Embodiment 1

[0030] 1. Fully stir 15 parts of isomeric C13 alcohol polyoxyethylene (12) ether, 5 parts of C12-C14 secondary alcohol polyoxyethylene (5) ether and 12 parts of deionized water at room temperature for 25 minutes to make the mixture form a colorless transparent viscous paste;

[0031] 2. Then add 50 parts of methyl silicone oil with a viscosity of 1000mpa.s, 200 parts of hydroxy silicone oil with a viscosity of 10000mpa.s, 12 parts of methyl hydrogen-containing silicone oil, 25 parts of refined castor oil, and 2 parts of ethyl silicate-40. Continue stirring for 30 minutes at room temperature to form a transparent sticky fat;

[0032] 3. Finally, add 572 parts of deionized water to the mixture at one time, stir rapidly for 20 minutes to form a milky white emulsion, and obtain a darkening and brightening finishing agent product.

Embodiment 2

[0034] 1. Fully stir 10 parts of isomeric C13 alcohol polyoxyethylene (7) ether, 20 parts of C12-C14 secondary alcohol polyoxyethylene (9) ether and 30 parts of deionized water at room temperature for 30 minutes to make the mixture form a colorless transparent viscous paste;

[0035] 2. Then add 60 parts of methyl silicone oil with a viscosity of 350mpa.s, 190 parts of hydroxy silicone oil with a viscosity of 20000mpa.s, 9.5 parts of methyl hydrogen-containing silicone oil, 28 parts of refined castor oil, and 3.8 parts of ethyl silicate-40. Continue stirring for 40 minutes at room temperature to form a transparent sticky fat;

[0036] 3. Finally, add 630 parts of deionized water to the mixture at one time, stir rapidly for 25 minutes to form a milky white emulsion, and obtain a darkening and brightening finishing agent product.

Embodiment 3

[0038] 1. Fully stir 15 parts of isomeric C13 alcohol polyoxyethylene (5) ether, 10 parts of C12-C14 secondary alcohol polyoxyethylene (12) ether and 25 parts of deionized water at room temperature for 20 minutes to make the mixture form a colorless transparent viscous paste;

[0039] 2. Then add 55 parts of methyl silicone oil with a viscosity of 500mpa.s, 220 parts of hydroxy silicone oil with a viscosity of 50000mpa.s, 9 parts of methyl hydrogen-containing silicone oil, 30 parts of refined castor oil, and 4.5 parts of ethyl silicate-40. Continue stirring for 40 minutes at room temperature to form a transparent sticky fat;

Abstract

The invention relates to a reactive dye printed fabric color-increasing brightening finishing agent and a preparation method. The reactive dye printed fabric color-increasing brightening finishing agent is prepared from the following raw materials in parts by weight: 20 to 30 parts of nonionic emulsifier, 50 to 70 parts of methylsilicone oil, 180 to 220 parts of hydroxyl silicone oil, 8 to 12 parts of methyl hydrogen silicone oil, 25 to 30 parts of refined castor oil, 1 to 5 parts of ethyl silicate-40, and 510 to 660 parts of deionized water. The reactive dye printed fabric color-increasing brightening finishing agent is prepared in a liquid crystal emulsification method and contains no ammonium and nitrogen and is soft and smooth in hand feeling and good in washability.

Description

technical field [0001] The invention relates to a finishing agent for textiles, in particular to a finishing agent for deepening and brightening reactive dye printing fabrics and a preparation method thereof. Background technique [0002] With the continuous development of textile technology, people have higher and higher requirements for clothing fabrics. One of them is the first sensory evaluation of textiles, that is, color evaluation. gentrification. Reactive dyes have become the preferred dyes for cellulose fiber printing because of their complete color spectrum and high wet fastness. Reactive dye printing, as the most mainstream printing technology, has been widely spread and widely used in pure cotton, rayon and Tencel fabric. [0003] Reactive dye printing will use a large amount of urea in the preparation of slurry to improve the vividness of the color. After printing, the slurry on the fabric must be washed off, which will cause a large amount of urea to enter th...
