According to literature from Nature Science, a portion (approximately 40%) of the many chemical dyes utilized in industrial dyeing and finishing contain carcinogens such as phthalates, formaldehyde, perfluorinated compounds (PFCs)…and more that are harmful for both humans and the environment.
This material is produced from persimmon fruits discarded by farmers after thinning. The dye is extracted through processes such as squeezing, filtration, and fermentation. Due to the content of tannic acid and pectin in persimmon dye, it can be shaped through the sticky characteristic of pectin. This cotton fabric is produced by techniques such as dyeing and sun exposure to oxidize the tannic acids on the persimmon dye fabric, giving it a reddish-brown color. Finally, the fabric’s color is set with iron acetate (mordant).more
