Description

Technical Field

[0001] The invention relates to the technical field of polymer material synthesis, in particular to a preparation method and application of a solubilizing compound for active printing. Background Art

[0002] Reactive dyes are the main dyes used for printing cellulose fiber fabrics. During the printing process of cellulose fiber fabrics, due to the viscosity of the printing paste and the requirements of various properties, the water consumption of the printing paste is low, which makes it difficult for the dye to be completely dissolved and prone to aggregation. For this reason, a large amount of hygroscopic co-solvent must be added to the reactive dye printing paste, which can absorb more water during steaming to fully swell the fiber, thereby promoting the reaction and fixation of the dye and the fiber.

[0003] In the prior art, there are many types of hygroscopic co-solvents. For example, urea is used as a hygroscopic co-solvent, but it will cause the ammonia nitrogen content in the printing wastewater to exceed the standard, thereby causing environmental problems such as eutrophication of water bodies. If its dosage is reduced, the printing effect on deep colors, bright colors, sensitive colors (such as active turquoise) and viscose fabrics will be poor. Other researchers at home and abroad have studied and developed organic small molecules, surfactants, special compounds and low-molecular polymers for use as solubilizers in reactive printing, such as organic nitrogen-containing small molecules (dicyandiamide, caprolactam, sodium ethylenediaminetetraacetic acid, etc.), but dicyandiamide is difficult to dissolve in water and difficult to disperse evenly in the color paste; such as nitrogen-free organic small molecules (triethylene glycol, diethylene glycol, glycerol, etc.), but their influence on the printing effect is not regular, so the actual operability is not strong; such as surfactants, the surfactant co-solvents currently used in reactive dye printing color paste are mainly anionic surfactants and non-ionic surfactants. The addition of surfactants can have better solubility in the printing color paste, but it may cause the viscosity of the color paste to be unstable; such as special compounds, at this stage, there are mainly Homekadol C (anionic special compound with oleic acid as the main component), JG-110 (non-ionic special compound) and compounds of polyols, surfactants and hyaluronic acid.

[0004] Although the solubilizing agents for reactive dye printing on the market have achieved certain results in specific dye structures or specific printing processes, and some research results have been put into mass industrial production, on the one hand, their effects in actual use are still far behind those of traditional processes, such as low printing color yield. On the other hand, they will also cause great environmental pressure on current textile printing companies. Summary of the invention

[0014] As a further optimization, the first emulsifier and / or the second emulsifier is a composite emulsifier, and the composite emulsifier includes an anionic emulsifier and a non-ionic emulsifier, wherein the anionic emulsifier includes sodium dodecyl sulfate and / or sodium dodecylbenzene sulfonate, and the non-ionic emulsifier includes peregal O and / or fatty alcohol polyoxyethylene ether; the sum of the masses of the first emulsifier and the second emulsifier is 1.5-5% of the total mass of the raw materials used to prepare the solubilizing polymer.

[0015] As a further optimization, the long-chain alkyl in the long-chain alkyl alcohol polyoxyethylene ether methacrylate is a C18 chain, a C20 chain or a C22 chain, and its mass is 0.05-5% of the total mass of the raw materials used to prepare the solubilizing polymer.

[0016] As a further optimization, the polymerization monomers include acrylic acid monomers, itaconic acid and acrylic esters, the acrylic acid monomers are acrylic acid and / or methacrylic acid; the acrylic esters are one or more of methyl acrylate, ethyl acrylate, butyl acrylate and methyl methacrylate; the mass ratio of the sum of the mass of the acrylic acid monomer and the itaconic acid to the mass of the acrylic esters is (0.55-0.85):1; the mass of the polymerization monomers is 3-5% of the total mass of the raw materials used to prepare the solubilizing polymer.

The solubilizing compound for reactive printing is prepared by the preparation method of the solubilizing compound for reactive printing, and the solubilizing compound for reactive printing is applied in a reactive dye printing process.

[0022] Specifically, the formula of the reactive dye printing paste using the solubilizing compound for reactive printing is:

[0023] .

[0024] The reactive dye printing process is as follows:

[0025] Reactive dye printing paste → printing → drying (100-120℃) → steaming (102-105℃, 8-12 min) → hot water washing → soap washing (95℃, 3 min, detergent 2g / L) → hot water washing → cold water washing → drying.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The solubilizing polymer formed by polymerization has a macromolecular main chain structure and a large number of anionic groups, which can generate negative charges on the macromolecular chains of the polymer. The repulsion between the negative charges can make the macromolecular chains extend as much as possible to form a larger three-dimensional space. In the steaming process after printing, it can combine with water molecules in a larger range through hydrogen bonding to form a better moisture absorption and moisturizing effect;

[0028] 2. The multifunctional cross-linking monomers used in the solubilizing polymer can enhance the three-dimensional cross-linking ability of the system, so that the anionic groups on the side chains in the system can combine with water molecules to form hydrogen bonds. The curled polymer molecular chains are extended to form a network structure through hydrogen bonding, which can improve the system's ability to bind water molecules and the network's ability to wrap and hold water, effectively improving the moisture absorption and moisturizing effects; moreover, when the dye is prepared into a printing paste, since the paste system contains less water and is uneven, the solubilizing polymer can effectively promote the dissolution and dispersion of the dye in the paste system by combining water, thereby promoting the dispersion and fixation of the dye on the fiber, which can improve the fiber's color yield and color development effect, and ensure the printing quality;

[0029] 3. Acrylic acid esters in the polymerized monomers can introduce ester groups into the molecular chain. The ester groups will be hydrolyzed under the alkaline conditions of the printing paste and the high temperature conditions of steaming to further generate anionic groups (-COO-), which can further enhance the system's ability to bind water molecules and further enhance the moisture absorption and moisturizing effects;

[0030] 4. The reactive surfactant is long-chain alkyl alcohol polyoxyethylene ether methacrylate, which introduces a hydrophobic long chain into the macromolecular chain, making the polymer macromolecule more relaxed and stretched, further improving the ability to bind water molecules during steaming, and ensuring the water-holding capacity in the subsequent color paste;

[0031] 5. The dispersibility of the dispersibility polymer is improved by compounding the dispersibility polymer with the organic solvent, which ensures the scope of action of the dispersibility polymer; and the presence of the solvent can further improve the swelling effect of the cellulose fiber;

[0032] 6. The solubilizing polymer and the solubilizing compound do not contain ammonia nitrogen and have excellent environmental protection performance; moreover, the printed fabric has excellent apparent color depth, bright color, and little influence of color light. DETAILED DESCRIPTION

[0061]

[0062] The process flow of reactive dye printing is: reactive dye printing paste → printing → drying (100-120℃) → steaming (102-105℃, 8-12 min) → hot water washing → soap washing (95℃, 3 min, detergent 2g / L) → hot water washing → cold water washing → drying.

[0063] The performance of the printed fabric after drying was tested and evaluated. Specifically, the SCT textile color measurement system (US X-Rite) and its color difference evaluation system were used to test the K / S value, Integ value, color difference value ∆E, etc. of the printed fabric, and the average value was taken for the 4 test points.
