Abstract

The invention relates to the technical field of auxiliary manufacturing in the fiber processing technology, in particular to finish for nylon FDY and a preparation method. The finish for nylon FDY comprises the following components: 55-60% of isooctyl stearate, 5-7% of scouring agents, 5-7% of oleic acid, 8-10% of coconut oil diethanolamine, 5-7% of hydrogenated castor oil polyoxyethylene ether, 5-7% of fatty alcohol polyoxyethylene ether 4, 1-2% of oleic acid sarcosine, 0.5-1% of hypophosphorous acid, 1-1.5% of potassium hydroxide and 5-7% of wetting agent. The preparation method comprises the process steps of mixing, stirring and testing. The finish for nylon FDY has good thermal stability, is less in volatilization and free of coking and has low coefficient of dynamic friction in the drawing stage and good cohesion.

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 preparation method. 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 a...
