Abstract
Reinforced fiber insulation is formed by depositing a mixture of textile fiber segments and rotary and/or flame attenuated segments on a surface, mixing a binder with the fibers, and heating the binder to join the fibers together. The low cost process provides a mixed fiber insulation product with improved strength after compression.
Claims20
A method of forming reinforced fiber insulation, the method comprising
- spinning first fibers each having a diameter of from about 3 μm to 5 μm and a length of from about 1 cm to about 5 cm;
- providing second fiber segments each having a diameter of from greater than 5 μm to about 16 μm and a length of from about 2 cm to about 15 cm;
- depositing a mixture of the first fibers and the second fiber segments on a surface;
- mixing a binder with the first fibers and the second fiber segments;
- forming the first fibers, the second fibers segments, and the binder into a primary mat;
- heating the primary mat to cause the binder to bond together the first fibers and the second fiber segments;
- and
- forming the reinforced fiber insulation.
