Zusammenfassung: | The invention relates to a tissue paper and provides a wrinkling method for wrinkling tissue paper with excellent paper web softening property, relatively high strength, environmental friendliness and no toxicity. The method comprises the following steps of: (1) pretreatment, namely adding fine talcum powder into a pulp tank, and adding a polyelectrolyte with high charge density and low molecular weight before pulping; (2) dewatering; (3) squeezing; (4) regulating parameters of a Yankee dryer; (5) regulating angles of the Yankee dryer and a wrinkling scraper, wherein an impact angle is 80 to 85 degrees; (6) fixing a paper web, which is dewatered to semi-dry in the squeezing section, onto the Yankee dryer by use of an adhesive, drying, then transferring the paper web to the surface of the Yankee dryer, and wrinkling; and (7) adding a wrinkling accelerant composition, namely adding the wrinkling accelerant composition in a wrinkling process of the step (6), wherein the wrinkling accelerant composition is prepared from a biodegradable adhesion inhibitor, a cationic starch and carboxymethylcellulose at a ratio of 2:2:5 to 2:1:6. |
