るため、改良が求められていた。A common method for adding fine particles to polyester is to add the fine particles as a glycol slurry during the polyester manufacturing process, but when aluminum oxide particles are used as the fine particles, the particles have poor dispersibility in glycol. In addition, if the glycol slurry is stored at room temperature for a long period of time, coarse acicular particles will precipitate in the slurry, causing clogging in the filtration equipment during the polyester manufacturing process, and causing damage to the processed product on the base material. Improvements were required as the quality deteriorated.

ましくない。The glycol slurry of the present invention is a glycol slurry containing the above aluminum oxide particles, and contains water in an amount (weight ratio) of 0.03 to 0.2 times the dry weight of the particles. Normally, it is common knowledge among those skilled in the art to use a slurry for adding polyester that has had water removed from it in order to prevent polyester hydrolysis and bumping in the polyester polymerization reaction system as much as possible. However, the slurry of the present invention Surprisingly, it does not have any adverse effects when added to polyester, does not generate the coarse acicular particles, and can improve the dispersibility of aluminum oxide in glycol or polyester. It is. If the amount of water in the slurry is less than 0.03 times the amount (weight ratio) of dry aluminum oxide particles, these improvement effects cannot be expected, and if the amount of water in the slurry exceeds 0.2 times the amount of dry aluminum oxide particles. If this is the case, the temperature increase rate may decrease or bumping may occur during the polyester manufacturing process, degrading the quality of the polyester, which is not preferable.
