Abstract

See full text

Disclosed is an elastic composite fiber, comprising a fiber body, wherein according to weight percentage, the material composition of the fiber body is made by composite spinning 10%-90% low viscosity PET, 10%-90% high viscosity PET, 10-80% PTT and 10-80% PBT. The present invention combines the advantages of the PET, PTT and PBT fibers into one, and not only has the advantages of good spinnability, high strength, good elasticity, softness, comfortableness, easy dyeing, moisture absorption and the like, but also utilizes reasonable cooperation between materials and the difference between physical and chemical properties to make the three-dimensional structure of the composite fiber more remarkable and the thermal stability better.
