Weiterhin werden Faserfüllungen durch eine sogenannte Weichgriffausrüstung mit einem angenehmen Griff, verbesserter Flauschigkeit, verbesserter Oberflächenglätte und verbessertem Wiedererholungsvermögen ausgestattet. Für diese Weichgriffausrüstung wird gemäß Stand der Technik eine Avivage auf Silikonbasis verwendet, wie z.B. in

Examples of such dicarboxylic acid units are residues of isophthalic acid or of aliphatic dicarboxylic acids, such as glutaric acid, adipic acid and sebacic acid. Examples of modifying diol radicals are those of relatively long-chain diols, for example of propanediol or butanediol, of di- or triethylene glycol, or, if present in a small amount, of polyglycol having a molecular weight of about 500 to 2,000.

Unter silikonfrei versteht man dabei, dass sowenig silikonhaltiges Material enthalten ist, dass die erfindungsgemäßen flammhemmenden Eigenschaften nicht beeinträchtigt werden. Dies ist bei Mengen von maximal etwa 10 ppm silikonhaltigem Material in Bezug auf die ausgerüstete Hohlfaser der Fall, bevorzugt weniger als etwa 1 ppm, besonders bevorzugt weniger als etwa 0,1 ppm.Silicone-free means that silicon-containing material is contained as little as possible so that the flame retardant properties according to the invention are not impaired.
