Benefits of technology

The present invention provides a paper towel that is not only inexpensive but also has a high productivity, by using inexpensive recycled pulp, such as de-inked pulp or OCC pulp, and adjusting the contents of chemical pulp, mechanical pulp, de-inked pulp, and recycled pulp for hue. Additionally, the present invention enables efficient and inexpensive manufacturing of the paper towel by using off-line crepe processing without the need for a large equipment investment. The paper towel has a moderate stiffness, softness, and water absorbency.

Problems solved by technology

The paper towels disclosed in U.S. Pat. No. 7,449,085B2 are composed mainly of a virgin pulp, thereby being inevitably expensive.

example

[0026]Creped paper towels that were obtained by using an MICREX® / Microcreper™ system (having a width of 3,150 mm) from the original fabric for crepe processing that was produced by a twin-wire paper machine were evaluated. As a processing condition for the MICREX® / Microcreper™ system, by specifying a uniform microcreping speed of 140 mm / min (450 fpm), and varying the compaction ratio expressed as percentage (which is the difference in paper drawing speed between the Microcreper and the winder that is expressed as %), Examples 1 to 3 and Controls 1 to 3 were prepared. Control 1 did not meet the specifications for density, which is basis weight divided by caliper (μm), longitudinal stiffness, and crepe number of the present invention; Control 2 did not meet the specification for the above-described density of the present invention; and Control 3 did not meet the specifications for the above-described density and crepe number of the present invention.

Abstract

The present invention relates to a paper towel that can be provided with dry crepes with no need for involving a large equipment investment. The paper towel contains one or more of chemical pulp, mechanical pulp, de-inked pulp, and recycled pulp, being provided with crepes in an off-machine process by use of a microcreper, such as a MICREX® / Microcreper™ system, and having a basis weight of 32.2 to 64.3 gsm, a density of 0.130 to 0.150 g / cm3, which is obtained by dividing the basis weight by the caliper (μm), and the number of crepes (cpi) of 12 to 30.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a paper towel, and more particularly relates to a paper towel that can be provided with dry crepes with no need for involving a large equipment investment. In addition, the present invention relates to a rolled paper towel, having a moderate stiffness, softness, and water absorbency, and being suitable for “Away From home”, in commercial and industrial settings such as office and government buildings, hotels, schools, airports, amusement parks, hospitals, highway rest stops—anywhere restroom and kitchen facilities are not in a private home.Description of the Related Art[0002]In U.S. Pat. No. 7,449,085B2, there are disclosed absorptive paper products, such as paper towels, having a combination of a high absorbent capacity and a moderate to low rate of absorbency for hand protection. More particularly, there is disclosed a low-density paper product having one or more plies essentially composed of h...
