example

[0088] An aqueous slurry comprising 3% by weight of Nothern Softwood Kraft (NSK) fibers is prepared in a conventional re-pulper. The NSK slurry is refined gently and a 2% solution of the permanent wet strength resin (Kymene™ 617) is added to the NSK stock pipe at a rate of 0.9% by weight of the total dry fibers. The absorption of the permanent wet strength resin onto the NSK fibers is enhanced by an in-line mixer. A 1% solution of the dry strength resin (carboxymethyl cellulose) is added to the NSK stock before the fan pump at a rate of 0.14% by weight of the total dry fibers. The NSK slurry is diluted to about 0.2% consistency at the fan pump.

[0089] A chemical softening composition is prepared comprising di-hard tallow diethyl ester dimethyl quaternary ammonium chloride and polyoxyethylene glycol, having an average molecular weight of 400 (PEG-400). The PEG-400 was heated to about 66° C., and the quat is dissolved into the molten PEG-400 so that a homogeneous mixture is formed.

Abstract

A paper tissue such as a facial tissue or a disposable handkerchief and a method for making a tissue paper product from a tissue paper web. The method comprises the steps of passing the tissue paper web through an embossing nip formed between a first and a second embossing roll, wherein at least one of the embossing rolls comprises at least 30 embossing elements per square centimeter; and passing the tissue paper web through a calendering nip formed between a first and a second calendering roll, wherein the first and the second calendering roll are in contact with the tissue paper web over a contact length measured parallel to the direction of the axis of the first calendering roll exert a pressure onto the paper web of at least 50 N per centimeter of the contact length.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation-in-part of International Application PCT / US02 / 04615, with an international filing date of Feb. 15, 2002.FIELD OF THE INVENTION [0002] The present invention relates to paper tissue products, such as, for example, facial tissue and disposable handkerchiefs. More particularly, the invention relates to converting steps for such tissue paper products, namely embossing and calendering. BACKGROUND OF THE INVENTION [0003] Paper webs or sheets, sometimes called tissue or paper tissue webs or sheets, and products made therefrom, such as paper handkerchiefs, sometimes also called facial tissues, find extensive use in modern society. Such items as facial and toilet tissues and kitchen towels are staple items of commerce, all of which are herein referred to as paper tissue products. It has long been recognized that important physical attributes of these products are their strength and thickness / caliper, their softne...
