Problems solved by technology

However, the conductive element of a moisture indicator made of metal may cause false detection by metal detectors
The inclusion of metallic conductive elements in absorbent articles has also caused wearers trouble when attempting to pass through security doors that also have metal detectors

example 1

[0150] For exemplary purposes only, the electrical conductivity of base webs made in accordance with the present invention are described below.

[0151] The wrinkle-free through-air dried wet-laid webs made in accordance with the present invention contain conductive carbon fibers. The wrinkle-free through-air drying process used is similar to US Patents US6887348, US6736935, US6953516 and US5129988, all of which are incorporated herein by reference.

[0152]The tissue manufacturing process uses a three-layer headbox for forming the wet web. Specifically, a three-layer web was produced containing northern bleached softwood kraft pulp fibers (LL19 from Terrace Bay Pulp Company) in the two outer layers and a combination of the aforementioned softwood fibers and carbon fibers in the middle layer. mixture. The carbon fiber used was TENAX150 fiber with a chopped length of 3 mm obtained from Toho Nex Corporation. The fiber furnish used to make the middle layer contained 50% by wei...

[0158] For exemplary purposes only, the electrical conductivity of base webs made in accordance with the present invention will be described below.

[0159] Conductive nonwoven webs made according to the present invention contain conductive carbon fibers. The conductive nonwoven web was produced on a Fourdrinier 36" (Fourdrinier) paper machine located at the publicly accessible Hetty Advanced Materials Research and Development Center in Savannah, Georgia.

[0160] A monolithic web was produced containing a homogeneous blend of northern bleached softwood kraft fibers (LL19 from Terrace Bay Pulp Company), southern softwood kraft fibers (eucalyptus from Aracruz Celulose), and carbon fibers. The carbon fibers used were TENAX150 fibers with a chopped length of 3 mm obtained from Toho Nex Corporation. The fiber furnish used to make the web was 75% by weight softwood fibers and 25% hardwood fibers.

[0161] The softwood furnish was beaten to 365 degrees using a 16" Beloit DD refine...

Abstract

Conductive nonwoven webs are disclosed. The nonwoven webs contain pulp fibers combined with conductive fibers. In one embodiment, the webs are made in a wetlaid tissue making process.

Description

[0001] This application claims priority to US Patent Application No. US 11 / 888,334, filed July 31, 2007, and US Patent Application No. 12 / 130,573, filed May 30, 2008. Background technique [0002] Absorbent articles such as diapers, training pants, incontinence products, feminine hygiene products, swim underwear, and the like typically include a liquid-permeable bodyside liner, a liquid-impermeable outer cover, and an absorbent core. An absorbent core is typically positioned between the outer cover and the inner liner for absorbing and retaining fluids (such as urine) expelled by the wearer. [0003] The absorbent core can be manufactured, for example, from superabsorbent particles. Many absorbent articles, especially those manufactured by the Kimberly-Clark Company under the trade name HUGGIES TM Absorbent articles are sold with such high liquid absorption efficiency that it is sometimes difficult to tell whether an absorbent article has been soiled with bodily fluids.
