Embodiment 1

[0022] Add 80g of mineral oil (the kinematic viscosity at 25°C is 10 mm 2 / s), 5g of simethicone oil (kinematic viscosity at 25°C is 10 mm 2 / s) into a 250 mL flask, stirred for 5 min, and then added 13 g of isomeric cetyl alcohol, 1 g of phenyl-modified silicone oil (the kinematic viscosity at 25 °C is 100 mm 2 / s), 1g of isotridecanyl ether phosphate, fully stirred for 40min until the system is transparent and uniform, to obtain spandex oil.

Embodiment 2

[0024] Sequentially add 54g of mineral oil (the kinematic viscosity at 25°C is 10 mm 2 / s), 25g of simethicone oil (kinematic viscosity at 25°C is 10 mm 2 / s) into a 250 mL flask, stirred for 5 min, and then added 6 g of long-chain alkyl modified silicone oil (kinematic viscosity at 25 °C is 800-1000 mm 2 / s), 13g of isomeric stearyl alcohol, 2g of potassium lauryl phosphate, and fully stirred for 40min until the system was transparent and uniform to obtain spandex oil.

Embodiment 3

[0026] Sequentially add 74g of mineral oil (the kinematic viscosity at 25°C is 10 mm 2 / s), 10g of simethicone oil (the kinematic viscosity at 25°C is 10 mm 2 / s) into a 250 mL flask, stirred for 5 min, and then added 13 g of isomeric stearyl alcohol and 1 g of phenyl-modified silicone oil (the kinematic viscosity at 25 °C is 100 mm 2 / s), 1g of isotridecanyl ether phosphate, 1g of polyalphaolefin, fully stirred for 40min until the system is transparent and uniform, to obtain spandex oil.

Abstract

The present invention disclosed a vertical oil agent with high retreating tension, including the following components: 40-90%of mineral oil, 5 to 60%of dievy silicon oil, 1 to 10%of functional modified silicon oil, high carbon heterogeneousFattyol is 3 to 15%, and the sum of the percentage content of the above components is 100%, with a total meter.The oil agent of the present invention is mainly used for dry spinning. The prominent feature is that the fiber has a moderate astringent slippery degree to facilitate its formation, and it has excellent lasting isolation to prevent the inner wire beam from sticking toIt is astringent, astringent but not sticky. "It maintains the astringency between the fiber and the fiber, reducing the friction between the fiber and the metal.It reached the perfect unity of molding and retreating.

Description

technical field [0001] The invention relates to the technical field of spinning oil for dry process, more specifically, relates to a spandex oil with high unwinding tension. technical background [0002] With the ever-changing progress of textile technology, the production process and technology of polyurethane elastic fiber, namely spandex and its products, are constantly updated. With the improvement of spandex production process and the high-efficiency growth of spandex production, new challenges and opportunities have also been proposed for spandex spinning oil, that is, the lubricant used in spandex spinning process. Although the spandex oil agent market has been dominated by Japan's Matsumoto, Takemoto and the American Galston Company for a long time, in recent years, China's spandex oil agent has developed rapidly. Products are also constantly being developed around the market. [0003] In the prior art, the common feature of spandex oil is that it has good lubricit...
