What is the 'presser foot mark' mentioned in the cap description?
When choosing a hat, many people pause at the phrase 'presser foot mark' listed alongside scratches. This is because it is hard to tell whether it is an advance notice of a defect or a trace resulting from the manufacturing method.
It is a mark left by the sewing machine component that presses down on the fabric, and Centaur states that for both caps, it is not a defect[1][2].
A presser foot is a component next to the sewing machine needle that holds down the fabric from above. Because the fabric is pushed forward while pressed by this component as stitching proceeds, indentation marks or slightly shiny traces may remain where pressure and friction have passed.
Bio-washing is a process that uses enzymes to decompose fuzz and fiber ends on the fabric surface to create a soft touch. Since the surface is smoothed out by one layer, pressed or brushed traces tend to stand out relatively easily. This is also why Centaur mentions scratches alongside presser foot marks on the two products, CENTAUR BIG LOGO BALL CAP_IVORY and MORNING GLORY NYLON CAMP CAP_NAVY, clarifying that they are not defects[3][4].
hmmm, the fact that the same sentence is attached to two caps with different shapes and materials reads as meaning that this notice is not an explanation of a specific product's condition, but is closer to an advance notice about a common property that appears whenever fabric undergoes the bio-washing process.
We have not yet confirmed whether these marks fade with wear or washing.
