ABSTRACT:
A method of producing a dyed and stabilized fiber sliver and sliver produced thereby wherein a non-twisted fiber arrangement is impregnated with a liquid for bonding the fibers, the liquid containing a dyestuff, and by application of pressure excessive or excess liquid is squeezed-off the fiber arrangement and the fibers are condensed or compacted at all sides into a compact sliver, and the individual fibers of the compact sliver at an increased or elevated temperature are mutually bonded and dyed, and the sliver is dryed. According to the invention the fiber arrangement is impregnated with a latent chemical compound activating the fiber material at the increased or elevated temperature, and the fibers after compacting into the compact sliver are dyed at the activating temperature and simultaneously are bonded mutually by the fiber material and the activating chemical compound is eliminated and the non-twisted sliver is dried.
