  • Patent number: 5891516
    Abstract: Fiber cement felts of the present invention include: a top fabric layer that includes fine machine direction yarns and fine cross machine direction yarns interwoven with the fine machine direction yarns; a bottom fabric layer underlying the top fabric layer that includes coarse machine direction yarns and coarse cross machine direction yarns interwoven with the coarse machine direction yarns; and a batt layer attached to and overlying the top fabric layer. Preferably, the top fabric layer is heat bonded to the bottom fabric layer. It is also preferred that the fiber cement felt of the present invention include a second batt layer that underlies the bottom fabric layer. In this multiple layer structure, the felt can have higher tenacity, improved resistance to blinding and compaction, and a reduced tendency to mark a fiber cement sheet during its formation.
