Problems solved by technology

Polyvinyl alcohol (which can contain some polyvinyl acetate) tends to coat the drying cylinder in a hard and uneven film that thickens as it dries and crepes, causing unevenness wrinkled
In addition, in order to remove the hard film, the cleaning blade is frequently used against the surface of the dryer, which will cause the surface of the dryer to wear.

Embodiment

[0075] in the following and image 3 and 4 The examples described and the results shown in the present invention demonstrate the superiority of the ionene adhesive formulations used in the present invention over conventional adhesive formulations. Table 1 below and image 3 and 4 The graph in the figure shows the results of comparative experiments. In an example, the formulation of Example 1 included a terpolymer ionene binder denoted "M", a water-based polyvinyl alcohol formulation denoted 2076 (which was obtained from Buckman Laboratories International, Inc.) and Busperse 2098 (an oil-based mold release agent, also available from Buckman Laboratories International, Inc.). The formulation of Comparative Example I contained polyvinyl alcohol (PVA), sorbitol and Triton X-100 (alkylphenol ethoxylate, 100% active). The machine used consisted of a ventilated dryer with felt on the cob side, debunizer on the table, 40-50% moisture in content, 10 % moisture out content, 16 foo...

Abstract

A method for manufacturing a creped fiber web is provided and includes providing a rotating cylindrical dryer surface, applying an ionene adhesive to the rotating cylindrical dryer surface to form an adhesive dryer surface, conveying a fiber web to the adhesive dryer surface, drying the fiber web on the adhesive dryer surface to form a dried fiber web, and creping the dried fiber web from the adhesive dryer surface. The ionene polymer can be a crosslinked polymer of an alkylamine, a haloepoxyalkane, and an amine that differs from the alkylamine, such as a terpolymer of dimethylamine, epichlorohydrin, and ethylenediamine. The ionene adhesive may further include monoammonium phosphate. The ionene polymer may be water-soluble and cationic.

Description

Background of the invention [0001] This invention relates to the manufacture of soft, absorbent tissue paper webs comprising soft, absorbent tissue paper webs, and in particular to creping such webs so that the webs have sufficient softness and bonding characteristics while enabling handling. The mode with the least difficulty. [0002] It is known in the art to form a tissue web from a slurry of water and fibers, dewater the wet web, and then at least partially dry the dewatered web. The web on the fabric is then transferred or carried onto a large steam-heated drum (known in the art as a Yankee dryer). The web usually enters the dryer cylinder along its tangential position, which is the major part surrounding the dryer cylinder, the zone where the web de-contacts from the drum. The separation zone is equipped with a creping doctor against which the paper web abuts so that the paper web itself is pushed against it, resulting in the known creped paper structure of tissue. ...
