What are the "fulling" and "hard finish" mentioned in the fabric description for?
When reading the coat's description, unfamiliar expressions appear, stating that it was fulled multiple times in a Hemmer fulling machine and went through a hard finish. It makes one wonder why a wool coat undergoes these processes.
They are finishing processes intended to densely interlock the fabric's structure and firmly set the surface, reducing wrinkles and helping the coat retain its shape for a long time.
Fulling is a process that applies moisture and pressure to wool fibers to shrink the woven structure and cause it to interlock densely. By narrowing the gaps between threads and increasing density, it serves to compact the fabric surface into a smooth and uniform state.
ARTS&SCIENCE's Bal collar coat is crafted from 100% Superfine ZQ-certified Merino wool of 18.5 microns from New Zealand[1][2]. After fulling the twill flannel fabric, woven from 2-ply ultra-fine worsted yarn, multiple times in a Hemmer fulling machine, the surface fuzz was sheared off and a hard finish was applied[3][4]. This is a finish intended to prevent wrinkles from forming easily and to maintain the coat's neat shape and durability[5].
hmmm, this reads as a deliberate choice to preserve softness while alleviating concerns about frequent wrinkling by adding repeated fulling and a firm finish to delicate worsted flannel.

The specific number of fulling cycles undergone in the Hemmer fulling machine and the detailed processing method used for the hard finish have not yet been confirmed.
