Chitosan fibres from

Organic removal processes are achieved by adsorption, foam seperation and chemical oxidation. In adsorption activated carbon, silica gel, chitosan fibre, fullers earth etc. are used to absorb impurities from waste water. The sizes from the... [Pg.385]

Fibrous fillers for biomedical PLA-based FRPs include carbon and inorganic fibres [406], PLLA (i.e. self-reinforcement) [407,408], poly(p-dioxane) fibre [409], chitin [410], biodegradable fibre (e.g. bioactive glass, chitosan fibre, polyester amides) [411], hydroxyapatite fibre [412], hydroxyapatite whiskers [413], halloysite (Al2Si205(0H)4) nanotubes [414] and the fibre from different tissue types of Picea sitchensis [415],... [Pg.212]

The nonwoven fabric made from chitin fibres and atelocollagen filaments can be used as an artificial skin for treating bum wounds (Anandjiwala, 2006 Yoshito, 1989). A nonwoven fabric of regenerated collagen has been commercialized for wound covering. Chitosan fibres are of particular interest due to their large surface... [Pg.233]

To enhance the biomedical capabilities of chitosan, alginate, another natural polysaccharide extracted from brown sea weed, which has been used as wound dressing for a number of years, has recently been successfully combined with chitosan to generate hybrid fibres with superior properties of high liquid absorption, antimicrobial, anticoagulant and wound healing. Research at University of Bolton has developed this concept and acquired the universal patent for its imminent commercial exploitation (Miraftab et al., 2008 Miraftab et al., 2011, p345)... [Pg.179]

Crab shell fibre - Chitosan or Chitin as it is also known, is an amazing fibre made from discarded crab shells. This is most often made into medical bandages. This fibre helps the healing process and helps avoid the formation of scar tissue. [Pg.40]

Chitosan has already been used as a support in several catalytic applications, including some which exploit its chirality 15-19), Finally, and a major benefit, is the ability of chitosan to form films and fibres readily, 13) allowing the coating of reactor walls and the forming of catalyst systems with controlled architecture, e.g. films, membranes, porous beads. Such behaviour relies on the ability of chitosan to dissolve in dilute aqueous acid (via protonation of the amino function) to give solutions from which films can be cast. Chitosan is completely insoluble in virtually all other solvent systems. [Pg.172]

Chitin (poly-A-acetyl-D-glucosamine, 2-acetamido-2-deoxy-1,4-P-D-glucan) is one of the three most abundant polysaccharides (along with starch and cellulose) and is extracted from shells of crustaceans and cell walls of fungi. Chitosan is produced by deacetylation of chitin and can be spun into fibres, cast into films, or precipitated in a variety of micro-morphologies. Major applications are in biomaterials, pharmaceuticals, cosmetics, metal ion sequestration, agriculture and the food industry. ... [Pg.199]
