摘要： An oral cleaning device that can fit onto a human finger is provided. The oral cleaning device, or dental wipe, is at least partially made from an elastomeric material, such as an elastomeric nonwoven, so that the wipe can more aptly fit onto a finger. Furthermore, the wipe, in some instances, can possess a barrier that is liquid-impervious, but vapor-permeable so that the finger of a user is more comfortable during cleaning. Various additives can be applied to the wipe to aid in the cleaning process.

摘要： A method of drying a paper web is provided. The method utilizes a dryer, such as a through-dryer, having a first dryer section and a second dryer section. Within the first dryer section, a relatively wet paper web is dried at an elevated temperature, such as between about 400° F. to about 500° F. After being dried by the first dryer section, the web is relatively dry and is further dried by the second dryer section at a reduced temperature, such as between about 300° F. to about 400° F. A variety of control techniques can also be utilized to control the temperature of each dryer section.

摘要： A method for softening a paper-based product, such as facial tissues, bath tissues, paper towels, etc., is provided. In particular, the method of the present invention includes exposing a cellulosic fibrous material to ionizing radiation (e.g., electron beam radiation). It is believed that the ionizing radiation induces vibrational forces throughout the cellulosic fibrous structure, thereby disrupting hydrogen bonds between adjacent fibers and opening the crystalline structure of the material to result in a softer product.

摘要： A method and apparatus for improved quenching of nonwoven filaments utilizing a turbulence inducing bar arrangement disposed in a stream of quenching gas between the quenching gas supply apparatus and the group of filaments being extruded. The bar arrangement increases the turbulence of the quenching gas so that the gas applied to the filament group has a turbulence intensity of at least about 5%. The turbulent quenching gas penetrates the interior of the filament bundle to provide more efficient removal of heat.

摘要： An apparatus and method for increasing the heating efficiency of a nonwoven web using heated air are provided. A flow modifier including a turbulence inducing bar arrangement is positioned between the heated air supply and the nonwoven web. The flow modifier increases the turbulence of the heated air before it contacts the nonwoven web, resulting in more thorough penetration of the web by the air, and better convective heat transfer between the heated air and the nonwoven web.
