It prepares fibres so that dyes bond securely, resulting in brighter colours and improved wash fastness while maintaining the natural softness of the material. Suitable for both cellulose fibres (such as cotton and linen) and protein fibres (such as wool and silk), alum is typically used as a pre-dye treatment. It allows natural dyes like madder, cochineal and logwood to develop clearer, more vibrant and longer-lasting shades.\u003c\/p\u003e\n\u003cp\u003eThis high-quality alum dissolves easily in warm water, ensuring consistent and reliable results across a wide range of dyeing methods.
