Abstract:
A creped paper product is provided according to the invention. The creped paper product comprises a result of creping a web of fibers comprising synthetic fibers to provide a creped paper product having a stretch of at least 3% in the machine direction according to TAPPI test T494. The web of fibers can include about 0.5 wt. % to 100 wt. % synthetic fibers based on the total weight of the fibers. In addition, the web of fibers can contain about 0.5 wt. % to about 10 wt. % of synthetic fibers and about 90 wt. % to about 99.5 wt. % of cellulosic fibers. When the web of fiber includes a mixture of synthetic fibers and cellulosic fibers, the creped paper product can be provided having a tear strength in the machine direction according to TAPPI test T494 at least 10% greater than an otherwise identical creped paper product that does not contain synthetic fibers. A method for forming a creped paper product is provided according to the invention.
