ABSTRACT:
A process for flameproofing organic fiber material by the dry thermal transfer process is provided. In this process, a preparation is applied to an inert carrier which is then brought into contact with the fiber materials, especially polyamide, polyacrylonitrile or linear polyester fibers; thereafter the carrier and the material to be finished are subjected to a heat treatment at not less than 80.degree. C and the finished material is then separated from the carrier.
The preparation which is applied in this process contain a phosphorus compound of the formula ##EQU1## wherein R.sub.1 and R.sub.2 are alkyl or halogenoalkyl, X is oxygen or --NH-- and Z is hydrogen, alkyl, hydroxyalkyl, halogenoalkyl, alkenyl or acyloxyalkyl.
