► Tween 40 is proved to be an effective inner antistatic agent for PP. ► A combination of T40 and cationic PP has improved the washing durability of antistatic PP. ► The modified T40 accumulated on PP surface is immobilized by UV crosslinking. ► Antistatic PP with washing durability is prepared by blending 1% MT40.
