| titleOfInvention | High-resilience urethane elastic fiber as well as preparation method thereof |
| abstract | The invention relates to a preparation method of a high-resilience urethane elastic fiber. The preparation method comprises the following steps: (1) mixing raw materials, namely, polytetramethylene ether glycol (PTMEG) and 4, 4-diphenylmethane diisocyanate (MDI) to carry out reaction so as to obtain a prepolymer; (2) adding a certain amount of a mixed diamine chain extender into the prepolymer to form polymer liquor; (3) quickly adding polyamine (the number of functional groups is greater than 2) into the polymer liquor while stirring to carry out reaction so as to form polyurethaneurea liquor; (5) carrying out reaction on MDI and polyether polyhydric alcohol and blocking with ethanediamine to prepare oligomers; (6) blending nano attapulgite with the oligomers to prepare a prepreg; and (7) mixing the polyurethaneurea liquor with the prepreg to prepare a spinning dope, and spinning to form the high-resilience urethane elastic fiber. The preparation method of the high-resilience urethane elastic fiber provided by the invention satisfies the demands on the high-resilience urethane elastic fiber in certain special fields, and the resilience of the urethane elastic fiber is improved. |
