Buying interlining in large quantities without testing it first can create expensive production problems. Before ordering non woven fusible interlining, manufacturers should confirm that the material works with their actual shirting fabrics and machinery. Product specifications such as GSM and coating type provide useful information, but a physical test offers a much clearer indication of how the material will perform. The sample should be fused using the same temperature, pressure, and dwell time planned for production.
A proper evaluation of non woven interlining fabric should include several checks. After fusing, inspect the surface for bubbling, wrinkles, strike-through, or uneven adhesion. Flex the collar or cuff to see whether the material moves naturally rather than cracking or becoming excessively stiff. A wash test can then reveal whether the bond remains intact. Manufacturers should also compare colour, roll length, and hand-feel between batches when reordering. These checks take little time compared with correcting hundreds of defective garments. Working with a supplier that maintains consistent GSM, coating, and roll specifications can further simplify quality control.
