Abstract
The invention relates to an oven for drawing fibres at elevated temperature, which oven is on two sides opposite one another provided with guide rolls dictating a zigzag up-and-down drawing trajectory for the fibre in the oven. In the oven according to the invention the drawing trajectory is at least 20 metres long and the rolls are driven. The invention also relates to a process for drawing fibres using the oven according to the invention, in particular to a process for producing highly oriented polyethylene fibres.
Claims (18)
1. Oven for drawing fibres at elevated temperature, which oven is, on two sides opposite one another, provided with guide rolls dictating a zigzag up-and-down drawing trajectory for the fibre in the oven, characterised in that the drawing trajectory is at least 20 metres long and the guide rolls are driven.
2. Oven according to Claim 1, characterised in that the guide rolls are cylindrical and have a length of at least 20 cm, several fibres being able to be passed over the guide calls simultaneously next to one another.
3. Oven according to Claim 2, characterised in that the bending of the roll during the drawing is less than 0.1 %.
4. oven according to any one of Claims 1-3, characterised in that the drawing trajectory is at least 50 m and the oven contains at least 4 guide rolls,
5. Oven according to any one of Claims 1- 4, characterised in that the driven guide rolls are provided with devices for determining the power uptake of the driving mechanism.
6. oven according to any one of Claims 1-5, characterised in that it is provided with devices for creating a gas flow in a direction substantially perpendicular to the transport direction of the fibres between the guide rolls.
7. Oven according to any one of Claims 1-6, characterised in that it is provided with devices for heating or cooling the gas stream to create a temperature gradient in a direction perpendicular to the transport direction.
8. Oven according to any one of Claims 1-7, characterised in that the open is provided with a gas purification installation.
9. Process for drawing fibres in which use is made of an oven according to any one of Claims 1 up to and including 8.
10. Process for drying and simultaneously drawing a fibre containing solvent, characterised in that use is made of an oven according to Claim 8, the solvent removed from the fibre being recovered in the gas purification installation.
11. Process according to Claim 10, characterised in that use is made of an oven according to Claims 7 and 8, a temperature gradient having been created in the oven in the direction perpendicular to the transport direction of the fibre, with the temperature being higher at the end than at the beginning of the drawing trajectory.
12. Process for producing a highly oriented polyethylene fibre, characterised in that a lowly oriented polyethylene precursor fibre is drawn in a single step at a temperature of between 135 and 160°C and a draw ratio of at least 2.5 to form a highly oriented polyethylene fibre having a tensile modules of at least 1000 g/den and a strength of at least 30 g/den.
13. Process according to Claim 12, characterised in that the precursor fibre is drawn in an oven according to and one of Claims 1 up to and including 8.
14. Process according to Claim 12 or Claim 13, characterised in that the precursor fibre has a tensile modules of between 150 and 500 g/den and a tensile strength of between 5 g/den and 20 g/den.
15. Process according to any one of Claims 12-14, characterised in that the drawing temperature is virtually the same in all parts of the oven.
16. Process according to any one of Claims 12 -15, characterised in that the precursor fibre has been made by drying and simultaneously drawing according to Claim 10 or Claim 11 a polyethylene gel fibre containing solvent.
17. Process according to Claim 16, characterised in that the temperature of the fibre is in all parts of the fibre's trajectory through the oven more than 10°C lower than the melting temperature of the lowly oriented precursor fibre to be formed.
18. Process according to Claim 17 that the temperature of the gas is in all parts of the avers more than 10°C lower than the melting temperature of the fibre to be formed.
