Embodiment 1

[0030] Example 1: According to the formula, HP-136 (5,7-di-tert-butyl-3-(3,4-dimethylphenyl)-3H-benzofuran-2-one), bis(2,4- Di-tert-butylphenyl) pentaerythritol diphosphite and Tween 20 are mixed, and after standing for 20 minutes, add unmodified bis (2,4-dicumylphenyl) pentaerythritol diphosphite and sulfur Dilauryl dipropionate is replaced, and the anti-yellowing agent of embodiment 1 is obtained after mixing.

[0031] Add the anti-yellowing agent of Example 1 to the white nylon raw material of the underwear for high temperature setting.

Embodiment 2

[0033] Bis(2,4-dicumylphenyl)pentaerythritol diphosphite, dilauryl thiodipropionate, HP-136 (5,7-di-tert-butyl-3-(3,4- Dimethylphenyl)-3H-benzofuran-2 ketone), two (2,4-di-tert-butylphenyl) pentaerythritol diphosphite and Tween 20 are mixed, obtain embodiment 2 after mixing uniformly Anti-yellowing agent.

[0034] Add the anti-yellowing agent of Example 2 to the white nylon raw material of the underwear to carry out high temperature setting.

Embodiment 3

[0036] According to the recipe, HP-136 (5,7-di-tert-butyl-3-(3,4-dimethylphenyl)-3H-benzofuran-2-one), bis(2,4-di-tert-butyl Phenyl) pentaerythritol diphosphite and Tween 20 are mixed, after standing for 20 minutes, add modified bis(2,4-dicumylphenyl) pentaerythritol diphosphite and thiodipropionate diphosphite Lauryl ester, after mixing homogeneously, obtains the anti-yellowing agent of embodiment 3.

Abstract

The invention provides an environment-friendly high-temperature yellow agent which comprises 10-30% of di(2,4-dihydrophenyl) pentaerythritol diphosphite, 20-30% of HP-136(5,7-di-tert-butyl-3-(3,4-dimethyl phenyl)-3H-benzofuran-2 one), 40-50% of di(2,4-di-tert-butyl) pentaerythritol diphosphite, 10-20% of dilauryl thiodipropionate and 2-8% of Tween 20, wherein the di(2,4-dihydrophenyl) pentaerythritol diphosphite and the dilauryl thiodipropionate are both subjected to modification treatment process. The environment-friendly high-temperature yellow agent provided by the invention is free of APEO(alkylphenol ethoxylate), free of ADH (alcohol dehydrogenase), small in use amount and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of textile material treatment, and in particular relates to the application of an environment-friendly high-temperature anti-yellowing agent in the finishing of textile fabrics. Background technique [0002] In recent years, as women's intimate underwear, in addition to being breathable and comfortable, it must also have shape retention and firmness, soft and smooth hand feeling, especially supporting force, good adhesion and close-fitting comfort. At present, the thick sponge in the underwear on the market makes it not so light to wear, and it has poor wash fastness and is easy to deform. In order to better meet women's requirements for more comfortable and lightweight underwear, the development of integrated seamless underwear fabrics has become a current research hotspot. [0003] The one-piece seamless underwear is extremely close-fitting and comfortable, just like human skin, it is natural and comforta...
