Producing Wound Dressing Materials from Chitin Derivatives by Forming Nonwovens Directly from Polymer Solution

Abstract

Dibutrylchitin is an ester derivative of chitin, characterised by good biomedical properties. Therefore, it can be used as a raw material for wound dressings. The high solubility of dibutyrylchitin in common organic solvents allows to transform it into fibres, and next final fabrics. Technologies of the forming of nonwovens directly from polymer allow to decrease the cost and rate of waste. Two methods of nonwoven production from dibutyrylchitin are described in this paper: the forming of nonwovens by the spraying of polymer solution and the electrospinning of polymer solution. The cytotoxicity and irritation effect of nonwovens made by electrospinning technology was investigated.
