PURPOSE: A dyeing material using loess is provided which is characterized by having resolvability and self-purification capacity, being porous, radiating far infrared ray, having adhesion, promoting health because of removing toxin of skin, and being useful for cotton. CONSTITUTION: A dyeing method of the loess dyeing material is as follows: cationizing cellulose fiber to increase dyeability; dyeing a mud yellow over the cationized fiber with the dyeing material; washing and drying in the shade; dipping the dyed fiber for 24hours into 3% of FeSO4 solution to maintain the color; and then post-finishing to increase color fastness. The loess dyeing solution is obtained by a process containing the steps of: filtering through 60μm of a sieve; mixing 400g of loess based on 1l of purified water; leaving at normal temperature for two weeks; and then make the solution having pH4-5. |
