对于纤维行业来说,利斯特已经开发出多种经过工业验证的先进工艺,以生产天然(基于纤维素)和合成纤维的纺丝浆液解决方案。

纤维工业中的主要工艺任务是将原料均匀溶解在溶剂中,得到高粘度,无瑕疵和几乎无气泡的纺丝浆液。利斯特溶解解决方案的高质量大大简化了所有下游工艺步骤,并有助于提高工厂的经济性。

纤维制造商已经发现,从利斯特溶解机出来的纺丝浆液纺制的纤维比通过常规方法生产的纤维质量更好。此外,利斯特工艺解决方案还可以应用于生产创新的功能型纤维。

应用范例

  • 纤维素基纤维(莱塞尔)
  • 合成纤维(芳纶,聚丙烯腈(PAN))

Perfect dissolving technology for very good fiber quality For decades, conventional polymerisation has been the norm in the production of elastomers. The time and cost involved in removing and treating solvents in the final stages of production were acceptable. Yet as pressure builds on manufacturers to reduce operating costs, there is greater urgency to develop processes that can help streamline costs and production techniques. One such effort has yielded extremely promising results. English 2015
Perfect fiber quality from perfect dissolving technology Fiber, filament, flies and foil are the final products of a complex process of mixing, dissolving, spinning, washing and drying of raw material. Many specialists believe that the spinning part is the only relevant processing step for the final fiber quality. This belief falls short, as the fiber quality also depends on the dissolving step before the spinning step. English 2014
Improved Lyocell dissolving system The Iyo cell fiber process is developed to transform cellulose to a man-made cotton-like fiber. The lyocell process includes a number of processing steps. The dissolving step is the most important one. It represents the heart of the lyocell technology. Kneaders developed by List AG, Arisdorf/Switzerland, are successfully applied for the continuous dissolving step whereby raw materials of different origin can be processed and transferred into a spinabie dope. English 2006
Process flexibility and process safety As world consumption of textile fibers expands with the rapid growth of Asia and other developing countries, sources of fibers other than cotton and rayon must be developed and brought to market to meet demand. Cellulose fibers (Lyocell fibers) can meet these expanding needs because of the specific qualities and characteristics of the fiber, as well as the vast availability of the raw materials. English 2004
Innovative Weiterentwicklung der Lyocell Tehnologie Der LYOCELL-Prozess ist eine moderne umweltfreundliche Möglichkeit zur Umwandlung von verschiedensten cellulosischen Rohmaterialien der Natur in Fasern, Filamente und Folien zur weiteren Verarbeitung in der Textilindustrie, der Verpackungsindustrie oder als Strukturbildner in technischen Anwendungen. Die Nassreißfestigkeit der LYOCELL-Faser übertrifft sogar die der Bauwollfaser. Deutsch 2004
Optimization of cellulose dissolution stage LIST further optimized the cellulose dissolution technology, which was introduced in 1992. This succeeded the production of excellent spinning solution qualities, produced from a variety of low cost raw materials. The technology fulfils the current high safety standards. English 2001
Continous dissolution process of cellulose in NMMO A new dissolution process for cellulose spinning solution was developed. As Basis for the new process served the classic cellulosic fiber production process. In the last 30 years or so the conventional viscose process became environmentally critical. Evaluated with regard to its environmental viability it was found to create considerable water and air pollution. This conclusion ignited the research and development of new technologies with less environmental impact. English 1999
