- Example 4 fiber sample 1 4 530
- Example 4 fiber sample 5 4 380
- This fiber is a lyocell type produced according to EP 1 259 564 with 3% -5% incorporated material of Ascophyllum nodosum.
- the roller is rotated at a speed of 500 rpm.

All fiber types based on a viscose process, including the algae-incorporated fibers according to the process modified according to the invention, show no signs of fibrillation in the CSF test even after a mixing time of 45 minutes. c) Fibrillation degree by shaking test and microscopic evaluation
- the friction of the fibers together during washing or finishing operations in the wet state is simulated by the following test: 8 fibers are placed in a 20 ml sample vial with 4 ml of water and for 3 hours in a laboratory shaker type RO-10 from Gerhardt, Bonn (FRG) shaken at level 12. The fibrillation behavior of the fibers is then evaluated under the microscope by counting the number of fibrils per 0.276 mm fiber length and is reported in a fibrillation value of 0 (no fibrils) to 6 (strong fibrillation).

- inventively modified viscose fibers with incorporated algae are not modal fibers in the true sense of the word, on the basis of the substantially improved physical fiber properties, significantly improved utility values can be concluded with respect to EP 1 259 564 Examples 7 and 8.
- the connection between the wet modulus of fibers and the surface shrinkage of fabrics made therefrom has long been known (Szegö, L., Faserforsch., Text. Techn. 21.10 (1970).)
- Puchegger has confirmed this relationship for viscose and modal fibers (Puchegger, F Lenzinger Ber., 55, 32-36 (1983) and Puchegger, F., Lenzinger Ber. 58, 94-99 (1985)).
