Background
In recent years, with the improvement of living standard of people, the demand of textiles is more and more, and the requirements on the textiles are higher and higher, for example, the textiles are required to be bright in color, good in color fastness and the like. As a representative of modern dye industry, the reactive dye is popular in the printing and dyeing industry due to the advantages of bright color, complete chromatogram, economic process, simple operation, good leveling property, low price and the like. However, the reactive dye has the defect of difficult overcoming, the color fastness of the reactive dye is relatively poor when the reactive dye is used for dyeing dark colors, and the improvement of the color fastness by using the color fixing agent for finishing is an important measure. Reactive dyes, despite the formation of functional covalent bonds between the dye and the fibre, also suffer from reduced colour fastness and dye fallout from dyed wet fibre if the dye is hydrolysed during dyeing or if the un-bonded dye is not soaped sufficiently. Not only the color of the fabric is lightened, but also white or dyed fibers with other colors are stained, and staining and lapping phenomena are generated. In order to solve these problems, the development of novel dyes with high absorption rate, high fixation rate and high fastness is still the most effective way, but novel fixing agents should be developed synchronously.
The dye fixing agent is generally required to have the following properties: the water-soluble polyurethane emulsion has good solubility in water, stability to acid and alkali conditions, stability to ambient environment such as temperature and the like, and combination property with other auxiliaries and textile resin, safety without harmful substances and the like; meanwhile, the textile has the following properties after color fixation: the color change is small, the original hand feeling and style are kept, and the rubbing fastness, the washing fastness and the light fastness are high. From the patent literature, the last 60 and 80 years of the century are a peak period of research on color fixing agents.
