Abstract
PURPOSE: To make it possible to operate the spinning for a long time without the nozzle clogging or yarn breakage and prepare high-tenacity chitinous fibers suitable for absorbable surgical sutures, by wet spinning a chitinous dope at a specific spinning draft.
CONSTITUTION: Chitin is dissolved in a solvent, preferably a mixed solvent of trichloroacetic acid with methylene chloride, etc. at a weight ratio of (25W75): (75W25) in a concentration of preferably 1W10wt% to prepare a chitinous dope, which is then wet spun into a coagulating bath, e.g. acetone, at a spinning draft of 0.4W1.4, preferably 0.6W1.1, to afford the aimed fibers having a dry strength ≥2g/denier.
