Problems solved by technology

Naturally containing polyphenols, it is easy to cause yellowing in the air or heat processing, and there are many symbiotic by-products of natural polyphenols, which will also cause yellowing. Its washability on fabrics mainly depends on the amount of Phenolic substances contain a large amount of polar phenolic hydroxyl polar bonds combined with the fabric, this binding force is very weak, not firm, and easy to wash off

Embodiment 1

[0027] This embodiment provides a preparation method of a washable and chlorine-resistant enhancer for nylon, nylon / spandex dyed fabrics, comprising the following steps:

[0028] S1), each component of the present embodiment is as follows:

[0029]

[0030] S2), in a dry 1000L three-neck round bottom flask, add 450g of biuret triisocyanate, 395g of butanone and stir for 30 minutes, slowly add 85g of acetone oxime, react at 80°C for 4 hours, cool down to 60°C, add 70g of hydrated Hydrazine (80%) was reacted for 1 hour, and the butanone was removed by decompression and vacuum pumping to obtain the corresponding lifting agent.

Embodiment 2

[0032] S1), each component of the present embodiment is as follows:

[0033]

[0034] S2), in a dry 1000L three-neck round bottom flask, add 500g of biuret triisocyanate, 336g of butanone and stir for 30 minutes, slowly add 78g of acetone oxime, react at 80°C for 4 hours, cool to 60°C, add 86g of hydration Hydrazine (80%) was reacted for 1 hour, and the butanone was removed by decompression and vacuum pumping to obtain the corresponding lifting agent.

Embodiment 3

[0036] S1), each component of the present embodiment is as follows:

[0037]

[0038] S2), in a dry 1000L three-neck round bottom flask, add 550g of biuret triisocyanate, 250g of butanone and stir for 30 minutes, slowly add 129g of acetone oxime, react at 80°C for 4 hours, cool down to 60°C, add 71g of hydration Hydrazine (80%) was reacted for 1 hour, and the butanone was removed by decompression and vacuum pumping to obtain the corresponding lifting agent.

Abstract

The invention provides a washable and chlorine-resistant improver for a nylon and nylon / spandex dyed fabric and a preparation method of the washable and chlorine-resistant improver. The washable and chlorine-resistant improver is obtained by taking biuret triisocyanate, acetoxime and hydrazine hydrate as raw materials and butanone as a solvent, and removing the solvent under reduced pressure aftercomplete reaction. According to the improver, the hand feeling of the fabric is not influenced, reactive groups can be released during high-temperature baking to form a net-shaped structure with thefabric and an auxiliary agent, so that the washability on the fabric is good; the finished dyed fabric is small in color change, and particularly has a good effect of improving the chlorine resistanceof some sensitive colors such as turquoise blue and lake blue, and the chlorine resistance can reach the 4-5 level; the chlorine resistance principle of the washable and chlorine-resistant improver is different from that of similar products in the market, the washable and chlorine-resistant improver has reductive hydrazine groups, the reductive hydrazine groups and available chlorine in bleachingwater can be subjected to oxidation-reduction reaction instead of simple adsorption, and therefore the color of the finished fabric is not dark and still bright and is incomparable to the similar products in the market.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing auxiliaries, in particular to a washing and chlorine resistance enhancer for nylon and nylon / spandex dyed fabrics and a preparation method thereof. Background technique [0002] Nylon and nylon / spandex fabrics are often used as swimming fabrics. A certain amount of chlorine water must be added to the swimming pool to sterilize and disinfect. After a swimsuit is soaked in chlorine-containing swimming pool water for a long time, the color of the fabric will change greatly, especially Especially for some sensitive colors such as emerald blue and bright blue, the color change is greater. The color fastness to chlorine of swimsuits is an important detection index. [0003] The high-end swimsuit fabrics exported to Europe and the United States are required to have a chlorine water fastness of 4-5 or above. After 10 times of washing, the chlorine water fastness should reach 4 or above...
