Abstract
The present invention relates in general to treated spacer fabrics and a method of preparing such spacer fabrics and more particularly to a spacer fabric being treated for imparting the spacer fabric with at least one or all of the properties selected from good flame retardancy, good oil repellency, high spray rating and low volatile emissions. Furthermore, the invention relates to the use of a specific liquid treating composition for preparing a treated spacer fabric having at least one or all of the properties selected from good flame retardancy, good oil repellency, high spray rating and low volatile emissions.

A method of preparing a treated spacer fabric, comprising the following steps:
- providing a spacer fabric of a thermoplastic polymer;
- providing a liquid treating composition comprising at least one C6-perfluoralkyl based fluoropolymer(s) and a solvent;
- treating the spacer fabric by immerging the spacer fabric into a bath of the liquid treating composition;
- removing excessive treating composition from the treated spacer fabric;
- drying the treated spacer fabric;
- and
- fixing the treated spacer fabric.
A treated spacer fabric, comprising:
- at least one spacer fabric;
- and
- at least one C6-perfluoralkyl based fluoropolymer, the treated spacer fabric being free of perfluorooctanesulfonic acid, perfluorooctane sulfonate, perfluorooctanoic acid, and flame retardants.
