    摘要： The present invention can provide a distinctive article which includes a plurality of fibers (62), wherein the fibers include a selected polymer, fiber material. In a particular aspect, the fiber material can exhibit a “low” crystallization rate. In other aspects, the fiber material has been subjected to a low fiber-draw percentage, and the polymer in the fibers can have a high crystallinity. Further aspects can include a fiber material which has been subjected to a low fiber-draw speed, and can include fibers which have a high tenacity. In still other aspects, the fibers can be configured to provide a fibrous web (60), and the fibrous web (60) can have a distinctive tensile strength quotient, with respect to tensile strengths along its machine-direction (22) and cross-direction (24).

    摘要： The present invention can provide a distinctive method and process for making polymer fibers (62) and nonwoven fabric webs (60). The method can include providing a fiber material that exhibits a low crystallization rate. In a particular aspect, the fiber material can be subjected to an anneal-quench at an anneal-quench temperature that approximates a prime-temperature at which the polymer material most rapidly crystallizes. In another aspect, the fiber material can be subjected to a fiber-draw at a selected fiber-draw temperature, and in a further aspect, the fiber-draw temperature can be configured to approximate the prime-temperature of the polymer material. In still other aspects, the fiber material can be subjected to a relatively small amount of fiber-draw, and the fiber-draw can be provided at a relatively low fiber-draw speed.
