4. Innovation process of Jinruiying (Ruying)'s key environmental protection, energy-saving and emission-reduction products - new alkali agent E in China
1. Research and development of new alkali agent
In addition to close cooperation with the above-mentioned colleges and universities and overseas companies, Jinruiying (Ruying) also cooperates with relevant well-known colleges and universities. Song Xinyuan, a teacher at Donghua University, and Jia Lixia, a doctoral student at Xinjiang University, have done a lot of application research on the new alkali agent E, and in 2003, under the guidance of Song Xinyuan, they were the first to publish an application paper in China. Because the technology of the new alkali agent E was infringed in China, our company was forced to publish a lawyer's statement in the "Printing and Dyeing" magazine in 2005. The content is as follows: XXX, a former employee of our company, resigned for personal reasons in December 2003 and was hired by a company in Ningbo. All technologies that he knew, used, and participated in the research and development during his employment in our company (including but not limited to the new color fixing agent E, commonly known as the substitute alkali agent or substitute alkali agent) belong to the intellectual property rights of our company and are protected by law and shall not be infringed. After XXX leaves the company (including the Ningbo company that hired him), if there is any infringement of the company's intellectual property rights or any other behavior, he will be held legally responsible upon discovery. All other behaviors of XXX after leaving the company have nothing to do with the company.
Our company successfully developed a new alkali agent E (new alkali agent S) (density 1.50, dosage is only 0.6-3.2g/L) at the beginning of its establishment in 2000.
The new alkali agent E has a narrow application range and can only dye the black color of cotton yarn. Due to continuous improvement, it has made major breakthroughs since 2003, and has been gradually improved since 2004, 2005, and 2006. It has developed a series of new alkali agent E products that are now widely welcomed by factories such as Foshan Helirong Knitting Bleaching and Dyeing Co., Ltd., Nanhai Hengxing Printing and Dyeing Co., Ltd., Minsen (Zhongshan) Textile Printing and Dyeing Co., Ltd., Guangzhou Hengfeng Printing and Dyeing Co., Ltd., Xinhui Guanhua Knitting Factory Co., Ltd., Foshan Nanfang Printing and Dyeing Factory, Zhongshan Lianhua Printing and Dyeing Co., Ltd., Qingdao Detai Thread Co., Ltd., Shandong Mingfu Dyeing Co., Ltd., Zhejiang Furun Printing and Dyeing Co., Ltd., Shaoxing County Jinxianghui Textile Printing and Dyeing Co., Ltd., Wuxi Yishun Textile Finishing Factory, Yancheng Jiangzhou Dyeing and Finishing Co., Ltd., and Yancheng Printing and Dyeing Co., Ltd. Practice has proved that the new alkali agent E (new alkali agent S) has good stability, low dosage, and meets ecological and environmental protection requirements.
2. Honors of New Alkali Agent E
On October 19, 2006, at the China National Textile and Apparel Council Science and Technology Award Ceremony held in the Great Hall of the People in Beijing, the research and development and application of New Alkali Agent E won the second prize. New Alkali Agent E fills the domestic gap and reaches the advanced level of similar international products.
On October 18, 2007, the development and application of New Alkali Agent E was included in the first batch of recommended advanced technologies for energy conservation and emission reduction in China's printing and dyeing industry.
On March 26, 2008, it was awarded the "Eleventh Five-Year Plan" Textile Industry Promotion Technology Project Certificate at the Textile Science and Technology Work Conference of the China National Textile and Apparel Council.

8. Results and Discussion:
The new alkali agent E is an optimized alkali agent for reactive dyeing process, with good buffering effect. In the process of reactive dyeing of cellulose fiber and its blends, it can replace the soda ash in the traditional process with 1/8-1/10 amount, and provide controllable synchronous dyeing and fixation. The buffer medium promotes controllable synchronous dyeing, and its buffering effect is particularly suitable for pH-sensitive dyes. Good leveling property Even for dyeing with small bath ratio, it can slow down the dyeing fixation rate. And it does not affect the color yield. For more sensitive colors, it can well overcome color flowers and layer differences (cheese dyeing). Good washing property It is very convenient to wash after dyeing (even HAC neutralization can be omitted), especially for dark colors, which can improve and enhance wet friction fastness. Even if the water quality of the dyeing plant is poor and the concentration of calcium and magnesium ions is high, there is no white spot caused by residual carbonate that cannot be washed away by soda ash. The liquid material is very convenient, improving the working environment and strength of workers, saving land for dyeing plant warehouses due to the small amount used, and facilitating warehouse storage management. Widely and efficiently applicable to various equipment, various reactive dyes and simultaneous dyeing and fixing under different bath ratio conditions. Chemical material: must be diluted with 3 times water before adding to the dye bath. If adding material to the return water, wait until the return water volume exceeds 70% and stir before adding. Adding material: can be added twice or once, and the one-time addition must be curved (rate 60-70%). If there is an automatic injection system, it can be manually controlled to be slow first and then fast, that is, only 1/3 of the material can be added in the first 2/3 of the time.
Reactive dyes are used to dye cellulose fibers, and the new alkali E is used to replace the soda ash in the traditional process. Its fixing effect is very good and the hue is relatively stable.
1/7-1/10 of the amount can be used to replace the soda ash to ensure sufficient alkalinity.
Chemical materials are easy and convenient, dispersed evenly in the dye liquor, and are not easy to produce color flowers. It is most suitable for dyeing with small bath ratios and dyeing with large molecular dyes such as turquoise.
It can be added to the dye liquor at one time to shorten the dyeing time.
It has good washability, especially for dyeing dark colors, which saves time and water, can reduce the discharge of dyeing wastewater, reduce pollution to the environment, and at the same time obtain good friction and washing fastness, and improve dyeing quality.
It is suitable for dyeing with various concentrations of reactive dyes, with good stability and reproducibility;
It does not have the problems of reduced brightness, absorption rate, discoloration, and poor reproducibility when soda ash and sodium hydroxide are used together, and there is no color flower and color instability when soda ash and trisodium phosphate are used together.
