Claims7
A proccess for preparing a cake of synthetic fibrids comprising:
- compressing, to hydroextract, a slurry of fibrids, to form a compression product wherein the amount of a liquid contained in the compression product is 1 to 10 times the absolutely dry weight of the fibrids;
- pulverizing the compression product containing an amount of liquid 1 to 10 times the absolutely dry weight of the fibrids, to form a pulverulent granular or flake product;
- and compressing the pulverulent product to form a solid plate-like cake containing an amount of a liquid 0.5 to 6 times the absolutely dry weight of the fibrids.
A process as set forth in claim 7, wherein the pulverulent product is compressed so that the amount of the liquid is reduced to 1 to 3 times of the absolutely dry weight of the fibrids.
