MANUFACTURING METHOD OF HIGH-PERFORMANCE POLYURETHANEUREA ELASTIC FIBER

摘要

The present invention relates to a method for manufacturing polyurethaneurea. More specifically, in this method a prepolymer with a number average molecular weight of 800 to 1300 daltons is manufactured from glycol and a diisocyanate, and a chain extender is added to the prepolymer to form a spinning solution, which is then agitated and aged to spin high-performance polyurethane fiber.
