Rubber article containing a reinforcing yarn of cellulose |
摘要 |
Cellulose extrudates can be made from an optically anisotropic solution containing 94-100 wt % of: cellulose; phosphoric acid and/or its anhydrides; and water by extruding the solution, coagulating the formed extrudates, and then aftertreating those extrudates so that they have a degree of acidity which at least equals 7. Fibers obtained by such a processs possess particularly good thermal stability and are suitable for use as a reinforcing material.
