Dyes are colored substances that have the ability to bind to materials and impart them with color. In contrast to pigments, which only reside on a material's surface, dyes physically or chemically bind to the threads or molecule they color. As a consequence, the coloring is more resistant to fading and washing.
Types of Dyes in Clothing :
1.Natural dyes: Extracted from plants, animals, or minerals. Generally considered safer for health and the environment, but have limitations in color range and wash fastness.
2.Synthetic dyes: Derived from chemical processes. Offer a wider variety of colors and better wash fastness, but some may raise environmental or health concerns.
3.Azo-free dyes: A specific category of synthetic dyes that excludes potentially harmful aromatic amines, making them a safer alternative.
What are Non-Toxic Dyes:
Defining "Non-Toxic" dyes can be tricky, as it's a subjective term and there's no single standard. However, when discussing non-toxic dyes, there are two main interpretations:
Dyes free of harmful chemicals:
This primarily refers to the absence of carcinogenic aromatic amines found in some azo dyes. These break down and release potential health risks. Additionally, it considers the absence of heavy metals and other toxic chemicals used in some dye production and disposal processes, which can harm both human health and the environment.
Dyes with minimal environmental impact:
This goes beyond just the chemicals in the dye itself and considers the entire dye lifecycle. It includes dyes produced using sustainable practices and renewable resources, with minimal water usage and pollution during production and disposal. It also considers the dye's biodegradability and whether it breaks down readily without leaving harmful residues.
A truly "non-toxic" dye would ideally meet both criteria, being free of harmful chemicals and minimizing environmental impact, like Natural dyes and Azo-Free dyes. Remember, it's important to research and understand the specifics of each dye and its manufacturing process before labeling it "non-toxic." Consider certifications like Oeko-Tex Standard 100 or GOTS for the guaranteed absence of harmful substances. We TinyKiddo, has the GOTS certification that clearly mention we use Non-Toxic Dyes.
