Embodiment 1

[0022] Add 80g of mineral oil (the kinematic viscosity at 25°C is 10mm 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 invention discloses a high-unwinding-tension spandex oil preparation, which comprises the following components: 40-90% of mineral oil, 5-60% of dimethyl silicone oil, 1-10% of functional modified silicone oil and 3-15% of high-carbon isomerized fatty alcohol, and the sum of content percentages is 100% by total weight. The oil preparation disclosed by the invention is mainly applied to dry spinning, and has an outstanding characteristic that fibers both have a moderate astringent sliding degree so as to facilitate the forming of the fibers, and have an extremely good lasting barrier property so as to prevent inner-layer yarn bundles from being adhered, namely, the fibers are slidable but astringent, and astringent but non-stick, so that the astringent sliding degrees between fibers are kept, and the friction among fibers and metals is reduced, therefore, good astringent sliding property, permeability, antistatic property and unwinding property can be given to fibers, and then the perfect unification of forming and unwinding is achieved.

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...
