The invention relates to a coating compound for fibers and to a process for the production thereof The invention relates in particular to a preparation agent for elastanes, based on a dispersion of fatty-acid metal salts and an agglomeration inhibitor in polyorganosiloxanes and mineral oils. The preparations are produced by a precipitation process from which fined-particle and sedimentation-stable dispersions with a narrow particle size distribution are obtained which are free from agglomerates.

Coating compound for fibres

This invention relates to biodegradable coating compositions based on readily biodegradable mineral oils. The invention furthermore relates to the use of the coating compositions for dressing plastic mouldings, fibers or yarns. In particular, the coating compositions exhibit advantages during further processing of elastic polyurethane fibers finished with the coating compositions or fabrics produced therefrom.

Biodegradable coating compositions

The invention relates to polyurethane compositions and especially to elastic polyurethane fibers resulting therefrom which can be employed for swimwear in aqueous, chlorine-containing environments such as swimming pools, for example. The invention relates in particular to polyurethane compositions and especially to elastic polyurethane fibers resulting therefrom that contain hydrotalcites and/or other basic metal aluminium hydroxy compounds coated with polyorganosiloxane or with a mixture of polyorganosiloxane and polyorganohydrogensiloxane.

Chlorine-resistant elastane fibres

The invention relates to a process for the production of low-gel spinning solutions-surprisingly stable in their solution viscosity-of segmented polyurethane urea elastomers in highly polar solvents, such as dimethyl formamide or dimethyl acetamide, characterized by the use of multistage jet reactor, and to a multistage jet reactor.
