processo para a obtenção de fibra integral com partìculas de carbonato de cálcio e produto complexo, contendo fibras e cargas cristalizadas em seu contato.

摘要

The invention relates to a process for obtaining fibers integral with calcium carbonate particles, in which the fibers to be treated are contacted with carbon dioxide generator means and at least one composition comprising Ca++ ions capable of reacting with the carbon dioxide so as to give "in fine" a precipitation of calcium carbonate "in situ" on the fibers. Preferably, the carbon dioxide generator used is calcium bicarbonate.
