Description

Technical Field

[0001] This invention relates to the field of textile printing and dyeing technology, and in particular to a phosphorus-free, multifunctional, environmentally friendly scouring agent, its preparation method, and its application. Background Technology

[0002] Scouring is a crucial step in the pretreatment process of textile printing and dyeing. It refers to the scouring process that textiles undergo before dyeing and printing to remove impurities and oil stains from the fabric surface. Scouring agents are compound substances that primarily act as detergents, while also possessing synergistic effects such as penetration, emulsification, dispersion, and complexation.

[0003] Since the beginning of the 21st century, with the advancement of technology and the increasing awareness of environmental protection, the international textile market has demanded that the textile printing and dyeing industry move towards a more green and environmentally friendly direction. The promulgation of ISO 14000 and Oeko-Tex Standard 100 has prompted the printing and dyeing industry to urgently develop green and environmentally friendly scouring agents. Currently, among the commonly used scouring agents on the market, one type contains APEO (alkylphenol polyoxyethylene ether compounds), and due to the carcinogenicity of APEO, formulations containing APEO have been banned in the international market. Another type is mainly composed of organophosphates, which easily lead to eutrophication of water bodies and cause environmental pollution. Therefore, the development of environmentally friendly scouring agents has become an urgent problem to be solved in the pretreatment of textile printing and dyeing. Summary of the Invention

[0004] The purpose of this invention is to provide a phosphorus-free, multifunctional, environmentally friendly refining agent, its preparation method, and its application, which is safe, non-toxic, and environmentally friendly.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] This invention provides a phosphorus-free, multifunctional, environmentally friendly refining agent, comprising the following components in parts by weight:

[0007]

[0008] Preferably, the preparation method of the 2-propylheptanol xyloside includes: mixing 2-propylheptanol, xylose and p-toluenesulfonic acid, reacting until the xylose content is <0.1wt%, and subjecting the obtained product to alkali neutralization, vacuum distillation and bleaching in sequence to obtain the product 2-propylheptanol xyloside.

[0009] Preferably, the preparation method of the isomeric tridecyl alcohol ether carboxylic acid includes: mixing isomeric tridecyl alcohol ether, chloroacetic acid and sodium hydroxide to carry out a first reaction, mixing the obtained intermediate with sulfuric acid solution to carry out a second reaction, and then separating the liquid to obtain isomeric tridecyl alcohol ether carboxylic acid.

[0010] This invention provides a method for preparing the phosphorus-free, multifunctional, and environmentally friendly refining agent described in the above technical solution, comprising the following steps:

[0011] A phosphorus-free, multifunctional, environmentally friendly refining agent is obtained by mixing 2-ethylhexanol alkyl glycoside, 2-propylheptanol alkyl glycoside, 2-propylheptanol xyloside, and isomeric tridecyl alcohol ether carboxylic acid with water.

[0012] Preferably, the mixing of 2-ethylhexanol alkyl glycoside, 2-propylheptanol alkyl glycoside, 2-propylheptanol xyloside, and isomeric tridecyl alcohol ether carboxylic acid with water comprises: under a first stirring condition, sequentially adding 2-ethylhexanol alkyl glycoside, 2-propylheptanol alkyl glycoside, 2-propylheptanol xyloside, and isomeric tridecyl alcohol ether carboxylic acid to water, and mixing under a second stirring condition to obtain a phosphorus-free, multifunctional, environmentally friendly refining agent.

[0013] Preferably, the stirring speed under the first stirring condition is 150-200 r / min.

[0014] Preferably, the stirring speed under the second stirring condition is 240-300 r / min.

[0015] Preferably, the second stirring is carried out under normal pressure and at ≥18°C.

[0016] Preferably, the second stirring time is 30 min to 60 min.

