Main components and functions of spandex oil agent:

(1) Mineral oil and silicon oil: the collocation of mineral oil and silicon oil can adjust the astringency and sliding balance of oil agent, and achieve the unity of forming and unwinding. Tradition of the first generation of agents in mineral oil and some surfactants, and mineral oil gives our agent must be smooth, with most of the surfactant and the compatibility of antistatic agent is better than silicone oil, the price is low, but the oil film strength is low, cake placed after the oil from the bottom of the migration to the surface, cause the bottom of the wire between the stick and unwinding. Compared to white oil, silicone oil or modified silicone oil has more excellent smoothness, and high oil film strength, surface tension is small, not only gives spandex yarn unwinding performance better, and the oil is more even, but with a strong hydrophobic silicone oil itself, and the oil formula of the polar components (such as antistatic agent, stearic acid salt, etc.) compatibility is poor, A certain amount of mineral oil and an appropriate emulsifier must be added to make the oil stable.

(2) surfactant: as the main components of the oil formula mineral oil and silicone oil are hydrophobic substances, in order to give oil antistatic and washable, must be added to the oil agent one or several surfactants. The selected surfactant must be well dissolved in mineral oil, and the antistatic agent must have good compatibility, so that the antistatic agent can be stably dispersed in the oil without sedimentation. At the same time, the selected surfactant can make the oil form a stable emulsion in the water, so that the oil is easy to wash off during the dyeing process.

(3) antistatic agent: spandex is easy to generate static electricity when spinning and forming the high-speed friction with the drum of the winding machine and the high-speed dewinding after application, and spandex silk is hydrophobic fiber, static electricity is not easy to spread, easy to produce wool, broken head and other adverse effects. Therefore, a certain amount of antistatic agent is often added into the spandex oil to improve the antistatic effect of spandex silk.

(4) anti-adhesion additives: at present, most of the spandex oil agents are added stearate as anti-adhesion additives. Stearate as anti-adhesion additives effect is obvious, cheap, but the dispersion process is complex, poor stability, so in some spandex oil agent at the same time also use other additives to replace the anti-adhesion effect of stearate.
