In this paper, preparation technologies for the compound fibers of poly D,L-lactic acid (PDLLA)/hydroxyapatite (HA) were investigated. Starting with PDLLA of weight average molecular mass 94,200-1,130,000 and HA powders of diameter 4-10 μm, the compound fibers of PDLLA/HA were obtained through a two stage process: first the adsorption of HA particles on the surface of PDLLA flakes using the liquid-phase adsorption method then melt-extrusion, and second the spinning collection. Experimental result was showed that the high performance composite fibers of PDLLA/HA with diameter of 15-30 micrometer could be produced by the PDLLA of weight average molecular mass 150,000-300,000, the HA powders content 5 wt%, the melt extrusion temperature below 160°C and the screw rotating speed of 10-15 r/min, the spinning collection speed of 2-5 m/min. |
