New system concepts for spinning bicomponent filament yarns / Günter Schütt in CHEMICAL FIBERS INTERNATIONAL, Vol. 66, N° 3 (10/2016)  

[article]  inCHEMICAL FIBERS INTERNATIONAL > Vol. 66, N° 3 (10/2016) . - p. 134-136 Titre : New system concepts for spinning bicomponent filament yarns Type de document : texte imprimé Auteurs : Günter Schütt, Auteur ; Susanne Beyer, Auteur Année de publication : 2016 Article en page(s) : p. 134-136 Langues : Anglais (eng) Catégories : Fibres textiles bi-composant Filature Index. décimale : 667.4 Encres Résumé : Oerlikon Barmag and Oerlikon Neumag offer tailor-made concepts for all applications. For standard polymer and standard cross-sections, the single-temperature system is the ideal solution ; whereas the dual-temperature system is recommended for microfibers and temperature-sensitive polymers. However, most copolymers available on the market are considerably more stable and hence more temperature-independent than even a few years aga. Correspondingly, the ratio of polymers for which systematic separation of the temperature transfers right up to the spin pack is essential now lies at 5-10 %. The vast majority of cross-sections can be manufactured using the single-temperature system. This in tum has significant cost advantages in production. With the patented Oerlikon Manmade Fibers segment dual-temperature system, sensitive polymers are processed into high-quality bicomponent fibers and filaments. This concept also offers yarn producers a considerable degree of flexibility. Note de contenu : - Diverse cross-sections ensure diverse yarn properties - Eccentricity of the core - Fine yarns : bicomponent microfibers - Demanding technology - System concepts - Single-temperature system - Dual-temperature system - Special spin beam for sensitive bicomponent filament yarns - FIGURES : 1. Each cross-section provides specific properties for the bicomponent yarn - 2. Less sensitive polymers can be manufactured with the standard SP8xB bico spinning unit - 3. The new SPBxB dual temperature spin beam concept ensures the strict temperature separation between polymer type A and polymer type B En ligne : https://drive.google.com/file/d/1eqObnC2w_xqDv8ig4wi847OMP20uEenZ/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27279 [article]
