How do the traditional dyeing techniques used in Indian textiles, such as tie-dye and block-printing, impact the chemical stability of the fabrics?

Traditional dyeing techniques like tie-dye and block-printing impact the chemical stability of fabrics through their use of natural and often less reactive dyes. For instance, tie-dye uses resist techniques to apply dye selectively, which can enhance the longevity of color on fabrics. Block-printing involves applying dye with carved wooden blocks, allowing for precise color placement and reducing the risk of chemical reactions that might degrade the fabric. Natural dyes, such as those derived from plants, often have better chemical compatibility with fabrics, resulting in vibrant, long-lasting colors that are less likely to fade over time.
