Pure cotton clothes are a common choice for our daily wear, but dyeing problems often trouble people. To solve the dyeing problem of pure cotton clothing, we first need to understand the cause of dyeing.

2. Dye is not fast: The fastness of dye refers to the firmness of the combination of dye molecules and fibers. Some dyes may lose their binding ability under certain conditions, making them prone to falling off and staining other clothing items. This situation is usually more common with newly purchased clothing.

2. Classified washing: When doing laundry, wash pure cotton clothes in categories with other clothes of similar colors to avoid washing clothes of different colors together. Cotton clothing is best washed separately to prevent dye migration.
3. Washing in cold water: Washing pure cotton clothes in cold water can reduce the dissolution and migration of dyes. High-temperature water will accelerate the fading and migration of dyes, so try to wash in cold water.
4. Dry in the proper airspace: When drying pure cotton clothes, avoid direct sunlight exposure, which may cause the dye to fade and the clothes to deform. Choose a well-ventilated place to dry and try to avoid friction and squeezing.
5. Professional stain remover: If pure cotton clothing is stained with other colors or dyes, you can choose to use professional stain remover to deal with it. Before use, test a small area in a hidden area to make sure it won’t cause more damage to the clothing.
6. Regular inspection: Regularly check the color of pure cotton clothing for fading or dye migration. If you find a dyeing problem, take corrective measures in time to avoid further expanding the scope of dyeing.

Through reasonable care and correct operation, the occurrence of dyeing problems of pure cotton clothing can be reduced and the service life of the clothing can be extended.
