Fiberglass-based materials and fire retardant compositions are described, wherein the fiberglass materials and the fire retardant compositions are encapsulated in a plastic cover. Methods for making encapsulated fiberglass articles are also described.

Fire resistant encapsulated fiberglass products

Disclosed are binders including urea-extended phenol-formaldehyde alkaline resole resins to which melamine-containing resin has been added, and non-woven fiber compositions made therewith. The disclosed binders may be cured to low formaldehyde-emission and low trimethylamine-emission, water-resistant thermoset binders.

Low formaldehyde emission fiberglass

A fibrous papermaking felt for carrying a paper web through a paper making process includes a resilient layer of glass fibers and a fabric backing layer.

Papermaking felts from irregular fibers

A method for forming an insulation product includes centrifuging irregular glass fibers using a rotary process, collecting the fibers as a pack, continuously withdrawing a portion of the fibers from the pack to generate a continuous yarn of fibers, and pneumatically propelling the yarn toward a receptacle, such as an insulation cavity, to form an insulation product. Also, a strand of continuous, irregular textile fibers can be payed out from a wound package and pneumatically propelled toward a receptacle, such as an insulation cavity, to form an insulation product.

Method of forming an insulation product

An irregularly shaped glass fiber is provided which enjoys improved resiliency, and openness in pack structures. Wool packs and other wool portions having such irregularly shaped fibers may be processed directly through needling to form a non-woven material without intervening steps such as carding or blending of fibers which accompany conventional glass fiber processing operations. In a further aspect of the invention, a non-woven material including irregularly shaped fibers in a generally continuous wool tow is produced by 'unwinding' a fiberglass wool pack collected by a direct forming method. Product applications include simplified, lower cost processing, and new uses of the irregularly shaped fibers produced by rotary fiberization in filtration elements, sorbants, gaskets, packings, shingles, composite structural elements, furnishings, textiles, yarns, and blown-in insulation systems.

Processing methods and products for irregularly shaped bicomponent glass

A fibrous product is produced by providing a collection of fibrous material, and encapsulating the fibrous material by covering the fibrous material with a film to form an encapsulated blanket of the fibrous material. The encapsulated blanket is then needled to cause entanglement of the fibrous material, thereby producing a needled, encapsulated fibrous product.

Needled encapsulated fibrous product

Fiberglass insulation having improved parting strength is prepared by forming a fiberglass mat, applying an aqueous acid aluminum phosphate binder, curing the binder, and autoclaving the resultant insulation batt.
