Chemical fiber material accounts for 1/3 of textiles that are exported. The development tread of chemical fiber industry in China during early 21 century is pointed out. Introducing nanometer technology,changing physical aspect or chemical construction,new property and function are endued with chemical fiber.
The article lists a number of achievements in the application of enzyme technology in the chemical fiber material sector,discusses the utilization of biotechnology in the Chinese chemical fiber industry and forecasts the prospects of biotechnology in the development of chemical fiber industry.
The total capacity of the domestic hydrocracking units was 13.68 Mt/a in the end of 1998. Hydrocracking is an important process for production of premium intermediate distillates and feedstocks for petrochemical and synthetic fiber materials. Therefore, it will be further developed in 21st century. The catalysts, medium-pressure hydrocracking, hydroprocessing of lube oils and residue hydrocracking, etc.
It was pointed out that using the regenerated biological energy to produce chemical fiber raw material EG,the lack of PET raw material EG can be solved,the green chemical product can be developed.
This article analyses the application of the equipment of the spraied liquid glue cotton researched and produced by our university in the fabtory and introduces the relation of the product quality and the various factors, i.e. the selected chemistry material, the liquid glue, the equipment and so on.
A process control system of dual microprocessors in chemical fibre produ- ction is introduced in this paper.It contains the characteristics,construction, major functions and software design ideas of the microprocessor control system.The application of the system technology can be further extended to paper-making,sugar-refining and other production fields.
DSM is an internationally operating chemical group of companies which has its head office in the Netherlands. The numerous group companies are organized into six divisions with their production of yarn and fiber feedstocks, bydrocarbons, plastics, rubbers, resins and etc. In line with DSM's strategy for the years ahead, DSM Research BV, DSM's central research institute, is stee ring a corporate development programme which is mainly concentrated on sophisticated new materials, fine-chemical intermediates, an...
