| abstract |
The invention relates to a method and a device for the secondary treatment of cellulose fibers, especially for reducing the fibrillation properties of lyocell fibers. According to generic methods, a cross-linking agent having at least two functional groups that chemically react with the cellulose, for example carbonyl groups, is brought into contact with the cellulose fibers. In order to further reduce, in the cellulose fiber, the content of free cross-linking agent which has not chemically reacted with the cellulose in the first secondary treatment phase without negatively influencing the reduced fibrillation tendency of the fiber, the free cross-linking agent is chemically reacted with a bisulfite compound. |
