23 Jul Preparing method of hollow multilayer structure fibers, obtained fibers and application of fibers
Abstract
The invention discloses a preparing method of hollow multilayer structure fibers, the obtained fibers and application of the fibers. A wet spinning method is utilized for preparing a low-molecular-weight polysaccharide polyelectrolyte into a spinning solution, a high-molecular-weight polysaccharide polyelectrolyte is added into a coagulating groove to serve as a coagulating bath, the spinning solution is injected into the coagulating bath through an injector, a diffusion reaction is carried out, and winding, washing, drying are conducted to obtain the fibers. The preparing method is simple inequipment, low in cost, high in spinnability, and suitable for scale production; meanwhile, the prepared hollow multilayer fibers have controllability in the number of layers, the number of cavities and the diameter, good tensile strength and an ultrahigh specific surface area, and are widely applied in the fields of catalysis, adsorption, filtering, tissue engineering and the like.
