摘要： An absorbent article having a liner adapted for contiguous relationship with the wearer's body, an outer cover in generally opposed relationship with the liner, and an absorbent body disposed between the liner and the outer cover. An absorbent structure of the absorbent body has a length, a thickness, a width, a longitudinal axis and a non-uniform lateral compression stiffness across its width. The non-uniform lateral compression stiffness is such that the absorbent structure assumes a pre-determined, or non-random buckled configuration under lateral compression thereof. In one embodiment, the buckled configuration is generally symmetric about a plane normal to the absorbent structure and in which the longitudinal axis of the absorbent structure lies.

摘要： A method for forming a biodegradable polyester suitable for use in fibers is provided. Specifically, a biodegradable polyester is melt processed at a controlled water content to initiate a hydrolysis reaction. Without intending to be limited by theory, it is believed that the hydroxyl groups present in water are capable of attacking the ester linkage of the polyester, thereby leading to chain scission or “depolymerization” of the polyester molecule into one or more shorter ester chains. By selectively controlling the reaction conditions (e.g., water content, temperature, shear rate, etc.), a hydrolytically degraded polyester may be achieved that has a molecular weight lower than the starting polymer. Such lower molecular weight polymers have a higher melt flow rate and lower apparent viscosity, which are useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.
摘要翻译： 提供一种形成适用于纤维的可生物降解聚酯的方法。 具体地说，将可生物降解的聚酯以受控的水含量熔融加工以引发水解反应。 不期望受理论的限制，据信存在于水中的羟基能够攻击聚酯的酯键，从而导致聚酯分子链断裂或“解聚”成一个或多个较短的酯链。 通过选择性地控制反应条件（例如水含量，温度，剪切速率等），可以获得具有低于起始聚合物的分子量的水解降解的聚酯。 这种较低分子量的聚合物具有较高的熔体流动速率和较低的表观粘度，其可用于多种纤维形成应用中，例如在非织造纤维网的熔喷中。

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).
