| description | The invention relates to porous PBT fiber FDY filaments and a preparation method thereof. Porous PBT fiber FDY filaments are prepared by spinning from modified PBT polyester with a porous spinneret; an arranging mode of spinneret holes on the porous spinneret is in an elliptical arrangement, a center of spinneret holes is positioned on a concentric ellipse, the concentric ellipse comprises a series of ellipses, long axes of all ellipses are collinear, and short axes of all ellipses are collinear. The porous PBT fiber FDY filaments are prepared by metering, extrusion, cooling, oiling, stretching, heat setting, and reeling of modified PBT polyester, and the preparation method of the modified PBT polyester comprises the following steps: a reaction is carried out for terephthalic acid and 1,4-butanediol, in order to obtain 1,4-butylene terephthalate; ester of dihydric alcohol and terephthalic acid obtained by reaction between added terephthalic acid and dihydric alcohol containing branched chains is prepared, and |
