Flax Fiber Chemical Composition and Basic Retting Quality Evaluation
Optimal retting reduces residual pectin below 1.8 percent, allowing ultimate fiber separation to 3 tex and maximizing high-count line yarn yield.
Predicting Non-Linear Fiber Bundle Jamming and Chemical Extraction across Variable Flax Retting Grades
Residual pectin above 3 percent prevents fiber bundle flattening, inducing premature mechanical yarn jamming that cuts rapier loom efficiency by 19 percent.
Mechanistic Coupling between Moisture Regain and Dynamic Bending Energy Dissipation in Bast Fiber Structures
Moisture plasticizes the amorphous pectin matrix in bast bundles, lowering yarn flexural rigidity while elevating cyclic bending energy dissipation.
Flax Fibre Non Cellulosic Content Impact on Hackling Yield
Non-cellulosic content above 3.5% lowers hackling line yield, increasing tow waste and landed line fibre cost per finished metre.
