Chitosan Blended Fabrics with Antibacterial and Biodegradable Performance
Chitosan fiber fabrics have been used for intimate apparel for its excellent antibacterial and antimicrobial properties. However, there is a large variation of the antibacterial and antimicrobial properties of chitosan products due to the unclear antibacterial mechanism of chitosan fiber, i.e. the relationship between the degree of deacetylation and the resultant electrical and antibacterial properties. Besides, there is no suitable blending technology of chitosan fiber with other fibers for yarn and fabric production. This project aims to develop chitosan fiber blended fabrics for functional intimate apparel with excellent antibacterial activity. First, the antibacterial mechanism of chitosan fiber will be investigated and the chitosan fiber will be fully characterized. Secondly, fiber blended trials will be conducted to study the chitosan fiber blending effect with other fibers. Furthermore, functional knitted fabrics will be designed based on the antibacterial mechanism and blending technology and the fabrics will be produced and characterized. This study proposes a cost-effective method to develop functional chitosan fiber blended knitted fabrics based on the established relationship between the degree of deacetylation and the resultant electrical and antibacterial properties and newly developed chitosan fiber blending technology. This technology will greatly promote the development of high value-added and functional textiles.
