Abstract:
PCT No. PCT/EP96/02827 Sec. 371 Date Mar. 17, 1998 Sec. 102(e) Date Mar. 17, 1998 PCT Filed Jun. 28, 1996 PCT Pub. No. WO97/02292 PCT Pub. Date Jan. 23, 1997Process for preparing a solution of cellulose formate from cellulose plates, in particular high-density plates, without prior mechanical destruction of these plates. The plates are dissolved directly, by means of an impregnating step of the whole plates in a base liquid of formic acid, followed by an operation of kneading of the plates thus impregnated in contact with both formic acid and phosphoric acid. The process is preferably carried out in order to prepare ready-for-spinning solutions with, in particular, if necessary, an intermediate operation of adjustment of the final composition. Solutions prepared using such a process. Preparation of objects made of cellulose, starting with these solutions, in particular fibers or films. Assemblies of such fibers or films. Articles reinforced with such fibers or films or assemblies, these reinforced articles being especially tires.
