Texturation par jet d'airProcédé de texturation au cours duquel le fil passe dans une zone turbulente d'un jet d'air à une vitesse supérieure plus rapide que celle avec laquelle il a été étiré sur le côté éloigné du jet. Sous l'action du jet, la structure du fil est ouverte, des boucles sont formés, ensuite la structure du fil est ouverte, des boucles sont formées, ensuite la structure du fil se referme encore. Certaines boucles sont fixées à l'intérieur du fil, d'autres sur sa surface. Un exemple de ce procédé est le procédé Taslan.Index. décimale : 677.4 Textiles artificiels Résumé : Within the framework of the IGF research project (21004 BR/1), material concepts based on 2 yarn formation technologies were realized at the ITM and carbon fiber/aramid /polyamide 6 (CF /AR/PA 6) and recycled carbon fiber/recycled aramid /polyamide 6 (rCF/rAR/PA 6) hybrid yarns for thermo-plastic composites meeting requirements with very good, scalable stiffness, strength, crash and im¬pact property combinations were produced. The influence of carding, draw frame and roving frame (MK1) and air texturing unit (MK2) parameters and fiber volume fractions on the mechanical pro¬perties were analyzed to develop requirements-based and defined engineered yarns and composites based on them. The investigated yarn formation technologies complement or partly compete with each other, but thereby also represent a broad technology spectrum. This generates a broad effect for the application of the results for product development in numerous German small and medium-sized enterprises (SMEs) and often on a few technologies specialized SMEs for textile technology.

Air filters made from these fibers (AntiFil project) already showed first satisfactory results in the reduction of germs, whereas satisfactory results in liquid filtration (DynaFil project) could not yet be achieved. The next step will be to apply the additives to the fibers by other methods in order to reduce the path length to the germs to be killed and to increase the concentration of the freely available reactive species.

Procédés de fabricationIndex. décimale : 677.4 Textiles artificiels Résumé : Currently, extensive investigations are being performed at the Institute of Textile Machinery and High Performance Material Technology (ITM) to gain profound insight into the yarn formation process based on planed metal staple fibers. For this purpose, the special properties of these fibers such as high abrasiveness, high brittleness and high rigidity, in addition to their strong high tendencies for plastic deformation and stick-slip motions are considered. The developed process chain based on the conventional yarn formation process consists of stretch breaking, drafting, and spinning of 100% metal spun yarns from planed metal staple fibers. According to the current developmental state, functionality of the yarn formation process from 100% planed metal staple fibers is regarded as proven. Thus, a high potential of utilizing these fibers for high-performance and cost-efficient technical applications clearly exists. Note de contenu : - Planed metal staple fibers

This paper describes a new spin finish oil with 2 general technical characteristics achieving the benefits of reducing water use, by suppressing the generation of foam in the fiber line as well as by easing the process of wastewater treatment. Of course, this new spin finish oil maintains the same very good performance as found in other products, in terms of fiber manufacturability and spinning mill processability.
