Abstract

554,556. Paper of high wet strength. JACKSON, Ltd., H., and WEXLER, A. March 16, 1942, No. 5232/43. Divided out of 554,131. [Class 96] The strength, particularly the wet strength of paper &c. is increased by treatment with silicic acid made by reacting a soluble silicate with an acid solution, so that insoluble hydrated silica is bonded to the fibres when water is given off in drying, or when an insoluble silica gel is formed spontaneously. Acids used may be sulphuric or hydrochloric, or phosphoric, acetic, lactic, formic, or oxalic, or a mixture of a strong mineral acid with a little weaker acid so that a small excess of acid left in the paper is the weaker acid, the pH value of the silicic acid solution not exceeding 2.8. Alkali metal salts formed by the reaction may be removed by washing the dried paper with water or by allowing time for a silica gel to form and washing, or by removing the salts from the solution by dialysis. Excess acid in the paper may be neutralized by alkali, removed by soaking the paper, or removed with the alkali metal salts by washing after gel formation or after partially drying. The process is applicable to paper made from pulp which has been treated with a silicate and alum. The treated paper may retain high absorbency and permeability to water, or may be waterproofed by waxes, oils, or resins. The silicic acid solution may be applied to the wet web on the paper-machine. Specification 554,131 is referred to.
