    • PURPOSE: A biodegradable hollow fiber and a manufacturing method thereof are provided to give biodegradable polyester hollow fiber with possible spinning and improved elongation property. CONSTITUTION: A biodegradation hollow fiber having heat insulation property is a fiber manufactured by esterification and polycondensation of a mixture consisting of acid components of aliphatic acids having carboxylic acid group and aromatic acids having phenylene group, sulfonic acid metal salt, and diol components of carbon number of 2-14. A biodegradable hollow fiber manufacturing method comprises a mixing step in which aliphatic acid of 9 to 20 mole %, aromatic acid of 79 - 90 mole %, and sulfonic acid metal salt of 0.1 to 1.5 mole % are mixed together and materials including acidic components (aliphatic acid and aromatic acid) and sulfonic acid metal salt are mixed with diol components in 1.0 : 1.0-1.4 weight ratio; an esterification step which manufactures oligomer by stirring for 210 to 330 minutes at 200 to 260°C and at a speed of 40 to 80 rpm; a polyester resin manufacturing step which manufactures polyester by polycondensing above mentioned oligomer for 180 - 210 minute at 240 - 285°C and at a speed of 40 - 100rpm; and a hollow fiber manufacturing step which manufactures hollow fiber of a hollow ratio of 10-30% by spinning polyester resin.
