AIM: to observe the local hemostasis, analgesia, anti-infection and healing effects of multifunctional wound dressing based on isobutyl-chitosan, which is derived from chitosan.

Chitosan fiber can be used to prepare medical dressing, human body absorbable suture, support material for tissue engineering etc., but its lower tenacity greatly hinders its application area.

In this paper wound bandages with mixed chitosan fabric were designed which adopted woven double-faced structure and knitted jacquard-rid weave separately.
