| titleOfInvention | Composite elastic fiber and preparation method thereof |
| abstract | the invention relates to a composite elastic fiber and a preparation method thereof, wherein the method comprises the following steps: and carrying out composite spinning on the thermoplastic elastomer with the melt viscosity ratio of 1-1.5: 1 and the thermoplastic elastomer with the low hard segment crystallization temperature according to the weight ratio of the components of 20: 80-80: 20 to obtain the composite elastic fiber. The composite elastic fiber has the elongation at break of 200-1000%, the elastic recovery rate is not less than 95%, the macroscopic self-curling crimp rate is 30-500%, the curling radius is not more than 2mm, the curling number of the fiber is 25-150/25 mm, when the tensile stress is not more than 0.05cN/dtex, the elongation of the fiber is 10-500%, and the deformation range of intrinsic entropy elastic deformation is 20-200%. The preparation method is simple in preparation process and low in cost, and the prepared composite elastic fiber has the advantages of high crimp rate, high elastic recovery rate, large elongation at break, low modulus and the like, and has wide application prospects. |
