cotton fibers before they can be blended. Spinners adjust the drafting roll settings to prevent fiber bunching and ensure an even distribution of the two fiber types.
Commercial Benefit
Blending these fibers allows manufacturers to offer fabrics that are easier to iron and softer to the touch than pure linen sheets. The composite fabric dyes more uniformly because the two fibers absorb dyestuffs under similar chemical conditions, although they exhibit different lustre levels. This mixture reduces raw material costs for fabric mills while providing the market with a textile that combines the moisture absorption of flax with the easy care of cotton.
