Description
Technical Field
The invention relates to the field of textile printing and dyeing auxiliaries, in particular to a wide-temperature deoiling refining agent and a preparation method thereof.
Background
The chemical fiber is inevitably stained with spinning oil in the melt-blowing and wire-drawing processes, and other oil stains such as spindle oil, black engine oil, gear oil, white mineral oil and lubricating oil are possibly stained in the later weaving, dyeing and finishing, transportation processes and storage processes; cellulose fibers are obtained from nature and inevitably contain impurities such as wax and pectin. The blended fabric of chemical fiber and cellulose fiber on the market is comparatively everywhere, need deoiling and refine together to go on, and the refining mode of deoiling that is widely used on the market at present mainly has two kinds: 1) a dissolving method, in which a fabric is soaked by using an organic solvent (common volatile solvents such as diethyl ether, carbon tetrachloride, benzene and derivatives thereof, trichloroethylene and the like), and the surface of the fabric is rinsed by using a small brush, so that small greasy dirt on the surface of the fabric can be cleaned, but the production efficiency is low, large-area greasy dirt cannot be effectively removed, and the large-scale industrial application is difficult; 2) the washing method utilizes high-efficiency detergent (such as degreasing agent, stain remover and the like) to wash the fabric for multiple times, although the method can clean massive greasy dirt on the surface of the fabric, the degreasing temperature is generally higher, the process flow is longer at about 100 ℃, the cost is higher, the problems of energy consumption, wastewater discharge and the like exist, and the method is still to be perfected. The prior market often requires low oil removal temperature and is suitable for oil removal refining agents of all fibers. Cotton and other cellulosic fibers are typically dyed at temperatures around 60 ℃. The printing and dyeing mill generally heats up to about 100 ℃ to remove oil, discharges liquid, cools to 60 ℃ to dye, and has long working procedure and high energy consumption. Therefore, the customers put forward the oil removal at the temperature of below 60 ℃ without discharging liquid, and then the temperature is raised to 60 ℃ for dyeing, thereby saving water and time and reducing energy consumption.
In China, research and development personnel continuously research low-temperature oil removal in recent years, in patent publication No. CN110527601A, alkyl glycoside fatty alcohol polyoxyethylene ether, alkyl glycoside polyoxyethylene ether phosphate and alkyl glycoside polyoxyethylene ether sulfonate are used as low-temperature oil removal components of chemical fiber fabrics, and the alkyl glycoside and oil stain components in the chemical fiber fabrics are well combined, so that oil stains are favorably adsorbed and uniformly dispersed in water, and the oil stain removal agent is very suitable for removing oil in the temperature range of 70-80 ℃ of the chemical fiber fabrics. In patent publication No. CN105002022A, fatty amine polyoxyethylene ether, secondary alcohol polyoxyethylene ether, fatty alcohol polyoxyethylene ether and isomeric deca-alcohol polyoxyethylene ether are used as low-temperature deoiling components, and are particularly suitable for low-temperature deoiling of spandex fabrics, and because the system is a low-medium ethylene oxide number nonionic surfactant, the deoiling agent has low cloud point and is suitable for deoiling at 40-80 ℃.
In conclusion, the application temperature range of the existing oil removal refining agent is narrow, and the oil removal refining agent with wider application range needs to be invented to meet different industrial requirements.
