The fabric interwoven with cotton of acetate filament is soft and smooth to the touch and can be used to produce high-grade fabrics.Acetate and cotton fabrics were dyed with different dyeing sequences and processes,and the K/S value and the color fastness to soaping and rubbing were tested to explore the best dyeing process.The results show that the best process is as follows:dyeing acetate → reduction cleaning → dyeing cotton → soaping,and the color fastness to soaping and rubbing can reach 4~5 grade.
