How to Prevent Bubbling When Using Non Woven Fusible Interlining

Bubbling is a common issue manufacturers need to investigate when applying non woven fusible interlining to garment fabrics. It appears as raised areas or uneven patches between the outer fabric and the interlining, affecting the finished garment's appearance. Rather than assuming the interlining itself is defective, production teams should review fabric compatibility, preparation and the fusing process to identify the likely cause.

One important factor is the combination of temperature, pressure and application time. If the adhesive does not activate adequately, the bond may remain weak or uneven. Excessive heat can also affect sensitive outer fabrics, potentially changing their appearance or causing distortion. Manufacturers should follow the supplier's recommended conditions for the specific grade and equipment instead of applying one setting to every material. Fabric preparation matters too: moisture, creases or an uneven pressing surface can interfere with consistent contact.

The next step is to conduct a controlled sample test. Cut the actual production fabric and the selected non woven interlining fabric to matching sizes. Apply the recommended fusing conditions, allow the sample to cool completely and inspect the surface under good lighting. Check whether the bond is even across the piece, paying particular attention to edges and corners. If bubbling occurs, change one variable at a time during further trials so the team can determine whether the issue relates to the grade, fabric or application conditions.

Before moving to bulk production, record the approved interlining specification and fusing settings for each relevant fabric combination. Repeat testing when the outer fabric's weight, finish or composition changes. Double Ghoda supplies non-woven interlining grades for garment components such as collars, cuffs, plackets and pockets. Buyers should select a suitable grade based on the intended application and confirm performance through sampling. A consistent testing procedure helps reduce avoidable defects and supports better quality control across production runs.
