Linear Density
Indirect measurement units that define the fineness of linen threads represent the number of three-hundred-yard cuts of yarn contained in one pound of weight. In the international linen trade, yarn lea count acts as the standard metric for specifying yarn thickness. A higher count indicates a finer yarn, which is used to produce delicate apparel fabrics, while a lower count indicates a coarser thread suitable for heavy canvas or household upholstery, with the entire pricing of the linen yarn structured around this fundamental metric.
Spin Calibration
Spinning mill operations are organized around achieving the target thread thickness requested by the buyer. To spin a specific yarn lea count, technicians adjust the draft settings and water temperature on the wet spinning frames to draw the flax sliver to the required density. Daily quality control checks measure the weight of a standard length of yarn to ensure the spun product complies with the contracted count specifications.
Weaving Application
Weaving preparation on high-speed looms requires selecting yarn of the correct fineness to achieve the desired fabric weight. A high yarn lea count is essential for light apparel linen. Mill managers use this count to calculate yarn requirements before starting the loom.
