Embodiment 1

[0023] Scouring agent components:

[0024] 30 parts of didodecanyl polyglucoside (DP=1.8), 2 parts of isohexyl alcohol polyoxypropylene polyoxyethylene ether (3EO0.8PO), 4 parts of sodium polyacrylate, 8 parts of decane diphenyl ether disulfonate, The balance is water, 100 parts in total.

[0025] Preparation method of scouring agent:

[0026] A method for preparing a high-efficiency low-foaming refining agent. First, 30 parts of didodecanyl polyglucoside (DP=1.8) are slowly added to 50 parts of water, and stirred rapidly. After the solution is completely dissolved, the temperature of the solution is raised to 50°C; Slowly add 2 parts of isohexyl alcohol polyoxypropylene polyoxyethylene ether (3EO0.8PO) and stir for 30 minutes; finally add 4 parts of sodium polyacrylate and 8 parts of decane diphenyl ether disulfonate, stir well and cool to room temperature , and slowly make up the remaining water to obtain a light yellow transparent liquid.

Embodiment 2

[0028] Scouring agent components:

[0029] 35 parts of didodecanyl polyglucoside (DP=1.5), 5 parts of isooctyl alcohol polyoxypropylene polyoxyethylene ether (3EO1PO), 2 parts of sodium polyacrylate, 12 parts of dodecyl diphenyl ether disulfonate , and the balance is water, a total of 100 parts.

[0030] Preparation method of scouring agent:

[0031] A method for preparing a high-efficiency low-foaming refining agent. First, 35 parts of didodecanyl polyglucoside (DP=1.5) are slowly added to 40 parts of water, and stirred rapidly. After the solution is completely dissolved, the temperature of the solution is raised to 50°C; Slowly add 5 parts of isopolyoxypropylene polyoxyethylene ether (3EO1PO) and stir for 30 minutes; finally add 2 parts of sodium polyacrylate and 12 parts of dodecyl diphenyl ether disulfonate, stir evenly and cool to room temperature. Slowly make up the remaining water to obtain light yellowish brown transparent liquid.

Embodiment 3

[0033] Scouring agent components:

[0034] 32 parts of didodecanyl polyglucoside (DP=1.6), 3.5 parts of isooctyl alcohol polyoxypropylene polyoxyethylene ether (3EO1.2PO), 3 parts of sodium polyacrylate, undecyl diphenyl ether disulfonate 10 parts, the balance is water, a total of 100 parts.

[0035] Preparation method of scouring agent:

[0036] A method for preparing a high-efficiency low-foaming refining agent. First, 32 parts of didodecanyl polyglucoside (DP=1.6) are slowly added to 50 parts of water, and stirred rapidly. After the solution is completely dissolved, the temperature of the solution is raised to 50°C; Slowly add 3.5 parts of isooctyl alcohol polyoxypropylene polyoxyethylene ether (3EO1.2PO) and stir for 30 minutes; finally add 3 parts of sodium polyacrylate and 10 parts of undecyl diphenyl ether disulfonate, stir well and cool to Room temperature is sufficient, and the remaining water is slowly replenished to obtain a light yellow-brown transparent liquid. ...

Abstract

The invention provides an efficient low-foam refining agent, which is prepared from the following ingredients including alkyl polyglucoside, branched chain fatty alcohol polyoxypropylene polyethenoxy ether, sodium polyacrylate, alkyl diphenyl ether disulfonate and water. According to a preparation method of the efficient low-foam refining agent, firstly, the alkyl polyglucoside is added into the water; stirring is performed; after the complete dissolution, the temperature of the solution is raised to 40 to 60 DEG C; then, the branched chain fatty alcohol polyoxypropylene polyethenoxy ether is added; stirring is performed for 30 to 40 min; finally, the sodium polyacrylate and the alkyl diphenyl ether disulfonate are added; uniform stirring is performed; then, cooling is performed. The refining agent has good seepage, emulsification and dispersion effects. The efficient low-foam refining agent is applicable to high-temperature boiling and scold rolling piling process; whiteness and the hairy effect of the treated fabric are high; the subsequent processing requirements are met.

Description

technical field [0001] The invention relates to a textile auxiliary agent, in particular to a high-efficiency low-foaming refining agent and a preparation method thereof. Background technique [0002] In the printing and dyeing process, it is generally necessary to go through inspection, pretreatment, printing or dyeing, finishing and other processes to complete the printing and dyeing process. Scouring is a very important process in the pre-printing and dyeing process, which is related to the quality of printed and dyed fabrics. The main functions of the scouring agent in the scouring of cotton fabrics are: 1. Cooperate with caustic soda to remove impurities in cotton fibers, such as wax, pectin, nitrogenous substances, etc.; 2. Assist the desizing agent to remove the size on the cotton cloth, Make the fabric have good appearance and water resistance; 3. Improve the effect of printing, dyeing and finishing. However, many scouring agents contain nitrogen and phosphorus elem...
