- the invention relates to a process for the treatment of filler fibers with aqueous dispersions of organopolysiloxanes.
- Emulsions of crosslinked silicones are known. For the crosslinking of silicones (heavy) metal-containing or metal-free catalysts and crosslinkers are needed. In part, inhibitors are also used to control reactivity and pot life to prevent undesired too early gelation.
- DE 102004038148 A1 (corresponding WO 2006/015740 A1 ) describes the preparation of highly viscous silicones (10,000 to 50,000,000 mPa ⁇ s) in emulsion by reacting silanol-terminated organopolysiloxanes with ⁇ -aminomethylalkoxysilanes. However, no elastomeric silicone films which are insoluble in toluene are obtained.
- EP 510 631 A describes the preparation and equipment of a fiber finishing agent based on copolyesters grafted with polyorganosiloxanes for a soft feather-like Gripping on polyester filling fibers.
- the side grafting of polyorganosiloxanes to the polyester backbone gives a finishing agent that gives a smooth, low-friction feel to fibers, especially polyester filler fibers.
