    Abstract: A multilayer fibrous nonwoven mat containing at least one transition zone comprised of a mixture of the slurries used to form the layers on each side of the transition zone, the transition zone having a thickness of at least 1 percent of the thickness of the mat. At least one of the layers contains glass fibers. The multilayer mats are particularly useful as facers on gypsum wall board, insulating foam, a wood material and a broad range of other materials. The multilayer mats are made by a method that involves using a lamella in the forming box on a wet laid mat machine, between slurries, the lamella ending a significant distance prior to a moving forming wire. The transition zone or zones provide superior interlaminar shear strength and other properties compared to multilayer fibrous mats produced on wet laid machines having two or more separate forming boxes.

    Abstract: A new foam coated nonwoven fibrous mat having properties particularly suited for a facer on gypsum wallboard, laminates made therefrom and the method of making the mat is disclosed. The mat preferably contains a major portion of glass fibers and a minor portion of a resinous binder. The foam coating is permeable and reduces fiber dust and abrasion experienced in the past with relatively coarse, relatively inexpensive glass fibers in the mat. Contrary to previous methods, the foam coated fibrous mat is made in-line on a wet mat forming production line by applying a wet foam binder onto a wet, fibrous web followed by drying and curing in-line.

    Abstract: Methods of making nonwoven mats having good strength after being scored and folded and particularly useful in making lightweight, compressible ceiling panels are disclosed. The mats also have excellent flame resistance. The mats include a blend comprising a major portion of glass fibers and a minor portion of man-made polymer fibers, the fibers being bound together with a cured binder containing a homopolymer or copolymer of polyacrylic acid and a polyol. The binder bonding the mat together can be cured to only a “B” stage to produce thermoformable mats or more fully cured to produce mats having the properties described above.

    Abstract: Coated and uncoated fibrous mats, and laminates containing the mat, having one or more surfactants on the fibers and binder holding the fibers together in only a portion of the thickness of the mat are disclosed. The mat contains a major portion of non-cellulosic fibers and a minor portion of cured resinous binder with the most typical fibers being glass fibers. The surfactant on the surface of the fibers causes a slurry or other liquid applied to the mat in a later process to form a board or laminate like faced gypsum board, a faced foam board, etc. to uniformaly penetrate the mat to the desired distance. Also disclosed are methods of applying the surfactant(s) to the hot, coated or uncoated, mat soon after the coated or uncoated mat exits a drying oven used in the process of making, or coating, the mat
