One common mistake is choosing interlining based only on GSM. Although weight matters, construction, coating, flexibility and compatibility with the fashion fabric also influence performance. Another mistake is skipping the sample stage because the supplier has provided a technical specification. A material can meet its stated GSM while still producing an unsuitable hand-feel or bond when fused to a particular fabric.
Factories can avoid many of these problems by evaluating fusible interlining suppliers systematically. They should test the actual material, document the approved specification and confirm the supplier’s ability to provide the same grade repeatedly. For interlining for suit manufacturer applications, it is also important to consider where the interlining will be applied and how much structural support that section requires. Treating interlining as a technical component rather than a basic accessory can improve consistency and reduce avoidable production problems.
