How can we ensure a strong and even bond between woven fusible interlining and fabric to avoid bubbling or debonding?

In order to ensure that the bond between the Woven fusible interlining and the fabric is strong and uniform, and to avoid blistering or degumming, we need to follow a series of key process steps and precautions. Here are some suggestions to help us achieve the ideal bonding effect in actual operation:

1. Material selection and preparation
Matching of interlining and fabric: Choose interlining that matches the material, thickness and texture of the fabric. For example, high-end clothing crafts should use Woven fusible interlining with good elasticity and high adhesion.
Fabric pretreatment: For fabrics that have not been pre-shrunk at high temperature, margins should be left around when cutting to prevent the size of the garment pieces from shrinking after the fabric is bonded at high temperature.

2. Interlining cutting and preparation
Cutting direction: When cutting interlining, the same yarn direction as the garment pieces is usually used. However, for high-end clothing, it is best to use 45° bias yarn cutting to increase elasticity and stretchability.
Size adjustment: To prevent the adhesive of the interlining from sticking to the iron or bonding machine, the cut interlining should be 0.2~0.3cm smaller than the fabric around.
Softening treatment: Before bonding, gently soften the adhesive interlining by hand to improve its bonding performance.
3. Bonding operation
Temperature control:
When operating manually, the temperature of the iron should be controlled between 130~160℃ to prevent the adhesive interlining from degumming or bubbling of the garment pieces due to excessively high temperature, and the adhesive will not be firmly bonded if the temperature is too low.
When bonding by machine, the adaptable temperature of the fabric or adhesive interlining should be determined first to avoid scorching, shrinking or degumming of the fabric.
Pressure and time: According to the specific materials of the adhesive interlining and fabric, adjust the pressure and bonding time of the bonding machine to ensure uniform and firm bonding.
Operation sequence: For parts with a large bonding area (such as the front garment piece), it is best to perform point welding first, start bonding from the middle, and then gradually spread to the surrounding areas.

4. Post-bonding treatment
Cooling and shaping: The bonded garment pieces must be laid flat and cooled before the next process can be carried out to prevent deformation of the garment pieces.
Quality inspection: After bonding, carefully check whether the garment pieces have bubbling, degumming or uneven bonding, and deal with any problems in time.

5. Equipment maintenance and care
Regular maintenance: According to the equipment maintenance requirements, regularly oil and maintain the bonding machine to ensure that the machine is in the best working condition.
Cleaning work: Wipe the machine frequently to keep it clean to avoid contaminating the fabric.

Through careful selection of materials, preparation, operation and post-processing, as well as equipment maintenance and care, we can effectively ensure that the bonding between the woven fusible interlining and the fabric is firm and uniform, avoiding blistering or degumming.
