<p> The objective of the present invention is to provide a synthetic fiber treatment agent capable of suppressing fluctuation in yarn manufacturing properties due to seasonal or other temperature variation, and minimizing fluff, yarn breakage, and the like. This synthetic fiber treatment agent is a compound containing an ester component (A) having a structure in which glycerin and a straight-chain fatty acid are ester-bonded, and at least one ester component (B) selected from an ester component (B1) having a structure in which polyglycerin and a fatty acid are ester-bonded, and an ester component (B2) having a structure in which sucrose and a fatty acid are ester-bonded, the straight-chain fatty acid including linoleic acid and a C14-22 straight-chain fatty acid other than linoleic acid, the proportion of the linoleic acid in the entire straight-chain fatty acid being 5-20% by weight, the total weight ratio of the linoleic acid and the C14-22 straight-chain fatty acid other than linoleic acid being 95% by weight or more, and the ester component (B2) having three or more ester groups within the molecule.</p> |
