Product Identification
Visual coding methods apply distinct colours or printed symbols to the inner carriers of wound yarn to prevent different grades from being mixed during packing and shipping. Through yarn cone marking, spinning mills ensure that operators can instantly identify the yarn count and composition of a specific bobbin before it is packed. This system is necessary in facilities that process both conventional and organic linen yarns simultaneously.
By using colored paper inserts or printed barcodes on the inside of each plastic tube, the mill maintains a clear visual reference that persists throughout the weaving and finishing stages.
Code System
Mills assign unique color combinations to represent specific yarn thicknesses and blending ratios. When applying yarn cone marking, the marking machines stamp a batch code and the yarn count on the inner rim of each cone automatically. This systematic coding allows weavers to load the correct yarn onto their looms without risking mixed-density defects.
Quality Control
Quality inspectors check the printed markings against the daily production sheet to confirm that the labels match the physical test results. Any error in yarn cone marking results in the immediate isolation of the affected batch to prevent incorrect shipments. This attention to detail protects the mill from customer complaints and returns.
