| abstract | THE PRESENT INVENTION REFERS TO A PROCESS FOR THE ELABORATION OF VISCOSE CELLULAR MATERIALS BASED ON LIGNOCELLULOSE LIKE EXPIRED LEAF TREE WOODS, TREE TREES OR ANNUAL PLANTS. Lignocellulose IS FIRST PROCESSED IN AN AUTOCLAVE digester SATURATED STEAM IN ORDER TO LEAD THE HYDROLYSIS PRELIMINARY hemicellulose, THEN it IS PROCESSED WITHOUT RELAXATION WITH BLEACH (HSL) BLACK HOT FROM A PREVIOUS digests cellulose sulphate, IF REQUIRED PROCESS WITH THE INTAKE OF FRESH WHITE BLEACH (WL) MIXTURE IN ORDER TO NEUTRALIZE THE RESULTING ACID REACTION PRODUCTS, SO THAT A NEUTRALIZATION BLEACH (NL) IS FORMED IN THE DIGESTOR. AFTER THE AMOUNT REQUIRED OF ALCALI FOR THE DIGNIFICATION, BLEACH (WL) FRESH WHITE IS ADDED, IF IT IS REQUIRED ACCOMPANIED BY THE EXPULSION OF BLEACH (NL) OF NEUTRALIZATION AND REGULATION OF TEMPERATURE, WITH DIGESTION WITH OR WITHOUT A TEMPERATURE. WHEN THE DESIRED DEGREGATION DEGREE HAS BEEN REACHED, DIGESTION IS STOPPED THROUGH EXPULSION OF BLEACH (HSL) HOT WHITE WITH ALKALINE WASH FILTER (WF), SO THAT THE CELLULOSE IS REMAINING FREE FROM THE PRODUCTS STILL ADHERE, AND THE CELLULOSE SO OBTAINED IS DISCHARGED FROM THE DIGESTOR AT A TEMPERATURE BELOW 100 |
