Muto Dyeing/Window of the Drying Tower

A dyeing factory in Hamamatsu City, Shizuoka Prefecture. The plant has a tower-shaped drying area remarkable even among nearby plants, with a ceiling of approximately 9.5 m high. The fabrics dyed on the lower floor are hung on the rods in the drying area and then raised using a pulley. This drying method is known as “loop drying” and requires less than an hour in the dry air of winter. The walls are lined with FRP corrugated sheets, resulting in heat accumulation similar to that in a greenhouse. The double-sliding aluminum sashes above, which cannot be reached by hand, are opened and closed from below with a cord.
