Abstract
The invention relates to knitting needle lubricating oil. The knitting needle lubricating oil comprises the following components in percentage by weight: 70-80% of base oil consisting of a fatty acid ester mixture; 0.1%-1% of a surfactant; 2%-5% of an anti-wear agent; 1%-5% of a flame retardant; 1%-3% of a tackifier; 0.5%-2% of an antioxidant; 0.1%-0.5% of a preservative; and 0.05%-0.5% of an antibacterial agent. The lubricating oil is particularly suitable for knitting needle lubricating oil operated at high temperature and high speed, and can provide long-acting wear resistance, high temperature resistance, oxidation resistance, flame retardance and antimicrobial characteristics. The lubricating oil aims to reduce friction between a knitting needle and a needle groove, so that equipment abrasion is reduced, and the service life of the knitting needle is prolonged.
