  • Heat-resistant laminated conveyer belt
    Patent number: 9643347
    Abstract: A heat-resistant laminated conveyer belt includes a fluororesin-coated core and a reinforcement layer which is formed on the core through an adhesive layer. The core is obtained by impregnating an aramid fiber woven fabric in a fluororesin dispersion and drying and sintering the fabric. The reinforcement layer is obtained by impregnating an aramid fiber woven fabric to which stretch properties are applied in a fluororesin dispersion and drying and sintering the fabric. The aramid fiber woven fabric of the core is a woven fabric by a plain-weave seamless loom or a circular loom. The aramid fiber woven fabric of the core includes an S-twist weft yarn and a Z-twist weft yarn which are alternatively arranged.
