Embodiment 1

[0021] Preparation of Small Molecule Water

[0022] Take natural fresh water, sterilize and filter, distill and purify, then heat and boil in 80-450Hz, 200-850V pulsed oscillating electric field, and then cool and fill under the condition of 0.2-0.7 atmospheric pressure, that is, the water after filling and sealing The temperature is 18-20°C.

[0023] The cohesion of the above-mentioned small molecular water increases, the surface tension increases, the pH thereof is between 7.3 and 8.2, and the half-width of the water molecular cluster is between 35 and 42 Hz.

Embodiment 2

[0025] A kind of dyeing auxiliary agent, comprises following component according to parts by weight (g):

[0026] 2 parts of chitosan, 1.5 parts of sodium polyacrylate, 4 parts of color fixing agent NFC, 6 parts of leveling agent SE, 3 parts of alkylphenol polyoxyethylene ether, 3 parts of sodium alkyl sulfosuccinate, polyether modified silicone oil 8 parts, 3 parts of polyvinyl alcohol, 1.5 parts of cross-linking agent MH and appropriate amount of small molecule water.

Embodiment 3

[0028] A kind of dyeing auxiliary agent, according to parts by weight (g) comprises following component:

[0029] 3 parts of chitosan, 5 parts of chlorogenic acid, 2.5 parts of sodium polyacrylate, 3.5 parts of color fixing agent NFC, 10 parts of leveling agent SE, 2.5 parts of alkylphenol polyoxyethylene ether, sodium alkyl sulfosuccinate 5 parts, 13 parts of polyether modified silicone oil, 1.8 parts of polyvinyl alcohol, 2.5 parts of crosslinking agent MH and appropriate amount of small molecule water.

[0030] Its preparation method comprises the following steps:

[0031] (1) Weigh chitosan, chlorogenic acid, and polyether modified silicone oil sequentially according to parts by weight, then mix the above three raw materials and add an appropriate amount of small molecule water, stir ultrasonically for 45 minutes, and then mix them under the condition of 1500 rpm Stir for 8h to obtain a suspension;

[0032] (2) Add sodium polyacrylate, color fixing agent NFC, and levelin...

Abstract

The invention relates to the technical field of dyeing of textiles, in particular to a dyeing auxiliary. The dyeing auxiliary comprises the following components by weight: 1-5 parts of chitosan, 2-5 parts of chlorogenic acid, 1-3 parts of sodium polyacrylate, 2-6 parts of dye-fixing agent NFC, 2-12 parts of levelling agent SE, 1-3 parts of alkylphenol ethoxylates, 2-5 parts of succinic alkyl ester sulfonates, 8-15 parts of polyether modified silicone, 1-3 parts of polyving akohol, 1-3 parts of crosslinking agent MH, and proper amount of small molecule water. The invention further relates to a preparation method of the dyeing auxiliary. By using the dyeing auxiliary, the color fastness and the color sharpness of a blended fabric are improved, the blended fabric is evenly dyed and is soft and comfortable, besides, the destroy of the fiber property of a fiber molecule of the blended fabric, caused by a dyeing agent, is also reduced, and the quality of the blended fabric is improved.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a dyeing auxiliary and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, more and more fabrics are composed of various fibers, and the proportion of textile fabrics is increasing year by year. At present, some popular clothing fabrics contain at least 2-3 kinds of fibers. Most contain 4-6 kinds of fibers. Compared with single fabrics, the dyeing process of blended interwoven products is more difficult. Therefore, on the basis of fully understanding the problems existing in the dyeing process of blended interwoven products, choose suitable dyes, formulate suitable dyeing prescriptions and process conditions for dyeing, and supplement them with appropriate The pre-treatment and post-finishing process is very important. [0003] At present, in the printing and dyeing process of blended textiles, due to the dist...
