ABSTRACT:
A high-elasticity dewatering felt for use in e.g. papermaking and cellulose machines wherein the elastic properties of the felt are obtained by admixture thereinto of high-molecular thermoplastic elastomer materials, alternatively high-molecular cross-linked urethane-based elastomer materials, which elastomer materials are capable of stretching to at least twice their original length and subsequently, after relief of the load thereon, rapidly return to substantially their original length.
