METHOD OF SPINNING FIBERS FROM DISPERSION OF POLYTETRAFLUOROETHYLENE AND RELATIVE POLYMERS |
摘要 |
polymer materials. SUBSTANCE: invention relates to manufacture of fibers from fluorinated polymer dispersion, wherein structure of intermediate fibers immediately before their sintering contains basically ions characterized as volatile ions, which are ions and partially ionized compounds and, on heating to temperatures above 25 C but below temperatures causing coalescence of fluorinated polyolefin particles, volatilize or degrade into only volatile substances or carbonaceous residues. EFFECT: optimized spinning process. 6 cl, 2 ex
