Abstract

The article highlights some significant trends in use of textile materials in medicine. The kinetics of swelling and drug release of composite wound dressing material in various pH buffer solutions has been studied by simulating the pH range of wounds. Composite dressing material is prepared by grafting #polyacrylic acid-co-acrylamide hydrogel on the cotton fabric using polyethylene glycol as cross-linking agent. Natural dyes have been extracted from camphor plant (#Cinnamomum camphora) dry leaves in alkaline medium and are then applied onto silk fabric by exhaust dyeing process. Properties such as ultraviolet protection, antimicrobial property, colour strength values, and colour fastness of the silk dyed using plant extract have been investigated. Over the past few decades, a number of research groups have been working on strategies to promote the wound healing process and the development of wound dressing materials. An ideal wound dressing should meet the following criteria such as debridement, retention of moist wound environment, low adherence, prevention of infection and absorption of blood and #exudates, etc. Different types of materials, such as #hydrogel, hydrocolloid, alginate and silicone gel have been used to produce the modern dressings [1,2]. The dyes/colorants obtained from natural sources like plants, animals and minerals are termed as natural dyes [3]. Synthetic dyes are more toxic, non-biodegradable, allergic, and not environmentally friendly as compared to natural dyes [4]. Natural dyes are consumed 10,000 tone's per year which is equal to 1% of the total world synthetic dyes consumption [5,6]. Petrochemical source is the origin of synthetic dyes and some of these dyes contain harmful carcinogenic amines [7]. Germany has banned the production of azo dyes because of their severe harmful effects on living organisms [8]. Natural dyes of some plants not only dye with unique and elegant colours, but can impart antibacterial, deodourising and #ultraviolet protective properties to fabrics [9].
