Description

technical field [0001] The invention belongs to the field of spinning oil, and relates to an oil and a preparation method thereof. Background technique [0002] Due to the small dielectric constant, low moisture regain and high friction coefficient of most chemical fibers, spinning oil must be used in the spinning process. The main component of the oil agent is a surfactant, which can form a directional adsorption layer on the surface of the chemical fiber, that is, an oil film. On the one hand, the hydrophilic group of the oil film faces the space, which will absorb the moisture in the air, and form a continuous water film on the surface of the fiber, so that the charged ions can migrate on it, reducing the accumulation of static charge caused by friction , so as to reduce the surface resistance of the fiber and increase the conductivity; on the other hand, the oil film isolation fiber can have a certain affinity for the fiber, so that it has a certain degree of clustering...
