A method for forming an insulation product based on a composite of mineral wool and another first material comprising the steps of: (1) forming mineral wool fibers using at least one fiberizing device; (2) introducing the first material to the formed mineral wool fibers at a location proximate the fiberizing device to form a first mixture; (3) drawing the first mixture into a collector to form a structure having a predetermined thickness; and (4) subsequently processing the first mixture to form the insulation product, wherein the first material is disposed throughout the insulation product.

Provided is a process and apparatus for applying a liquid binder to fibers. The process involves introducing heat curable liquid binder onto moving fibers by atomizing the liquid binder and applying the atomized binder from a point within the moving column of fibers. Better binder efficiency and a more efficient overall process is realized.

In an insulation blanket-packaging machine and method for continuously packaging insulation blanket in the form of batts there is a continuous: infeed of batts into a loading station; movement of batts from the loading station into a transfer station that also functions as a batt-stacking station; formation of a batt stack in the transfer station; compression of a batt stack in a compression station; envelopment of a compressed batt stack within sheet material in a packaging station to form a package; and removal of a package from the machine. The machine can also be used to package insulation blanket in roll form.

Resilient battery separator media, especially adapted for use as battery separators for starved electrolyte batteries, are formed from air laid, fibrous mats of randomly oriented, entangled microfibers which may be needled to further entangle the fibers. The fibrous mats may be essentially uniform in density throughout their thickness or may include one or two relatively high density, high tensile strength fibrous surface layer(s) and a relatively low density, more resilient fibrous layer integral with and, in one embodiment, intermediate the two surface layers wherein the fibers in the surface layer(s) of the mats are more entangled than the fibers in the resilient layer. The fibrous mats, with one or two surface layers, are formed from the air laid fibrous mats by further entangling the fibers at and adjacent one or both surfaces of the mats, e.g. through hydroentanglement, relative to the entanglement of the fibers in the resilient fibrous layer. The fibrous mats with substantially uniform densities may be made by flooding the air laid mats with a liquid and drawing a vacuum though the mats. Preferably, no organic binders are used in the mats. However, the fibers of the mats may be treated with an acid solution to hydrolyze the surfaces of the fibers and bond the entangled fibers together at their points of intersection.

Method of making resilient battery separator media

A resilient battery separator, especially suited for use in a starved electrolyte battery, is made of an air laid fibrous mat of randomly oriented, entangled microfibers having a mean diameter between 0.5 and 2.0 microns. The air laid mat weighs between 50 and 450 g/m.sup.2 and has a thickness between 0.01 and 0.5 inches. The fibrous mat may be essentially uniform in density throughout its thickness or may include one or two relatively high density, high tensile strength fibrous surface layer(s) and a relatively low density, more resilient fibrous layer integral with and, in one embodiment, intermediate the two surface layers. The microfibers in the surface layer(s) are more entangled than the microfibers in the resilient layer. In a starved electrolyte battery, the separator has a thickness, when subjected to a loading of 1.5 psi, that is equal to or greater than the spacing between the electrode plates of the battery and, preferably, at least 110% of the spacing between the electrode plates of the battery.

An insulated flexible air duct comprises a flexible cylindrical core; a layer of fibrous insulation blanket surrounding the flexible core and comprising a strip of fibrous blanket helically wrapped about the flexible core with lateral portions of successive convolutions of the insulation strip overlapping so that the air duct can be flexed without forming a gap between the successive convolutions of the insulation strip; and a vapor barrier jacket comprising a strip of plastic jacket film helically wrapped about the layer of fibrous insulation. The insulated, flexible air duct is formed in one continuous operation. As the flexible core is formed it is rotated about its longitudinal axis. The rotating core is fed in an axial direction through an insulation wrapping station and a vapor barrier jacket wrapping station where the fibrous insulation strip is wrapped about the core and the vapor barrier strip is helically wrapped about the insulation to form the air duct.

An insulating board is provided in which the capacity to absorb the moisture exemplified by wood fiber based board, cellulose fiber based board and perlite based board is coupled with the high permeability of fiberglass insulation to provide a board having a balance between the capacity to hold moisture and sufficient permeance to allow the board to give up the moisture as the board is passed through a cycle of absorption and desorption, whether it be on a daily or seasonable cycle.

Glass composite sheathing board

A sheathing board capable of transmitting water vapor while retaining good thermal conductivity properties. The board is formed of a core comprising rigid foamed plastic interspersed with spaced areas of water vapor permeable insulating material that extend from one major face of the core to the other. The major faces of the core are preferably faced with a water vapor permeable sheet, allowing water vapor to travel through the spaced areas of insulating material and the facing sheets. By aligning the spaced areas of material with the insulation in a wall cavity, the strength of the board and its thermal conductivity are maintained within acceptable limits.
