Title:
【発明の名称】モールド成形された絶縁製品および連続ウール繊維を用いたその製造
Document Type and Number:
Japanese Patent JP2001505960
Kind Code:
A
Abstract:
A process of forming a thermal insulation layer (34) includes advancing a multifilament strand of continuous filaments (12) through a nozzle (10) to separate the filaments (16) from each other to form a continuous-filament wool (14), applying a binder to the filaments, placing a charge comprising the wool in a mold (32), and molding the charge to form an insulation layer (34). In a preferred embodiment, the charge (30) further comprises a container, such as a bag (24) formed from a poylmer film. The filaments are preferably prepared from a high-strength, high-temperature resistant glass material. The molded wool is advantageously used to manufacture products, such as catalytic converters (46) wherein the wool is used to thermally insulate the catalytic core element (48).
