mauve cotton fabric

Use 5-10ml/L 38° caustic soda, 1-2ml/L thermal stability dispersant and 3-5g/L insurance powder for treatment, and add 0.5-1g/L anthraquinone powder as an indicator. If the insurance powder and caustic soda are sufficient, anthraquinone will turn the color stripping solution red; if the color stripping solution turns yellow or brown, caustic soda and insurance powder must be further added. The fabric should be thoroughly washed after color removal.

When comparing rayon vs cotton it really depends on what you are looking for in a fabric. Rayon has a luxurious feel to it but tends to be less durable than cotton. Cotton has a more rugged feel but is much more durable than rayon. If you're looking for something with a softer feel then rayon may be the better choice, but if you're looking for something more durable then cotton would be the better option.
