The rapid development of the textile industry has greatly increased the demand for dye textile chemicals, and the interdependence between the dye industry and the textile industry means that China's dye industry has a huge market prospect. The output of chemical fibers in my country has grown from 2.8019 million tons in 1994 to 11.6137 million tons in 2003, and new fibers such as ppt and pla are under development. As the country adopts new measures to adapt to the cancellation of textile export quotas and encourages the export of high value-added textiles and clothing, the demand for textile auxiliaries will increase accordingly. In 2005, China's total output of dyes and organic pigments reached 797,000 tons, a year-on-year increase of 7.4%, which not only met the domestic textile demand, but also promoted the development of the textile industry. This is also an important opportunity for my country to further develop textile auxiliaries.

The production of printing and dyeing auxiliaries in my country is progressing with the development of textile printing and dyeing industry. Since the 1990s, the development of new fibers, the innovation of textile technology, the improvement of consumption level and the increase of export volume have forced the textile industry to seek new auxiliaries and new business models. From the beginning of import to the nationwide development and production, the embryonic form of the printing and dyeing auxiliaries production industry intersecting the chemical industry and the textile industry has gradually formed. Today, the products are developing towards high-end, comfortable, healthy and ecological green. The development trend of textile printing and dyeing auxiliaries has four aspects: develop corresponding auxiliary auxiliaries according to the development of new fibers; Textile printing and dyeing auxiliaries; development of environmentally friendly auxiliaries. In order to adapt to the new development trend, the textile printing and dyeing industry needs to continuously inject fresh blood to maintain the diversified development of production and operation.

Example 6 Performance test of the composition of the present invention in printing and dyeing

1. Emulsification performance test

1.1 Test method

Emulsification is related to degreasing property, and the requirements for emulsification are different for fabrics of different fibers. It is generally believed that the stronger the emulsifying performance, the stronger the degreasing function. The present invention adopts emulsifying performance test method as follows: take 100mL of the working fluid to be tested in a 300mL beaker, drop 1 to 2 drops of engine oil, observe the phenomenon, then stir rapidly with a stirrer for 10 to 20min (fix a stirring speed, stir in this embodiment The rotation speed of the device is 100r/min) and start timing, record the time when the solution stratifies at 25°C, 60°C, 80°C and other temperatures.

1.2 Results and discussion

Table 1 Emulsification performance test results of the composition of the present invention

Compared with glyceryl monostearate, ^* P<0.05, ^** P<0.01;

With polyoxyethylene ether fatty acid soap, ^# P＜0.05, ^## P＜0.01;

When the engine oil is added to the working fluid, it will disperse immediately, and an emulsion can be formed after high-speed stirring. It is generally believed that the emulsification of the auxiliary agent that does not appear within 30 minutes is better. On the contrary, when the oil drops into the working liquid, it will immediately stratify or float on the liquid surface in the form of oil droplets, and the additives that will stratify quickly after stirring have poor emulsification. As can be seen from Table 1, when the composition of the present invention is used alone relative to glyceryl monostearate and polyoxyethylene ether fatty acid soap, the delamination time is significantly increased, and the two components show a certain synergy in improving the emulsification performance , wherein the emulsifying performance of composition 3 is more excellent than that of other compositions.

2. Compatibility test with other additives

2.1. method

Take 100mL of the working solution to be tested, adjust the pH value and temperature, then add 10mL of the working solution of other additives, stir, let it stand, and observe the layering phenomenon of the solution. Other additives in this example are commonly used organic acids and organic acid halides. The test results are shown in Table 2.

2.2 Results and discussion

         Table 2 Compatibility Effects of the Composition of the Present Invention and Other Adjuvants

Whether an additive matches other additives depends mainly on whether the working fluid is stable after mixing. Generally speaking, if there is no stratification, no precipitation, no bubble formation and little change in viscosity, it can be considered that the matching is good and can be used in the same bath. It can be seen from Table 2 that the composition of the present invention and commonly used auxiliaries in the field of printing and dyeing are stable for long-term storage under various proportions and different pHs, no stratification occurs, and the solid content is below 10%. This shows that when the composition of the present invention is used as an auxiliary agent in the field of printing and dyeing, it has good compatibility with other auxiliary agents and has a wide range of applications.
