Description
Technical Field
The invention belongs to the technical field of preparation and application of paste, and particularly relates to an oil/water phase emulsified paste for disperse dye printing of polyester fabrics, and a preparation method and application thereof.
Background
The printing paste is a high molecular compound which has a thickening effect in color paste and can be dispersed in water to prepare a thick colloidal solution with a certain concentration. In the actual printing process of the textile, the paste is a carrier for transferring the dye and the chemicals in the printing paste to the textile and is the main component of the printing paste. Although the factors affecting the printing quality are manifold, the properties of the printing paste determine the final printing effect of the fabric to a large extent and are key factors affecting the printing effect.
The short-process dyeing technology of the printing and dyeing products is one of important development directions of energy-saving emission-reducing clean production. Compared with the conventional disperse dye dyeing method, the disperse dye alkaline dyeing method adopted by the polyester fabric has considerable advantages in the aspects of process rationalization, dyeing quality improvement and the like, and the alkaline bath dyeing can be carried out in one bath for pretreatment and dyeing, so that the process is simplified, the time of the polyester fabric processing process is shortened, the washing times in the polyester fabric processing process are reduced, the production efficiency is improved, and the purposes of energy conservation and emission reduction are achieved. In the aspect of printing the polyester fabric, the alkaline printing of the polyester fabric is realized, the washing and neutralization processes in the pretreatment can be reduced, the reduction and cleaning are not needed, the consumption of water sources and energy sources is reduced, and the method has important significance for realizing energy conservation and emission reduction.
For a long time, sodium alginate is used as a main paste for disperse dye printing of polyester fabrics, and due to the reasons of low color yield, dark colored light, hard water resistance, high price and the like of the sodium alginate, manufacturers are always searching for the replacement products of the sodium alginate, and the selection of the paste is limited by price factors and the currently adopted high-temperature normal-pressure continuous steaming process. Therefore, the replacement of sodium alginate with low cost and high quality is a desire of many printing and dyeing mills.
In recent years, an oil/water phase emulsified paste has attracted much attention for a printing paste, but the oil/water phase emulsified paste has a low paste removal rate, is not easy to form a paste, cannot uniformly disperse a chemical auxiliary agent in a colloidal system, has a large viscosity change upon dilution, and has limited the application of the oil/water phase emulsified paste in the field of printing pastes due to the presence of these adverse factors. Therefore, the selection of a suitable oil/water emulsion paste for the disperse dye printing paste for polyester fabrics requires constant exploration and development.
