Chitosans fibres

Cross-linking agents have been proposed for the improvement of chitin fibres in the wet state. Epichlorohydrin is a convenient base-catalysed crosslinker to be used in 0.067 M NaOH (pH 10) at 40 °C. The wet strength of the fibres was considerably improved, whereas cross-hnking had neghgible effect on the dry fibre properties. Of course, the more extended the chemical modification, the more unpredictable the biochemical characteristics and effects in vivo. Every modified chitin or modified chitosan fibre should be studied in terms of biocompatibiUty, biodegradabiUty and overall effects on the wounded tissues. [Pg.186]

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]

KytoCel by Aspen, reported by Aspen (2014), is a highly absorbent dressing composed of natural, biodegradable acylated chitosan fibres, which bond with wound exudate to form a clear gel that locks in fluid, absorbs pathogens, and is conformable to the wound bed. [Pg.76]

Textile materials can be used in moist wound management as fibres themselves (advanced fibres such as alginate and chitosan fibres), or conventional/advanced fibres can be modified or coated with various substances such as honey or hydrogels to obtain special properties such as ultra-absorbency, drag release, etc. In general, textiles used in wound-dressing products come in all possible forms, including fibres, nanofibres, filaments, yarns, and woven/knitted/non-woven and composite materials.

Regenerated chitin derivative fibres were used as binder in a paper-making process. N-iso-butyl chitin fibres were added at 10 % yield to reinforce the breaking strength of paper [97,98]. Chitin fibres and/or chitosan fibres with diameter <100 nm and an aspect ratio >5 were used in pneumatic tires and give a good abrasion resistance [99]. [Pg.71]

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]
