How to iron Polyester fusible interlining correctly?

Proper ironing of Polyester fusible interlining is an important step to ensure that it adheres effectively and maintains the quality of the garment's appearance. Polyester fusible interlining is widely used in garment construction to provide structural support to the fabric and effectively prevent stretching and deformation. In order to ensure that the fusible interlining can adhere firmly to the fabric and perform its intended function, the ironing process requires special care and precision.

When ironing fusible interlining, it is critical to choose the right iron temperature. Generally, fusible interlining is suitable for ironing at medium temperatures, and high temperatures, especially above 150°C, are avoided to prevent the adhesive from melting excessively or damaging the fabric after melting. Many irons have a temperature setting for synthetic fibers that is suitable for ironing fusible interlining, so the temperature can be adjusted according to the temperature control of the iron. If you are unsure, you can first test a small area in an inconspicuous area to confirm that the ironing temperature is appropriate.

When preparing for the ironing job, make sure the surface of the ironing board is clean and free of moisture. Dirt and water stains can affect ironing and may even cause uneven bonding of the fusible interlining. If possible, use a fabric protector designed for irons to prevent the iron from coming into direct contact with the material and reduce damage to the fabric from high temperatures.

It is also very important to position the fusible interlining correctly. Place the fusible interlining with the shiny side (the adhesive side) facing down on the back of the fabric. Make sure the fusible interlining is aligned with the fabric to avoid wrinkles or shifting. By making sure the shiny side is in contact with the back of the fabric, the fusible interlining will bond evenly to the fabric during ironing.

Ironing requires great care. Gently place the iron on the fusible interlining, making sure to use moderate pressure. Excessive pressure may cause the adhesive to overflow or cause the fabric to deform. It is best to hold the iron on the fusible interlining for 5 to 10 seconds each time to ensure that enough heat can penetrate the material and achieve the desired bonding effect. Avoid moving the iron back and forth while ironing, as this may result in uneven ironing and unnecessary friction.

Ironing should be done gradually, in small areas, to avoid covering the entire fabric at once. Make sure each area is ironed long enough and do not overlook certain areas. After completing one area, check that it is fully bonded before moving on to the next section.

After ironing, allow the fabric and the Polyester fusible interlining to cool for a few minutes. Cooling is a key step in curing the adhesive and ensuring that the Polyester fusible interlining is firmly attached to the fabric. Cooling prevents the material from shifting due to touch if it is overheated. After cooling, gently pull the fabric to check that the Polyester fusible interlining is firmly bonded. If you find that the bond is not good in some areas, you can use the iron again to gently iron to ensure that the bond is strong.
