45rpm RAW DENIM




At 45rpm, we are known for the variety of garments we offer in indigo or ai-dye.
When we use the term indigo here, we are referring to an aniline or synthetic indigo dye. In aniline indigo dyes, the dye molecule mimics that of natural plant indigo; a large molecule that does not penetrate the fibers, but sits on top of it, hence the crocking or bleeding that people need to be aware of and at the same time, that which offers us a more beautiful faded blue with wear and use.
All of our indigo-dyed garments are yarn dyed by machine, not garment dyed, in order to achieve a rich dark blue color. Indigo-dyed items fade beautifully over time, and our denim products dyed with Indigo especially age well with a high contrasting color between the blue dye and the white of the yarn.
When we refer to Ai-dyed items, we are talking about a Japanese natural plant dye. Garments which are Ai-dyed at 45rpm are always yarn-dyed by hand. For example, with Ai-dyed denim, the skeins of yarn are dyed twice a day for two weeks to achieve their fullest color.
Ai-dyed garments tend not to fade in the same way the aniline indigo items do. Ai-dyed clothing tends to fade more evenly, and the color becomes a softer hue of blue rather than the chiaroscuro effect achievable in the indigo-dyed items.
