| Abstract: | Sodium alginate and hydroxyapatite were used for preparation of composite fiber,in which the effects of the concentration of sodium alginate and first coagulation bath,temperature of first coagulation bath,draw ratio of spinneret and the composition of second coagulation bath on the breaking strength and adsorption amount were studied using orthogonal and single factor analysis method.Considering the breaking strength and adsorption amount comprehensively,the optimum process was set up as follow: sodium alginate of 3%,CaCl2 solution of 5% and coagulation temperature of 15 ℃ in the first coagulation bath,minus spinneret draw ratio,water as the second coagulant,was determined. |
