9. ITMA 2007 Preview Conference – dr. Angelo SabatelliFMC/BSt9 symTTec – Extrusion System symTTec stands for SYMmetry for TEChnical yarns Production of 4 ends per position Special focus is given to the melt distribution geometry over each position All yarns have the same angle from the spinneret to the first contact points, improving the filament cohesion Pulsation-free quenching has been improved to better homogenize cooling conditions of each yarn Large inlet and special spin finish applicators allows a reduction of the angle and friction of filaments at draw panel’s inlet 2 winders each with 2 ends in parallel offer a unique symmetric geometry on winding

10. ITMA 2007 Preview Conference – dr. Angelo SabatelliFMC/BSt symTTec – Draw winding position 10 Different available take up configurations 4 Duos - 4 ends5 Duos - 4 ends The use of one or other configuration depends on the yarn end-properties. CD300-winder or FW61- winder are used depending on the down-stream available equipments.

11. ITMA 2007 Preview Conference – dr. Angelo SabatelliFMC/BSt Requirements for an optimized process high process stability with optimized melt quality no overheating of the polymer material low shear rates short residence time, equal for each single polymer flow homogeneity from filament to filament (  no weak filaments!!!) Subjects for research screw geometry mixing systems (dynamic in extruder, static in melt pipes) melt pipes geometry (same length for each single polymer flow) melt distribution in the spin pack adequate filtration of the melt holes distribution in the spinneret SwissTex’s solutions Requirements for spinning part 11

12. ITMA 2007 Preview Conference – dr. Angelo SabatelliFMC/BSt12 symTTec – Extrusion System Production of 4 ends with plying for high titers Special focus is given to the melt distribution to have an adequate pipe geometry to each position and spin pack All yarns have the same angle from the spinneret to the first contact points, improving the filament cohesion Pulsation-free quenching has been improved to better homogenize cooling condition of each yarn Large inlet and special spin finish applicators allows a reduction of the angle and friction of filaments at draw panel’s inlet 2 winders each with 2 ends in parallel offers a unique symmetric geometry on winding – no difference between rear-middle-front bobbins draw panel winders spin beam

13. ITMA 2007 Preview Conference – dr. Angelo SabatelliFMC/BSt symTTec – Spinning Components Annealer - overheaters 13 SwissTex design (individual) Traditional design (common) Annealers are heaters installed below the spinnerets to reduce the yarn orientation at the take-up roll level and thereby to improve yarn draw abilities Annealers are electrically heated and removable for spin pack installation Heating height approx. 250 mm Individual position annealer with common handling, allowing a very homogenous over heating of each yarn independent of its location on the position (yarns in the middle vs yarns at the exterior)

14. ITMA 2007 Preview Conference – dr. Angelo SabatelliFMC/BSt14 symTTec – Spinning Components Cross flow quench with innovative solutions Cross flow system offers the best ratio between handling and performance Quenching has to be of perfect homogeneity Pulsation free Air speed fine tuning Easy adaptation of the airflow to the production requirement Air has to be oil free and with controlled humidity (Optional supply of A/C unit for process air) Quench cabinet is designed to give easy access to spin packs / annealers and to allow easy dismantling of rectifier for cleaning
