Title:
POROUS YARN COMPRISING SYNTHETIC POLYMER * PRODUCTION THEREOF AND SUPPORT OR INSULATION MATERIAL MADE FROM SAID YARN
Document Type and Number:
Japanese Patent JPS5522097
Kind Code:
A
Abstract:
A mixture comprising at least two components of which one is a fusible polymer and the other is a liquid which is inert towards the polymer, the two components being such as to form a binary system having in the liquid state, a region in which they are totally miscible and a region in which there is a discontinuity in mixing, is extruded at above the critical temperature of the binary system into a bath of the inert liquid component having a temperature below the critical temperature and the thread structure formed is solidified. The inert liquid may be washed out by a solvent eg acetone. The fusible polymer may be polypropylene and the inert liquid N, N-bis-(2-hydroxyethyl)- hexadecylamine.
