Novel Porous Sheet Materials of Potential Suitability for Military Textile Applications.

摘要

Novel approaches to formation of porous sheets were considered as offering potential replacement, alternative or substitute materials for conventional textile applications. Some materials, processes and potential applications are suggested for further investigation. Fibers, continuous and interrupted film, and foam were found to be the elementary structures which offer suitable performance features in general and govern the particular characteristics. Fibrous web systems continue to appear as the most favorable and versatile. The most economical routes to the formation of nonwoven fibrous webs are integral with the initial extrusion of thermoplastic polymers, as in the spunbonded, sprayspun, meltblown, fibrillated film and fibrillated foam processes.
