Description
Technical Field
The invention relates to the technical field of textile chemical industry, in particular to a bio-based polyester degreasing agent, and a preparation method and application thereof.
Background
The polyester is fiber-forming high polymer prepared by esterification or transesterification and polycondensation reaction of raw materials of Poly Terephthalic Acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG), and is prepared by spinning and post-treatment. Spinning oil is added into polyester during spinning and wiredrawing, and the oil can play roles of bundling, lubrication, friction coefficient reduction, static resistance and the like; other greasy dirt can be adhered to the fabric during the later weaving, dyeing and finishing processing, transportation and storage. Oligomers of 1-3% are also produced during the polyester spinning process. These greasy dirt and oligomers can affect the dyeing and finishing process of polyester fiber or fabric, and produce color bars, color spots, white powder and other defects.
The current common degreasing process is a complex chemical and physical chemical process carried out with alkali and terylene degreasing agents at a certain temperature, and comprises the actions of infiltration, cleaning, puffing, emulsification, saponification, dispersion, chelation and the like, so that the saponification and dissolution of grease are promoted, the grease is prevented from being re-adhered to fibers, and the degreasing effect is better under alkaline or neutral conditions, but the capability of removing oligomers is general.
The penetration and the cleaning are important functions of the degreasing agent, and the first step of the degreasing process is that the degreasing liquid penetrates into the fiber under the action of the surfactant to expand the fiber and impurities; the second step is a cleaning action, i.e. after the fiber is fully wetted, the impurities are removed by the actions of heat and soaping, emulsifying, dispersing, etc. of chemicals.
In order to improve the production efficiency and reduce the energy consumption, a degreasing and dyeing one-bath two-step process is adopted at present. The effective realization of the technology is necessary to rely on a composite multifunctional polyester degreasing agent which has the advantages of acid bath resistance, rapid permeation, strong emulsifying power, high detergency, high temperature resistance, oxidation resistance, hard water resistance, low foam, good dispersibility, good biodegradability, safety and no toxicity. It is not possible to combine the above properties with a single surfactant, and it is necessary to compound several surfactants to achieve satisfactory oil removal by synergistic and synergistic effects.
At present, various polyester degreasing agents commonly used for textiles contain substances such as APEO, phosphorus and the like, so that the printing and dyeing industry faces extremely high wastewater treatment pressure. Therefore, there is a continuous need in the art for a textile polyester degreasing agent which has an environment-friendly component, has a low influence on the environment, can easily treat the generated wastewater, and can maintain a good degreasing effect.

The detergent has excellent acid and alkali resistance, good wetting, emulsifying, dispersing and defoaming performances and strong detergency. Part or all of the leveling agent and oligomer remover in the dyeing recipe can be replaced in a degreasing dyeing one-bath two-step process. The polyester degreasing agent disclosed by the invention is natural and environment-friendly in raw material source, small in damage to textiles, free of harmful substances in the generated process wastewater, free of pollution to the environment, capable of meeting the requirements of industry and good in application prospect.
