摘要

The effects of spinning bath components and calcium chloride concentration on tensile and absorption properties of alginate fibres containing 25% w/w branan ferulate has been reported in an earlier paper, (Miraftab et al., 2000). The study concluded that a 1% w/v concentration of calcium chloride provides the optimum condition for achieving suitably strong fibres with adequate absorption capacity whilst allowing only the minimum of branan ferulate loss during wash and post production treatments. In this paper the effects of introducing a third component, sodium carboxymethyl cellulose (NaCMC, Blanose~®7HF), on overall tensile and absorbency of these new fibres (ABC) are reported. In a comparison of their absorbency with that of commercially available fibres of similar calibre, it was shown that 10% w/w NaCMC inclusion improves fibre wet strength and thus structural integrity of potential wound dressings. Furthermore, the new fibres show a significant increase in both saline and Solution A uptake compared to the commercial fibres. Analytical investigations have shown that Aquacel~® wound dressing fibres (made by ConvaTec) contain a CMC type material which is essentially identical in terms of chemical functionality to Blanose~® 7HF sodium carboxymethyl cellulose (made by Hercules Aqualon). The degree of substitution (in terms of carboxymethylation) in Blanose 7HF used in ABC fibres is shown to be approximately twice that of Aquacel. ABC fibres are therefore offered as a viable alternative to existing materials.
