Problems solved by technology

At present, the current situation of the use of spandex oils is that spandex with different specifications and chemical compositions needs to use different spandex oils, resulting in many types of spandex oils and difficult management, which virtually increases the production cost of the enterprise.
The existing technology has made breakthroughs in the lubricity, formability and unwinding of spandex oils, but the realization of these effects is based on the use of specific spandex oils for one specification of spandex, that is, the existence of existing spandex oils. Defects of narrow application range of spandex varieties

Embodiment 1

[0016] A spandex oil agent with universal applicability, which is configured to put 60 g of mineral oil, 10 g of dimethyl silicone oil, and 20 g of block polyether silicone oil with a molecular weight of 500 to 800 and a carbon number of 12 to 20 into a reaction vessel, Stir and heat up to 100°C, then add 2g sodium polyoxyethylene ether sulfonate, 1g fatty alcohol polyoxyethylene ether and 7g nano-silicone oil: block polyether silicone oil, stir well for 1 hour until the liquid is transparent and uniform, cool down to room temperature, That is to get spandex oil.

[0017]

Embodiment 2

[0019] A spandex oil agent with universal applicability, which is configured to put 50 g of mineral oil, 10 g of dimethyl silicone oil, and 30 g of block polyether silicone oil with a molecular weight of 1000 to 2000 and a carbon number of 12 to 20 into a reaction vessel, Stir and heat up to 100°C, then sequentially add 1g isotridecyl ether phosphate, 3g fatty alcohol polyoxyethylene ether and 6g nano-silicone oil: block polyether silicone oil, stir well for 1 hour until the liquid is transparent and uniform, cool down to room temperature, That is to get spandex oil.

[0020]

Embodiment 3

[0022] A spandex oil agent with universal applicability, which is configured to put 65g of mineral oil, 15g of dimethyl silicone oil, and 10g of block polyether silicone oil with a molecular weight of about 3000 and a carbon number of 12 to 20 into a reaction vessel, and stir And raise the temperature to 100°C, then add 1g of linear sodium dodecylbenzenesulfonate, 1g of oleyl alcohol polyoxyethylene ether and 8g of nano-silicone oil: block polyether silicone oil, stir well for 1 hour until the liquid is transparent and uniform, and cool down to At room temperature, the spandex oil is obtained.

[0023] The oil agent prepared by the above method was used for dry spinning to prepare spandex yarn, the oiling rate was 5%, the roller method was used for oiling, and the package was wound at 600m / min to obtain 40D spandex yarn. The unwinding tensions of the surface, middle and inner layers of the fresh yarn and the aged yarn aged at 60°C for 12 hours were compared, and the data are s...

Abstract

The invention relates to a polyurethane oil preparation with general applicability. The oil preparation comprises the following components in percentage by weight: 50-67% of mineral oil, 10-20% of dimethicone, 20-40% of modified silicon oil, 1-3% of an antistatic agent, 1-5% of a dispersing agent and 1-10% of a spreading agent, wherein the modified silicon oil is high-carbon alkyl silicon oil of which the carbon number is 12-20 and the molecular weight is 500-3000, wherein the spreading agent is nanometer silicon oil, and the kinematic viscosity of the polyurethane oil preparation at the temperature of 40 DEG C is 7-20 mm2 / s. The spreading agent is added into the oil preparation and is directly acted on the surfaces of polyurethane silks, a uniform spreading effect can be achieved while oiling, the usage effect of the oil preparation is improved, the oil preparation has better applicability for the polyurethane silks with different specifications, and the silks are smooth and astringent but not sticky; at the same time, the spreading agent form a protective isolating layer on the surfaces of the silks, the oil preparation is prevented from being permeated into the inner parts of the silks, and the possibility of breakage and adhesion of the silks in the process of silk returning is reduced.

Description

technical field [0001] The invention relates to a dry-process spandex spinning oil, in particular to a spandex oil with universal applicability. Background technique [0002] Spandex, also known as multi-block polyurethane fiber, is a kind of elastic fiber with strong elasticity. It can stretch up to 500% and can return to its original shape. It is stronger than rubber and more wear-resistant. It is widely used in the clothing industry. multiple fields. As the domestic production of spandex and its products continues to grow, higher requirements are placed on the production and processing technology of spandex. At present, the production of spandex mainly adopts dry spinning, and the spandex oil used in the dry spinning process has an important impact on the quality of spandex products. At present, the current situation of the use of spandex oil is that spandex with different specifications and chemical compositions needs to use different spandex oils, resulting in many ty...
