TH32637B - Processes for producing hydrophobic sheets - Google Patents

Abstract

Fabrication involves a process to improve wet tension strength as well as the hydro-expansion properties of sheets that are broken down by water for use as sheets. Wipe the dampness for cleaning in the house. Mixtures of expanded cellulose carboxymethyl with water or insoluble and/or Its salts with displacement level=0.30-0.60 and pH >_ and water-dispersible fibers are used. Go to the fragmentation step of the process to obtain the water-disintegrating plates before or after. The process of disassembling and such mixtures are filled with bases.

Claims (2)

1. Production process of water-disintegrating plates which is made from sheets of paper by Addition of alkaline solution to the solution between the fragmented strands with water and luloscar tell cemethylene and/or its salt There are specific characteristics. where the intercostal solution is fragmented with water and cellulose. Carboxymethyl and/or its salts which are sufficiently hydrophobic to insoluble in water with a substitution level of =0.30-0.60 and >_ 5.0 are added to the cellulose carboxymethyl and/ or its salt, with a solution of sodium carbonate at 80-400% by mass to make paper. at the same time do The concentration of dispersible fibers with the water and the cellulose carbohydrate, boxymethyl and/or its salts was adjusted to be between 0.5-5% by weight of the paper. and before making such a sheet of paper The paper will be placed after adding sodium carbonate and leave it. Stay still for at least 30 minutes. 2. The process according to Claim 1, which involves soaking the broken sheet with water. Soak with a solution for wet wipes.
