摘要:
The present invention relates to a method of making a board product with fiber scrap materials, including the steps of adding a binder powder to the fiber scrap materials, processing the scrap fiber into pieces and mixing the fiber scrap materials with the binder powder, distributing the fiber and binder combination across the width of a forming conveyor, and melting the combination to fix the fiber with the binder.

An insulation product contains a layer of textile, rotary and/or flame attenuated fibers. A process for manufacturing the insulation product includes passing fibrous bundles of one or more of textile fibers and of rotary and/or flame attenuated fibers together through an apparatus that separates the fibers and the mixes the separated fibers. The bundles of rotary and/or flame attenuated fibers can be in the form of specially manufactured mats and/or can be production scraps. The resulting mixture of fibers is formed into a non-woven batt, mat, blanket, or board. The process provides homogeneous fiber product with an improved appearance. The textile fibers can enhance thickness recovery of compressed product. Blends of textile glass fiber with rotary and/or flame attenuated glass fiber exhibit an improved combination of thermal and acoustic insulating performance and adequate strength, at a low production cost.
摘要:
An insulation product is provided comprising an insulation sheet containing randomly oriented fibers bonded together. The sheet has first and second major surfaces and a pair of side portions. A nonwoven facing layer is bonded to at least one of the major surfaces. The nonwoven facing layer comprises randomly oriented bicomponent fibers, each of the bicomponent fibers including first component and second component portions. The nonwoven facing layer is bonded to the at least one major surface at least in part by a meltbond between the first component portion of the bicomponent fibers and the randomly oriented fibers in the insulation sheet.

A method is provided to produce fine diameter glass fibers with fewer defects through a combination of lower attenuating gas velocities and the use of spinners having more and smaller holes. The method uses a device for internal centrifugation of mineral fibers including a centrifuge equipped with a peripheral band perforated with orifices distributed in a plurality of annular zones arranged on top of each other, assuming that the centrifuge is in centrifugation position. The device includes at least two annular zones whose number of orifices per unit of surface area differs by a value greater than or equal to 5%, 10%, or 20%.

摘要:
The invention relates to curing a binder on fibrous insulation wherein, heated gas flows as a ratio of, an upward flow into the fibrous insulation, and a downward flow into the fibrous insulation, to heat the binder to its curing temperature; and the binder is cooled, thereby curing at least a portion of the binder to a thermoset state. When a remainder of the binder remains uncured, another stage of heating the binder with a ratio of heated gas followed by cooling, will cure the remainder of the binder.
