Abstract

The invention relates to the technical field of auxiliary agent preparation in a fiber processing technology, in particular to nylon full drawn yarn (FDY) oiling agent and application. The nylon FDY oil comprises the following components: 55-60 percent of stearic acid isooctyl ester, 5-7 percent of scouring agent, 5-7 percent of oleic acid, 8-10 percent of coconut oil diethanol amine, 5-7 percentof hydrogenated castor oil polyoxyethylene ether, 5-7 percent of fatty alcohol polyoxyethylene ether, 1-2 percent of oleic acid creatine, 0.5-1 percent of hypophosphorous acid, 1-1.5 percent of potassium hydroxide and 5-7 percent of wetting agent. The nylon FDY oil is added into deionized water and stirred into 8-15 percent of emulsion, the emulsion is added into a cured sliver, and the oiling rate is 0.8-1.5 percent. The invention provides the nylon FDY oiling agent, which has the advantages of high heat stability, less volatilization, no coking, low kinetic friction coefficient in a drawingphase and favorable cohesive force, and application.

Description

technical field [0001] The invention relates to the technical field of auxiliary agent manufacturing in fiber processing technology, in particular to nylon FDY oil agent and its application. Background technique [0002] As an indispensable chemical auxiliary in the production and processing of synthetic fibers - spinning oil, the current spinning speed of nylon FDY high-speed one-step spinning has reached more than 4500 m / min. Under such high-speed operation, high shear force, The effect of high friction will inevitably increase the damage to the polymer, thereby generating heat and forming coke. At present, the thermal stability and dynamic friction coefficient of domestic high-speed spinning oils cannot meet the requirements of high-speed spinning. Contents of the invention [0003] The invention provides a nylon FDY oil with good thermal stability, less volatilization, no coking, low dynamic friction coefficient in the stretching stage, and good cohesion, and its appl...
