Non-Preferential Origin Rules Deciding Where Linen Cloth Was Made
Non-preferential origin of woven linen fabric attaches permanently to the loom shed site where yarn transforms into cloth under HS 5309.
Continuous Bleaching Softening
Chemical Treatment
Wet finishing stages for woven linen include a sequence that modifies both the color and the handle of the greige cloth. Adoption of continuous bleaching softening allows a mill to process large volumes of fabric through chemical baths at a steady pace. Automated machinery replaces older batch methods to ensure uniformity in whiteness and texture across thousands of meters of textile.
Process Flow
Fabric enters the range under tension and moves through an alkaline scour before reaching the oxidative bleaching zone. The continuous bleaching softening equipment applies a peroxide solution that removes natural pigments while maintaining the cellulosic integrity of the flax. Mechanical rollers guide the cloth through a series of heated compartments where the temperature is held at eighty degrees Celsius to accelerate the whitening effect.
After the bleaching phase, the material undergoes a series of high pressure rinses to strip away residual chemicals and prevent yellowing during storage.
Surface Effect
Finishing agents are applied in the final stage to reduce the natural stiffness of the linen. Because continuous bleaching softening integrates the application of softeners into the main line, the fabric emerges with a supple hand. Proper concentration of these agents prevents the oily residue that can interfere with later printing operations.
