Claims
- 1. A rubber article which can be subjected to mechanical load containing a reinforcing yarn of cellulose wherein said reinforcing yarn is obtained by a process for making cellulose extrudates from an optically anisotropic solution comprising 94-100 wt. % of the following constituents:
- Cellulose,
- Phosphoric acid and/or its anhydrides, and
- Water
- by extruding the solution to form extrudates and then coagulating the formed extrudates, said extrudates being aftertreated such that after the after treatment the extrudates have a degree of acidity which at least equals 7.
- 2. A vehicle tire containing a reinforcing varn of cellulose wherein said reinforcing yarn is obtained by a process for making cellulose extrudates from an optically anistropic solution comprising 94-100 wt % of the following constituents:
- Cellulose,
- Phosphoric acid and/or its anhydrides, and
- Water
- by extruding the solution to form extrudates and then coagulating the formed extrudates, said extrudates being aftertreated such that after the aftertreatment the extrudates have a degree of acidity which at least equals 7.
