ABSTRACT:
The composition proposed in the present invention is a cellulose gel consisting of no less than 13 wt.% of hemicelluloses in an aqueous solution of a compound selected from the group consisting of carbamide, thiocarbamide, alkyl-substituted thiocarbamide derivatives, sodium thiocyanate, sodium iodide, sodium perchlorate and mixture thereof.
According to the invention, said composition is subjected to beating in an aqueous solution of said compound to a beating degree of 0-1 units by the Canadian standard.
The present invention allows the elimination of neutralization and washing from the technological process of producing paper or non-woven material thus reducing considerably the duration of the technological cycle. The ultimate breaking strength for the end product is increased by 30% and the bursting strength of 20-30%.
