Disclosed is a variable vapor barrier for moisture control of buildings comprising or formed from a material having a moisture permeance of less than 0.1 perms (grains/h·ft2·inches of Hg) at less than 50% average humidity, such as from 10 to 50% or 20 to 40%; and a moisture permeance greater than 4, or greater than 10 perms at greater than 60% average humidity, such as from 60 to 90%, or 70 to 80%. Also disclosed are articles comprising the variable vapor barrier and methods of their use.

摘要:
The present invention relates to a gypsum board having a nonwoven liner and a gypsum core. The gypsum board of the present invention has a high work to break, resulting in a gypsum board product that has a high resistance to abuse in use. The gypsum board of the invention is also more flexible and more resistant to water and fire than paper-lined gypsum board, and does not contain nutrients that support mold growth.

This invention relates to making backwindable rod shaped batts or logs from highly oriented flash-spun continuous fibers. The fibers are conducted from the exit of a spinneret through a tunnel and into a two stage diverging nozzle to slow down the fibers for an organized collection in the collection section. The invention further includes an inflatable bladder in a discharge section for initiating the formation of the log and a mesh screen in the collection section for reducing the occurrence of fiber blow out through the gas discharge ports.
摘要:
An absorbent personal care article comprising an apertured polymer film having a first series of channels, each having a length, width and depth, on a first surface thereof and apertures having diameters at the bottoms of and along the length of said channels, said apertures extending through the thickness of the film and through a second surface of said film; and an absorbent core disposed against said second surface of said apertured film.
