“…301 Chitin filaments were proposed as absorbable surgical sutures even though the halogenated solvents act as plasticizers. 302,303 The trichloroacetic-chloral hydrate-dichloroethane (4:4:2) solvent system was found to dissolve chitin, but the resulting filaments had no substantially improved mechanical properties. 304,305 Moreover, implementation of these spin systems represents a problem: trichloroacetic and dichloroacetic acids are corrosive and degrade chitin even after a short exposure, chlorohydrocarbons are environmentally unacceptable, formic acid can act as a sensitizer, and fluorinated alcohols and ketones are toxic.…”

“…33 The viscosity of the polymer solution can be controlled via the chitin pretreatment (up to 2 h showed added effects), LiCl concentration (optimum 5-9%), chitin concentration (optimum spinnable solution with 5-9% chitin) and temperature. Chitin purified from red crabs was made into fibres by Nakajima et al 34 via dissolution in an amide-LiCl system. Filaments of 5 mm diameter were spun from a spinneret of 0?05 mm diameter, using a butyl alcohol coagulant.…”
