Simply under-fused : Glue did not get into fabric yet. Simply fused it again.
         Over-fused : Glue is all gone, can not save the garment, unless rip -off interlining and fuse another one.
        Glue does not hold to the fabric : Interlining is not suitable.
        Too much heat shringkage: Can be avoided by pre-production testing
        Partial delimitation : Someone touched fused area while it's warm
        Bubbling found after wash : because bond strength is not enough, Differential shrinkage between fabric and interlining is excessive. Could be avoided by pre-production wash test.

        This above only a guide and not for a final evaluation.
        Plus factor of using ISA interlining: Economical to use, easy to sew, keeps desirable stiffness and retains original Shape after repeated washing.

   Improvement of Garments quality.
        Soft handling, as s oft natural handle, Fine silhouette, Shape Stability, Aesthetic shaping.

   Excellent bonding strength and controlled shrinkage. Durable in water washing and  excluding:  temporary fusing type.

Using interlining in garment to ensure stable appearance of finished products, to meet wash-wear standard, give more comfortable and softer collars, cuffs, button holes  etc...

No deformation after pressure and washing controlled proportion of Shrinkage after  many times of washing.

No deformation after iron controlled proportion of shrinkage at high temperature.
