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.

| 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 thermoplastic composites meeting requirements with very good, scalable stiffness, strength, crash and impact 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 properties 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. |
