preparation example 1-3

[0072] Color fixing agent is made by the following steps:

[0073] Step 1: Stir ammonium chloride and diethylenetriamine at a speed of 700r / min for 25min, heat up to 100°C, and keep warm for 1h to obtain mixture a;

[0074] Step 2: Add dicyandiamide and ethylene glycol to mixture A, raise the temperature to 130° C., and keep the temperature for 30 minutes to obtain mixture b;

[0075] Step 3: when the temperature of the mixture B is lowered to 90°C, add water and glacial acetic acid to obtain the mixture c;

[0076] Step 4: Add nano-chitin to the mixture C, and stir for 15 minutes at a rotating speed of 900 r / min to obtain a mixture d, which is the color fixing agent.

[0077] Wherein, the weight parts that dicyandiamide, ammonium chloride, diethylenetriamine, ethylene glycol, acetic acid, nano chitin and water add are as shown in table 1:

[0079]

preparation example 4-6

[0081] The difference between Preparation Example 4-6 and Preparation Example 3 is that: in Step 4 of Preparation Example 4-6, sodium hydroxide, gelatin and carrageenan were added. The specific color fixing agent preparation process steps are as follows:

[0082] Step 1: Stir ammonium chloride and diethylenetriamine at a speed of 700r / min for 25min, heat up to 100°C, and keep warm for 1h to obtain mixture a;

[0083] Step 2: Add dicyandiamide and ethylene glycol to mixture A, raise the temperature to 130° C., and keep the temperature for 30 minutes to obtain mixture b;

[0084] Step 3: when the temperature of the mixture B is lowered to 90°C, add water and glacial acetic acid to obtain the mixture c;

[0085] Step 4: Add sodium hydroxide, nano-chitin, gelatin and carrageenan to mixture C, and stir for 15 minutes at a rotational speed of 900 r / min to obtain mixture d, which is the color fixing agent.

[0086] Wherein, the weight parts that sodium hydroxide, gelatin and carrag...

preparation example 7-9

[0090] The difference between Preparation Example 7-9 and Preparation Example 6 is that sodium caseinate is added in Step 4 of Preparation Example 7-9. The specific color fixing agent preparation process steps are as follows:

[0091] Step 1: Stir ammonium chloride and diethylenetriamine at a speed of 700r / min for 25min, heat up to 100°C, and keep warm for 1h to obtain mixture a;

[0092] Step 2: Add dicyandiamide and ethylene glycol to mixture A, raise the temperature to 130° C., and keep the temperature for 30 minutes to obtain mixture b;

[0093] Step 3: when the temperature of the mixture B is lowered to 90°C, add water and glacial acetic acid to obtain the mixture c;

[0094] Step 4: Add sodium hydroxide, nano-chitin, gelatin, sodium caseinate and carrageenan to mixture C, and stir for 15 minutes at a rotational speed of 900 r / min to obtain mixture d, which is the color-fixing agent.

[0095] Wherein, the weight part that sodium caseinate adds is as shown in table 3:

Abstract

The invention relates to the field of cloth dyeing, in particular to a color fixing agent and a cotton cloth pad dyeing process using the color fixing agent. The color fixing agent is prepared from the following raw materials in parts by weight: 25-30 parts of dicyandiamide; 14-18 parts of ammonium chloride; 30-35 parts of diethylenetriamine; 18-24 parts of ethylene glycol; 30-35 parts of glacial acetic acid; 6-8 parts of nano chitin; and 120-130 parts of water. The cotton cloth pad dyeing process using the color fixing agent specifically includes the following process steps: S1, pretreatment; S2, dyeing; S3, washing with water; S4, finishing; and S5, shaping. The color fixing agent has the advantage of enhancing the color fixing effect.

Description

technical field [0001] The application relates to the field of cloth dyeing, more specifically, it relates to a color-fixing agent and a cotton pad dyeing process using the color-fixing agent. Background technique [0002] Along with the raising of people's living standard, people have different demands to the color of cloth, mainly dye cloth by dyeing agent, make cloth rich in visual beauty. [0003] In related technologies, the dyeing process includes: [0004] S1: Disperse the dye in water to obtain a dye solution, wherein the mass fraction of the dye is 4% (omf), and the liquor ratio is 1:60; [0005] S2: Add 60g / L sodium sulfite and 35g / L hydrosulfite to the dyeing solution; [0006] S3: Dyeing at 80°C for 60 minutes; [0007] S4: Take out the cloth and dry it. [0008] In view of the above-mentioned related technologies, the inventor believes that the cloth dyed by this method has poor washability, and the cloth is prone to fading after washing.
