Novel process for spinning polyacrylonitrile fibers / Frank-Günter Niemz in CHEMICAL FIBERS INTERNATIONAL, Vol. 66, N° 1 (03/2016)
![]()
[article]
Titre : Novel process for spinning polyacrylonitrile fibers Type de document : texte imprimé Auteurs : Frank-Günter Niemz, Auteur ; Thomas Schulze, Auteur Année de publication : 2016 Article en page(s) : p. 33-35 Langues : Anglais (eng) Catégories : Fibres textiles synthétiques
Filature
Liquides ioniques
PolyacrylonitrileIndex. décimale : 677.4 Textiles artificiels Résumé : The presented results deal with scientific, experimental and technical aspects of the development of a novel fiber spinning technology for polyacrylonitrile (PAN) dissolved in ionic liquids. Beside procedural investigations covering the variation of fiber forming conditions in spinneret, in coagulation baths and in different after-stretching steps, the complex influence of parameters on fiber properties in gel as well as dried state is in the main locus. In this way, individual fiber tenacities of more than 75 cN/tex and elongation values of 8-15% have been obtained. Note de contenu : - Preparation of spinning solutions
- Fiber preparation
- Fiber spinning
- Preparation of dried PAN precursor filaments
- FIGURES : 1. Cations and anions for designing ionic liquids useful for preparing polyacrylonitrile solutions - 2. Viscosity curves in dependence on shear conditions taken from a solution of 25% PAN in a PRIF at 85°C - 3. Scanning electron microscopic image of fibers spun from PRIF-solutions (cross-section and surface details - 4. Maximum allowed draw ratio as a function of PAN concentration
- TABLES : 1. Textile-physical values of PAN fibers spun from 25 wt% solution in coagulation bathes of different concentrations - 2. Filament properties before and after thermal stretching - 3. Debye-Scherrer-WAXS-images of aligned PAN fiber samples at different after-stretching ratiosEn ligne : https://drive.google.com/file/d/1na07TEJd0XG5xyH5Yq5tLYVT_ARCQ71E/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=25844
