본 발명은, 다층 티슈 웹, 및 이를 포함하는 티슈 제품을 제공하며, 이는 다층 웹의 하나 이상의 외부층에 선택적으로 피착된 길고 높은 조도의 목재 펄프 섬유를 포함한다. 놀랍게도, 하나 이상의 외부층에, 심지어 비교적 적은 양으로 길고 높은 조도의 목재 펄프 섬유를 배치하면 유연성에 부정적인 영향을 미치지 않으면서 내구성과 같은 특정 제품 특성을 개선할 수 있다. 소정의 예에서, 유연성과 내구성 둘 다, 외부층 중 하나 이상에 길고 높은 조도의 목재 펄프 섬유를 선택적으로 포함시킴으로써 개선될 수 있다. The present invention provides mufti-layered tissue webs, and tissue product comprising the same, comprising long, high-coarseness wood pulp fibers selectively deposited in one or more outer layers of the multi-layered web. Surprisingly disposing long, high-coarseness wood pulp fibers in one or more outer layers, even in relatively modest amounts, may improve certain product properties, such as durability, without negatively affecting softness. In certain instances, both the softness and durability may be improved by selectively incorporating long, high-coarseness wood pulp fibers in one or more of the outer layers.
