Problems solved by technology

[0004] Another problem with applying conventional binder materials is that applying the binder in liquid form has the potential to escape some of the binder material as volatile or particulate organic material, requiring costly environmental protection measures and equipment

Embodiment Construction

[0020] The soundproofing product of the present invention, as shown at 10 in FIG. The sound insulation product 10 is formed into a desired shape to meet the contours of a particular application or a shape required by the intended use of the sound insulation product.

[0021] As shown in FIG. 2 , the fibers of the sound insulation product 10 generally include multicomponent fibers in the form of primary fibers 16 and bicomponent polymeric fibers 20 . It will be appreciated that although bicomponent fibers are exemplified, other multicomponent fibers, such as tricomponent fibers, may also be used in the present invention.

[0022] For clarity, the bicomponent polymer fibers 20 are given in cross-section, while the main fibers 16 are not. The bicomponent polymer binder fiber 20 is composed of a base polymer component 22 and a binder polymer component 24 . The bicomponent polymer fiber 20 shown has been formed as a sheath-core fiber, with the base polymer component 22 forming th...

Abstract

An acoustical insulation product (10) for a vehicle includes a blanket of fibers (12) and a facing material (14) adhered to a major surface of the blanket. The product has a perimeter flange (70) made by pressing the facing material and an edge portion (72) of the blanket together. The flange provides stiffness to the product, and the flange is capable of being held in place on the vehicle by an attachment system.

Description

technical field [0001] The present invention relates to fibrous insulation products, and more particularly, the present invention relates to fibrous insulation products suitable for use as sound insulation layers in vehicles, such as under the hood of a truck. Background of the Invention [0002] Fiber insulation is typically created by fiberizing the molten material and depositing the fibers on a collection conveyor. Certain fibrous insulation products are produced by transporting the fibrous material through various secondary processes, such as wet processing, airborne processing, reorientation, carding, blending of different types of fibers, or other processes used to form a covering of fibrous material. Typically, the fibers used in insulation products are inorganic fibers, such as glass fibers, but some insulation products are made from organic fibers, such as polyester. Most fibrous insulation products contain a binder material to bind the fibers together when they co...
