HIGH PERFORMANCE NONWOVEN STRUCTURE

The presently disclosed subject matter relates to multi-layer nonwoven materials and their use in absorbent articles. More particularly, the presently disclosed subject matter relates to layered structures that have high absorbency performance while having less absorbent mass than other commercially available materials.

Medical protective clothing materials

Protective clothing materials and related methods and garments are provided. In some embodiments, a protective clothing material may comprise a fibrous layer that serves as a barrier to certain fluids (e.g., bodily fluids, water) and microbes. The impermeability of the fibrous layer may be due, at least in part, to the structural uniformity and/or relatively small pore size of the fibrous layer. In some embodiments, the fibrous layer may have a relatively high air permeability that imparts beneficial properties (e.g., relatively high air flow, breathability) to the protective clothing material without adversely affecting its protection rating. In certain embodiments, the protective clothing material may also comprise one or more coarse nonwoven webs that impart beneficial properties (e.g., splash resistance) to the protective clothing material. The protective clothing materials, described herein, may be particularly useful for a wide variety of applications, including the formation of AAMI level 4 protective garments.

BASE MATERIAL FOR MOLDING
20230021854 · 2023-01-26 · ·

The present invention relates to a molding base material (10) with which it is possible to prepare a vehicle exterior material such as an underbody shielding material. As a result of continued investigations, the applicant of the present application found that the objective of the present invention could be achieved by means of a “molding base material including a fiber base material layer (1) and a cover layer (3), wherein the fiber base material layer and the cover layer are integrally bonded to one another by means of a polypropylene-based resin layer (5) present at the interface between the fiber base material layer and the cover layer”, and wherein the fiber base material layer contains sheath-core type composite fibers of which the core portion is a polyester-based resin and the sheath portion is a polypropylene-based resin. That is, it was found, for example, that a vehicle exterior material prepared using a molding base material satisfying this composition does not readily suffer from inter-layer peeling under high-temperature conditions, and has excellent heat resistance.
