Warp Sampling and Colour Arrangement Verification
topic
Warp colour arrangement verification uses visual inspection of the wound section or beam cross-section and digital colour detection systems that scan the yarn arrangement across the beam width, comparing detected colour sequence against the programmed colour order and flagging deviations from the specified pattern that would cause colour sequence errors in the woven fabric stripe or check pattern.
Role
Prevents the costly fabric defect of incorrect warp colour sequence that makes the entire warp length unusable for the intended pattern repeat, catching creel loading errors in sectional warping before beaming and enabling correction of colour sequence mistakes at the warping stage where correction cost is much lower than after sizing, drawing-in, and weaving have been completed.
