Abstract: PURPOSE:To produce a particle-contg. polyester contg. no agglomerated coarse particle by continuously feeding a glycol slurry of fine inert inorg. particles to a high-shear dispersing machine of a specific structure, dispersing the particles homogeneously, and then feeding the slurry to a polyester producing step. CONSTITUTION:A glycol slurry of inert inorg. particles (e.g. silica) having a mean primary particle diameter of 3mum or lower is continuously fed to a high- shear dispersing machine which meets the following three requirements: the inside of the machine is a cylindrical space, which is filled with dispersion- promoting particles 4 (e.g. glass particles) having a mean diameter of 0.8-2mm and occupying 60-90vol.% of the space; when looked from above, the machine is equipped with a plurality of stirring blades 3 having pins radially extending form the center to at least four directions; and the distance between the inner wall of the machine and a point of the pin is at most three times the means diameter of the dispersion-promoting particles. The inert inorg. particles are homogeneously dispersed in the glycol, and then the slurry is fed to a polyester producing step wherein a dicarboxylic acid component and a glycol component are reacted, producing a particle-contg. polyester.

Abstract: PURPOSE:To feed an additive automatically and exactly, by holding an additive container containing an additive with an additive feed robot, carrying the container to an additive adjusting tank by a traveling unit and feeding the additive to the adjusting tank by turning over the container. CONSTITUTION:An additive container 4 containing an additive is held and lifted up by the chucking hand 6 of an additive feed robot and is covered with a lid 9. The additive feed robot 5 is carried to the position of an additive adjusting tank by a traveling unit 20. The additive container 4 is turned 180 deg. by a hand turning mechanism 7 while it is held with the chucking hand 6, the lid 9 of the additive container 4 is opened to feed the additive in the additive container 4 to the additive adjusting tank. The whole of the additive is fed surely without leaving any in the container by vibrating the additive container 4 by actuating a vibrator 14 during feeding of the additive.
