In order to solve the problem that ordinary fabrics are too soft and not stiff enough, a layer of adhesive lining or auxiliary cotton with glue is usually attached to the back of the fabric. However, if ironing and bonding are not effective, there will be some problems such as adhesive peeling and foaming on the surface of the fabric. How can we iron the adhesive lining smoothly and suitably? Today we will mainly introduce the most practical ironing method for curtain lining.
1. Ironing Temperature
Whether it is adhesive lining or cotton with glue, one side of them is attached with hot melt adhesive. Hot melt adhesive has its melting point. If the temperature is too low, it will not melt or completely melt, and if the temperature is too high, it will cause the sublimation of the gum to lose its viscosity. In general, the ironing temperature of the adhesive lining should be controlled between 120 ℃ and 150 ℃. The temperature of the thin lining can be adjusted lower than that of the thick lining.
2. Ironing Pressure
In addition to controlling the appropriate temperature, it is necessary to apply appropriate pressure to the adhesive interlining to make it fully bonded to the fabric. Therefore, when ironing the adhesive lining, we should not use sliding-ironing as usual, we should apply vertical pressure to the clothes iron. The pressing force is determined by the thickness of the fabric. The pressure of the thin material should not be too large. Too much pressure will cause the sol to penetrate the front of the fabric and affect the appearance. Conversely, you can press the iron a bit heavier when ironing thick fabrics.
3. Ironing Time
The ironing time is generally 5 ~ 8 seconds, if the time is too short, the melted glue will not melt, if the time is too long, it will cause the gel to penetrate or sublime.
The above three elements are also interactive. If the ironing temperature is too high, the pressure and time can be reduced appropriately. If the temperature is low, the pressure and ironing time should be increased.
4. Ironing Method
Ironing adhesive lining is generally cloth under lining. Before bonding, iron the fabric flat with the reverse side facing up, then lay the adhesive lining. The ironing position should gradually spread from the middle to the surrounding edges. As mentioned earlier, the method of sliding ironing cannot be taken, that is, the iron cannot be slid on the adhesive lining, but should be ironed "one step at a time".
Specific method: Hold the iron vertically and apply a certain pressure downwards. After staying in a position for 5 ~ 8 seconds, pick up the iron and put it in the next position and stay for 5 ~ 8 seconds. Between the first position and the second position, there should be no gaps, it is better to overlap a part. After ironing, the cloth and adhesive lining must be cooled before moving to the next step.
Because the cotton layer is thicker, the heat transfer will be hindered relatively. So we can take the method of lining under the cloth during ironing. For some auxiliary cotton without seam allowance (the circumference is smaller than the fabric), it is difficult to align the cloth on the top. At this time, we can first make the auxiliary cotton be slightly bonded on the top and then turn it over to do formal ironing and bonding.
5. Whether to Use Steam
Some adhesive linings are easier to bond under certain humidity conditions. Usually, the adhesive linings with dotted distribution of melt adhesive can use steam. Double-sided hot melt adhesives can also use steam. If you are not confident in your own bonding method, you can use some scraps for trial ironing.
