Fusible interlining is commonly used where garment manufacturers need additional support without sewing a separate reinforcement layer into place. Plackets are one such area because they contain buttonholes and receive repeated stress. A suitable interlining can help stabilise the strip and support a cleaner finish during garment construction.
Non woven fusible interlining consists of bonded polyester fibres with a thermoplastic adhesive coating. When the coated side is exposed to suitable heat and pressure, it bonds with the wrong side of the garment fabric. The result is a reinforced section that can be incorporated into the garment before stitching and finishing. Non-woven construction is particularly relevant for smaller garment components where a lighter support layer may be appropriate.
When buying non woven interlining fabric, garment manufacturers should first identify the fabric it will be fused to. Cotton shirting, blends and kurta fabrics can react differently during fusing, so a specification that works well for one material may not produce the same result on another. GSM should be assessed alongside fabric weight and the level of firmness required.
Sample testing should be part of the selection process. A small piece of the garment fabric can be fused with the proposed interlining using the production press or comparable equipment. The test should be checked for bond strength, surface appearance, stiffness and hand-feel. Any sign of bubbling, poor adhesion or excessive rigidity is a reason to reconsider the combination or the fusing conditions.
For bulk production, documenting successful test results can make sourcing easier. Record the interlining specification, garment fabric, fusing conditions and observed finish so the same combination can be reproduced when the garment returns to production. This is especially useful for factories handling multiple styles. Instead of selecting interlining solely by price or GSM, buyers can use actual fabric compatibility and production performance as the basis for their purchasing decision.
