ABSTRACT:
Provided is a high tear strength, high tensile strength paper product. The product comprises a wood pulp fiber, a non-cellulosic synthetic fiber having a tear strength enhancing denier and length, and a binder material. The resulting paper product exhibits a combination of tear strength and tensile strength which can equal that of cotton cloth of the same basis weight, and can therefore be used as a less expensive substitute for cotton cloth in many applications.
