Embodiment 1

[0034] After the monkey is neutralized, the process of adding the yellowing and brightening agent:

[0035] 1. Spray 10% potassium permanganate solution evenly on the surface of denim clothing.

[0036] 2. Put the sprayed monkey clothes into a washing machine with 100L of tap water, add 300g of sodium metabisulfite, and neutralize at 40°C for 5 minutes.

[0037] 3. Put the neutralized trousers into a washing machine with 100L of tap water, add 50g of yellowing and brightening agent, and treat at room temperature for 10 minutes.

[0038] 4. Wash 2 times.

[0039] 5. Dehydration.

[0040] 6. Dry at 100°C for 20 minutes.

[0041] The deyellowing and brightening agent used in the present embodiment is obtained by the following method: by weight parts, horse-propylene copolymer 35, sodium percarbonate 53, and nonionic surfactant 12 are sequentially dropped into DSN type cantilever asymmetric double-helix conical mixing In the machine, control the speed at 10-30r / min, stir for 5...

Embodiment 2

[0052] 1. Put the jeans into a washing machine with 100L of tap water, add 1L of 10% bleach, and bleach at 40°C for 10 minutes.

[0053] 2. Put the bleached trousers into a washing machine with 100L of tap water, add 300g of soda, and neutralize at 40°C for 5 minutes.

[0054] 3. Put the neutralized trousers into a washing machine with 100L of tap water, add 100g of yellowing and brightening agent, and treat at room temperature for 10 minutes.

[0055] 4. Wash 2 times.

[0056] 5. Dehydration.

[0057] 6. Dry at 100°C for 20 minutes.

Embodiment 3

[0064] The anti-yellowing and brightening agent applied to denim clothing is obtained by the following method: 20 parts by weight of horse-propylene copolymer, 60 sodium percarbonate and 10 non-ionic surfactants are sequentially dropped into DSN type cantilever asymmetric double-helix cone In the mixer, control the rotation speed at 10r / min and stir for 20 minutes to prepare.

[0065] The process of applying the above-mentioned deyellowing and brightening agent to process denim garments:

[0066] 1. Monkey spraying process:

[0067] step:

[0068] Equipment: industrial washing machine

[0069] Spray monkeys: evenly spray potassium permanganate solution with a concentration of 5% on the surface of denim clothing

[0070] Debleaching: tap water 100L, denim garments sprayed with high manganese, sodium metabisulfite 1.0g / L, 40°C for 5 minutes, speed 30 rpm.

[0071] Yellowing and brightening: tap water 100L, neutralized denim clothing, yellowing and brightening agent 0.5g / L, t...

Abstract

The invention relates to a de-yellowing brightening agent applied to jeans garment, and a preparation method and an application thereof. 20-50 parts by weight of a maleic-methyl acrylate copolymer, 30-60 parts of sodium percarbonate and 10-15 parts of a nonionic surfactant are put into a DSN type cantilever unsymmetrical double-spiral conical mixer sequentially, the rotating speed is controlled at10-30 r / min, stirring is performed for 5-20 minutes, and thus the de-yellowing brightening agent applied to jeans garment can be prepared. Compared with the prior art, the prepared de-yellowing brightening agent can effectively solve the problem of yellow discolouration of a monkey position and water bleaching parts, and treated cloth cover can be more white, clearer and brighter.

Description

technical field [0001] The invention relates to a finishing agent for clothes, in particular to a yellowing and brightening agent applied to jeans, a preparation method and application thereof. Background technique [0002] Denim has experienced hundreds of years of experience from tooling to fashion. Over the past century, denim has never left the fashion stage. It can be the most economical life clothing or the most personalized fashion. It responds to ever-changing fashion with a calm face. . The effect created by the washing process has become a classic of denim clothing. In recent years, the value and beauty of the whole denim has been more and more reflected in the washing process, among which hand rubbing, whiskering, monkey spraying, and bleaching are the most popular washing processes. The so-called monkey spraying is to use a spray gun to spray different concentrations of permanganate on the denim garment according to the design requirements, and use the oxidatio...
