What changes does the 'SY processing' mentioned in the cap's description make to the fabric?
I read the description stating that vintage processing was added to a cap made of functional fabric. I asked out of curiosity about why this processing was applied to a sweat-wicking material.
It is a vintage processing that transforms a functional polyester fabric, which vents sweat through microscopic ventilation holes, into a thick and soft texture like sun-dried natural fibers.
While its function is close to sportswear, the feel against your hands is as natural as everyday clothing fabric. The fabric used in meanswhile's shade cap is Dot Air, a multifunctional polyester material that vents moisture and stuffiness through microscopic ventilation holes created with special technology[1][2]. Typically, synthetic fibers with excellent breathability have a slick surface and sheen, strongly giving the impression of sportswear.
What was added to this is the SY processing[3]. It is a vintage processing method that relieves the taut tension of fibers and creates fine wrinkles and microscopic unevenness to make the surface supple. Through this processing, meanswhile loosened the grain of the synthetic fibers and realized a thick and soft touch like natural fibers dried thoroughly in the sun[4].
hmmm, it amounts to tuning the fabric's texture so that it blends naturally into everyday outfits while retaining the performance of an outdoor cap that vents sweat.

Whether the thick and soft texture achieved through the SY processing is maintained as is even after repeated washing has not yet been confirmed in the official materials.
