| titleOfInvention | Manufacturing Method of High Speed Spinning Polyurethane Urea Elastic Yarn |
| abstract | The present invention relates to a method for producing a polyurethaneurea elastic yarn, to prepare a prepolymer using a first polyol, a second polyol, a first diisocyanate and a second diisocyanate, and to add a chain extender to the prepolymer After the urethane urea polymer is obtained, it relates to a method for producing a polyurethane urea elastic yarn for high-speed spinning (spinning speed 1000 m / min or more) characterized by aging and spinning the obtained polyurethane urea spinning stock solution. The first polyol has a molecular weight of 1,000-2,000 level, the second polyol has a molecular weight of 2,000-3,500, each polyol is polyether glycol, polyester glycol, polypropylene glycol, 3-methyltetrahydrofuran type 1 or 2 One or more mixtures, the second polyol is present in the range of about 2 to about 35 mole percent of the total polyol. In addition, the first diisocyanate is one or two or more organic diisocyanates selected from aromatic, aliphatic and alicyclic diisocyanates, and the second diisocyanate is 1,4-bis (isocyanatomethyl) cyclohexane (1, 4-H 6 XDI), and the second diisocyanate contains about 2 to about 25 mol% of the total diisocyanate, and thus the polyurethaneurea elastic yarn prepared by the above method has excellent elongation of the yarn, and even if high-speed spinning Similar yarn properties can be obtained. <Index> Polyurethaneurea elastic yarn, 1st polyol, 2nd polyol, 1st diisocyanate, 2nd diisocyanate, high speed spinning |
