Abstract
The invention discloses a process for preparing health seacell fiber spinning. The process comprises the processes of dissolving, stirring, defoaming, drafting and performing ion exchange. The process is characterized by comprising the following steps: dissolving sodium alga acid of a certain viscosity in an aqueous solution containing sodium hydroxide and sodium hypochlorite, keeping a certain temperature for stirring, filtering and defoaming; extruding the sodium alga acid solution into a coagulating bath through a spinning screw, performing ion exchange on the preliminarily formed seacell fibers, and drafting to obtain the seacell fibers with a spinning property.
Description
Technical field
The present invention relates to a kind of preparation technology of the alginate fibre spinning that keeps healthy.
Background technology
Marine resources are abundant, and area is wide, take up an area 71% of sphere area, are the material bases of human survival and development.Marine resources are of a great variety, and reserves are very abundant.Marine natural compound sodium alginate, shitosan, sweet mellow wine etc. are paid close attention to widely, are green renewable resources, especially utilize the alginate fibre of the preparations such as sodium alginate to can be used as green fiber materials'use.The goods of alginate fibre have good health care and medical function, can promote wound to produce sodium alginate, calcium alginate gel by calcium ion and body's sodium ion-exchange, this gel is hydrophilic, can anti-bacteria pass through, thereby promote neoblastic growth, healing of wound.
Summary of the invention
Object of the present invention is low for overcoming alginate fibre spinning concentration, and spinning ability is low, and the shortcoming that intensity is not high provides a kind of preparation technology of the alginate fibre spinning that keeps healthy.Can prepare fast alginate fibre by this technique, and the intensity of fiber obtains certain raising.
For achieving the above object, preparation technology of the present invention comprises: dissolving, stirring, deaeration, drawing-off, ion exchange process, specifically the sodium alginate of certain viscosity being dissolved in containing obtaining mass percent in the water of 0.5～8% NaOH is 5～25% sodium alginate soln.The viscosity of sodium alginate soln is 600～2000mPa.S, and solution temperature is 40-90 ℃; Add again 0.01～0.1% hypochlorous acid or hypochlorite, keep uniform temperature to stir, filter deaeration with 150-250 order filter cloth; The sodium alginate soln preparing is expressed in the first coagulating bath by spinning screw, drawing-off-40-200%, wherein the first coagulating bath is made up of water, lower alcohol, wherein the ratio of water and lower alcohol is 20:80～80:20, wherein lower alcohol is methyl alcohol, ethanol or mixture, and coagulation bath temperature is 5～60 ℃; Again the alginate fibre of first one-step forming is entered to the second gelation and carry out ion-exchange, draw forming, the second gelation is made up of lower alcohol, hydrogen chloride and calcium chloride water, wherein alcohol content 1～8%, hydrogen chloride content 1～6%, calcium chloride content 1～8%, coagulation bath temperature is 30～90 ℃.Alginate fibre is in the second gelation drawing-off, and drafting multiple is 10～300%.The present invention has improved the spinning speed of alginate fibre by gel spinning technique, improved the intensity of fiber simultaneously.
