1. Research and development of new alkaline agents
In addition to the close cooperation with the above-mentioned colleges and universities and overseas companies, Jin Ruiying (Ruiying) also cooperates with relevant well-known colleges and universities. Teacher Song Xinyuan of Xinjiang University and Jia Lixia, a doctoral student, have done a lot of applied research on the new alkali agent E, and in 2003 In 2005, under the guidance of Mr. Song Xinyuan, he published the first application paper in China. Because the technology of the new alkali agent E was violated 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, was hired by a company in Ningbo after resigning due to personal reasons in December 2003. He knew, used, and participated in all the technologies (including but not limited to new color fixing agents) that he knew, used, and participated in the research and development of during his employment in the company E, commonly known as Alkali Substitute or Alkali Substitute) belong to the intellectual property rights of our company and are protected by law and shall not be violated. After XXX resigns (including a company in Ningbo that employs him), if he infringes on the company's intellectual property rights or any other acts, he will be investigated for legal responsibility upon discovery. All other actions of XXX after resignation have nothing to do with the company.
When our company was established in 2000, it successfully developed a new type of alkali agent E (new type of alkali agent S) (the density is 1.50 and the dosage is only 0.6-3.2g/L).
The new type of alkali agent E has a narrow application range and can only dye black in cotton thread. Due to continuous improvement, a major breakthrough has been made since 2003, and it has been gradually improved since 2004, 2005, and 2006. The development is now widely accepted by Foshan and Lirong Knitting Bleaching and Dyeing Co., Ltd., Nanhai Xingxing Printing and Dyeing Co., Ltd., Minsen (Zhongshan) Textile Printing and Dyeing Co., Ltd., Guangzhou Hengfeng Printing and Dyeing Co., Ltd., Foshan Nanfang Printing and Dyeing Factory and other factories welcome new alkaline agent E and other series products. Practice has proved that the new type of alkali agent E (new type of alkali agent S) has good stability and less dosage, which meets the requirements of ecological and environmental protection.
2. The difference between the five generations of new alkaline agent E
On October 19, 2006, the new alkali agent E won the second prize at the China Textile Industry Association Science and Technology Awards Ceremony held in the Great Hall of the People in Beijing. The new type of alkaline agent E has filled the domestic gap and reached the international advanced level of similar products. New Alkali Agent E has developed five generations of products. After the transition from the first generation to the second generation, the third, fourth, and fifth generation products are more distinctive. The production and application technology has matured, and the new Alkali Agent E has developed There are five generations of products.
The first generation: excellent slow dyeing property, appearance: colorless transparent viscous liquid, small specific gravity, used for cotton knitting and cotton yarn;
The second generation: appearance: colorless transparent viscous liquid, used for cotton weaving, moderate specific gravity;
The third generation: Appearance: orange or red liquid, used for cotton weaving, with large specificity;
The fourth generation: the one most used by customers now, with excellent reproducibility, appearance: colorless transparent viscous liquid, moderate specific gravity, used for cotton knitting and cotton yarn
The fifth generation: the red color has been improved, and the color is the deepest. Appearance: orange liquid, large specificity, used for cotton knitting, cotton yarn and cotton weaving.
3. Comparison of five generations of new alkaline agent E
The first generation: especially suitable for rayon, wool and other fibers, with good brightness, good slow dyeing property, good reproducibility, easy to wash, one time of hot water washing and pickling is omitted compared with the soda ash process, and the wet rubbing fastness is improved by half a grade. Storage stable
The second generation: especially suitable for cotton woven fabrics, suitable for long-term use, with increased softness, and can directly replace alkali agents such as soda ash and caustic soda
The third generation: It can be used for cotton woven fabrics, the number of washings is reduced, and it contributes greatly to environmental protection. It can reduce the COD value and increase the fastness by half a level.
The fourth generation: Dyeing black, blue, and yellow is similar to the color of soda ash, caustic soda, and trisodium phosphate. It has good reproducibility, good level dyeing, no batch difference, easy to wash and remove, and omits one hot water wash than the soda ash process. The wet rubbing fastness to pickling is improved by half a level, and the storage stability is good
The fifth generation: it is especially suitable for factories with poor water quality. The red light and yellow light are heavier, and the blue light is slightly worse. The overall depth is better than the fourth generation. It has strong chelating power, good diffusion performance, and is easy to wash. Compared with the soda ash process, hot water washing and pickling are omitted. Wet rubbing fastness improved by half level
4. Questions about the use of new alkali agents
1. Comparison of various technical indicators and various application performances of similar products on the market
2. Problems to be paid attention to during use
For example: how to use a new type of alkali agent, what to do if the effect of some dyes is not good, etc.
3. How to transition: that is, the ratio of soda ash to substitute alkali instead, etc.
If you encounter the above problems, please contact our technical personnel directly, and our company will give technical guidance at the first time.
