Kilos in against Metres out at a Jiangsu Mill Audit
Reconciling raw European flax dry mass against finished fabric metres out exposes certified fiber dilution, protecting buyers from origin fraud in Jiangsu mills.
Reed Density Calculation
Weave Calculation
Mathematical determination of the number of dents per unit of length in a loom reed establishes the horizontal spacing of the warp threads. The reed density calculation involves dividing the total number of warp ends by the effective weaving width of the cloth. This value dictates the fineness of the weave and the final weight of the linen fabric per square meter.
Design Interaction
Weavers must account for the shrinkage that occurs after the fabric is removed from the loom and subjected to finishing. A precise reed density calculation ensures that the finished cloth meets the buyer’s specifications for thread count and width. The choice of reed also affects the degree of abrasion the yarn experiences, as too many threads in a single dent can lead to pilling or breakage.
Formulas for this determination include factors for the crimp and the expected contraction of the flax yarn.
Production Accuracy
Errors in this measurement result in fabric that is either too narrow or lacks the required structural density. Once the reed density calculation is finalized, it is recorded on the loom sheet to guide the setup of the machine. This step is a fundamental part of the technical planning process in any professional weaving mill.
