Problems solved by technology

At present, there are very few varieties of refining agents that can withstand concentrated alkali above 300g / L in my country, and the quality is very unstable, especially the additives used have certain biological toxicity and are difficult to degrade, causing serious pollution to water bodies
In the market, there is no environmentally friendly refining agent that takes into account high alkali resistance, environmental protection and safety, good biodegradability, and does not contain APEO, phosphorus and heavy metals.

preparation example Construction

[0029] A preparation method of a high alkali-resistant textile scouring agent, the preparation steps are as follows:

[0030] Step 1: Preparation of surfactant stock solution: add 30-40% of the total weight of water required for the formula into the chemical tank and heat to 60-75°C, add isomeric alcohol polyoxyethylene ether, alkyl Glycoside and sodium ethoxylated alkylsulfate, the addition amount is based on the total content of the refined refining agent, after dissolving, stir for 0.5-1h to make it uniform, to obtain a mixed solution A, and set aside;

[0031] Step 2: Preparation of antifoaming agent stock solution: take another 30-40% of the water in the formula and add it to another chemical tank, and heat it to 50-60°C, and then add the antifoaming agent while stirring according to the weight ratio. Stir continuously until the solution is uniform and transparent to obtain a mixed solution B, which is set aside;

[0032] Step 3: fully mix the mixed solution A prepared i...

Abstract

The invention provides a high-alkali-resistance mild-performance safe and environment-friendly textile scouring agent. The textile scouring agent is prepared from the following components in percentage by weight: 20 to 25% of alcohol alkoxylate, 15 to 25% of alkyl glycoside, 10 to 15% of ethoxy alkyl sodium sulfate, 5% of ethylene glycol monobutyl ether, 2 to 4% of organic solvents, 0.2 to 0.8% of edetic acid, 0.5 to 1.0% of defoaming agents, and 20 to 45% of water. According to the textile scouring agent, the alcohol alkoxylate with high penetration, the alkyl glycoside with a mild performance, and the ethoxy alkyl sodium sulfate which serves as an anionic surfactant are used as active matter raw materials which almost do not irritate the skin and damage cotton, hemp, silk, leather and other high-level fabrics; the formula is basically free of harmful substance residue, high in penetration, high in cleaning capacity, and outstanding in detergency capacity, and the hand feel of a processed fabric is good.

Description

technical field [0001] The invention relates to the technical field of auxiliary agents for fabric treatment, in particular to a textile scouring agent and a preparation method thereof. Background technique [0002] The process of removing natural impurities, stains and weaving pulp from various textiles such as cotton, wool, hemp, silk and synthetic fibers by chemical and physical methods is called scouring. Scouring agent is an indispensable auxiliary in the textile printing and dyeing industry. Generally, it is a kind of compound with synergistic effects such as penetration, emulsification, dispersion, and complexation, which is obtained by a certain ratio of various anionic and nonionic surfactants and appropriate additives. things. [0003] In the refining process of existing textiles, in order to improve the refining effect and work efficiency, it is generally operated in a highly alkaline environment above 100°C. At present, there are very few varieties of refining...
