"Process for the production of colorable textiles Material based on τοη derivatives of epoxy resins "

The invention relates to the production of τοη Teitilfaaern as well films, strips, shaped objects or the like., And »Was essentially based on synthetic polymers, those against dyes and especially plastic fluids dyes are particularly absorbent.

The invention particularly relates to the production of colorable textile fibers by extrusion or extrusion τοη Additions of olefinic foliar products and copolymers with derivatives τοη epoxy hareses.

The applicant is described in an earlier patent specification in a process for the production of colorable polyolefin

It has now surprisingly been found and is the subject of the invention that the processability the masses or Geaisohe based τοη polypropylene in the various technical stages (granulation, extrusion, stretching and textile finishing processes) it is greatly improved if derivatives of epoxy resins made from epiohlorohydrin are known to the polyolefins and dihydric phenols, are mixed

The derivatives of epoxy resins used in the invention are prepared by reacting epoxy resins (which contain terminal epoxy groups), which contain a primary aaine group or two secondary anine groups, in particular primary or bis-secondary aliphatic, cycloaliphatic, heterooyolisohe eels, such as n-dodecylaaine, Hexadecylaain, n-Ootadecylaain, Plperazin, 2-Methylpiperazin, 2,5-Diaethylpiperazin, 5,5,7-TriaethylhoBopiperazin, H, H · -diisopropylhezaaethylendiaain, H ₁ V * -dicyolohexylhexaaethylendiaain, N, I'-Dilsobutylheza or similar·

For the production of the epoxy derivatives that are used for ge-BaB are suitable for the invention, the epoxy resin is added to the alino compound in solution or without a solvent Tea doors "wipe 50 ° and 250 ° uagesetst"

According to the invention, polyolefins are used which are essentially composed of macromolecules with an iaotactic structure obtained by low-bridge polymerisation with the aid of stereoepesifieeher catalysts will.

The preferred crystalline polyolefin is polypropylene used, which consists essentially of macromolecules with isotactic Structure is formed, which were obtained by stereospecific polymerization of propylene The invention also applies in the same way the crystalline polyolefins are suitable, those made from monomers of the general formula

For the production of the textile fibers the additives are used Granulated and neutralized by SohmolsspinnTorriohtungen extruded, whereby without oxygen, Torsugsweis · in an atmosphere of inert oasis (nitrogen) is used.

During the process of dissolving, the polymers can also be used Opacisers, organic or inorganic color pigments, stabilizers, lubricants or such things are admitted
