What does a sewing worker in a clothing factory mean?

The hemmer in a garment factory means that the garment factory is responsible for hemming clothes.

"hemming" is also called "hemming", which is a garment industry term, and English is "hemming". In the process of clothing production, because polyester and other materials are generally synthetic fibers, the silk thread at the edge seam of clothing materials will be scattered because of the high hardness after cutting, so it is necessary to copy the edge: use a special edge copying machine to copy a circle of edges at the edge seam to prevent the silk thread in the cloth from being scattered. This also plays an aesthetic role.
