The present invention can provide a unique article comprising a plurality of fibers 62, including selected polymeric fiber materials. In certain aspects, the fibrous material may exhibit a "low" crystallization rate. In another aspect, the fiber material received a low% fiber-stretch, and the polymer in the fiber may have a high degree of crystallinity. Additional sides may include low fiber-stretching speed fiber material and may include fibers with high toughness. In another aspect, the fiber can be configured to provide a fibrous web 60, which has a unique tensile strength factor for its tensile strength along its machine direction 22 and transverse direction 24. Can be.n n n n Crystallization rate, crystallinity, fiber-drawing speed, tensile strength factor. |
