Pectin Dissolution Dynamics in High Speed Wet Spinning Troughs
High-speed wet spinning demands sub-second pectin dissolution achieved through micro-jet boundary layer disruption and controlled calcium chelation.
Yarn Linear Density Mass CV%
Mass Variation
Consistency of a spun material is quantified using statistical quality metrics that represent the variation in weight. Calculation of the yarn linear density mass cv% allows the mill to quantify the consistency of the flax yarn produced on the spinning frames. A lower percentage indicates a more uniform product that will appear smoother in the finished woven fabric.
Weaving Performance
Strength of the yarn is often limited by the thinnest points along its length. Because a high yarn linear density mass cv% indicates many such weak spots, the yarn is more likely to break under the tension of a high speed loom. Controlling this variation is essential for maintaining the efficiency of the weaving department and reducing the number of knots in the final cloth, which improves the overall surface quality of the linen.
Testing Protocol
Electronic capacitance sensors measure the mass of the yarn as it passes through a testing head at high speed. The resulting data allow the technician to identify specific faults in the spinning machinery, such as worn rollers or uneven drafting belts, which assists in maintaining productivity. Frequent testing ensures that every lot meets the technical specifications listed in the buyer’s contract.
