Abstract

This method for managing a production line is provided with: a step of preparing a lubricating oil composition which comprises, based on the total amount of the lubricating oil composition, 50 mass% or more of a base oil in which the aniline point and kinematic viscosity at 40°C satisfy the condition represented by formula (1): 0.4×(aniline point)-15×log(kinematic viscosity at 40°C)≥20 (1) and which does not emit visible light when irradiated with ultraviolet light by a black light; and in a production line in which a lubricating oil is used, a step of using the lubricating oil composition and monitoring contamination, fouling or degradation of a product due to substances that are luminescent under ultraviolet light by irradiating the product with ultraviolet light.

Description

technical field [0001] The present invention relates to a lubricating oil composition and a method for managing a production line, and in particular, to a lubricating oil composition used in a product manufacturing device, such as a spinning machine, a textile machine, or a knitting machine, that hates contamination by chemicals containing lubricating oil, And the management method of the production line using the lubricating oil composition. Background technique [0002] Lubricating oil is used in each part of a production line that manufactures fibers, woven fabrics, knitwear, etc., using spinning machines, weaving machines, or knitting machines. In such a production line, lubricating oil may leak / scatter or the like to contaminate / contaminate products. Therefore, conventionally, a method of adding a fluorescent dye to lubricating oil, irradiating it with ultraviolet rays from a black light to emit visible light, and visualizing contamination for product management has be...
