Weave Structure
Fabric density measurements record the number of weft yarns inserted into a single centimeter of the cloth length. In the weaving specification, picks per centimeter determines the weight and the drape of the finished linen, and this value is controlled by the take-up motion of the loom which pulls the fabric forward after each yarn insertion.
Production Control
Weavers adjust the electronic settings of the loom to achieve the required pick count for a specific design. If the loom speed increases without a corresponding adjustment in the take-up the density will fluctuate. High picks per centimeter results in a stiff and durable fabric while a lower count produces a lighter and more flexible material.
The natural variation in the thickness of flax yarn makes maintaining a perfectly even count a technical challenge. Monitoring the tension of the weft yarn during insertion helps in achieving a uniform density across the bolt.
Inspection Protocol
Grading reports include the pick count measured at the start, middle and end of each fabric roll. If the count falls outside the agreed range the fabric may be rejected for failing to meet the weight specification. This data is essential for calculating the total yarn consumption and the cost of production for large export orders.
