The many benefits of wet strength resins - Paper Industry World

Cationic WSR promoters. Cationic wet strength resins are glyoxalated polyacrylamide (GPAM) derivatives indicated for the manufacturing of toilet paper, hankies and away-from-home towel grades, as they improve dispersibility of the sheet in water. Cationic WSR promoters react with cellulose to form etheric bonds.

temporary wet strength resins

Temporary Wet Strength Resins

Temporary Wet Strength Resins AKGYM® temporary wet strength resins are glyoxalated polyacrylamide based cationic polymers that improve both temporary wet and dry strength properties of toilet paper. AKGYM® firstly provides high wet strength to the paper and then allows the paper to easily decompose in water.

Preparation and characterization of crosslinked glyoxalated

To obtain additives that could simultaneously increase the dry strength and wet strength of paper sheets, we synthesized a series of crosslinked cationic glyoxalated polyacrylamide (GPAM) resins by using acrylamide (AM), 2‐methacryloxyethyl trimethyl ammonium chloride (DMC), N‐methylolacrylamide (NMA), 2‐mercaptoethanol, and glyoxal as the main materials.

New Strength Technology: Opportunities for Cost Savings and

STRENGTH RESIN Cationic glyoxalated polyacrylamide (GPAM) is a well-known strength resin [1-2] that is often regarded as a benchmark for generating dry strength. GPAM is a reactive polymer that can covalently bind with cellulose upon dehydration as shown in Fig. 1. The result is a generation of both dry and wet strength in paper.

EP0678528A1 - Aqueous solutions of polyacrylamide/glyoxal

The present invention relates to an aqueous resin solution which can be obtained by reacting a prepolymer prepared using one or more (meth) acrylamide monomers with glyoxal, the reaction mixture being diluted one or more times in this reaction and thus the reaction in two or more sub-steps is carried out, processes for their preparation and their use as crosslinking agents of hydroxyl

PULPING OF WET STRENGTH BROKE CONTAINING POLYVINYLAMIDE

We claim 1. A method of pulping wet strength paper broke composed of water-laid cellulose fibers bonded together by an adsorbed content of a normally water-soluble thermosetting cationic wet strength polyvinylamide-glyoxal resin in thermoset state, which consists essentially in: contacting said broke in aqueous medium substantially free from oxidizing agent and having a pH between 5 and 10 and
