| 摘要 |
The invention is directed to a synthetic fiber thermal insulator material in the form of a flexible, conformable, sheetlike structure, which structure comprises an assemblage of: (a) from about 50 to 100% by weight of slickened, spun and drawn, crimped staple polymeric microfibers having a diameter of from about 3 to 12 microns; (b) from about 0 to 30% by weight of unslickened, spun and drawn, crimped staple polymeric microfibers having a diameter of from about 3 to 12 microns; and (c) from about 0 to 30% by weight of synthetic polymeric macrofibers having a diameter of from about 12 to 50 microns, wherein at least some of the fibers are bonded or mechanically interconnected one to another, and wherein the resultant fiber assemblage has a thermomechanical parameter T greater than about 0.25 (m2?K/W?m)/(mN?cm). |
