Embodiment Construction

[0184] The following examples are provided to illustrate how to practice the invention. These examples are provided to help illustrate the present invention and should not be construed as limiting the scope of the present invention. The scope of the invention is limited only by the claims.

[0185] First, an aqueous slurry of northern softwood pulp (NSK) with a consistency of about 3% was prepared using a conventional pulper and fed into the headbox of the Fourdrinier paper machine through the raw material pipeline.

[0186] To impart temporary wet strength to finished products, Co-BOND 1000 is prepared  1% dispersion and it is sufficient to deliver 1% Co-BOND 1000 based on NSK fiber dry weight  The rate is added to the NSK feedstock tube. The adsorption capacity of the temporary wet strength resin is increased by passing the treated slurry through an in-line mixer.

[0187] The NSK slurry was diluted with white water in a fan pump to a concentration of about 0.2%.

Abstract

An adhesive for applying to a creping surface in the process for dry creping tissue paper is disclosed. The adhesive comprises cationic starch and optionally a polyvinyl alcohol and a water-soluble, thermosetting, cationic polyamide-epihalohydrin resin. The adhesive provides high adhesion and doctorability for dry creping.

Description

technical field [0001] The present invention relates generally to creped tissue paper products and methods. More particularly, the present invention relates to drying creped tissue paper wherein a web is formed on a Fourdrinier or similar paper machine and then secured in a semi-dry state to a drum drying cylinder with adhesive It is dried substantially completely, and the paper base is creped from the drying cylinder by a flexible creping doctor. Background of the invention [0002] Hygienic tissue paper products are widely used. Such articles are commercially provided in sizes suitable for various applications such as facial tissue, toilet tissue and absorbent tissue. The specifications of these products, ie basis weight, thickness, strength, sheet size, furnish medium, etc. are often very different, but they are interrelated by a common production method, the so-called creped papermaking process. [0003] Creping is a way of mechanically compressing paper in the machin...
