Abstract (en)
[origin: ES8504296A1] PREPARATION METHOD OF A FIBROUS LEAF WITH A HIGH PERCENTAGE OF LATEX. A WEIGHT RATIO BETWEEN 45 AND 140 PARTS OF FIBROUS MIXTURE PER 100 PARTS OF LATEX IS USED. THE FIBROUS MIXTURE IS COMPOSED, BY WEIGHT, OF 30 TO 90 PARTS OF CELLULOSE FIBERS AND BETWEEN 15 AND 50 PARTS OF NON-CELLULOSIC FIBERS, PREFERABLY FIBERS OF GLASS, ROCK WOOL, POLYESTER FIBER AND THE LIKE. CONTRIBUTIONS ARE PERFORMED SEQUENTIALLY: FIBROUS MIXTURE, FIRST CONTRIBUTION OF FLOCULANT, LATEX, SECOND AND THIRD CONTRIBUTION OF FLOCULANT.

Abstract (fr)
On utilise de 80 à 130 parties en poids de latex, environ, pour environ 60 à 140 parties en poids de mélange fibreux. On utilise environ 45 à 140 parties en poids sec de mélange fibreux pour 100 parties en poids sec de latex. Fabrication notamment par double floculation (ajout du ou des floculant(s) en partie avant et en partie après l'ajout de latex). Très bonnes propriétés, notamment resistance à la rupture et à la délamination.