[0017] This invention provides the application of a phosphorus-free, multifunctional, environmentally friendly scouring agent as described in the above technical solution, or a phosphorus-free, multifunctional, environmentally friendly scouring agent prepared by the preparation method described in the above technical solution, in the field of textile printing and dyeing.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The surfactants used in the phosphorus-free, multifunctional, environmentally friendly refining agent of this invention are 2-ethylhexanol alkyl glycoside, 2-propylheptanol alkyl glycoside, 2-propylheptanol xyloside, and isomeric tridecyl alcohol ether carboxylic acid, all of which are nonionic surfactants. This combination of surfactants, including alkyl glycosides, xylosides, and branched alcohols (ethers), results in a more stable formulation system, primarily using alkyl glycosides for better stability. The 2-ethylhexanol alkyl glycoside and 2-propylheptanol alkyl glycoside surfactants exhibit resistance to high concentrations of strong alkalis, while xyloside possesses strong penetrating properties. Furthermore, due to the steric hindrance effect of the branched structure, surfactants synthesized from branched alcohols (ethers) often exhibit low foaming and strong penetrating properties, thus resulting in a low-foaming, strong-penetrating, and high-concentration strong alkali-resistant compound system. A small amount of isomeric tridecyl alcohol ether carboxylic acid enhances the detergency and emulsifying ability of the formulation system.

[0020] 2. The phosphorus-free, multifunctional, environmentally friendly scouring agent of this invention is heat-resistant, easily soluble in water, acid-resistant, and hard water-resistant. It can be used in the scouring process of most cotton blended fabrics, and has a highly efficient scouring and impurity removal effect. It can be used in conventional de-sizing / boiling / bleaching processes to achieve excellent wool effect and whiteness.

[0021] 3. The phosphorus-free, multifunctional, environmentally friendly refining agent in this invention is entirely formulated from biodegradable green surfactants, and is safe and reliable.

[0022] 4. The phosphorus-free, multifunctional, environmentally friendly scouring agent of this invention does not contain alkylphenol polyoxyethylene ethers or organophosphates. The raw materials and products will not cause any pollution to the environment. It can make the textile pretreatment process simpler, more environmentally friendly, safe and non-toxic, and has good application prospects. Detailed Implementation

[0064] Performance testing

[0065] Using the scouring agents obtained in Examples 1-5 as samples, their physicochemical properties were measured respectively, including penetrating power (GB11983-2008), alkali resistance (test method below), capillary effect (FZT 01071-2008 Test method for capillary effect of textiles), whiteness (WSB-3C fully automatic whiteness tester), foaming (GB / T 13173.6-2000 Determination of foaming power of detergents), stain removal (QB / T 1224-2012), and emulsification (test method below). The results are shown in Table 1.

[0066] Alkali resistance test method: Prepare and accurately weigh 100 mL of a 2% (w / w) scouring agent aqueous solution, and slowly add sodium hydroxide (analytical alcohol) while stirring. When the solution becomes turbid, weigh the solution to obtain the amount of sodium hydroxide added, M g. Then weigh (M-1) g of solid sodium hydroxide and slowly add it to 100 mL of the 2% (w / w) scouring agent solution. Let it stand for 2 hours. If the solution is still transparent and there is no precipitation or coagulation, the alkali resistance of the 2% scouring agent is (10M-10) g / L. (In actual alkali resistance tests, the value of M is taken between 13 and 31. If the system is still a transparent solution after M reaches 31, higher alkali resistance concentration tests are not conducted, and the alkali resistance of the tested sample is directly determined to be 300 g / L.)

[0067] Emulsification performance test method: Prepare a 1.5 g / L refining agent aqueous solution. Accurately weigh 20 mL each of the refining agent solution and liquid paraffin into a 250 mL stoppered conical flask. Shake up and down 5 times, let stand for 1 minute, then shake up and down 5 more times. Repeat this process 5 times. Then, quickly pour the mixture from the conical flask into a 100 mL graduated cylinder, let it stand, and start timing. Calculate the time required for 10 mL of layers to separate. The longer the time, the better the emulsification performance.

[0068] Stability performance testing methods:

[0069] 1) High temperature stability: The sample to be tested was placed in a constant temperature water bath at 60℃±2℃ for 24 hours and then its condition was observed.

[0070] 2) Low temperature stability: The test sample was placed in a -10℃±2℃ refrigerator for 24 hours and its condition was observed.

[0071] The test results are shown in Table 1.
