Q: Why is my zipper deformed after garment pressing?
Pressing applies heat and pressure directly to the tape and teeth, and most moulded elements have a temperature above which they soften permanently. Deformation that matches the press footprint is therefore a process issue rather than a zipper defect.
- Note the iron or press temperature and whether steam was used directly on the zipper.
- Check whether the deformation is local at a pressed area or along the whole length.
- Compare with a sample kept away from the press.
- Check the care label and the maker's ironing guidance for the zipper type.
- Try a lower temperature with a cloth barrier on scrap and compare.
Deformation at the press footprint is corrected by lowering the temperature and avoiding direct pressure on the chain. Deformation out of the pack is a maker issue. Keep the temperature record, since it is the evidence that decides the claim and prevents the same setting from being used on the next order.
