Estimating the term…
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%.
A composition for treating cellulose-containing fibrous materials containing cellulose with no less than 13 wt.% of hemicelluloses in the form of a gel in an aqueous solution of at least one compound selected from the group consisting of carbamide, thiocarbamide, alkyl-substituted derivatives of carbamide, and alkyl-substituted derivatives of thiocarbamide.
