METHOD FOR PREPARING POLYURETHANEUREA ELASTIC FIBER WITH IMPROVED HEAT SETTABILITY AND POLYURETHANEUREA ELASTIC FIBER PREPARED BY THE SAME |
摘要 |
<p>The present invention relates to a method for preparing polyurethaneurea elastic fiber, the method comprising reacting a mixture of at least one diisocyanate comprising 4,4'-diphenylmethanediisocyanate and 7 to 25 mole % of 2,4'-diphenylmethanediisocyanate with polyol to produce a prepolymer, and polyurethaneurea elastic fiber prepared by the same. The polyurethaneurea elastic fiber of the present invention has superior spinning workability, improved yarn evenness, and high heat-set efficiency even at low temperature.</p> |
