Abstract
"PROCESSO PARA AMOLECIMENTO DE UMA POLPACELULóSICA, PRODUTO ABSORVENTE, POLPA AMOLECIDAE MISTURA DE POLPA DE CELULOSE". A presente invençãorefere-se a processos para amolecer polpa celulósica usandoagentes de amolecimento químicos ou desagregadores, queincluem composições compreendendo ésteres de ácido de alquilabaixa ou ésteres cíclicos de compostos de poliidroxi, sem afetaradversamente a absorvência dos produtos de fibra de celulose dosmesmos, e produtos da mesma. o processo da invenção pode,também, ser usado em combinação com agentes de plastificaçãopara celulose tais como glicerol, mono- e dissacaretos, glicóis, eoligómeros dos mesmos. O processo da invenção provê fibracelulósica que é mais fácil de transformar em lanugem (formar fibrasnovamente) e subseq³entemente adensar almofadas assentadas aar formadas das fibras individualizadas resultantes, sem afetaradversamente a absorvência."PROCESS FOR SOFTENING OF A PULPACELLULOSIS, ABSORBENT PRODUCT, SOFTENED PULP AND CELLULOSE PULP MIXTURE". The present invention relates to processes for softening cellulosic pulp using chemical softening agents or disintegrators, which include compositions comprising lower alkyl acid esters or cyclic esters of polyhydroxy compounds, without adversely affecting the absorbance of the same cellulose fiber products and products thereof. . the process of the invention can also be used in combination with plasticizing agents for cellulose such as glycerol, mono- and disaccharides, glycols, eoligomers thereof. The process of the invention provides fibracellulosic which is easier to turn into fluff (to form fibers again) and subsequently to densify seated pads formed from the resulting individualized fibers, without adversely affecting absorbency.
