Abstract: The reasons for the poor wet rubbing fastness of lyocell fabric were explored. The paper compared the influence of different fiber opening processes on the wet rubbing fastness and put forward the feasible scheme to improve the wet rubbing fastness of lyocell fabric from the perspective of reducing loose color and reducing the shedding of short fluff on the fabric surface.

Key words: lyocell fiber; fastness to wet rubbing; fibrillation; short fluff
