What causes “swirl” or “moiré” marks on garments after pressing on a new press pad, and how do you fix this problem?
This problem is normally noticed on lighter fabrics, such as rayon. The reason for this occurrence is due to too much steam pressure coming from the top of the press. The top steam pressure should be shut off or reduced for about 3 weeks. As a press gets older the holes at the head of the machine get wider as well. More steam starts to flow from it. Because a new grid plate will function more efficiently, due to the fact that materials are more “breathable” and there is less starch, sizing or chemical build-up, the grid plate doesn’t need as much top steam to press. After about 3 weeks when the press pad isn’t as new, the top steam can be increased as necessary.
