METHOD FOR PRODUCING A NONWOVEN FABRIC USED AS AN ENGINE HOOD INSULATOR MATERIAL
20220025565 · 2022-01-27 ·

A coated nonwoven product used to make engine hood insulation material is produced by a method which involves needle punching a carded, cross-lapped web, then calendering the resulting web and then applying a foam coating. Rotary screen printing is used to apply a dot pattern of an acrylic emulsion to the dried, foam-coated web. Thermoplastic and/or thermoset material is deposited onto the acrylic coating and excess material is removed by vacuum, leaving a corresponding dot coating pattern of said material. The coated web is heated using infrared energy before cooling, cold calendering and winding-up.

Resilient, Multi-Layered Wiping Product

A multi-layered web is disclosed that is resilient and/or elastic in the Z-direction. Thus, when the web is compressed, the web assumes a compacted state and then expands to an expanded state when the compressive forces are removed. In one embodiment, the multi-layered web includes a middle layer made from a resilient blend of fibers positioned inbetween two outer layers. The middle layer, for instance, can contain elastomeric fibers, three-dimensional fibers, and/or debonded fibers.
