Description

Technical Field

[0001] This invention relates to the field of fabric degreasing agents, and in particular to an anti-re-staining emulsified degreasing agent for synthetic fiber sports fabrics and its preparation method. Background Technology

[0002] Currently, synthetic fiber fabrics occupy an important position in the fields of clothing, home furnishings, and industrial textiles due to their advantages such as wear resistance, durability, ease of care, wrinkle resistance, and low production costs. During the weaving process of synthetic fiber fabrics, spinning oils, such as mineral oil and silicone oil, are usually added to improve fiber cohesion, protect fiber strength, and reduce breakage rate. However, the current weaving process widely uses a wide variety of inferior oils to reduce costs, significantly increasing the difficulty of degreasing during pre-dyeing and printing treatment.

[0003] At the same time, these oils have hydrophobic properties. After being peeled off from the fibers, they are very easy to re-adhere to the fabric or equipment due to the affinity between them and the chemical fibers and the oleophilicity of the oxide film on the metal surface of the equipment, forming secondary pollution, which in turn leads to defects such as oil spots and white spots in subsequent dyeing.

[0004] Traditional degreasing agents mostly rely on conventional surfactants and phosphorus-containing detergents. These components not only have poor biodegradability, easily causing eutrophication of water bodies, but also have a narrow applicable range of hydrophilic-lipophilic balance (HLB) values, making it difficult to effectively match the emulsification requirements of diverse oils. In actual processes, if the oil is not fully emulsified and dispersed in the working solution, back-staining can easily occur. Especially under the current guidance of energy conservation and emission reduction in the printing and dyeing industry, many high-efficiency fabrics and rapid processing technologies require degreasing agents to maintain excellent emulsification and penetration under low-temperature (50-80℃) or short-term (3-5min) conditions.

[0005] However, existing products often slow down the movement of surfactant molecules at low temperatures, resulting in insufficient penetration and peeling efficiency. This leads to incomplete removal of oil stains, and residual oil can easily adhere to equipment, forming dirt, or even causing the fabric to stick and affecting the dyeing quality.

[0006] Currently, there is great potential in developing an anti-re-adhesion emulsifying degreasing agent that enhances low-temperature emulsification penetration and improves the dispersion stability of emulsified oil droplets in the working fluid, thereby meeting the high-efficiency and environmentally friendly pretreatment requirements of chemical fiber fabrics. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-re-staining emulsifying degreasing agent for synthetic fiber sports fabrics and its preparation method.

[0008] An anti-staining emulsifying and degreasing agent for synthetic fiber sports fabrics, comprising the following raw materials by weight: 20-50 parts cashew phenol polyoxyethylene ether, 10-30 parts secondary alcohol polyoxyethylene ether, 5-15 parts fatty alcohol polyoxyethylene ether glucoside, 5-10 parts rhamnolipid, 5-10 parts diethylene glycol monobutyl ether, 20-40 parts maleic anhydride, 1-2 parts hyperbranched polylysine, 1-5 parts butanediol, 1-3 parts catalyst, 50-100 parts isomeric alcohol polyoxyethylene ether, 2-6 parts trisodium methylglycine diacetate, and 1-5 parts maleic anhydride polyethylene glycol ester-acrylic acid copolymer.

[0009] Preferably, the catalyst is concentrated sulfuric acid.

[0010] Preferably, the isomeric alcohol polyoxyethylene ether is isomeric tridecyl alcohol polyoxyethylene ether.

[0011] Preferably, the isomeric alcohol polyoxyethylene ether has an ethylene oxide addition number of 6.

[0012] Preferably, the molecular weight of the maleic anhydride polyethylene glycol ester-acrylic acid copolymer is 2000-3000. The maleic anhydride polyethylene glycol ester-acrylic acid copolymer can be prepared by the method described in reference [1].

[0013] [1] Liu Derong, Zhou Yang. Study on the dispersion effect of maleic anhydride polyethylene glycol diester-acrylic acid copolymer dispersant on calcium carbonate in nylon-6 resin [J]. Chemical Building Materials, 2008. DOI:CNKI:SUN:HXJC.0.2008-06-002. The preparation method of the above-mentioned anti-staining emulsifying and degreasing agent for synthetic fiber sports fabrics includes the following steps: S1. Preheat water to 40-50℃, add trisodium methylglycine diacetate and maleic anhydride polyethylene glycol ester-acrylic acid copolymer and stir for 10-20 minutes to obtain the preform. S2. Mix isomeric alcohol polyoxyethylene ether, maleic anhydride, hyperbranched polylysine, butanediol and catalyst, and stir under vacuum at 120-130℃ for 1-3 hours to obtain pretreated tridecyl alcohol polyoxyethylene ether. S3. Add pretreated tridecyl alcohol polyoxyethylene ether, cashew phenol polyoxyethylene ether, secondary alcohol polyoxyethylene ether, fatty alcohol polyoxyethylene ether glucoside, rhamnol lipolipide, and diethylene glycol monobutyl ether to the pre-prepared material. Stir at 50-60℃ for 10-20 minutes, cool to room temperature, let stand for 1-2 hours, and then filter.

[0014] Preferably, in S1, the stirring speed is 100-500 r / min.

[0015] Preferably, in step S2, the vacuum level is maintained at 40-80 kPa during the vacuum stirring process.

[0016] Preferably, in step S3, the stirring speed is 400-800 r / min.

[0017] Preferably, in step S3, filtration is performed using 300-mesh nylon filter cloth.

[0018] Compared with existing technologies, the present invention has the following advantages: This invention treats isomeric alcohol polyoxyethylene ethers by introducing maleic anhydride to enhance their hydrophilicity and emulsification range, while hyperbranched polylysine provides steric hindrance and dispersion stability. Utilizing the structural tunability at both ends of the isomeric alcohol polyoxyethylene ether, this invention effectively prevents oil droplet back-adhesion and significantly improves emulsification and dispersion. Furthermore, its interaction with cashew phenol polyoxyethylene ether, secondary alcohol polyoxyethylene ether, fatty alcohol polyoxyethylene ether glucoside, and rhamnolipid reduces the surface tension of the entire system and provides good fluidity over a wide pH and temperature range.

[0019] This invention can enhance the emulsification and dispersion of oil stains, providing a better environment for oil droplets during fabric pretreatment, which is beneficial to broaden the HLB value range of the degreasing agent, save process time, and make the dispersion state of the emulsified oil agent in the working solution more stable while removing oil.

[0020] This invention is more environmentally friendly, and has a high efficiency and stable oil removal effect in the low-temperature pretreatment of chemical fiber fabrics. Moreover, the synthetic fibers and their fabric products after oil removal are easier to dye and have better dyeability, making them more suitable for the production of high-end fabric products and with broad market prospects.

[0041] 0.1 mL of test oil was dropped onto the center of 5 g of polyester knitted fabric. After the oil was applied, the fabric was set at 175°C for 45 seconds using a high-temperature setting machine. The oil-wetted polyester knitted fabric was then immersed in a solution (10 g / L) of the emulsified degreasing agent obtained in Example 5 and Comparative Examples 1-2 at a temperature of 60°C.

[0043] like Figure 1 As shown, after treatment with the emulsified degreasing agent obtained in Example 5, the oil content was the lowest and the wicking height was the highest, which was significantly better than the comparative example.

[0044] The evenness of polyester knitted fabrics treated with emulsified degreasing agent in each group was determined according to the colorimetric method in GB / T 21881-2015 "Determination of evenness of acid dyes".
