AI Technical Summary

Problems solved by technology

But the disadvantage is: poor removability of the oil agent, which makes it difficult to clean after spinning, and affects the subsequent dyeing, compounding, laminating and other processes
Spandex yarn is not easy to dye. Although the dyeability of spandex yarn is improved by using additives, it is still poor compared with other fibers, and the color fastness is also poor.
The spandex yarn produced with silicone oil agent, because the silicone oil is not easy to remove, directly affects the coloring rate of the spandex yarn; for example, in recent years, the application of spandex yarn in diapers is also growing rapidly, and the market potential is great. Spandex yarns used in diapers require a high degree of bonding and compounding, but the spandex yarns currently produced with silicone oil agents have obvious deficiencies in the degree of bonding and compounding

Embodiment 1

[0042] The formula components are as follows in the present embodiment:

[0043]

[0044] ①Add magnesium stearate and wetting agent lauryl alcohol polyoxyethylene ether first, disperse on a high-speed disperser for 20 minutes, then gradually add isosteric alcohol and isomeric eicosic acid, then add dispersant polycarboxylate ammonium salt, heat up After reaching 120°C, stir for 30 minutes, then lower the temperature to 80°C to obtain substance A;

[0045]②Raise the temperature of isooctyl stearate to 60°C, then add substance A, mix and cool down to 40°C, then add antistatic agent isotridecyl alcohol polyoxyethyl ether and C8-10 alcohol polyoxyethyl ether, add antioxidant Agent, mix evenly, that is.

[0046] In this example, a silicone-free spandex dry-spinning oil product was obtained as a nearly transparent liquid with a viscosity of 14.0 mPa.s at 25°C.

Embodiment 2

[0048] The formula components are as follows in the present embodiment:

[0049]

[0050] ① First add calcium stearate and wetting agent C10-12 fatty acid polyoxyethylene ester, disperse on a high-speed disperser for 20 minutes, then gradually add isomeric cetyl alcohol and isomeric eicosic acid, then add polycarboxylate sodium salt, heat up After reaching 120°C, stir for 40 minutes, then lower the temperature to 70°C to obtain substance A;

[0051] ②Raise the temperature of isotridecanyl stearate to 60°C, then add substance A, mix and cool down to 40°C, then add antistatic agent and nano silicon dioxide, and mix well to get ready.

[0052] In this example, a silicone-free spandex dry spinning oil product was prepared. The product was a clear and transparent liquid with a viscosity of 13.0 mpa.s at 25° C.

Embodiment 3

[0054] The formula components are as follows in the present embodiment:

[0055]

[0056]

[0057] ① First add zinc stearate and wetting agent polyoxypropylene lauryl ether, disperse on a high-speed disperser for 20 minutes, then gradually add isomeric cetyl alcohol and isomeric tetracosanoic acid, and then add dispersant lauryl polyethylene glycol Glycol ether sodium sulfate, heat up to 120°C, stir for 30 minutes, then cool down to 70°C to obtain substance A;

[0058] ②Raise the temperature of isocetyl stearate to 60°C, then add substance A, mix and cool down to 40°C, then add antistatic agent isotridecyl alcohol polyoxyethylene ether and C10-12 alcohol polyoxyethylene ether Phosphate ester, defoamer, after mixing evenly.

[0059] In this example, a silicone-free spandex dry spinning oil product was prepared, which was a nearly transparent liquid with a viscosity of 13.5 mpa.s at 25°C.

Abstract

The invention relates to a spandex dry spinning oil agent not containing organosilicone and a preparation method thereof. The spandex dry spinning oil agent comprises 60 to 90% of ester type compound, 0.1 to 3% of higher fatty acid salt, 0.5 to 2.5% of wetting agent, 1 to 5% of dispersant, 1 to 10% of dissolving additive, and 0.5 to 20% of anti-static agent. The spandex dry spinning oil agent has the advantages that (1) the oil agent adhered onto fiber can be easily removed, and the oil-applied spandex yarn can be laminated, compounded and adhered, and be easily and uniformly dyed; (2) by adopting the formula compounding and technology optimizing, the dispersion of metal magnesium is small, and the nanometer level can be reached; the spandex fiber has good anti-adhering and isolation properties, the anti-adhering and adhering-preventing effects are good, and the unwinding property of inner layer and outer layer is excellent; the smoothness is proper.

Description

technical field [0001] The invention belongs to the technical field of dry spinning oil, and more specifically relates to a silicone-free spandex dry spinning oil composition, and also relates to a preparation method of the composition. [0002] technical background [0003] Spandex is an indispensable textile raw material for the modern textile and garment industry. It can be used in all fabrics that require good elastic recovery. Therefore, it is widely used in various underwear, sportswear, fitness clothes, swimwear, high elastic socks, tights, Do not wet such areas. Spandex spinning methods include dry spinning, melt spinning, wet spinning and other methods. Dry spinning technology is the most widely used method in the current spandex industrial production, accounting for more than 80% of the world's total spandex production. [0004] Compared with the rapid growth of domestic spandex production, spandex spinning oil, as a lubricant in the spinning process of spandex, h...
