Problems solved by technology

At present, due to the advantages of high strength, good wear resistance and low cost of synthetic fibers, the output is increasing year by year; and the common and difficult technical difficulty in dyeing spandex (stretch) and nylon in synthetic fibers is coloring. Insufficient, low coloring rate, large color difference after dyeing, color spots and stripes, and the gloss of the dyed fabric fiber and the color fastness after dyeing are not ideal. The light fastness is difficult to achieve the desired effect

Embodiment 1

[0027] Step 1. Add 2.0% AEO 3 , 3.0% oleyl alcohol polyoxyethylene ethers, 10.0% aliphatic secondary amines were added to the reaction kettle in turn, and the stirring speed was turned on at 300 rpm, then 50% deionized water in the formula was added, and then 5.0% acetic acid and 3.0% urea were added and stirred;

[0028] Step 2. The reaction is slowly heated up to 70-80°C and kept for 3 hours, then when the temperature is lowered to 50°C, weigh the remaining 50% of the water in the formula and add it to the reactor for 20 minutes, then add 10.0% fatty amine ether, 8.0% fatty amine polyoxyethylene ether, 8.0% fatty amine alcohol ether, 6.5% glycerin and stirred for 1 hour;

[0029] Step 3, after the stirring is completed, let it stand still, filter and discharge the material.

Embodiment 2

[0031] Step 1. Add 3.0% AEO 3 , 2.0% oleyl alcohol polyoxyethylene ethers, 15.0% aliphatic secondary amines were added to the reaction kettle in sequence, and the stirring speed was turned on at 300 rpm, then 50% deionized water in the formula was added, and then 5.0% acetic acid and 3.0% urea were added and stirred;

[0032] Step 2. The reaction is slowly heated up to 70-80°C and kept for 3 hours. Then when the temperature is lowered to 50°C, weigh the remaining 50% of the water in the formula and add it to the reactor for 20 minutes. Then add 18.0% fatty amine ether, 3.0% fatty amine polyoxyethylene ether, 8.0% fatty amine alcohol, 5.0% PEG200, 1.0% PG400 and stirred for 1 hour;

[0033] Step 3, after the stirring is completed, let it stand still, filter and discharge the material.

Embodiment 3

[0035] Step 1. Add 5.0% oleyl alcohol polyoxyethylene ethers, 20.0% secondary aliphatic amines to the reaction kettle in sequence, turn on the stirring speed of 300rpm, then add 50% deionized water in the formula, then add 6.0% citric acid, 3.0% urea stirring;

[0036] Step 2. The reaction is slowly heated up to 70-80°C and kept for 3 hours. Then when the temperature is lowered to 50°C, weigh the remaining 50% water in the formula and add it to the reaction kettle for 20 minutes. Then add 15.0% fatty amine ether, 3.0% fatty amine polyoxyethylene ether, 10.0% fatty amine alcohol ether, 6.0% PEG400; stir for 1 hour;

[0037] Step 3, after the stirring is completed, let it stand still, filter and discharge the material.

Abstract

The invention relates to the technical field of a textile finishing agent, and concretely discloses a fiber dyeing deepening agent. The textile finishing agent is prepared from the following formula raw materials in percentage by mass: 5.0.0 to 10.0 percent of emulsifiers, 10.0 to 20.0 percent of aliphatic amine, 25.0 to 35.0 percent of aliphatic amine derivatives, 3.0 percent of acid, 5.0 to 8.0 percent of aliphatic alcohol, 3.0 to 5.0 percent of urea and the balance deionized water. The fiber dyeing deepening agent has the advantages that the coloring effect on spandex (lycra) and nylon is extremely good; no allergy, no teratogenesis, no mutagenesis and no carcinogenesis are caused; no toxic and side effects are caused on the human body; the energy is saved; the environment is protected.

Description

technical field [0001] The invention relates to the technical field of textile finishing agents, in particular to a fiber dyeing deepening agent and its preparation. Background technique [0002] As a high value-added commodity, textiles often require a high-grade sense of color depth. At present, due to the advantages of high strength, good wear resistance and low cost of synthetic fibers, the output is increasing year by year; and the common and difficult technical difficulty in dyeing spandex (stretch) and nylon in synthetic fibers is coloring. Insufficient, low coloring rate, large color difference after dyeing, color spots and stripes, and the gloss of the dyed fabric fiber and the color fastness after dyeing are not ideal. The light fastness is difficult to achieve the desired effect. This is because polyester fiber has a special specular luster. When light hits its surface, a large amount of incident light will be reflected, and only a small part of the incident lig...
