Dystar Focus On Green Line To Enhance The Environmental Friendly Dyeing Concept Of Polyester Fiber.

DyStar group, based in Singapore, is expanding its Cadira program to introduce new polyester dyeing technology, which can reduce water, waste and energy consumption.

The company has always provided

And auxiliaries for textile and leather industries have increased Cadira Polyester as the second concept of Resource Efficiency Program, which aims to help brands, retailers and their suppliers to save resources and reduce carbon footprint on textiles.

The company said that the initiative used the Eliot process optimization tool, Optidye PES, combined with Dianix dyes and Sera auxiliaries to enhance the "once successful" efficiency to reduce energy, water and chemicals consumption and sewage discharge.

Besides,

It can shorten the processing time and improve the processing time.

。

DyStar explained that with the overall optimization, production efficiency can reach as high as 58%.

Washing / dyeing, reducing and cleaning in dye vans also helps to reduce water and energy consumption, while reducing cleaning alternatives can also reduce sewage discharge.

The first concept introduced by the program is the Cadira Reactive used for dyeing cellulose.

The State Administration of quality supervision, inspection and quarantine and the National Standardization Management Committee jointly issued the national standard Notice No. eighth in 2016. It was officially promulgated by the 5 standards of the PTA product standards drafted by the Yangtze Petrochemical Industries Co quality inspection center and the PTA particle size distribution. It will be implemented in January 1, 2017, thus ending the history of no unified national standard of PTA in the country, providing a "ruler" for the unification of the domestic PTA product quality standards, so as to promote the industry to further standardize the track and improve the overall quality of China's PTA production.

The 450 thousand ton / year PTA production plant, which was put into operation in 1989, was the largest in the country, and once accounted for more than 90% of the total domestic PTA market. The product quality was praised by users as "the best in the world and the best in Asia". It was once rated as a famous brand product in China and a user satisfaction product in the whole country.

The listing price of Yangzi Petrochemical PTA is regarded as the vane of the domestic market.

After pformation, Yangzi Petrochemical has 1 million 50 thousand tons / year design capacity, and has been identified as an exclusive supplier by some users. It is the first product of Yangzi Petrochemical to implement ISO9000 quality management system.

At the same time, relying on industrial equipment, the company's Research Institute and chemical plant successfully developed PTA complete technology, and used its own technology to carry out technical pformation of No. 2 PTA, reducing energy consumption by 100 kilograms of standard oil / ton PTA.

However, for a long time, there is no uniform national standard in China. Most enterprises organize production by their own standards, which has affected the standardized management of the market. Especially in recent years, private enterprises invested heavily in PTA, and domestic PTA capacity exceeded 50 million tons. China has become a big producer of PTA products.

The national standard commission commissioned the Yangzi Petrochemical to draft the PTA national standard. The purpose is to unify the domestic market product standards, solve the difficult problems that the industry standard has been difficult to carry out for a long time, standardize product quality management and improve product quality.
