Synthetic fibers and synthetic fiber textile materials finished with mineral oil finishes, silicone oil finishes or both can be simultaneously stripped of these finishes and dyed in one liquor comprising as essential ingredients

Simultaneous finish-stripping and dyeing of synthetic fibers

Raw native fibers and textile products therefrom can be simultaneously washed and bleached in one liquor if the liquor has added to it a combination product of

Simultaneous washing and bleaching of native fibres and textile products

The invention relates to a process in which a melt is mixed with, and emulsified in a colder aqueous phase at a temperature below the crystallization point of the molten compound, the melt only solidifying in the form of the dispersed particles after the emulsification step. To this end, the melt is sprayed into the aqueous phase to form a preliminary emulsion (12) and the preliminary emulsion is finely dispersed for 0.005 s to 0.15 s in a following homogenization nozzle (8) to form an emulsion (15) which then solidifies to form the final crystal suspension. The particle size can be clearly and reproducibly adjusted through the nozzle pressure during the emulsification step. The process may be used in particular for the production of highly concentrated dispersions of high-melting organic materials.

The invention relates to new finishing mixtures, which contain fatty acid alkanolamides having softening points above 70.degree. C. as anti-blocking components, for synthetic fibers, particularly fibers of polyacrylonitrile, which are used as staple fibers. The invention also relates to the use of these finishing mixtures for the finishing of staple fibers, particularly polyacrylonitrile-based staple fibers.

Finishes for stable fibers of synthetic polymers

Improved dressings for synthetic fibers, especially acrylonitrile fibers, comprise an anion-active preparation, a polyethylene dispersion and a dicarboxylic acid semi-ester salt.
