摘要:
The present invention relates to a chemically modified cellulose/alginate co-spun (seacell) fibres, wound dressing made therefrom and preparation method thereof. The seacell fibres are subject to a chemical modification through which a hydrophilic carboxymethyl group is introduced into the cellulose structure making the chemically modified seacell fibres more absorbent. The modified cellulose has a degree of substitution of 0.05-0.5 the seacell fibres have a linear density of 0.5-5 dtex and a fibre length of 5-180 mm. The present invention enables seacell fibres to have hygroscopic and gel-forming properties, while retaining its active ingredient of algae particles. The dressing made from this material can provide a combined benefit of CMC and alginate to the chronic wounds, enhancing the benefits of the moist wound healing environment.
