Dark lining shades are worth checking carefully because colour transfer can be particularly noticeable when the dye marks a contrasting light fabric. Manufacturers sourcing polyester lining fabric for suits, jackets, sherwanis and other garments should evaluate each intended shade before approving bulk quantities. Black, navy and maroon may be especially relevant when the finished garment contains pale layers. However, shade alone does not determine performance. Dyeing, finishing, fabric construction and processing can all influence the result, so buyers should test the actual material rather than assume that every dark shade will bleed.
Colourfastness screening for polyester lining can include dry rubbing, wet rubbing and washing tests. In a rubbing test, use a clean white cloth and apply consistent pressure to the lining's surface. Check the cloth for colour transfer, then repeat with a damp cloth. For washing, stitch a sample to white fabric and follow the intended garment care instructions. Compare the lining with an untouched piece after drying and inspect the white fabric for stains. Run the checks on each colour and relevant dye lot, particularly when a garment combines contrasting materials. If a buyer requires a specified colourfastness grade, use the agreed test method rather than relying solely on visual screening.
Keep the results with your purchasing records and retain a reference sample for comparison with later deliveries. If colour transfer or fading appears, investigate the lot before authorising production. Consider other processes, including pressing and dry cleaning, when they form part of the garment's care requirements. The Double Ghoda polyester interlining category lists several lining varieties that wholesale buyers can explore. Product information can help narrow your options, but it does not replace colourfastness verification. Request samples and assess the intended shade against the materials and processes used in your own garment production. This helps establish a more dependable approval process for dark and contrasting lining colours.
